定语从句 2
初中定语从句2一、何时用关系副词when, where, why引导定语从句?when 引导定语从句:先行词是表示时间的名词而且是从句动作发生的时间时,用when引导定语从句。
I’ll never forget the day when (= on which ) I met you.This was the time when ( =at which ) he left for Beijing .We will put off the outing until next week, when(=in which) we won’t be busy.where 引导定语从句:先行词是表示地点的名词或含有地点意义的抽象名词而且是从句动作发生的地点时,用where引导定语从句。
This is the town where (= in which ) I spent my childhood.The table at which she is sitting is a new one.I’ll show you the point where you failed.why引导定语从句:先行词是reason并且从句是表示结果时,用why引导定语从句。
This is the reason why ( = for which ) I didn’t come here.The reason ________________ she gave was not true.特别注意:当定语从句缺主语或宾语才直接用which或that引导定语从句。
The library _______________________ students often study was on fire last night.The library, _______ was built in the 1930s,needs repairing.The library _______________ you visited yesterday was built in 1990.I’ll never forget the day _____________________ we first met in the park.I’ll never forget the time ______________ I spe nt on campus.I’ll never forget the time ______________ was spent with you.二、介词+关系代词应注意的情况1. who、that 不能用与介词之后The man who/whom you spoke to was a scientist. The man to whom you spoke was a scientist. The city that/which she lives in is far away. The city in which she lives is far away.2. 在固定短语中介词不能提前Is this the watch that you are looking for? The old man whom I am looking after is better .三、如何确定介词?把先行词接到从句谓语后面去,看需要什么介词1、看定语从句中动词与介词的搭配He is the man _____ whom I think you can depend.The house ____ which he paid 100,000 yuan is very beautiful.2、看定语从句中形容词与介词的搭配He referred me to some reference books ______ which I am not very familiar.This is the hero _____ whom we are proud.3、根据先行词判断,所用的介词与先行词搭配The school ______ which I study is the No. 11 high school.The rate/speed ______ which wild animals are being destroyed has increased.The age______ which children can go to school is seven.4.根据从句中动词与先行词搭配来选用介词,这时是两者兼顾。

关系副词when,where,why引导的定语从句
关系副词when,where,why引导的定语从句关系副词when, where, why引导的定语从句关系副词when, where, why引导的定语从句1,基本用法定语从句除可用关系代词引导外,还可用关系副词when, where与why来引导,它们的区别是:when用于指时间,where用于指地点,why用于指原因。
when, where, why 在定语从句中均用作状语。
如:1980 was the year when he was born. 1980是他的出生年。
This is the town where I was born. 这就是我出生的城市。
This is the town where I was /SPAN>These are the reasons why we do it. 这些就是我们这样做的理由。
2. 先行词问题关系副词when和where的.先行词是表示时间(如the day, the days, the time, the year等)和地点(如the place, the house, the factory, the station等)的一类词,而关系副词why的先行词通常只是whythe reason(s)。
另外,when和where可引导限制性和非限制性定语从句,而why则只用于引导限制性定语从句,不用于引导非限制性定语从句。
3. 一点注意注意不要以为在时间名词后就一定用关系副词when,在地点名词后就一定用关系副词 where,在表示原因的the reason后就一定用关系副词why。
到底选用关系副词还是关系代词,关键是看它们在定语是用作状语(用关系副词)还是用作主语或宾语(用关系代词)。
如:Don’t forget the time (that) I’ve told you. 不要忘记我告诉你的时间。
(that用作told的宾语)I’ll never forget the days when I worked with you. 我永远不会忘记我与你共事的日子。

高中英语教学中关系副词引导的定语从句
高中英语教学中关系副词引导的定语从句关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。
名词+关系副词+定语从句,引导定语从句的关系副词主要有where,when和why。
why只能引导由名词reason作先行词的定语从句。
关系副词where,when,why 所引导的定语从句用来说明先行词所发生的地点、时间和原因,因此关系副词首先是起连接主从句的作用,其次在定语从句中作地点、时间或原因状语。
一、where的语法功能相当于in(on,at,from……)+地点名词或表示地点的副词there,here等。
例:①As a child,he used to work hard and help his father on the small farm where/on which he lived. (where=on the small farm)当他还是一个小孩的时候,他就习惯了艰苦的劳动,并帮助他的父亲在他们所生活的农场干活。
②This is the village where/in which I was born.(where=in the village)这就是我出生的村庄。
二、when的语法功能相当于in(on,at,from……)+时间名词或表时间的副词。
例:①This was a time when/at which there were still slaves in the U.S.A.这是一个在美国仍处在奴隶制度的时代。
when=at that time在从句中作时间状语。
②I’ll never forget the day when/on which I left for college with my father.我永远不会忘记我和父亲动身去大学的那天。
when=on that day.三、why引导的定语从句主要用来限定reason的内容,why=for which。
whenwherewhy引导的定语从句的用法
[解析] 本题中下划线处所引导的限定性定语从句修饰表示时间的先行词hours, 其引导词在该定语从句中充当时间状语, 因此只能填入关系副词when.
