Passage 3

　　Cars are an important part of life in th United States.Without a car, most people feel that they are poor.An even if a person is poor he doesn't feel really poor when he has a car.

　　Henry Ford was the man who first started making发展制造 cars in large numbers.大量的He probably didn't know how much the car was going to affect American culture.The car made the Unite States a nation on wheels.And it helped make the United States what it is today.

　　There are three main reasons the car became so popular in the United States.First of all首先,the country is a huge巨大的 one and Americans like to move移动 around in it.The car provides提供 the most comfortable舒服的 and cheapest 便宜的form of transportation.With a car people can go any place without spending a lot of money.

　　The third reason is the most important one,though.The American spirit精神 of independence is what really made cars popular.Americans don't like to wait for a bus or a train or even a plane.They don't like to have to follow an exact准确的 schedule时间表计划表安排.A car gives them the freedom to schedule their own time.And this is the freedom that Americans want most to have.
