whose后面跟单数还是复数

单数复数都可以

whose之后的名词不加the，而是直接加名词，中文意思是“谁的……” 

例如，这是谁的鞋子?

Whose shoes are these? 

又如:

Whose shirt is this? = Whose is this shirt? 它们是同义句。

whose 后面可以直接跟名词，“whose +名词”构成完整的名词短语，在句子里一起。

whose.还可以用来引导定语从句，whose后面跟的名词，如果是复数，定语从句的谓语动词就用复数，如实单数就用单数。

We live in a house whose windows are broken.

We live in a house whose door is destroyed.
