在英语里，如果我们说某事是“a long shot”，那么意思就是“实现此事的机会不大”。

I’m looking for a first edition of Alice in Wonderland for my mother’s birthday. I know it’s a long shot, but do you have one in stock?
My favourite football team is in the cup final at the weekend. I think we could win, but it’s a long shot.
We could ask the company to replace your broken smartphone for free. It’s a long shot, but it’s worth trying.
值得注意的是，还有一个与shot相关的短语“a shot in the dark”，其意思是“猜测”。



A: How old do you think I am?
B: I’ll take a shot in the dark and say 40.

First learnt the word "shot" as the meaning of "chance" from the musical Hamilton.
shot 作为“机会”意译还是从《汉密尔顿》学的~
I am not throwing away my shot （我不会错失良机）


a long shot 直译射程长 →打中的机会小→机会渺茫，很好玩的理解过程

I will give one more example of "a long shot":
I admit she's talented in many ways, but being a professional singer is really a long shot.
我承认她在许多方面都很有才干，不过要当一个职业歌手实在是不太可能。
