| Some one says," time is money." But I think time is 1 important than money. Why? Because when money is spent, we can get it back. however, when time is 2 , It'll never return. That is 3 we must't waste time. It goes without saying that time is usually limited. Even a second is very important. we should make full use of our time to do 4 useful.
