从对1992年1月到2002年12月间 CET -6考试作文题目的分析来看,各种题型出现的机率很不均等.其中提纲作文18次,约占85.5%(题目+提纲14次,题目+提示4次);图表作文2次,约占9.5%;关键词作文1次,约占5%.从目前了解的情况看,今后出现图表作文的可能性已不大,而关键词作文出现的可能性呈上升趋势.因此考生在充分准备提纲作文的同时,也要重视关键词作文的写作思路和方法.

关键词作文分两种情况,考生要视具体情况采取相应的做法:

1.如果给出的关键词已经分了组,考生就可以找出每组中的核心词,结合题目认真思考,写出段落主题句,再根据主题句去展开各段落的写作.

2.如果关键词没有分组,考生首要的工作就是结合对题目的思考,认真给关键词分组,从而确定段落中心,写出段落提纲或主题句.这个前期工作做得到不到位直接关系到后面的写作.仓促动笔,将不可避免地出现疏漏或失误.对于写作基础很好的考生,建议打好草稿,将关键词分组和段落提纲一步完成.

针对上述两种情况,可分别采取如下步骤:

以下好学英文网为大家提供例文，并予以分析：

Directions:You are allowed 30 minutes to write a composition about Invention in three paragraphs.You should base your composition on the following outlines.You are required to write in no less than 150 words.
Key words and expressions:
a.wheel,change,the way man lives
b.microscope,computer,science and technology,advance
c.explore space

根据题目,可以判断这是一篇说明文.已分组的关键词框定了写作思路.因此文章的概要就很清楚了.将文章分三段,写出每段的主题句(主题句中无须写进所有的关键词).

1.There have been many inventions that have changed the way man lives.
2.Modern inventions have advanced science and technology and made people healthier,and man's life longer. hxw.red
3.Now man has the desire to explore space.

很明显,第一个主题句即可看作全文的中心思想.用wheel举例说明车轮的发明改变了人类的生活方式,引出下文.第二段可用列举法举出有代表性的现代发明,说明它们对人类生活所产生的影响.可能的话,还可从invention本身的某种角度作简要解释.第三段主要写人类探索太空的愿望和正在进行的工作.全文要紧扣"发明"这个主题,坚持"改变"这个中心.

英文参考范文：
Invention

There have been many inventions that have changed the way man lives.One of the first great inventions was the wheel,which is still of importance today.The wheel makes it easier to travel a long distance. With the help of wheels people have almost explored all the land on the earth.

Since the second half of the 19th century many great inventions have been made.Microscopes,radios,computers etc. appeard one after the other.With thead-vance of science and technology,people become healthier,and man's life is longer.
Moreover,inventions make further inventions possible,for new machines or technology are not merely a product of theinvention,but a source of fresh creative ideas.

Now man has the desire to explore space.The first step was made when manned spacecraft landed on the moon.That was certainly just a beginning.New inventions will someday allow us to do something we have never imagined.We young people should get ready to invent something new and useful.
