      as用法總結(jié)

        總結(jié)是在一段時(shí)間內(nèi)對(duì)學(xué)習(xí)和工作生活等表現(xiàn)加以總結(jié)和概括的一種書(shū)面材料,它能夠使頭腦更加清醒,目標(biāo)更加明確,快快來(lái)寫(xiě)一份總結(jié)吧。那么我們?cè)撛趺慈?xiě)總結(jié)呢?下面是小編為大家整理的as用法總結(jié),僅供參考,歡迎大家閱讀。

      as用法總結(jié)

        一)as作副詞,表示程度,意為“同樣地”。在“as...as...”,“not as...as...”結(jié)構(gòu)中的第一個(gè)as是副詞,作“和/與...(不)一樣”解。eg:

        Jack is as tall as his father.杰克和他的父親一樣高。

        He doesnt speak English as/so fluently as you.他的英語(yǔ)說(shuō)得不如你流利。

        二)as作介詞。

        1、作“如,像”解。eg:

        They got united as one man.他們團(tuán)結(jié)得像一個(gè)人一樣。

        2、作“充當(dāng),作為”解。eg:

        As a writer,he was famous.作為作家,他是很有名的。

        三)as作連詞,常用來(lái)連接主句和狀語(yǔ)從句。

        1、引導(dǎo)時(shí)間狀語(yǔ)從句,作“當(dāng)...的時(shí)候”解,有“隨著...”之意,與while意義相近,強(qiáng)調(diào)兩個(gè)動(dòng)作同時(shí)發(fā)生;或某事一發(fā)生,另一事立即發(fā)生。eg:

        He shouted aloud as her ran along.他一邊往前跑,一邊高聲地呼喊。

        I was startled as he opened the door.他一開(kāi)門(mén),我嚇了一跳。

        as作連詞,相當(dāng)于when。eg;

        As a little boy (When he was a little boy)he began to learn to play piano.他小時(shí)候就開(kāi)始學(xué)彈鋼琴。

        2、引導(dǎo)原因狀語(yǔ)從句,作“因?yàn),由于”解,與because的用法相近。eg;

        I must stop writing now,as I have rather a lot of work to do.我必須停筆了,因?yàn)槲疫有許多工作要做。

        3、引導(dǎo)方式狀語(yǔ)從句或比較狀語(yǔ)從句,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)你們國(guó)家一樣,我們?cè)诒狈椒N小麥,在南方種大米。(方式狀語(yǔ)從句)

        When at Rome,do as Romans do.入鄉(xiāng)隨俗。(方式狀語(yǔ)從句)

        4、引導(dǎo)讓步狀語(yǔ)從句,作“雖然,盡管”解。這時(shí)從句常用倒裝語(yǔ)序,即把從句中的表語(yǔ)、狀語(yǔ)或動(dòng)詞原形放在as之前。eg;

        Strange as it may seem,it is true.盡管這事看上去很奇怪,但卻是真的。

        Try as he might,Tom could not get out of the difficulties.不管怎樣努力,湯姆還是擺脫不了困境。

        四)as作關(guān)系代詞。

        1、引導(dǎo)限制性定語(yǔ)從句,用在“such...as”,“the same...as”,“as...as”等結(jié)構(gòu)中,常譯作“像...一樣的人(或物)”,“凡是...的人(或物)”。例eg:

        He wished to be such a man as Lei Feng was.他曾希望做一個(gè)像雷鋒那樣的人。

        My hometown is no longer the same as it was.我的家鄉(xiāng)再也不像過(guò)去一樣了。

        2、引導(dǎo)非限制性定語(yǔ)從句,用來(lái)指代它前面的整個(gè)句子(即先行句),意思是“這一點(diǎn)”。這個(gè)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.我們知道,海洋占地球面積的百分之七十以上。

        五)含as的固定詞組的用法

        1、as soon as作“一…就”解,引導(dǎo)時(shí)間狀語(yǔ)從句。eg:

        As soon as I get to Beijing,Ill write to you.我一到北京,就給你寫(xiě)信。

        2、as/so long as作“只要”解,eg;

        As/So long as you study hard,youll make progress.只要你努力,你就會(huì)取得進(jìn)步。

        3、as if/though常用來(lái)引導(dǎo)方式狀語(yǔ)從句,作“好像,仿佛”解。如果從句中講的是非真實(shí)情況,則用虛擬語(yǔ)氣。eg:

        She loves the child as if/though he were her own.她愛(ài)這個(gè)孩子如同愛(ài)自己的孩子。

        As if/though也可用來(lái)引導(dǎo)表語(yǔ)從句,常用在“It appears/looks/seems...+as if/though”句型結(jié)構(gòu)中。eg;

        It appears as if/though it is going to clear up.看起來(lái)天要晴了。

        It seems as if/though he knew nothing about it.他好像對(duì)此事一無(wú)所知。

        4、as to作“關(guān)于,至于”解。eg;

        There is no doubt as to his honesty.他的誠(chéng)實(shí)是無(wú)可置疑的。

        5、as much/many as作“多達(dá)...”,“達(dá)到...之多”解。eg:

        He can earn as much as 5000 dollars a month.他每月能掙5000美元。

        6、so/as far as I know作“就我所知”解,在句中作插入語(yǔ)。eg:

        As/So far as I know,he will come here next Monday.據(jù)我所知,他將于下星期一到這里來(lái)。

        7、as a result,as a result of表示“由于...的結(jié)果”。eg:

        She died as a direct result of the accident.她的死是那次事故的直接結(jié)果。

        8、as well為“也,還”之意。eg:

        Come early,and bring your brother as well.早點(diǎn)來(lái),把你的弟弟也帶來(lái)。

        9、so as to,so...as to若跟動(dòng)詞原形,表示目的或結(jié)果。eg:

        He studied hard so as to pass the exam.他努力學(xué)習(xí)以便通過(guò)考試。(表示目的)

        as……as

        AS +adj(原級(jí))+AS

        AS +adv(原級(jí))+AS

        as soon as 一……就

        as soon as possible 盡可能快地

        as early as possible 盡可能早的

        as carefully as you can 盡可能認(rèn)真地

        as careful as you can 盡可能認(rèn)真的

        so...as 一般用于否定句,as...as 一般用于肯定句,(肯定否定都能用)

        so...as不可用于肯定句.as...as與so...as均可表示"與……一樣",as...as...的用法:兩個(gè)as中間可以加形容詞或者副詞,由它要修飾的內(nèi)容決定.

        它們的用法有異同之處:

        肯定句用as...as,不用so...as;否定句兩者均可使用.例如:

        I didnt go as /so far as you.我走得不像你那么遠(yuǎn).

        They walked as far as the station.他們步行到了車(chē)站.

        誤:They walked so far as the station.
