当have表示“有”时，反意疑问句应怎么用

have无非就两种用法一作实义动词一作助动词，当作实义动词时，即表示“有”时，用do来问。当作助动词时就用have问。
例：1.You have a car,don't you?当作实义动词时，即表示“有”时;
2.You have bought a car,haven't you?当作助动词时.

当HAVE表示有时，反意疑问句用don't you?
当HAVE不表示有时，反意疑问句用haven't you?

Don't you have``````
Haven't you ```````

比如：you have a book, don't you?
