一、概說
英語中的there be結構主要表示某處存在有某物，所以通常被稱為存在句。其中的there為引導詞，無詞義，be為謂語動詞，there be后面的名詞為句子主語。
二、there be結構的謂語形式
1. 主謂一致問題
:若只有一個主語，謂語的數則取決于該主語的數；若有幾個主語并列，則通常是與靠近的主語保持一致：
There is a man at the door. 門口有個人。
There are some girls in the room. 房間里有幾個女孩。
There is a pen and some books on the desk. 桌上有一支鋼筆和一些書。
2. 時態問題
there be結構的時態由其中的謂語動詞be來體現，它可以有一般現在時、一般將來時、一般過去時、現在完成時以及過去完成時等多種時態形式：
There is going to be [will be] an English film tonight. 今晚將有一場英語電影。
There was a lot to be done. 有很多事要做。
There were some children swimming in the river. 有些小孩在河里游泳。
There have been many such accidents. 已發生了好幾起那樣的事故。
There had been two sea fights between them. 他們之間發生了兩場海戰。
3. 與情態動詞連用
there be結構有時可以與情態動詞連用：

There used to be a hospital here. 原來這里有家醫院。
He felt there must be something wrong. 他感到準有什么問題。
There might still be hope. 可能還有希望。
There ought to be a comma here. 這兒應有一個逗號。
4. 動詞be換成其他動詞
有時可將there be中的動詞be 換為 live, remain, seem, appear, exist, stand, lie, come等：
Once upon a time there lived a man known by the name of Joe Beef. 從前有個人名叫喬·比夫。
There seems [appears] something the matter with her. 她好像是出了什么事似的。

5. 與其他動詞搭配使用
there be結構有時可與其他動詞搭配使用，構成一種復合謂語：
There seemed to be nobody about, so I went in. 附近似乎沒有人，因此我就走了進去。
There happened to be a man walking by. 恰好有一個人從旁經過。
三、there be結構的非謂語形式

(2) 用作介詞for的賓語：
