“hindsight” 的意思是 “事后的认识”，它常与介词 “in” 和 “with” 搭配使用，即 “in hindsight” 和 “with hindsight”，意思是 “事后看来，回过头想想”。

【例句】
In hindsight, we should have taken the train – we would have arrived at our destination much earlier.
事后看来，我们应该坐火车，那样就可以更早到达目的地了。

Taking the job, in hindsight, was my first mistake.
事后回想起来，接受这个任务是我犯的第一个错误。
