一、How much引导的特殊疑问句
how much引导的特殊疑问句，可以用来询问商品的价格，意为“多少钱”，其结构为：“How much +be动词+其他.”。如果询问的是单个商品，be动词用is，如果询问多个商品，be动词用are。
—How much is the sweater? —It's five dollars.
—How much are these socks? —They're three dollars.

（2）how many“多少”+可数名词复数
How much milk do you want?
How many books do you need?
二、形容词的基本用法
形容词是表示人或事物的性质、特征的一类词。如big，white，interesting，difficult等。在句中一般作定语和表语。
1.形容词作定语
定语是修饰、限定某一名词或代词的部分。形容词作定语，一般用在某个名词或代词之前，起到修饰、限定该名词的作用。
I want to buy a green skirt.
2.形容词作表语
表语是句中放在be动词及sound等连系动词后的部分，起到陈述主语性质、特征的作用。形容词作表语同样放在句中be动词及sound等连系动词之后。
