限制性定语从句复习
概念引入
    定语从句是我们从初中学到高一,又从高一学到高二,可能是出现最频繁的语法项目,在这个单元里,我们复习一下定语从句的用法,重点复习运用限制性定语从句时的注意要点。
    先看下面句子:
    1. I know you’re dying to hear all about my life here, so I’ve included some photos which will help you picture the places I talked about.
    2. The boys who had never come across anything like this before started jumping out of the windows.
    3. We walked for two and a half hours to get there — first up a mountain to a ridge from where we had fantastic views and then down a steep path to the valley below.
4. The only possessions I could see were one broom, a few tin plates and cups and a couple
of jars.
这些句子中斜体词部分就是定语从句,其中句1中包括两个定语从句: which引导的修饰photos; the places后的I talked about是省略了引导词的定语从句,修饰the places。句2中who引导的定语从句修饰boys;句3中是where引导的定语从句修饰a ridge;句4中I could see是省略了引导词that的定语从句修饰possessions。
下面我们就来对限制性定语从句的用法进行梳理和总结。为了不影响分析,下文中简单的句子,就不译成汉语了
用法讲解
定语从句及相关名词的定义
1. 什么是定语从句?
    指在句子中起定语作用,修饰句中的名词或代词的从句。定语从句包括限制性定语从句和非限制性定语从句两种。
2. 先行词:
即被修饰的名词、代词或短语,定语从句通常置于在先行词之后。
3. 引导词:
定语从句的引导词也称为关系词,分为关系代词和关系副词两种,放定语从句前,引出定语从句。关系代词和关系副词在定语从句中作一定的成分。
关系代词:who, whom, whose, that, which, as
关系副词:when, where, why

选择关系代词的步骤:
1. 到定语从句和先行词;
2. 把先行词放定语从句中确定要填的关系代词或副词作什么成分,注意介词的位置;
3. 确定是否是特殊用法;
4. 选择合适的关系代词或关系副词。
试填细解
试在下面句子中填入关系词:
1.This is the detective ____ came from London.
2.The lady ____ they wanted to visit is a scientist.
3.The book ____I am reading is written by Tomas Hardy.
4.This is the room ____ Shakespeare was born in.
5.The desk ____ leg is broken is very old.
6.I will never forget the day ____ I met the famous astronaut.
7.Everyone wants to visit the place ____ Premier Zhou once worked.
8.We don’t know the reason ____they didn’t keep their promise.
分析:
1.This is the detective who/that came from London.
先行词是人,关系词代表先行词在从句中作主语,填入who或that。
2.The lady whom/that they wanted to visit is a scientist.
先行词是人,关系词代表先行词在从句中作宾语,填入whom或that。
3.The book which/that I am reading is written by Tomas Hardy.
先行词是物,关系词代表先行词在从句中作宾语,填入which或that。
4.This is the room that/which Shakespeare was born in.
先行词是物,关系词代表先行词在从句中作介词in的宾语,in没有提前,填入that或which。
5.The desk whose leg is broken is very old.
关系词代表先行词在从句中作定语,填whose,相当于“桌子的(腿)”。
6.I will never forget the day when I met the famous astronaut.
先行词是时间,关系词代表the day在从句中作时间状语,即“在这一天”,填when。
7.Everyone wants to visit the place where Premier Zhou once worked.
先行词是地点,关系词代表the place在从句中作地点状语,即“在这个地方”,填where。
8.We don’t know the reason why they didn’t keep their promise.
先行词是reason,关系词代表the reason在从句中作原因状语,即“因为这个原因(for the reason”,填why。
重点提示:
1. 选择关系词的关键是看它代替先行词在定语从句中所做的成分,切忌只看先行词,相同的先行词可能需要不同的关系词连接从句。如:
1. I’ll never forget the days ________ we studied in the university.
2. I’ll never forget the days ________ we spent together in the university.
分析:句1填when,因为days在定语从句中作状语,即“在那些日子里,我们在大学学习”;句2填that或which,也可以省略,因为days是spent的宾语,即“spent the days together in the university(一起在大学度过那些日子)”。
2. 近几年的高考题中,定语从句表示时间或地点的先行词经常考查一些较陌生的词,如:
1)先行词 situation(情况,位置), point (要点,地点), case (实例、情况)在定语从
句中作状语时,应该where来引导;
2)先行词occasion(时刻),period(时期,课时), festival(节日)等在定语从句中作时间状语时,用when来引导。
 We’re just trying to reach a point where both sides will sit down together and talk.
 我们尽力达到双方都能够坐下来谈话的程度。(where表示“在这个要点上”)
 I can think of many cases where students obviously knew a lot of English words but couldn’t write a good essay. (where表示“在这些案例中”)
