這些不定代詞不僅在含義上有單復(fù)數(shù)之分,而且在用法上有泛指(無the)和特指(有the)之別。其用法區(qū)別可歸納如下:

1. 指單數(shù)時(shí)的用法指單數(shù)時(shí),若泛指用another,若特指用 the other。如:Give me another (one). 另外給我一個(gè)。
Shut the other eye, please. 請(qǐng)把另一只眼睛也閉上。

2. 指復(fù)數(shù)時(shí)的用法指復(fù)數(shù)時(shí),若泛指用 other(后接復(fù)數(shù)名詞),若特指用the other(后接復(fù)數(shù)名詞)。如:There are other ways of doing it. 做這事還有其他的辦法。
Where have the other students gone? 其他學(xué)生都到哪里去了?

3. other的用法others永遠(yuǎn)表示復(fù)數(shù)意義(且其后不能再接名詞)。其用法大致相當(dāng)于)“other+復(fù)數(shù)名詞”,同樣地 the others 大致相當(dāng)于“the other+復(fù)數(shù)名詞”。如:Other people [Others] may not think that way. 別的人可能不這樣想。
He is cleverer than the others [the other students] in his class. 他比班上其他學(xué)生聰明。

4. another的用法another一般只能表單數(shù),且其后接名詞也只能接單數(shù)名詞。但是若其后有數(shù)詞或 few 修飾時(shí),則也可接復(fù)數(shù)名詞。如:We need another few chairs. 我們還需要幾把椅子。
In another two weeks it'll be finished. 再過兩個(gè)星期就可做完了。

5. 與 some連用與 some 對(duì)比使用時(shí),用 others(此時(shí)與 some 同義)。如:Some say yes, and others say no. 有人說對(duì),有人說不對(duì)。
