we should not spend our money testing so many people,most of _are healthy (whom) 求赐教!

whom就是代替前面的people
most of whom 就跟most of them 一样so many people 它还原到句中做什么成分？ 如果做宾语后面的are healthy 是什么成分这句话可以看成是两个句子。至于为什么中间用的是逗号，是因为那里用了most of "whom"将两句连在一起，则不需要用句号。就好像用连词一样的效果。所以，句子 ：most of whom are healthy主语是most of whom谓语是arehealthy 是表语。那这个so many people 还原到从句中就是most of 后面的成分 对吧？ 那它做什么成分哪 ？ 如果它是宾语 那么后面的healthy也是宾语说不通了呀whom 就是代指前面的 so many people.所以还原就应该是most of the people至于成分就好像好刚才说的整个most of the people 做主语做主语应该用who而不是whom天啊~因为前面有most of ，所以后面不可以用who,要用宾格whom如果没有most of,就可以直接这样：we should not spend our money testing so many people,who are healthy .这里就是who当主语而有most of！！就most of whom整个做主语
