一、关于道谢
【道谢用语】 
1. Thank you (very much). / Thanks a lot. / Many thanks.
2. Thanks for your help. / Thank you for the lovely gift / for your invitation.    
3. It’s very kind / nice of you. 
4. I can never thank you enough. / I really don’t know how I can thank you enough.
5. Thank you all the same.(用于当别人因某种原因没能帮你时。)
【对道谢的应答】 
1. Not at all.   
2. That’s all right. / That’s OK.
3. You’re welcome. 
4. Don’t mention it.
5. It’s my pleasure.
6. I’m very glad you enjoyed it.  
注意:
在答复别人的道谢时,不可受汉语习惯的影响回答出诸如This is what I should do或It’s my duty等答语,因为这给人“不是出于自愿,而是为完成任务不得已而为之”的感觉。
