as用在定语从句中的用法

as用在定语从句中的用法

as用在定语从句中的用法一、AS用在定语从句中的基本用法与关系代词用法区别在英语中,定语从句通常由关系词引导。

这些关系词包括that、who、whom、whose和which等。

然而,在某些情况下,我们可以使用介词as来引导定语从句,表示“...的”。

本文将介绍AS在定语从句中的基本用法,并与其他关系代词进行比较。

1. AS作为关系代词引导定语从句AS在定语从句中可以指人或物。

当AS引导的定语从句修饰人时,作为主格或宾格,它可以替代一个具体名词或指示形容词短语。

例如:- She works as a teacher, which I admire.(她是一名教师,我很钦佩)- My neighbor's son, as I previously mentioned, is a doctor.(我之前提到过的邻居儿子是医生)2. AS和WHEN对时间进行修饰除了指人之外,AS还可用于修饰时间的定语从句。

它可以替代表示具体时刻或事件的名词。

例如:- September 4th, as you might remember, was our wedding anniversary.(9月4日是我们的结婚纪念日,你可能记得)- He always wakes up early, as his alarm clock rings.(当闹钟响起时,他总是醒得很早)3. AS和THAT的区别AS所引导的定语从句与由THAT引导的定语从句在用法上有所不同。

AS常用于对一个已知事实或情况进行补充说明,而THAT更常用于简明地陈述或描述事实。

例如:- He referred to the book as a valuable resource.(他把这本书称为宝贵的资源)- The fact that he won the award surprised everyone.(他获奖的事实让所有人都感到惊讶)二、AS用在定语从句中的扩展应用除了上述基本用法之外,AS还有一些特殊的扩展应用,我们将在以下几个方面进行讨论。

as引导定语从句的用法

as引导定语从句的用法

as引导定语从句的用法as引导定语从句的用法定语从句(也称关系从句、形容词性从句),是指一类由关系词引导的从句,因为这类从句的句法功能多是做定语,所以曾被称为定语从句,这类从句除了可以做定语之外,还可以充当状语等其他成分,所以现代语言学多使用“关系从句”这一术语。

以下是店铺为大家整理的as引导定语从句的用法,仅供参考,希望能够帮助大家!as作关系代词时,引导定语从句在从句中充当主语、宾语、介词宾语或表语,既可以指人,也可以指物。

(1)as引导定语从句时,有如下结构:“the same …as”,“such …as”,“as…as”“so many (much, few, little)…as”,译作“像……一样的人(或物)”。

例如:This is such an easy novel as you can read.这本小说很容易,你能读得懂。

They have never read so many books as I read last year.他们从来都没有读过像我去年读过的那些书。

(2)as单独引导定语从句时,修饰整个主句或主句中的一部分,可以放在句首、句中或句末。

当as在从句中作主语时,从句的'谓语通常是被动语态或系表结构;as在从句中作宾语时,从句的谓语常用“情态动词+动词原形”构成。

常见的结构如下:as is known to all 众所周知as has been said above 如上所述as was expected 正如预料的那样as has been pointed out 正如他指出的那样as we all can see (know, hear)正如大家看到的(知道的、听到的)那样。

as 引导定于从句:
1、as用作关系代词和关系副词引导限定性定语从句,并在从句中做主语、表语和状语,构成the same ...as, such...as等结构。

Eg: I have got into the same trouble as you.
2、as引出非限定性定语从句时,代替整个主句,对其进行说明。

但通常用于:(as we all know, as it is known, as is known to all, as it is, as is said above, as always mentioned above, as is usual, as is often the case, as is reported in the newspaper) .
as在非限定性定语从句中作主语、表语或宾语,且引出的从句位置比较灵活,可位于句首或句末,也可置于主句中间。

通常均由逗号将其与主句隔开。

as有“正如……,就像……”之意。

Eg:
As is known to the United States, Mark Twain is a great American writer. 美国人都知道,马克·吐温是一位伟大的美国作家(as在从句中作主语)He forgot to bring his pen with him, as was often the case.
他忘了带笔,这是常事。

(as在从句中作主语)

(as在从句中作宾语)
注意:which引导的非限制性定语从句只能放在主句之后。

Eg: He hse been to Paris more than several times, which I don’t believe.
as 引导非限制性定语从句时与which的区别:
①当主句和从句语义一致时,用as;反之,用which来引导非限制性定语从句。

e.g. He made a long speech, as we expected.
He made a long speech, which was unexpected.
②当非限制定语从句为否定时,常用which引导。

e.g. Tom drinks a lot every day, which his wife doesn’t like at all.。
