用法讲解

adv. (副词)
  1. as用作副词时主要用来表示比较,意思是“像…一样；如同”。可以单独使用，但更多的是用在as...as结构中，其中第一个as是副词，其后可接形容词或副词,也可接其他成分，as前可有状语。第二个as可以是介词,也可以是连词。as用作副词时还可以指事物以同样的方式发生,意思是“和…一样”。
  2. as...as结构多用于肯定式，偶尔也可用于否定式。表示同样意思的否定式多用so...as。as...as结构用于否定句时多用于口语，侧重“像…一样”；so...as结构则多用于书面语，侧重“像…那样”。
  3. as...as结构表示的是同级比较，第一个as后的形容词或副词不可用比较级，必须用原级，比较的对象亦须属同类。
  4. as...as结构表示数量或程度时，可用于“as much+(不可数名词+) as”或“as many+(可数名词复数+) as”结构。
  5. 修饰as...as结构的常见词语有nearly,almost,just,exactly,half,quite,表示倍数或次数的形容词，“数词+times”等。这些修饰语都放在as...as结构之前。
  6. 使用as...as结构时，若第一个as后的名词是单数可数名词并有形容词修饰，则应使用“as+ adj.+ a/an+ n. ”结构，即不定冠词应位于形容词和名词之间。第二个as后面的名词或代词的格不同，意思也不同。
  7. as...as结构中后一个as用作连词时引导的从句常为省略句，省略从句中的动词可使主句的意义得到加强；反之，重复从句中的动词则可使从句的意义得到强调。
  8. 使用as...as结构时，在一定的上下文中可以省去其中的一个。
  9. as用作副词时不用于比较等级。
prep. (介词)
  1. as作“以…的身份,以…资格,作为，以…角色”解时常与动词act,employ,function,serve,speak,work或形容词eminent,distinguished,famous,known,recognized,renowned等连用。
  2. as比较常用于as...as和the same...as两个句型。
conj. (连词)
  1. as用作连词时,可以用来表示时间,译为“正当…的时候;随着…;边…边…”,引导时间状语从句。主句可以是主动句,也可以是被动句。当两个主语的动作是同时发生的时候,主句和从句的谓语动词都可以用进行时态或一般式,无论动作长短;当两件事发生的时间间隔很短,甚至没有时间间隔时,主句和从句均用一般过去时;当主句的动作发生在从句的动作发生的过程中的时候,主句和从句可以都用一般过去时,也可以在从句中用进行时态。当表示两个动作的完成时间恰好一致时,as连接的主、从句也都可用过去完成时。
  2. as还可表示原因,作“因为,既然”解，引导原因状语从句，表示不说自明的原因或理由，语气较轻，是附带提及，不加强调。as引导的从句可放在主句之前(表示原因不明显),也可放在主句之后(表示原因明显)。
  3. as可表示让步,作“尽管”解,引导让步状语从句。当主句的谓语动词是be或其他系词的限定形式时,常用于“名词〔形容词,过去分词〕+as+主语+be〔其他系词〕”的限定形式（名词位于句首时一律不用冠词）;当主句的谓语动词是行为动词时,常用“副词+as+主语+行为动词(+其他附加成分)”的形式。有时也把动词放在从句句首，尤其是有may,might,will,would等情态动词时。注意当主语是名词时常用倒装语序，主语是代词时则不用倒装语序，主语位于谓语之前。
  4. as可以引导一个比较关系的状语从句,意思是“像…一样”;为了加强比较的意味,主句中常加副词as（用于肯定句）或so(用于否定句)。此时as可用于“as...as...can〔could〕 be”结构，用来强调形容词的含义，一般可译为“到了…的程度”“极其”。
  5. as可以引导方式状语从句,意思是“依照,按照”。
  6. as引导比较或方式状语从句时，从句一般采用正常语序，但在正式语体里，也采用倒装语序，但不是强制性的。
  7. as还可用于插入语，可置于句首、句中或句末，并常有逗号与句子的其他成分分开。
  1. as 常做关系代词，如such children as love their books中的as是love的主语。such books as are loved by children中的as是are loved的主语，所以要分析清楚句子结构，不可以随便删除谓语动词，如上句中的are。当as指代主句所讲述的内容时，也做关系代词。值得注意的是，as在作关系代词时，极易被误认为是连接词而加用it。

