mind为动词 根据人称否定的话前面用 don't 或doesn't
不存在would you don't mind这种疑问句型
例子：Would you mind to give me a book?回答：No,I don't mind.
would you mind 是一般疑问句的句型,类似于do you mind,can you mind,一般疑问句加否定你应该知道吧,只要加一个not,wouldn't you mind,don't you mind,can't you mind 这样,如果扩展的话Would you mind to give me a book?这样也只是加一个not,Wouldn't you mind to give me a book?这样表达出来的意思依旧是你是否介意给本书给我,无论加不加not,因为其本身就是疑问句.
