Answer 1

同位语从句与定语从句的区别
一,同位语从句相当于一个名词,对前面的名词
起解释说明作用,而定语从句相当于一个形容词,
对前面的名词,代词起修饰限制作用.
The
fact
that
they
won
the
game
pleased
all
of
them.
(that
clause
=
the
fact)
The
news
that
they
told
us
cheered
us
all.
(that
指代
the
news)
Suddenly
the
thought
came
to
me
that
he
could
go
blind.
(同位从句)
The
thought
that
he
could
go
blind
made
me
feel
sad.
(同位从句)
(定从)
The
thought
that
suddenly
came
to
me
is
terrible.
二,名词
idea,
word,
news,
promise,
fact,
information,
problem,
question,
hope,
truth,
suggestion,
doubt,
fear,
belief等后常跟一个同位语从句来说明该名词的内
容,解释其内涵.
1.
He
made
a
promise
that
whoever
could
set
him
free,
he
would
show
him
all
the
treasures
in
the
world.
2.
Word
(News)
came
that
our
team
won
the
game.
3.
Who
will
go
to
find
out
the
information
when
they
will
set
out
to
visit
the
Great
Wall?
三,引导同位语从句的
that,
whether,
when,
where,
who,
how,
why等不等于或不能替换前面的名词或代词,这些引导词在同
位语从句中均不能省略,引导同位语从句的
连接副
词when,
where,
who,
how等在同位
词从句中作状语时,有疑问意义.that无实义不作句子成分(如上述例子);
而定语从句的引导词要在从句中担任句子成分,that,
which,
who/whom等作从句宾
语时常可省略.
1.
I
have
known
the
fact
that
(不等于fact)
our
school
has
gone
far
ahead
of
any
other
school
in
our
country
every
aspect.
2.
He
would
not
tell
us
the
idea
whether
(不等于
idea)
he
was
wiling
to
help
us
out
of
difficulty.
3.
I
could
hardly
believe
the
reason
why
(不可替
换
reason)
he
was
late
again.(why有疑问意义)
