Having moved into China’s space home for nearly three months, the Shenzhou-14 crew smoothly conducted its first extravehicular(舱外的) activity on Thursday, the China Manned Space Agency (CMSA) said. The entire process took about six hours, and it was the first time that astronauts ventured out through the airlock cabin(气闸舱) in the Wentian lab module(舱), which just arrived at the space station about a month ago.

Mission commander of Shenzhou-14 Chen Dong and crew member Liu Yang were assigned to conduct the spacewalk mission this time, while their teammate Cai Xuzhe was responsible for various support work inside the cabin. They began preparing for their exit wearing spacesuits at 3:48 pm on Thursday, and at 7 pm, the two successfully moved out of the cabin. Together, Chen and Liu completed the installation of the extended pump set of the Wentian and the lifting of the panoramic(全景的) camera, as well as other tasks with the help of the small robotic arm.

Unlike previous times when the Shenzhou-12 and -13 crews exited the space station through the Tianhe core cabin, the Shenzhou-14 crew for the first time ventured out through the airlock cabin in the Wentian lab module, which just arrived at the space station on July 25. The node cabin(节点舱) for the astronauts’ exit in the Tianhe has a gate width of 85 centimeters, while the airlock cabin in the Wentian is one meter wide, allowing astronauts with space suits on and equipment in hand to walk more “freely” into space. Therefore, the airlock cabin of the Wentian will become the main exit-entry point for extravehicular activities, while the previous one in the Tianhe will serve as backup(备用物). The two exit-entry cabins will better ensure the safety of astronauts in case of an emergency during extravehicular work.

_____________________ The first team of astronauts entering the Tianhe, the Shenzhou-12 crew, carried out one spacewalk mission, while for the Shenzhou-13 crew, two missions were successfully completed. The Shenzhou-14 crew is expected to conduct two to three spacewalk missions.

1.Who does the underlined phrase “the two” refer to?

A Chen Dong and Liu Yang.

B Cai Xuzhe and Liu Yang.

C Wang Yaping and Liu Yang.

D Cai Xuzhe and Chen Dong.

解析：选A。A词意指代题。根据第二段第一句“Mission commander of Shenzhou-14 Chen Dong and crew member Liu Yang were assigned to conduct the spacewalk mission this time”和第三句“Together, Chen and Liu completed the installation of the extended pump set of the Wentian”可知，开展舱外操作的是陈冬和刘洋，即“the two”指的是陈冬和刘洋。故选A。

2.Which makes it more convenient for astronauts to walk into space?

A The smaller equipment.

B The cabin in the Tianhe.

C The lighter spacesuits.

D The cabin in the Wentian.

解析：选D。D细节理解题。根据第三段尤其是第二句可知，神舟十二号、十三号的航天员是从天和核心舱的节点舱（85厘米）出舱的，而本次神舟十四号航天员改为从问天实验舱的气阀舱（1米）出舱的，航天员此次出舱的地方能让他们进出更“自由”。故选D。

3.What can be put back into the blank?

A Exiting from the Wentian lab module means the astronauts must take different routes.

B Compared with previous times, Shenzhou-14’s extravehicular activities are more task-oriented.

C China has been making steady progress in planning extravehicular activities.

D Chinese people have much knowledge of spacewalk missions these years.

解析：选C。C 推理判断题。根据题空后面的内容可知，中国航天事业稳步发展。故选C。

4.In which part of a newspaper can we read the passage?

A AIR & SPACE.

B FOOD & HEALTH.

C SCIENCE & EDUCATION.

D SPORTS & FASHION.

解析：选A。A 推理判断题。本文描述了神舟十四号乘组圆满完成首次出舱任务，与航天相关。故选A。
