选择题
—Believe it or not! I should get my lost wallet back after I left it in the taxi this morning.
—Couldn’t agree more! You know, someone _______ it. There are still good persons in Chongqing.
A．can have taken
B．might have taken
C．should have taken
D．must have taken
答案
答案：B
题目分析：考查情态动词+have done的用法：句意：--信不信由你，我今天早上把钱包落在出租车上以后应该能失而复得。--很赞同，你知道，可能会有人拿的。重庆还是有很多好人的。Might have done过去可能会做，can have done一般用于否定和疑问句，should have done本该做而没有做，must have done过去一定做了，这里表示人们只是有可能会拿他的钱包。选B。