[考题3] It was an exciting moment for these football fans this year, ____ for the first time in years their team won the World Cup. (2000北京、 安徽春)
= This is a hall in which the medical conference will be held.
这是礼堂, 医学会议将在此召开。
2. 并非先行词表示时间或地点时都分别用when或where来引导相应的定语从句, 若关系词在修饰表示时间或地点的先行词的定语从句中充当主语、 宾语等而不是状语时, 需用which或that引导相应的定语从句。例如: Do you still remember the days which/that we spent together in school? 你还记得我们一起在学校度过的那些日子吗?
A. that B. while C. which D. when
[答案] D
[解析] 本题中下划线处所引导的非限定性定语从句修饰表示时间的先行词moment, 其引导词在该定语从句中充当时间状语, 因此只能填入关系副词when.
[考题4] After living in Paris for fifty years he returned to the small town ____ he grew up as a child. (1996)
2. 关系副词where引导定语从句(包括限定性定语从句和非限定性定语从句)修饰表示地点的先行词, 在定语从句中充当地点状语。例如: This is the office where he worked. 这就是他工作过的办公室。// She is going to live in Macao, where she has some close friends. 她要到澳门去定居, 在那里她有几个密友。
when,where,why引导的定语从句
when,where,why引导的定语从句when,where,why作为定语从句的引导词,总称为关系副词。
下面用句子合并的方法分析它们的使用。
一、where引导的定语从句请分析下面两个简单句:句①I know a garden.句②You can find wild strawberries there.把句②变为句①的定语从句,句①中的agarden做定语从句的先行词。
在句②中there指句①中提到的agarden也就是定语从句的先行词,there在句中做地点状语,因此要用where 引导定语从句,代替句②中的there,也就是说there就不能出现在定语从句中了。
由此得到句③I know a garden where you can find wild strawberries.句②还可以写作句④You can find wild strawberries in it(it指句①中的garden,“在花园中”要使用介词短语in the garden)。
把句④变为句①的定语从句,因为it做介词in 的宾语,先行词是agarden,指物。
在这种定语从句中介词常常提到定语从句的开始,这时关系代词只能使用which替代it,it就不能在定语从句中出现了。
由此得到句⑤即:I know a garden in which you can find wild strawberries.请把下面每组的两句话合并为一句,把第二句话变为第一句的定语从句。
第一组:This is the village.I was born there.→This is the village where I was born.第二组:The lab is not far from here.The chemist often does experiments there.→The lab where the chemist often does experiments is not far from here.二、when引导的定语从句请分析下面两个简单句:句①We shall remember the days.句②We studied together then.把句②变为句①的定语从句,句①中的the days做定语从句的先行词。
定语从句(Ⅱ)——where,when,why,“介词+whichwhom”引导的定语从句
1、关系副词where的用法(1)where的先行词大多是地点名词,在定语从句中作地点状语从句。
This is the school where/in which my father once worked.这是我父亲曾经工作过的学校(2) where的先行词还可以是抽象名词, 如stage,case, situation,position等。
例 They have reached the stage where/at which they will separate 他们已经到了将要分手的地步了。
2、关系副词when的用法(1)when的先行词是时间名词,在定语从句中作时间状语。
例 Do you remember the day when/on which we first met each other ?你还记得我们第一次见面的那一天吗?(2)when的先行词还可以是抽象名词, 如break, interval等。
例There is a long break between the two classes when/at which we can drink some water .在两节课之间有一个长的休息时词,在这期间我们可以喝点水。
