替代词ones与the ones的用法区别
ones主要用于替代复数名词，表泛指；若需特指，则用the ones。如：
If you haven’t got a big plate, two small ones will do. 如果没有大盘子，两个小盘也行。
We still have shortcomings, and very big ones too. 我们还有缺点，而且是很大的缺点。
Do you know the ones who moved here recently? 你认识最近搬到这儿来的那些人吗?
The top front teeth are the ones which are most at risk from tooth decay. 上门齿是最容易受到腐蚀的牙齿。
