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.
