问题补充:
“Never for a second,” the boy told the reporter, “ that my father would come to my rescue.”
A. I doubted
B. do I doubt
C. I have doubted
D. did I doubt
答案:
A. I doubted
B. do I doubt
C. I have doubted
(答案→)D. did I doubt
解析:句意:这个男孩告诉记者:“我从没有一秒钟怀疑爸爸回来救我”。Never for a second是否定意义的词,放在句首的时候,句子用部分倒装,助动词放在主语前面,可以排除AC,因为从句用了would,所以主语应该是一般过去式,所以选D。
