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:

as用法總結(jié)

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

  He doesn't 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(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。
