用second wind表达“再次振作起来”

当我们形容某人有 a second wind 的时候，这就是说他们恢复了精力，再次崛起或继续做什么事情。

• I usually feel a bit tired after lunch but get a second wind around 4pm.
• Observers said Barack Obama was judged to have lost the first Presidential debate with Republican challenger Mitt Romney, but got a second wind in the second and third debate.

值得注意的是，To throw caution to the wind 意思是把顾虑和担忧都抛在脑后，大胆的去做事。有时候也指办事欠考虑。

• Sometimes you have to throw caution to the wind and go with your heart. Do what you believe in.
• You know what? I‘m going to throw caution to the wind and bet all my money on that racehorse. I think it‘s going to win.
