Directions: Suppose that Sarah, a friend of yours, has invited you to her birthday party, but you cannot go for some reason. Write a letter in about80 words to make an apology to her. Do not sign your own name at the end of your letter, using “Li Ming” instead. 假使你是李明，要写一封道歉信，相关内容如下：1．写信的目的-----道歉去不了她的生日宴会2．缺席的理由3．希望能获得原谅

正确答案为：Dear Sarah, I am terribly sorry to tell you that I am unable to attend your birthday part next Thursday evening. That is owing to the fact that my younger brother suddenly fell ill and was taken to a hospital this morning. I have to go there immediately and take care of him. As told by the doctor in charge, it will take around five days for him to recover and I have asked my boss for a leave. I really regret that I cannot go to celebrate your birthday personally and would miss the perfect chance of enjoying myself with all our old friends. I have chosen a small gift for you and will send it to you tomorrow to show my best wishes. Besides, please give my regards to our friends when you meet them at the party. Cordially, Li Ming
