     Cheating can happen in a lot of different ways. When people cheat, it's not fair to other people, like

the kids who studied for the test or who were the true winners of a game.

     Many people like the action of cheating. It makes difficult things seem easy, like getting all the right

answers on the test. But it doesn't solve the problem of not knowing the material and it won't help on the

next test -unless the person cheats again.

     Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad

because they know they are not really earning that good grade. And, if they get caught cheating, they will

be in trouble at school, and maybe at home, too.

     Some kids cheat because they're busy or lazy and they want to get good grades without spending the

time studying. Other kids might feel like they can't pass the test without cheating. Even when there seems

to be a "good reason" for cheating, cheating isn't a good idea.

     If you were sick or upset about something the night before and couldn't study, it would be better to

talk with the teacher about this. And if you don't have enough time to study for a test because of swim

practice, you need to talk with your parents about how to balance swimming and school.

     A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her

parents so they can find some solutions(解决办法) together. Talking about these problems and working

them out will feel better than cheating.
