Yidong, the manderinchief and chief designer of the spacecraft application system of China’s manned space program, explained to the media on September 23. Earlier on September 23, several news portal websites reported that a Shenzhou VII astronaut would spacewalk at 16:30 – the day after launch. They said if Shenzhou VII was launched at 21:10 on September 25, the astronaut would leave the capsule at 16:30 on September 26. However, Gu corrected the reports, explaining that the spacewalk would begin on the day after orbit is achieved. If the launch was on September 25, the spacecraft would enter orbit on 26, and the astronaut would spacewalk on the afternoon of 27. Experts said the spacecraft would climb to an altitude of 300 km and then into outer space. Though the astronaut would be protected by the special seat and garment, he would need a certain period of time to adjust to the environment. He might experience nausea, vomiting or other disfort if he left the capsule too early. Six astronauts – the three confirmed Shenzhou VII team members Zhai Zhigang, Liu Boming, and Jing Haipeng, plus their backups – moved to the Jiuquan Satellite Launch Center in northwestern China’s Gansu Province on September 21. One of the three astronauts onboard Shenzhou VII will step out of the capsule and conduct a historic space walk that will be telecast live. 熱點3:“鳥巢”介紹 建筑面積:258,000平方米。 座席數(shù):91,000 賽后功能:體育比賽和文化、娛樂活動中心 完工時間:2020年底 熱點5:體育鍛煉的重要性 據(jù)報道,我國年輕人,特別是大學(xué)生的健康狀況不容樂觀。 [寫作導(dǎo)航]先從所給提示“我國年輕人,特別是大學(xué)生的健康狀況不容樂觀”入手,引入主題:造成這一結(jié)果的原因是忽視體育鍛煉;第二段詳細(xì)列舉體育鍛煉的重要性,如加速血液循環(huán)、增進新陳代謝、消耗多余脂肪、促進睡眠等;最后一段總結(jié)體育鍛煉的好處,呼吁人們積極參加鍛煉。The Importance of Physical Exercises It is reported that the health of young people in China, college students in particular, is not as good as is supposed to be.
