There be 句型
一、There be ...句型表示的是“某处有(存在) 某人或某物”。
1. 肯定句结构：There be (is，are)+名词+ 地点状语

3. 一般疑问句结构：Is/ Are + 主语 +…
肯定回答：Yes, there is/are.
否定回答：No, there isn’t/aren’t.
二、There be 句型中的主谓一致原则
There be句型中be动词的形式要和其后面的主语在人称和数上保持一致。
(1) 如果句子的主语是单数可数名词或是不可数名词, be动词用“is”。
(2) 如果句子的主语是复数名词，be动词用“are”。
(3) 如果有两个或两个以上的名词作主语，be动词要和最靠近它的那个主语在数上保持一致，也就是我们常说的 “就近原则”。
三、There be结构与have的区别
There be结构表示“客观存在”；have表示“主观所有”。
注意： There have . . . . . . (表达错误，二者不连用）
用there be或 have的适当形式填空。
