十分怀念讲授写作课的夏天，一个个激情四射、汗流浃背的日子。写作课的课时不多，根据我授课的内容和计划，在短短10个小时内要把写作的方方面面传达给同学，从10大困境及相关对策，到四大类题型构思与创作技巧，从高分句型讲到功能段落，从历年真题的考点到结构、思维和语言，从图画讲到图表再到情景和信函……同学们听得津津有味，结课时，却总感觉意犹未尽，似乎少了点什么。
的确，课堂上理论和典型范文都分析了，也全面阐释了句型模式和写作提高的各种训练方法，惟独由于时间有限，没有进行大量语言细节的现场训练，而写作的提高恰恰需要大量细节的分析和磨练，想到此至今还有些愧疚，一直想完成这个未完成的使命。课堂上一个重要的主题是关于英语创作的重要规律——seeking variety （追求语言丰富多变)。如何追求变化？课堂上来不及细说，下面举一个具体的例子，是我在考研教材中随机选出的两句话，从各种角度给出句型转换的方式，提供一些思路，算是我对各位同学的补偿吧。
下面例句选自一篇考研图画作文范文，主题是讽刺滥用简化字（simplified character)的现象。图画描述一个“展销会”的指示牌被简化成了“尸销会”，两名过路人受到惊吓、当场晕菜的场面。图画作文的首段往往要求进行图画场景描述，范文的开篇就有了这样两句话：
The picture shows two people reading the announcement on a billboard， and being shocked at the message. This is because the billboard is advertising a“sale of the dead bodies”。
语法错误：
首先需要纠正的是句子出现的一个语法错误：第2句一开始，在This is之后使用了because引导的原因状语从句，不符合语法要求。一般情况下，后面往往接名词性结构或形容词性结构作表语。此处只是作者想当然地把汉语“这是因为”生硬地翻译了出来，属于典型的Chinglish，口语中倒是屡见不鲜，而写作中则要有严格的语法观念，不能使用这样的表达。
This is because the billboard is advertising a“sale of the dead bodies”。
可修改为表语从句形式：The reason is that the billboard is advertising a“sale of the dead bodies.”
词语变化
段首句的picture、show和后面的shock可以选用其它同义词替换：
picture / cartoon / caricature
show / describe / depict / illustrate / portray
shock / amaze / astound / astonish /surprise
段首句变化
图画作文的段首句往往是“如图所示”或“从图画中可以看出”之类，下面为经常采用的一些句型：
As is shown in the picture，
As can be seen from the picture，
It is vividly shown in the picture that……
We can see in this picture that……
It is of considerable interest to see in the bizarre picture that……
因果表达变化
由于第二个句子是揭示原因的，英语表达中的因果关系词又非常丰富，所以句子改造就有了多种可能，感兴趣的同学不妨来个脑筋急转弯，用以下表达来试试你的创造力（此处大概有20种可能的因果变化)：
因果关系表达：
as， since， because， for， for the reason that， the reason（why…) is that
due to， because of， as a result of， on account of
so， thus， therefore， as a result， that''s why，
cause， lead to， result in， result from， attribute…to…， be responsible for
例1：The picture shows two people reading the announcement on a billboard,and being shocked at the message due to the advertisement of asale of the dead bodies.
例2：The picture shows two people reading the announcement on a billboard. Their being shocked at the message can be attributed to the advertisement of asale of the dead bodies.
句式转换：
为了加强同学们对语法知识在写作中的灵活应用，下面给出14种句式及语言调整的效果，内容上没有太大差异，只是请辨别每句话所侧重的句式：

1.主动句与被动句的转换
2.There be结构的采用；It is放在句首的形式
3.同位语的设置
4.疑问句形式
5.否定和双重否定形式
6.倒装句形式
7.强调句形式
8.虚拟语气形式
9.各类从句形式
六大类从句：主语从句、表语从句、宾语从句、定语从句、状语从句、同谓语从句
