问题补充：
I don think a warm winter always has a negative influence on our life, ?
A. do I
B. does it
C. hasn it
D. don I
答案：
A. do I
(答案→)B. does it
C. hasn it
D. don I
解析：考查反义疑问句。本题的主句是一个否定前移句，原来的语序为：I think a warm winter always doesn’t have a negative influence on our life，句中的I think是一个插入语。使用句子就变成了a warm winter always doesn’t have a negative influence on our life，对其进行反义疑问，故B项正确。
