Time waits for no one. If it flows away, it will never come to us again. We can't take charge of our time but we should know the importance of time and cherish time.
时间不等人。如果它流逝了，它就永远不会再回来。我们不能控制时间，但我们应该知道时间的重要性并珍惜时间。
Yesterday has become the history. Nothing we can do to save it. Tomorrow is not within our reach. We don’t know what will happen tomorrow. So the only thing we can do is to cherish what we have today and fight for tomorrow. Victory only belongs to those who work very hard! Therefore, we should make full use of today, fighting for what we want.
昨天已成为历史。我们不能做什么来挽救它。明天不是我们力所能及的。我们不知道明天会发生什么。所以我们唯一能做的就是珍惜今天，为明天而战。胜利只属于那些努力的人!因此，今天我们应该充分利用今天，争取我们想要的东西。
