  Water is the foundation of human existence. March 22nd is the 26th World Water Day and the beginning of the 31st China Water Week. This year, the United Nations decided that the propaganda theme of "World Water Day" was "Borrowing force of nature to protect green mountains and green rivers". The propaganda theme of "China Water Week" is "Implementing national water-saving actions and building a water-saving society". What measures and effects does China have on water conservation?

  ■ There are many activities in love the water.

  In the south of spring, willow branches are swaying and flowers are blooming. On March 22nd, the activity of "Taihu Cup Looking for the Guardian of Rivers and Lakes Around" was held in Nanjing Youth Olympic Cultural Park, Jiangsu Province. "I witnessed with my own eyes that the river at my doorstep is getting cleaner and the environment is getting more and more beautiful." Ms. Liu, a citizen who came to participate in the event, said, "I hope I can do something."

  Many cities take World Water Day and China Water Week as an opportunity to carry out publicity and experience activities and contribute to the construction of water-saving cities.

  Zhejiang Hangzhou Water Group launched the "Water Supply Open Day" to help citizens understand the production and operation of urban water supply and drainage, environmental water distribution and maintenance and other related projects, and the staff of water supply enterprises answered questions from zero distance.

  Wuhan Jianhe Middle School in Hubei moved the geography class to the Yangtze River levee. The teacher scooped up two bottles of river water, so that the students could watch the color and smell it and have a quiz on water knowledge.

  ■ The industry can’t save water less.

  In recent years, from agriculture, industry, service industry to urban domestic water, the utilization efficiency and benefit of water resources in China have been steadily improved. According to the data provided by the Ministry of Water Resources, from 2012 to 2016, the water consumption per 10,000 yuan of GDP and industrial added value decreased by 25.3% and 26.6% respectively, and the effective utilization coefficient of farmland irrigation water increased from 0.516 to 0.542.

  The agricultural sector, which exceeds 60% of the total water consumption in the country, has achieved remarkable results in water saving. "I used to water the land, but now I water the seedlings." In the greenhouse of Gobi Agricultural Industrial Park in Suzhou District, Jiuquan City, Gansu Province, fist-sized tomatoes are covered with green branches. In this Gobi desert, which was once lamented as "the barren land in the middle of Gansu is the best in the world", the surface pipeline system and emitters drip water evenly and slowly into the soil at the root of crops. The application and popularization of new agricultural irrigation technology has greatly improved the efficiency of agricultural water use. By the end of 2017, the country had added more than 100 million mu of high-efficiency water-saving irrigation area. In the past five years, the effective utilization rate of farmland irrigation water has saved 20% to 50% compared with traditional irrigation.

  In the industrial field, the state continues to promote water-saving processes, technologies and equipment, focusing on the implementation of water-saving technological transformation in high-water-consuming industries. In the service industry, we will implement water-saving technological transformation of high-water consumption service industries and strictly control high-water consumption service industries such as bathing and car washing. At the same time, strengthen the transformation of urban public water supply pipe network, comprehensively carry out the construction of water-saving units and residential quarters, and create an atmosphere of saving water for all.

  ■ Institutional innovation manages the long term.

  "Look at the new river now, with clear water and fish shuttling. Wait another year, and at the junction of the three rivers, a new Weisha Wetland Park covering an area of 5,000 mu will be built soon. " On March 20th, Shu Quanhai, deputy director of Diaotai Sub-district Office in Fengxi New Town, Xixian New Area, Shaanxi Province, stood at the intersection of the new river and the Weihe River to inspect the river. He comes to this place two or three times a week.

  Shu Quanhai said that since the implementation of the river length system, the effect of river management in the jurisdiction has been very obvious. At present, there is basically no surface garbage in the river.

  It is reported that at present, 25 provinces in China have established the river length system, and the remaining provinces and Xinjiang Production and Construction Corps will be fully established by the end of June this year, and more than 320,000 river lengths at the provincial, city, county and township levels have been identified. There are 2865 lakes with a water area of more than 1 square kilometer in China. At present, 2180 lakes have established the lake length system, and it is planned to fully establish the system before the end of this year.

  "Implementing the responsibility system for the heads of rivers and lakes is not a short-term expedient measure, but an institutional innovation with far-reaching significance in the water management system." Jia Shaofeng, a researcher at the Institute of Geographical Sciences and Resources, Chinese Academy of Sciences, said.

  Innovative systems such as river length system and lake length system provide a guarantee for long-term and effective water resources protection and management. By introducing the river length system in many areas, the water quality has been obviously improved, and the appearance of rivers has been greatly improved. The beautiful picture of smooth rivers, clear water and green shores is becoming a reality. (Li Wei Lu Anqi Shi Hongqiang)

The opening of "IELTS Middle School Teacher Training Course" was appreciated by teachers.

