阅读短文内容，从下框的A— E 选项中选出一个最佳选项，填入题。 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. 小题1: ' 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. 小题2: 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. 小题3: Take advantage of class time to listen to everything the teacher says. Really listening in class means less work later. Taking class notes will help you remember what the teacher says. 小题4: 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. 小题5: 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 manv others after vou have tried these.
