五.听短文回答问题

刚才那个练习你都作对了吗? 现在我们来作今天的听力测验.今天老师要念的 文章是说汽车在美国变得很普遍, 人们以汽车为主要交通工具, 上班, 上街, 去 旅行都要靠汽车.

现在请你注意听, 等一会儿老师会根据这段文章问你几个问题.

Perhaps more than any other people, Americans have come to depend on their cars.

The family car has been a common thing since the early 20th century, and it has changed American life. Many people have moved outside of the large cities to the suburbs.

Some Americans spend two hours a day or more in their cars going to work and home again. Cars have become the means of transportation for most Americans going shopping, and even going on vacations.

Americans used to like big cars, and gasoline used to be very inexpensive. Recently, however, the cost of gasoline has increased, smaller cars have become more common.

Also foreign cars have become very common. Americans have bought large numbers of Japanese and German cars. They have bought cars from several other countries as well.

刚才那段文章要是你没有全懂, 没有关系, 等一会儿我请英文老师再给你念 一遍. 现在我们先来听今天测验的三个问题.

第一个问题是:

M: How long has the family car been a common thing in the United States?

第二个问题是:
