Are there any competitions in the track and field final on the night of the 21st that Chinese athlet

Clothes printed with "I love China" must definitely be worn Although Liu Xiang is no longer competing, we must let all people in the world know our patriotic spirit.

It's not because of someone's withdrawal

It's a good idea to bring binoculars

If you are looking at the medals, no. Athletics in the evening. China has little hope of hitting the medals. If it's to watch the competition of Chinese athletes. The men's level 3 long jump final has China. Shi Dongpeng in the 110m hurdles is also likely to reach the final.

The national track and field team is not a professional team at the provincial and municipal level. When there is no competition task, all team members return to the professional team of their province and city for training. In the event of an international competition, the General Administration of Sports of China will form a national team a few months before the competition, which is theoretically a temporary national team.

Athletes who are at their peak are selected to participate in the national training team. Then the winning rate is finalized, and the country is represented in the competition abroad. This saves the National Sports Agency a large part of the necessary expenses during the day-to-day training period when there are no competition tasks.

This approach is currently used by national teams in many sports.

If you wish to get the women's list of the national track and field team. Please provide me with the specific information about the event. I'll keep you answered.

Ma Jiajun In April 1993, "Ma Jiajun" collectively set a new national record for women's marathon in Tianjin; In August, she won all three gold medals in the women's 1500m, 3000m and 10000m at the World Championships in Stuttgart; broke the world record in the Seventh Games in September; In October, she won the women's individual and team championships in the World Cup marathon in Spain. The first generation of "Ma Jiajun" is almost all world-class masters, Wang Junxia, Qu Yunxia, and Liu Dong have proud world records. At that time, Lao Ma had a famous saying:

The lock (said) will be broken, and the lock (said) will be broken (let) whoever breaks it.

It's a pity that the good times are not good, "Ma Jiajun" was torn apart due to the departure of the team, and Wang Junxia, who won the gold medal at the Atlanta Olympics, has no chance with Ma Junren. In 1997, the second-generation "Ma Jiajun" showed his majesty again in the Eighth National Games, but it was short-lived. The second generation of "Ma Jiajun" is led by Mei Bo, although she also broke the 5000m world record, but she failed to make up for the lack of qi in "Ma Jiajun", and she soon became a flower of tomorrow.

At present, this batch of "Ma Jiajun" has not only broken the world record, but has not even won the world championship. The proudest player is Dong Yanmei, who has won 1 gold medal for the time being. The brilliance of the third generation of "Ma Jiajun" is limited to the achievements in China, which is currently unmatched.

At present, although the talent of this group of players is not as good as the first two batches of senior sisters, the progress is quite obvious. Lan Lixin, the main team member, won the championship in last year's City Games with 4:11.62. In June this year, in Jinzhou, the time was improved to 4:03.95; The leader Dong Yanmei clocked 15:51.16 in the 5,000m at the National Championships last October, and 15:03.99 in this year's Jinzhou Finals.

The main targets of the third-generation "Ma Jiajun" in this Olympic Games are 1500m and 5000m, and the main opponent is Romania's "double king" Sabo.

The Olympic gold medal in the 1500m is expected to be around 3 minutes and 55 seconds. Saab's best time was 3:56.97, while Li Jingnan's best time in "Ma Jiajun" was 4:04.84. If you take into account her recent injury, she is expected to improve at the Olympics and should compete with Saab.

Dong Yanmei's 5000m opponents are Saab, Morocco's Oziz, Germany's Mikitenk, Britain's Radlife and Ethiopia's Wokku, all of whom are not low. Dong Yanmei's best time was more than half a point worse than Sabo's 14:31.48.

Born in Jinan, Zheng Fengrong showed a talent for high jump at a very young age and was selected for the national track and field team in 1953. From the moment she joined the team, she was determined to break the world record in athletics. In order to achieve this goal, which the Chinese have never achieved, she is almost desperately training.

In 1956, Zheng Fengrong's training load reached 309 times a year, and until now, there are only a handful of athletes in the world who can achieve this ultra-high intensity. Once in Shanghai, it rained when Zheng Fengrong practiced the pole, and the whole team ran indoors. The coach asked Zheng Fengrong if he also went indoors?

She said, no, what if it rains at the time of the international competition? So keep practicing.

In 1958, the IAAF awarded a medal to a Chinese female high jumper. The winner of this medal is Zheng Fengrong.

Xing Huina entered Weifang Sports School in 1996, and the coach was Chi Yuzhai; In 1999, he entered Shandong Institute of Sports Technology, and the coach was Yin Yanqin; In January 2003, he was selected into the national training team, and the coach was Wang Dexian.

Key achievements: 2001 Runner-up in the 5000m at the Ninth National Games.

2002 Busan Asian Games women's 10,000m third.

In 2003, the women's 10,000m champion, 5,000m champion and 1,500m runner-up in the 5th City Games.

2003 Seventh in the 10,000m at the World Athletics Championships.

Main record: 2003 Paris World Athletics Championships Women's 10,000m World Junior Record 30:31

Zheng Fengrong Zheng Fengrong was born on March 2, 1937 in Jinan, Shandong Province, and has loved track and field since childhood. In 1953, she represented Shandong Province in the 1st East China Athletics Games, and won the long jump championship and the high jump runner-up. In 1953, he was selected into the national track and field training team for special training in high jump.

In 1954, at the national track and field games for college and middle school students in 13 cities, she broke the national record in the women's high jump with a score of meters. During her studies at the ** Institute of Physical Education (the predecessor of the current Beijing Sport University), her high jump score improved from meter to meter. On August 18, 1957, at the Berlin International Athletics Championships, Zheng Fengrong won the championship with meters, and since then she has crossed the ranks of the world's women's high jump.

From October to November of the same year, she jumped the meters, meters, and meters successively, and crossed the meter bar on November 17, breaking the women's high jump world record held by American athlete Mock Daniel.

Only B can be selected.

In reality, Liu Xiang's height in ** = h h, this ratio is the reduction ratio of **.

l multiplied by this ratio is the displacement of Liu Xiang in 1 60 seconds in reality.

That is to say, in the time of 1 60 seconds, Liu Xiang's displacement is l*h h, so Liu Xiang's speed in 1 60 seconds of sprinting is 60*l*h ha, c, d need to know how many seconds Liu Xiang ran, and it is not given in the question.

By the way, that photographer filmed athletes sprinting with an aperture of 16 and a speed of 1 60s, which was also too amateurish.

A: Option B is correct.

When crossing the line, the ** time is extremely short, and the average velocity obtained from this can be regarded as the instantaneous speed when crossing the line.

The width of the fuzzy part of the bib is l times h h, which is the displacement in **time 1 60s.

Crossing speed = width of the blurred part of the bib number is lx(h h) **Time = 60lh h
