一個(gè)獨(dú)立主格 The bus was crowded with passengers going home from market,most of ________
The bus was crowded with passengers going home from market,most of ________ carrying heavy bags and baskets full of fruit and vegetables they had bought there.
A.them B.who C.whom D.which
most of them carrying...為獨(dú)立主格結(jié)構(gòu),相當(dāng)于 and most of them were carrying...,也可改為：most of whom were carrying.
我是想問(wèn) 為什么相當(dāng)于and most of them were carrying..,這個(gè)were carrying 是表示過(guò)去進(jìn)行時(shí)?were 是什么用法 那前面也沒(méi)交代是進(jìn)行時(shí)啊
