宾语从句的否定转移及其反义疑问句?

否定转移
条件：第一人称+ think/suppose/believe/imagine/guess/expect.反义疑问句的助动词看从句.
其他人称看主句.
e.g.I suppose the report will be deleted,wasn’t it?
I don’t think he came back two months ago,did he?
She thinks her husband is the best one in the team,doesn’t she?
值得注意的是,当这些词后接的宾语从句的否定转移到主句时,其仍属否定词,故其后的短语句式应为肯定.
e.g.
I don't believe that he can translate this book,can he?
we don;t imagine the twins have arrives,have they?
