反義疑問句：
（1）當(dāng)主句的主語為第二、三人稱時(shí),其后的簡短問句則應(yīng)與主句相一致（此時(shí),否定只看主句,與從句無關(guān)...）.例如：
Your sister supposes she needs no help, doesn't she? 　　
You thought they could have completed the project, didn't you? 　　
They don't believe she's an engineer, do they? 　　
She doesn't expect that we are coming so soon, does she? 　
(2)但如果主句的時(shí)態(tài)是過去時(shí)等等,疑問句應(yīng)和主句的人稱時(shí)態(tài)保持一致.
had better或have
　　陳述部分有had better,或其中的have表示完成時(shí)態(tài)時(shí),疑問句應(yīng)用hadn’t等開頭： 　　You’d better get up early, hadn’t you? 　　其他情況句中有have時(shí)疑問句應(yīng)用don't等開頭 　　如have表示“有”的時(shí)候,有兩種形式：（have 表示有 可用do或 have來改寫） 　　-He has two sisters,doesn'the? =He has two sisters,hasn't he? 　　-He doesn't have any sisters,doeshe?
很顯然這道題符合第一種情況 肯定是對(duì)Elena提問 而不是對(duì)I提問 而且吸血鬼日記女主角名字也是Elena （全寫Elena Gilbert ）所以肯定是C doesn't she啊
望采納……
