问题
选择题
We are glad to hear that the terrorists ________ by the brave policemen several days ago.
A.are caught
B.were caught
C.have been caught
D.are going to be caught
答案
答案:B
题目分析:句意:我们很高兴的听说几天前恐怖分子被英勇的警察抓住了。根据句意和句中的several days ago可知,这里应该用一般过去时态,并且从句中的主语the terrorists和动词catch之间构成被动的关系,应该用被动语态。故选B。A是一般现在时的被动语态;C是现在完成时的被动语态;D是现在进行时的被动语态。