    As is announced in today's papers, all the schools will reopen on 1 September.
    句中的as指学校将在9月1日重开这件事。

    As it is announced in today's papers, all the schools will reopen on 1 September.
    句中的it是多余的，不该加。

  2. as much/many ...中as用来谈论数量。另外as much/many可作为代词，后不接名词。同时，as much ...可作为副词。

    I haven't got as much money as I thought.
    我带的钱没有我自己想象的那么多。

    I ate as much as I could.
    我尽可能得多吃。

    You ought to rest as much as possible.
    你应该尽可能多地休息。

  3. as ... as ...指“两个人或物在某方面一样”，既可以用在肯定句里，也可以用在否定句中，而so ... as ...只能用在否定句里。“as ... as ...”有时含有第二个as后的主语有着高程度的那形容词（或副词）所指的特点，如上述例句中有暗指“她很老”。用isn't，wasn't，don't和can't等时，多习惯与as搭配，而不是so，如He isn't as old as she (is)比He isn't so old as she (is)更为普遍。若是句中的形容词或副词前用了 quite这个词时，就习惯不用as，用so。

    He is as old as she (is).
    He is not so old as she (is).

    He isn't quite so old as she (is).

  4. as在表示“原因”时，语气要轻于because。一般来说，as引导的从句会在主句前。as引导的从句也可以在主句后，不过必须要确认从句的内容要是对方知道的。注意在表示原因时，不可以把as和so连用，两者只能存在一个。 不过as ... so ...的表达方式是可以的，但指“正像……，……”。

    You need not go with me, as you are busy.
    可以说，因对方知道自己忙。

    I cannot go with you, as I am busy.
    应该避免使用，应对方不一定知道我很忙。

    As you like music, so I like poetry.
    正像你喜欢音乐一样，我喜欢诗歌。

  5. as还可指“虽然”，如beautiful as she，（虽然她很漂亮）和child as he is（虽然他很孩子气）。这样用时，要注意格式上形容词或名词在as前以及名词前没有a或an；
  6. as也可加副词或动词。

    Much as I should like to see you, I am afraid you may find it inconvenient to come in this hot weather.
    Search as they would, they could find nobody in the house.

  7. 要注意区分so ... as和so ... that，such ... as和such ... that，彼此之间不可以互相替换。

    Here is so big a stone as no man can lift.
    习惯上，虽然as和that都可做关系代词或链接词，但使用that时，要与it搭配使用，而as要单用，不可以搭配it使用。

  8. as指“当…的时候”时，引导的从句中的动词不能以将来时呈现。

    Count the children as they will enter the room.
    句中的will应该删掉。

  9. so ... as to ...（不定式）同…enough to ...（不定式）表达的意思相同。

    Write so carefully as to make every sentence clear.
    注意这两个结构是固定的搭配。

  10. as from指“从某日开始”，常用在法律，契约，公告的文件中。

    The shopping center will be open to the public as from 6 May, 2001.
    商场会从2001年5月6日起重新开业。

  11. as well as指“（除……之外）也，又”，要注意它同and和not only ... but (also)...是有区别的。A as well as B = not only B but also A，指“不单B，而且A”，注意是B在前，A在后。不可以用A，B，as well as C.通常来说，as well as作连接词，不是介词。结构“both ... as well as ...”是错误的，避免使用。常有人用“not only ... but ...as well”的结构，同“not only ... but also …”或“not only ... but ...”表达的意思相似，但是没有后者使用普遍。

    He is a Chinese, but he has foreign friends as well as Chinese friends.
    第一句是正确的表达，第二句是错误的。

