the doctor and writer ____ in beijing last month A.is B.are C.was D.were

the doctor and writer ____ in beijing last month A.is B.are C.was D.were
答案:C
last month 上个月,用一般过去时,所以在 C,D 中选
而 the doctor and writer 指的是一个人"那位医生兼作家”,所以是单数概念用was
不明白的再问,多谢!

D答案 主语是两个人,谓语动词用复数are,last month是上个月,表过去时,所以are要变为were

C
首先他是过去式,由last month 可以看出
在者the doctor and writer 是同一个人
如果是the doctor and the writer 说明是两个人

C,首先要搞清楚时态,用一般过去时。其次,the doctor and writer是指一个人,是说这个人既是医生也是作家,应该用单数
