He used to be a shy boy.反意疑问句怎么变,两种
He used to be a shy boy,didn't he?
He used to be a shy boy.usedn't he?
都可以.
第一种：used如果看作动词的话,那么需要用助动词did来引起疑问句.
第二种：直接把used看作系动词,那么直接就可以usedn't来变反意疑问句.

usedn't he?
didn't he?

He used to be a shy boy,didn't he?
He used to be a shy boy.usedn't he?
楼上的错了，是反意疑问句，不是否定疑问句

陈述部分的谓语是used to 时，疑问部分用didn't +主语或 usedn't +主语
Didn't he used to be a shy boy
Usedn't he to be a shy boy

He used to be a shy boy,didn't he?
He used to be a shy boy.usedn't he?
但是现在用didnt的更多
