We each have memory (记忆力). That’s why we still remember things after a long time. Some people have very good memories and they can easily learn many things in a shot time, 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 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 learns the sounds, remember them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages easily because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the students 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.

　　　　　　　　　　　　　　　　WHEN ARE YOU AN ADULT?
　　Many countries have ceremonies to celebrate their young people becoming adults. However, some countries do not. Instead, young people think of themselves as adults when they can do “adults” things. But when do you become an adult in the U.S.A.? Let’s look at what some American teenagers say.
　　Sam: I think you are an adult at 18. That’s when you can vote. You can help to choose who runs the state and the whole country. That’s grown up! My grandfather couldn’t vote until he was 21. They only change it to 18 in 1971. I guess they think we are more responsible at 18 now.
　　Jenny: I think it’s hard to choose. I get to drive a car at 16, don’t I? That’s a serious responsibility. When you have a driver’s license you show it to people to prove your age for all kinds of things. So that must be the age when you change from a young person to an adult. Because you have to prove you are that age and not a kid.
　　Suzie: I think there is something crazy about American laws about when young people can do things. So I can vote at 18 and drive at 16. So you would think that 18 is grown up, even if 16 isn’t. But then I can’t drink alcohol until I’m 21! If I’m an adult at 21, how can people stop me buying a can of beer in a shop?
