Question

【题目】

The world’s largest radio telescope was finished on Sept. 25, 2017 in China.

FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius（半径范围） and only one county center within 25 kilometers.

FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信号).

The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(银河系) and explore the origins（起源）of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.

【1】Where was FAST developed?

A. In China.B. In Russia.C. In America.

【2】The underlined word "giant" probably means "___________" in Chinese.

A. 神秘的B. 巨大的C. 宽广的

【3】FAST is used to __________________.

A. explore the origins of human beings

B. receive distant radio messages from the universe

C. watch the beautiful scenery of the Galaxy

【4】From the passage, we can know that __________________.

A. FAST is the largest radio telescope all over the world so far

B. Noisy towns are around the telescope within a 5-kilometer radius

C. The second-largest radio telescope is made up of 4,450 panels

【5】How long did it take to finish the FAST project?

A. About twenty years.B. About ten years.C. About six years.

【解析】

这篇短文主要讲述了世界上最大的射电望远镜在中国建成。

【1】细节理解。根据文中FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province.可知，在中国。故选A。

【2】根据上文FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province.及下文is built on a howl-like valley.可知上文是说这个巨大的盘子被建在山谷上。故选B。

【3】根据文中The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe可知，被用来接收来自宇宙的远程无线电信息。故选B。

【4】推理判断。根据文中FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia.可知，Fast是迄今为止世界上最大的射电望远镜，选项A是正确的。故选A。

【5】推理判断。根据文中The FAST project began in 2011及The world’s largest radio telescope was finished on Sept. 25, 2017 in China.可知，大约花费6年的时间。故选C。
