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。

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。

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。
