Quote a famous saying and write a sentence as follows:

1. An inch of time is worth an inch of gold, but an inch of gold can't buy an inch of time, so we should cherish time from childhood and study hard so as not to regret it when we grow up in the future. In this exam, I got the first place, which is really worthy of being: everything comes to him who waits.

2. In this cultural festival celebration, many foreign tourists came here, and China volunteers warmly received them. As the saying goes, "It's a pleasure to have friends from afar".

3. The ancients said well: "An inch of time is worth an inch of gold, and an inch of gold can't buy an inch of time." So we should cherish the present time and study hard. Strive to improve their own quality and make unremitting efforts to become useful talents in the future!

4. Time flies, and the good times will never come back. Each of us has only one life, so we must cherish our life and seize the opportunity to work hard. A lazy youth, a lousy age. Only when you are young, you will be rewarded when you grow up.

5. If we want to get good grades, we must study hard. There is a famous saying, "there is a road to diligence in the mountain of books, and there is no limit to learning the sea."

6. Teacher Li taught his students: "We must adopt a realistic attitude, knowing what we know is knowing, not knowing what we don't know, and don't force the ignorant to think we know". Failure is not terrible, what is terrible is that you retreat after one failure. "Failure is the mother of success."
