Dear Peter
I am extremely sorry to tell you that I am unable to go to your party this Sunday. It is very kind of you to invite me to your house and I hopefully want to celebrate your birthday with you and express my best wishes to you. Much to my regret, I will be absent from your party owing to the fact that the College Entrance Exam is just around the corner, for which I am now quite busy preparing. What’s worse, I have caught a bad cold lately and I am really not myself.
I am truly sorry. I hope you will forgive me and accept my sincere apologies. I believe we will have many more chances to get together. Shall we make it after the Exam?
I’m looking forward to your reply.
Best regards,
Li Hua



试题分析：考查应用文中的书信的写作。请你以李华的名义给你的一位美国留学生朋友Peter写一封电子邮件，说明你不能参加本周日在他家举办的生日聚会，要点都已经给出，书信类短文的关键在于要点要全面包括，不能有遗漏和省略。但是要点只是提纲，考生还要在此基础上增加细节，不要逐字逐句翻译，同时注意谋篇布局的顺序，运用合适的连接词连接全文，同时选择高级的词汇和语法项目让文章更有文采。审题时注意本文使用一般现在时，描述要尽量选择简洁的语言，运用合适的语法规则和词汇把各要点都准确表述出。难点在于选择词汇和句型，可以灵活运用高级词汇和固定短语准确表述。还要用适当的连接词被句子连接起来，这样文章显得更连贯。
【亮点说明】Much to my regret,这是固定词组“使我遗憾的是”，I will be absent from your party owing to the fact that the College Entrance Exam is just around the corner, for which I am now quite busy preparing. 这句话用了非限制性定语从句， I have caught a bad cold lately and I am really not myself.这里的I am really not myself.我不舒服，比I’m ill好多了， I hope you will forgive me and accept my sincere apologies.这句话用的是宾语从句，还有文章还用了What’s worse,这样的词组使文章更连贯。
