You are welcome.只能填一個詞……anytime
更地道一點，可以回答
sure

見下邊的解釋：
Thank you - You're welcome.
This is the most common and accepted response.It can be used in basically any context.

Thank you - No problem / not a problem
This is a little more familiar.Something that two friends or two work colleagues might say to each other.

Thank you - My pleasure
This is a more polite way of responding.

Thank you - sure
This is a very short response which I personally don't really use.

Thank you - anytime
Again, this would be a familiar response, more among friends
