在英语学习中,"as"作为一个词性多,词义广,出现频率高的词,是六级考生必须熟练掌握,并且应该能够正确加以运用的重点词汇。这里,结合例句,着重列举一些常用的,以及在考试中经常出现的短语及用法。

1. as do I /as I do
a)He writes as his father did.他像他爸爸一样写作。

注:表示比较或方式的as从句一般使用正常语序。但是,在正式语体中,也可以采用倒装,但不是强制性的,而是选择性的。例如:

b)She looks forward ,as does her secretary ,to the completion of the building.她像她的秘书一样盼望工程竣工。

c)When in Rome do as Romans do.入乡随俗。

2....as he is
a)Talented as he is,he is not yet ready to turn professional.别看他有天份,他还没把心用到专业上去。

注:这是一种表示让步的分句,主要用于正式文体。Talented as he is =Though he is talented,as引出的主谓语倒装是强制性的,因为若将as置于句首,就不是让步状语从句了。由though

引出的让步状语从句,也可以使用这种语序,但不是强制性的。例如:

b)Coward though he is ,do not bully him.尽管他是个胆小鬼,但不要欺负他。

3.as far as /so far as

a)So far as I know,he will be away for three months.据我所知,他将离开这里三个月。
注:当as far as和so far as作"在……范围内……、一直到、到……那么远"解时,它们是可以互换的。当表示形容词、副词同级比较时,要求在肯定句中使用as far as。例如:

b)We didn't go so/as far as the bridge.我们没有走到桥那么远。

4.as/so far as to do(doing)something意思是:"竟到了……程度"。

a)At last,she went so far as to bring him to the apartment.最后,她竟把他带到了公寓。
注:as/so far as之后既可跟不定式也可跟动名词。例如:

b)I have considered having a car,but I haven't got so far as buying it yet.我是考虑要买一辆汽车,但是还没有到决定买的程度。

5.as follows意思是"如下的"。

a)His arguments are as follows.他的论点如下。

注:as follows是固定成语,不管引出的事物是单数还是复数,都只能用as follows(=as it follows),而不能用as follow。例如:

b)He explained it as follows .(=His explanation was as follows .)他的说明如下。

6.as for/as to意思是"至于、关于"。

a)Much pasture land is under water; and as for the grain,most of which has been ruined.大部分牧场都进了水,至于谷物,大部分都被冲毁了。

注:as for在语体上不如as to正式;前者着重话题的转换,因此,它不能用于文章的开头。例如:

b)As to the question you raised in your last letter ,I think....关于你上封信提出的问题,我认为……。

7.as good as意思是"差不多,几乎"。此外,该结构还保留其原意"和……一样好"。

a)Don't worry,the matter 's as good as settled.别担心,问题差不多已经解决了。

b)When the car was repaired,it looked as good as new.当这辆车修好的时候,它看起来差不多像新的一样。

8.as and when"到时候",指将来的某一未定的事或时候。

We'll decide on our team as and when we qualify for the competition.我们等到有资格参加比赛时,再来决定本队的参赛人员。

9.as if you were/are

a)He walks as if he were drunk.他走路的样子好像是喝醉了似的。(说话人认为他并没有喝
醉)

b)He walks as if he is drunk.他走路好像喝醉了。
注:一般来讲,如果as if表达的内容与事实相反或者是一种假使,通常使用虚拟语气。如例句a)。如果as if所表达的内容被看作是事实,就要使用陈述语气。如例句b)。

10.as it were /was(is)

a)As it was,they had no unity,no sense of cooperation .事实上,他们不团结,没有合作意识。

注:as it is /was是个成语,意思是:"事实上、实际上"。而as it were在意义和用法上与

as it is /was完全不同,意思是:"可以说是、似乎是、仿佛",它所表达的内容不太肯定。例如:

b)He is ,as it were,a walking dictionary.他简直可以说是一部活字典。

c)He is my best friend,my brother as it were.他是我最好的朋友,可以说是我的兄弟。

11.as long ago as/as long as

a)As long ago as the eleventh century the Chinese people not only invented the com pass but also used it in navigation.早在十一世纪中国人就不仅发明了指南针,而且还把它用到航海上。

b)I'm happy as long as you are happy.只要你幸福,我就感到幸福。

c)As long as you act so m ean,you can't expect anybody to do anything for you.由于
你行为卑劣,你不要指望有人会帮助你。

注:as long ago as可译为"早在……"。见例句a)。as long as/so long as引导一个条件状语从句,通常译为"只要"。见例句b)。此外,它还可以引导原因状语从句。见例句c)。

12.as long as /so long as

a)You can go out ,as long as you promise to be back before 10o'clock.只要你答应10点钟以前回来,你就可以出去。

注:当as long as和so long as作"只要"解时,可以看作是同义的,但是,当用于同级比较时,只能用as long as,而不能用so long as。见例句b)。

b)You can stay here as long as you want.你希望在这里呆多久就呆多久。
