问题描述：
The singer and dancer ___ come to our party.A.have B.has C.is D.are
B 请具体一点
答
B.has
这个歌唱家兼舞蹈家来参加了我们的聚会.
这句是现在完成时.
come行为动词.行为动词除了进行时或被动语态外,前面不能加be动词.排除C、D.
The singer and dancer 是指一个人具有两种身份,是一个人.排除A、D.
怎样判断The singer and dancer 是指一个人还是两个人呢?看and后面有无the或a/an.如果有,则是两个人；如果没有,则是一个人.如：
The singer and the dancer have both come to our party. 这个歌唱家和这个舞蹈家都来参加了我们的聚会.
