Question

【題目】As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets safe. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.

Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attractive meteor shower (流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn't be able to see the meteor shower as well. Due to the increase in street lights, I would surely be run over by a car.

Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you've ever taken a flight at night, the view is beautiful, but you must remember that all the light you see wastes electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity is worldwide.

One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted. One only needs to look at a row of street lights to see how much of the light shines upwards and lights the sky; a total waste of electricity.

Additionally, somewhere electricity needs to be produced, and the production of electricity creates pollution by releasing greenhouse gases. This affects the air we breathe and our quality of life.

Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny baby sea turtles become lost and follow lights on the shore instead of heading towards the sea.

Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.

【1】It is implied in Paragraph 3 that the best way to deal with light pollution is ________.

A. reducing the output of the lights

D. inventing environmentally- friendly lights

【2】Which of the following is the effect of light pollution?

A. Many animals species have died out.

B. More traffic accidents happen every day.

C. The air we breathe may be polluted.

D. It is much easier for us to watch meteor showers.

【3】What can be inferred from the text?

A. We are almost at a loss how to deal with light pollution.

B. Global warming results in light pollution in some way.

C. Astronauts can’t see clearly in space nowadays.

D. Some animals use natural light to direct their movements.

【4】What will probably be provided following the last paragraph?

A. Helpful tips for surfing the Internet.

Answer 1

【答案】

【1】B

【2】C

【3】D

【4】B

【解析】

試題分析:本文是一篇說明文，介紹了光污染對人類和動物造成的危害。光污染不僅會浪費能源、造成空氣污染，而且也會引起某些野生動物的死亡。目前科學(xué)家正在研究解決這一問題的辦法。

【1】B推理判斷題。根據(jù)第三段If you've ever taken a flight at night, the view is beautiful, but you must remember that all the light you see wastes electricity.可知關(guān)閉沒必要的一些照明可以減輕光污染，故選B。

【2】C細(xì)節(jié)理解題。根據(jù)第五段 This affects the air we breathe and our quality of life. 可知選C。

【3】D推理判斷題。根據(jù)倒數(shù)第二段內(nèi)容 as they become puzzled by the light可知有些動物靠自然光線來引導(dǎo)他們的一些行為，故選D。

【4】B 推理判斷題。文章末段提到Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.由此判斷下文要介紹一些減少光污染的方法，故選B。
