四级作文题目：Your Help Needed
　　Dear friends,
　　I am writing to you, on behalf of the Student Union, to ask for your help for Li Ming, a schoolmate of ours from the Department of Computer Science. He is seriously ill now and has to have a heart transplant at once. To make things worse, he comes from the west of our country and his family is quite poor.
　　Li Ming is now confronted with the following difficulties. To begin with, he can't afford the medical expenses. His family doesn't have a good financial background. Moreover, his parents have already been deep in debt in order to send him to university. In addition, his family is far away and he needs someone to take care of him day and night. Only with intense care can our friend recover from his disease.
　　On no account can we see our friend suffer or die. He is in desperate need of your help, especially financial donations to help him pay for his expenses. Let's all give him our hands. Anyone who wants to offer help can contact us at 88588858 or you can email us bylove@sina.com. Please act without delay.
　　Yours sincerely,
　　Zhang Hua
　　Chairman of the Student Union
