one在句中作代词代替上文出现的hoverboard
one作代词时可以代替上文中出现的人或物,复数形式是ones,代替上文中出现
的一些人或物。如:
This hoverboard is bigger than that one.
这个飞翔器要比那个大。(one=hoverboard)
I want some pencils. 我想买些铅笔。
Which ones do you want? 你想买些什么样的?
I want the red ones. 我想买些红色的。(ones=pencils)
辨析:one与it
两者都可以代替上文提到过的东西。但二者用法有所不同,one表示泛指,指前面提到过的那类人或事物中的任意一个;it则表示特指,指代前面提到过的那个人或物,名词前通常加定冠词the。如:
—Do you have a bike? 你有辆自行车吗?
—Yes,I have an old one. 是的,我有辆旧的。
—Can you see the ball? 你看见那个球了吗?
—Yes,I can see it. 是的,我看见了。
