Dear my father and mother,
This letter is my inner feelings. I want to thank both of you for so many years’ care and help.
During my growth, you have made a lot of efforts and love for me. When I make a success, both of you are more excited than me, and support me to do better. Even though I have failed, you always share sorrow with me and encourage me not to give up. Especially, during my preparation for CET-4, the support from you is always everywhere. I have passed the exam successfully.
You love is so unselfish that I am deeply affected, so I will study hard to be a useful person and won’t make you disappointed. Anyway, I would like to express the deep gratitude to you.
With best wishes.
Sincerely yours,
Li Ming

Dear Mary,
You said in your letter that many of your classmates wore fashionableclothes, but you couldn\'t afford them so you felt very depressed. There are dif-ferent views on people\'s clothes. The followings are my ideas:
Firstly, you shouldn\'t put too much emphasis on physical appearance.
Remember that the most important task for you today is to concentrate on yourstudies. No matter what you wear, you will really look your best when youcome out first in your examinations.
Secondly, you should understand that it is a fine virtue to live in fru-gality. Just as a famous saying goes, Frugality is the mother of virtue.
Since your family can\'t provide you with enough money to buy fashionableclothes, it is all the more necessary for you to try to lighten the financialburden of your family. And you will find the virtue of frugality benefit youa lot in your future life.
I hope you understand what I mean. Hope you will take a positive attitudetowards life and will be happy again when you read my letter.
Yours,
Anne
