Question

【题目】

China's second female astronaut, Wang Yaping, has given the country's first-ever video lecture from space. The whole lecture lasted about 40 minutes.

Speaking to students through live video, from the Tiangong-I space laboratory, Ms. Wang used spinning tops (旋转的陀螺), a ball and some water to explain physics in zero-gravity(失重), with the help of a fellow astronaut.

Ms. Wang used different experiments to demonstrate the concepts of weight and mass (重量和质量的概念) in space. Towards the end of the class, Ms. Wang made a film(薄膜) of water using a metal ring. She then turned the film of water into a water ball by pouring more water onto it.

Around 330 primary and secondary school students watched the lecture from a special classroom in Beijing, where they could also ask Ms. Wang questions through live video. From time to time, the students greeted her lecture with warm applause(掌声).

When answering a student's question, Ms. Wang described what she could see in space. "The stars we see are much brighter, but they do not twinkle(闪烁)," she said, "The sky we see isn't blue, but black. And every day, we can see the sun rise 16 times because we circle the Earth every 90 minutes."

About 60 million students and teachers around China also watched the lecture live on TV.

A.To explain physics of zero-gravity in space.

B.To demonstrate the concept of weight and mass in space.

C.To tell us what can be seen in space.

Answer 1

【答案】

【1】A

【2】D

【3】C

【4】D

【5】B

【解析】

本文讲述了中国第二名女宇航员王亚平在太空发表了中国首次视频演讲。这个演讲的目的是解释物理失重。

【1】推理判断题。根据Speaking to students through live video, from the Tiangong-I space laboratory, Ms. Wang used spinning tops (旋转的陀螺), a ball and some water to explain physics in zero-gravity(失重), with the help of a fellow astronaut.可知，这个太空演讲的目的是解释物理失重，故选A。

【2】词义猜测题。根据Ms. Wang made a film(薄膜) of water using a metal ring.可知，王女士用一个金属环制作了一个水膜，这是在做演示，故选D。

【3】细节理解题。根据She then turned the film of water into a water ball by pouring more water onto it.可知，在演讲结束的时候，王亚平把水膜变成了一个水球，故选C。

【4】细节理解题。根据About 60 million students and teachers around China also watched the lecture live on TV.可知，在中国各地，大约有6千万名学生和老师在电视上观看这个演讲的直播。

故选D。

【5】推理判断题。根据Speaking to students through live video, from the Tiangong-I space laboratory, Ms. Wang used spinning tops (旋转的陀螺), a ball and some water to explain physics in zero-gravity(失重), with the help of a fellow astronaut.可知，王亚平在一个宇航员的帮助下完成的，因此不是她独自完成的，故B项与原文不符，故选B。

认真阅读题干，根据题干要求，在文中寻找答案所在的语句或段落，进行分析理解，词义猜测，推理判断和概括归纳，选出正确的选项。例如小题3，根据She then turned the film of water into a water ball by pouring more water onto it.可知，在演讲结束的时候，王亚平把水膜变成了一个水球，故选C。
