我认为楼主问的是
that从句作主语时
也就是充当主语从句时
主语从句是放前面
还是放后面。这和that的用法无关。that引导主语从句
that当然是在从句前
并且不能省。
that从句作主语时经常放在后面
而用it作形式主语。如
that
the
earth
turns
around
the
sun
is
known
to
all.地球绕太阳转这一点是众所周知的
=
it
is
known
to
all
that
the
earth
turns
around
the
sun.
that从句作主语
放在前面
显得头重脚轻
故
经常用it作形式主语
而把真主语that从句置后。
再如:it
is
a
pity
that
he
has
made
such
a
foolish
mistake.
总之
that从句作主语
放前
放后都可以,最好放后
避免头重脚轻。
