当某人帮你解决了大难题时，你可以说 “ You are a star! 你简直就是明星！” 意思是，你真厉害或你真棒。
- The dinner party I invited my boss to was a success thanks to Mary. She cooked the main dish. She's a star!
- I've got so much work to do. I'm happy you've offered to help. You're a star!
值得注意的是，当有什么事情偶然发生，类似不幸中的万幸，人们可能会说 thank your lucky stars.
- John thanked his lucky stars his teacher didn't catch him cheating in his exams. He'd have been immediately expelled from school.
