3.18 both, either, neither, all, any, none
　　这些词都可用作代词或形容词。其位置都在be 动词之后，行为动词之前或第一个助动词之后。
　1） both （两者都），either（两者中任何一个），neither （两者都不）。以上词使用范围为两个人或物。例如：
　　Neither of the two boys is clever.　两个男孩都不聪明。
　2） both，either
　 both与复数连用，either与单数连用。例如：
　 Both the boys are clever.　 两个男孩都很聪明。
　 Either of the two boys is clever.
　 There are flowers on both sides of the street. 路边长满了野花。
　 There are flowers on either side of the street.
　3） all （所有的，全部的人或物），any （任何一个）， none （都不）。 以上词使用范围为三者以上。例如：
　 All the flowers are gone.　所有的花都谢了。
　 I don't like any of the flowers.　这些花我都不喜欢。
　 I like none of the flowers.　这些花我都不喜欢。
　注意：all与none用法一样。跟单数名词，用单数动词；跟复数名词，用复数动词。例如：
　　　　All of the students are there. 所有的学生都在那。
　　　　All （of） the milk is there.　 所有的牛奶都在那。

3.19 many, much
　 Many，much都意为"许多"， many + 可数名词，much + 不可数名词。例如：
　　 How many people are there at the meeting? 多少人出席了会议。
　　 How much time has we left? 还剩多少时间？
　　 Many of the workers were at the meeting.许多工人在开会。
　　 Much of the time was spent on learning.学习上化了许多时间。

3.20 few, little, a few, a little
（a） few + 可数名词, （a） little + 不可数名词
　a few / a little 为肯定含义，还有一点
　few / little　为否定含义，没有多少了。例如：
　He has a few friends.　　　他有几个朋友。
　He has few friends.　　　 他几乎没有朋友。
　We still have a little time. 我们还有点时间。
　There is little time left. 几乎没剩下什么时间了。
固定搭配：only a few （=few）　 not a few （=many）　 quite a few （=many） many a （=many）。例如：
　　Many books were sold.
Many a book was sold. 卖出了许多书。
典型例题:
　 Although he 's wealthy，he spends___ on clothes.
　 A. little　 B. few　C. a little　 D. a few
　 答案： A. spend所指的是钱，不可数，只能用little或 a little. 本句为although引导的让步状语从句，由句意知后句为否定含义，因此应用little表示几乎不。
