Question

There being nothing else to do,we went home.

句中的be+ing是表示正在进行吗 ? 它在句中是什么词性 ?

Answer 1

有的。
there is no point in doing sth 中文：做某事没有意义。
其中in可以省略不写。
相同意思和用法的句型还有：
There is no use(in) doing sth
There is no sense (in) doing sth
英语中there be的非谓语结构部分用法如下：
There be 结构的非谓语动词形式是there to be 和there being 两种形式。在句中作主语、宾语和状语。
1. there being 结构起名词的作用,直接位于句首作主语,通常用it 作形式主语,并且用for引导。
There being a bus stop near my house is a great advantage.我家旁边有个公共汽车站,很是方便。
It is impossible for there to be any more.
不可能再有了。
2. there be 结构作宾语时,通常用there to be ,常作这样一些词的宾语:expect,like, mean, intend, want,prefer,hate等。
I expect there to be no argument about this.
我期望关于这件事不要再争吵了。
I should prefer there to be no discussion of my private affairs.
我宁愿不要讨论我的私事。
People don't want there to be another war.
人们不希望再有战争了。
另外,作介词宾语时,如果是介词for,只能用"there to be"其它介词用"there being"
The teacher was waiting for there to be complete silence.
老师在等着大家都安静下来。
I never dreamed of there being any good chance for me.
我做梦也没想到我会有好机会。
3. 作状语的there be 形式,通常用"there being"结构。
There being nothing else to do ,we went home.
因为没有其他事可做,我们就回家了。
They closed the door ,there being no customers.
因为没有顾客,他们的店关门了。

Answer 2

后面一句也应该用逗号,因为用了so连接.
There
was
nothing
else
to
do,
so
we
went
home.
前面一句则不需要在逗号后面加连接的词.

Answer 3

不是逗号不逗号的原因，这道题考察的是非谓语短语做主语的问题
