解释成语亡羊补牢的寓意和用法英语作文范文
Dear Carl，
I am happy to know that you are getting along well with your Chinese.It’s quite natural that you should have difficulties with Chinese idioms, because their meanings are so much different from their apparent meanings.
The original meaning of the idiom attached is that when the shepherd found his sheep missing because of the broken sheepfold , he was advised to mend it in time.Today, the moral of the idiom is that when you make a mistake and do something wrong, you should correct it as soon as possible.It is somewhat equal to an English phrase “Late better than never”．For example, you can use the idiom to encourage your friend to work harder to make up the time he has wasted.Hope you will make more progress!
Best regards!
Yours，
Li Hua
