2017届高三英语语法知识定语从句复习教案

18. 定语从句
 定语从句在句中做定语,修饰一个名词或代词,被修饰的名词词组或代词即先行词。定语从句通常
出现在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词有:who, whom, whose, that, which等。
关系副词有:when, where, why等。
18.1 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.
农村出现了前所未有的繁荣。(which / that在句中作宾语)
  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)
18.2 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. 任何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+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。
18.3 判断关系代词与关系副词
  方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如:
  this is the mountain village where i stayed last year. 这是我去年呆过的山村。
  i\'ll never forget the days when i worked together with you.我永远不会忘记与你共事的日子。
  判断改错:
  (错) this is the mountain village where i visited last year.
