2021年高考英语二轮复习 定语从句考点讲解（含解析）.docx

1、定语从句知识点一、定语从句与并列句的区别请观察下面三个句子：1Wang Hong failed in the College Entrance Examination, _ disappointed his mother.2Wang Hong failed in the College Entrance Examination and _ disappointed his mother.3Wang Hong failed in the College Entrance Examination; _ disappointed his mother.第一句话：句中有逗号，根据句意可知，空白处的内容

2、应该指的是前面整个句子的内容，是对前文信息的补充说明，因此，此句是非限制性定语从句，用关系代词which；第二句话：句中有并列连词and，因此整个句子是一个并列句，所以可以用代词it指代前面句子的内容。第三句话：句中有分号，这表明整个句子是一个并列句，因此可以用代词it指代前面句子的内容。【解题技巧】判断是定语从句还是并列句，要注意句中的标点符号和句中的连接词。如果句与句之间有连词或者分号，则是并列句；如果是逗号，且逗号后的内容是对前面某一名词的补充说明，则是非限制性定语从句，应该使用关系词。知识点二、“介词关系代词”引导的定语从句中介词的选择“介词关系代词”引导的定语从句中介词的选择是一个常

3、考点，也是一个难点。请看下面三个句子，填上合适的介词，并从中发现一些规律。1He was educated at a local grammar school, _ which he went on to Cambridge.2This is the farm _ which he worked two years ago.3In the dark street there was not a single person _ whom she could turn for help.第一句话：根据句意可知，他在一所当地的语法学校学习之后去了Cambridge，故介词用after。此句中介词的使

4、用与句子的意义有关。第二句话：把从句补充完整为he worked two years ago on the farm (“在农场”为“on the farm”)，句中介词的选用取决于先行词的意义，即介词跟先行词的搭配。第三句话：在黑暗的街道上，没有一个她可以求助的人。“向某人求助”这个短语是“turn to sb. for help”，因此此处用介词to。此句中介词的选用取决于从句中的动词固定搭配。因此，考生在确定其中的介词时，可从以下三方面入手：1句子的意思；2.先行词的意义；3.从句中的动词固定搭配。【特别提醒】注意way(方式)后接定语从句时的引导词。先行词是way，当引导词在从句中作状

5、语时，关系词用in which, that或者省略；当引导词在从句中作主语或宾语时，用that/which引导(作宾语时，引导词也可以省略)。比较：The way(that/which) he explained to us was quite simple.(把从句补充完整：he explained the way to us，可以看出引导词在从句中作explained的宾语)The way(that/in which) he explained the sentence was simple.(把从句补充完整：he explained the sentence in the way，可以看

6、出引导词在从句中作状语)知识点三、引导词as, which的区别1引导非限制性定语从句，指代整个主句内容时的区别：(1)表达“正如”之意时，用as，如果仅指代整个主句内容而没有“正如”之意，则用which。He went abroad, which was unexpected.他出国了，这让大家感到很意外。She is a good doctor, as her mother used to be.她是一个很出色的医生，和她母亲当年一样。(2)当从句位于主句前面时，只用as。As is known to everybody, the moon travels round the earth

7、once every month.2限制性定语从句中有such, the same时，其后常用as引导定语从句(the same后也可用that，但意义不一样)。He is such a good teacher as we all love and respect.他是一个我们都爱戴和尊敬的好老师。This is the same pen as I lost.这支钢笔和我丢的那支一样。3as引导非限制性定语从句时，只能指代整个主句内容，而which既可以指代整个主句内容，又可以指代先行词。The river, which flows through London, is called the

8、 Thames.这条流经伦敦的河叫泰晤士河。(不用as)4as常与从句中的know, see, hear, expect等动词连用，也常用于as often happens, as is often the case(常有的事)等句子中。He was absent from school, as is often the case.他缺课了，这是常事。知识点四、分隔定语从句一般情况下，定语从句紧跟先行词，可是有的时候，先行词与定语从句之间插入了另外一些内容，这样就把先行词与定语从句分隔开了，这类定语从句叫分隔定语从句。这类句子应特别注意：不要误把插入部分当先行词。I was the only

9、person in my office who was invited.(先行词是person而不是office)知识点五、关系代词和关系副词的区别当先行词为表示时间、地点的词时，引导词用关系代词还是关系副词是定语从句学习中的一个难点。要确定引导词在从句中所作的成分(如果引导词在从句中作状语，则用why, when或where，否则用that或which)，考生可以采用“补全法”，即依据句意把从句补充完整(补上去的部分在从句中所作的成分就是引导词在从句中所作的成分)，这样就可以很容易地判断出引导词在从句中所作的成分。1Do you still remember the chicken farm

