主语从句与同位语从句的区别

Question

如题所述

Answer 1

"主语从句，1
句首，疑问句或that+完整句子。2
It+动词+疑问词/that。
引导词：疑问词和that，that不可省略。
同位语从句，不可能在句首，跟主语从句根本不搭边！同位语从句在名词后，解释名词或一个句子。这些
名词有观点类idea,opinion，事实消息类fact,
news,
word,
story，建议类suggestion,
愿望类，hope,
wish。
引导词：疑问词和that，that不可省略。
主语从句一般是一句话在句子中做主语。
同位语从句，一般是that后面加一句话，和前面的一个词呼应，说的是同一件事情。位语从句属于名词性从句，大多由从属连词that引导，常常跟在fact,
idea,
opinion,
news,
hope,
belief等名词后面。同位语从句一般用来解释或说明这些名词的具体含义或内容，在逻辑上表现为同位关系。例如：
They
are
familiar
with
the
opinion
that
all
matter
consists
of
atoms.他们很熟悉这一观点，所有的物质都是由原子构成的。

Answer 2

1.
作主语的从句叫主语从句，也可以用it作形式主语，把真正的主语放在后面：
That
he
is
ill
is
true.
=
It
is
true
that
he
is
ill.
2.
同位语用来对前面的名词作进一步解释、说明、补充,
若同位语是一个句子，就叫同位语从句。同位语也有限制性和非选择性两种，逗号是非选择性的标志：
We
Chinese
people
are
brave
and
hardworking.
Mr.
Smith,
our
new
teacher,
is
very
kind
to
us.
We
heard
the
news
that
our
team
had
won．
I
had
no
idea
that
you
were
here.

Answer 3

主语从句是整个主句的主语。它的位置一个是在整个主句之前，一个是在后面用it
做形式主语。如
What
he
said
is
true.(what
he
said是主语从句)
It
is
certain
that
he
will
come.(that
he
will
come是主语从句)
而同位语从句是对一名词或代词的解释说明。它的位置在这一名词或代词之后，有的也被很短的谓语动词隔开。如
The
news
that
he
will
come
is
true.(that
he
will
come是同位语从句）
Word
came
that
we
will
have
an
examination.(that
we
will
have
an
examination是同位语从句)

Answer 4

主语从句：
引导词有"what,whatever,who,whom,whose,which,what,whether,how,why"等
eg:1、What
she
knows
is
very
limited
2、when
we
will
have
our
sports
meet
is
still
a
question.
注意：全句如果是被动结构或者一般疑问句，常用形式it引出。
eg:
If
is
said
that
he
is
got
married.
同位语从句：
同位语从句仅仅出现在："beliefe,conclusion,doubt,fact,hope,idea,message,news,notion,proof,rumor,sign,suggestion,theory,thought"等抽象名词后面，用于进一步说明或解释该名词的内容，由that引出
eg:Have
you
heard
the
news
that
he
will
be
promoted.
