there be sb⼀sth 后什么时候加to do 尀doing 尀过去分词

there be +名词+ doing 或 there be + 名词+ done 及 there be +名词+ to do 这三个句型都是there be 句型，there be 当“有”讲，确是倒装句。句中的名词是主语，所以谓语动词be与其后的名词在人称和数上保持一致（即英语的主谓一致原则），而 doing ,done 还有to do 在there be 句型中都是定语，修饰其前面的名词。
所以呀，there be 后不可能直接加doing , 只能是加了名词后，才可能根据语义需要加出doing,done或者to do 结构。
请采纳！

你好,在这个句子中的to do \doing 是作定语的,.
表示动作要发生在将来时要用to do,
如果动作是正在发生时,要用doing,
如果动作是表示被动的,要用过去分词
如下面的句子:
There is a lot of work to do this night.
Look , there are some people working there.
There is something to drink.
There are some ducks swimming in the river.
There are many bikes repaired.
There are many trees cut down.
