阅读下面的短文,并根据短文后的要求答题(请注意问题后的字数要求).

      Maybe you are an average student. You probably think you will never be a top student. This

is not necessary so, however. Anyone can become a better student if he or she wants to. Here's how.

Plan your time carefully.

      When you plan your week, you should make a list of things that you have to do. After    , you

should make a schedule of your time. First arrange your time for eating, sleeping, dressing, etc. Then

decide a good, regular time for studying. Don't forget to set aside enough time for entertainment. A

weekly schedule may not solve all the problems, but it will force you to realize what is happening to

your time.

Find a good place to study.

      Look around the house for a good study area. Keep this space, which may be a desk or simply

a corner of your room, free of everything but study materials. No games, radios or TV! When you

sit down to study, concentrate on the subject.

Make good use of your time in class.

      Take advantage of class time to listen to everything the teacher says. Really listening in class means

lesswork later. Taking class notes will help you remember what the teacher says.

Study regularly. 

      When you get home from school, go over your notes. Review the important points that your teacher

has mentioned in class. If you know what your teacher is going to discuss the next day, read the material.

This will help you understand the next class. If you do these things regularly, the material will become

more meaningful, and you will remember it longer.

Develop a good attitude towards the tests.

       The purpose of a test is to show what you have learned about a subject. They help you to remember

your new knowledge. The world won't end if you don't pass a test, so don't be overly worried.

      There are other methods that might help you with your studying. You will probably discover many

others after you have tried these.
