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)和概括的一種書面材料，它能夠使頭腦更加清醒，目標(biāo)更加明確，快快來寫一份總結(jié)吧。那么我們?cè)撛趺慈懣偨Y(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。
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.他的英語說得不如你流利。
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，常用來連接主句和狀語從句。
1、引導(dǎo)時(shí)間狀語從句，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.他一開門，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)候就開始學(xué)彈鋼琴。
2、引導(dǎo)原因狀語從句，作“因?yàn)椋捎凇苯�，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)方式狀語從句或比較狀語從句，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)你們國家一樣，我們?cè)诒狈椒N小麥，在南方種大米。(方式狀語從句)
When at Rome，do as Romans do.入鄉(xiāng)隨俗。(方式狀語從句)
4、引導(dǎo)讓步狀語從句，作“雖然，盡管”解。這時(shí)從句常用倒裝語序，即把從句中的表語、狀語或動(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)再也不像過去一樣了。
2、引導(dǎo)非限制性定語從句，用來指代它前面的整個(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)間狀語從句。eg：
As soon as I get to Beijing，Ill write to you.我一到北京，就給你寫信。
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常用來引導(dǎo)方式狀語從句，作“好像，仿佛”解。如果從句中講的是非真實(shí)情況，則用虛擬語氣。eg：
She loves the child as if/though he were her own.她愛這個(gè)孩子如同愛自己的孩子。
As if/though也可用來引導(dǎo)表語從句，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.看起來天要晴了。
It seems as if/though he knew nothing about it.他好像對(duì)此事一無所知。
4、as to作“關(guān)于，至于”解。eg;
There is no doubt as to his honesty.他的誠實(shí)是無可置疑的。
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。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。
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，把你的弟弟也帶來。
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.他們步行到了車站.
誤:They walked so far as the station.
