realisation

I was hit by the realisation that I might die.

我认识到我可能要死了。

The realisation that she was gone was like a knife thrust.

意识到她已走了让人心像刀扎了一样。

It seemed that the realisation of his life’s dream oppressed him with overjoy.

夙似乎使他欣喜若狂。

The realisation that the murderer must have been a close friend came as a shock.

意识到杀人凶手一定是个密友，大家都很震惊。
