     We each have a memory (记忆力). That's why we can still remember things after a long time. Some

people have very good memories and they can easily learn many things by heart, but some people can only

remember things when they say or do them again and again. Many of the great men of the world have got

surprising memories.

      A good memory is a great help in learning a language. Everybody learns his mother language when he

is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living

with their parents in foreign countries. They can learn two languages as easily as one because they hear,

remember and speak two languages every day. In school it is not so easy to learn a foreign language because

the pupils have so little time for it, and they are busy with other subjects, too.

     But your memory will become better and better when you do more and more exercises.
