        Some students cheat (作弊) because they're busy or lazy and they want to get good grades without
 1    the time studying. Other students might feel that they can't   2   the test without cheating. Even when
there seems to be a "good reason" for cheating, it isn't a good   3 .
        A student who thinks cheating is the only way to pass a test  4   to talk with the teacher and his or
her parents so they can find some better ways together. Talking about these problems and   5  them out
will help feel better than cheating. 
        If a student is  6   cheating, the teacher may give a "  7 " on the test, send him or her to the head
teacher's  8   , and call his or her parents. Worse than the   9  grade may be the feeling of having
disappointed those people,   10  parents and teachers. A parent may worry that you are not an  11   person
and a teacher might watch you more   12   the next time you're taking a test.
       There are plenty of reasons why a kid shouldn't cheat, but some students have already cheated. If
that's you, it's  13   too late to stop cheating. Cheating can become a   14 , but a student is always able to
act better and make better 15   . It might help to talk the problem over with a parent, teacher, or friend.
