最后讲一讲扩写。扩写是缩写相对的书写形式。扩写要求在不改变原意的基础上，来扩展（或扩充）内容，扩大篇幅。原文可能是一篇结构完整的短文，或是一个提纲。扩写时要注意利用所提供的信息或提示。试图扩展情节场面。中心思想不变。例如：
请根据所学爱迪生的故事，将下面的提纲以Edison's Boyhood为题扩写成文。
1．Edison was born in 1847．
2．He didn't stay in school for long．
3．His mother taught him．
4．He had some strange ideas when he was young．
5．He became a GREat scientist when he grew up．
参考范文如下：
Edison's Boyhood
Edison was born in 1847．He was in school only for three months．His teacher didn't like him at all．He thought Edison was foolish and was not worth teaching．Edison's mother had to take him out of school and taught him herself．At home Edison read a lot and became very interested in science．
When Edison was very young，he had many strange ideas．When he was five，his father saw him sitting on some eggs，and asked what he was doing that for．Edison didn't reply．Instead，he asked his father why he was not able to hatch chickens while hens could．When he was in school， he often asked a lot of questions．Most of them had nothing to do with his lessons．Howerer，it is these strange ideas that helped him a lot．When he GREw up，he became a famous scientist．Everybody knows his name！
由此可见，扩写主要扩充内容。原文如果是写人叙事，扩写就需对原来人物的精神面貌，原来事件的发展变化，作比较深入细致的叙述。原文如果是发表议论，扩写就需要对原文的论点作比较充分的论证和阐述。这些都是对原文作合情合理的扩展，绝非是凭空虚构，随意乱加。
