4、at which)you spent your holiday last year?去年你度假的那个地方叫什么名字？The reason why he was late for class was that he got up late.他迟到的原因是他起晚了。(二)“介词关系代词”引导的定语从句定语从句中的介词有时可置于关系代词之前，形成“介词关系代词”结构。关系代词通常是which和whom,which指物，whom指人。1介词which在所引导的定语从句中作时间状语、地点状语、原因状语等。Ill never forget the days on which we studied toge

5、ther.我永远忘不了我们一起学习的日子。This is the town in which Shakespeare was born.这就是莎士比亚出生的城镇。Can you explain the reason for which you were absent?你能解释一下你没来的原因吗？2“名词/代词/数词介词关系代词”结构常用来表示与先行词之间的从属关系，可以用whose结构代替。Please pass me the book，the cover of which/whose cover is blue.请把那本蓝色封面的书递给我。There are fifty students i

6、n our class,most of whom are from big cities.我们班有50个学生，其中大多数来自大城市。3关系代词前介词的选择。(1)看先行词与介词的搭配。The book has opened a window through which we can see a wonderful world outside.(through the window 通过/穿过窗户)书本打开了一扇我们能够看到外面精彩世界的窗户。(2)看从句谓语动词与介词的搭配。The university from which he graduated is supposed to be one

7、 of top universities in the world.(graduate from a university 大学毕业)他毕业的那所大学被看作是世界上顶尖大学之一。(3)看从句中形容词与介词的搭配。Her daughter has been admitted into Beijing University,of which she is very proud.(be proud of以为自豪)她女儿被北京大学录取了，为此她感到很自豪。(4)看定语从句的含义。Nowhere could he find his glasses,without which he could see n

8、othing.他找不到眼镜了，不戴眼镜，他什么也看不见。二、难点突破1部分“介词which”引导的定语从句可以转化为关系副词引导的定语从句。(1)在定语从句中作时间状语时用when。Well never forget the days in which/when we stayed in the beautiful village.我们永远不会忘记在那美丽的乡村待过的日子。(2)在定语从句中作地点状语时用where。The school in which/where my sister is teaching is in the charge of a young lady.我姐姐任教的那所学

9、校由一位年轻的女士掌管。(3)在定语从句中作原因状语时用why。The reason for which/why he was absent from class today is that he is ill.他今天没来上学的原因是他生病了。2scene,case,point,situation,conditions等表示“情况，方面”等的名词作先行词时，在定语从句中作状语常用where引导，亦可用“介词which”结构。He had to face the conditions where/under which pressure was heavy.他必须面对压力很大的情况。The sc

10、ene where/in which the bear comes at the hunter is frightening.熊朝猎人扑来的那一幕很吓人。3在定语从句中“介词which”结构不可以与普通关系代词或关系副词互换的情况。(1)介词which结构在定语从句中所作状语不表示时间、地点、原因时。Theres only one problem about which they disagree.仅有一个问题他们不同意。(2)有些“动词介词”短语，如look for,look after,take care of等，如果介词提前将会失去动词短语的意义时，介词不能提前变成“介词which”结构

11、。This is the very book(that)I am looking for.这正是我在找的书。名师点津关系代词和关系副词的选择：(1)明确定语从句的先行词是表时间还是地点。(2)分析句子结构，明确先行词在定语从句中所作的句子成分。(3)分析从句中的谓语动词。及物动词后面无宾语，就必须用关系代词；而不及物动词则要用关系副词。课堂达标验收.用适当的关系词填空1 I wont forget the night _ I got lost in the mountain.2He at last explained to us the reason _ he refused our offe

17、定语从句。由语境知答语是个强调句的省略句，补充完整为：It was in the house where I lived last year that I found Tom.。被强调部分是地点状语in the house，后接定语从句，live是不及物动词，不需要接宾语，where在定语从句中作地点状语。2I shall never forget the years _ I lived in the country with the farmers,_ has a great effect on my life.答案：when;which考查定语从句。第一个空引导定语从句修饰years，又在

18、从句中作时间状语；第二个空引导非限制性定语从句，在从句中作主语。3In the dark street,there wasnt a single person _ whom she could turn for help.答案：to句意：在漆黑的街道上，没有一个她能求助的人。turn to sb.for help“向某人求助”，这是一个固定句式，person为先行词，定语从句部分中she为主语，whom作turn to的宾语，该句to放在了关系代词的前面，关系代词只能用whom。本句的正常语序为“In the dark street,there wasnt a single person wh

19、om she could turn to for help”。4I dont like the way _ he treated the old.答案：that考查关系词的使用。定语从句缺少状语。先行词way以in the way的形式在从句中作方式状语。当“way”表示“方式、方法”在句中作先行词，后被一个定语从句修饰时，引导定语从句可用that，也可用in which，或什么都不用。5Many young people just cant live without the Internet,_ they depend on for whatever information they nee

20、d.答案：which考查定语从句。句意：许多年轻人离开网络就不能活，他们依靠网络获得需要的任何信息。which引导非限制性定语从句并在从句中作depend on的宾语，其先行词为the Internet。6When she was a small girl,her mother arranged for her to have extra classes on Saturday _ piano lessons are taught.答案：where考查定语从句。先行词为classes，定语从句piano lessons are taught不缺宾语或主语，所以先行词应该作状语，表地点用wher

21、e。7Is this the school _ you studied twelve years ago?答案：where考查定语从句。句意：这就是你十二年前就读的那所学校吗？本句中先行词为the school，定语从句中缺少地点状语，故用where，相当于in which。8“We went through a period _ communications were very difficult in the rural areas.”said Mo Yan.答案：when考查定语从句的关系词。先行词是period，定语从句中不缺少主语或宾语，因此period应该在定语从句中作状语，与介词

22、的搭配是in the period，相当于when。9Can you think of a situation _ this expression can be used?答案：where考查关系代词的选用。在这个定语从句中this expression can be used不缺少主语和宾语，所以不可以填which和that或省略，因此断定定语从句中缺少状语，where相当于in a situation。10 We all want to know the reason _ you left without a word.答案：why考查定语从句。whyfor which，引导reason后的定语从句，在从句中作状语。句意：我们都想知道你不辞而别的原因。课 时 作 业点此链接
