n[U] work done for or during school classes →homework
1. When students cheat, they are less likely to really understand their schoolwork. 作弊的孩子不太可能真正理解自己的功课。
2. And when you don't understand your schoolwork, your grades will probably suffer; cheating can only get you so far. 而如果你不理解自己的功课,那么你的分数就会受到影响--作弊给你带来的结果只能如此。