3、关系副词why的用法why的先行词是reason,在定语从句中作原因状语。
reason作先行词时,若引导词在从句中作主语或宾语,定语从句要用that或 which引导。
例 I don ' t know the reason why/for which my good friend , jack ,looks unhappy today.我不知道我的好朋友杰克为什么今天看上去不高兴。
(1) The reason why…..是why引导的定语从句,Why在从句中作原因状语,Why可替换成 for which。
(2) The reason that……是that引导的同位语从句,that不作成分,that后面的内容说明 reason的内容。
关系副词whenwherewhy 引导的定语从句
关系副词when,where,why 引导的定语从句。
1.用来修饰名词或名词词组及代词的从句叫定语从句。
被定语从句修饰的词叫先行
词,引导定语从句的词叫关系词,关系词一般紧跟在先行词后面引导定语从句。
其中关系词分关系代词和关系副词,关系副词起着副词和连词的作用,在从句中作状语,表示地点、时间及原因。
2.关系副词的用法不受限制性。
非限制性定语从句的影响。
3.(1)when的先行词是表示时间的名词,在从句中作时间状语。
例如:I’ll never forget the day when AAI first meet him.
但如果定语从句的谓语动词是及物动词,及时间名词做了宾语或主语,则不能用when.
例如:The date which is our National Day is important to us all.(做主语)
We’ll never forget the days that/ which we spent together.(做宾语)
(2)where 的先行词是表地点的名词,在从句中作地点状语。
但地点名词在从句中不作状语,则应用相应的关系代词。
(3)why 的先行词为 reason,且从句是说明原因引出的结果的,则用why; 如从句是详细说明原因内容的则应为同位语,用that.
例如:None of us know the reason why she cried.(说明原因)
The reason that he has got a bad toothache is known to us all.(说明原因内容)。
怎么区别why引导的定语从句和同位语从句?
when,where 和why 引导的定语从句和同位语从句之区别when , where 和whey 既可以引导定语从句,也可以引导同位语从句,它们的相同点是在两种从句中都可以充当状语成分。
不同点是:when , where 和why 作关系副词引导定语从句时,有跟它们含义相应的先行词,如when的相应先行词是表示时间的名词,where 的相应先行词是表示地点的名词,why 的相应先行词是表示原因的名词。
当when , where 和why作连接副词引导同位语从句时,则没有与它们含义相应的先行词。
试比较:I'll never forget the day when ( = on which ) we met for the first time . ( 定语从句)I have no idea when we met for the first time ( 同位语从句)The office where ( = in which ) you work is here . ( 定语从句)Then arose the question where we were to get so much money . ( 同位语从句)The reason why ( = for which ) he did not come is quite clear . ( 定语从句)Xiao Wang has solved the problem why the TV was out of order . ( 同位语从句)以上例句中when , where 和why 作关系副词引导定语从句时,可以改为“介词+ 关系代词which”来引导;而引导同位语从句的when , where 和why 就不能这样改。
由此可知,why引导的若是同位语从句,先行词就不会是reason或其同义词;若是reason或其同义词作先行词,就一定是定语从句。
when、where和why关系副词的用法.doc
when、where和why关系副词的用法在英语中,引导定语从句的关系副词主要有when,where, why,它们在从句中分别可以作时间状语、地点状语和原因状语。
When的用法先行词指时间When可以引导限制性和非限制性定语从句,其先行词需是表示时间的名词,如day, year, time等。
如:I’ll never forget the day when I met you.注:这里的先行词是表示时间的名词day,所以要用when 引导定语从句。
这里when作从句的时间状语,修饰谓语动词met.My favorite season is spring, when the earth seems born again.注:这里是when引导的非限定语从句,先行词是表示时间的名词spring。
We will put off the outing until next week, when we won’t be so busy.注:这里的when引导的是非限制性定语从句,先行词是表示时间的短语next week.关系副词when在从句中作时间状语总之反复强调when是在定语从句中作时间状语。
