根据所学的知识改写下面这封推销信：Dear Customer

1)第一段一开始作者要求读者抽几分钟时间阅读此信，但没有提出此信的主题或与此紧密相关的任何东西。

2)第二段的语气则完全是以作者为中心的(We want you tO be aware…)，听起来有点居高临下，盛气凌人;另外，在介绍产品之前谈及价钱问题也不太妥当。

3)第三段中介绍产品所用的词汇和句子显得十分空洞，令人费解而且还有迎合奉承之嫌。

4)第四段强调价格的低廉，但这种表述的方法不妥。

5)第五段敦促读者采取行动，并规定了限期，但没有说明原因。

建议将此信改为：

Dear Customer：

Many of you own a computer at home or in the office，but not many of you are expert with it，You may sometimes come across technical problems that you are unable to solve by yourself.Therefore，you may often.say to yourself.“How I wish I had an expert with me all the time”or“On computing work.I wish I were better instructed whenever I have problems.”

(通过使用两句引言，提出了电脑用户常常碰到的问题，以引起读者的兴趣。)

The newly—published handbook PROFESSOR WINDOW 95 is the solution to your problem.It is your expert telling you how to use the machine and how to obtain the perfect performance in word processing system.

(上段提出了问题，这段直接进入正题：解决问题的方法，即使用PROFESSOR WINDOW95软件系统能帮助解决所有的问题。)

The handbook is the work of a group of university professors of computer science and three experienced computer technicians.It is not an introductory textbook to you but a hand--on tutorial providing easyto—read application approaches.As many as two hundred questions and answers are provided tO solve your daily usage problems.The technological concepts and terms are explained with more than 100 photographs and illustrations in the 260一page handbook.You can read about keys in the book without calling at the technician’S office whenever you get lost in processing.What is more，the bilingual explanation will make the job easier for users either speaking Chinese or English.

(十分具体地描述产品的特点，优点和用途，而不是泛泛地，抽象地介绍。)

(敦促读者采取行动，规定了限期，并通过提供一种奖励使读者能迅速作出决定。)
