People eat different things in different parts of the world.
In south China we eat rice every day. Sometimes we eat it two or three times a day, for breakfast, lunch and supper. We usually eat it with fish, meat and vegetable.
The Japanese eat rice, too. They also eat a lot of fish. They sometimes eat raw (生的) fish. In Africa, maize (玉米) is the most important food. People there make maize into flour(面粉). From this flour they make different kinds of bread and cakes.
In western(西方的)countries such as Britain, Australia and the U. S. A, the most important food is bread or potatoes. People there usually make their bread from wheat flour. They cook the potatoes in different ways. In England the most popular food is fish and chips. Sometimes people cook this food at home, but usually they buy it at the shop. They eat this food at home, in their work place, in the park or on the road. People call it "take-away" food.
