Someone 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 lost, it'll never come back. That is 2 we mustn't waste time.
Time is usually limited. Even a second is very important. We should make full use of our time to do 3 useful. Some people don't know the importance of time. They spend their limited time 4 . They don't know that wasting time means wasting part of their own life.
In a word, we should save time. We shouldn't 5 today's work for tomorrow. Remember: we have no time to lose.
