Dear Tom,
Im very sorry that I cant go on a trip to Beijing with you next weekend, which I have promised you. Im writing to tell you the reason for it.(topic)
Just now, my cousin, Li Ming, who went abroad for further education last year, informed me that he would return the next Saturday morning. He asked me to pick him up at the airport with his parents. As you know, we havent seen each other for about a year, so Ill have to help him in the first place.
I really hope that you can accept my apologies and understand me. I would appreciate it if you allow me to fix another time to show you around some places of interest in Beijing.
Wish you have a good time this weekend!
dear,
i am terrible sorry for not having attended your class on time. because i had got a headache for several days and it is my first time to live in chongqing and i can not suit for the weather here quickly.
to be honestly, i like learning english very well and i have made my mind to learn it well both on spoken english and on written english. i think you will be my best teacher to help me improving my english level. so i apologize again for my not attend your class. i will make my great effort on english in the future and will not make you disappointment next time!
excuse me for my unintentional fault!
sincerely yours,
xin
