信息填空

     根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项.  

         1    You probably think you will never be a top student. This is not necessarily so, however.

Anyone can become a better student if he or she wants to. Here's how:

Plan your time carefully. When planning your work, you should make a list of things that you have to do.

After making this list, you should make a schedule of your time. First your time for eating, sleeping,

dressing, etc. Then decide a good, regular time for studying.     2   A weekly schedule may not solve all

your 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

television. When you sit down to study, concentrate on the subject.

Make good use of your time in class.     3    Listening carefully in class means less work later. Taking

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 is going to discuss the next day, read that material.    4  If you do these things regularly, the

material will become more meaningful, and you'll remember it longer.

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

subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so

don't be over worried. 

        5  You will probably discover them after you have tried these.

A. There are other methods that might help you with your studying.

B. Don't forget to set aside enough time for entertainment.

C. Take advantage of class time to listen to everything the teacher says.

D. No one can become a top student unless he or she works hard.

E. Maybe you are an average student.

F. Make full use of class time to take notes of what the teacher says in class.

G. This will help you understand the next class.
