不定代词有许多,最不好掌握的是one及其一系列变形,如:oneself(反身代词),ones(复数),one s(所有格)。其用法为:
1) one修饰名词时,强调数量“一个”,a和an只表示单数形式。
【例如】
One dish is not enough. I need at least two.
An apple looks different from a pear.
2) one常用来表示某一个人,有时可以用he或she来代替。
【例如】
One is usually over sensitive about one s own family when he is out.
3) ones是one的复数,前面可以用定冠词和指示代词修饰。oneself为反身
代词,one s为所有格形式。
【例如】
One mustn t take oneself too seriously.
These ones are better than those ones.
