Question

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

       Most Americans find it hard to think what life would be without a car．However, some have realized the serious problem caused by cars．The polluted air is harmful and dangerous to health．

One way to get rid of the polluted air is to design a new car．That is what several large car factories, are trying to do．But to build the new car is easier said than done．Progress in this field has been slow．

Another way is to replace the car engine with something else．Engineers are working on some new cars．Many makers believe that it will take years to develop a practical model that pleases people．

To prevent the world from being polluted by cars, we’ll have to make some changes．Americans, for example, have to cut down the number of their cars．They are encouraged to travel and go to work by bike．Riding a bike is thought to help keep the air clean．

But this change does not come easily．A large number of workers may find themselves with no jobs if a car factory closes down．And the problem of air would become less important than that of unemployment．

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