2016考研英語復(fù)習(xí)：AS用法大揭秘(上)

　　在考研英語中，比較讓大家鬧心的是長(zhǎng)難句，但只要找出主干、理清成分也沒有那么難以對(duì)付。相反，有一些小詞，用法繁多，在不同句子中需要辨別出真正的意思就沒那么簡(jiǎn)單了，今天文都網(wǎng)校考研英語靖老師就as詞性的相關(guān)用法給大家進(jìn)行梳理。

　　從詞性來看，as主要有介詞、連詞、關(guān)系詞。當(dāng)as作為介詞時(shí)，往往與動(dòng)詞搭配，形式為V...as...,這時(shí)動(dòng)詞就不要使用本意，而是統(tǒng)一翻譯為將A視為B;把A看成B,在考研英語中出現(xiàn)的動(dòng)詞總結(jié)如下：see/view/regard/consider/identify/define/classify/

　　interpret/dismiss/elect/accept/think of A as B.除了這些簡(jiǎn)單的詞語外，當(dāng)賓語A復(fù)雜時(shí)會(huì)后置于B，形式如下: v. as B A。我們來看一句話On the other hand he did not accept as well founded the charge made by some of his critics that while he was a good observer he had no power of reasoning.動(dòng)詞是accept，介詞是as，as后直接跟的賓語B(形容詞),A由于復(fù)雜后置到了B后，是the charge,后跟一系列的定語-made by some of his critics以及同位語-while he was a good observer he had no power of reasoning，這句話是說另一方面，他認(rèn)為一些批評(píng)者的指控沒有根據(jù)，指控內(nèi)容是說雖然他是個(gè)好的觀察者，但他沒有推理能力。

　　當(dāng)as作為連詞時(shí)，可以表時(shí)間：隨著....../當(dāng)......時(shí)候(一般位于句首)。例句如下：As funding for science has declined, scientists have attacked "anti-science" in several books.隨著用于科學(xué)的資金減少，科學(xué)家在一些書中攻擊“反科學(xué)”論調(diào)。可以表原因：既然、由于=since。例句如下：We are obliged to them because some of these languages have since vanished, as the peoples who spoke them died out or became assimilated and lost their native languages.我們感激他們，是因?yàn)橐恍┱Z言自此以后消失了，消失是由于這些語言使用者已經(jīng)死去或者被同化，進(jìn)而失去了他們本族語言�？梢员碜尣剑罕M管、雖然，(as一定不能位于句首，位于句中第二個(gè)詞)。例句如下：

　　In addition, difficult as it is to believe, there are desert fish which can survive through years of drought in the form of inactive eggs.另外，盡管很難相信，確實(shí)存在沙漠魚，這些魚以不活躍卵的形式在干旱中存活數(shù)年。可以表比較，as...as + 詞/句子：和...一樣、像...一樣;not so......as + 詞/句子：和...不一樣、不像...那樣;not so much...as...:與其說...不如說...�？梢员矸绞剑�等于in the way that,按照、正如。

　　As作為關(guān)系詞時(shí)，引導(dǎo)限定性定語從句：先行詞前有such/the same;非限定性定語從句：修飾整個(gè)句子，比如As is known to all, ...;..., as is often the case;...,as you know,...。

　　以上是關(guān)于as的詞性及用法梳理，接下來會(huì)在具體的例子中給大家進(jìn)行講解，以加強(qiáng)理解。希望大家能夠通過這次課程，把a(bǔ)s的用法掌握住，祝大家考研英語復(fù)習(xí)愉快、考研順利。
