雅思写作辅导：词汇的运用和句子的处理
一篇好文章的条件很多。除了内容丰富和组织紧密之外，词汇的运用和句子的处理，也起着决定性作用。
句子可长可短，同一件事，可以用不同的句式表达。如果句子清一色是简单句，文章必定很单调乏味。如果全篇充满了冗长的复杂句，读起来也很费力。最好的方法是以简单句为基础，配合适当的并列句和复杂句。简单句可长可短，通常要加些附属成分，如分词短语、介词短语、副词短语、不定式动词短语，以及节缩成分。
总之，作者可根据情况，使句子多样化，使文章灵活多姿。例如下列五个句子的基本概念一样，但是句式不同，内容重点也有些差别：
The goats grazed peacefully in the farm and were unaware of the approaching hunter. +2)
Grazing peacefully, the goats in the farm were unaware of the approaching hunter.
In the farm, the goats grazed peacefully and were unaware of the approaching hunter. - )
There were goats grazing peacefully in the farm, unaware of the approaching hunter.
As the goats grazed peacefully in the farm, they were unaware of the approaching hunter.
和的句式最常见;如果加上其他三种互相交替，句子不是更多样化吗？