[Source: Educational Information]
According to the 2019 IELTS White Paper, IELTS candidates in Chinese mainland continue to be younger, and IELTS candidates under 18 have become the second largest age group. The pain point of middle school English teaching is gradually revealed in the IELTS learning of middle school students, mainly because the supply side can not match the underlying academic support of the demand side. How to get out of the IELTS dilemma of middle school students was once a hurdle for all English education experts.
It is reported that on June 26th, 2019, the British Council, Foreign Language Teaching and Research Press and Tudou Education jointly launched the "New English Teaching Scheme for IELTS Middle School", which aims at cultivating the core literacy of middle school students’ English subjects, aiming at improving the teaching level of IELTS English and the comprehensive application ability of middle school students. The main contents include three modules: IELTS Middle School Course, training course system, assessment tools and services.
In August of the same year, the offline course of the first "IELTS Middle School Teacher Training Course", which was jointly created by FLTRP and Tudou Education and aimed at improving the teaching level of IELTS middle school teachers, started in Beijing. At the end of November, the second offline course of "IELTS Middle School Teacher Training Course" started in Nanjing. Once the registration news of the training course was released, it was strongly welcomed by many foreign language schools, international schools and IELTS training institutions across the country. The training courses have also been highly appreciated by teachers.
Potato Education was invited by FLTRP to train more than 1,000 teachers in 100 foreign language schools across the country.
This spring semester, many teachers didn’t finish their first class on the podium. In order to prevent the epidemic from spreading to the campus, online classroom has become a new key word. In order to actively respond to the epidemic situation in novel coronavirus, implement the epidemic prevention and control work requirements of the Ministry of Education, and ensure "no classes to stop learning" and "no classes to stop training", Potato Education gave full play to its core academic and technical advantages, and launched the national teacher training online for the first time. From March 5th, the IELTS Middle School Course will be systematically demonstrated and explained online for 1,300 teaching and research backbones and English teachers from hundreds of foreign language schools.
It is understood that Tudou Education is an innovative education company driven by both academic and technical, and Tudou hopes to bring advanced teaching concepts to all middle school English teachers. In the special period of epidemic prevention and control, Potato Education has made precise policies. This IELTS middle school teacher training can realize live training through mobile phone or Pad. Dr. Tsinghua University, deputy editor-in-chief of IELTS Middle School Course, and teacher Yang Chongsheng, the head of potato IELTS teaching and research, have been teaching IELTS for 13 years and have been deeply involved in the teaching of English ability for K12 people, especially middle school students.
In the live training on March 5, Teacher Yang Chongsheng first made a detailed interpretation of the development trend of IELTS test in China in recent years and the trend of candidates’ overall ability level. Then, it systematically explains the writing concept, course content and supporting resources of IELTS middle school course, and shows the teaching method of IELTS middle school course from the teaching practice, which provides multi-dimensional guidance for teachers on how to improve the interactivity of content explanation in the teaching process.
More than 1,300 teachers from 100 foreign language schools across the country had a very active interaction, throwing out practical problems and difficulties encountered in English teaching at ordinary times, covering practical cases of improving the ability of listening, speaking, reading and writing in all dimensions, and getting answers and analysis from Teacher Yang one by one; In addition, Mr. Yang also gave a further interpretation of the "effective landing of core literacy" advocated by the English Curriculum Standards for Ordinary Senior High Schools (2017 Edition), which pointed out a clearer teaching direction for online trained teachers nationwide.
After the training, teachers have called for the training to continue, and said that continuous "charging" can provide a steady stream of confidence for IELTS teaching in the future and better improve the teaching quality. With the continuous expansion of the younger IELTS population, the demand for IELTS learning in middle school students is soaring, and teachers need to strengthen the standardization and systematization of IELTS teaching. Systematic teacher training for IELTS Secondary School Course will actively promote the teaching of competency-based English in middle schools, resolve the contradiction of IELTS teaching for middle school students, and provide a platform for teachers to improve IELTS teaching and further study.

Ludian, Yunnan: Ten thousand mu of cherry flowers are in full bloom.


  Original title: "Zhaotong Impression" in Spring | Ludian, Yunnan: Ten thousand mu of cherry flowers are in full bloom.

 

  Spring is full in February, and flowers are blooming. A few days ago, 10,000 mu of cherry blossoms in Xiaozhai Town, Ludian, Yunnan Province, were in full bloom, clusters and clusters, covered with branches, just like white snow, which reflected each other with Qingshan village, fresh and pleasant, and made it a quiet and peaceful beautiful countryside scene.

Why is fruit so expensive this spring? The reason behind the reporter’s investigation

  The price of fruit has gone up sharply this spring. According to the relevant data of the Ministry of Agriculture and Rural Affairs compiled by Zhuo Chuang Information, the wholesale price of fruits from January to April in 2022 was higher than the average price in the past nine years, and it showed a continuous upward trend.

  From the place of origin to the dining table, fruits have to go through the stages of fruit farmers’ picking, packaging and purchasing, loading and transportation, wholesaler sales, etc., and finally reach the fruit shop at home. Qianjiang evening news Hour reporter interviewed producers, wholesalers, logistics drivers and store operators, trying to explore the deep-seated reasons behind these links.

  Many people are concerned about when the price of fruit will come down. According to the prediction of fruit farmers and wholesalers in producing areas, with the coming of summer fruit ripening season, the wholesale price of fruit will soon fall, and the price of retail stores will naturally fall.

  Due to climatic reasons, the reduction in production and the sharp drop in imported fruits cannot fill the gap.

  Most of the fruits in this season are from Yunnan, Hainan and other places, because the reduction in production has led to an increase in wholesale prices.

  According to Hong Lianggang, the wholesaler of Hangzhou Fruit Wholesale Market, the price of wogan rose from 4 yuan to 11 yuan, honeydew melon from 12 yuan to 20 yuan, mango from 4 yuan to 10 yuan, and the most outrageous thing was watermelon. A while ago, the price of watermelon rose from 6 yuan to 20 yuan.

  Chen Ying (pseudonym), who is purchasing fruits in Hainan, explained the reason to qianjiang evening news Hour reporter: "The winter in Hainan this year is particularly long. Due to the influence of cold air, the output of lotus spray, Guifeimang and litchi here has decreased a lot."

  Mid-May is the season when a large number of lychees are listed in Hainan. In previous years, the local wholesale price was only five or six yuan a kilogram, but this year, the wholesale price of lychees rose to 14 yuan a kilogram, and the price doubled 1.5 times.

  Before the local fruits were ripe for the market, the output of foreign fruits was reduced. In the past, this situation also happened. The solution for wholesalers was to fill the gap with imported fruits.

  But this year, the number of imported fruits has also dropped sharply.

  At Hong Lianggang’s wholesale point, the sales of imported fruits accounted for 30% of the total sales in previous years, and now it has dropped sharply to 10%.

  The origin of imported fruits this season is mainly Southeast Asia. Last year, 7.5 kilograms of mangosteen with a box of 200 pieces sold 450 pieces this year; Last year, 15 kilograms of durian with an average price of about 400 yuan per box sold directly to 800 yuan this year.

  The epidemic affected the transportation time, and the freight cost generally increased by 10 times.

  The reduction of production makes the price of fruit higher, and the increase of transportation cost adds a fire to the rising price.

  According to Chen Ying’s estimation, in previous years, the freight for a car full of princess smiles was 9,000, but this year it has become 12,000. Affected by the local epidemic this year, the passage of trucks was not as smooth as in previous years, and the freight rate naturally rose.

  Liu Ben (a pseudonym), a truck driver, took a load of bananas imported into Hangzhou fruit wholesale market. His batch of bananas was shipped from the port of Ningbo. Originally, this journey only took three or four hours, but now it takes three days.

