不一样.否定疑问句就是一般疑问句的一种,只是前面的助动词或be动词是否定的,例如：他不可爱吗?（Isn't he cute?）.而反义疑问句则是有一个陈述句再加一个疑问句.如：He is cute,isn't he?(他很可爱,是吗?)通常反义疑问句如果前面是肯定句,后面就接否定问句,如果前面是否定句,后面接肯定问句.He isn't a teacher,is he?
两者的简略回答有共同之处,就是都要依据事实来回答.
You are never late for school,are you?(你上学从不迟到,是吗?) Yes,I am.(是的,从不.)
You are never late for school,are you?(你上学从不迟到,是吗?) No,I‘m not.(不,有时迟到.)Isn't he cute?Yes,he is.(他不可爱吗?是的,可爱.)No,heisn't.(不,不可爱.)
