今天在电影中看到一个词“pretext”, 这个词的意思是“借口”，那他与常用的excuse有何区别呢？我们先看一下字典。
pretext 事前编造的借口
Collins：A pretext is a reason that you pretend has caused you to do something.
您看到了吗，pretext=pre（事先） text （说辞），合起来就是“事先编好的说辞”，即“（忽悠人的）借口。”我们看一下例句：
1. They wanted a pretext for subduing the region by force. 他们需要一个用武力征服那个地区的托词。
2. He left the party early on the pretext of having to work. 他借口有事要处理，早早离开了聚会。
下面看一下excuse的解释，
excuse，事后逃避的借口
Collins：An excuse is a reason that you give in order to explain why something has been done or has not been done, or in order to avoid doing something.
您看到了吗，excuse指的是在做了某事后，为了避免发生不愉快，给出一个理由解释自己（错误的）行为。例句：
1. It is easy to find excuses for his indecisiveness. 为他的优柔寡断寻找借口是件容易的事。
2. If you stop making excuses and do it you'll wonder what took you so long. 如果你停止辩解而开始行动，你就会惊讶是什么让你耗费了这么长的时间。
no excuse for something, 没有借口
此外，no excuse for something意为“没有理由（表不满）”，如：There's no excuse for behaviour like that. 像那样的行为毫无道理。
