Unit5 定语从句【2019人教版高中英语选择性必修三Unit5 Poems语法知识】
Unit5 定语从句【2019人教版高中英语选择性必修三语法知识】Unit5 Poems定语从句是由关系代词或关系副词等引导的从句,其作用是作定语修饰主句的某个名词或代词,有时也可用来说明整个主句或主句的一部分,相当于形容词。
定语从句的三要素:先行词、关系词、关系词在从句中作某种成分。
1.定语从句的分类(1)限制性定语从句对先行词起修饰和限定的作用,如果把它去掉,主句就不能表达明确的含义,先行词与关系词之间不用逗号隔开。
People who take physical exercise usually live longer.进行体育锻炼的人通常更长寿。
(若把从句去掉,主句就失去了意义)(2)非限制性定语从句对先行词或主句起补充说明作用,把它去掉后,主句的意义仍完整且不受影响,常用逗号与先行词或主句隔开。
His daughter, who is in Boston now, is coming home next week.他的女儿现在在波士顿,下个星期回来。
(若把从句去掉,主句意义仍然完整)2.关系代词引导定语从句定语从句中,常用的关系代词有that, which, who, whom, whose , as.(1)指人: who,whomThis is the stranger who helped us today.这就是那位今天帮助过我们的陌生人。
Lily is the person with whom I am working.莉莉是同我一起工作的人。
(2)指物:whichIt was a prison from which no one escaped.那是一座任何人都逃不出去的监狱。
Julie is good at German, French and Russian, all of which she speaks fluently.朱莉擅长德语、法语和俄语,这些语言她都说得很流利。

第五单元语法突破语法知识精讲Grammar定语从句(Ⅱ)一、关系副词引导的定语从句1.when引导定语从句的用法(1)当先行词是表示时间的名词(如time,day,year,month,week等),且关系词在从句中做时间状语时,定语从句用when引导。
(2)when可以换成“介词+which”。
I still remember the time when(=in which) I was in college.我仍然记得我上大学的那段时光。
I have forgotten the exact date when(=on which) this country became independent.我忘记这个国家独立的确切日期了。
特别提醒当先行词是表示时间的名词时,既可以用when引导定语从句,也可以用that或which引导定语从句,关键要看关系词在定语从句中做何种成分。
若关系词在定语从句中充当状语,则用when引导;若关系词在定语从句中充当主语或宾语,则用that或which引导。
Do you remember the days that/which we spent together on the farm?你记得我们一起在农场度过的那些日子吗?(that或which做spent的宾语)Do you remember the days when we chatted with each other all night?你记得我们整夜聊天的那些日子吗?(when在从句中做状语)2.where引导定语从句的用法(1)当先行词是表示地点的名词(如place,room,mountain,airport等),且关系词在从句中做地点状语时,定语从句用where引导。
(2)where可以换成“介词+which”。
This is the hotel where(=in which) they stayed.这就是他们住过的旅馆。
Unit5语法定语从句：关系副词用法PPT课件
与when易混淆的介词
介词短语中，介词与名词构成介宾结构，表示该名词 所处的时期或状态。
时间状语从句中，when引导的从句修饰主句中的时 间名词，表示该时间点或时间段的具体时间。
例如：在“I will go to the party when my exam is over.”中，“when my exam is over”是时间状语从 句，修饰“I will go to the party”，表示去派对的时 间。而在“I will go to the party in June.”中，“in June”是介词短语，表示派对的时间。
描述条件
当主句描述一个条件或情况时， 可以使用where引导定语从句。 例如：“This is the company where I met my wife.”
只用why的情况
描述原因
当主句描述一个原因或动机时，可以使用why引导定语从句 。例如：“I understand why you are upset.”

定语从句20.1 定语从句的概述用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫做定语从句。
定语从句（Attributive Clause）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。
关系代词有：who, whom, whose, that, which等。
关系副词有：when, where, why等。
20.2. 关系代词引导的定语从句20.2.1 关系代词关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。

20.2.2 关系代词的用法20.2.2.1 关系代词who的用法A. who 的先行词必须是人，在从句中可以担任主语，往往也可以代替在从句中担任宾语的whom，但是它前边不能有介词，如果带了介词就必须用宾格的whom：（介词+whom）·This is the teacher who teaches us mathematics.·She is the girl who (whom) I met at the party.（可以替代）·She is the girl whom (who) I went there with.（可以替代）·She is the girl with whom I went there.（不可替代）B. who, that在很多情况下可以通用，但是有些情况只能用who：a. 先行词是one, ones, anyone的时候宜用who。
