  1.one只能替代单数名词,one的复数形式ones只能替代复数名词。例如:

  My child doesn't like this book.Show her a more interesting one.

  2.替代词one或ones必须带有一个限定或修饰词,它们和所替代的名词中心词所指不一定是同一对象,这是替代词one或ones在用法上的一个重要特征。例如:

  I don't like this book.I'd like a more interesting one.

  3.当替代词one或ones带有后置修饰语时,它们前面总有定冠词。例如:

  Our new cassette is more expensive than the one we had before.

  4.当替代词one或ones在形容词比较级、最高级以及某些限定词如this,that,which和序数词等之后,可以省略。例如:

  This book is much better than that(one).

  5.替代词one或ones通常不用在物主代词和名词所有格之后。如不可说my one(s),your one(s),Peter's one(s)等等。one或ones也不能用在own之后。

  但是,如果有了形容词,one(s)可以和物主代词及名词所有格连用。如:

  My cheap camera seems to be just as good as John's expensive one.

  6.one作替代词时,在of前面不能用the one来表示所属关系和类似概念。如不可说:

  He put down his gun and picked up the one of Henry.

  该用一个所有格来表示He picked up Henry's.

  7.当两个形容词表示对照的意思时,不能使用替代词one。仅在其中一个形容词后加上名词即可。例如:

  Don't praise the younger child in the presence of the elder.

  8.替代词one如果不带任何前置修饰语,即它的前面既没有限定词,又没有形容词时,便不是替代名词词组的中心词,而是替代整个名词词组。这时,one=a+单数名词。例如:

  A cake made of wheat costs less than one made of rice.(one =a cake)

  one的这种用法是泛指同类事物中的任何一个,相当一个不定冠词,因此它没有复数形式。要泛指复数事物,只能用some。例如:

  Here are a few apples.Would you like some(=some of them)?
