have
done。故选B。【出处:21教育名师】

A.
must
put
B.
should
have

C.
might
put
D.
might
have
put
答案及解析:D
句意:——我的词典在哪里?我记得
(?http:?/??/?www.21cnjy.com?)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。
