【原】a leopard can't change his spots 江山易改本性难移

江上易改本性难移，就像 a leopard can't change his spots，表面意思“豹子不会改变他的斑点”，这句谚语就是比喻本性难移。十年树木百年树人，要改变一个人的性格谈何容易。它寓意：

one cannot change who they are

一个人无法改变他们是谁

the inherent traits in a person remain as they are even if they actively seek to change them

一个人的内在特质会保持原样，即使他们主动寻求改变

it is a notion that the innate or inborn nature of things cannot be amended

这是一种观念，即事物的固有或先天的本性是不能改变的。

例如：

He is bound to fail the exam again, a leopard cannot change his spots after all.

他一定会再考不及格的，毕竟本性难改。

She is still going after married men. It is impossible for a Leopard to change his spots.

她还在追求已婚男人，真是本性难改。

The teacher tried to be kind to her students, but a leopard can’t change its spots, she was still very mean.

老师试图对学生好一点，但她还是很刻薄。

After our breakup, he came crawling back, trying to convince me that he'd changed, but I know that a leopard can't change its spots.

我们分手后，他爬回来，想让我相信他变了，但我知道江山易改本性难移。

Bill may say he'll stop being so jealous after Cindy marries him, but I doubt he will. A leopard can't change his spots.

比尔也许会说辛迪娶了他以后，他不会那么嫉妒了，但我怀疑他会不会。毕竟江山易改本性难移。

除非是非常之必要，不然是不会想到要改变自己的本性，天生我材必有用，我们要充分利用自己的优势来创造属于自己的未来，我的人生我做主。
