当碰到困难时，英语中常用的表达是 "When in trouble, when in doubt, run in circles, scream and shout." 这个表达来源于拉丁语的谚语 "Quando omni flunkus, moritati"，意思是"当一切都失败时，做好死亡的准备"。一些例句如下：
When things get tough, just remember the old saying: "When in trouble, when in doubt, run in circles, scream and shout."
I always try to keep a positive attitude, but sometimes it's hard not to panic. That's when I remind myself: "When in trouble, when in doubt, run in circles, scream and shout."
If you ever find yourself in a difficult situation, just remember: "When in trouble, when in doubt, run in circles, scream and shout." It might not solve the problem, but at least it will give you something to do!
