He is honest, as we can see.他很诚实,这一点我们看得出来。

2、as 引导的非限制性定语从句可以放在主句之前、主句之后,甚至还可以分割主句。

另外,as 常常有“正如、正像”的含义。

He is from the south, as we can know from his accent.他是南方人,从他的口音我们就可以知道。

This is the same dictionary as I lost last week.这部词典跟我上星期丢失的一样。

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。
