雅思寫作高分語法結構分析
1. 狀語前置
狀語前置就是把一個修飾動詞的狀語結構，如介詞短語，分詞形式或動詞不定式引導的短語放到句首。雅思寫作中狀語前置是很拿分的句式，不過很多考生都沒意識到這一點。
請看下面從劍橋提供的范文中節選的句子：
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。
使用狀語前置的最大優點是讓單調的句子有了跳躍的節奏感。考官一天看上百張考卷，看到這樣的句子也會心情愉悅。
注意：插入語
此種語法結構是可以理解為是狀語前置的另一種變體，它將狀語結構提到了主句的主語和謂語之間。插入語也是相對地道的英語表達方法。請看以下幾例：
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。
語的功能和狀語前置基本相似，都能使句子更有跳躍感和地道。

2. 倒裝句
我們先來看以下幾個例子：
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。
以上兩句話都沒有任何錯誤，但是讀來非常平淡，沒有任何特色，如果我們用倒裝句，出來的效果就完全不一樣了。
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。
當然在平時教學和備課的過程中我們還是要不斷積累各式各樣的倒裝句句式進行替換，靈活運用。

3. 強調句
It is… that… / It is… who…正是…導致了
以下是考官寫的一句話：
1. It is the interaction of the two that shapes a person‘s personality and dictates how that personality develops。
強調句是考生比較難把握的一種句型，容易和it引導的形式主語相混淆，但其實我們只要找到強調句的一個特點，即去掉It is… that… / It is… who…仍然是一個完整的句子。
通過以上三種句式結構的介紹，考生就能輕松給簡單句穿上外衣進行包裝了，這樣表達同樣的意思用不同的句式結構，出來的效果完全不一樣。在筆者平時在朗閣課堂的教學中，這幾個句型幫助學生突破了如何寫好句子的瓶頸。下面我們來看一句話分別用不同的三種表達方法，明顯改變了效果。
