問題詳情:
China launched the Shenzhou XI manned spacecraft on Monday morning to transport two astronauts to the Tiangong II space laboratory.
The spacecraft was sent skyward at 7:30 a.m. atop a Long March 2F rocket from the Jiuquan Satellite Launch Center in Northwest China. It is carrying two male astronauts—49yearold Jing Haipeng and 37yearold Chen Dong.
After the launch, the spacecraft will travel two days before docking with the Tiangong II, which was lifted from the Jiuquan Center in midSeptember. Then the astronauts will enter the space lab and stay there for 30 days, which will be the longest space stay by Chinese astronauts.
The core tasks of the Shenzhou XI mission are to test rendezvous(匯合,相會) and docking technologies for the country's planned space station, to verify the lifesupport capability of the spacecraftspace lab combination as well as conduct scientific research and test engineering experiments, according to Wu Ping, deputy director of the China Manned Space Agency.
Prior to the Shenzhou XI, China had sent five spacecraft and 10 astronauts to space since 2003, when it lifted the Shenzhou V to carry the nation's first astronaut Yang Liwei, who is now a senior space official, into space.
China is the third country in the world that has independently fulfilled manned spaceflight following the former Soviet Union and the United States.
China's manned space program, a source of national pride, aims to place a permanent manned space station, which will consist of three parts—a core module attached to two labs, each weighing about 20 metric(度量的) tons—into service around 2022, according to the manned space agency.
26. What does the underlined word “docking” in the third paragraph mean?
A. Join together. B. Cut short. C. Take away. D. Cut back on.
27. How long will the two astronauts stay in space after the launch?
A. Five weeks. B. One month. C. Thirtytwo days. D. Four weeks.
28. According to Wu Ping, all the following are the tasks of the Shenzhou XI mission EXCEPT ________.
A. to test rendezvous and docking technologies
B. to verify the lifesupport capability of the spacecraftspace lab combination
C. to conduct scientific research and test engineering experiments
D. to place a permanent manned space station
29. What might be the best title for the text?
A. China Launches Manned Spacecraft B. The Core Tasks of the Shenzhou XI Mission
C. The Tasks of Chinese Astronauts D. China's Manned Space Program
