“as...as…”意为"和……一样",表示同级的比较。使用时,as…as…句型中的第一个as的词性为副词,后面可以接形容词或者其他副词。第二个as的词性为连词,后面需要接从句。
基本结构为:as+ adj./ adv.+as…例如:
1、This film is as interesting as that one(is interesting).这部电影和那部电影一样有趣。
在这个句子中,因为前后比较的内容一致,所以我们可以把从句中的“is interesting”省略。
2、This room is as wide as that room is long.这间房间的宽度和那间房间的长度一样。
在这个例句中,因为前后比较的内容不同,采用的形容词不同,所以不能省略从句中的形容词。
扩展资料
as作介词进行使用:
1、作为,以...的身份
例如:He works as a tour guide. 他作为导游工作。
2、当作
例如:She is a famous person as a actress. 作为一个女演员,她很出名
3、像;如同
例如:The old woman was dressed as a young lady. 这位老妇人打扮得像一位年轻人。
as作代词进行使用:
1、(与such,the same,as等连用,引导关系从句)与...相同的事物(或人)
例如:He has earned as much money as I have. 他赚的钱和我赚的一样多。
2、(引导从句,对前述内容作补充)本情况、该事实
例如:She has married again, as was expected. 她已再婚,这是意料中的事。

第一个as是副词,第二个as是连词as用法小结
一)as作副词,表示程度,意为“同样地”。在“as...as...”,“not as...as...”结构中的第一个as是副词,作“和/与...(不)一样”解。eg:
Jack is as tall as his father.杰克和他的父亲一样高。
He doesn't speak English as/so fluently as you.他的英语说得不如你流利。
二)as作介词。
1.作“如,像”解。eg:
They got united as one man.他们团结得像一个人一样。
2.作“充当,作为”解。eg:
As a writer,he was famous.作为作家,他是很有名的。
三)as作连词,常用来连接主句和状语从句。
1.引导时间状语从句,作“当...的时候”解,有“随着...”之意,与while意义相近,强调两个动作同时发生;或某事一发生,另一事立即发生。eg:
He shouted aloud as her ran along.他一边往前跑,一边高声地呼喊。
I was startled as he opened the door.他一开门,我吓了一跳。
as作连词,相当于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。
2.引导原因状语从句,作“因为,由于”解,与because的用法相近。eg;
I must stop writing now,as I have rather a lot of work to do.我必须停笔了,因为我还有许多工作要做。
3.引导方式状语从句或比较状语从句,作“正如,(如)像”解。例eg:
As in your country,we grow wheat in the north and rice in the south.正如(像)你们国家一样,我们在北方种小麦,在南方种大米。(方式状语从句)
When at Rome,do as Romans do.入乡随俗。(方式状语从句)
4.引导让步状语从句,作“虽然,尽管”解。这时从句常用倒装语序,即把从句中的表语、状语或动词原形放在as之前。eg;
Strange as it may seem,it is true.尽管这事看上去很奇怪,但却是真的。
Try as he might,Tom could not get out of the difficulties.不管怎样努力,汤姆还是摆脱不了困境。
四)as作关系代词。
1.引导*性定语从句,用在“such...as”,“the same...as”,“as...as”等结构中,常译作“像...一样的人(或物)”,“凡是...的人(或物)”。例eg:
He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。
My hometown is no longer the same as it was.我的家乡再也不像过去一样了。
2.引导非*性定语从句,用来指代它前面的整个句子(即先行句),意思是“这一点”。这个分句可以位于句首、句中或句末。eg:
As is well known,oceans cover more than 70% of the earth.我们知道,海洋占地球面积的百分之七十以上。
五)含as的固定词组的用法
1.as soon as作“一…就”解,引导时间状语从句。eg:
As soon as I get to Beijing,I'll write to you.我一到北京,就给你写信。
2.as/so long as作“只要”解,eg;
As/So long as you study hard,you'll make progress.只要你努力,你就会取得进步。
3.as if/though常用来引导方式状语从句,作“好像,仿佛”解。如果从句中讲的是非真实情况,则用虚拟语气。eg:
She loves the child as if/though he were her own.她爱这个孩子如同爱自己的孩子。
As if/though也可用来引导表语从句,常用在“It appears/looks/seems...+as if/though”句型结构中。eg;
It appears as if/though it is going to clear up.看起来天要晴了。
It seems as if/though he knew nothing about it.他好像对此事一无所知。
4.as to作“关于,至于”解。eg;
There is no doubt as to his honesty.他的诚实是无可置疑的。
5.as much/many as作“多达...”,“达到...之多”解。eg:
He can earn as much as 5000 dollars a month.他每月能挣5000美元。
6.so/as far as I know作“就我所知”解,在句中作插入语。eg:
As/So far as I know,he will come here next Monday.据我所知,他将于下星期一到这里来。
7.as a result,as a result of表示“由于...的结果”。eg:
She died as a direct result of the accident.她的死是那次事故的直接结果。
8,as well为“也,还”之意。eg:
Come early,and bring your brother as well.早点来,把你的弟弟也带来。
9.so as to,so...as to若跟动词原形,表示目的或结果。eg:
He studied hard so as to pass the exam.他努力学习以便通过考试。(表示目的)
