贺！神舟十二号载人飞船发射成功！

The Shenzhou-12 manned spaceship is launched at 9:22 am Thursday (Beijing Time) from the Jiuquan Satellite Launch Center in northwest China.

Shenzhou XII, which is carrying three astronauts—Nie Haisheng, Liu Boming and Tang Hongbo, is set to rendezvous (会合) and then dock with (对接) the core module, named Tianhe, or Harmony of Heavens, in a matter of hours. Then the crew will float into the module and start their three-month mission inside the craft, the first, and central, section of China’s space station, named Tiangong, or Heavenly Palace.

During this mission, astronauts are scheduled to conduct two extravehicular (舱外的) operations, popularly known as spacewalks, to use mechanical arms to install equipment and check Tianhe’s external condition.

Their work will enable the China Manned Space Agency to accumulate experience and check the capability, performance and compatibility of systems involved in the space station program to prepare for the next steps in its construction, said Ji Qiming, the agency’s assistant director.

In 2022, two large space labs will be launched to connect with the core module. Moreover, two manned missions and two robotic cargo flights will be made that year to continue construction of the Tiangong station, which is scheduled to become complete and start formal operation around the end of 2022.

Upon its completion, Tiangong will be manned regularly by groups of three astronauts in periods lasting several months. During handovers (移交) to new three-astronaut groups, the station will accommodate up to six astronauts.

1.How long will the three astronauts stay in space?

A For several hours.

B For three months.

C For several years.

D Until 2022.

解析：选B。B细节理解题。根据第二段Then the crew will float into the module and start their three-month mission inside the craft...这三位航天员将进入核心舱，开启为期三个月的任务执行……可知三位航天员将在太空停留三个月。故选B。

2.Which belongs to the purpose of astronauts’ spacewalks?

A Accumulating experience.

B Improving Tianhe’s external condition.

C Conducting two extravehicular operations.

D Using mechanical arms to install equipment.

解析：选D。D细节理解题。根据第三段可知，extravehicular (舱外的) operations也就是spacewalks，航天员进行太空行走的目的是use mechanical arms to install equipment和check Tianhe’s external condition，D项符合。故选D。

3.What can we infer from Paragraph 5?

A Two large space labs will be launched in 2022.

B The construction of Tiangong station isn’t finished.

C There will be two robotic cargo flights.

D The Tiangong station is under formal operation.

解析：选B。B推理判断题。根据倒数第二段可知，两个大型空间站将被发射，还将进行两次两次货运飞船任务，空间站预计在2022年底建成且开始正式运行。A和C为原文，非推断；D项错误。故选B。

4.Which of the following is NOT true according to the passage?

A Shenzhou XII will meet Tianhe in a matter of hours.

B Astronauts are scheduled to conduct spacewalks.

C Astronauts’ work will help to gather experience.

D The station can hold over six astronauts.

解析：选D。D细节理解题。根据During handovers to new three-astronaut groups, the station will accommodate up to six astronauts.可知空间站最多可以容纳6名宇航员，故D项错误，故选D。
