题目内容
14.We can see only one of the doors ______.( )| A. | are opened | B. | is closed | C. | closes | D. | are closed |
分析 我们只能看见一扇门关着.
解答 答案:B.
根据We can see only one of the doors,可知我们只能看见一扇门关着.门是被关的对象,故用被动语态.从句谓语与one保持一致,用单数.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.由数词加of短语作主语的句子中,谓语动词与前面数词保持一致.
