一．there/here be结构
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。
here be结构与它类似，用法也完全相同，只不过是表示“这里存在着什么事物或人”。
二．和have、has、had的区别：
（1）There be 句型表示：在某地有某物（或人）；而have、has、had表示：某人拥有某物。
（2）在there be 句型中，主语是单数，be 动词用is；主语是复数，be 动词用are；如有几件物品，be 动词根据最近be 动词的那个名词决定即“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）there be句型与have(has) 的区别：there be 表示在某地有某物（或人）；have(has) 表示某人拥有某物。
（5）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。
（6）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。
（7）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？
（8）针对主语提问的特殊疑问句的基本结构是： What’s + 介词短语？
（9）There be结构一般用在句子的开头，而have等词只能用于某一个主语后面。练一练：
