刚学英语时，人们最先学会的是 thank you 和 thanks。随着学习的深入，可以按场合选择更丰富的表达。
表示感谢
- Thanks a million.万分感谢。
- I owe you one.我欠你一个人情。
- Thank you very much.非常感谢。
- Thank you for your help. / I appreciate your help.谢谢你的帮助。
- I truly appreciate your timely help.我真心感谢你的及时帮助。
- I thank you from the bottom of my heart.我衷心感谢你。
- I'm grateful to you for all you have done for me.感谢你为我所做的一切。
- Words cannot express how thankful I am.言语无法表达我的谢意。
- All I can say is — thanks.我只想说：谢谢。
- I want to express my deepest gratitude to you.我想向你表达深深的谢意。
怎样回应别人的感谢
- You're very welcome.不客气。
- You're more than welcome.千万别客气。
- My pleasure.这是我的荣幸。
- It was my pleasure.很高兴能帮上忙。
- It was nothing.没什么。
- Don't mention it.别客气。
- Not at all.不用谢。
- Anytime.随时乐意帮忙。
感谢可以用言语，也可以用行动。一句真诚的谢谢，往往能拉近人与人之间的距离。
