AS用法总结【第五篇】
一、用作连词的as
1. 引导时间状语从句,表示“当……的时候”,其用法与when和while类似。例如:As a child (When he was a child), she was sent to six different schools.此用法中as多表示从句与主句动作同时进行,意为“一边……一边……”,一般不与状态动词连用。例如:She sang songs as she did her homework.
as 还可以表示一动作紧接着另一动作发生,说明另一动作的结果,有“随着……”的含义。例如:As time went by, we found he was an honest man./As he grew older, he lost interest in everything except gardening.
例1 It wasn’t until nearly a month later________ I received the manager’s reply.
A. since B. when C. as D. that
解析:本题的as中与when一起作为干扰项,容易使考生往时间状语从句上思考,事实上本题是强调句,正确选项是D。
2. 引导原因状语从句,表示“由于,因为”,相当于because, 但通常置于句首。例如: As he is a qualified doctor, I trust his advice on medical matters.
例2 _____ modeling business is by no means easy to get into, the good model will always be in demand.
A. While B. Since C. As D. If
解析:本题中as干扰性很强,很多考生误以为是原因状语从句,但仔细分析不难发现正确答案应是A(while表示“只要”)。
3. 引导让步状语从句,通常可与although或though通用,但语序不同,although或though用于句首,as用于倒装结构。例如:Young as I am, I already know what career I want to follow. /Although(或Though)I am young, I already know what career I want to follow. as 表示让步用于倒装结构,通常将从句的表语、状语或动词前置。如果表语有冠词a/an, 需去掉。例如:Great scholar as he is, he is lacking in common sense./Much as I like you, I couldn’t live with you. 例3 _____ he has limited technical knowledge, the older worker has a lot of experience.
A. SinceB. Unless C. As D. Although
解析:as 虽然有引导让步状语从句用法,但本题不是倒装结构,故正确答案应是D。
4. 引导方式状语从句,表示“如,像”。例如:When in Rome, do as Romans do./Do to others as you would have others do to you.
例4 We wanted to get home before dark, but it didn’t quite ________ as planned.
A. make outB. turn out C. go onD. come up
解析:本题考查动词词组辨析,题干中的“as planned”给同学们提供了重要信息,答案选B。
5. 固定句型:“主句,as +be/do+主语”表示“也一样”。例如:She’s unusually tall, as are both her parents./He’s a doctor, as was his wife before she had children.
二、用作介词的as
1.表示“如,像”。例如:They got united as one man./She spoke of me as her dearest friend.
2.表示“作为、当作”。例如:As a League member, you should think more of others.
3.与某些动词搭配,表示“把……当作……”,如:look on…as…, regard…as…, treat…as…, consider…as…, think of…as…, see…as…等。其中consider…as…中的as可以省略。as与famous或known搭配,表示“作为……而出名”。
例5 Linda worked for the Minnesota Manufacturing and Mining Company, ________ as 3M.
A. knowingB. known C. being knownD. to be known
解析:如果熟悉be known as这一短语,运用有关非谓语动词的常识,可选出正确答案B。
三、用作关系代词的as
1. 引导限制性定语从句,先行词前通常有as, so, such, same等修饰语。例如:He will marry as pretty a girl as he can find./My hometown is no longer the same as it used to be./As many people as are present will be given a present.在此种用法中,同学们要注意与结果状语从句的区别。比如:A: The teacher asked us such a difficult question that none of us could answer it. B: The teacher asked us such a difficult question as none of us could 句为结果状语从句,而B句则是定语从句。
2. 引导非限制性定语从句,用来指代整个主句(即先行句),表示“这一事实,那一情况”。从句可以位于句首、句中或句末。例如:We stand when the national anthem is played, as is the custom.
例6 ______ I explained on the telephone, your request will be considered at the next meeting.
A. When B. After C. As D. Since
解析:根据句意,选项C是正确答案。as表现的正是本点所讲用法。
四、用作副词的as
修饰形容词或副词,表示程度,意为“同样地”。例如:He swims fast, but I swim just as fast. 但它通常构成表示比较的结构“as„as„”,“not as„as„”。此结构中第一个as是副词,第二个as是连词。否定结构中的副词as可以由so代替。as„as possible /one can也属于此用法。例如:It is generally believed that teaching is as much an art as it is a science.
五、用在习语中的as
由as构成的习语很多,常见的有:as soon as “一„„就”,引导时间状语从句;as/so long as “只要”引导条件状语从句;as if/though “好像,仿佛”,引导方式状语从句或表语从句;as to/ as for “至于,就„„而言”;as much/many as“多达„„”;as/so far as “就„„的限度”;as a result,as a result of “(由于„„的)结果”;as a matter of fact“事实上”;as well “也、还”;A as well as B“不但A而且B”;as it is“照现状看,看样子”,等等。这些习语在高考中可能经常遇到,在高考题中有的作为正确选项,有的作为干扰项,有的出现在题干,值得同学们认真掌握。例如:
例9 I would like a job which pays more, but ______ I enjoy the work I’m doing at the moment.
A. in other wordsB. on the other hand C. for one thing D. as a matter of fact 解析:选项D极具干扰意义,但进一步研读会发现本题中的两个分句表达了一件事的两个对立面,故选B。
例10 ——People should stop using their cars and start using public transport. ——______. The roads are too crowded as it is.
A. All right B. Exactly C. Go aheadD. Fine
解析:本题选项中虽没有as内容,但题干中的as it is却是解题的关键信息,正确选项为B。
以上所总结的是as一词的主要用法及在高考卷中的具体应用,可以看出它词性多,词义广,用法灵活。龙文学校辅导教师希望同学们在复习中一定要理清思路,抓住重点,应用时仔细分析上下文,弄清逻辑关系,才能作出正确选择。
