Someone says, “Time is money.” But I think time is    31   important than money. Why? Because when money is spent, we can get back. However（然而）, when time is    32   , it’ll never    33  . That is    34   we mustn’t waste（浪費(fèi)）time.
So we say that     35    is usually short. Even a second（秒）is very important. We should make full use of our time to do something    36   .
But it is a pity that there are a lot of people who do not know the importance of time. They spend their time smoking, drinking and     37   . They do not know that wasting time means wasting part of their own    38  .
In a word, we should save time. We shouldn’t    39   today’s work for tomorrow. Remember we have no time to     40   .