10、 _ we visited three months ago?分析：把从句补充完整为“we visited the chicken farm three months ago”，考生据此可以判断出引导词在从句中作宾语，因此填关系代词that/which。2In an hour, we can travel to places _ would have taken our ancestors days to reach.分析：把从句补充完整为“the places would have taken our ancestors days to reach”，考生据此可以判断出引导词在从句中作主语，

11、因此填关系代词that/which。3Some preschool children go to a day care center, _ they learn simple games and songs.分析：把从句补充完整为“in (at) the day care center they learn simple games and songs”，据此可以判断出引导词在从句中作地点状语，因此用where/in(at) which。【解题技巧】遇到时间和地点，判断成分是关键；主语、宾语用关代，状语才能用关副。(关代：关系代词；关副：关系副词)在考查定语从句时，有时命题人故意在空格处设置一

12、些插入语等干扰信息迷惑考生。解题时，考生可以将其忽略，从而排除干扰。Is that the small town you often refer to?Right, just the one _ you know I used to work for years.分析：空白处应填where。此题很容易受you know的影响而误填关系代词。其实you know是插入语，解题时可以将其忽略，简化句子结构：just the one _ I used to work for years，这样考生就很容易判断出引导词在从句中作地点状语，故用关系副词where。【特别探究】表示时间、地点的先行词的模糊化

13、。研究高考试题后，考生会发现近几年高考试题中表示时间、地点的先行词有些已经不是一个明显的表示时间、地点的词语，如：period, ten years ago, the street, the museum，而是已经模糊化的词语，如：activity, business, occasion, point, case等。解题时考生要弄清这些词汇在句中的意义，并结合其在从句中所作的成分选用恰当的引导词。【特别提醒】point, situation, case后的定语从句的引导词并非总是由where来引导，只有当引导词在从句中作状语时，才用关系副词where，否则用关系代词。知识点六、定语从句用法的其

14、他要点(一)关系代词在定语从句中作主语时，不可省略(二)定语从句中的谓语动词的形式与先行词的单复数保持一致当引导定语从句的关系代词在从句中作主语时，那么定语从句中的谓语动词在人称、数方面应该与先行词保持一致。1one of复数名词关系代词复数形式动词。如：The Great Wall is one of the worldfamous buildings that draw lots of visitors.长城是吸引大批游客的世界著名的建筑之一。2the only one of复数名词关系代词单数形式动词。如：The Great Wall is the only one of the bui

15、ldings on the earth that is seen from the moon.长城是地球上唯一一个能从月球上看到的建筑物。Titanic is the only one of these wonderful movies that has been produced in Hollywood.在这些精彩的电影中，泰坦尼克号是唯一一部由好莱坞制作的电影。3当关系代词as与which引导非限制性定语从句，修饰主句内容时，若as与which作主语，则从句的谓语动词用单数形式。如：Great changes have taken place in China, as is known

16、to all.众所周知，中国发生了巨大的变化。He has passed the College Entrance Examination, which makes his parents quite happy.他通过了高考，这让他父母很高兴。4其他情况。如：I, who am your teacher, will try my best to help you.我作为你的老师，会尽全力帮助你的。(三)注意way和time后接的定语从句的情况1当先行词是way(意为“方式、方法”)时，引导定语从句的关系词有下列三种形式。如：What surprised me was not what he

17、said but the way he said it.最让我吃惊的不是他的话，而是他说话的方式。注意下面两个句子中关系词的不同，试比较：The way he explained to us was quite simple.他向我们解释的那种方法很简单。The way he explained the sentence to us was not difficult to understand.他向我们解释句子的那种方法不难理解。2先行词是time时， 若time作“次数”讲时，应用关系代词that引导定语从句，that可省略；若time作“一段时间”讲时，应用关系副词when或介词at/d

18、uringwhich引导定语从句。如：This is the second time (that) the President has visited the country.这是总统第二次访问这个国家。This was at a time when/during which there were no radios, no telephones or no TV sets.曾经有一个时期，没有收音机，没有电话，也没有电视。高频考点一、考查关系代词引导的定语从句例1 (2018北京卷)She and her family bicycle to work, _ helps them keep f
