雅思寫作句型分析：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。請看下面的句子：

　　(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.

　　使用狀語前置的最大優(yōu)點是讓單調的句子有了跳躍的節(jié)奏感?？脊僖惶炜瓷习購埧季恚吹竭@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.

　　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。
