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
1.as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,而是指代整个主句或主句的一部分,意为“正如,如同”。这种从句可放在主句之前,也可以放在主句之后,有时还可以放在句子的中间。
As is reported in the newspapers,talks between the two countries are making progress.
正如报纸所报道的,两国间的谈判有所进展。
Grammar is not a set of dead rules,as has been said above.
如上所说,语法不是一套死条文。
Spiders are not insects,as many people think,nor even nearly related to them.
蜘蛛不是昆虫,尽管许多人都这样认为,它甚至与昆虫没有关系。
2.as引导限制性定语从句,主要用于the same...as(与……相同),such...as(像……一样),as...as(与……一样)等词组。
She knew he felt just the same as she did.
她知道他的感受和她一样。
Such a man with a good temper as Mr. Li is easy to get along with.
像李先生这样好脾气的人是容易相处的。
He smokes as expensive a cigarette as he can afford.
他抽一种他买得起的价格的香烟。
二、as作为从属连词引导时间状语从句
表示“随着……”“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。
I saw him as he was getting off the bus.
当他下公共汽车的时候,我看见了他。
The boy was singing a popular song as he was bicycling.
这男孩边骑车边唱歌。
As she grew older,she became less active.
当长大一点的时候,她就变得不那么活泼了。
三、as作为从属连词引导原因状语从句
as引导的原因状语从句常放在主句前,表示“因为,由于”。
As you were out,I left a message.
你不在,所以我留了一张字条儿。
As she is a model teacher,she sets a good example to others.
因为她是一名模范教师,她给其他人树立了一个好的典范。
As he wasnt ready in time,we went to the cinema without him.
由于他没有及时准备好,我们就先去看电影了,没有等他。
四、as作為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。
