问题描述:

The book must have been translated into English three years ago,_.
A.mustn't it B.didn't it C.wasn't it D.hasn't it
请说明原因

D
must have been(must表示猜测)
have been才是book的真正谓语 反义疑问句是对谓语进行提问 book是单三 反义疑问句就用has 且主句是肯定猜测 所以反义疑问句就得 用否定提问 因此答案是hasn't it

有问题欢迎追问~答案选C 孩子 = =‘sorry 我看错了 three years ago过去时的标志 因此用wasn't反问= = 不好意思
