定语从句和名词性从句讲解
定语从句和名词性从句讲解作者：李宏福来源：《新高考·英语基础（高一）》2017年第08期高一语法的定语从句和名词性从句是高中英语教学的重点，也是学生学习的难点，同时又是高考考查的热点。
纵观近年各地高考试题，对两大从句的考查不是单纯考查其语法结构，而是把它融入到一定的语境中，考查学生的实际综合运用能力。
本文试图分析这两大从句的常见考点，帮助学生在学习中总结应对的策略。
一、定语从句的考点1.关系代词的用法（1）关系代词that和which的用法that和which在限制性定语从句中都可以做主语、表语或宾语，先行词均指物；做宾语时，均可省略。
在通常情况下，可以互换使用，但是that不能引导非限制性定语从句，which 可以引导非限制性定语从句。
命题角度主要以that与which指物时的区别为重点进行命制。
【例题】①You can borrow any book________you want to read in our school library.A.whichB.thatC.whoD.where【解析】答案是B。
先行词被all，every，no，some，any，（a）few，（a）little，much 等限定词修饰时，用that引导，不用which。
②The president of the World Bank says he has a passion for China，________he remembers starting as early as his childhood.A.whereB.whichC.thatD.when【解析】答案是B。
此处为非限制性定语从句，先行词是a passion，并在定语从句中做starting的宾语，that不能引导非限制性定语从句。
（2）关系代词as的用法关系代词as引导限制性定语从句时既可指人又可指物，只能替代由such，the same等修饰的先行词；as引导非限制性定语从句时，可放于句首，句中或置于句尾，而which则只能置于主句之后。
必修一定语从句讲义
高一英语必修一：定语从句讲义定语及定语从句一、定语句子中修饰名词或代词的成分叫做定语。
定语可以由形容词，名词，不定式，分词，动名词或从句来充当。
eg: She is a beautiful girl. （形容词）I met someone funny on my way to Beijing. （形容词）（修饰不定代词的定语后置）He is an English teacher. （名词）（名词作定语时一般用单数，例外的有sports, 如 a sports star）I have a lot of work to do. （不定式）The book written by a schoolboy is very popular now. （过去分词短语）We can see the rising sun. （现在分词） = the sun is rising.He is in the reading room. (动名词) = the room for readingThe boy who broke the window is Tom’s brother. （从句）注意：1.形容词作定语一般放在中心名词前面；但当形容词修饰的是不定代词时，要后置。
present (在场的), absent (缺席的)作定语时需要后置。
students present / absent2. 不定式做定语通常要放在被修饰的词后。
3 分词作定语时，即可放在所修饰词前，也可放在所修饰词后1）分词前置：单独的一个分词作定语，一般放在所修饰词前。
He is a retired worker.他是位退休的工人2）分词后置：在以下情况，分词放在所修饰词的后面i. 分词词组； There was a girl sitting there.有个女孩坐在那里ii. 个别分词如given, left；This is the question given.这是所给的问题iii. 修饰不定代词时There is nothing interesting.没有有趣的东西过去分词作定语与其修饰的词是被动关系，相当于一个被动语态的定语从句，表被动或已完成。

定语从句讲解(完整版)
定语从句讲解(完整版)定语从句是一种常见的语法结构，用于对名词或代词进行修饰和限定。
在英语中，定语从句的使用可以使句子更加丰富和准确。
下面，我将为您详细讲解定语从句的构成、用法和注意事项。
一、定语从句的构成定语从句由引导词、关系词和从句组成。
引导词通常是先行词，即被修饰的名词或代词；关系词用于引导定语从句，并将先行词与从句连接起来；从句则是对先行词进行修饰和限定的部分。
1. 引导词：先行词通常是名词或代词，它可以是主语、宾语或表语。
例如：The book that you gave me is very interesting.（你给我的那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）2. 关系词：关系词用于引导定语从句，并将先行词与从句连接起来。
关系词有who、which、that、whom、whose等。
例如： The book that you gave me is very interesting.（你给我的那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）3. 从句：从句是对先行词进行修饰和限定的部分。
从句中通常包含主语、谓语和宾语等成分。
例如：那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）二、定语从句的用法1. 限定性定语从句：限定性定语从句对先行词起到限定作用，即只有满足定语从句条件的名词或代词才是先行词的准确含义。
限定性定语从句通常紧跟在先行词之后，且不能用逗号与主句隔开。
例如： The book that you gave me is very interesting.（你给我的那本书很有趣。

(word完整版)高中英语定语从句用法详解文档
定语从句用法详解英语句子中用来修饰名词、代词或句子的从句叫做定语从句。
定语从句在句子中的作用相当于形容词，因此也被称为形容词性从句，它可以用来修饰一个名词或代词，也可用来修饰句子中的某个短语，甚至整个句子。
1.被定语从句修饰的词称为先行词。
2.引导定语从句的词被称为关系词，它包括关系代词和关系副词两种。
I 定语从句中关系词的分类及用法关系词不仅在先行词与定语从句之间起连接作用，而且作从句中的一个成分。
II定语从句的分类根据定语从句与先行词之间关系的紧密程度，定语从句可分为限制性定语从句、非限制性定语从句和间隔式定语从句。
1.限制性定语从句：限制性定语从句对先行词起修饰、限制与确定的作用，若去掉它，先行词便不能明确表示其所指对象，因此，限制性定语从句和它的先行词所指意义有着不可分割的联系，不能用逗号与先行词隔开。
1）He has two sons who work in the same company.他有两个在同一家公司工作的儿子。
2）I'll never forget the day when we first met each other.我将永远忘不了我们初次见面的那一天。
3）This is the factory where/in which I worked ten years ago.这是我十年前工作过的工厂。
2.非限制性定语从句：非限制性定语从句对先行词或主句起补充说明的作用，即使省去也不影响主句的语义完整性。
非限制性定语从句与先行词或主句之间常用逗号隔开。
Yesterday Jimmy left for Canada, where he had stayed for two years.昨天吉米动身到加拿大去了，他曾在那儿呆过两年。
We have three foreign teachers, two of whom are from America.我们有三个外教，其中两个来自美国。