换句话说,若定语从句不是缺少状语,而是缺少主语或宾语,那么即使先行词是表示时间的名词,也不能用when而要用which 或that来引导定语从句。
因为when来引导定语从句的前提条件是:when必须在其引导的定语从句中作时间状语。
如:1. I’ll never forget the time which I spent on campus.2. I’ll never forget the day when we first met in the park.注:两句话中,尽管先行词分别是表示时间的名词time 和day,但用的关系词不同。
第一句中,由于定语从句的谓语spent缺宾语,因此关系词要充当这一宾语,故要用which。
定语从句(Ⅱ)(关系副词(when, where, why)
定语从句(Ⅱ)(关系副词(when, where, why)以及介词+whic h/whom引导的定语从句)2.“介词+关系代词”引导的定语从句在“介词+关系代词”引导的定语从句中,关系代词只能用which或whom,不能用that.先行词指物时,用which;先行词指人时,用whom.1)介词选择的三原则:①介词根据从句中谓语动词的搭配习惯而确定。
This is the book on which I spent 5 yuan.This is the book for which I paid 5 yuan.This is the book from which I learned a lot.This is the book about which Tom often talks.②介词根据先行词的搭配习惯而确定。
I remember the day on which I joined the party.I remember the days during which I lived here.I remember the months in which I stayed there.③介词根据从句所表达的意义而确定。
My computer, without which I can’t play computer games, crashed yesterday.昨天我的电脑(系统)瘫痪了,没有它我不能玩电脑游戏。
2)介词可后移,此时关系代词可省略(省略时介词必须后移)。
This is the book for which you asked.这是你要的那本书。
This is the book (which/that you asked for.3)在“介词短语+关系代词”结构中,若介词短语表示位置,则定语从句往往用倒装语序。
常用的这类短语有:at the foot of, at the back of, in front of , on the top of等。
定语从句中关系副词的用法
定语从句中关系副词的用法关系副词,是联系先行词和定语从句的词,属于副词。
定语从句中的关系副词有三个:when, where和why,它们在定语从句中分别作时间、地点和原因状语。
其句法结构如下:?1.表时间的名词+ when + 定语从句?when指时间,在定语从句中作时间状语。
例句:I still remember the day when I first came to Beijing. ????? I’ll never forget the day when I joined the army.? 2.表地点的名词+ where + 定语从句? where指地点,在定语从句中作地点状语。
例句:The factory where his father works is in the west of the city. ????? This is the house where I lived two years ago.? 3.表原因的名词reason + why + 定语从句(why只用于reason之后的限制性定语从句中,在定语从句中作原因状语。
)例句:That is the reason why I did the job.(在现代英语中why可以省略)? 上句也可以这样表示:That is the reason I did the job.?又如:?This was the reason (why )we raised the temperature.关系副词在定语从句中的用法看似简单,以下注意点不可忽视:1)“when”、“where”和“why”的运用取就于表时间的名词、表地点的名词和表原因的名词reason在定语从句中所作的成分,比较下面的几组句子:*I will never forget the day when I first met you on the beach.*I will never forget the days which/that we spent together in Xueyao Middle School.**This is the hospital where my mother works.**This is the hospital which/that we visited the day before yesterday.***The reason why he did not go to school is that he was ill.***This is the reason which/that he gave his boss in the office .2) “when”、“where”和“why”都可以替换成“介词+ which”,介词的选用取就于先行词和定语从句中的动词。
高一英语定语从句---关系副词的用法(含例句及解析)
