确定文章的框架和语法结构是雅思议论文写作的前提。
文章的framework即文章的结构永远是决定一篇写作是否达到要求的最重要的标准，即一篇文章好不好，首先看的不是他的句型， 词汇， 或是论点等。 而是段落之间的衔接一定要十分清楚，我们不能老是采用大三段的形式-开头，经过，结尾。我们可以多用用连接词，例如：first of all, morever, secondly, lastly等。另外可以多分自然段，给考官一目了然的感觉。
以下原则是在考虑选择何种语法结构时可以参考的原则：
1. 一个句子的主语和谓语动词应该能够反映句子中的最重要的意思。例如：
The situation that resulted in my grandfather's not being able to study
engineering was that his father needed help on the farm.
从意思上来分析，上面这句话需要表达的重要的概念是“grandfather’s not being able to study”，而在表达这个概念时，原句用的主语是situation，谓语动词是was，不能强调需要表达的重点概念，可以改为下面这句话：
My grandfather couldn't study engineering because his father needed help on the farm.
2.避免频繁使用“there be”结构，例如下面的句子：
There were 25 cows on the farm that my grandfather had to milk every day. It was hard work for my grandfather.
可以改为：
My grandfather worked hard. He had to milk 25 cows on the farm every day.
更简洁的句式为：
My grandfather worked hard milking 25 cows daily.
3.把从句改为短语或单词。例如：
Dairy cows were raised on the farm, which was located100 kilometers from the nearest university and was in an area that was remote.
简介的表达方式为：
The dairy farm was located in a remote area, 100 kilometers to the nearest university.
4.仅在需要强调宾语而不是主语的时候，才使用被动语态。例如：
In the fall, not only did the cows have to be milked, but also the hay was mowed and stacked by my grandfather's family.
本句不够简洁的原因是本句的重心应该是“忙碌的家庭-my grandfather's family”，而使用了被动语态后，仿佛重心变成了cows和hay。下面的表达方式是主动语态，相对来说更简洁一些：
In the fall, my grandfather's family not only milked the cow but also mowed and stacked the hay.
