定语从句详细讲解与习题

一．定语从句：定语从句是一种在句子中起修饰作用的从句，用于修饰一个名词或代词，就像一个形容词一样，让这个名词或代词的信息更加具体。

1. 基本结构---定语从句通常由关系代词（如who, whom, whose, which, that）或关系副词（如when, where, why）引导。

例如：--- The book that/which I bought yesterday is very interesting.（我昨天买的那本书非常有趣。

）其中，“that/which I bought yesterday”是定语从句，修饰先行词“the book”，“that/which”引导词，在从句中作宾语，指代“the book”。

2. 关系代词的用法--- who/whom：用于指人。

“who”在从句中做主语，“whom”作宾语。

---例如：The man who helped me is my teacher.（帮助我的那个人是我的老师。

）这里“who”在从句中做主语，不能省略；而在句子“The boy whom I met yesterday is my friend.”（我昨天遇到的那个男孩是我的朋友。

）中，“whom”作宾语，在口语中也可以用“who”来代替，并且可以省略。

--- whose：表示所属关系，意为“……的”，既可以指人也可以指物。

-例如：I know the girl whose mother is a doctor.（我认识那个女孩，她的妈妈是一名医生。

）“whose mother”在从句中做主语，修饰“the girl”；对于物，“The house whose windows are broken needs to berepaired.”（窗户破了的那所房子需要修理。

）--- which：用于指物，在从句中可以作主语或宾语。

---例如：The movie which we watched last night was really exciting.（我们昨晚看的电影真的很刺激。

(word完整版)高中英语语法定语从句讲解及练习

高中英语语法：定语从句定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。

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。

关系代词有：who, whom, whose, that, which等。

关系副词有：when, where, why等。

注意：关系代词和关系副词处在先行词和定语从句之间，起着连接主从句、指代先行词和在从句中作句子成分的三重作用。

一、关系代词that, which, who引导的定语从句二、关系代词whose引导的定语从句关系代词whose为关系代词who的所有格形式，用作名词的限定语，whose引导的定语从句既可为限制性的，也可为非限制性的。

先行词既可为人，也可为物，whose和它所修饰的名词在定语从句中可作主语及动词或介词的宾语。

例如：This is the scientist whose name is known all over the world.The room whose window faces south is mine.He has written a book whose name I’ve forgotten.=He has written a book the name of which I’ve forgotten.四、判断关系代词与关系副词先把主句和定语从句分开，再找出定语从句所修饰的名词/代词（即先行词），然后放入定语从句中，看看这两者的搭配情况。

1）如果定语从句和该先行词可以直接相连，且在从句中充当主语/宾语/表语的话，则用关系代词。

This is the city (which/that) you visited last year.2）如果定语从句和该先行词无法直接相连，必须另外多加上介词，并在定语从句中充当状语时，则使用关系副词。

This is the city where you stayed last year.选择：1. Is this museum ___ you visited a few days age?A. whereB. thatC. on whichD. the one2. Is this the museum ____ the exhibition was held.A. whereB. thatC. on whichD. the one五、限制性和非限制性定语从句1）定语从句有限制性和非限制性两种。

定语从句知识点汇总(原创含练习及答案)

三大从句——定语从句句子的成分定语从句，在一个复合句中作定语修饰某一个名词或代词，因此被称作定语从句；又因作定语的往往是形容词，所以定语从句又称形容词性从句。

定语从句是指一类由关系词引导的从句，往往位于被它修饰的词或词组之后。

被定语从句修饰的词或词组称作“先行词”，引导定语从句的词称作“关系词”，“关系词”又分为“关系代词”和“关系副词”。

·关系代词：that which who whom whose as·关系副词：when where why从句结构：从句是一个将关系词提前到句首的陈述句，即将关系词还原后变为一个完整的陈述句。

定语从句又分为“限制性定语从句”和“非限制性定语从句”，限制性定语从句起限定作用，修饰特定的名词或代词；而非限制性定语从句只起到补充说明某种信息的作用。

·限制性定语从句：从语义上看，限制性定语从句主要起限定作用，只能修饰名词或代词，如果删去限制性定语从句，整个句子表意会不完整甚至不通顺；从结构上看，限制性定语从句往往紧跟先行词，并且一般不用逗号隔开。