  Imported fruits need to go through customs inspection, disinfection and nucleic acid detection, and so on. Just here at the customs, it will take a day. When the goods arrived at the highway bayonet, Liu Ben had to hand over the driver’s license to the staff. "Because it is stipulated which highway intersection to get off from, you must return from which highway intersection."

  When you get to the market, people and goods need a 24-hour nucleic acid report to enter the market. Liu Ben drove the car to Hangzhou Renhe Inspection Station and tested the bananas. Liu Ben himself went to the hospital to do nucleic acid, and when the report came out, another day passed.

  Liu Ben calculated that it would take about 140 liters of oil to get from Ningbo to Hangzhou. This year, the oil price has risen, and he can only bear it himself. Together with the toll of 336, it costs 672 yuan to go back and forth. After deducting these costs, Liu Ben can only earn 500~600 yuan for one trip.

  The epidemic situation makes it impossible for goods between markets to circulate and transfer at will. "Every batch of fruit we have now has a traceability code, which can only be sent straight from the place of origin and cannot be transferred. In the past, we would look at the price. For example, if the goods in Jiaxing market are cheaper, we will adjust from Jiaxing, and now it is not allowed. " Fei Ge (a pseudonym), the wholesaler owner of Hongshi Fruit Industry, said.

  Feige is mainly engaged in the wholesale of fine fruits. Due to the difficulty of freight transportation in Shanghai, all the imported fruits were transferred to the docks in Guangzhou, which increased the transportation cost for the Hangzhou market.

  The number of imported fruits has dropped sharply this year, mainly due to the international epidemic.

  "I think many colleagues who are imported fruits are saying that the freight of imported fruits has generally increased by 10 times." Brother Fei said, "And in Southeast Asia and other countries where we mainly import fruits and fruits, almost all the automobile transportation routes are shut down, leaving only sea routes. The time for these fruits to stay on the cargo ship has increased, resulting in a decline in quality. "

  Store rent, labor cost factor, local fruit listing price will be lowered.

  The rise in wholesale prices makes the price tag of fruit shop stores change almost every day.

  "Recently, many customers have complained to us that fruit has become more expensive." Xiao Wu, a clerk of Huaxia Fruit Industry, pointed out and smiled at the concubine in front of the store. This is litchi that just came in, and the price is 51.6 yuan a kilogram.

  Most customers are still sensitive to price, so although the price of fruit has increased, the turnover has not increased, but has decreased.

  Sun Liying, the boss of Huaxia Fruit Industry, told qianjiang evening news Hours that the turnover of his three stores was only about one-third of that of the same period last year, and the passenger flow was also much less.

  Sun Liying has been a fruit store for 7 years, and now he has 3 stores in Hangzhou. The rent of the oldest No.1 shop has risen from 50,000 to 178,000 years, and the growth rate has increased by 5% year by year. The labor cost employed in the store accounts for 60% of the total expenditure. Sun Liying thinks that compared with these, the price of fruit has risen the slowest.

  In 2020, Sun Liying’s store enjoyed the government rent reduction and exemption policy, exempting the rent for three months and halving the rent for three months, which made him through the most difficult period.

  This year’s epidemic situation is complicated. Last month, two of his stores were shut down due to epidemic prevention and control, and some fruits were lost. "It’s good to live." Sun Liying said.

  However, the epidemic has also increased the sales of storable fruits such as apples, pears and bananas, and the prices of these fruits are relatively stable.

  Many people are concerned about when the price of fruit will come down.

  Hong Lianggang said that when local fruit production comes up, the wholesale price of fruit will soon fall, and the price of retail stores will naturally be lowered.

  Take watermelons as an example. In April, watermelons were scarce, and the wholesale price once rose to 18 yuan a kilogram. However, with the maturity of local sweet potatoes in May, the price of watermelons will drop to 4 yuan a kilogram.

  "I don’t know, one price a day." A stall owner who sold watermelons for 7 years in Hangzhou Fruit Wholesale Market said.

Year after year, is the Lantern Festival as you remember it?

  Reference message networkReported on February 19 Today is the rain in the solar terms in China, and it is also the last important festival in the Spring Festival customs — — Lantern Festival.

Illustration 1

  In June 2008, the Lantern Festival was selected as a national intangible cultural heritage. This traditional festival celebrated by China people has attracted worldwide attention.

  So, what is the China Lantern Festival in the eyes of foreign media? With this question, Xiao Bian put down the dumplings in his hand and opened the old newspaper of Reference News. While looking for foreign media reports on the Lantern Festival, he felt all kinds of changes and invariants in the development of the times … …

  In 2006, the online edition of The Times published an article entitled "Every household adheres to the ancient custom of eating Yuanxiao", which recorded the Lantern Festival time of a family in Beijing:

  "Wang wrapped in thick cotton-padded clothes and his mother stood in line for half an hour in the cold just to buy a bag of old brand Yuanxiao. The mother said: ‘ Such hard work is worth it. You have to eat Yuanxiao today, because it is a symbol of family reunion. ’”

  The word "stick to it" in the title of this article impressed Xiaobian. Why should we "stick to it" when eating Yuanxiao?

  Combined with the social background at that time, this problem is not difficult to understand. At that time, foreign festivals, commonly known as "foreign festivals", began to occupy a place in the lives of ordinary people in China, and even triggered a query that "traditional festivals are no match for foreign festivals".

  The most typical ones are Valentine’s Day and Lantern Festival. A "foreign festival", a traditional festival, is very close to each other every year: for example, the Lantern Festival is the second day of Valentine’s Day in 2003, and there is only one day between Lantern Festival and Valentine’s Day in 2006. The closeness of the two festivals made the topic of sticking to traditional festivals more prominent.

  For example, in an AFP article entitled "China people celebrate Valentine’s Day and Lantern Festival successively" in 2003, it was mentioned that China people celebrated Valentine’s Day with double joy this year, because people could celebrate the traditional Lantern Festival after Valentine’s Day at the same time.

  The media said that "since opening to the outside world, China has been more and more keen on Valentine’s Day". Although February 15th (Saturday) was the Lantern Festival that year, many people hung lanterns on the evening of 14th (Friday) to celebrate Valentine’s Day and Lantern Festival at the same time.