    I read French, German, as well as English.
    这个句子是不可以的，应用and来连接。

    He advised me as well as answering my question.
    句中把as认作是介词，接了动名词answering，实际上是错误的，应改为answered。

adv. (副词)
下面各组中句子的意思不同:
  • They love him as much as she.
  • 他们和她同样爱他。
  • They love him as much as her.
  • 他们爱他，也同样爱她。
  • 约翰和鲍勃一样有礼貌。
  • John is as polite as Bob.
  • (强调约翰有礼貌)
  • John is as polite as Bob is.
  • (强调鲍勃有礼貌)
    • prep. (介词)
    as, for
  • 这两个词均可作“作为；当作；用作”解,一般情况下可以互换。但as表示资格，而for表示用途。例如：
  • She was respected as a teacher.
  • 作为一名教师，她受到尊敬。
  • She won't do for a teacher.
  • 她做教师不行。
  • 另外，在regard,think of,treat等动词之后一般用as,不用for。
    • as, like
  • 这两个词的区别是：
  • 1.在作“如”“像”解时，as可用作连词，引出方式状语从句；而在正式英语中like不能这样用，只能用作介词。例如：
  • 请尽量按我这样写。
  • Please try to write as I do.
  • Please try to write like me.
  • 作为学生，应试时须严格按照上述规定作答，但实际上在非正式的英语里，like用作连词还是很常见的。例如：
  • I can't sing like I used to.我不能像以前那样唱歌了。
  • 2.as和like都可用作介词，但意义不同。as用于人时强调其身份、职业、地位、角色等,指物时侧重其作用、功能等;like则强调人或事物的外貌特征和性格特征的相像,或行为方式的相同。简言之，as表示一种事实，即“是”;而like则表示一种比喻，即“像”。例如：
  • She spoke as a lawyer.
  • 她作为律师发言。
  • She spoke like a lawyer.
  • 她讲话很像是律师。
  • 3.表示动作方式一般用like。例如：
  • 他吃起东西来像头野兽。
  • ［误］ He ate as a beast.
  • ［正］ He ate like a beast.
  • 4.表语词组一般由like引导,而不用as引导。
    • conj. (连词)
    as a matter of fact, as good as, as it is
  • 这三个短语都有“实际上，事实上”的意思，其区别是：
  • as a matter of fact含有对比之意,说的是与已知的或已说过的内容不同的内容；as good as没有对比的意味，意思是“实质上差不多等于”；as it is则用于指出即将说的是一个事实。例如：
  • Mike said he didn't tell a lie.As a matter of fact, he did.迈克说他从没有说过谎。事实上,他说过。
  • He as good as refused.他实际上等于拒绝了。
  • We had hoped to finish today,but as it is we probably won't finish until tomorrow.我们原本希望今天能做完它，但实际情况是我们或许要等到明天才能做完。
    • as, because, for, since
  • 这四个词都可以作连词引导一个表示原因的状语从句。其区别是：
  • 1.because是从属连词,引导的原因状语从句指的是自然、直接的原因,主句表示必然的因果关系,而原因构成句子的主要部分,是句子的重点。另外,because引导的从句多放在句末,但有时也可放在句首,这种情况往往是为了强调。
  • 2.如果原因很明显或已为人们所知,或不如句子的其余部分重要,就用as或since,since比as更正式一些,这两个词都为从属连词,常译为“由于,既然”,语气比because轻。as和since引导的句子多放在整个句子的开头,偶尔它们引导的(特别是since引导的)句子也可以放在后面。since作为理由有“不好”或“勉强”的含意;而as只将既成事实作为理由,并不含有“不好”或“勉强”的意味。
  • 3.for是并列连词,引导的是并列从句,表示原因的语气很弱,一般是对结果作推断性的补充说明或解释,不表示直接原因。for较正式,很少用于口语,一般用于书面语,前面一般多用逗号。
    • as it is/was, as it were
  • as it is/was是个短语，意思是“实际上”“事实上”“照目前情况来看”，用于把可能的情景与实际发生的情况进行对比；而as it were的意思则是“可以说是”“似乎是”“仿佛”，表示所说的话听起来不那么肯定。
    • as, though
  • 这两个词用作从属连词引导让步状语从句时，都可采用倒装语序。其区别在于：as采用这种倒装语序是强制性的，而though则是非强制性的。此外，as引导的这种倒装语序还可表示原因，而though则无此功能。
    • as, when, while
