試題分析：考察情態(tài)動(dòng)詞用法。本題考察的是情態(tài)動(dòng)詞對(duì)過(guò)去情況的虛擬。must have done是對(duì)過(guò)去情況的肯定推測(cè)“一定做了某事”；could have done本可以做某事，實(shí)際上卻未做；可能做了某事。句意：不要生我們的氣。我們本可以和你一起吃飯的。但是當(dāng)你打電話的時(shí)候，我們忙于準(zhǔn)備我們的報(bào)告。根據(jù)句意說(shuō)明本句中的could have done本可以做某事，實(shí)際上卻未做；是一個(gè)虛擬語(yǔ)氣。故D正確。
點(diǎn)評(píng)：本題是高考必考考點(diǎn)，一定要牢記句型意思。must have done過(guò)去肯定做了某事。should have done 本應(yīng)該做而實(shí)際未做。can’t have done 過(guò)去不可能做了某事；shouldn’t have done 本不應(yīng)該做而實(shí)際做了。 need have done 本有必要做某事；needn’t have done 本沒(méi)有必要做某事；注意沒(méi)有 mustn’t have done的形式。