  After a lapse of three years, the Financial Times in 2006 also celebrated the "Foreign Festival" with "China in vogue"? It is reported that although China today is more confident and tolerant, not all China people are happy or optimistic about the fashion change of "foreign festivals" for young people. The newspaper mentioned a China person who rightly said: "Even if Valentine’s Day and Lantern Festival in the West are close this year, it can’t make ‘ Lover’s mood ’ Squeeze ‘ Celebrate the whole world and have fun with the people ’ The cultural connotation. "

  Today, 15 years later, when we look at the reports at that time, we may not feel so strongly about this topic. In Xiaobian’s view, even though China people have become accustomed to some "foreign festivals", their enthusiasm for traditional festivals such as the Lantern Festival has not diminished at all.

  Moreover, it has been proved that the traditional Lantern Festival custom has not faded with the progress of the times.

  In 2013, united press international reported that in Pingyao, Shanxi Province, every household hung red lanterns and set off fireworks to celebrate the Lantern Festival.

  Sarah brown, an Australian tourist, said, "We came to Pingyao from Beijing and felt the different atmosphere of the Lantern Festival. The atmosphere in Pingyao is more cheerful. It’s easy to get separated from friends in such a bustling street … … We feel the charm of the China Lunar New Year. "

  At that time, AFP reporters came to Nuanquan Town, Hebei Province, and recorded the local people’s way of ending the Lunar New Year with a unique "Da Shu Hua Show" performance.

  According to the report, this way of celebrating Lantern Festival, invented more than 300 years ago, is one of many ancient folk activities in China that have been restored in recent decades.

  AFP reporter recorded the process of the performance: the master who performed "Da Shu Hua Show" only "equipped" the straw hat and protective glasses. They scooped molten iron out of the bucket and splashed it on a brick wall. The iron flowers splashed on the brick wall, which was very spectacular.

  According to the report, this spectacular scene caused deafening cheers from the audience in Wenquan Town. Wenquan Town is only a few hours’ drive from Beijing. In order to promote the development of tourism, Wenquan Town resumed this folk activity with a history of hundreds of years.

  Of course, with the restoration of traditional folk customs, the way to celebrate the Lantern Festival is also changing in another way.

  In a report in 2017, the online reporter of Hong Kong Asia Times mentioned that when the Lantern Festival was held in Changzhou, Jiangsu Province in 2016, there was a beautiful electronic light show at the local Chinese Dinosaur Park, but it was not a traditional lantern, and of course there were no riddles.

  Spain’s Effie also noticed a new way to celebrate the Lantern Festival. The agency reported in 2016 that in order to celebrate the Lantern Festival, many people visited the Longqingxia Ice Lantern Art Festival in Yanqing District, Beijing. As one of the competition areas of Beijing 2022 Winter Olympics, many ice sculptures at the festival are sports-oriented.

  Mr. Jiang, a tourist, came here with his family for the holiday. He said that although these ice sculptures are a little far from the traditional Lantern Festival celebration elements, he feels: "We should keep pace with the times, and these are very special." Mr. Jiang said: "Of course, this is not a traditional way to celebrate, but we like it very much, and the children are also very interested in ice sculptures", especially the ice sculptures with the theme of the 2020 Olympic Games.

  "With the development of economy and society, China people’s Chinese New Year activities are gradually changing to a more modern form." Effie commented.

  Of course, the Effie reporter also noticed that in Zhangjiakou, Hebei Province, not far from Beijing, the celebration activities are much more traditional. Besides singing and dancing in traditional costumes, there are also traditional folk activities such as walking on stilts.

  In short, Xiao Bian believes that both adhering to the traditional customs and exploring the modern ways of celebrating the Lantern Festival express China people’s persistence and love for the traditional festivals.

The road to recovery is hindered by many obstacles. When will the rain and sunshine return to the south on a large scale next week?

Today, the scope of freezing weather in the south has been reduced, and the intensity has weakened. The Central Meteorological Observatory has lifted the yellow warning of freezing this morning and issued the freezing warning for five days in a row, which has finally come to an end. However, the low-temperature warning continues to take effect. Today, the temperature in the north and south is still "upside down" during the day. North China and northwest China are warmer than Jiangnan. With high humidity, many local partners in the south have experienced a 360-degree wet and cold attack without dead ends.

Next week, for the southern region, the range of rain and snow is still not small, and the precipitation in the north will also increase, mainly snowfall. According to the medium-term forecast of the Central Meteorological Observatory, it will be rainy in the south in the next 10 days, and the cumulative precipitation days can reach 5 to 7 days. The central and western parts of the south of the Yangtze River, the western part of South China and Guizhou have the most frequent precipitation, such as the rainy weather in Guilin, Guangxi. Among them, the warm and humid air flow strengthened on the 28th, while the cold air went south, the precipitation range expanded northward, and the precipitation intensity in the south strengthened briefly. On March 1, the precipitation contracted sharply to the south, and most of the south may wait for the long-lost sunshine next weekend.

In terms of temperature, it has experienced a trough. Although the temperature in all parts of the country is rising in the next few days, the pace of warming is relatively slow, and most areas will remain in a colder state than normal. Due to the influence of rain and snow in the south, the road to recovery is more difficult, and the state of low temperature is more obvious. In the next three days, the daily average temperature in southeastern Hubei, western and south-central Jiangxi, eastern and south-central Hunan, most of Guizhou, most of Guangxi, and northwestern Guangdong will be 5℃ to 7℃ lower than normal, and the temperature in southern Hunan, southeastern Guizhou, and northeastern Guangxi will be more than 7℃ lower, with a large and long-lasting low temperature and a heavy wet and cold feeling.

In addition, it should be noted that the temperature in South China will usher in a wave of obvious shocks next week. The warm and humid airflow will be strengthened from 28th to 29th, and the temperature in South China will rise sharply for a short time, with the highest temperature rising above 20℃ or even exceeding 25℃, but then it will drop sharply and return to more than 10 degrees, with great fluctuation. For example, in Fuzhou, the highest temperature will be less than 15℃ in the next three days, rising to 27℃ on the 29th and dropping to 13℃ on March 2nd. It is suggested that friends in South China should pay more attention to the weather forecast next week, adjust their clothes in time according to the temperature changes, and don’t accept thick clothes.

It is expected that after March 2, the temperature in the north and south will start to rise obviously, and gradually rise to the normal level in the same period of the year. At that time, everyone will feel the approach of spring.

