Maybe you are an ordinary student.   36   This is not necessarily so. 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 plan your time carefully. First arrange(安排) your time for eating, sleeping, dressing, etc, then decide a good, regular time for studying.   37   A weekly timetable may not solve all your problems, but it will force you to realize what is happening to your time.

Make good use of your time in class.   38   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.   39   If you do these things regularly, the material will become more meaningful, and you will remember it longer.

Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. The world won’t end if you don’t pass a test, so don’t be over worried.

  40   You will probably discover many others after you have tried these.

A. This will help you understand the next class.

B. Make full use of spare time to take note of what the teacher says in class.

C. Don’t forget to set aside enough time for entertainment.

D. There are other methods that might help you with your study.

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

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

G. You probably think you will never be a top student.

We have all heard it: these are supposedly the best years of our lives. 61       are these years really the best years we will ever like? Or will we look back on these years with a sense of regret?

When we graduate, what will we wish we 65___         (do) differently?

When we base our thinking on this idea, suddenly our understanding will be a little bit 66___         (good). But more than that, we will ensure that we can look back with a positive feeling.

   Of course, it is always difficult to be completely regret-free just by thinking about 67          ________we will regret in the future. Fortunately, here is a list of how to prevent some of the most common regrets:
