所谓句子转换，就是将一种句式变成另外一种句式，或者用不同的方法表达相同的'语意，使句型多样化，借以提升写作的效果。例如形容词和副词可以有不同程度的比较而仍然保持原意。
下面的第一句是原级，可以变成第二句：比较级：
（1） Nancy is not so great as lrene.
（2） Irene is greater than Nancy.
同样的，主动语态可以变成被动语态而原意犹存。例如（3）是主动语态，（4）是被动语态，两句语意不变，只是重点改变。
（3） Mr Lin gave the good student a prize.
（4） The good student was given a prize by Mr Lin.
还有，一种词类也可以变成另一种词类并保留原意。例如：
（5） a. The customer examined the jewels very carefully.
b. The customer examined the jewels with great care.
（6） a. She tried to sing her song in an interesting way.
b. She tried to sing her song interestingly.
此外，一种句子也可变成另一种句子：
