Someone says, "Time is money." But I think time is more 1 than money. Why? Because when money is spent, we can make it again. However, 2 time is gone, it'll never 3. That is4 we mustn't waste time.
It goes without saying that the 5is usually limited(有限的). Even a second is very important, we should make full use of our time to do 6useful.
But it is a pity that there are lots of people who do not know the importance of time. They spend their limited time smoking, drinking, and 7. They do not know that wasting time means wasting part of their own 8.
In a word, we should save time. We shouldn't 9today's work for tomorrow. Remember we have no time to 10.
