复杂句（Complex Sentence）某个句子成分直接由从属分句表示，那么这种句子便不是简单句而是复杂句。

The students would have made better grades if they had studied hard.

不少人认为”复杂句型”是高分的要件。所谓复杂句型就是利用各种子句、连接词、分词、片语等，将简单句扩充为绕来绕去的长句。首先，它不易阅读，又容易出错，尤其是中间有时态、用字等问题。

考试时，尽量将复杂句控制在两句内，中间穿插简单句。其实，阅卷老师想看到的是有变化的句型，以及连贯的内容，不是整篇令人眼花的复杂句。

下面是一个同学写一篇关于林书豪的最後两句：

“…. Graduating from a prestigious university, Jeremy gave up the road to Wall Street, choosing his dream – NBA. With his marvelous story, he is not only the person I admire most but also everyone’s role model, teaching everyone insisting dreams and goals.”

这两句都有分词片语，但用法上必没有正确表达作者的意思。从连贯的角度，第一句中，看不出第二句所提的 ”marvelous” 的地方，少了一句说明他的成名。看下面改写是否让意思更完整，句子更通顺：

“With an Economics degree from a prestigious university, Jeremy gave up Wall Street and pursued his NBA dream instead. He eventually became one of the fastest-rising stars in NBA history. His success story not just fascinates me but inspires me to stick to my goals. I want to be as successful as he in the future. That explains the reason I take him as my role model.”

你如果对分词构句没把握，忘掉它。上面示范的就是简单，但有变化的句子写法，每一句都用不同字开头，结构也不一样(划线部分)。而且意思连贯，从两句便成易读的五句。

易读又连贯的句子才是受欢迎的句子。
