中间段的写作步骤
1)阅读题目要求，找到可以用到的名词或动词
Write a letter of application according to the following situation. You saw an advertisement in this morning’s newspaper. A company needs a typist and you are interested. Write an application letter to that company. In your letter, provide the necessary information about yourself, tell them that you are qualified for that job.
2)写作顺序：背景介绍 + 情况咨询 + 原因分析 (名词具体化, 动词寻找近义词替换)
I read today’s Beijing Youth this morning, pleased to discover that your company is looking for a typist. I wonder if you could be free to have a pleasant talk with me, for all the requirements specified in your advertisement tend to fit my present situation. First, my typing speed is as high as 200 words per minute, which is the definite weight for a qualified typist. Second, I can speak and write English fluently, so I will be capable of typing both Chinese and English. Third and last, a warm-hearted woman who is always ready to help other people, I don’t think I have any problem while work with other colleagues. Under these circumstances, I firmly believe that I can contribute to prosperity of your company. On the other hand, a foreign company with an international background will certainly enrich my working experience and broaden my mind, thus paving a way for my prospective career.
结尾段：三句话

Sincerely Yours
