One of the rooms ____ three doors.

题目

One of the rooms ____ three doors.
A.there are B.there is C.have D.if
E has
选什么?说出具体选的理由,如果选E房间是物怎么用表示人所有的has.

答案

ABD显然不对.如果要用there be 句型此句应为In One of the rooms there are three doors.或There are three doors in oneof the rooms.
而此句跟条件句完全搭不上边,所以不选if.
主语为单数,所以选E
