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

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

One way to get rid of the polluted air is to build 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.

Anoth er way is to take the place of the car engine 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 cars, we'll have to make some changes in the way many of us live. Americans , for example , have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle . Bicycling is thought to h elp keep the air clean.

But this change does not 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.

Almost every family in America or England buys at least one copy of a newspaper each day. Some people buy as many as two or three different papers.

Why do people read newspapers?

Newspapers supply us with news about events in our hometowns, in our country, and in other parts of the world. Today we can read about important things that took place in foreign countries on the same day they happened, even in countries far away. But hundreds of years ago, news of things took months or even years to travel from one country to another. In those times, news was often passed from one person to another and never completely true. Newspapers today supply us with more than just what happened in our country or in other countries. If we want to know what the weather will be like, we can read the weather reports. If we want to find out what films are being shown, or what plays or concerts we can go to we can look in the newspapers.

In many countries people put notices in newspapers if they are trying to get a job, hunting for a house or rooms that they can rent, or even when looking for a person who is lost.
