Question

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

Answer 1

B

试题分析：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。
