例文:Mechanical Engineering Department Dalian University of Technology Dalian 116023 Liaoning,China November28,1999 Mr. WangXiming Mechanical Engineering Department Massachusetts Institute of Technology Cambridge, Mass. 02139 U.S.A. Dear Mr. Wang, Thank you for your letter of November 3,1999. I am sorry not to have written back earlier but time seems to pass so quickly. I learnt from your letter that you had received you master's degree. I would like to congratulate you on your splendid success. In this letter I am bringing you a piece of good news:your wife gave a birth of a boy last week and she ins in good health now. The baby weighed eight jin at birth. Yesterday my wife and some other neighbors went to the hospital to see your wife and to congratulate her on the birth. She told them that she had been nursed with the best care since she was in hospital. Now I'm taking the Visiting School Test in Beijing. If I pass the examination, I'll leave for America soon. If not, I'll wait for another chance. I've never been to the U.S.A., and I know little about the institutions and customs there. I hope that you will write to me and tell me more about them. With best regards to you and your classmates. Yours sincerely, Zhang Jiao
April 9, 2007Dear Jane, I took a telephone message for you just now while you were at the library. Peter James, the assistant at the computer center, said that someone had turned in your electronic dictionary and told you to pick it up tomorrow at 10:30 in Room 303. Remember to take your ID card with you. Yours, Mary给你个例子吧,不过我不知道发网后格式会不会自己变掉哦
