请问这个定语从句中的谓语在哪里
The professor can hardly find sufficient grounds on which to base his argument in favor of the new theory.在这个句子里面有个定语从句,on which to base his argument in favor of the new theory.在这个定语从句中,to base 是接在哪里,这个定语从句中没有谓语?to base 是什么结构?

严格地说,on which to base...这是个不定式短语,所以其中没有主语和谓语.但是这个不定式短语是相当于定语从句来用的.
4）“whword＋不定式”结构不定式前加一个疑问代词（what,which,who,whom,whose）或疑问副词（where,when,how,why）,以及连词whether构成特殊的不定式短语,其作用相当于一个从句,这样的不定式短语常在某些动词后面作宾语.
常见的可以接这种不定式短语的动词有：
know,see,decide,tell,ask,consider,discover,explain,findout,forget,guess,hear,imagine,inquire,learn,observe,perceive,remember,think,understand,wonder等.
【例如】
i couldn’t decide which book to choose.
i can tell you where to get this book.
they found it hard to decide whether to go swimming next sunday or to visit aunt sally in new year.“whword+不定式”结构除了作宾语外,还可以在句中作主语或者表语.
