1. 状语前置
状语前置就是把一个修饰动词的状语结构，如介词短语，分词形式或动词不定式引导的短语放到句首。雅思写作中状语前置是很拿分的句式，不过很多考生都没意识到这一点。
请看下面从剑桥提供的范文中节选的句子：
1) Like self-awareness， this is also very difficult to achieve， but I think these are the two factors that may be the most important for achieving happiness.
2) Throughout the century， the largest quantity of water was used for agricultural purposes.
3) With a population of 176 million， the figures for Brazil indicate how high agricultural water consumption can be in some countries.
使用状语前置的最大优点是让单调的句子有了跳跃的节奏感。考官一天看上百张考卷，看到这样的句子也会心情愉悦。
注意：插入语
此种语法结构是可以理解为是状语前置的另一种变体，它将状语结构提到了主句的主语和谓语之间。插入语也是相对地道的英语表达方法。请看以下几例：
1) Universities， when it is functioning well， should offer both theoretical knowledge as well as professional training.
2) So overall， I believe that， attending school from a young age is good for most children.
语的功能和状语前置基本相似，都能使句子更有跳跃感和地道。

2. 倒装句
我们先来看以下几个例子：
1) The parents should spend time on their children， they should also communicate with them.
2) We can never lose sight of the significance of education.
以上两句话都没有任何错误，但是读来非常平淡，没有任何特色，如果我们用倒装句，出来的效果就完全不一样了。
1) Not only should parents spend time on their children， they are also advised to interact with them.
2) On no account / by no means / in no way can we lose sight of the significance of education.
当然在平时教学和备课的过程中我们还是要不断积累各式各样的倒装句句式进行替换，灵活运用。

3. 强调句
It is… that… / It is… who…正是…导致了
以下是考官写的一句话：
1. It is the interaction of the two that shapes a person‘s personality and dictates how that personality develops.
强调句是考生比较难把握的一种句型，容易和it引导的形式主语相混淆，但其实我们只要找到强调句的一个特点，即去掉It is… that… / It is… who…仍然是一个完整的句子。
通过以上三种句式结构的介绍，考生就能轻松给简单句穿上外衣进行包装了，这样表达同样的意思用不同的句式结构，出来的效果完全不一样。在笔者平时在朗阁课堂的教学中，这几个句型帮助学生突破了如何写好句子的瓶颈。下面我们来看一句话分别用不同的三种表达方法，明显改变了效果。
