问题补充：
------ Where is my dictionary ? I remember I put it here yesterday .
-------- You it in the wrong place .
A. must put
B. should have put
C. might put
D. might have put
答案：
A. must put
B. should have put
C. might put
(答案→)D. might have put
解析：句意：—我的字典在哪里？我记得昨天放在这里的。—你可能放错地方了。根据句意说明是对过去情况的推测，使用情态动词+have done.排除AC。Should have done本应该做某事实际上去未做，是虚拟语气的用法。Might have done也许做了某事；是对过去所发生事情的推测。选D.
