在比较结构中,为了避免重复,常用替代词替代名词词组或它的中心词。可以这样用的替代词常用的且较难掌握的有one, ones,that和those。I.替代词one和ones的用法:
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 p
