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.
谁也不知道时间是什么样子，因为我们既看不见它，也摸不着它。
时间是抽象的，我们只能在我们的脑海中想象。
但我们知道，时间过得很快。然而，一些学生，不知道时间的价值，也不知道如何充分利用它，因为他们浪费在看电影，玩游戏和其他一些没用的东西。我们为什么一大早去上学？火车为什么跑得那么快？为什么大多数人愿乘公共汽车而不是步行？答案很简单：我们想节约时间，因为时间是宝贵的。
我们生活在二十世纪的今天。我们知道时间就是生命。
当一个人死后，他的时间已经结束了。既然生命短暂，我们必须把我们的时间和精力投入到我们的研究能够为我们的国家和人民。但由于时间是看不见的，我们经常忽视它。懒惰。是时间的盗贼，它不但给我们带来许多危害，也会使我们失败。如果这是我们今天做一些必要的工作，让我们今天做，不要拖到明天。记住时间比金钱更宝贵。