  • 这三个词都可作连词引导一个表示时间的状语从句。as引导的从句作“当…时”或“和…同时”解,从句中的动作与主句中的动作同时发生或同时进行,一般持续时间不长;when引导的从句作“当…时”或“每逢…”解,从句中的动作既可以和主句中的动作同时发生,也可以在主句的动作之前或之后发生;while引导的从句作“当…时”或“在…期间”解,它强调从句中的动作与主句中的动作同时发生,但持续时间一般较长或主句的动作在从句的动作过程中发生。while与as和when的最大区别在于有时含有“趁着…情况的存在赶紧做某事,否则来不及了”的意味。
    • as well, also, besides, either, moreover, too
  • 这组词(组)都有“也,此外,还有”的意思。其区别是：
  • also一般用于肯定句,有强调意味,位于主谓语之间,即实义动词之前,助动词之后; too只用于肯定句中,一般位于句末,比also更口语化; either一般只用于否定句,多位于句末; as well和too一样多用于口语,放在句末; besides与moreover词义基本相同,但moreover后面所叙述的,通常比前面所叙述更为重要或更深入一步,在词序方面, moreover往往用于句首,另外, moreover是较为正式的用语。例如:
  • He also asked to go.他也要去。
  • I can also do it.我也能干那个活。
  • English is not easy, and French is not easy either.英语不容易,法语也不容易。
  • He is a teacher, and a writer as well.他是个教师,也是个作家。
  • I don't like those shoes; besides, they're too expensive.那双鞋我不喜欢,而且也太贵。
  • I don't like skating; moreover, the ice is too thin.我不想去溜冰,再说冰层也太薄。
  • The Opposition have consistently accused the Government of corruption.Moreover, they have named names.反对党一直在指责政府腐败,而且是指名道姓的。
    • 下面两个句子的意思不同:
  • We have a third as many students in our class as we had last term.
  • 我们班的学生是上学期的三分之一。
  • We have a third as many students again in our class as we had last term.
  • 我们班的学生比上学期多了三分之一。
    • as，because，for，since
  • 这些连词均含有“因为”之意。
  • as从属连词，语意较because, since弱，着重在主句，所表示的原因或理由是“附带的”。
  • because从属连词，语意强，着重直接的原因或理由，所引出的从句是全句的重心，用以回答why提出的问题。
  • for并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。
  • since语意比because弱，但比as强，一般用于表示“由于大家已知的事实”。
    • as，like
  • 这两个词均有“像”之意。
  • as从属连词，引出方式从句。
  • like是前置词，后面跟的是宾语。
    • though，although，as，even though
  • 这些连词均可表示“虽然，尽管”之意。
  • though和although在意义上几乎毫无区别，但在习惯用法上这两个词仍有以下一些差异：1.though可引出倒装语序的让步状语从句，although 则不能。2.though可与even连用，although则不能；在as though结构中，只用though，不能用although。3.though可以置于从句末，而although则不能。4.引出省略句时，通常用though。
  • although与though在意义上相似，但文体上是比较正式用词，语气比though强。
  • as引出让步状语从句只用于倒装语序结构中，语气强于上述两个连词。
  • even though（＝even if），意为“即使”，引导让步状语从句。though也引导让步状语从句，意为“虽然”；even though有退一步设想的意味，与though不同。though引导的句子所说的是事实，even though引导的句子所说的则不一定是事实。例如：
    • when，while，as
  • 这些连词均可表示“当……时”引出时间从句。
  • when所引导的从句，其谓语动词既可是持续动词，也可是短暂动词；谓语动词动作发生的时间可以与主句谓语动词的动作是同时，或之前、之后。
  • while句中的谓语动词应为持续动词，不用短暂动词，谓语动作发生的时间通常与主句谓语动词动作发生时间是同时。
  • as侧重指从句与主句的动作同时进行，谓语动词可以是持续性的，可以是短暂性动词。

    • 常见错误

    adv. (副词)
      她像她母亲那样慈善。

      误 She was kind as like as her mother.

      正 She was as kind as her mother.

      误 This piano is equally as good as that one.

      正 This piano is as good as that one.

      正 These two pianos are equally good.

      析 介词like和副词equally同as的词意相同，不能同时出现在一个句子中。
