- a little bit , a bit&a little
作状语表示“有点,一点”时,三者可以通用。但a little bit 的程度比后两者稍弱一些。例如:

a bit 加上of可以和a little 一样修饰不可数名词,例如:

(2)short 作“矮的”讲时,可以指人的个子矮,反义词是tall(高的)。例如:
He is a short man. 他是一个身材矮小的人。
- straight
(1)straight 作形容词,意为“直的”,可用来形容头发,也可用来形容其他事物,在句子中可以作定语也可以做表语。例如:

口诀:
every指全体each强调单,each两个以上every三。
every指定each却不限,each同位every它不管。
every复合不接of短,each不与not句中现。
every,not句中若相连,部分否定理解难。
other可与every,each连,含义有别记心间。
- person&people
person 可数名词,有单、复数形式,着重指个人方面,可与不定冠词a或数词连用。例如:
