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 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)
