七.听短文回答问题

今天我们要听一篇介绍美国快餐店的文章. 这篇文章谈到快餐店的种类,特色, 跟受美国人欢迎的原因.

请你注意听. 等一会儿我们要根据文章内容问你几个问题.

The favorite food in the United States is the hamburger, a kind of round sandwich of cooked ground beef. The favorite place to buy a hamburger is a fast food restaurant. At fast food restaurants, people order their food, wait a few minutes, and carry it to their tables themselves. People also take their food out of the restaurant and eat it in their cars or in their homes. At some fast food restaurants, people can order their food, pay for it and pick it up without leaving their cars.

There are many kinds of fast food restaurants in the United States. The most numerous sell hamburgers, french fries and milkshakes, which are traditionally popular foods among Americans. In addition, fast food restaurants that serve Chinese food, Mexican food, Italian food, chicken, seafood and ice cream are very numerous.

The idea of a fast food restaurant is so popular that nearly every kind of food can be found in one. Fast food restaurants are popular because they reflect American life style.

First, they are not formal restaurants. Customers wear any type of dress when they go to a fast food place.

Second, they are fast. People who are busy do not want to spend time preparing their own food or waiting while someone else prepares it. In fast food restaurants the food is usually ready before the customer even orders it.

Finally, most food in a fast food restaurant is not expensive. Therefore, people can afford to eat at a fast food restaurant often, while they may not be able to afford a more traditional and more expensive restaurant very often.

现在请你回答下面三个问题.每回答一个问题,老师就会念出正确答案给你听.

第一个问题是:
