雅思寫(xiě)作句型分析：狀語(yǔ)前置

　　狀語(yǔ)前置就是把一個(gè)修飾動(dòng)詞的狀語(yǔ)結(jié)構(gòu)，如介詞短語(yǔ)，分詞形式或動(dòng)詞不定式引導(dǎo)的短語(yǔ)放到句首。請(qǐng)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(yǔ)前置的最大優(yōu)點(diǎn)是讓單調(diào)的句子有了跳躍的節(jié)奏感?？脊僖惶炜瓷习?gòu)埧季?，看到這樣的句子也會(huì)心情愉悅。

　　注意：插入語(yǔ)

　　此種語(yǔ)法結(jié)構(gòu)是可以理解為是狀語(yǔ)前置的另一種變體，它將狀語(yǔ)結(jié)構(gòu)提到了主句的主語(yǔ)和謂語(yǔ)之間。插入語(yǔ)也是相對(duì)地道的英語(yǔ)表達(dá)方法。請(qǐng)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(yǔ)的功能和狀語(yǔ)前置基本相似，都能使句子更有跳躍感和地道。
