There‘re shops on either side of the street,some of them do not close until 12 at night.为社么是填them?那The old man had a son and two daughters,__treated well,which make her sad.这边为什么填none of whom?不是说定语从句不可以用them吗?上一个例子怎么解释呢There‘reshops on either side of the street,some of them do not close until 12 at night.
