there be 句型 肯定句 否定句 回答

there be 句型有时态之分，下面以常见的现在时为例。
There is a football behind the door .
There isn't a football behind the door .
Is there a football behind the door .
Yes , there is ./ No , there isn't .
因为该句型有be动词 ，因此否定和疑问都由be来完成。

THERE BE(IS, ARE, WAS, WERE,WILL BE).
否定：BE动词后加not.如（THERE IS NOT)
回答：肯定，YES, THERE BE.
否定，NO, THERE NOT BE.本回答被网友采纳
