It is known that some students cheat in exams. There are three reason. First of all, there are so many exams. Beside, the exams given are difficulty in some ways. Secondly, some students have to cheat in exams because of they are too lazy.The last reason is to please our parents and teachers.For some students,low marks brought them great pressure and make them depressing.In my opinion,cheating in exams are wrong.We should take active attitude to our studies,and try to get a mark what is true.
