"HOW MANY"和"HOW MACH"有何区别?

应该是how much而不是mach
一个是用在可数名词（how many)
一个是用在不可数名词(how much)
e.g.How many apples do you have?
How much time do we have?

how many 用于可数 比如how many pens do you have?你有多少支钢笔? how much 是问价格的.比如 this pen is very nice,how much?

龙小猫不要误导别人，how much单用通常是问价格，但后接不可数名词时就不是。

HOW MANY 后是接可数名词，HOW MACH 后是接不可数名词的~~

How many mobile phones do you have?
可数
How much water is left in the bottle？ 不可数
