解析試題分析：句意:--在我第一次參觀北京時(shí)，我曾經(jīng)迷路了。--哦，是嗎？你可以請(qǐng)我當(dāng)你的向?qū)�。might have done指過(guò)去可以做某事而未做；could do可能做；would have done 過(guò)去將要做某事；would do過(guò)去將要做某事。根據(jù)句意故選A。
考點(diǎn)：考查情態(tài)動(dòng)詞的用法。
點(diǎn)評(píng)：本題難度適中。情態(tài)動(dòng)詞的完成式是高中階段的重難點(diǎn)之一，需要考生熟記它們的用法，在各類考試中經(jīng)常出現(xiàn)，它主要用于表示對(duì)過(guò)去情況進(jìn)行推測(cè)或責(zé)備等。
即學(xué)即練: —I heard the phone ringing in the office next door.
—You ________ it. They haven’t got a phone yet.
A.couldn’t hear             B.couldn’t have heard
C.didn’t hear           D.wouldn’t have heard
解析：B。由句意可知此處是對(duì)過(guò)去的事情表示推測(cè)，那么否定句用“can/could not+完成時(shí)”，故選B。
