语法拓展

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.

【拓展】（1）how much除了可以询问价格以外，还可以询问物品的数量，意为“多少”，后接不可数名词。

（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。

形容词在句中作定语或作表语是形容词最基本的用法。