Olympic observation China women’s volleyball team aims to defend its title. "We have waited for five years, and we are ready!"

Volleyball officially became an Olympic event at the Tokyo Olympic Games in 1964. China women’s volleyball team won gold medals at the Los Angeles Olympic Games in 1984, the Athens Olympic Games in 2004 and the Rio Olympic Games in 2016. It is the only Olympic champion team in China’s "three big balls" event. The 2020 Tokyo Olympic Games is about to open. As the defending champion, head coach Lang Ping will lead China women’s volleyball team to attack the Olympic champion again!

Lineup: Lang Ping hopes that these 12 people are the best choice.

The 12 players of China women’s volleyball team in Tokyo Olympic Games are: Zhu Ting, Zhang Changning, Li Yingying and Liu Xiaotong as main attackers, Yuan Xinyue, Yan Ni and Wang Yuanyuan as auxiliary attackers, Ding Xia and Yao Di as second setters, Gong Xiangyu, Liu Yanhan and Wang Mengjie as free men.

Among them, the oldest is Yan Ni, 34, and the youngest is Li Yingying, 21, born after 00. Zhu Ting, Zhang Changning, Liu Xiaotong, Yuan Xinyue, Yan Ni, Ding Xia and Gong Xiangyu are the champions of Rio Olympic Games, while Li Yingying, Wang Yuanyuan, Yao Di, Liu Yanhan and Wang Mengjie participated in the Olympic Games for the first time. Judging from the list, all the main core players in the women’s queue are selected, but in the selection of the substitute lineup, Lang Ping is still stable.

Regarding the formation of the list of 12 players, Lang Ping said: "This list has been brewing for a long time, and the whole coaching team is discussing what kind of suitable and complementary lineup should be used to appear in the Tokyo Olympic Games. I also hope that this list is our best choice, and I hope that these 12 athletes can represent all the athletes participating in the training and play their best level. "

Prepare for war: encourage each other to survive the hardest days.

In the 2019 Women’s Volleyball World Cup, Lang Ping led the team to successfully defend its title with an unbeaten record of 11 consecutive victories. This is the tenth championship won by China women’s volleyball team in the three world competitions (Olympic Games, World Championships and World Cup), and it also laid a solid foundation for the upcoming Olympic defending tour.

However, due to the COVID-19 epidemic, the Tokyo Olympic Games was forced to postpone, the FIVB also suspended all international competitions, and the China women’s volleyball team conducted training for seven months without an international competition. "In the most difficult days, we were completely enclosed, relying on each other’s support and companionship." Lang Ping said with emotion, "Thank you for your persistence and hard work. In the days when there was no competition at all and only boring training was left, we still encouraged each other and practiced every day as much as possible, helping our team gain valuable experience in a special period."

On May 1st, 2021, China defeated Japan 3-0 in the women’s volleyball competition on the first day of the Tokyo Olympic Volleyball Test. The picture shows China player Zhu Ting (right) spiking in the game. Xinhua News Agency reporter Du Yiyi photo

In May this year, the volleyball test match of Tokyo Olympic Games was restarted. As the only invited team, China women’s volleyball team played a test match with Japanese women’s volleyball team in Youming Gymnasium, the venue of Tokyo Olympic Games. In the end, China beat its opponent 3-0. This test match is of great value to China women’s volleyball team, which not only adapts to the Olympic venue in advance, but also makes the players who have not participated in international competitions for more than a year find their feelings on the field.

At the end of May, the 2021 World Women’s Volleyball League was held in Rimini, Italy in the form of "safety bubble". China women’s volleyball team sent a substitute team to participate in the first stage of the competition. Although the team only achieved 4 wins and 5 losses, more substitute players got the opportunity to play, which also made the coaching staff have a greater grasp of the choice of the Olympic list. After 9 matches, the six main players of China women’s volleyball team returned to the team. In the following 6 matches, the China team won a total victory even against Italian, Russian and American teams. Zhu Ting, Yuan Xinyue, Gong Xiangyu, Ding Xia and other main players are in a stable state, which also makes fans have more expectations for the upcoming Olympic journey of China women’s volleyball team.

Playing: After waiting for five years, we are ready.

According to the rules, the 12 women’s volleyball teams participating in the Tokyo Olympic Games were divided into two groups, with 6 teams in each group playing 5 round robin matches. The top four teams in the group entered the quarterfinals, and finally decided the champion by eliminating the competition system.

In the latest world ranking of women’s volleyball, the United States tops the list, followed by China and Brazil. The fourth to tenth places are Turkey, Japan, Dominica, Russia, Netherlands, Italy and Belgium. At the Tokyo Olympics, China was in Group B with the United States, Russia, Italy, Argentina and Turkey.

On July 25th, China will make its debut at the Tokyo Olympic Games, against the Turkish team. As a European team with rapid rising momentum in recent years, the Turkish team has considerable strength. At the World Women’s Volleyball League which ended last month, China sent a substitute team to play and lost 3-0 to the Turkish team. At the Tokyo Olympic Games, it was not a big problem for the China team to get off to a good start.

On June 20th, 2021, in the preliminaries of the 2021 World Women’s Volleyball League held in Rimini, Italy, China beat the United States 3-0. The picture shows China player Yan Ni (first from left) blocking the ball in the game. Xinhua news agency

For China, the first real test of this Olympic Games is the game against the United States on July 27th. Since the 2008 Beijing Olympic Games, China women’s volleyball team has lost to its opponents in three consecutive Olympic Games. This American team in Tokyo Olympic Games has many excellent players, such as Larson, Bucky, Robinson, Akinradewo and Poulter, and its strength is good. This year’s World Women’s Volleyball League,The United States defeated Brazil 3-1 in the final to win three consecutive championships. Although it lost 3-0 to China in the last game of the preliminary round, the United States, which won 14 consecutive victories at that time, had ensured the qualification, so it did not send its main force to play. In the group competition of Tokyo Olympic Games, it was China who defeated the American team.teamThe first important goal.

China will play Russian, Italian and Argentine teams in the next three group matches. In recent years, the main players of the Italian women’s volleyball team have gradually matured, especially Egnu, who has strong strength, strong explosive force and extremely lethal re-buckle. How to restrain Egnu’s play is a problem that China women’s volleyball team must solve. Russia sent a number of young players to the Olympic Games this time. The absence of famous players such as Kosheleva, Parubetz and Romanova greatly reduced the strength of the team. In the last two games of the group stage, it was believed that China women’s volleyball team would achieve satisfactory results against Russia and Argentina, which ranked 16th in the world.

In addition to the opponents in the group stage, Serbian women’s volleyball team may pose a threat to China women’s volleyball team in the knockout stage. In the 2016 Rio Olympic Games, China women’s volleyball team defeated its opponent in the final, and reached the Olympic champion podium after a lapse of 12 years. During the Tokyo Olympic cycle, the main lineup of Serbian team has not changed much. Boskovich, Ogennovic, mikhailovich, Lasic and S Popovich will all play in the Tokyo Olympic Games. At the same time, Kosic, lazovic and Caric, who have performed well in this year’s World Women’s Volleyball League, have also been successfully selected. As the champion of the 2018 World Championships, Serbian women’s volleyball team will be one of the strong opponents of China women’s volleyball team.

On July 19th, China women’s volleyball team successfully arrived in Tokyo. "I am very excited to come to Tokyo this time. We are ready, because we have waited for five years, and the time is quite long. Finally, we have the opportunity to embark on the journey of the Olympic Games, and the team is in good shape. Our goal is to attack medals and fight one by one. The Olympic Games is different from the usual leagues. Every game is very difficult. We will go all out and hope to play the best level and win glory for our country. " As Lang Ping said, the defending champion China women’s volleyball team is ready!

  Editor’s Note: The integrated protection and restoration project of landscape forest, field, lake, grass and sand ("landscape project") is a landmark project to practice the concept of life community of landscape forest, field, lake and grass. Since the "Thirteenth Five-Year Plan", 44 "landscape projects" have been deployed and implemented in the important ecological barrier areas of "three districts and four belts". In December, 2022, "China Landscape Project" was selected as one of the first ten flagship projects of world ecological restoration by the United Nations. From now on, this edition will publish a series of reports on "Beautiful China Landscape Project" to show the exploration and achievements of integrated protection and restoration in various places.

  "Look, there is a rock sheep on the right!" When the vehicle drove into Helan Mountain, Ge Yihong suddenly shouted. Looking up, three gray rock sheep are drinking leisurely by the stream, and in the distance, Helan Mountain is covered with a layer of green.

  This is Shitanjing Street, Dawukou District, Shizuishan City, Ningxia Hui Autonomous Region, located in the hinterland of Helan Mountain. Ge Yihong, the 60-year-old stationmaster of street sanitation station, lives here all the year round.

  Helan Mountain is an important natural geographical dividing line and an important ecological barrier in northwest China, which is rich in coal and other resources. Since 1950s, large-scale disorderly mining has seriously damaged the mountain landform. In 2018, the pilot project of ecological protection and restoration of lake grass in the landscape forest field at the eastern foot of Helan Mountain in Ningxia was officially launched; In 2021, the comprehensive improvement of the ecological environment of Helan Mountain was jointly recommended by the Ministry of Natural Resources and the World Conservation Union as one of the 10 typical cases of ecological protection and restoration with China characteristics. Today, Ningxia has completed the comprehensive renovation of 214 points inside and outside Helanshan National Nature Reserve, with an area of over 405,000 mu.

  Mine management, shut down and quit coal and gravel enterprises.

  "In the past two years, the effectiveness of governance has gradually emerged. There have been new changes in the former Shikanjing mining area, and many animals that have lived in the mountains for a long time have gone down the mountain." Ge Yigong said, looking out from time to time. "You see, this ‘ Quack chicken ’ How beautiful! " Along the direction of the finger, I saw the stone pheasants with bright fur and round posture strolling in the grass in droves, and in the distance, the golden eagle with wide wingspan was hovering in the sky … …

  Ge Yihong was born, grew up and worked in the mining area. Different from the days when the mountains were quiet and natural and animals swarmed, the Helan Mountain used to be full of people and the sound of mining rumbled.

  Since 1950s, Helan Mountain has entered the stage of large-scale industrial mining. Mining enterprises blossom everywhere, and there are countless informal small coal mines. "At that time, it was also called Shikanjing District. At the most brilliant time, it was inhabited by more than 100,000 people. There were hospitals, shopping malls, schools and restaurants, including Helan Mountain ‘ Baili mining area ’ Known as. " Ge Yihong said.

  However, the large-scale exploitation of mineral resources has seriously damaged the mountain landscape, and some wild animals are on the verge of extinction due to the sharp compression of their habitats. There are about 50 coal enterprises scattered in the Dagugou area of the carboniferous well, including 5 large pits formed by open-pit mining and more than 10 continuous slag hills. Dust all over the sky and sewage cross-flow, which greatly destroyed the natural ecosystem of Helan Mountain.

  "In the past, there were coal washing plants everywhere. Black wastewater flowed in the ditch and the land was dyed black. Private mines cut off the whole mountain, and dug a large pit for quarrying, forming a gully with a depth of 100 meters. " Ge Yihong still remembers the scene of that year. "Red deer and rock sheep have never been seen. Wearing a shirt, it will be dyed black for a while, and residents are afraid to dry clothes outside. "

  With the progress of the central environmental protection inspector, in 2017, Ningxia began to vigorously rectify the ecological environment of Helan Mountain. Rujigou, Shitanjing and other mining areas closed all open-pit coal mines, 83 mining rights were all withdrawn, and 561 "scattered pollution" enterprises in the centralized coal processing zone at the foot of the mountain were also shut down and banned.

  After clearing the mine, cutting the slope and lowering the platform, a vigorous mine management began. "Following the Helan Mountain Clean-up and Renovation Command, everyone rushed to the slag platform piled up by abandoned coal gangue and transported it day and night." As the stationmaster of Shitanjing Street Sanitation Station, Ge Yihong participated in the whole process.

  Coal gangue was piled up into a waste platform with a height of nearly 100 meters by a mine car, and then cut into a "terraced field" in order to reduce the slope and prevent soil erosion. Subsequently, the mountain-high unclaimed slag pile was covered with loess nearly 50 cm thick, which gave the black slag mountain with a layer of "skin" that could retain green vitality. At the same time, "follow the mountain, follow the mountain, follow the mountain", restore the topography according to the shape, and reduce the safety hazards such as landslides and mudslides.

