试题答案

B

解析:

主要测试动词时态与语态。考生易误选A项，认为题目中的and为一个并列连词，与其前面的时态应该一致。由题目中的标志性时间状语now可知，横线处应用进行时态，又由于动词question与主语a man之间为动宾关系，故选项B为本题的正确答案。注意，并列连词and前后要求接相同的结构，如：?My cousin went to Canada two years ago. He worked there for a few months and then went to America.?我堂兄两年前去了加拿大。他在那里工作了几个月，然后去了美国。但有时须根据具体的语境来判断（如本题）。?
