丰富多变的英语句型能使文章读起来更加生动，相反的，相同句型频繁出现会使读者心生乏味。适当的变换句型不只能让文章读起来不单调，还能用来凸显重要的信息。例如，一则长句能包含很多信息，但也容易让读者抓不到重点；反之，简洁有力的短句更能把重要的信息传达给读者。
下面推荐两个能让文句型态丰富多变的小技巧：
1. 以长短句交错的方式改变句子节奏
把一堆结构和长度相似的句子凑在一起会令读者感到十分无趣，不如采用交错的长短句让文句多些变化比较不会让人昏昏欲睡。除此，长短句交错还可以用来凸显欲表达的重点。
范例：
The Winslow family visited Canada and Alaska last summer to find some native American art. In Anchorage stores they found some excellent examples of soapstone carvings. But they couldn't find a dealer selling any of the woven wall hangings they wanted. They were very disappointed when they left Anchorage empty-handed.
修改：
The Winslow family visited Canada and Alaska last summer to find some native American art, such as soapstone carvings and wall hangings. Anchorage stores had many soapstone items available. Still, they were disappointed to learn that wall hangings, which they had especially wanted, were difficult to find. Sadly, they left empty-handed.
2. 换句话说
如果一篇文章频繁出现近乎同样方式启头的句子会让读者感到索然无味（尤其是 “The...”、“It...”、“This...”、“I...”等），这时就可以“换句话说”——以不同的词汇和句子结构来代替。另外，选用句子启头方式不仅关乎句子结构，还能连带影响句意重点的传达。同时，转换启头后的句子未必能直接替换例句，因此需要对上下文做出适当的修改。仅仅修改一个句子便能带动整个段落，产生丰富的变化。
下面提供一个范例示范不同的句式来“换句话说”。
范例：
The biggest coincidence that day happened when David and I ended up sitting next to each other at the Super Bowl.
各种可行的修改方式：
- Coincidentally, David and I ended up sitting right next to each other at the Super Bowl.
