【正确答案】 Dear President,
I am writing to suggest that a public speaking course be offered in our university. I am, like many others in our school, afraid of speaking in public and unable to express myself well. So such a course is highly recommended.
Actually, many universities at home and abroad have set the public speaking course as a compulsory or elective one. Numerous students have benefited a lot from it. This kind of course will not only endow us with a silver tongue but build up our confidence in whatever we do.
I would be most grateful if you could take my recommendation into consideration.
Yours sincerely,
Zhang Wei

【答案解析】 本文要求向学校提议增设公共演讲课程，因此收信人应是学校的相关负责人，称谓可以使用Sir／Madam／Professor／President等。信函的主体内容是提建议，但是除建议的具体内容外，像为何提出建议、想要取得的成效等相关信息也需阐述清楚。应用文写作中，投诉信的内容也涉及提出建议和改进措施，但要注意二者的区别，建议信没有“投诉”之意，因此语气应礼貌周到。
第一段：说明目的，阐述缘由。首先开门见山，表明信件的意图——建议增设演讲课程，接着说明原因．如学生害怕在公众面前说话，不善自我表达等。
第二段：晓之以理，说明益处。主要论述该课程的必要性和重要性。可先通过其他学校开设该类课程取得的效果从侧面说明该课程的必要性，再从一至两个方面具体阐明该课程的益处。
第三段：再次点题，表示期待。表达自己希望建议被采纳及感激的心情。
