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
