英语改错
Schools should be clean and pure place.But now something bad happens.Some students cheated in examinations at school.As students,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 shools.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.