  During the treatment period, the resident population of Shitanjing decreased sharply, and Ge Yihong moved from the hinterland of Helan Mountain to Dawukou District at the foot of the mountain with the coal miners. Nowadays, standing at the top of the Dagugou governance area, new "mountains" have sprung up. "This is smoothing what was left behind ‘ Scar ’ Only by curing the mine can there be room for further greening. " Ge Yihong said.

  Planting trees, building greening projects and implementing ecological restoration.

  On both sides of the 302 provincial highway crossing Helan Mountain, drip irrigation pipes tightly wrap the towering slag platform like fishing nets. "This is to ensure the survival rate of seedlings. From spring to winter, water should be poured at least 10 times." Ge Yihong said. It was spring, and I saw that many bare land had been covered by all kinds of newly planted saplings.

  After the retreat and restoration of Helan Mountain mine, how to effectively plant trees and increase green has become the number one problem in Helan Mountain management.

  To plant trees, we should start with selecting suitable tree species. Since 2018, Shizuishan Ecological Protection Forest Farm has conducted a series of experiments in Helan Mountain through cooperation with Ningxia University and other scientific research institutes, and finally determined Caragana korshinskii, Salix psammophila, Elm, Pinus sylvestris var. mongolica and Robinia pseudoacacia as the main tree species. "Helan Mountain is a stone mountain with thin soil layer and difficult vegetation growth. Moreover, the annual rainfall here is only two or three hundred millimeters, but the evaporation is more than 10 times. Native plants that are cold-resistant, drought-resistant and salt-tolerant are the best choice. " Zhang Tingxie, director of Shizuishan Ecological Protection Forest Farm, said: "‘ Seabuckthorn, Caragana korshinskii and Prunus armeniaca on the top of the mountain wear hats, and two apricots are wrapped around the waist on the hillside ’ This is what we have summed up. "

  Although he has moved out of the mining area, he heard that there is a green restoration project. Ge Yihong returned to Shihanjing, joined the army of tree planting, and got busy in the Dagugou area with the heaviest restoration task.

  Waving steel drill and shovel, struggling to dig hard sand and gravel ground, digging out 80 cm square tree pits, and then righting, ridging, tamping and watering the seedlings. "Dig up the thin soil layer, and here is the coal gangue that can’t store water. If you want trees to survive, you have to cover them with moisture-retaining soil, nutrient soil and sealing soil, step on them layer by layer, and finally mention them slightly to make the roots of seedlings grow in the same direction. " This is known as the "three steps and one mention" trick, and Ge Yihong and the tree planters are well known. "Now, the survival rate of trees can reach 85%." Ge Yihong said.

  Planting trees in spring and autumn, watering in summer, controlling pests and diseases, and conducting fire inspections in winter, Ge Yihong "soaks" in Helan Mountain all year round. Nowadays, driving around the mountain along the ecological restoration area of Helan Mountain, you can see "green-planting people" digging holes to change soil, placing saplings and lifting water to irrigate … … "The apricot at the foot of the mountain was planted by us a few years ago. When the apricot blossoms are in full bloom, they are layered. This year, we intend to put this cinder mountain in green. " Zhang Tingxie said.

  Systematic improvement of governance results, integrated development of ecological culture and tourism.

  "Now there are less than 100 people left in Shitanjing Street. After the restoration of Helan Mountain is completed, my life will be idle." Ge Yihong, who returned to the Shitanjing, did not go down the mountain and stayed in the old mining area. However, it was not long before the days of "long years in the mountains", the Shitanjing became lively again.

  Since autumn and winter of 2021, Shizuishan City has mobilized 105 units, including party and government organs, enterprises and institutions, and units stationed in stone areas, to carry out greening activities in eight mine ecological environment management areas in Dalanggou District, Shitanjing Street, Helan Mountain along the 302 provincial highway. At present, it is the planting period, and many staff members are busy setting out, waving picks and shovels, and leveling the ground.

  "Through ‘ Green Planting in Pieces in Helan Mountain ’ Activities can plant 12,000 mu of trees a year. " Jia Zengjun, director of the Natural Resources Bureau of Shizuishan City, said: "More importantly, the task of slicing and planting has stimulated everyone’s enthusiasm and made everyone feel that the results of Helan Mountain governance are hard-won. Now the afforestation task is about to be completed. From the closure and rectification of the mining area to the ecological restoration of internal and external integration, and then to the improvement of the governance results system, Helan Mountain is being dressed in green. "

  Ecological improvement has made Helan Mountain, which once sold coal, have the possibility of diversified development.

  At 7: 35 every morning, the 7524 train leaves Yinchuan for Rujigou. This small train is called "Shitanjing Tourist", which connects in series with the former coal mining areas such as Dagugou, Baijigou and Rujigou. A 3-hour and 52-minute drive takes passengers deep into the hinterland of Helan Mountain to visit the passionate industrial years.

  "Eco-tourism+industrial film and television shooting base" is a new way explored in Shitanjing mining area. Since 2017, some old houses in Shitanjing have been repaired and old streets and alleys have been protected. After the establishment of the Shitanjing Industrial Tourism Town Exhibition Hall, Ge Yihong was hired as a commentator to receive visitors: "I didn’t expect the industrial relics left in the old mining area to become a unique advantage in developing tourism. In the past few days, I have received thousands of tourists, and many movies have come here to take pictures!"

  After several years of management, the ecological function of Helan Mountain has been steadily improved, and the goals of ecological corridor restoration and biodiversity improvement are gradually being implemented. This towering mountain range is witnessing the ecological vision of "green water and green mountains" becoming a beautiful life within reach.

The Secret of "Bird’s Nest" Fireworks (I): Let’s see how peony blooms.


  On August 8, the 29th Summer Olympic Games opened at the Beijing National Stadium, and gorgeous fireworks reflected the night sky in Beijing. China News Agency issued Wang Dongming photo


  China News Service, August 8 th: The Secret of the "Bird’s Nest" Fireworks (I): Look at how the peony blooms.


  China News Service reporter Wu Qingcai


  At the opening ceremony of the Beijing Olympic Games tonight, red peonies are in full bloom over the "Bird’s Nest", and there are many strange shapes such as the Olympic rings and the dove of peace. So, how on earth are the peonies blooming over the Bird’s Nest?


