—Couldn’t agree more! You know, someone _______ it. There are still good persons in Chongqing.

B

試題分析：考查情態(tài)動(dòng)詞+have done的用法：句意：--信不信由你，我今天早上把錢包落在出租車上以后應(yīng)該能失而復(fù)得。--很贊同，你知道，可能會(huì)有人拿的。重慶還是有很多好人的。Might have done過去可能會(huì)做，can have done一般用于否定和疑問句，should have done本該做而沒有做，must have done過去一定做了，這里表示人們只是有可能會(huì)拿他的錢包。選B。
