答案選D.didn't
反意疑問句,從last week 可以判斷這里只有D.didn't正確最佳答案是was't嗎當must+have done表示對過去的情況進行推測（一般句中有明確的過去時間狀語），問句要根據(jù)陳述部分謂語的情況用“didn't+主語”或“wasn't/weren't+主語”；如果強調(diào)動作的完成（一般沒有明確的過去時間狀語），問句要用“haven't/hasn't+主語”。 She must have read the novel last week,didn't she? 她上星期一定讀了這本小說，是嗎？ You must have told her about it,haven't you? 你一定把這事告訴她了，是嗎？恕我愚昧，was‘t是最佳的嗎？是的
