<p>问题：【关于baseon的用法TheProfessorcouldhardlyfindsufficientgrounds__hisargumentsinfavorofthenewtheory.A.tobebasedonB.whichtobaseonC.tobaseonDonwhichtobase选哪个,请一定要说明为什么啊!~】<p>答案：↓↓↓<p class="nav-title mt10" style="border-top:1px solid #ccc;padding-top: 10px;">甘文泉的回答：<div class="content-b">网友采纳 选D...which指代ground... 前面的介词on必须有,因为这里相当于用了baseontheground这个短语..在定语从句中当用which指代了ground,ground前面的on还是应该存在.但这时候自然要加在which前面,所以变成了onwhichtobase
