【答案解析】[范例1] Dear Wu Hart, It just dawned on me that I had never returned the 40 yuan that I borrowed from you last month to buy that old porch swing at the commodities fair we went to on Central Avenue. I'm enclosing a check and apologize for the oversight. I wish you had reminded me. I should have returned the money as soon as possible. The swing creaks and squeaks, but is very comfortable...a great place to sit and watch the world goes by. Be sure to let me know when you hear of another commodities fair next time. I am sure I'll bring enough of my own money. Fondly, Li Ming [范例2] Dear He Jie, Much to my regret that I am unable to attend your birthday party next Tuesday evening. That is owing to the fact that our physiological teacher has assigned us quite a few experiments and required us to hand in our reports of the results before next Thursday, and it happens that your birthday party is going to be held when I will be fully occupied by the assignments. So I am terribly sorry that I cannot go to celebrate your birthday personally. I really regret that I would miss the perfect chance of enjoying myself with so many friends. But I'd like to wish you a happy birthday and ask the postman to send you in advance a gift which is a small token of my best wishes for you. Besides, please give my regards to our friends when you meet them at the party. Cordially, Li Ming [范例1文章点评] 文章第一段说明了应该道歉的事情；第二段中，作者正式道歉，并声明归还所欠钱款；在第三段，作者描述了所购物品的优点；在最后一段，作者表达了自己的愿望。 [范例1语言注释] “It just dawned on me that”意为“我才想起来……”；“swing”意为“秋千”；“commodity fair”意为“商品交易会”；“Central Avenue”意为“主大街”；“enclose” 意为“附上，装入”；“apologize for”意为“为……道歉”；“oversight”意为“疏忽”； “remind”意为“提醒”；“as soon as possible”意为“尽快”；“creak”意为“摇摇欲坠”；“squeak”意为“吱吱作响”；“watch the world goes by”意为“观看周围的环境”； “Be sure to let me know”意为“一定要告诉我……”。 [范例2文章点评] 文章第一段表达了抱歉之意，并且说明了原因；在第二段中，作者再次为自己不能亲自参加聚会而致歉，对错过与朋友相聚的机会而深感遗憾，最后请对方在聚会时向朋友转达自己的问候。 [范例2语言注释] “Much to my regret that”意为“我深表遗憾的是……”，这是表达歉意的常用句式； That is owing to the fact that”意为“这是因为……”；“assign”意为“指派，分配”； “hand in”意为“上交”；“report of the result”意为“实验报告”；“it happens that”意为“碰巧的是，……”；“be fully occupied”意为“忙于……”；“assignment”意为“任务”；“I am terribly sorry that”意为“非常遗憾的是……”，这也是表达歉意的常用句式：“celebrate”意为“庆祝”；“I really regret that”意为“我确实感到遗憾的是”；“miss the perfect chance of”意为“错过，失去……的绝好机会”；“enjoy myself”意为“玩得高兴，过得愉快”；“wish you a happy birthday”意为“祝你生日快乐”，这是表达祝贺的常用短 语；“in advance”意为“提前”；“token”意为“象征，纪念品”；“give my regards to” 意为“代我向……问好”，这是表示问好的常用短语。
