高三英语语法限制性定从和非限制性定从的区别.docx

1、高三英语语法限制性定从和非限制性定从的区别定语从句拓展讲解考向一 介词+关系代词引导的定语从句介词关系代词的用法当关系代词在定语从句中作介词宾语时，我们通常用介词关系代词引导定语从句。如果指人，用介词whom；如果指物，用介词which。介词关系代词结构中介词的选用1.一般来说，确定关系代词前的介词，可以从以下三方面入手：先行词的意义；从句中的动词或形容词与先行词的固定搭配；句子的意思。Ill never forget the time during which I spent my childhood in the country.我永远不会忘记孩童时代我在乡村度过的时光。2.表示整体和部分

2、关系，介词常用of。在some，any，few，none，all，both，neither，most，each等代词或数词的前、后可以用of which/whom。John invited about 40 people to his wedding，most of whom are family members.约翰邀请了大约40人参加他的婚礼，他们当中绝大部分是家庭成员。3.有时介词where可以引导定语从句，此时要和介词which引导的定语从句从意思上加以区别。His head soon appeared out of the window，from where he saw nothi

3、ng but trees.他的头很快从窗口探了出来，从那里除了树木他什么也看不到。(from where相当于from out of the window，而不是from the window)在定语从句中，含介词的短语动词不可拆开使用(短语拆开后含义发生变化)，如look after, look for等。of which / whom有时可以用whose名词结构来改写。当先行词为way并且定语从句中缺少状语时，通常用in which或that引导定语从句(in which或that可省略)；如果定语从句中不缺少状语，则用关系代词引导(that 或which 可省略)。1.(2017江苏卷单

4、项填空) In 1963 the UN set up the World Food Programme, one of _ purposes is to relieve worldwide starvation.A. whichB. itsC. whoseD. whom【查看答案】【参考答案】C【答案解析】考查定语从句。分析句子结构可知，one of _ purposes is to relieve worldwide starvation是非限制性定语从句，先行词是the World Food Programme，关系词在非限制性定语从句中作定语，修饰名词purposes，所以用关系代词wh

5、ose引导，故选C项。句意：1963年，联合国成立了世界粮食计划署，其目的之一就是缓解世界范围内的饥荒。2.（2016 江苏卷单项填空）Many young people, most _were well-educated, headed for remote regions to chase their dreams.A. of which B. of them C. of whom D. of those【查看答案】【参考答案】C【答案解析】考查定语从句。本题定语从句的先行词是Many young people，关系代词whom指代先行词，在定语从句中作介词of的宾语。句意：很多年轻人都前

6、往偏远地区追求它们的梦想，其中大部分人都受过良好教育。故C项正确。考向二 定语从句与其他句型的区别一、限制性定语从句与同位语从句的区别关系副词引导限制性定语从句中的关系词有跟他们含义相应的先行词，而引导同位语从句时则没有与他们含义相应的先行词。Sorry, Ive forgot the day when we met for the first time.抱歉，我记不起我们第一次见面的日子了。（定语从句，先行词the day 与when含义相应）Ive no idea when we met for the first time.我不知道我们第一次是什么时候见面的。（同位语从句，idea与wh

7、en没有任何联系）二、定语从句与时间状语从句的区别当定语从句的引导词与时间状语从句的连接词都是when时，定语从句修饰、限制、说明时间名词，只能放在先行词的后面；而时间状语从句说明动作发生的情况，并且可以放在主句的前面。Do you know the time when the class is over? 你知道下课的时间吗？（定语从句）It was already five oclock when the class was over.=When the class was over, it was already five oclock.当课结束时，已经是五点钟了。（时间状语从句）三、定

8、语从句与地点状语从句的区别当定语从句的引导词与地点状语从句的连接词都是where时，定语从句修饰、限制、说明地点名词；而状语从句则说明动作发生的地点，where没有对应的地点名词或代词。This is the place where we used to live a few years ago.这就是几年前我们常居住的地方。（定语从句）Lets go where we can find a better job.我们到我们能找到更好工作的地方去吧。（地点状语从句）四、定语从句与强调句型的区别定语从句对名词或代词的修饰和限制，关系词可能是that, which, as, who, but, 另

9、一方面，句子中的It有所指；而强调句型是对某部分加强语气，强调语气的连接词只能是that, who，并且句子中的It 没有任何意义；一般比较明显，而有时就难以区别，还需要根据上下文的语境来判断。It is a book that he wants.它究竟是强调句型还是定语从句，就要从语境上来考察。如果它是用来回答What is this / that? 这样的问题，意思是：它是一本他想要的书。句子显然是定语从句。如果是用来回答What does he want? 这样的问题，那么意思是：他想要的是一本书。显然，句子是强调句型。五、定语从句与结果状语从句的区别定语从句中的关系词在从句中还要作某种

