考点巩固卷05 关系副词引导的定语从句高考真题1.（2023全国甲卷）“There was once a town in the heart of America, 64 all life seemed to enjoy peaceful existence with is surroundings,” her fable begins, borrowing some familiar words from many age-old fables.答案：where。

解析：考查定语从句。

句意：“从前，在美国的中心地带有一个小镇，那里全部的生命好像都和四周的环境一起享受着和平的生活，”她的寓言是这样开头的，借用了很多古老寓言中的一些生疏的词。

句中先行词为town，在非限定性定语从句作地点状语，所以用关系副词where引导。

故填where。

2.（2020全国I卷）Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot ___________ it could send signals to the spacecraft and to Earth.2. where【解析】句意：中国首先必需把一颗人造卫星送入月球轨道上的一个点，人造卫星可以在这个点向航天器和地球放射信号。

分析句子可知，空处引导一个定语从句，先行词是a spot，关系词替代先行词在从句中作地点状语，应用where引导。

故填where。

3.（2016全国I卷）But my connection with pandas goes back to my days on a TV show in the mid-1980s, ____________I was the first Western TV reporter was permitted to film a special unit caring for pandas rescued from starvation in the wild.答案：when解析：考查定语从句。

在复合句中充当定语的从句叫定语从句。

定语从句的作用相当于形容词，用来修饰主句中的某一名词或代词或整个主句，所以，也称作形容词性从句。

被定语从句修饰的词叫先行词，定语从句一般紧跟在它所修饰的先行词之后。

在先行词和定语从句之间起连接作用的词叫关系词。

关系词有关系代词和关系副词两种。

提示：关系词在定语从句中有三大作用1. 连接作用——连接先行词和定语从句。

I I . 我把我所有的钱都给了她。

（连接先特词和定语从句I ）2. 替代作用——在定语从句中替代从句所修饰的先行词。

a . 住在隔壁的那个人是个名师。

（替代）3. 成分作用——在定语从句中作主语、宾语、定语或状语。

I . 我喜欢传统的中国画。

（在定语从句中作主语）一、关系代词引导的定语从句引导定语从句的关系代词主要有, , , , 等。

它们分别代替前面的先行词，并在定语从句中作主语、宾语或定语。

A．指人，在定语从句中作主语。

借钱给你的那人叫什么名字？（定语从句修饰先行词）. 谁笑到最后谁笑得最好。

（定语从句修饰先行词）会议主席坐在我右边，他先发言。

（定语从句修饰先行词）B．指人，在定语从句中做宾语。

在口语或非正式文体中，可省略或可用来代替，但在介词后面以与在非限制性定语从句中只能用。

有些人我们是喜欢的，有些人则是我们讨厌的。

（定语从句分别修饰先行词, ）I .和我一起工作的人都很友好。

（定语从句修饰先行词）. , I , .. , I , .昨晚我在里和卡特先生交谈过，他对我们的计划很感兴趣。

（非限制性定语从句中不能用代替）, I , .两个人来到我的办公室，我以前从未见过他们。

（在介词后面不用）C．人、物皆可，做定语，后面要紧跟被修饰的名词，先行词和后面的名词之间往往是从属关系。

有些人，他们的脸你永远难以忘怀。

（定语从句修饰先行词）I .我看见一些树的树叶由于空气污染而发黑。

（定语从句修饰行词）D．1．指物，在定语从句中做主语或宾语。

做宾语时常可省略。

巩固练习将下面的两个简单句合并成一个含有定语从句的复合句。

1. She is the girl I went there with the girl.→_______________________________________________________________2. I want to find the pen.

高考英语定语从句知识精讲一、关系代词引导的定语从句1、that 指人或物在从句中作主语，宾语或表语；which 指物在从句中作主语，宾语或表语（作宾语时可以省略）；who 指人在从句中作主语，宾语或表语（作宾语时可以省略）；whom 指人在从句中作宾语（作宾语时可以省略）；whose 指人或物在从句中作定语；as 指人或物在从句中作主语，宾语或表语；注意：指物时，whose+名词 = the+名词+of which 或 of which + the +名词2、as 的用法（1）常用于下列结构：such…as; so…as; the same…as;注意：the same…as 表示同一类，不同一个the same…that 表示同一个（2）as与which的区别a、位置不同as可放在主句后，主句前或主句中间；which只能放在主句后。

b、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。

which相当于并列句，可以用and this来代替，意为“这一点，这件事’”。

注意：as常用于下列结构：as we know/ as is known to all, as we all can see, as has been said before/above, as might be excepted, as is often the case, 一般不能用which 代替as。

c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。

二、只用that不用which的情况1、先行词为 all, much, everything, nothing, something, anything, nothing, none, the one等不定代词时2、先行词被only, any, few, little, no , all, just , very ,right等修饰时.3、当先行词是最高级或被形容词最高级修饰时。
