Ⅳ.阅读理解。（30分）（A、B两篇每小题2分，C篇每小题2分）
(A)
In common with the ( http: / / www.21cnjy.com ) other countries, Britain has serious environmental problems. In 1952, more than 4,000 people died in London because of the smog. The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot.
Today, London is mu ( http: / / www.21cnjy.com )ch cleaner but there is a new problem: smog from cars. In December 1991, there was very little wind in London and pollution increased a lot. As a result, about 160 people died from pollution in just four days.
Part of the pro ( http: / / www.21cnjy.com )blem is the new“out of town”shopping centers. In the past, people often walked to shops near their home or went by bus. Now, many people drive to the new shopping centers. As a result, the small shops have disappeared and more people have to travel to do their shopping.
Critics say that Br ( http: / / www.21cnjy.com )itain needs better and cheaper public transport. Transport in Britain is very expensive. An early morning train trip from Glasgow to London (about 600km) can cost about 100 pounds, for example. A short 15-minute bus trip can cost over 1.00 pound.
Many people are tryin ( http: / / www.21cnjy.com )g to reduce the use of cars in Britain. Some cities now have special bicycle paths and many people cycle to work. Some people also travel to work together in one car to reduce the pollution and the cost.

What do people ( http: / / www.21cnjy.com ) do with their old, out of date but still useful computers Most people don’t know how to deal with them. Many old computers are put away. Many more are simply thrown away as rubbish.
Finally, some compa ( http: / / www.21cnjy.com )nies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products(产品). Dell, Hewlett Packard and other companies now also take back some old computers of their own brands.
In some countries, ( http: / / www.21cnjy.com )laws have been passed, puter companies have to pay for collecting and recycling their used products. And 70% of the computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers which are easier and cheaper to repair and upgrade(升级).
Yet many people are ( http: / / www.21cnjy.com )throwing away good computers, while others cannot afford them at all. Hundreds of organizations are working on this problem. They collect and repair old computers. Some also teach others how to repair computers. These repaired computers then go to schools, charities(慈善团体) or people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things and cut down waste, too.

Boys and girls，
An expert ca ( http: / / www.21cnjy.com )lled Jim Greenlaw from Canada will come to our school this Sunday. He will give a report on “Saving Our Earth”. The report will start/begin in our school hall at 9: 00 in the morning. Remember to bring your notebooks. Please keep quiet and don’t throw rubbish about.
That’s all. Thank you.

As time goes ( http: / / www.21cnjy.com ) by, man is making the earth sick. People cut down too many trees and throw rubbish away here and there. Many factories pour waste water into rivers and lakes. As a result, a lot of rich land has changed into desert, leaving only sand. Many rivers and lakes are dead now. The air is becoming dirtier and dirtier. The temperature on the earth becomes higher and higher. Many people now are in bad health. I think everyone is supposed to reduce the waste. Recycling can not only protect the environment but also save money. We’d better not buy bottles or boxes which people can use only once. If we are greener people, our world will become more and more beautiful.
