Dear john，
i am shocked to hear that you have a severe influenza and now are in hospital. i get this news from your mother and know you must be absent for half a month from the classes. do be careful while you are ill.
don’t worry about your lesson and i am willing to help you learn it when you return. we are best friends so i will never allow you to fall behind.
you can watch television or listen to radio programs to help pass the time and forget your pains while you recuperate. i do hope that i can see you soon and bring you some funny cartoons.
if there is anything you need me to do, just let me know. we all miss you and shall be happy when you are back.
your truly,
li ming

Dear Jane,
I am terribly sorry to learn that you didn’t do well in the final examination of computer. I know you must be very depressed about it, but please don’t lose your heart. You have done what you can and there is no permanent winner. I think all you need is to sum up your mistakes and make a good preparation for the next time. I believe you will make it. Come on, my dear friend.
Yours truly，
Tiffany
