【答案解析】[范例] Dear Professor Wang, Allow me to introduce myself. My name is Li Ming. I am writing to you to ask for your help. I studied in the class you taught last year. I come from a country middle school, so I have trouble in reading English. Now I have some questions on reading comprehension, which I'd like you to help me with. I'd like to meet you some time to discuss them. I would appreciate it very much if you are kind enough to inform me of a convenient time and place to see me for half an hour. Hoping this won't trouble you too much. Thanks. Yours sincerely, Li Ming [文章点评] 文章第一段做了自我介绍，并说明了写信的目的；在第二段中，作者进一步介绍了自己的情况，表达了请求帮忙的意愿；在最后一段，作者提出了期望。 [语言注释] “Allow me to introduce myself．”意为“请容许我自我介绍”；“ask for your help” 意为“请您帮忙”；“a country middle school”意为“一个农村中学”；“have trouble in” 意为“在……方面有困难”；“I'd like you to”意为“我希望您……”，这是表达意愿的常用句式；“some time”意为“将来某个时候”；“appreciate”意为“感激”；“inform me of” 意为“告知我……”；“a convenient time”意为“方便的时间”；“this won't trouble you too much”意为“这不会给您带来太多麻烦”。
