核心问题
To think that all that money has been wasted! 请问 to think 的隐含的主语是什么？所有的英汉词典都将 to think 译为“想想”，是让谁“想想”呢？是让听话人“想想”？
词典解答
根据CGEL的解释,to think的逻辑主语一般是说话人(I)。to think that可以释义为It surprises me to think.这种句型主要用于表示惊讶(参见that):
-
To think that he should be so mean! (CGEL) 真没想到,他竟然这么卑鄙!
-
To think he knew about it all the time! (Eckersley) 真没想到他竟然一直都知道这件事！
-
To think that she could be so ruthless! (CGEL) 简直无法想象她竟然能够那么冷酷无情!
-
To think of his not knowing anything about it! 简直想象不到他对此事竟然一无所知！(参见 to )
