them，they
如：
This pair of shoes is too dirty.Take them away ， please!
句意：这双鞋太脏了。请把它们拿走！take away拿走，收拾起来bring away带走。This pair of shoes需要由代词them替代
承接 a pair of ...，pairs of ...的动词在数上与 pair 一致，而指代它们的代词则一般用复数形式：
This pair of shoes was rather expensive，but I like them. 虽说这双鞋很贵，但我喜欢。
These shoes are nice. I want to buy them.
复数主语和复数谓语动词are确定用复数are
