1.I don't think he could have done such a stupid thing,_______?
A.do I B. could he C.has he D.did he
选C
解释：
本句是个带有宾语从句的复合句,因为主句的主语是第一人称I,谓语动词是think,因此反意疑问句要根据宾语从句的主谓结构来安排反义疑问句；其次,因为主句的谓语动词是否定式,变成反意疑问句时,要把宾语从句看成是否定句,翻译疑问句要用肯定式；再其次,宾语从句的谓语动词是用情态动词来表示对过去所发生的事件的否定的推断,又没有确定的过去时间状语,因此反义疑问句要用：has加主语构成,选项C是唯一正确的答案.
2.He dislikes whatching TV in the evening ,______?
A.doesn't he B. does he
选A
3.He is unable to finish it without any help,______?
A.is he B.isn't he C.arethey D.aren't they
选B
解释：
如果句子中含有由否定的前缀或后缀构成的表示否定意义的动词或形容词,只要谓语动词是肯定式,该句子就要被看成是肯定句,反义疑问部分就要用否定式.
如以上两句中的dislikes/is unable就是这种情况.并不因为它们表示否定的意义就把它们看成是否定句.
