試題分析:考查反意問(wèn)句:對(duì)已發(fā)生的過(guò)去情況的推測(cè),若陳述句謂語(yǔ)部分有“must have done”,而且有表示過(guò)去的時(shí)間狀語(yǔ),問(wèn)句部分用didn't;若沒(méi)有表示過(guò)去的時(shí)間狀語(yǔ),問(wèn)句部分用haven't或hasn't。這句話(huà)的what he complained about,說(shuō)明是過(guò)去的情況。選D。
點(diǎn)評(píng):反意問(wèn)句遵循前否后肯,前肯后否的原則,對(duì)于情態(tài)動(dòng)詞的用法,要根據(jù)具體情況來(lái)定,must表示必須,反意問(wèn)句用must來(lái)做,must be表示推測(cè),和be動(dòng)詞一致。
