語法拓展
一、How much引導的特殊疑問句
how much引導的特殊疑問句，可以用來詢問商品的價格，意為“多少錢”，其結構為：“How much +be動詞+其他.”。如果詢問的是單個商品，be動詞用is，如果詢問多個商品，be動詞用are。
—How much is the sweater? —It's five dollars.
—How much are these socks? —They're three dollars.
【拓展】（1）how much除了可以詢問價格以外，還可以詢問物品的數量，意為“多少”，后接不可數名詞。
（2）how many“多少”+可數名詞復數
How much milk do you want?
How many books do you need?
二、形容詞的基本用法
形容詞是表示人或事物的性質、特征的一類詞。如big，white，interesting，difficult等。在句中一般作定語和表語。
1.形容詞作定語
定語是修飾、限定某一名詞或代詞的部分。形容詞作定語，一般用在某個名詞或代詞之前，起到修飾、限定該名詞的作用。
I want to buy a green skirt.
2.形容詞作表語
表語是句中放在be動詞及sound等連系動詞后的部分，起到陳述主語性質、特征的作用。形容詞作表語同樣放在句中be動詞及sound等連系動詞之后。
