     Schools should be clean and pure place. But now something bad happens. Some students cheated

in examinations at school. As students, we often have examinations, many of which are sometime too

difficult for us. In addition, some students not work hard at their lessons. So when taking examinations,

they are dishonest in order that get better results to please his parents and teachers. I think it wrong to

cheat in examinations though it breaks the rules of schools. We students should be honest and try to

get good grades in studying hard instead of by cheating in the examinations. What's more, we should

improve our study methods and get good prepared for examinations.