定语从句---关系副词的用法当引导定语从句的关系词在从句中做时间、地点、原因状语时,应使用关系副词when, where, why。
关系副词的作用如下:①指代表是时间、地点、原因的先行词。
②在从句中充当句子成分---状语。
③起连接作用,的主句和定语从句连接起来。
一、关系副词引导定语从句。
1.when引导的定语从句。
when表示时间,代替先行词并在定语从句中作时间状语,其先行词往往是表示时间的名词,如time,day,week,year等。
eg: We will never forget the day when we flew at an altitude of 6000 meters in the sky.我们永远忘不了在6千米高空飞行的那一天。
误区警示当先行词是时间名词时,定语从句既可用when引导,也可以用that 或which引导,关键看关系词在从句中作何种成分。
若关系词在定语从句中作状语,则用when引导; 若关系词在定语从句中做主语或宾语,则用that或which引导。
eg: Do you still remember the days when we chatted with each other all night?你还记得我们整夜聊天的那些日子吗?(when在从句中作状语)Do you still remember the days that /which we spent together on thefarm?你还记得我们在农场一起度过的那些日子吗?(that/which做spend的宾语)2.where引导的定语从句where表示地点, 代替先行词并在定语从句中做地点状语,其先行词往往是表示地点的名词,如place , factory,house, village等或表示抽象地点的名词,如position, point, case , stage,situation,atmosphere 等。
定语从句(Ⅱ)(关系副词(when,where,why)
定语从句(Ⅱ)(关系副词(when, where, why)以及介词+whic h/whom引导的定语从句)1. 由关系副词(when, where, why)引导的定语从句。
关系副词用法例句注意when 其先行词是表示时间的名词,如time ,day ,hour, year等,when代替先行词在从句中作时间状语I still remember theday when I first methim.我仍然记得第一次见到他的那一天。
若时间名词后面的定语从句的引导词在从句中作主语或宾语,则改为which或that.Eg: This is the day (whic h/that)he will never forget.where 其先行词往往是表示地点的名词,如place,room , house ,street ,area 等,where代替先行词在从句中作地点状语I visited the farmwhere a lot of cowswere kept.我参观了那家养了好多奶牛的农场。
若地点名词后面的定语从句的引导词在句中作主语或宾语,则改为which或that.Eg : This is the place (which/that)he visited before.why 常用在先行词reason后,代替先行词在从句中作原因状语,也可用for whichI don’t know thereason why he looksunhappy today.我不知道他今天看上去不高兴的原因。
若reason后的定语从句的引导词在从句中作主语或宾语,则改为which或that.Eg: I don’t believe the reason(which/that)he gave me.2.“介词+关系代词”引导的定语从句在“介词+关系代词”引导的定语从句中,关系代词只能用which或whom,不能用that.先行词指物时,用which;先行词指人时,用whom.1)介词选择的三原则:①介词根据从句中谓语动词的搭配习惯而确定。

关系副词
w h e n w h e r e w h y引导
的定语从句
集团标准化工作小组 [Q8QX9QT-X8QQB8Q8-NQ8QJ8-M8QMN]
关系副词when,where,why引导的定语从句。
1.用来修饰名词或名词词组及代词的从句叫定语从句。
被定语从句修饰的词叫先行词,
引导定语从句的词叫关系词,关系词一般紧跟在先行词后面引导定语从句。
其中关系词分关系代词和关系副词,关系副词起着副词和连词的作用,在从句中作状语,表示地点、时间及原因。
2.关系副词的用法不受限制性。
非限制性定语从句的影响。
3.(1)when的先行词是表示时间的名词,在从句中作时间状语。
例如:I’llneverforgetthedaywhenAAIfirstmeethim.
但如果定语从句的谓语动词是及物动词,及时间名词做了宾语或主语,则不能用when.
例如:ThedatewhichisourNationalDayisimportanttousall.(做主语)
We’llneverforgetthedaysthat/whichwespenttogether.(做宾语)
(2)where的先行词是表地点的名词,在从句中作地点状语。
但地点名词在从句中不作状语,则应用相应的关系代词。
(3)why的先行词为reason,且从句是说明原因引出的结果的,则用why;如从句是详细说明原因内容的则应为同位语,用that.
例如:Noneofusknowthereasonwhyshecried.(说明原因)
Thereasonthathehasgotabadtoothacheisknowntousall.(说明原因内容)。
