Dear Sir or Madam,

I am writing in response to your advertisement for a temporary position as a waiter. I am a 20-year-old student and would be able to work during June and July.

I do not have any experience but I enjoy working with people and am interested in a career in the catering industry when I leave university.

I would be very grateful if you could send me more information about the post available. I am looking forward to hearing from you.

Yours sincerely,

Li Hua

题目分析：这是封应聘信，应聘信属于公务信函，格式和用词比较规范。信的内容大体上分为三部：①写信的目的，②自我介绍，③要求。写作时注意下面几点：①写信的目的要直截了当地在信的开头提出。②自我介绍部分主要介绍自己的学历、工作经历、解决问题的能力等等。在行文、用词上要表现出自信、恳切的态度，语言简明扼要，突出介绍自己的优点，与众不同的特长或有利条件。还要紧扣用人单位的需求，巧用词语，说服对方，此职非你莫属。③最后提出进一步联系的途径，如：时间、地点。还可以主动提出接受面试。④求职信在写作特点上主要用第一人称以及动词的一般现在时。

【亮点说明】这篇范文很简洁，但是要点齐全，也有些好的词组和句子：in response to回应，enjoy doing 喜欢做…，be interested in对…感兴趣，looking forward to盼望，hear from收到…来信， I would be very grateful if you could send me more information about the post available.这句话用了if条件句。
