问题描述：
___to his research work,the professor cared little about any other things.
A.Devoted B.Having devoted C.Devoting D.To devote 选哪个?为什么?
答
C
devote to sth.
句中以动名词的形式坐伴随状语，又因为这两个动作同时发生，所以不用having devoted
答
B
是完成时，又是分词作壮语句型，所以是B。
答
选A, devote是一个及物动词,后面一定要跟宾语的,如后面没有宾语,只能用它的系表结构/被动结构be devoted to...,此句中devoted to his research work相当于这样一个原因状语从句：Because he was devoted to his research work,因为它的主语和后面主句主语一致,又是一个被动语态句,所以简化为过去分词短语作状语.
答
A
devote是一个及物动词，devote oneself to sth,这里用被动，所以省略了oneself
状语
教授献身于他的研究事业，所以对别的事情几乎不关心。
