初中英语知识点总结:定语从句-凯发k8网页登录

  要学定语从句,得知道什么是定语。定语是用来限定、修饰名词或代词的。例如,a good book, good就是定语。那么复合句中修饰名词或代词的从句就叫做定语从句。定语从句由关系代词或关系副词引导,相当于形容词,在句中作定语。被定语从句修饰的词叫先行词,定语从句一般放在先行词的后面。引导定语从句的关联词称为关系词,关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose等,绝对没有what;关系副词有where, when, why, how等。关系词放在先行词和定语从句之间,起连接作用,同时又作定语从句的某个成分。

  一、关系代词引导的定语从句

  1、由who, whom, that, whose引导的从句

  这些词代替的先行词是人的名词或代词,who作主语指人,whom作宾语指人,that既可作主语又可作宾语(作宾语可以省略),可以指人也可以指物。whose 用来指人或物,只用作定语。

  (1)is he the man who/that wants to see you? 他是那个想见你的男人吗?(who/that在从句中作主语)

  (2)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)

  (3)the man whom you spoke to just now is our english teacher 你刚刚说话的那个男人是我们的英语老师

  (4)he man whose son is a doctor is our professor. 那个儿子是医生的男人是我们的教授。

  2、由which, that引导的从句

  它们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,作宾语时可以省略,例如:

  (1)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在从句中作主语)

  (2)the package (which / that)you are carrying is about to come unwrapped. 你拿那个包裹快要散开了。(which / that在从句中作宾语)

  注意:代表物时多用which,但在下列情况中用that而不用which:

  a)先行词是anything, everything, nothing, none等不定代词时;

  b)先行词由every, any, all, some, no, little, few, much等修饰时,这时的that常被省略;

  c)先行词前有序数词或被形容词最高级修饰时;

  d)先行词中既有人又有物时;

  e)整个句中前面已有which,who,that时;

  f)当先行词为物并作表语时;

  g)先行词为one时;

  h)先行词同时又被the only, the very ,the same修饰时;

  二、关系副词引导的定语从句

  1、when指时间在定语从句中做时间状语也可做连接词用   i still remember the day when i first came to the school.

  2、where指地点在定语从句中做地点状语    shanghai is the city where i was born.

  3、why指原因在定语从句中做原因状语 ,用在reason 后面。 please tell me the reason why you missed the plane.

  常见考法

  对于定语从句的考查,多以单选的形式考查学生灵活运用的能力。一般情况下,常从关系词的意义和功能的角度考查,重点是that,which,who引导的定语从句。

  典型例题:you're the only person ______i've ever met ______could do it.

  a. who b. whom c. whom d. who

  解析:先行词person后有两个定语从句,第一个从句省略了关系代词whom.因为, whom作从句中met的宾语,可以省略。第二个从句who could do it.who在从句中作主语,不可省略。

  答案:d

  误区提醒

  当表示时间或地点的名词作先行词时,要判断出它们在从句中作状语还是主语或宾语。作状语时用关系副词,反之用关系代词。

  典型例题:i can never forget the day _______ we worked together and the day ______ we spent together.

  a. when, which b. which, when c. what, that d. on which, when

  解析:两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句。

  答案:a
