代詞one的用法很多,且容易誤用,現(xiàn)將其常見的用法歸納如下:
一. one可以代替前面剛提到過的同一類人或物,其復(fù)數(shù)形式為ones.例如:
I haven ' t got a pen. I ' ll have to buy one.(我沒有鋼筆,我必須去買一支。)
I have a new story-book and several old ones.(我有一本新的故事書和幾本舊的故事書。)
二. 如果one不帶任何前置修飾語,而是單獨(dú)使用時,其意義通常是泛指的。例如:
I have no recorder. I want to buy one.(我沒有錄音機(jī),我想買一臺。)
三. 不定冠詞a/an不可直接和one連用,但a/an后面有形容詞時,可以和one連用。例如:
Have you any knives? I need a sharp one.(你有小刀嗎?我需要一把鋒利的。)
Have you any books? I want to have an interesting one.(你有書嗎?我要一本有意思的。)
四. 當(dāng)one(s)代替特指名詞時,它前面總有定冠詞或其他限定詞。例如:

五. one 只能代替可數(shù)名詞,如果所代替的是特指的不可數(shù)名詞,那就不能用“the one”,而應(yīng)該用that.例如:
The study of English is as important as that(=the study)of Chinese.(學(xué)習(xí)英語與學(xué)習(xí)漢語一樣重要。)
