China launched its second space laboratory, the Tiangong II, on Sept 15, which space officials say will become the country’s largest scientific platform in space to date.

The space lab was lifted off atop a Long March 2F carrier rocket from the Jiuquan Satellite Launch Center in Gansu province at 10:04 pm. Around 20 minutes later, the mission was declared a success.

The Tiangong II did preparations in space for about one month and then the Shenzhou XI manned spacecraft rocketed two astronauts to the lab on October 17th. The pair will make it their home for 30 days before being returned to Earth.

The lab’s predecessor, Tiangong I, was launched in September 2011 and was used mainly to test technology involved in space docking.

By comparison, the Tiangong II will be used to conduct more than 40 scientific and technological experiments together with the Shenzhou XI. That’s many times more than those carried out by the Tiangong I and the three previous Shenzhou spacecraft, according to Wu Ping, deputy director of the China Manned Space Agency. China’s manned space program has entered a “new phase of application and development,” he said.

试题分析：本文介绍2016年9月15日，中国成功发射了第二个空间实验室——天宫二号。相关工作人员称，它将成为中国迄今为止规模最大的空间科研平台。中国的载人航天事业已经进入了一个应用发展的新阶段

【1】C 词义猜测题。根据第二段第一句The space lab was lifted off atop a Long March 2F carrier rocket from the Jiuquan Satellite Launch Center in Gansu province at 10:04 pm.（当晚10点04分，搭载天宫二号的长征二号F运载火箭在甘肃省酒泉卫星发射中心发射升空。）可知，atop意为“在…上边，在…上方”，这里表示天宫二号在长征二号F运载火箭的最上面，故选C。

【2】A 推理判断题。根据最后一段中By comparison, the Tiangong II will be used to conduct more than 40 scientific and technological experiments together with the Shenzhou XI. (相比之下，天宫二号将会和神舟十一号一起，开展40多项科技实验。)China’s manned space program has entered a “new phase of application and development(中国的载人航天事业已经进入了一个应用发展的新阶段。)可推知，作者对天宫二号是持乐观的态度。

【3】C 细节理解题。根据最后一段中That’s many times more than those carried out by the Tiangong I and the three previous Shenzhou spacecraft, according to Wu Ping, deputy director of the China Manned Space Agency.据中国载人航天工程办公室副主任武平介绍，天宫二号和神舟十一号承担的实验任务，要比天宫一号和先前三代神舟火箭多得多，但不一定比后面的太空实验室多，故C项错误。
