You are ……, aren't you?
结构：肯定句，+否定式助动词+主词?
说明：这是一种反意<疑问句>，其结构特点是：第一部分是肯定式，第二部分就用否定式。直述句的<主词>是<名词>时，附加问句的<主词>要用<代名词>代替：it 代替 this， that，<不定词>（当<主词>）或<动名词>（当<主词>）等;they 代替 these，those， people 等。下列<助动词>的否定缩写式较易弄错：will not->won't;would not-> wouldn't;should not->shouldn't;can not->can't;could not->couldn't; might not->mightn't;ought not->oughtn't.直述句有一般<动词>现在式，则附加问句用 do 或 does 代替;有一般<动词>过去式，则附加问句用 did 代替。
