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.We may use more electricity by______.

A．turning off lights                        B．shutting down computers

C．turning up CD players                    D．turning off TV

3.______ will make global warming worse.

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

4.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

5.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.C

3.A

4.B

5.C

【解析】

試題分析：

1.通過閱讀最后一段可知，亂扔垃圾可以產(chǎn)生甲烷，從而使全球變暖。ABC可以防止地球變暖。所以本題選D。

2.通過Turn off lights, your television, and your computer when you’ve stopped using them.可知，ABD都不符合題意。所以本題選C。

3.通過閱讀可知methane(甲烷).是地球變暖主要原因。所以甲烷可以讓地球變暖變得更糟。所以本題選A。

4.通過閱讀第四段可知，我們用更多的電，產(chǎn)生的溫室氣體就越多。所以本題選B。

5.根據(jù)Trees take carbon dioxide out of the air when they grow.可知，樹吸收二氧化碳，而不是產(chǎn)生二氧化碳。所以本題選C。

考點(diǎn)：本題考查科普環(huán)保類

點(diǎn)評(píng)：本題的考查的題目，源于文章，但又必須通過閱讀，對(duì)文章加以理解方能得出答案，故本題有一定的難度。所以對(duì)于本文，應(yīng)該充分閱讀，盡可能從總體上把握文章的大意，還應(yīng)該結(jié)合一些生活常識(shí)。
