there be句型和it做形式主语形成的主语从句区别

不可以.否则会改变原意.
"There be"句型是倒装句,原句表示“这里没有…怀疑”
第二句表示“它不是…怀疑”,
There is(was) no 动词ing
结构相当于It is(was) impossible
to 动词原形,如：There is no going home.=It is
impossible to go home.
There is no living with him.=It is
impossible to live with him..
There is no knowing what may
happen.=It is impossible to knowi what may happen
注意:There be 句型的否定句有两
种构成方式,一种是将否定副
词not放在be 之后,如：
There isn’t a box in the room.
房间里没有盒子.There aren’t any pens on the
desk.课桌上没有钢笔.
There hasn’t been any rain
for a week.一周没下雨了.
There won’t be a meeting
today.今天没有会议.另一种是在主语前加上不定代词no ,如：
There is no water in the bottle.
瓶子里没有水.
There are no pictures on the
wall.墙上没有图画.There will be no one at home
tomorrow morning.明天上午不
会有人在家.
There might be no money
left.或许没有剩下什么钱.
还有什么问题?

不可以 It is wonderful that wo have two days off to do our own things . 像这种系表结构的用it刚刚好...

No it isn't
