阅读短文,选择正确答案。

     When you are learning English, listening, speaking and writing are important, but reading can be helpful.

When you read, you can not only learn some new words, but also learn how to use these English words. When

you read, it gives you a good example for writing.

     Secrets of good reading:

     Try to read at the right level. Read something that you can understand. If you need to stop every three words

to use a dictionary, it is not interesting.

     Try to increase the number of your new words. If there are four or five new words on a page, write them in

your notebook. But you don't have to write them while you read. Instead, try to guess their meaning as you read:

mark with them with a pen. Then come back when you have finished reading to look them up in a dictionary and

write them in your vocabulary and write them in your own vocabulary book. Then try to remember them.

     Try to read regularly . For example, read for a short time once a day. Fifteen minutes every day is better than

two hours every Sunday. Fix (固定) a time to read and keep to it. For example, you could read for fifteen

minutes when you go to bed, or when you get up or at lunchtime.

     Read what interests you. Choose a book or a magazine about a subject that you like, because you are going to

spend time and money reading it. So, choose an interesting book. You can also read newspapers. There are

many English newspapers in China. For example, 21st Century Teens, English Coaching Paper, etc. They are

easy enough for you to understand. There is something interesting in them.
