how many的用法

对数量进行提问，many后面跟可数名词复数。

How many pandas are there?那里有多少只熊猫？

How many lions can you see?你能看到多少只狮子？

对therebe句型中主语的数量如：some，five，onlyone等提问时，如果主语是可数名词，不管主语是单数还是复数一般都用复数形式提问。

因为问话人不知道具体的数量是多少，而且many只能接可数名词复数形式，所以be一定要用are。即用Howmany+可数名词复数＋are there+地点／时间状语的句型结构。例如：

There are seven days in a week. (对划线部分进行提问）How many days are there in a week?翻译：一周有多少天？
