——Do you know where David is? I couldn’t find him anywhere.
——Well, he_______ gone far—his coat’s still here.

A．shouldn’t have B．mustn’t have C．can’t have D．wouldn’t have

C

解析試題分析：句意：--你知道大衛(wèi)在哪里嗎？我到處找不到他。 —大衛(wèi)的上衣還在這里，因此他肯定沒走遠(yuǎn)。can’t＋have done表示對(duì)過(guò)去發(fā)生的行為的否定推測(cè)“過(guò)去不可能做”，shouldn't  have  done ：本不應(yīng)該做某事（而實(shí)際上做了），must表示推測(cè)的時(shí)候應(yīng)該用肯定句，wouldn’t  have done過(guò)去不會(huì)做而做了，選C。
考點(diǎn)：考查情態(tài)動(dòng)詞+have done的用法
