任务型阅读。请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。
注意：每空格1个单词。

      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:
      1. Plan your time carefully. When you plan your week, 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. Don't forget to set aside enough
time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize
what is happening to your time.
      2. 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.
      3. Make good use of your time in class. Take advantage of class time to listen to everything the
teachers say. Really listening in class means less work later. Taking notes will help you remember what
the teacher says.
      4. Study regularly. When you get home from school, go over your notes. Review the important points
that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read
that material will become more meaningful, and you will remember it longer.
      5. Develop a good attitude about 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 overly worried.
      There are other methods that might help you with your studying. You will probably discover many others
after you have tried these.
