there being 与there to be有何区别

there + being形式,称为非限定存在句,可以作主语、宾语、介词补足成分.
1) 作主语
There being a railway station in the town is a great advantage.镇上有个火车站,真方便呀!
“there to be+NP”
作主语时,通常用for作引导词:
For there to be a mistake in a computer's arithmetic is impossible.计算机计算错误是不可能的.
It was seldom for there to be no late comers.新来者很少没有迟到的.
2) 作宾语
The committee anticipated there being less debate in the second discussion.委员会期望在第二次讨论中争议能少一些.
We expect there to be no objections.我们希望不会有人反对.
I'd prefer there to be more cooperation.我希望有更多的合作.
3) 作介词补足成分：介词是for,用there to be形式； 介词不是for,则用there being形式.
What's the chance of there being an election this year?今年进行选举的可能性有多大?
We have no objection to there being a meeting here.在这儿举行会议,我们不反对.
Jill is waiting for there to be a big party.吉尔等着举行一次盛大的晚会.
此外,there + being形式还可以用作状语分句,形成独立主格结构：
There being no further discussion,the chairman stood up and left the meeting-room.没有可讨论的了,主席站了起来,离开了会议室.
There having been no rain,the stream was dry.一直没有下雨,小溪都干涸了.
“there be...”句型的难点在于它的非限定形式,怎样分辨使用there to be 和there being 两个要点是关键：它们在句子中的成分及与句子中其他成分的搭配关系.如非限定形式的第2小点中的例句：anticipate与there being搭配,而expect 和prefer与there to be配伍.
