It is shown in the recent surveys that many college students copy papers from the Internet to save the trouble of doing their homework. In my opinion,this kind of academic dishonesty is very harmful to these students.First, copying papers from the Internet makes students lazy. Copying papers from the Internet seems easy and can save some time and trouble, therefore, students will do this more and more often and seldom work hard to complete their papers on their own. In other words, students will become lazier and lazier. Second. students can learn little from copying others’ work. Students cannot improve their abilities just by downloading papers from the Internet without their own thinking and working. What’s worse, once students get used to academic cheating, they may also cheat in other cases in the future, which will be very dangerous for them.To prevent academic dishonesty on campus, some punishment by the school may be necessary. But the most important thing is that teachers should talk to those students, and make them aware of the fact that copying others’ work cannot bring them any knowledge and that only by working hard can they improve themselves.
