He never said that he was good at Maths,______? A,was he B,wasn"t he C.did he D.didn"t he

He never said that he was good at Maths,______?
A,was he B,wasn"t he C.did he D.didn"t he
------ 答案； C
----- 主句是 never said ,这是否定 ---- 所以要“肯定反意”了。
----- 不能拿从句来“反意”
---- 懂了吗？

never 是否定的意思，诘问句用相反同时态反诘
said 是过去式，否定过去式的诘问是肯定过去式 did he, 选 C

C. He never said that he was good at Maths, ( did he )?
never said = 否定, 反意疑问便要用 肯定 ( did )

逗号之前的句子：He never said that he was good at Maths.
知识点1: 这句话是 “that+简单句” 构成的宾语从句（即that+he was good at Maths是从句，是整个句子的宾语部分），从属于主句的，所以真正的谓语动词就不是Be动词（即was ）了。真正的谓语动词是在主句中的，即主句He never said ……里的said，所以只能用did/didn't。
知识点2: 反意疑问句，“前肯后否”、“前否后肯”。
主句中的never said是否定的含义，所以满足“前否后肯”。所以是 did he而不是was he.

答案：C did he
解题关键：找对句子真正的谓语。
