Question

— Happy birthday!
— Thank you! It’s the best present I _______ for.

A．should have wished	B．must have wished
C．may have wished	D．could have wished

Answer 1

D

考查情態(tài)動(dòng)詞+have done表推測用法。句意：“—生日快樂！—謝謝！這很可能是我希望得到的最好的禮物。”should have done“本應(yīng)該做（但實(shí)際上未做），只表虛擬”；must have done“過去一定做過某事”；may have done“過去可能做過某事”；could have done“過去很可能做過某事”。后三個(gè)均可表推測，就可能性程度而言，must 最大，could 其次，may 更次之，might 最小。
