2．幾組限定詞的辨析

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

other 指另外的人或物；others 泛指別人，可與some 連用；the other 指兩個(gè)中的另一個(gè)，常和one連用；the others 表示其余所有的人或物；another 則泛指另一個(gè)。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指兩者其中任何一個(gè)，neither指兩者都不，都可以作代詞。如：

Either of you can go.你們兩人中可去一個(gè)。

Neither of you can go. 你們兩人都不可一去。

       2)  都可作形容詞，只能和單數(shù)可數(shù)名詞搭配。例：

Either way is all right. 兩種方法任意一個(gè)都行。

Neither answer is correct. 沒有一個(gè)答案是正確的。

3）作不定代詞時(shí)，可單獨(dú)使用，也可后跟of短語。例：

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

他們兩人身體都不好，但他們都努力工作。

4）都可作連詞，either … or，neither…nor.注意后面的謂語動(dòng)詞形式與最近的主語

保持一致。例：

Neither you nor he is a student.你和他都不是學(xué)生。

       5）可以作副詞表示“也不”。例：

(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”, 放在句首時(shí)句子要倒裝)

（3）each，every　

1) 作為形容詞，只能與單數(shù)可數(shù)名詞搭配。例：
