阅读理解。

    When you are learning a language, listening, speaking and writing are important, but reading can

also be very helpful. When you read, you can not only learn some new words, but also learn how to

use them. When you read a passage, it gives you a good example for writing.

    Here are some good reading tips.

    Firstly, try to read at the right level (水平). Read something that you can understand. If it is too

hard for you, it is not interesting.

    Secondly, try to understand the new words. If there are four or five new words on a page, don't

use a dictionary. Instead, try to guess their meanings as you read. Mark (作标记) them with a pencil.

Then look them up in a dictionary when you finish reading, and write them in your own vocabulary

book. Try to remember them.

    Thirdly, try to read for a short time once a day. Fifteen minutes or half an hour every day is better

than two hours every Sunday. For example, you can read before you go to bed, or after you get up

or at lunchtime.

    Lastly, read something that interests you. Choose a newspaper, a book or a magazine about a

subject that you like. It will be easy enough for you to understand.
