The world itself is becoming much smaller by using modern traffic and modern communication means(通讯设备). Life today is much easier 　　①　 　it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear ②it.

Man has been polluting the earth. ③The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up(耗尽) or the river was dirty in a place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.

Many countries are making rules to fight pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.

The pollution of SO₂ (二氧化硫) is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution.

The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in population at the same time.

(C)

No air means death. Although we can’t see it, there is air around us. So air is everything and it gives life to every living thing. Bad air makes people ill. We must have fresh air to keep us in good health.

In the city, there are a great many people and there are too many cars running on the roads. The gas which the cars give out(排出，散发出) is full of poison(有毒物). Every day we breathe it in again and again. This makes us feel sick.

Besides(除了)cars, there are many factories, too. From chimneys(烟囱) of these factories, the smoke is usually black or grey. This kind of smoke, when mixed with(与……混合) the air, is dangerous to our health. It is because the smoke contains(包含) many poisonous(有毒的) solids(固体) and gases. In order to keep us healthy, we have to go out to the countryside to breathe more fresh air. We can also climb up hills to get the fresh air.

New rules and behavior standards(行为规范) for middle school students came out in March. Middle school is going to use a new way to decide who the top students are. The best students won’t only have high marks(分数). They will also be kids who don’t dye(染) their hair, smoke or drink. The followings are some of the new rules.

Tell the truth. Have you ever copied someone else’s work in an exam? Don’t do it again! That’s not something an honest(诚实的) student should do. If you have played computer games for two hours in your room, don’t tell your parents you have done homework.

Do more at school. Good students love animals and care for other people. April is Bird Loving Month in China. Is your school doing anything to celebrate? You should join! In that way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone.

Have you ever quarreled(吵架) with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, not only yourself.

Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you’ll discover EarthⅡsomeday. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them, because new ideas make life better for everyone.

Protect yourself. Has someone ever taken money from one of your classmates? Don’t let it happen to you. If you have to go home late, you should let your parents know.

Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren’t good for kids, so try to look at web pages that are good for you. You can use the web for fun or homework. If you can’t find any good web sites for children, here are two: http: //; http: //.

In most parts of the world, many students help their school make less pollution. They join in “environment(环境) clubs”. In an environment club, people work together to make our environment clean.　 Here are the things students often do.

Turn off the water! Do you know that some toilets(厕所) can waste(浪费) twenty to forty tons of water an hour?　 In a year, that would fill a small river! In environment clubs, students mend those broken toilets.

No-car day. On a no-car day, nobody comes to school in a car ---not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jump, bike or run.

Use your legs! It’s lots of fun!

No-garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!

We love our environment. Let’s work together to make it clean!
