关于as的用法及解释
as有作副词、介词、连词、代词等四大用法，涉及的知识点有很多，词性范围也很大。接下来我在这里给大家带来as的用法及解释，我们一起来看看吧!
as的用法
as作副词，表示程度，意为“同样地”。在“as...as...”，“not as...as...”结构中的第一个as是副词，作“和/与...(不)一样”解。eg：Jack is as tall as his father.杰克和他的父亲一样高。He doesn't speak English as/so fluently as you.他的英语说得不如你流利。二)as作介词。1.作“如，像”解。eg：They got united as one man.他们团结得像一个人一样。2.作“充当，作为”解。eg：As a writer，he was famous.作为作家，他是很有名的。三)as作连词，常用来连接主句和状语从句。1.引导时间状语从句，作“当...的时候”解，有“随着...”之意，与while意义相近，强调两个动作同时发生;或某事一发生，另一事立即发生。eg：He shouted aloud as her ran along.他一边往前跑，一边高声地呼喊。I was startled as he opened the door.他一开门，我吓了一跳。as作连词，相当于when。eg;As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。2.引导原因状语从句，作“因为，由于”解，与because的用法相近。eg;I must stop writing now，as I have rather a lot of work to do.我必须停笔了，因为我还有许多工作要做。3.引导方式状语从句或比较状语从句，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)你铭家一样，我们在北方种小麦，在南方种大米。(方式状语从句)When at Rome，do as Romans do.入乡随俗。(方式状语从句)4.引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg;Strange as it may seem，it is true.尽管这事看上去很奇怪，但却是真的。Try as he might，Tom could not get out of the difficulties.不管怎样努力，汤姆还是摆脱不了困境。四)as作关系代词。1.引导限制性定语从句，用在“such...as”,“the same...as”，“as...as”等结构中，常译作“像...一样的人(或物)”，“凡是...的人(或物)”。例eg：He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。My hometown is no longer the same as it was.我的家乡再也不像过去一样了。2.引导非限制性定语从句，用来指代它前面的整个句子(即先行句)，意思是“这一点”。这个分句可以位于句首、句中或句末。eg：As is well known，oceans cover more than 70% of the earth.我们知道，海洋占地球面积的百分之七十以上。
