1．限定词的分类

限定词位于各类形容词之首对中心词和数量关系进行限定。按照限定词在句中的位置可分为前位限定词、中位限定词和后位限定词。前位限定词有倍数词(twice, double, etc)、分数词（two-fifths, etc）、all、half、both、such、what等；中位限定词有冠词（ a, an, the）、指示代词（this, that, theses, those, etc.）、形容词性物主代词(my, his, your, etc.)、名词属格(’s)、不定代词（some, any, every, each, neither, either, no, enough, much, etc.）; 后位限定词包括基数词、序数词、next、past、same、many、much、more、most、few、fewer、 fewest、little、less、least、plenty of 、a lot of、own和last等。 修饰名词时，顺序是：前位限定词＋中位限定词＋后位限定词＋形容词＋被修饰词。

例:I gave him all my beautiful stamps.

The girl’s first lovely toy was a teddy bear.

2．几组限定词的辨析

(1) other, another, the other, the others  

other 指另外的人或物；others 泛指别人，可与some 连用；the other 指两个中的另一个，常和one连用；the others 表示其余所有的人或物；another 则泛指另一个。例：　

Some pupils are reading the text loudly, others are doing their homework.　　

Mrs. Clark has two beautiful hats. One is red, the other is blue.　　

This suit doesn’t fit me. Would you please show me another one?

I have three pencils: one is yellow; another is blue; the other is black.

As for as he is concerned, one piece of music is very much like another.

              (2) either, neither 

       1)  either指两者其中任何一个，neither指两者都不，都可以作代词。如：

Either of you can go.你们两人中可去一个。

Neither of you can go. 你们两人都不可一去。

       2)  都可作形容词，只能和单数可数名词搭配。例：

Either way is all right. 两种方法任意一个都行。

Neither answer is correct. 没有一个答案是正确的。

3）作不定代词时，可单独使用，也可后跟of短语。例：

I wrote to John and Henry, but neither has replied.

我给约翰和亨利都写了信，但没有一个人回信。

Neither of them was in good health, but both worked very hard.

他们两人身体都不好，但他们都努力工作。

4）都可作连词，either … or，neither…nor.注意后面的谓语动词形式与最近的主语

保持一致。例：

              Either you or I am a fool.不是你就是我是傻瓜。

Neither you nor he is a student.你和他都不是学生。

       5）可以作副词表示“也不”。例：

She didn’t want to be a doctor, and she didn’t want to be a teacher, either.

(either  用于否定句，放在句尾，表示“也不”)

I shall not go there today, neither should he.

(neither表示“也不”, 放在句首时句子要倒装)

（3）each，every　

1) 作为形容词，只能与单数可数名词搭配。例：

每位学生都可以找到通向成功的道路。

2) each 作为代词，可单独使用，也可后跟of短语。every只能作形容词，不能 单独使用。例：
