Question

He______ his work, otherwise, he wouldn’t be enjoying himself by the seaside.

A．must have completed	B．should have completed
C．ought to complete	D．must complete

Answer 1

A

試題分析：句意：他一定是完成了他的工作，否則他不會(huì)在海邊玩得那么開(kāi)心。A. must have completed對(duì)過(guò)去的肯定推測(cè)；B. should have completed本應(yīng)該完成，實(shí)際上沒(méi)完成；C. ought to complete應(yīng)該完成；D. must complete必須完成。表示對(duì)現(xiàn)在的推測(cè)。故選A。
考點(diǎn): 考查情態(tài)動(dòng)詞表推測(cè)的用法。
