初中英语知识点总结:定语从句

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;
