在XXXXXXX,isnt中,XXXXXXX部分必须含有 is 且是肯定句。例:She is fine, isn't she? 在XXXXXXXX,doesnt?中,XXXXXXXX部分用一般现在时,含有实意动词第三人称单数且是肯定句l例如:She speaks English well, doesn't she? 其实这是反义疑问句的问题:1)前肯定后否定 2)后面的谓语动词与前面的保持一致
is是系表结构助动词,does是动词。。。XXXXXXXX,isnt用于前句中没有明显动作的时候,比如:她很漂亮,不是吗?She is beautiful ,isnt it?追问
那 the boy has a new MP4, XXXXhe?用什么

It is a lovely day, isn't it? He does his homework every day, doesn't he? 使用isn't的问句,主句的动词为系动词,且为单数主语;使用doesn't 的问句,其主句动词为行为动词,且主语为单数。
