People eat different things in different parts of the world. In the south of China people eat rice every day. Sometimes they eat it two or three times a day, for breakfast, lunch or dinner. They usually eat it with fish, meat and vegetables.

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) countries, such as in Britain, and in the USA, the most important food is bread and potatoes. People there usually make bread from wheat flour. They cook potatoes in different ways.
