They often eat breakfast in a hurry, but they have more time for dinner. Americans drink a lot of water (水), a lot of milk (牛奶), and a lot of coffee, but they don't drink much tea (茶). Some Americans like to eat in a cafeteria (自助餐馆). They can go there for breakfast, lunch, or dinner. A person takes a knife, a fork, a spoon, and a napkin (餐巾). Then he walks to a long counter. He can see all the food there. He chooses (选择) his meal and puts it on a tray. Then he pays (付钱) for it and carries his tray to a table.
