how many引导的是特殊疑问句不是一般疑问句。对数量进行提问。
how many +可数名词，how much+不可数名词引导特殊疑问句。例如：1）there are 60 students in our class.转化为How many students are there in our class? 2)There is much drinking water in the bottle.转化为How much water in the bottle?
注意：how many students are there in the class?回答用None.不用No one/Nobody.
