Question

that在哪些从句可以省略

Answer 1

宾语从句中的that可以省略,定语从句中假如引导词that在从句中充当宾语,可以省略.
例如：宾语从句：i
promise
that
i
will
study
hard.这里的that可以省略
定语从句
this
is
the
factory
that
we
visited
yesterday.这里的that可以省略
但是在这句中：this
is
the
factory
that
lies
in
guangzhou.这里的that做主语,不能省略.
以下情况不可省略
1.that引导主语从句、表语从句、同位语从句时不能省略
2.宾语从句不止一个时,不能省略
如；they
complain（that）they
have
to
do
homework
from
morning
till
night,that
it
is
hard
to
study
good,that
they
are
very
tired.是连续的宾语从句时,第一个可省,后面都不行.
3.宾语从句与主语之间有插入语时,不可省
如：the
teacher
said,happy
and
firmly(插入语),that
we
must
do
homework.
4.引导宾语从句是一个主从复合句
如：i
belive
that
if
i
work
harder,i
will
pass
the
exam.

Answer 2

一：由that引导宾语从句中(that在口语或非正式文体中常省略).
如：
He
said
(that)he
would
like
to
see
the
teacher.
他说他喜欢去看望老师.
I
think
you
are
right.
我想你是对的.
什么是宾语从句?
答：宾语从句就是在主从复合句中作宾语,并且本身又是一个句子,故叫宾语从句.
例如：
I
think
(you
are
a
good
student).
我认为你是个好学生.
