求个介绍信和邀请函的格式,英文的 介绍信的格式
Dear Bob,
I'm writing to introduce you to Janice Dolan. I know Janice through the Brandon Theater Group, where, as you know, I am the technical director. Janice and I worked together on several local theater projects.
Janice is interested in relocating to the San Francisco area in the near future and would appreciate any recommendations you could offer her for conducting a job search for a theater position and any help you can provide with the logistics of relocating to California.
I've attached her resume for your review and you can contact her at janicedolan@email.com or 555-555-5555. Thank you in advance for any assistance you can provide.
Sincerely,
Y.Chow

Dear Beckham，
First of all，please allow me to express my heartfelt invitation to you. Since the Spring Festival is coming shortly，I sincerely invite you to come to China and spend the holiday with me.
Spring Festival is of much importance to Chinese people. It has a long history and Chinese have attached much importance to the holiday. To be exact，the Spring Festival has been the most significant holiday. The Spring Festival is to Chinese what Christmas is to the Westerners.
If you come，I am going to accompany you to fairgrounds（庙会），where you can have a close look at some of the Chinese traditions.
I am looking forward to your reply.
Sincerely Yours
Li Min
