Question

As the population of the planet increases, so does the number of homes, business, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand light. 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 own, lay down in the middle of the road and watched an attractive meteor shower(流星雨). If I did that today, I wouldn’t be able to see the meteor shower.

Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide （二氧化碳）pollution. 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 lights shines upwards and lights the sky: a total waste of electricity.

Additionally, 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 the light 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.

【解析】试题分析：本文是一篇科教类说明文。主要讲述了现在存在的一种的污染——光污染。详细说明了光污染的对于人类和动物的危害，文章最后作者号召人们减少光污染。

1.推理判断题。根据第三段第二句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.可知，大部分的没必要的户外用电都是浪费。因此推断最好的减少光污染的方式是在不需要照明的时候就不应该使用。故选C项正确。

2.推理判断题。根据倒数第二段第三句It has been long known that tiny baby sea turtles become lost and follow the light on the shore instead of heading towards the sea.可推断小海龟在爬向海滩时误将人造光源当成了自然光源从而迷失了方向，因此可知一些动物是靠自然光源来指引其方向的，故选D项正确。

3.推理判断题。根据最后一段最后一句Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.可知，最后作者讨论了遵循一些指导方针，在谷歌上搜索一下，就能获得很多关于如何减少光污染的想法。因此推断接下来作者会列举一些有助于减少光污染的方法。故选D项正确。