·非限制性定语从句：从语义上看，非限制性定语从句主要起补充说明的作用，可以修饰名词、代词、短语或句子，在句子中不充当成分，缺少也不会影响全句的理解。

从结构上看，它与主句之间往往用逗号隔开；若将非限制性定语从句放在句中，其前后都需要用逗号分隔。

做题技巧：·判断句子是否为复合句（长难句分析课时内容）·判断从句是否充当定语，若是则下一步；否则判断是否为剩下两种从句·判断先行词是人还是物，抑或整个句子·确定先行词在从句中所作的成分·确定关系词，从句缺成分选关系代词（没有what！）；反之选关系副词（没有how！）·关系代词关系代词所修饰的先行词在从句中充当的成分that人/物主语/宾语/表语which物/句子主语/宾语/表语who人主语/宾语/表语whom人宾语whose人/物定语（先行词的所有格）as人/物/句子主语/宾语/表语·关系副词关系副词所修饰的先行词在从句中充当的成分when时间时间状语where地点/抽象地点地点状语why reason原因状语注意事项（考点）：·只能用that的情况（先行词具有唯一性，绝对性）①当先行词被形容词最高级或序数词所修饰，或先行词本身是形容词最高级或序数词时，只能用that②当先行词是指物的不定代词或被这些词所修饰时，只能用that③当先行词被the only,the very（正是，恰恰）,the last,the same等含“唯一”意义的词修饰时，只能用that④当主句是以which,who引导的特殊疑问句或强调句型时，能用that时，为避免重复只能用that⑤当主句是there be或here be结构，且定语从句修饰指物的主语时，只能用that⑥当先行词既含有人也含有物时，只能用that⑦在双重限制性定语从句中，如果一个从句用who或者which引导时，为避免重复，另一个从句只能用that引导⑧当先行词指物且为主句的表语或关系代词是从句的表语时，常用that而不用which·只能用which的情况①当先行词指物且关系代词在从句中作介词的宾语，且介词在关系代词前时，只能用which，当介词和从句中的谓语构成固定的动词短语（如look after,look for,look forward to,take care of等）时，一般不能将其拆分开提前。

3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。

定语从句知识要点及练习

定语从句知识要点及练习定语从句知识要点及练习（⼀）定语从句在句中起定语作⽤，修饰某⼀名词或代词。

定语从句所修饰的词叫先⾏词，定语从句放在先关系代词的作⽤：1) 连接作⽤(引导定语从句，连接从句和主句)2) 替代作⽤(在从句中替代前⾯的先⾏词或整个句⼦)3) 成分作⽤(在从句中必须要担任⼀个成分)I.关系代词在定语从句中的具体⽤法1. who指⼈, 在从句中作主语(或宾语)．The girl who took you to my place is my friend.2.whom指⼈, 在从句中作宾语．The young men whom/who he employs are always complaining about their long hours．3.whose表⽰所属关系, 指⼈或指物, 在从句中作定语．The film is about a spy whose wife betrays him．4.that指⼈或指物, 在从句中作主语或宾语．All the apples that fall down are eaten by the pigs．The young lady that wears a blue blouse is a singer．5.which指物, 在从句中作主语或宾语．The stairs which lead to the language lab are rather slippery．II.限制性和⾮限制性定语从句根据定语从句与先⾏词的关系是否紧密, 可分为限制性定语从句和⾮限制性定语从句。

限制性定语从句往往紧跟在先⾏词后，不使⽤逗号分开, 翻译成中⽂时, ⼀般把定语从句翻译在被修饰词(即先⾏词) 前⾯。

⽽⾮限制性定语从句，⼀般使⽤逗号隔开,可把定语从句翻译在被修饰词(即先⾏词) 前⾯, 也可以翻译在其后, 作为附加说明．有时, 对两者的理解还会产⽣歧义。
