定语从句中as的用法简述

定语从句的引导词很多,大致可以分为关系代词和关系副词,其中,关系代词里较为常见的有that, which, as等,这几个关系代词用法比较多,也有许多需要特别注意的地方,小编建议大家逐个记忆,不要记混,下面我们来看一下as的用法。

as引导非限制性定语从句时有许多常用句式:

As is known to all, the earth moves around the sun. 众所周知,地球围着太阳转。(as is known to all 众所周知)

As is reported in the newspaper, the economic of our country has increased in last year. 正如报纸所报道的,我们国家的经济在去年有所增长。(as is reported in the newspaper 如报纸所报道的)

As is said above,this plan can be carried out totally. 综上所述,这项计划完全可以实施。( as is said above 综上所述)

As was expected, he was elected as the chairman. 正如预料的那样,他当选为主席。(as was expected正如预料的那样)

as引导限制性定语从句时,需要注意两个结构:

such....as表示“像……这(那)样”

He is such an unselfish man as we respect.他像我们所尊敬的那种无私的人。

the same...that...表示同一人或物,而the same...as...表示同种类的东西,两者都引导定语从句,试比较下列两个句子:

This is the same pencil that I lost. 这支铅笔就是我丢的那一支。This is the same pencil as I lost. 这支铅笔跟我丢的那支笔一模一样。

As不只在引导定语从句时有多种结构,其实它本身就是一个非常灵活常用的单词,在多个英语学习版块中都能见到它,虽然as只是一个小词,但我们真的应该好好了解一下它的用法。
