that 引导主语从句的例句

Answer 1

由that引导主语从句不能省略。请看例句：
That
he
has
told
lies
is
quite
clear.
他说了谎，这一点很明显。
“That
he
has
told
lies”是主语从句，在句中作主语，看作单数，谓语动词用单数。如果省去that，句子就成为：He
has
told
lies
is
quite
clear.句中便有了两个谓语，has
told和is，这样就会引起理解上的混乱，显然是错句。
另外，由that引导的主语从句，往往被放在句尾，前面则用it充当形式主语。如：
It
goes
without
saying
that
he
loves
her
at
the
first
sight.
毫无疑问他对她一见钟情。
It
is
sheer
luck
that
he
survived
the
accident.
他在事故中逃过一劫纯粹是运气。

Answer 2

主语从句，即在复合句中充当主语成分的句子。
that
he
finished
writing
the
composition
in
such
a
short
time
surprised
us.
他在很短的时间内写完作文让我们很惊讶。
主语：he
finished
writing
the
composition
in
such
a
short
time
谓语：surprised
宾语：us