  Zhao Weiping, the commander-in-chief of the "Bird’s Nest" and the Great Wall fireworks display team at the opening and closing ceremonies of the Beijing Olympic Games, revealed to our reporter the secrets of the seven classic shapes of fireworks that night.


  The First Classic Modeling-How Peony Blooms


  The first climax of the "Bird’s Nest" is to interpret the whole process of peony, the national flower, from budding to blooming, and suddenly the Bird’s Nest turns into a red ocean of peony. From the blossoming of flowers and bones to the "relay" opening of petals, and then to the blooming of peony, the blooming process of "peony blossom" took only eleven seconds, but the number of fireworks was 4,845.


  Zhao Weiping, chairman of the national brand Panda Fireworks Company, said that in order to make the whole red peony cover the whole bird’s nest, the "Peony Blossom" was set off all the steel frames at the top of the bird’s nest and the upper edge of the bowl of the bird’s nest. In order to choose the right color and fully show the elegance and wealth of peony, the designers of Panda Fireworks screened dozens of schemes and finally chose a peach red.


  Using the three-dimensional special effects of the computer, the designer drew a huge peony covering the roof of the "Bird’s Nest", and then selected 85 points on the roof of the "Bird’s Nest", each of which was responsible for emitting three petals, each of which was composed of 29 fireworks, symbolizing the 29th Olympic Games.


  "Eighty-five points have different inclination angles, so as to draw a peony flower that is natural." Zhao Weiping said that when setting off, the "flower heart" was emitted from the inside to the outside, and then the innermost "petal" was emitted, which in turn went over to the outermost petal. When the last petal was opened, 85 points were started at the same time, and fireworks were fired in unison, forming a big peony with bright red and unrestrained enthusiasm.


  The Second Classic Modeling ―― Turning out the "Olympic Five Rings"


  That night, five circles of five colors, red, yellow, green, black and basket, appeared in the sky, and the five circles were connected with each other, showing the Olympic rings pattern.


  "Playing the Olympic rings pattern, some Olympic host cities also had this idea, but it didn’t work out." Zhao Weiping told reporters: The biggest difficulty in displaying the Olympic rings and other patterns with fireworks is that the initiation point and time interval of fireworks are difficult to control. The interval error of each fireworks is less than 0.03 seconds, and the audience can see the circle and the five rings only when they are fired in series at a constant speed. Finally, under the guarantee of new scientific research technologies such as air launch and chip fireworks, the global problem of depicting the Olympic rings with fireworks was completely solved by China fireworks people.


  The Third Classic Modeling ―― "Silver Waterfall" Flows into the Stand


  During the opening ceremony, there was a "silver waterfall" nearly 40 meters long, like the Milky Way, which slowly hung down along the bowl of the "Bird’s Nest" and flowed into the stadium. The "Bird’s Nest" stand immediately turned into a silver hall. Fireworks exploded around, but the audience couldn’t smell a trace of sulfur, and there was no worry about sparks.


  Zhao Weiping said that the diameter of the bowl of the "Bird’s Nest" is about 500 meters, which is more than 40 meters above the ground. This shape requires that the diameter of the "Silver Waterfall" should not be less than 500 meters and the length should not be less than 30 meters, otherwise, the audience will not be able to be there. In order to realize this idea, Panda Fireworks Man has broken through four major problems: environmental protection, safety, tasteless, discharge, quick installation and quick disassembly.


  The Fourth Classic Modeling ―― "Dove of Peace" Bird’s Nest "Spreading Wings"


  Careful viewers will find that a pair of snow-white wings were born on both sides of the "Bird’s Nest", flapping up and down, just like a dove spreading its wings and flying.


  Zhao Weiping told reporters that it is not difficult for the "Bird’s Nest" to give birth to "wings". What is difficult is that the wings should be flapped up and down, showing a dove of peace spreading its wings and flying dynamically. In order to make this dove of peace "smart", the researchers first improved the discharge effect of the traditional fireworks element "white tail", which has only white light and no track left by the tail passing through the air, just like the wings of the dove of peace. In order to make the wings move, the researchers calculated the flapping frequency of the flying dove of peace, so that the "Bird’s Nest dove of peace" fluttered its wings once a second on average.


  The Fifth Classic Modeling ―― Dynamic World of "Red Flash Bird’s Nest"


  Its modeling features are as follows: a red silk thread runs through the "Bird’s Nest" as red neon lights keep flashing, and under its embellishment, the whole "Bird’s Nest"


  "In the flashing, running, jumping.


  Zhao Weiping said that the first difficulty of the "Red Flash Bird’s Nest" lies in the layout. In order to cover the entire "Bird’s Nest", a launching point should be set up every five meters on each main beam; At the junction of the two main beams, a launching point is also set up every five meters, and all launching points are evenly distributed, so that the whole "Bird’s Nest" can jump in the red ocean; The second difficulty lies in the time difference control, and the fireworks at each point must be lit and extinguished at the same time.


  The Sixth Classic Modeling ―― "Opening the Tianmen"


  Its modeling features are: a resplendent arched gate, which appears over the "Bird’s Nest". From closing the door and opening a crack to opening half and three quarters until the Golden Gate finally opens.


  Zhao Weiping said, "Opening the Tianmen Gate" is difficult to measure in the distance and angle between the ground and air. The distance between the first group of emission points and the angle with the horizontal plane must ensure that the emitted fireworks meet in the air and hand over an arch shape; The distance and horizontal angle between the second group of fireworks must ensure that when the fireworks meet in the air, there is just a gap, just like the door has just opened a gap, and so on, until the Golden Gate opens, the angle is a little off, so the process of opening the door cannot be vividly reproduced.  


  The Seventh Classic Modeling-"Countdown" Entering "Olympic Time and Space"


  9, 8, 7 … At the opening ceremony of the Olympic Games, the first thing that appeared in the air was flashing numbers, which sent a strong signal in fireworks language: the Olympic Games is near! Zhao Weiping introduced that the number nine drawn with fireworks stays in the air for no less than one second. As soon as the number nine goes out, it lights up at eight and flashes again for one second. "If any number stays even in the blink of an eye, the fireworks will not draw a countdown stopwatch, which is synchronized with the stopwatch and does not allow any error.".
