“如果这口锅里装满了饭,够全世界的人吃上好几天。”你知道这口“锅”指的是什么吗?
What looks like a huge pan(平底锅) in Guizhou, but can see faraway stars in space? The answer is China’s Five-hundred-metre Aperture Spherical radio Telescope (FAST)(500米口径球面射电望远镜).
1.
Known as the "Sky Eye", FAST is the world's largest radio telescope. It's so big that it covers an area as large as 30 soccer fields(足球场)! People started building it in 2011 and finished in 2016.
2.
Guizhou is far away from cities, and not many people live there. So devices from human activities, such as TVs, mobile phones, and radios, can trouble the telescope less.
3.
One of FAST's main jobs is to find pulsars(脉冲星), just like the "GPS of space". Pulsars can help people find their way back to Earth if they travel to the Moon or Mars.
Moreover, the telescope can search for life in space because it is amazing at finding signals(信号). It can "see" things that are 13.7 billion light years away. This means if you made a phone call from the Moon, FAST could hear it very clearly.

日积月累
in space 在太空
search for 寻找

任务一:
1. B 【主旨大意】该部分介绍了FAST的名称、大小和建造时间等,回答了“FAST是什么”的问题。
2. C 【主旨大意】由该部分内容可知,贵州远离城市,居住人口不多。因此,来自人类活动的设备对望远镜的干扰较小。故该部分解释了选择贵州作为建造地点的原因。
3. A 【主旨大意】由该部分的“One of FAST's main jobs is to find pulsars...”“Moreover, the telescope can search for life in space...”可知,FAST的主要任务之一是寻找脉冲星,这台望远镜还可以搜索太空中的生命。故该部分详细说明了FAST的功能。
任务二:
4. C 【细节理解】由文章中的“The answer is China's Five-hundred-metre Aperture Spherical radio Telescope (FAST).”可知,FAST是一台射电望远镜。
5. B 【数字计算】由文章中的“People started building it in 2011 and finished in 2016.”可知,建造历时约5年。
6. B 【细节理解】由文章中的“Guizhou is far away from cities, and not many people live there. So devices from human activities...can trouble the telescope less.”可知,人们在贵州建造FAST的原因是远离城市、人类活动对其干扰较小。
7. A 【词义猜测】由画线词后的例子“...TVs, mobile phones, and radios...”可知,这些是“设备”。
8. C 【细节理解】由文章中的“One of FAST's main jobs is to find pulsars...”“...the telescope can search for life in space...”可知,FAST的主要任务之一是寻找脉冲星,它还可以搜索太空中的生命。
