题目内容
I __________the poor rabbit, but I didn’t have the right drugs with me at that moment.
A.could save B.had saved C.could have saved D.saved
C
【解析】
试题分析:句意,我本可以救那只可怜的兔子,但是在那个时候,我没有带合适的药。could have done 表示过去本来可以做的事没做,故选C。
考点:情态动词的用法
点评:情态动词有具体的词义,但也同助动词一样,需要与其他词语一起构成句子的谓语,另外情态动词没有人称和数的变化,情态动词后必须跟动词原形。
