定语从句as例句
定语从句as例句定语从句是一种常见的语法结构，通过使用关系代词来引导一个从句，对先行词进行修饰和限制。
在定语从句中，as是一个常用的关系代词，可以引导限制性定语从句和非限制性定语从句。
1. 限制性定语从句限制性定语从句对先行词进行修饰和限制，如果去掉定语从句，主句的意思会不完整或不明确。
例如：I have a car, which is red.（限制性定语从句，修饰先行词car）As a student, he has many duties to fulfill.（限制性定语从句，修饰先行词student）2. 非限制性定语从句非限制性定语从句对先行词进行补充说明，即使去掉定语从句，主句的意思仍然完整明确。
例如：John, who is a diligent student, passed the exam.（非限制性定语从句，补充说明先行词John）The book, which was written by an expert, is popular.（非限制性定语从句，补充说明先行词book）3. 介词 + 关系代词在某些情况下，我们可能会在介词后面使用as作为关系代词。
例如：The book, for which he paid $10, is worth reading.（介词 + 关系代词，as代替先行词book）He is a person, to whom we can turn for help.（介词 + 关系代词，as 代替先行词person）4. 省略引导词的情况在定语从句中，有时可以省略引导词as，尤其是当定语从句中有固定词组或短语时。
例如：He is a kind-hearted man (as) everyone knows.（省略引导词as）The book (as) you recommended is very interesting.（省略引导词as）5. 引导词as的特殊用法除了以上提到的用法外，as还可以用于一些特殊用法中，例如固定词组“as it is”表示“照现状”、“按照原样”，以及固定词组“as it were”表示“仿佛”、“似乎”。

as引导六大从句
as是考研英语中十分罕见的单词，用法灵活多样，是英语中最经常使用的词汇之一。
as主要有两种词性，分别为介词和连词。
as作为介词时，用法和语义较单一，其含义为“作为”。
但是as作为连词词性时，其用法和功能较多，可以引导各类从句，而对其所引导的从句类型的识别也就成为了as理解的难点。
在此对as引导各类从句进行汇总，并对各类从句的特点给出具体总结。
一、as引导定语从句as引导定语从句时，既可以引导限定性定语从句，又可以引导非限定性定语从句。
区分as引导定语从句和其它从句的关键特征是：as引导定语从句时在从句中做成分，通常做主语或宾语。
1、as引导限定性定语从句。
如从句所修饰的名词前有such、the same、as出现，后面的定语从句将由as引导，形成such...as，the same...as，as…as这样的固定结构，译为“和……一样”。
例1：I never heard such stories as he told.我从未听过他所讲的那样的故事。
例2：He’ll repeat such questions as are discussed in the book.他将重复书中讨论过的问题。
例3：They made the same mistake as others would have made on such an occasion.他们犯了和其他人在这种场合下会犯的同样错误。
2、as引导非限定性定语从句。
as引导非限定性定语从句，往往指代一整句话，通常暗示“正如”的意思。
as引导的非限制性定语从句位置相对比较灵活，可以位于先行词之前、之后或中间。
例：As is known to everybody, the moon travels round the earth.众所周知，月亮绕着地球转。
二、as引导时间状语从句as引导时间状语从句多用于口语，强调“同一时间”或“一先一后”，有时还有“随着”的含义。
制性定语从句VS非限制性定语从句 as引导的定语从句常见
在限制性定语从句中，当先行词指人时， 关系词可用who(m)或that，二者常可互换。 但在下列情况中，用who(m)，而不用that： (1) 当先行词是one, ones, any, few, anyone, anybody, someone, somebody, everyone, everybody 等词时 He was among the few who managed to live through the enemy prison camp. 注：在非正式文体中可以说： You’re the one that knows where to go.
引导非限制性定语从句的关系词有： who, whom, whose, which, as, when 和 where 不可以用that和why
另外，非限制Biblioteka 定语从句从意义上讲，相当于一个并列 句，在口语中使用并不普遍，在日常生活中，人们通常 用并列句或简单句来表达。
I told the story to John, who later did it to his brother. = I told the story to John, and he later told it to his brother.
(1)限制性定语从句说明先行词的情况，对先行 词起限定作用，与先行词关系十分密切，不可 用逗号隔开，也不可省略，否则全句意义就不 完整。 This is the telegram which he refers to. Is there anything (that) I can do for you?
2 Let’s discuss only such questions as concern every one of us. 3 Would you please buy me the same novel as you bought for brother yesterday, Mum? 4 As we all know, John is an honest man. 5 This is so difficult a problem as nobody in my class can work out.

5．关系词的省略不同 在限制性定语从句中，当关系代词在定
语从句中作宾语或表语时，在口语中可 以省略 而非限制性定语从句中的关系代词或关 系副词不可省略。 I still remember the days we spent together in college.
She is not the one(that) she used to be.
含义不同
I have a sister who is a doctor. (姐姐不止一个)
I have a sister, who is a doctor. (只有一个姐姐)
