    There are many kinds of pollution around us,1 air pollution, soil pollution, noise pollution and light pollution. They are bad 2our health in many ways.

    Burning gas, oil and coal creates air pollution. It can cause sore eyes and 3 problems.

    With the increase of pollution and the development of industry, litter is everywhere. It makes our environment dirty. People put lots of rubbish in the land. Farmers use too many 4 in the fields. They destroy the soil. So soil pollution has become serious.

    Noise pollution can make people 5. For example, people may lose their hearing if they work in a 6  place for a long time. Too much noise can cause high blood pressure 7.

    Working for a long time in strong, changeable light 8 cause some kinds of illnesses. It makes people feel 9 and is especially bad for the eyes.

    With 10 pollution, our planet will become greener and our health will be better. Let's be greener people.

      Do you still get free plastic bags from the supermarkets? Things have changed.

      China has banned（禁止）free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1, 2008. It came because our country tried to make litter less. Making super-thin（超薄）plastic bags has also been banned.

      The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment (环境污染). The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.

      What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags（布袋）, and send them to their parent s as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect（保护）the environment.

Each year there is an increasing number of cars on the roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of the cars, driving trucks, building roads, or filling car with gas. Americans won't live without cars!

      Most Americans would find it hard to think what life could look like without a car. However, some have realized the serious problem of the air pollution caused by the car. The polluted air becomes poisonous and dangerous to health. 

      One way to get rid of the polluted car is to design a car that does not pollute. That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

      Another way is to take the place of car engine （发动机）by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.

      To prevent the world from being polluted by car, we'll have to make some changes. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and to go to work by bicycle. Bicycling is thought to help keep the air clean.

But this change doesn't come easily—a large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.

      Although cars have led us to a better life, they have also brought us new problems.
