1、there be结构表示“某时、某地存在着什么事物或人”，包括there is、there are、there was、there were。
2、在there be 句型中，主语是单数，be 动词用is或was；主语是复数，be 动词用are或were；如有几件物品，be 动词根据最近be 动词的那个名词决定——“就近原则”。
3、there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词调到句首。
4、some和any在there be 句型中的运用：some 用于肯定句， any 用于否定句或疑问句。
5、and 和or 在there be句型中的运用：and 用于肯定句， or 用于否定句或疑问句。
6、针对数量提问的特殊疑问句的基本结构是：
How many + 名词复数 + are there + 介词短语？
How much + 不可数名词 + is there + 介词短语？
7、针对主语提问的特殊疑问句的基本结构是： What’s + 介词短语？
