there been(is/are/was)用於完整的句子,例如:
There is a ball under the chair. 椅子下面有一個球。
而there  been和there being則用於某些動詞之後,there being還可以用於獨立主格結構作狀語。
例如:
I expect there to be a party tomorrow. 我希望明天開派對。
There being no movie ticket left, we went home, disappointed.
There be 做非謂語時,be可以是不定式(to be)或(being),所以非謂語形式有 there being 和 there to be.
2、There 作邏輯主語。非謂語形式的 there to be 和there being 結構可用作主語、賓語、或狀語等。
作獨立主句結構there being是對的,而there been是錯誤的,除非改成there having been。
