Can you swim? Do you like swimming? How can you learn to swim? I think the best way is to go into the water and learn. I’m afraid you’ll never learn to swim just by reading books about swimming or looking at others swimming. It’s the same with the English study.

Listening and speaking are very important for beginners. The children in English-speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on radio. You may just understand a few words. It doesn’t matter. Just be relaxed, try to catch every word.

Somebody may be a good listener. But he dare not speak. He’s afraid of making mistakes. You know we sometimes make mistakes wh en we speak Chinese. Don’t be afraid. We must be brave. If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important. When there’s nobody to talk with, you can talk to yourself in English. It’s interesting and also a good way to practice your spoken English. Remember, the more you speak, the fewer mistakes you’ll make.

Reading and writing are more important for senior school students. First, we must choose the books w e’re interested in. A lot of reading will improve your language sense. This is the most important.

Keeping writing English diaries. We can also write English articles. You may even post them to English magazines. Don’t be afraid of failure. Failure is the mother of success.

Do remember: do more practice from now on and you’ll learn English well in this way.

( ) 62. How can you learn to swim?

A.By reading books about it. B .By looking at others swimming.

C. By having lessons on it.

D. By going into the river and learning.

( ) 63. We should learn English by .

A.Listening and speaking

B. Reading and writing

C. Swimming

D.A and B

( ) 64. What will you do with mistakes when you speak?

A . Don’t make mistakes

B . Study hard

B.Try not to speak English D. Don’t be afraid

( ) 65. What’s more important for senior school students?
