阅读理解。 Everyone knows that the favourite food of the Americans is the hamburgers. The best place to buy hamburgers is a fast-food restaurant(饭馆). In these restaurants, people ask for their food, wait just a few minutes.   Then when the food is ready,   they take it to their tables themselves. They can eat it in the restaurant or take the food out in a plastic(塑 料 的) box and eat it at home,   at work, or in a park.   At some restaurants people can drive up beside a window.   They ask for the food and a worker hands  it to  them through the window.   Then they drive off and eat in their cars.    Some fast-food restaurants also sell fish, chicken, sandwiches, soft drinks and so on.  Fast-food restaurants are very popular because the service(服务) is fast and the food is not too dear. For many people, this is very important. In the United States,   about 20% of all married(结婚的)  women with children work outside the home. They are often too busy or too tired to cook dinner for the family at night. So fast-food restaurants are a great help to others. 1. The passage talks about ________. A.
