解释句型“how much is it?”
“how much is it?” 的意思是“花多少钱”
同意句: How many is it?/How much does it cost?/How many does it cost?
how many用来修饰可数名词的复数，它的句式是:How many+复数名词+一般疑问句＋?
how much用来修饰不可数名词，表示数量，也可单独使用。
e.g. There is a book on the desk. (用how many改为特殊疑问句)
How many books are there on the desk?
How much milk is there in the glass?（玻璃杯里有多少牛奶？）
记忆口诀: how many在句首，名词复数跟着走,一般问句紧相随,其它成分不要丢。
Make a dialogue.

S2: Yes!
S1: What do you want to buy?
