We often hear the saying"Time is money."But I think time is much more precious than money.Because If we lost time, we can't find it.But We can try to woke harder to get more money.No matter whatever you do ,you can not get lost time back.

　　"Time flies.time and tides wait for no men".You can see how important time is.Lunxun had said"I spent the time on my work while others are havig coffee."We must make good use of our time,especially for our students,we shouldn't waste time in playing games and the like.
