【題目】-Where is my suitcase？

-Somebody_______it away by mistake．

A. must have takenB. could take

C. should takeD. must take

【答案】A

【解析】

考查情態(tài)動(dòng)詞+have done。句意：我的手提箱在哪里？一定是有人誤把它拿走了。must have done一定做某事．表示對(duì)過(guò)去事情的較有把握的推測(cè)，這時(shí)只能用在肯定句中，意思是"肯定/必須已經(jīng)干過(guò)…"．could do 能夠做某事，should do 應(yīng)該做某事，must do必須做某事。故A選項(xiàng)正確．
