2026新高二英语暑假衔接（人教版）第01讲 Unit1 语法 非限制性定语从句（学生版）

第01讲非限制性定语从句

1．了解非限制性定语从句的概念和用法。

2．可以根据本节课的内容来完成一些习题。

定语从句（限制性和非限制性定语从句的区别）

1.定语从句有时跟先行词的关系并不十分密切，只是作一些补充说明，不起限制作用，这种

从句称为非限制性定语从句。它常常用逗号与主句分开；翻译时常译成并列的分句。例如：

ThisnotewasleftbyJohn,whowashereamomentago.

这条子是约翰留下的，他刚才来过这儿。

2.非限制性定语从句在修饰人时用who(主格),whom(宾格),whose(所有格),即：在定语从句中

关系代词指人做主语时，只能用who;作宾语时，只能用whom，不能有几种选择，也不能省

略，只有一种答案。在修饰物时用which而不能用that。总之，非限制性定语从句里没有that，

也没有why。

区别项目限制性定语从句非限制性定语从句

形式与主句之间不用逗号隔开，口语中不停与主句之间常用逗号隔开，口语中

顿。有停顿。

作用对先行词的意义进行修饰、限制，若去对先行词起补充说明作用，若省略，

掉，则句意不完整。句意仍然清楚、完整。

翻译与含义翻译在它所修饰的先行词之前，限制先翻译时与主句隔开，对先行词解释

行词。说明。

先行词名词或代词。名词、代词、短语或句子。

关系词各类关系词，有几种选择，有时可省。不用that和why，一般只有一种选

择，关系词不可省。

非限制性定语从句引导词的选择

关系代词的选择

A．非限制性定语从句的关系代词不能用that。指人时，如引导词作主语用who，作宾

语用whom；指物时要用which。即使引导词作宾语也不能省略。

①Mary，whoisfromAustralia，isanoldfriendofmine．

玛丽是我的老朋友，她来自澳大利亚。

②Bob'sfather，whoworkedontheproject，spentfouryearsinEgypt．

鲍勃的父亲从事这项工程，在埃及度过了四年。

B．as和which的选择

(1)as和which都可用来引导非限制性定语从句，来指代整个主句的内容。非限制性定

语从句位于句末且as或which在从句中作主语、宾语或表语时，两者常可互换。

Hefailedintheexam，which／aswasnatural．

他考试没及格，这很自然。(作主语)

但要注意以下区别：

如果非限制性定语从句位于主句之前或插在主句之中，只能用as。

Aswehaveseen，oceanscovermorethan70percentoftheearth．

我们已经看到，海洋占地球面积的70%多。

(2)as常用在一些固定结构中，如asweknow／asisknowntoall(众所周知)，asweallcan

see(正如我们大家都能看到的那样)，asisoftenthecase(情况常常是这样)，asmightbe

imagined(可以想象得到)，asmightbeexpected(正如所预料的那样)，ashasbeenpointedout(正

如所指出的那样)，ashasbeensaidbefore／above(正如前文所述)，as(is)oftenhappens(像往

常一样)。

Shehasbeenabsentagain，asoftenhappens．像往常一样，她又缺席了。

C．关系代词和关系副词的选择

在非限制性定语从句中，关系代词和关系副词的选择方法和限制性定语从句一样：引导

词在从句中作主语或宾语时，用关系代词；作状语时用关系副词。

Theoldmanhasadaughter，whoisadoctor．

这位老人有一个女儿，她是医生。(who作主语)

Iexperiencedahardsituationin2000，wherenobodycouldhelpme．

我在2000年经历了一段困难处境，没有人能帮我。(where作状语)

注意：(1)限制性定语从句的先行词只能是一个名词或代词，而非限制性定语从句的先

行词可以是一个词，也可以是一句话。试比较：

Thefilm，whichIsawlastnight，isveryinteresting．

这是我昨天晚上看过的电影，非常有意思。(先行词为film)

Thefilmisveryinteresting，whichmakesmeveryglad．

这部电影很有意思，这让我很高兴。(先行词为“Thefilmisveryinteresting”所表达的内

容。)

(2)关系代词替代情况不同。

在限制性定语从句中，先行词指人时，关系代词可用who、that或whom，但在非限制

性定语从句中先行词指人时，关系代词只能用who或whom。

Tomhasabrother，thatisaworker．(误)

Tomhasabrother，whoisaworker．(正)
