This is the Five-hundred-meter Aperture Spherical Radio Telescope (FAST, 500米口径球面射电望远镜).

As the largest radio telescope in the world, it is as big as 30 soccer fields (球场)!

 

What do we know about the “Sky Eye”?

A. It is a big pan in space.

B. It is the world’s largest radio telescope.

C. It looks like a soccer field.

D. It is the world’s first large telescope.

One of its jobs is to find pulsars (脉冲星). People call pulsars the “GPS of space”. On Earth, you use GPS to find different places. What if you travel to the moon or Mars? You can use pulsars to find your way back to Earth.

 

2. What can you use pulsars to do?

A. Find more stars.

B. Travel to the moon.

C. Find your way back to Earth.

D. Make GPS easier to use.

C

GPS:

Global Position System

(全球定位系统）

It also helps scientists look for life in space. FAST is about 2.5 times as sensitive (灵敏的) as the second-largest telescope in the world – the Arecibo Observatory in Puerto Rico. It can “see” things some 13.7 billion (十亿) light-years away. If you make a phone call on the moon, it can pick up the signal (信号) very clearly.

 

3. How can FAST help us find life in space?

A. By working with other telescopes.

B. By making phone calls.

C. By picking up signals.

D. By traveling to unseen places.

C

While reading

China opened FAST to the whole world on March 31. About 10 percent of FAST’s observation (观察) time, around 450 hours a year, is being given to scientists from other countries. Scientists can apply (申请) online to use it. “Sky Eye” has changed from “China’s eye” to “the world’s eye”.    

 

4. What does the last paragraph tell us?

A. China will use 10 percent of Sky Eye.

B. China will give Sky Eye to foreign scientists.

C. China can make a lot of money with Sky Eye.

D. China has opened Sky Eye to the world.

D

 

About 10 percent of FAST’s observation (观察) time, around 450 hours a year, is being given to scientists from other countries.

Fast 大约10%的观测时间，即每年450个小时给了其他国家的科学家。

此句中“around 450 hours a year”作为About 10 percent of FAST’s observation (观察) time的同位语成分，说明具体时长。
