有一道英语选择题有困难,求帮忙
Acollege 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: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.
