Question

【题目】In most situations, light helps us see. But nowadays humans are using so much light that it is in fact a kind of pollution.

When it comes to looking at the night sky, too much light makes it d【1】for us to watch some of life’s most wonderful views: stars, planets and even galaxies(星系).

According to scientific research, about 2,500 stars can be seen by the human eye without u【2】any special equipment(设备). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big c【3】, people can’t see the sky filled with stars like they die in their childhood.

Light pollution influences more than just our view of sky. The latest research s【4】that lots of nighttime light can harm wildlife too.

When birds fly to a【5】place over cities, they sometimes get lost by the brightness and fly in circles u【6】they drop from tiredness. Sea turtles need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.

Too much light at night m【7】even influence human health, but scientists aren’t sure of that. They are still learning more.

In order to prevent things from going w【8】, governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are r【9】 needed.

Hopefully, in the near f【10】, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life too.

【9】really

【10】future

【解析】本文介绍了光污染的危害，让我们无法看清楚天上的星星，导致鸟类迷路，对人们的健

康也有害。政府和一些组织正在努力采取措施减少光污染。

【1】difficult

句意：当我们提到看夜空时，太多的光使我们很难观看一些生活中最精彩的风景：星星，

卫星甚至星系。根据后文的But because of light pollution, you can only see 200 to 300 stars

from today’s countryside, and no more than ten stars from a city.可知因为光太多导致看不清

星星，因此很难看到星星，故为difficult。

【2】using

句意：根据科学研究，没有使用任何特殊的设备，大约2500颗星星能被人眼看见。without

doing sth没有做某事，结合句意看星星可以使用特殊的设备，故为using。

【3】cities

句意：在大多数大城市，人们无法看见像他们在童年时看到的满是星星的天空。有most

修饰，故用复数名词，故我cities。

【4】shows

句意：最新研究表明很多晚间的光对野生动物也有害。此处表示研究表明，主语the latest

research是第三人称单数，故谓语用第三人称单数，故为shows。

【5】another

句意：当鸟在城市上空飞往另一个地方时，他们有时会因光亮迷路。修饰单数名词place，

表示另一个，故用another。

【6】until

句意：当鸟在城市上空飞往另一个地方时，他们有时会因光亮迷路，绕圈飞行，直到他

们因疲劳跌落。根据fly in circle? 6.? they drop from tiredness.可知表示绕圈飞行，一直

绕圈飞，直到飞累了，跌落下来，故用until。

【7】may/might

句意：晚上太多的光可能甚至影响人类的健康。根据but scientists aren’t sure of that.可知

表示不确定，应是没有把握的推测，故用情态动词may或might。

【8】worse

句意：为了阻止事情变得更糟，政府和一些组织正在工作来减少光污染。根据governments

and some organizations are working to reduce light pollution.可知要努力工作减少光污染，

应是为了阻止事情变得更糟，故为worse。

【9】really

句意：只有当他们是真需要的时候和地方，光才可以被使用。根据Many cities and towns

have taken action to reduce the use of lights at night.可知减少光的使用，因此只有真正需要

的时候或地方才用，修饰动词needed，故用副词，故为really。

【10】future

句意：希望在不久的将来，人类能再次享受干净的、漂亮的天空。in the near future在不

久的未来。故为future。
