The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.

Water pollution

A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead.

Air pollution

In big cities, factories, as well as cars, trucks and buses are the main cause of air pollution. Many people in cities now have serious health problems. For example, Mexico city used to be a beautiful sunny capital, but today it is always covered by thick brown clouds.

Soil pollution

In order to have a good harvest, most of the farmers use chemicals too much in their fields. That’s bad for the soil. But this kind of pollution is difficult to stop.

Hope for the future

These problems are very serious for our future, so all of us should do something to improve our environment. If we can stop pollution, our planet will become more and more beautiful and our health will be better. Let’s be greener people! 根据短文内容，选择正确答案。

Stop and listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.

Noise can be caused by many kinds of machines, such as motorcycles, jet planes (喷气式飞机), farm tractors, and power motors. And, to some people, rock music is also a noise.

What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. And most importantly, constant (连续的) loud noise can cause loss of hearing.

Scientists use a unit of measure called a decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands measure over 120 decibels. Noise at such high level causes the greatest hearing loss. 根据短文内容，判断正(T)误(F)。

Animals are people’s friends. But many wild animals are facing the danger of dying out, because the environment that they are living in has changed greatly. For example, their living area has become smaller and smaller because of pollution and the development of cities. They have no room to live in except the zoo. And many of the wild animals now can’t find enough food to eat. At the same time, man is killing off animals just for getting their fur, teeth and meat.

People should realize how serious the situation is and something should be done to protect the animals. We should set up some nature reserves so that animals can live freely. And people shouldn’t be allowed to kill the endangered (处于危险中的) animals. We should also do something to make our world cleaner. Fresh air, clean water and green grass are all important for animals. The death of the endangered animals will bring a disaster (灾难) to human beings. 根据短文内容，判断正(T)误(F)。

There are some easy things you can do to protect the environment and the earth. Choose ideas from the list or come up with a few of your own.

·Plant flowers, grass or trees.

·Whenever you visit a park or beach, take away what you bring there—keep rubbish in a bag until you can put it in a dustbin.

·Turn off the lights and TV sets when you leave the room. This can save a lot of electricity. ·Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

·Keep the doors and windows closed in winter to keep warm air in.

·Give your old books and magazines to a library instead of throwing them away. ·Give your old clothes to poor children you know instead of throwing them away. ·Use both sides of paper.

·Stop pouring dirty water into the rivers or lakes nearby.

·Encourage all your friends to do the same things you do to help protect the earth.

You don’t have to wait until Earth Day to do these things. Make every day Earth Day. If everyone makes a contribution to protecting the environment, the world will become much more beautiful.

Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable(一次性的) toothbrushes, toothpaste, shampoo and slippers.

Many guests like the idea because they don’t have to bring their own. But if you travel to Beijing, remember to bring these things of your own. That’s because some hotels in Beijing have no longer provided guests with these disposables (一次性用品). Many disposable things are made of plastic. People throw them away after only using them once. It’s a waste of natural resources (资源) and is very bad for the environment.

In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of lunch bowls every year!

Plastic can take 100 to 400 years to break down. So the less plastic we throw away, the better environment we will have.

So, wherever you travel, bring your own things and use them again and again. Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life:

Use cloth shopping bags, not plastic ones.

After using a plastic bag, wash it out and let it dry. Then use it over and over again. Do not use paper cups.

At your school canteen (餐厅), use your own bowls and chopsticks instead of disposable

ones.

根据短文内容，判断正(T)误(F)。

( )26.Many guests like to use disposable things because they are very convenient (方便的). ( )27.Some Beijing hotels have no longer provided guests with free TV programmes. ( )28.Plastic breaks down easily.

( )29.After using a plastic bowl or a bag, we’d better throw it away, because it’s too dirty to use

again.

( )30.We should use less plastic things and protect our environment.

(B)

Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage（损害；毁坏）. They can travel hundreds of miles in the wind before falling to the ground in the rain. And this “chemical rain” gradually（逐渐地）destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country’s trees had been damaged by the year 1986.

Time and time again there are serious accidents that pollute the air. In 1986 there was a serious accident at a nuclear power station in Russia. A cloud of radiation flew across the whole Europe. It is said that 125,000 people died in Russia as a result of illness caused by this accident.

In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured (受伤的). Many of the injured lost their sight. 根据短文内容，选择正确答案。
