14.He was sorry for wasting the precious time when he _______ studied hard playing computer games at school.( 。
A.should haveB.would haveC.might haveD.must have

分析 他很遺恨,因為把在學校本應該認真學習的時間浪費在玩電腦游戲上.

解答 答案是A.本題考查"情態(tài)動詞+have done"的結構.should have done是虛擬語氣,表示"本應做但事實上卻沒有做";would have done是虛擬語氣,表示"本會…";might have done 既可以表示推測"也許已經(jīng)…",也可以是虛擬,表示"本可以…而實際上沒有".must have done表示推測,表示"肯定已經(jīng)…";根據(jù)句意可知,"本應該認真學習",由此判斷答案選擇A.

點評 要在正確理解情態(tài)動詞的基本含義的基礎上,整體理解語境中的情感態(tài)度,做出合理的判斷.
