試題分析：句意:--在我第一次參觀北京時，我曾經(jīng)迷路了。--哦，是嗎？你可以請我當你的向?qū)�。might have done指過去可以做某事而未做；could do可能做；would have done 過去將要做某事；would do過去將要做某事。根據(jù)句意故選A。
點評：本題難度適中。情態(tài)動詞的完成式是高中階段的重難點之一，需要考生熟記它們的用法，在各類考試中經(jīng)常出現(xiàn)，它主要用于表示對過去情況進行推測或責備等。
即學即練: —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過去的事情表示推測，那么否定句用“can/could not+完成時”，故選B。
