where to find him and how to find hem----to us. are not known is not known doesn;t know has not known 选B。怎么解释呢？
where to find him and how to find them_____to us. A.are not known B.is not known C.doesn;t know D.has not known 正确答案:B 译文:我们还不知道能在哪儿怎么样才能找到他们. 解析:考查主谓一致,由两个以上疑问词加不定式作为主语,一般谓语动词用复数形式,如果两个部分表达同一概念,属于同一整体,谓语动词仍然用单数形式.这里"在哪儿/怎么样",我们通常看作是同一概念的两个方面,所以用单数形式,而且事情不为人知,是被知道,所以用被动式.答案选择:B
