Answer 1

分析 --你去聽(tīng)講座了嗎？
--沒(méi)有．我們本來(lái)能夠去的，但是路上交通太擁擠了．

解答 答案：C．
根據(jù)題干問(wèn)話中謂語(yǔ)動(dòng)詞did可知，聽(tīng)講座此事發(fā)生在過(guò)去；再由答話中but句意可知講座沒(méi)有聽(tīng)成；另"情態(tài)動(dòng)詞+have done"此結(jié)構(gòu)表示對(duì)過(guò)去情況的推測(cè)．C選項(xiàng)could have done表過(guò)去本來(lái)能做成的（卻沒(méi)做成），we could have attended it意為"我們本來(lái)能聽(tīng)成講座的"事實(shí)上沒(méi)有，符合句意，故選C．A選項(xiàng)，must have done表過(guò)去肯定做了某事；B選項(xiàng)，shouldn't have done表過(guò)去本不該做某事而做了；D選項(xiàng)，could do不表對(duì)過(guò)去的推測(cè)．

點(diǎn)評(píng) 此題考查情態(tài)動(dòng)詞對(duì)過(guò)去情況的推測(cè)．其基本結(jié)構(gòu)為"情態(tài)動(dòng)詞+have done"常見(jiàn)的形式有must have done表過(guò)去肯定做了某事；should/ought to have done表本該做某事卻沒(méi)有做；shouldn't/oughtn't to have done表本不該做某事卻做了；could have done表過(guò)去本來(lái)可以做某事卻沒(méi)有做；can't have done表過(guò)去肯定沒(méi)有做某事；needn't have done表本沒(méi)有必要做某事卻做了．
