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。)
