| Someone says, "Time is money." But I think time is 1 important than money. Why? 2 when money is spent, we can get 3 back. However, when time is 4 , it will never return. That is why we mustn't waste time. It goes without saying that the 5 is usually limited (有限的). Even a second is very important. We should make full use 6 our time to do 7 useful. But it is a pity that there are a lot of people who don't know the importance of time. They spent their limited time smoking, drinking and playing. They don't know that wasting time means wasting parts of their 8 . In a word we should save time. We shouldn't leave today's 9 for tomorrow. Remember we have no time to 10 . | ||||
