【问】 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”?

【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Itsurprises me to think.这种句型主要用于表示惊讶(参见that)：

1.To think that he should be so mean! (CGEL)

真没想到，他竟然这么卑鄙。

2. 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!

3. To think that she could be so ruthless! (CGEL)

简直无法想像她竟然能够那么冷酷无情!

4. To think of his not knowing anything about it!

简直想像不到他对此事竟然一无所知!

(参见to+动词不定式短语!)
