Question

【題目】George _________ too far. His coffee is still warm.
A.must have gone
B.might have gone
C.can't have gone
D.needn't have gone

Answer 1

【答案】C
【解析】考查情態(tài)動(dòng)詞+have done。喬治不可能走得太遠(yuǎn)了。他的咖啡仍然是溫的。can't have done是對(duì)過(guò)去的否定推測(cè)；must have done過(guò)去一定做了某事；might have done過(guò)去可能做了某事；needn't have done過(guò)去本不必做某事。故選C。
