不定量表达法：当描述一个名词时，不知道它的数量。
some, any, most, every, all
(1). some, any :表示“一些”；
some 主要用于肯定句，希望得到肯定回答时，也可用在疑问句中。
any 主要用于否定和疑问句中。
I`d been expecting some letters the whole moring, but there weren`t any for me. [expect 等待, [ɪkˈspekt],现在分词]
(2). most 作形容词时表示大部分的，后面接复数名词。
Most people here are from China. [people: person的复数]
(3). every 表示“每一个，所有”，后面接单数名词。
Every one likes the film.
(4). all 表示“所有”，后面接可数名词复数，不可数名词单数。
All the cars are parked in the parking lot.

(5). both 表示“两者都...”，可作形容词，代词，和副词。
either 是两者之一。 neither 是两者都不。
