【正确答案】Dear Sir(s),
I am a university student majoring in English. We are going to have a course about American culture next term. My professor recommended a book called Essential to the American Culture to us, which is said to have been published last month and is selling well. So I want to ask some information about it. Could you tell me the price of the book plus the postage and packing? What's more, I wonder if there is a discount if I make a group order of 30 for my class. Your reply will be appreciated. Thank you!

【答案解析】[写作要点]
(i) 由于信函写作一般不要求考生写地址，所以格式问题不大。考生应把重点放在要点的表达、语言的组织上。
(ii) 不要加入太多与表达要点无关的表述。比如自我介绍，一两句带过即够。
(iii) 表述上注意多元化，不要太过生硬和随意。
