专题10定语从句-3年高考2年模拟1年备战2019高考精品系列之英语(Word版含解析)
【2019年高考命题预测】高考研究定语从句是英语三大类从句中最难的一类，其难点主要在于很多学生在学习时分不清先行词，不能正确使用关系代词、关系副词。
因此在学习定语从句时，务必搞清定语从句的概念、关系词的正确选择和使用情况等。
预测今后高考定语从句的考查还将是对关系代词和关系副词的考查。
【考点定位】2019考纲解读和近几年考点分布（1）考纲要求定语从句是高考的热点，对于定语从句考纲要求掌握以下内容：1.引导限制性定语从句的关系词；2.引导非限制性定语从句的关系词；3.限制性与非限制性定语从句的区别；4.介词+关系代词的用法；5.不定代词/数词+of which/whom引导的非限制性定语从句及其该结构与并列句的判断；6.关系词之间的异同现象及选用。
（2）命题规律一、主要考查关系代词和关系副词的正确运用，特别是它们在非限制性定语从句中的运用。
二、高考对定语从句的考查仍将不会单纯考查其语法结构，而是将其融入一定的语境中来考查考生的实际综合运用能力。
【考点pk】名师考点透析考点1：关系代词一览表关系词先行词从句成分例句备注关系代词who 人主语Do you know the man who is talkingwith your mother?whom, which和that在从考点2：that与which，who，whom的用法区别that和which的用法区别:在定语从句中，关系代词which和 that都可指物，一般情况下，可以互换使用。
但在下列情况下值得注意：(3) 当先行词由形容词的最高级或序数词修饰时，只能用that。
如：This is the most interesting book that I have ever read. 这是我读过的最有趣的书。
(4) 当先行词同时包括人和物时，只能用that。
如：Luxun and his works that we are familiar with are considered great. 人们认为我们所熟识的鲁迅及其作品都很伟大。
(5) 当先行词在定语从句中作表语时，只能用that。
如：This is a book that I have been looking for since last week. 这就是那本自上周以来我一直在寻找的书。
(3) 先行词为代词that或that所修饰时，只能用which。
如：I don’t take that which is too expensive. 我不要太贵的那一个。
who (whom) 和that的用法区别详解:在定语从句中，关系代词who (whom) 和that都可指人和物，在一般情况下，可以互换使用，但在下列情况下值得注意：一、用who (whom) 而不用that的情形(1) 在非限制性定语从句中的先行词指人时，只能用who (whom)。
如：My sister, who is studying abroad, sent me a beautiful present just before this Christmas. 我姐姐，她在国外学习，就在圣诞节前给我寄来了漂亮的礼物。
(2) 当定语从句对指人的先行词进行隔位修饰时，只能用who (whom)。
如：Do you know the girl in front of the blackboard who is speaking to the students? 你认识黑板前面正在给学生们讲话的那位女孩子吗？(3) 当先行词为people和those时，只能用who (whom)。

(4) 当先行词为one, ones, anyone, everyone, none, all(指人) 时，只能用who (whom)。

(5) 先行词指人，而关系代词在从句中作主语时，一般多用who。
如：The man who came here yesterday said he would come again in a few days. 昨天来这儿的那个人说过几天他会再来。
二、用that 而不用who (whom)的情形(1) 当先行词前面有形容词的最高级或序数词修饰时，引导词只能用that。
如：The tallest player that plays football for our team is from Shandong. 在为我们队踢足球的最高哪个运动员来自山东。
(2) 当先行词前面有only, some, any, no, every, little, few, much, all, very形容词修饰时，引导词只能用that。
如：He is the only student that said “no” to the teacher. 他是唯一的一个对老师说“不”的学生(3) 当主句是以who开头的特殊疑问句时，引导词只能用that。
如：Who is woman that you talked with just now? 刚才跟你谈话的那位妇女是谁？(4) the same as与the same thatthe same as所引导定语从句的内容与先行词同类而不同物；the same that表示所引导的从句内容与先行词同类同物，即：同一事物。
如：She is wearing the same coat that I lost a few days ago. 她正穿着我几天前所丢失的上衣。
(暗含：她偷了我的上衣)She is wearing the same coat as I lost a few days ago. 她正穿着跟我几天前所丢失的上衣同样的上衣。
(暗含：她所穿的上衣不是我所丢失的那一件)考点3 关系副词引导的定语从句1、关系副词一览表关系副词when 时间时间状语I will never forget the day when wemet there.可用onwhichwhere 地点地点状语This is the house where I was born.可用inwhichwhy 原因原因状语I can’t imagine the reason why heturned down my offer.可用forwhich②He’s got himself into a dangerous situation where he is likely to lose control over the plane．他发现他陷入了危险的境地，他有可能会失去对飞机的控制。
1．概述“介词+关系代词”引导的定语从句多用于正式文体，使用的关系代词一般是which，whom，它既可以引导限制性定语从句，又可以引导非限制性定语从句。
常见的有以下几种结构：(1)介词+关系代词Mandela was the black lawyer to whom 1 went for advice．=Mandela was the black lawyer whom 1 went to for advice．曼德拉是我寻求帮助的一位黑人律师。
(2)名词/代词/数词+介词+关系代词①Last Sunday I bought some books from the bookstore，three of which were English novels．=Last Sunday I bought some books from the bookstore，of which three were English novels．上个星期天，我从书店买回几本书，其中三本是英文小说。

定语从句-2019高考英语卓越专项训练精英版+Word版含解析
定语是对名词或代词起修饰、限定作用的单词、短语或句子，汉语中常用“……的”表示。
单词作定语一般前置,句子或短语作定语则需后置，当一个复合句中，作定语的是另外一个句子时，这个句子叫定语从句。
被修饰的名词，词组或代词叫先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
定语从句在高考中的考查重点：1. that与which引导的定语从句的区别；2. who、whom与whose引导的定语从句的区别；3. 关系副词where、when与why引导的定语从句的区别；4. 对“as”引导定语从句的考查；5. 对“介词+关系代词”的考查；6. the way 作先行词时,定语从句的引导词作状语用in which ,that 或者省略；7. 含有插入语的定语从句；定语从句的分类：限制性定语从句(restrictive attributive clauses)和非制性定语从句(non-restrictive attributive clauses)：限制性定语从句——修饰的名词或代词(即先行词)起到限定作用，表示“……的人(事物)”，一般说来如把从句去掉句子意思就不清楚，甚至失去意义。
像这样从句和主句关系十分密切，书写时不用逗号隔开的定语从句叫限制性定语从句。
非限制性定语从句(non-restrictive attributive clauses)：This is the book that you want.这就是你要的那本书。
(若把that you want去掉，意思就不够清楚。
)He is a man everyone respects.他是一个人人都敬重的人。
(若把从句去掉，句子就失去意义。
)【分析】上面两个句子中的从句很重要，说明所修饰词的意义不可或缺，是句子的主要组成部分。
