-----You must have enjoyed using your new camera on the trip to Tibet.
----- I would have, but I it in David’s car when he drove me to the airport.
A. had left
B. have left
C. were to leave
D. left

A. had leftB. have leftC. were to leave(答案→)D. left解析：考查情景交际和时态。句意：--在去西藏的旅行中，你的新相机一定给你记录了许多美好的回忆。--本来是这样的，但是，大卫送我到机场时，我把相机落在他的车上了。根据答语可知，“我”把相机落下了，没有带相机是事实，不需要用虚拟语气；根据第一句可知，是发生在过去的事情，用一般现在时，故选D。

谢谢了
