雅思小作文常用句型的作用：一方面，使用常用句型能夠提高文章的連貫性，幫助考生在有限的時間內(nèi)完成任務(wù)；另一方面，常用句型能夠幫助考生在語言表達方面達到一定的水平，讓文章更加流利，自然。

常用句型的分類：首先，需要明確的是，常用句型的分類并不是唯一的，以下僅供參考：

1. 表達事實：as far as … is concerned; it is well known that…

2. 表示行程：first and foremost; initially; above all

3. 對比觀點：although; despite; however

4. 引用作者觀點：according to x,…; in x's opinion

5. 明確表達: undoubtedly; obviously; certainly

需要注意的是，為了避免反復(fù)使用同一種句型而被扣分，考生還需要掌握相應(yīng)句型的替換。

常用句型的注意事項：首先，考生需要靈活運用常用句型，避免過度使用而影響整體質(zhì)量；其次，應(yīng)根據(jù)不同的題目要求選擇相應(yīng)的句型。
