Dear Mr.Smith,
I'm writing to invite you to the Traditional Chinese Culture Fair to be held by our school at the Art Center this Friday afternoon,from 2pm to 5pm.
Since this event aims to help more people learn about the traditional Chinese culture,the staff,all the students and their parents as well as anyone interested in it are welcome.(高分句型一)At the fair,related books,pictures,videos and objects will be exhibited,through which visitors will not only understand traditional Chinese culture much better but definitely feel the unique beauty of it.(高分句型二)
If you're interested,please come and enjoy it.And I'd be glad to offer any help.
Looking forward to your early reply.
Yours,
Li Hua
