定语从句

课件29张PPT。定语从句讲解练习概 念什么是定语从句：
在复合句中，修饰某一名词或代词的从句叫定语从句。其作用是修饰主句中的某一名词或代词，修饰的名词或代词叫先行词。
e.g. Do you know the man （who came to see Xiaowang this morning? ）名 词定语从句先行词= e.g. There is somebody here (who wants to speak to you. )
这里有人要和你说话。 代词定语从句放在先行词之后，先行词由关系代
词或关系副词 引导，关系词放在它们中间。
关系代词：who, whom, that, which, whose
关系副词：when, where, why
e.g.
1. He is a man whom we should all learn from.
他是一个我们都应当学习的人
2. I still remember the day when I first came to 定语从句的翻译。 要 点：注 意：用 法：1 . 定语从句修饰人，用who that，（who和that一般可互换，有时可省去） 如人后有介词，则必须用whom .
e.g. The people (whothat) you were talking to were Japanese.
Is she the girl that sells flowers?He is a man that you can safely depend on. 他是一个你能依靠的人。
The girl to whom I spoken is my cousin.
The girl whothat I spoken to is my cousin.区别相似关系词由who，whom和whose引导的定语从句
who在从句中作主语，whom在从句中作宾语， whose在从句中作定语。
e.g.
1. This is the thief who stole my bike.
这就是偷我自行车的那个贼。
2. He is the boy whom you wanted to find.
他就是你想要找的那个男孩。 3. The girl whose mother is a doctor is waiting for you outside.
妈妈是个医生的那个女孩在外面等你。 2 . 修饰物用which that.
e.g. The train whichthat has just is for xi’an.
The pen thatwhich you gave me is very nice.
This is the question that we’ve had so much discussion about.
This is the question about which we’ve had so much discussion 用 法：3. when指时间，在定语从句中做时间状语
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.4. where指地点，在定语从句中做地点状语
(1) Shanghai is the city where I was born.
(2) The house where I lived ten years ago has been pulled down.
5. why指原因，在定语从句中做原因状语
(1) Please tell me the reason why you missed the plane.
(2) I don’t know the reason why he looks unhappy today.判断关系代词与关系副词重点关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词（who, whom, that, which, whose）； 先行词在从句中做状语时，应选择关系副词 （ where 地点状语，when 时间状语，why 原因状语） 。判断改错：
This is the mountain village where I visited last year.
This is the mountain village （which） I visited last year .
I will never forget the days when I spent in the countryside.
I'll never forget the days （which） I spent in the countryside.巩固练习1. Is this museum ___ you visited a few days ago?　
A. where　 B. that　C. on which　 D. the one
2. Is this the museum ____ the exhibition was held?
A. where　B. that　C. on which　D. the oneDA解释：
1: this museum作主语，the one代替主语作先行词，且作宾语，省去which.
2: the museum作状语。
判断改错（用横线表示出错误并改正。）　
　1. This is the mountain village where I visited last year.　
　2. I will never forget the days when I spent in the city.改
1：where改成which，因为the mountain village作宾语。
2： when改成which，因为the days作宾语。介词+关系代词引导的定语从句关系代词
