雅思寫作中的三個高頻語法知識點

　　1、狀語前置 狀語前置就是把一個修飾動詞的狀語結(jié)構(gòu)，如介詞短語，分詞形式或動詞不定式引導(dǎo)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(jié)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(yōu)點是讓單調(diào)的句子有了跳躍的節(jié)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。

　　2、插入語　此種語法結(jié)構(gòu)是可以理解為是狀語前置的另一種變體，它將狀語結(jié)構(gòu)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(dá)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.

　　插入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。

　　3、倒裝句　這種語法現(xiàn)象相信很多朗閣的學(xué)員都學(xué)過，即把謂語提前到主語之前，用在作文中比較新穎。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.
