阅读理解。

     Some students think it difficult to learn English well. That’s because they don’t find the right way. I

think reading is very important for students. The more you read, the better you’ll understand. Reading

is helpful to listening, speaking and writing.

     If you often read English aloud, you’ll improve your listening. On the other hand, listening a lot can

help you to read better. Reading English everywhere when you are free, if you wish. You can get a lot

of knowledge when you read. Sometimes you need to express your ideas, you can either speak or write.

That means you are using what you learned from reading. The same as Chinese, the more you read, the

better you can write. If you want to remember something, you should read again and again. So from now

on, you’d better do more reading. It’s a good way to learn English well.
