2. Something like: If I know today, why should I use the original sentence?

If young people don't work hard, the boss will be sad.

If you don't work hard when you are young, it's no use being sad when you are old. Remind us to cherish time and not to waste it.

If you don't cherish time when you are young and don't work hard, you can only regret and be sad when you are old. Used as object, attribute and clause; Used to persuade people.

It is also used to warn us to work hard while we are young, and not to accomplish nothing when we are old, which can only leave sadness and regret. Extended data:

"If a teenager doesn't work hard, the boss will be sad" comes from Yuefu's long poem. The full text is as follows: Sunflowers in the green garden bask in the sun.

Spring fills the earth with hope, and everything presents a scene of prosperity. I am always afraid that when the cold autumn comes, the trees in Ye Er will turn yellow and the grass will wither.

The river runs to the sea, and when will it return to the west? A lazy youth, a lousy age. Sunflowers in the garden are lush, and Ran Ran rises in the crystal sunshine.

Spring scatters hope all over the earth, and everything shows prosperity. I am always afraid that the cold autumn will come, the leaves will turn yellow and the grass will wither.

When can a hundred rivers run to the sea and return to the west? If young people don't work hard in time, they will only regret it for a lifetime when they are old. References:

Baidu Encyclopedia-Young people who don't work hard are pathetic.
