How much和How many的用法我弄不清how much和how many的用法,比如We need three bottles of milk若对画线部分提问,只画bottles用how much还是how many?若画three bottles of milk用how much还是how many?

We need three bottles of milk
应该是只划three 吧?
这是How many bottles of milk do you need?
如果划上three bottles of的话,
How much milk do you need?
如果three bottles of milk全部.
What do you need?
How many用於对可数名词提问,bottles是可数,所以```
how much用於对不可数名词,milk是不可数`所以```

how much 修饰不可数名词，how many修饰可数名词，这个用how many

how much与how many的区别在于：how many 后接可数名词复数形式,而how much 后接不可数名词.例如：－How many people are there in your family?你家有几口人?－There are five.五口人.－How many birds can you see...

how much用于不可数名词，how many用于可数名词
bottles是可数名词，用how many，three bottles of milk的核心是milk，不可数名词，用how much
