Question

----Doctors, it seems that you like to work with animals.
----Yes, I think animals should ______ as our friends.

A．regard

B．be regarded

C．be regarding

D．are regarded

Answer 1

B

试题分析：句意：大夫，好像你喜欢和动物们共事？——是的，我认为动物们应该被当做我们的朋友。结合语境可知动物们是动作的对象，故用被动语态，情态动词should后面动词用原形，故选B。
点评：此类题型主要是确定句子主语与谓语动词的关系。如果是主动关系则用主动语态，反之如果是动宾关系，则用被动语态。
