施工测量的内容是什么？如何确定施工测量的精度？

阅读理解。

     Someone says, "Time is money." But I think time is more important than money. Why? Because when

money is spent, we can get it back. However, when time is lost, it'll never return. That is why we mustn't

waste time. Even a second is very important. We should make full use of our time to do something useful.

     But it is a pity that many people don't know the importance of time. They spend their limited time smoking,

drinking and playing cards. They don't know that wasting time means wasting some of their own lives.

     In a word we should save time. We shouldn't leave today's work for tomorrow.

     Remember: We have no time to lose.
