状语前置是很多同学很难弄懂的一个语法状态，那么不懂的同学们今天就和出国留学网来看看雅思写作状语前置。
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。请看下面的句子：
（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.
插入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。
