Students attend a science lesson given by astronauts on board China’s Tiangong space station on Wednesday, March 23, 2022. Zhai Zhigang, Wang Yaping and Ye Guangfu, the members of the Shenzhou XIII, which was launched ( 发射 ) on October 16, appear on television screens watched by millions of students across China.

During the 41-minute lesson, the astronauts did four experiments to show physical phenomena( 现象 ) only possible in a weightless environment, such as “liquid crystallization” and “a water bridge”. In one experiment, Wang used a toy of Bing Dwen Dwen, the mascot of the 2022 Beijing Winter Olympic Games, to show how objects fly in Tiangong. They invited the young viewers to do similar experiments to see the differences between space and land environments.

Before closing the lesson, the astronauts answered questions from students. The questions covered the life and work in space, such as how to take care of the skin and whether hot water was available.

Wednesday’s event marked the third time Wang had taken part in a space lesson. In June 2013, she gave the nation’s first space lesson to over 60 million Chinese students in Shenzhou X. It made China the second country, following the United States, to have given a lesson to schoolchildren from space.

In early December, Wang gave the country’s second space lesson from the Tiangong station. The astronauts showed viewers how they lived and worked inside the space station.

“These science lessons can encourage students to explore the world of science and technology.” Shi Yi, a physics teacher, said after today’s activity, “Encouraged by China’s spaceflight achievements, my school has built a space science laboratory and the teachers give lessons about space exploration.”

C ． The Exploration of Outer Space. D ． The Development of Tiangong Space Station.

25 ． What kind of writing is the passage?

A ． A science novel. B ． A news report. C ． A fairy tale. D ． An interview.

答案

D    22 ． C    23 ． D    24 ． A    25 ． B

【导语】本文主要介绍了中国天宫空间站宇航员给学生上的一次在线课程，宇航员进行了四项实验来给学生展示宇宙飞船中的物理现象。

21 ．细节理解题。根据 “During the 41-minute lesson...such as “liquid crystallization” and “a water bridge”.” ， “They invited the young viewers to do similar experiments to see the differences between space and land environments.” 和 “Before closing the lesson, the astronauts answered questions from students.” 可知，在 2022 年 3 月 23 日，宇航员做了水桥实验，回答了学生的提问和邀请学生做实验，没做的是展示他们如何在空间站里生活。故选 D 。

22 ．推理判断题。根据 “March 23, 2022” 和 “In early December, Wang gave the country’s second space lesson from the Tiangong station.” 可知，在 2021 年 12 月，王亚平在太空做了第二场讲座，故选 C 。

23 ．推理判断题。分析四个选项可知， ABC 三项都在陈述客观事实，选项 D“ 宇航员做的三个科学实验是有意义的 ” 是观点而非事实，故选 D 。

24 ．最佳标题题。本文主要介绍了中国天宫空间站宇航员给学生上的一次在线课程，宇航员进行了四项实验来给学生展示宇宙飞船中的物理现象。故选 A“ 宇航员在太空上课 ” 符合主题，故选 A 。

25 ．推理判断题。本文介绍中国天宫空间站宇航员给学生上的一次在线课程，宇航员进行了四项实验来给学生展示宇宙飞船中的物理现象。推测可能在新闻报道上看到这篇文章，故选 B 。
