However,there are people who try to get benefits by dishonest means.
For example,some students copy the exercises done by others or cheat in examinations in order to get good marks. The same thing may be said of a merchant who tries to get rich by deceving customers. Those people may succeed for a time,but sooner or later,they will be caught.
How can cheating on exams be prevented? The measures may vary from case to case.But I think,the students must first be well informes of the negative effect on the learning atmosphere of the university and the students'character. Then the students who were caught in the act of cheating can be criticizedpublicly, punished or even expelled from the university.
