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(溫室氣體). 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(腐爛) 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

【答案】

 

1.D

2.A

3.B

4.A

【解析】

試題分析：這篇短文講的是如何減少碳排放，減少空氣中的溫室氣體，減輕溫室效應(yīng)，以使地球變暖不再加劇。文章中還給了我們幾條具體的建議，從我做起，保護(hù)環(huán)境。

1.推理判斷題。文章的最后給了我們?nèi)龡l建議，我們也可以為減少全球變暖做出自己的努力，其中最后一條就是告訴我們不要亂丟垃圾，由此我們可以判斷，亂丟垃圾可能會使全球變暖加劇。故選D。其余三個選項(xiàng)都是有利于環(huán)境的。

2.細(xì)節(jié)理解題。根據(jù)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，如果垃圾沒有循環(huán)利用，被扔在地上。他們就會腐爛，產(chǎn)生出一種溫室效應(yīng)的氣體甲烷。故由此推斷甲烷會使溫室效應(yīng)加劇。故選A。

3.細(xì)節(jié)理解題。根據(jù)文章第四段To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases，為了發(fā)電，需要在發(fā)電廠里燃燒化石燃料，燃燒這種燃料會放出溫室效應(yīng)的氣體。故我們用的電越少，這種氣體產(chǎn)生的就越少，對環(huán)境就越有利。故選B。

4.推理判斷題。根據(jù)文章的描述可知使用太陽能的汽車可以有助于減少溫室效應(yīng)，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是正確的；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項(xiàng)正確。
