Just as a famous saying goes: all work and no play makes Jack a dull boy. It is obvious that people should have adequate rest in order to work hard.

Yet some students especially those who are preparing for the college entrance examination are worried about their lessons and spend all their day time going over them. In their eyes they should sacrifice their rest time in order to get high scores on tests. As a result they suffer greatly from poor health and some of them may do poorly in the examinations.

In conclusion we should be aware that nothing is more valuable than health which is a foundation of one's success. With a poor health one can hardly succeed in anything he does. Therefore as student we should have enough rest to ensure a healthy body to work and study.

正如一句俗语所说，“只工作，不玩耍，聪明的孩子也变傻”。很显然，人们应该充分休息以便于更努力地工作。

然而许多学生，尤其是那些正在为高考而积极备战的学生，却总是担心自己的功课，从而把全部时间用于复习功课。在他们看来，为了在考试中获得高分，他们应该牺牲休息时间。然而，他们的健康却严重受损，一些人考试时反而做得很糟糕。

总之，我们应该意识到，没有任何东西比健康更重要，健康是成功的基础。一个人如果身体很差，做任何事都很难成功。因此，作为学生，我们应该有足够的休息以确保身体的强健，从而才能更好地学习和工作。
