有一道英语选择题有困难,求帮忙
A college student and his roommate ____ for three days last december by two men.
A.were kidnapped and held
B.had been kidnapped and held
C.have been kidnapped and held
D.were kidnapped and had been held

答案

答案：A
1.kidnapped和held在这里属于延续动词,所以后面可使用for 3 days这样的时间段,没有必要在使用完成时,哪怕过去完成时.
2.老外说话也喜欢简单,但简单不是不太遵守语法规则,这样简洁些.
