Question

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.

1.If we _____, we may make global warming worse.

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

C. plant trees                                               D. throw away rubbish

2. ______ will make global warming worse.

A. Methane            B. Cans               C. Newspapers                      D. Bottles

3.Using less electricity does good to global warming because_______.

A. the less electricity is used, the more greenhouse gases are produced

B. the more electricity is used, the more greenhouse gases are produced

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

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

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

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

B. When cars burn fossil fuels, they produce greenhouse gases.

C. When trees grow, they send carbon dioxide into the air.

D. By planting more trees, we can lower the number of greenhouse gases in the air.

 

Answer 1

1.D

2.A

3.B

4.A

【解析】

试题分析：这篇短文讲的是如何减少碳排放，减少空气中的温室气体，减轻温室效应，以使地球变暖不再加剧。文章中还给了我们几条具体的建议，从我做起，保护环境。

1.推理判断题。文章的最后给了我们三条建议，我们也可以为减少全球变暖做出自己的努力，其中最后一条就是告诉我们不要乱丢垃圾，由此我们可以判断，乱丢垃圾可能会使全球变暖加剧。故选D。其余三个选项都是有利于环境的。

2.细节理解题。根据文章最后一段，If rubbish is not recycled, it is put in the ground. There it rots and makes a greenhouse gas called methane，如果垃圾没有循环利用，被扔在地上。他们就会腐烂，产生出一种温室效应的气体甲烷。故由此推断甲烷会使温室效应加剧。故选A。

3.细节理解题。根据文章第四段To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases，为了发电，需要在发电厂里燃烧化石燃料，燃烧这种燃料会放出温室效应的气体。故我们用的电越少，这种气体产生的就越少，对环境就越有利。故选B。

4.推理判断题。根据文章的描述可知使用太阳能的汽车可以有助于减少温室效应，而并非完全阻止。由They burn fossil fuels in their engines, and send lots of greenhouse gases into the air可知B是正确的；由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可知C、D项正确。
