He _______ have completed his work；otherwise, he wouldn’t be enjoying himself by the seaside.
A．should B．must?C．wouldn’t D．can’t
B

試題分析：考查情態(tài)動詞用法。Should have done本應該做某事，實際上卻未做；must have done一定做了某事；can’t have done不可能做了某事；句意：他一定完成了作業(yè)，要不然，他不會在海玩得那么開心。根據(jù)后半句話說明他在海邊玩得很開心，那么他已經(jīng)完成了作業(yè)，這是一個過去發(fā)生的事情，使用“情態(tài)動詞+have done”對過去發(fā)生的事情進行推測。故B正確。
點評：情態(tài)動詞 + have done這是歷年高考熱點之一，可表示“推測、責備、懷疑”等多種意義。情態(tài)動詞的使用是高中英語學習的一個重點，也是高考中的一個重要考點。由于每一個情態(tài)動詞都含有相應的說話者的語氣，所以我們既要了解每個情態(tài)動詞的基本用法，又要體會說話者的語氣。
