Question

【题目】I don't think he did such a stupid thing last night,__________?

A. do I B. could he C. did he D. has he

Answer 1

【答案】C

【解析】

句意：我不认为他昨晚做了这么蠢的事，是吗？考查反义疑问句。反义疑问句构成有两种形式：（1）前肯后否；（2）前否后肯。I don't think+从句，否定从句的内容，这叫否定前移；变为反义疑问句时，后面的问句需用肯定形式；本句宾语从句he did such a stupid thing last night是一般过去时，它的疑问句是did he，故选C。
