目前2013考研備考正當時，英語語法中AS結構和比較結構是考研英語最常出現的語法點之一，也是考生的弱點，為了方便大家的學習，新東方在線網絡課堂考研輔導團隊特將考研英語語法中AS的用法及考點總結如下，希望對大家的複習有所幫助。
1、as用作固定短語

G． as to 關於, 至於

H． as well as adv. 也, 又
98年74題： If the small hot spots look as expected, that will be a triumph for yet another scientific idea, a refinement of the Big Bang called the inflationary universe theory.
詞義推敲 ：
the small hot spots 小熱點
refinement 更完美，提煉，改進
the inflationary universe theory 宇宙膨脹說(理論)
look as expected 看上去與預計的一致」。
Triumph=victory or conquest 勝利，得勝勝利的事實，勝利或徵服
refinement 更完美，提煉，改進
called：作後置定語，譯作「所謂的……」，「人們稱之為……」
the inflationary universe theory 宇宙膨脹說（理論）
參考譯文：假如那些小熱點看上去同預計的一致，那就意味著又一科學論說的勝利，這種論說即更完美的大爆炸論，亦稱宇宙膨脹說。
2、翻譯為「作為」
2005年text 4
As a linguist, he acknowledges that all varieties of human language, including non-standard ones like Black English, can be powerfully expressive-there exists no language or dialect in the world that cannot convey complex ideas.
參考譯文：做為一位語言學家，他承認各種語言，包括那些非標準的語言，比如黑人英語，都具有極強的表達力--世界上任何語言或是方言都能傳達複雜思想。
3，as…as …和…一樣
99年71題：While there are almost as many definitions of history as there are historians, modern practice most closely conforms to one that sees history as the attempt to recreate and explain the significant events of the past.
參考譯文：儘管每一位歷史學家都有自己對於史學的定義，現代實踐最接近符合這樣一個定義，這個定義把歷史看作是重新創造和解釋過去重要事件的嘗試。
4、not so much…as… 與其說…不如說是...
94年71題：Science moves forward, they say, not so much through the insights of great men of genius as because of more ordinary things like improved techniques and tools.
他們認為，科學之所以向前發展，與其說是因為天才偉人的洞察力還不如說是因為像改進了的工具和技術那些更為普通的東西。
最後，新東方在線網絡課堂考研輔導團隊祝大家備考順利！
