hundred，thousand

（1）与具体数字连用时，习惯上用单数，而且也不后接介词of。

He was prepared to pay two million. 他愿意支付200万。

More than a hundred people were injured. 有一百多人受了伤。

（2） 表示不确定的泛指数时，则要用复数，而且要后接介词of，然后才能接名词。如：

The sun was shining. Thousands of people were lying on the beach. 阳光灿烂，数以千计的人躺在海滩上。

there is/are 表示客观存在

have/has 表示主观拥有

1.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 。

2.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.

3.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？
