2．There be结构的非谓语形式有两个，一个是不定式的复合结构there to be；另一个是动名词的复合结构和独立主格结构there being
(1)．在介词for之后，常跟there to be,在其他介词后，则常跟there being。
E.g. He was not satisfied with there being so little captial（资金） to use.
(2)．there to be和there being都可以做某些动词的宾语，其区别在于：一般用不定式做宾语的动词多与there to be搭配；一般用V－ing做宾语的动词则用there being。
E.g. Would you like there to be a meeting to discuss the problem?
Can you imagine there being much difficulty in living in desert?
(3)．there to be和there being都可做主语，但there to be之前要与for搭配，这种情况多见于it做形式主语的结构中。
E.g. It’s too early for there to be anyone around here.
It is impossible for there to be any more.
There being so good a teacher to guide you in every way is really a good advantage.
(4)．在句首做状语表示原因、条件时，用there being。若动作发生在谓语动词之前，则使用其完成式there having been。
E.g. There being so much to do, he had to stay up.
There having been no buses, we had to walk home.
There being nothing else to do, we went home.
3．There be中间可以加入一些词，如be certain to, be sure, appear to, seem to, used to, have to等等
e.g. There used to be a cinema here before the war.
There doesn’t seem to have been any difficulty over the money question.
There appeared to be a war between his heart and his head.
There had to be a safe way.
There is sure to be a restaurant nearby.
There is thought to be an important change in their interview.
