高中英语as用法全归

as的用法灵活,词义繁多,特别是在复合句中更能体现其用法的多样性和灵活性,但如果同学们能正确掌握as的词性和词义,是不难掌握其用法的。

一、as用作关系代词引导定语从句
引导非限制性定语从句,一般不指代某个具体的名词或代词,而是代表整个主句或主句的一部分。

这种从句可放在主句之前,也可以放在主句之后,有时还可以放在主句的中间。

如:
Asisreportedinthenew spapers,talksbetweenthetw ocountriesaremakingprogr ess.正如在报纸上所报道
的,两国间的谈判有所进
展。

Grammarisnotasetofd eadrules,ashasbeensaidabo ve.如上所说,语法不是一
套死条文。

Spidersarenotinsects, asmanypeoplethink,noreve nnearlyrelatedtothem.蜘蛛
不是昆虫,尽管许多人都
这样认为,它甚至与昆虫
几乎没有联系。

引导限制性定语从句,主要用于thesame…as(与……相同),such…as(像……一样),as…as(与……一样)。

如:
Sheknewhefeltjustthe sameasshedid.她知道他的感受和她一样。

.像李先生这样好脾气的人是容易相处的。

Hesmokesasexpensive acigaretteashecanafford.他抽一种他买得起的最贵的烟。

二、as作为从属连词引导时间状语从句
表示“随着……”或者“当……的时候”或“一边……一边”,强调主句的动作和从句的动作同时发生。

如:

Theboywassingingapo pularsongashewasbicyclin g.这男孩边骑车边唱歌。

Asshegrewolder,shebe camelessactive.当她长大一点的时候,就变得不那么活泼了。

as引导的原因状语从句常放在主句前,表示“因为,由于”。

师,她给其他人树立了一个好的典范。

Ashewasn’treadyinti me,wewenttothecinemawit houthim.
由于他没有及时准备好,我们就去看电影了,没有等他。

三、as作为从属连词,引导让步状语从句
as引导让步状语从句比较特别,它要求将表语
和状语或谓语的一部分倒装。

如:
Oldasheis,heisstillfull ofenergy.尽管年纪大了,但他依然精力充沛。

Tryasshemay,sheneve rsucceeds.尽管她很努力,但总是不成功。

,Idon’tlikehimasaman.尽管我喜欢王先生的诗歌,但我不喜欢他的为人。

注:当倒装后置于句首的名词为单数可数名词时,习惯上不带冠词。

如:
Boyashewas,hewasma deking.尽管他还是个孩子,却被立为国王了。

四.as用作从属连词,引导方式状语从句

限制状语从句。

一些关于相关练习,这样便可掌握其用法了。
