as用法總結
總結是在一段時間內對學習和工作生活等表現加以總結和概括的一種書面材料，它能夠使頭腦更加清醒，目標更加明確，快快來寫一份總結吧。那么我們該怎么去寫總結呢？下面是小編為大家整理的as用法總結，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...”結構中的第一個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.他們團結得像一個人一樣。
2、作“充當，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、引導時間狀語從句，作“當...的時候”解，有“隨著...”之意，與while意義相近，強調兩個動作同時發生;或某事一發生，另一事立即發生。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，相當于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小時候就開始學彈鋼琴。
2、引導原因狀語從句，作“因為，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，因為我還有許多工作要做。
3、引導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，我們在北方種小麥，在南方種大米。(方式狀語從句)
When at Rome，do as Romans do.入鄉隨俗。(方式狀語從句)
4、引導讓步狀語從句，作“雖然，盡管”解。這時從句常用倒裝語序，即把從句中的表語、狀語或動詞原形放在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作關系代詞。
1、引導限制性定語從句，用在“such...as”,“the same...as”，“as...as”等結構中，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.他曾希望做一個像雷鋒那樣的人。
My hometown is no longer the same as it was.我的家鄉再也不像過去一樣了。
2、引導非限制性定語從句，用來指代它前面的整個句子(即先行句)，意思是“這一點”。這個分句可以位于句首、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，引導時間狀語從句。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，你就會取得進步。
3、as if/though常用來引導方式狀語從句，作“好像，仿佛”解。如果從句中講的是非真實情況，則用虛擬語氣。eg：
She loves the child as if/though he were her own.她愛這個孩子如同愛自己的孩子。
As if/though也可用來引導表語從句，常用在“It appears/looks/seems...+as if/though”句型結構中。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.他好像對此事一無所知。
4、as to作“關于，至于”解。eg;
There is no doubt as to his honesty.他的誠實是無可置疑的。
5、as much/many as作“多達...”，“達到...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...的結果”。eg：
She died as a direct result of the accident.她的死是那次事故的直接結果。
8、as well為“也，還”之意。eg：
Come early，and bring your brother as well.早點來，把你的弟弟也帶來。
9、so as to，so...as to若跟動詞原形，表示目的或結果。eg：
He studied hard so as to pass the exam.他努力學習以便通過考試。(表示目的)
as……as
AS +adj(原級)+AS
AS +adv(原級)+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 盡可能認真地
as careful as you can 盡可能認真的
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as中間可以加形容詞或者副詞,由它要修飾的內容決定.
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.
They walked as far as the station.他們步行到了車站.
誤:They walked so far as the station.
