【答案解析】My Dear Fellow Students, I felt grieved to inform that Zhang Li, our best friend, has suffered from a serious disease and is now staying in hospital. Our friend is in great need of financial assistance to continue his medical treatment. So I am here to call for your helping hand. Our brother is in a bad health, and every cent from your pocket is important for his life. Your assistance in this matter will be greatly appreciated. If you want to be a donor, please register your name as soon as possible. Mr. Zhao will be in charge of the matter, and he is available in his dorm room. Thank you again for your sympathy, understanding and assistance. Sincerely Yours, Li Ming
