    1. 时间状语从句中as = while 表示during the time.接延续动词

    2. 原因状语从句中as = since 人们已知的事实,不需要强调的原因。

    3. 目的状语从句so that = so as to

    4. 结果状语从句简化, such...that = such...as to so...that = so...as to such that = such as to

    5. 让步状语从句的倒装:

      image
    • 动词原型置句首

      • 结构为:v. + as + 主语 + 助动词may,might,will,would,can,could,do,does,did) Fail as I did,I would never stop trying.尽管我失败了,但我决不会停止尝试。 Try as he will,no man breaks wholly loose from his first love,........

      • 若动词是及物动词,则宾语也随着动词提前: Lose money as I did,I got a lot of experience.尽管我费了不少钱,但是获得了很多经验。

      • as可以替换为that或though,尽管较少这样用,不可以用although。 Odd though it sounds,cosmic inflation is a scientifically plausible consequence of some...(though代替as来表示让步)

    • as/so + 形容词 + as + 主谓结构,放在句首表示让步(较少见As much as john hates to do it,he must stay at home and study tonight.尽管约翰不愿意,但他今晚还得待在家里学习。 As amusing and perceptive as graffiti may sometimes be, it has by no means won universal approval.尽管涂鸦有时可以怡人情趣并发人深思,但它决不会赢得普通的认同。

    1. 比较状语从句:

      • as + 形容词或副词 + as

      • as + 形容词 + a(n) + 可数句词单数 + as

      • 否定句中的第一个as可用so代替。

      • 为了保持句子平衡,从句还可以用倒装结构as...as + 助动词 + 主语

      • as句型一:as much as结构

      • as句型二:not so much...as结构

      • as句型三:(just)as...,so结构

      • A is to B what/as C is to D结构

    2. 方式状语从句

      • as引导方式状语从句

      • as引导方式状语从句可倒装

      • as的特殊用法:用于否定结构

        • as前面句子是否定的,as所在的句子本身是肯定的。(as译为“不像”)

        • as前面句子是肯定的,as所在的句子本身是否定的。(as译为“但,然而”)

    3. 引导定语从句

      • as引导非限定定语从句时,可放在句中,句前,句末。

      • as引导限定定语从句,必须是固定词组一起使用:such...as,as...as,the same...as
