Do you hope to do a lot of homework every evening? Are you interested in your English classes? Who do you want to teach you? Maybe you have lots of questions in your mind before school starts.

Well, I want to give you some good advice on these problems.

First, keep calm(平静). Don’t worry about all the problems you have. Put your heart into learning, and you can find something you are interested in. Do it actively.

Second, try your best to finish your homework quickly. Don’t spend a lot of time on it. Do more reading or writing in English. Think about the problems you have and solve them at once. Don’t stay up(熬夜) late, or you can’t study well the next day.

Third, invent something instead of copying(抄写) or repeating. If you can remember the words in your own way, you can tell your teachers you don’t like the way of copying them again and again. Be sure, you must pass the test. I think your teachers will agree with you. And they can give you some interesting work to do.

School is really a good place for us to learn. Believe in your teachers and yourself. You are the best one and you can do everything well.
