關(guān)于as的用法及解釋

　　as有作副詞、介詞、連詞、代詞等四大用法，涉及的知識點有很多，詞性范圍也很大。接下來小編在這里給大家?guī)韆s的用法及解釋，我們一起來看看吧!

　　as的用法

　　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 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.他們團結(jié)得像一個人一樣。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)時間狀語從句，作“當(dāng)...的時候”解，有“隨著...”之意，與while意義相近，強調(diào)兩個動作同時發(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.他小時候就開始學(xué)彈鋼琴。2.引導(dǎo)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(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)你銘家一樣，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(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。
