Nobody knows what time is like, for we cannot see it, nor can we touch it.

　　Time is abstract, which we can only imagine in our mind.

　　But we do know that time passes very quickly. Some students, however, do not know the value of time, nor do they know how to make the best use of it, for they waste it in going to films, playing games and doing other useless things.Why do we go to school early in the morning? Why do trains run so fast? Why do most people prefer taking buses instead of walking? The answer is very simple: we wish to save time because time is precious.

　　Today we are living in the twentieth century. We know that time is life.

　　When a person dies, his time has ended.Since life is short, we must devote our time and energy to our studies so that we may be able to serve our country and the people. But since time is invisible, we often neglect it. Lazinss. is the thief of time, for lasiness not only brings us a lot of harm, it also brings us failure. If it is necessary for us to do some work today, let us do it today and not leave it until tomorrow. Remember that time is more valuable than money.
