some of the English books belong to me and some are ()

问题描述:

some of the English books belong to me and some are ()
是填yours and theirs还是这两个词的其他形式 说明理由

some of the English books belong to me and some are (you and them)
这句话明显属于省略句,省略了宾语.补充完整应为:
some of the English books belong to me and some of the English books belong to you and them.
为避免累赘,所以原话中用谓语are代替belong to而直接+宾语you和them完成.