10、成分，因而从句成分不完整；而结果状语从句中的连接词不作任何句子成分，因此句子成分完整。It is such an interesting book as we all like.它是我们大家都喜欢的如此有趣的书。（定语从句）It is such an interesting book that we all like it.它是一本如此有趣的书，我么大家都喜欢它。（结果状语从句）比较：It is such an interesting book that we all like. 强调句型。意思是：我们大家都喜欢的是一本如此有趣的书。六、定语从句与独立主格结构的区别定语从句一般有关系词、主谓结

11、构完整；而独立主格结构没有关系词、也没有谓语动词。The book being very interesting, we all like it. 由于这本书有趣，我们大家都喜欢它。The book which / that is very interesting was published last year. 这本有趣的书是去年出版的。例题解析：1.He wrote a lot of novels, none of _ were popular.Its the same with his wife. She wrote some plays, but none of _ was a suc

12、cess.A. these；them B. which；which C. those；which D. which；them【查看答案】【参考答案】D【答案解析】本题很容易误选A、B。选对该题的关键是：要注意前面一句的 none of.没有并列连词（说明它才是非限制性定语从句，所以其后填which）；而后面一句的none of.前有一并列连词but（说明它与前面一句构成并列句，所以其后填them）。2.

13、 C. which D. when3. After living in Paris for fifty years he returned to the small town _ he grew up as a child.A. which B. where C. that D. when【查看答案】【参考答案】2. B3. B【答案解析】定语从句中有表示地点的先行词，而地点状语从句中则没有；定语从句的关系词根据需要可用介词+which来代替where，而地点状语从句则通常只能由where引导。因此第2题中无表示地点的先行词，是表示地点的状语从句，故填where，第3题中the small t

14、own是先行词，为定语从句，故填where，也可用in which替换。题组一 基础过关用适当的关系词填空1.(2019北京卷) Consequently, she succeeded in making a kind of candy only using natural sweeteners, _ can reduce oral bacteria.2.(2019全国卷II) Laurie Demerit，_ company provided the statistics for the report.3.

18、s differ from those of animals in the degree _ they can be controlled on purpose.A.with which B.to which C.of which D.for which【查看答案】【答案】B【解析】考查固定短语的用法。句意：人类的面部表情和动物的面部表情就可控制的程度来说是不一样的。本句是定语从句，先行词是the degree，to the degree是固定短语，意为到程度，关系词which在从句中作to的宾语，本句将从句中的介词to提至关系词which前面了。故选B。2.Gun control is a

19、subject_ Americans have argued for a long time.A.of which B.with which C.about which D.into which【查看答案】【答案】C【解析】考查动词短语的辨析。句意：对枪的控制是美国人一直争论的一个话题。argue about意为争论；argue with意为和争论，所以此处应用介词about。故选C。3.Eric received training in computer for one year, _ he found a job in a big company.A.after that B.after

20、which C.after it D.after this【查看答案】【答案】B【解析】考查非限制性定语从句的用法。在这个非限制性定语从句中，先行词是Eric received training in computer for one year这件事，关系词在从句中作介词after的宾语，所以关系词应用which。故选B。4.True friendship is like health, the value_is seldom known until it is lost.A.of it B.on whichC.of whom D.of which【查看答案】【答案】D【解析】考查介词+关系代

21、词结构。句意：真正的友谊犹如健康，直到失去时才知其可贵。此处不能用介词+指示代词结构；先行词为friendship，指物，故不能用whom；此处表示所属关系，故介词只能用of，所以B项不符合句意。故选D。【温馨提示】本题易误选A项或者C项。但是考生需要注意,用whom时先行词应指人；如选A,可在逗号后加上连词and。5.With more than 17 000 islands, _only 6 000 are inhabited, Indonesia is the worlds largest archipelago (群岛).A.on which B.for which C.of whic

22、h D.along which【查看答案】【答案】C【解析】考查介词+关系代词引导的定语从句。分析句子结构可知选C。of which中的which指17 000 islands,17 000 islands为先行词。6.

23、上长着许多灌木的房子对我说，那就是我将要待的地方。house是先行词，与roof是所属关系，故用whose引导；that was _ I would stay是told的宾语从句，该从句中that是主语，_ I would stay是表语从句，从句中缺少地点状语，所以用where引导。7. Our special thanks go to thousands of volunteers, without _ tireless work, none of these would be possible.A. which B. whom C. whose D. that【查看答案】【答案】 C【解

24、析】考查定语从句。句意：我们特别感谢数以千计的志愿者们，没有他们不知疲倦的工作，所有这些都不可能做到。volunteers与tireless work是所属关系，所以用关系代词whose，在从句中作定语。8.Have you known Jane for long?Not very long, _ we started to serve the World Expo in Milan.A. after B. before C. when D. since【查看答案】【答案】 D【解析】考查状语从句。句意：你认识Jane很久了吗？认识的时间不长，是从我们开始服务于米兰世博会时认识的。根据句意可知
