情态动词是每年高考的热点也是难点。本题抓住两点：第一、时态。根据句中时间状语可以判断出是对过去事情的推测，故用情态动词+ have done；如果是对现在事情的推测，才用情态动词+v原形。第二、情态动词的选择。must为肯定推测，表示“一定”，could为不肯定推测，表示“可能”，这样就能选出正确答案。

考查情态动词。句意：——我的词典在哪里？我记得昨天放在这里了。——你或许放错了地方。“might have +动词+ed形式”表示过去可能完成的动作。根据所提供的情景Where is my dictionary? I remember I put it here yesterday.可判断出把词典放在某个地方发生在过去，所以要用“might have +动词+ed形式”。“should have +动词+ed形式”表示“(过去)本来应该做某事”。must意为“一定”，是肯定的推测，与所提供的情景的矛盾。might put表示现在发生的事。故选D。
