内容提要:


1、 教学目的: 掌握定语从句的结构、分清关系代词及关系副词和如何运用来写作!  
2、重难点突破 :  
I.关系代词引导的定语从句
  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。
1)who, whom, that
   这些词代替的先行词是人的名词或代词,在从句中作主语和宾语。例如:
   Is he the man who/that wants to see you?
他就是你想见的人吗?(who/that在从句中作主语)
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。(whom/that在从句中作宾语)
2) whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换)。例如:
They rushed over to help the man whose car had broken down.那人车坏了,大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green.请递给我那本绿皮的书。
3)which, that所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等。例如:
  A prosperity which / that had never been seen before appears in the countryside.
     农村发生了前所未有的繁荣。(which / that在句中作主语)
The package (which / that)you are carrying is about to come unwrapped.你拿的包快散了。(which / that在句中作宾语)
 
II. 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。
1)关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用。例如:
There are occasions when (on which) one must yield. 人都有不得不屈服的时候。
   Beijing is the place where(in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer?这就是他拒绝我们帮助他的理由吗?
2)that代替关系副词,可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句,在口语中that常被省略。例如:
His father died the year (that / when / in which) he was born.他父亲在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。
