    Maybe you are an average (一般的) student. You probably think you will never be a top student. However,

anyone can become better if he or she does his or her best. Here are some tips to help you.

    ★ Plan your time carefully. You should plan your time for things such as eating, sleeping and dressing.

Then make a good, regular time for studying. But don't forget to set enough time for entertainment.

    ★ Keep your study quiet and clean. The study should have a desk, a chair and some study materials, but

no games, no radio and no television! When you sit down to study, you can put your heart into it. Make good

use of your time.

    ★ Listen to everything that the teacher says. Listening carefully in class means less work later. Taking

notes will help you remember what the teacher says.

your teacher is going to discuss next day, read the material. It will help you study better.

    ★ Develop a good attitude to tests. The purpose of a test is to show what you have learned about a subject.

too worried.
