Where are the black pants?为什么用"are

第一个 是pants 所以用复数
而第二个它的中心词是 this pair 是单数所以用单数

where are:pants是主语,问pants在哪,并且pants就是用复数形式
whose is:whose是主语,问pants是谁的,this pair of pants是一条裤子,有一了所以用is。

pants 裤子, 短裤
它的用法和trousers(裤子), glasses(眼镜)等相同,常常用复数,所以是"are".

pants复数啊

where are:pants是主语,问pants在哪
whose is:whose是主语,问pants是谁的
