閱讀理解。 Everyone knows that the favourite food of the Americans is the hamburgers. The best place to buy hamburgers is a fast-food restaurant(飯館). 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(服務(wù)) 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(結(jié)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.
