怎么找出定语从句中先行词,然后怎么判断先行词做什么成份。

如题所述

先行词是名词或代词,如果名词或代词后面有修饰它们的句子且它们在句中充当某一成分,它们就是先行词.
把先行词还原到从句中,就能判断做什么成份.
如:I
will
never
forget
the
day
when
I
first
went
to
school.(先行词是day)
从句=I
first
went
to
school
on
the
day.
(on
the
day
在从句中作状语=when)
I
will
never
forget
the
day
that
was
very
special
to
me.(先行词是day)
从句=The
day
was
very
special
to
me
(the
day
在从句中作主语=that/which)

最简单的方法:看从句缺什么成分。
比如:
1.he
is
the
policeman
who
caught
the
thief
the
other
day.
去掉who后,从句缺主语:caught
the
thief
the
other
day.所以who充当主语。
2.he
is
the
policeman
that
i
met
yesterday.
去掉that后,从句缺宾语:i
met
yesterday.所以that充当宾语。
3.i
like
the
book
whose
cover
is
dark
green.
去掉whose后,从句缺定语:(its)
cover
is
dark
green.故whose充当定语。
4.the
temple
where
he
used
to
live
has
been
destroyed.
去掉where后,从句缺状语:he
used
to
live
(in
the
temple).故where充当状语。
如果仅仅是想区分主语或宾语,还有一种简便的方法,就是看关系词后是什么词性的词,后面是名词(主语)的话先行词就是宾语,是动词(谓语)的话先行词就是主语。
如:
1.father
is
talking
to
the
man
that
has
stayed
here
for
a
long
time.
句中that后是谓语动词,所以that就充当主语,可以用who来代替。
2.father
is
talking
to
the
man
that
we
are
afraid
of.
句中that后是名词(主语),所以that就充当宾语,可以用whom来代替。

1、先行词位置:句中的先行词一般出现在定语从句的关系词之前。

2、判断先行词充当何种句子成分的方法:一般来讲,因为定语从句中的关系词就是指代先行词的,所以可以根据关系词充当的句子成分得出先行词所充当的句子成分,例如:

Is he the man who/that wants to see you?他就是想见你的人吗?

本句中的先行词即是the man,而 who/that是关系词,因为who/that在定语从句中做主语成分,所以先行词在定语从句中就是做主语成分。

扩展资料:

定语从句关系词介绍:

关系词常有3个作用:

①连接作用,连接主句和定语从句。

②指代先行词。

③在定语从句中担当成分。

注:关系代词有主语、宾语、定语之分。一般who做主语或其宾格形式的whom做宾语(whom作宾语时可省略),whose作为定语(whose不可省略)。关系代词在从句中作主语,宾语,定语等,关系副词在从句中作地点状语(where),时间状语(when),原因状语(why)。
