We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They’re in their shells ---sleeping .

Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep.

In spring the snail wakes up. Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can’t see very well. Its eyes, at the ends of the top feelers are very weak. But its sense of smell is very strong. It helps the snail to the new greens. Then the snail’s little mouth goes to work.

A snail’s mouth is no longer than the point of a pin(针). Yet it has 256,000 teeth! The teeth are so small that you can’t see them. But they do their work.. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones.

Mostly, a snail looks for food at night .But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.

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.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.

It is widely accepted that television is playing an important part in people's lives. But, there is a heated discussion as to whether television does good or harm.

Television keeps one learning more about present events, allows one to follow the most recent developments in politics and science, and offers various programs which are .both instructive and exciting. The most distant countries, the strangest customs and the most attractive scenes of nature are brought right into one's room or house.

However, some people insist that television is bad rather than good. They argue that it has brought about many serious problems. The major one is its effects on young people. Children are now so used to getting their information and entertainment from television that their ability to read and write as well as physical ability has been greatly weakened. Even worse than that, vulgar( 庸俗的) advertisements and poor programs may develop their bad tastes, shape their view points badly towards human life to such a degree that their minds might be destroyed.

In a word, television has both advantages and disadvantages. Whatever effects it has, one point is certain, television in itself is neither good nor bad. It is the use to which it is put that decides its value to society.
