选择题
-----Where is my key? I remember I put it here yesterday.
--------You ______ it in the wrong place.
A．must put
B．should have placed
C．might put
D．might have put
答案
答案：D
考查情态动词表推测。因为是昨天的事，所以要用情态动词+have done结构。should have placed是应该做而实际上没做；might have put表可能性。句意：我的钥匙在哪里？我记得昨天我放在这了。你可能放在错误的地方了。所以选D。
