as詞雖小，本事可不能小瞧。本文就as要點(diǎn)進(jìn)行歸納，便于學(xué)生全面掌握。首先，為了便于記憶，請(qǐng)欣賞as口訣：as用法何其多，介詞連詞都包括，介詞as是作為，連詞as得細(xì)說，正如正像表因果，一邊一樣加隨著，雖然as要倒裝，時(shí)間as有省略，固定結(jié)構(gòu)要牢記，學(xué)好as上大學(xué)?，F(xiàn)在，我們分別從介詞和連詞的角度來復(fù)習(xí)as的用法。

一、as用作介詞，常與一些動(dòng)詞或介詞構(gòu)成固定搭配

act——as（扮作）consider——as（把…看作）describe——as（把…描述成）look on——as（把…看作）regard——as（把…看作）remember——as（作為…記?。﹕erve/work——as（擔(dān)任；充當(dāng)）see——as（把…看作）think of——as（把…看作）treat——as（把…看作）regard...as（把…看作）use——as（用作）such as（例如）as usual（像往常一樣）as for（至于；關(guān)于）as with（正像…一樣）as good as（和…一樣好；實(shí)際上）as long as（和…一樣長；只要）as far as（和…一樣遠(yuǎn)；就…所知）as well as（和…一樣好；也；又）as soon as（一…就）as many/much as（多達(dá)）so as to do s th（為了做某事）

5.She is such a kind girl as everybody likes.

6.This is not as hard a question as that one.

三、as用作連詞，引導(dǎo)并列句

四、as用作連詞，引導(dǎo)時(shí)間狀語從句
