關(guān)于must的反意疑問句
She must have been there for a long time,____ ____ 某上面有這樣的說法：陳述部分有must have且沒有具體的過去時(shí)間狀語的疑問句,疑問部分可以用haven't 主語?或didn't 主語.eg)：You must have studied English for three years,haven't you?/ didn't you?你一定讀過三年英語,如果強(qiáng)調(diào)動(dòng)作的完成（一般沒有明確的過去時(shí)間狀語）,一般用haven't 主語,但有時(shí)不是強(qiáng)調(diào)動(dòng)作完成,是表示對(duì)過去肯定的猜測(cè),此時(shí)就可以用didn't 主語.如You must have enjoyed yourself,didn't you?你一定玩的很開心,此時(shí)不表示動(dòng)作完成,故可以用didn't you?就此題來講是用haven't she還是hasn't she?（當(dāng)然用didn't she也是可以的吧.）
