不能肯定

The duplicitous nature of Ming was played so well by Lau that by the last scene, you are still not sure whether he truly wants to be good, or was it all just an act that he has perfected?

刘德华把刘健明的双重性格演绎得如此之好，以致于直到最后一个镜头，你都不能肯定是他真的想做一个好人，又或者这一切不过是他漂亮的一出戏。

I think that's right,but I am not sure either.

我想那是对的，不过我也不能肯定。

I'm not sure how Emilie heard about Damour. It might have been at school – where she learns, to my great regret, about events like 9/11 and the Holocaust. Or it might have been at the dinner table, where I fear I may have let my guard down the other night and vented my feelings after I read about his death.

我不能肯定Emilie在哪里听说了Damour的事情，可能是在学校，让我遗憾的是她在学校也知道了911和HOLOCaust，也或者是在吃饭的时候，我可能比较放松，宣泄了我对Damour死讯的感受。

Even though i think it'right, i can't make sure of it.
