题目内容

When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!

Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.

Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:

(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.

(2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.

(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.

A．use less electricity B．drive a car on sunlight

C．more electricity is used, less greenhouse gases are produced

D．less electricity is used, more greenhouse gases are produced

5.Which is the following is NOT TRUE according to the passage?

A．Driving cars on sunlight helps to stop global warming.

5.C

【解析】

试题分析：

1.通过阅读最后一段可知，乱扔垃圾可以产生甲烷，从而使全球变暖。ABC可以防止地球变暖。所以本题选D。

2.通过Turn off lights, your television, and your computer when you’ve stopped using them.可知，ABD都不符合题意。所以本题选C。

3.通过阅读可知methane(甲烷).是地球变暖主要原因。所以甲烷可以让地球变暖变得更糟。所以本题选A。

4.通过阅读第四段可知，我们用更多的电，产生的温室气体就越多。所以本题选B。

5.根据Trees take carbon dioxide out of the air when they grow.可知，树吸收二氧化碳，而不是产生二氧化碳。所以本题选C。
