語(yǔ)法拓展
一、How much引導(dǎo)的特殊疑問(wèn)句
how much引導(dǎo)的特殊疑問(wèn)句，可以用來(lái)詢問(wèn)商品的價(jià)格，意為“多少錢(qián)”，其結(jié)構(gòu)為：“How much +be動(dòng)詞+其他.”。如果詢問(wèn)的是單個(gè)商品，be動(dòng)詞用is，如果詢問(wèn)多個(gè)商品，be動(dòng)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(wèn)價(jià)格以外，還可以詢問(wèn)物品的數(shù)量，意為“多少”，后接不可數(shù)名詞。
（2）how many“多少”+可數(shù)名詞復(fù)數(shù)
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(zhì)、特征的一類詞。如big，white，interesting，difficult等。在句中一般作定語(yǔ)和表語(yǔ)。
1.形容詞作定語(yǔ)
定語(yǔ)是修飾、限定某一名詞或代詞的部分。形容詞作定語(yǔ)，一般用在某個(gè)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(yǔ)
表語(yǔ)是句中放在be動(dòng)詞及sound等連系動(dòng)詞后的部分，起到陳述主語(yǔ)性質(zhì)、特征的作用。形容詞作表語(yǔ)同樣放在句中be動(dòng)詞及sound等連系動(dòng)詞之后。
The story sounds interesting.
形容詞在句中作定語(yǔ)或作表語(yǔ)是形容詞最基本的用法。
