Question

i don't think he put his heart into his study ,______? A.does he B. didn't he C.did he D. doesn't

Answer 1

原题应该是这样：I don't think he puts his heart into his study ,______? A.does he B. didn't he C.did he D. doesn't he
答案是A
在解答反意疑问句铅亏时，当主句是I think/suppose/consider/believe/...等时，从句才是表达主要思想的部分，这时附加的问句要针对宾语从句来提问粗激轿。BC两项时态不对；不选D的原因是题目岩肆已经是否定的形式了（否定给转移到前面去），后面的附加问句要用肯定形式。

Answer 2

选B

Answer 3

C

请问为什么选择C啊?能给我详细的解释吗？谢谢！

首先整个句子是否定句,因此前否后肯,用肯定式的疑问句;
其次,宾语从句的主句部分的主语若是第一人称,并表示第一人称的想法,则后面疑问句部分的主语要与从句部分的主语保持一致
