Answer 1

B

試題分析：句意：你昨天的考試怎么樣？不是很好。我本可以做得更好的，但是我弄錯(cuò)了寫作的方向。could have don have本可以做，但實(shí)際未做  will have done將已經(jīng)做了某事
must have done肯定已經(jīng)做了某事   may have done可能已經(jīng)做了某事
點(diǎn)評(píng)：情態(tài)動(dòng)詞+完成時(shí)是高考必考語(yǔ)法點(diǎn)。情態(tài)動(dòng)詞無(wú)論是表達(dá)“推測(cè)和可能性”，還是表達(dá)“虛擬”這一概念，只要是對(duì)過(guò)去已經(jīng)發(fā)生的事情進(jìn)行描述，一律用“情態(tài)動(dòng)詞+have done”這一結(jié)構(gòu)；對(duì)現(xiàn)在或?qū)��?lái)的事情進(jìn)行描述，用“情態(tài)動(dòng)詞+動(dòng)詞或系動(dòng)詞原形”。
