1. It’s a Pleasure./ A pleasure与You are welcome.等习语意义相同,用于当别人对你说Thank you. 时,即“不用谢”.例如：
－Thank you for coming to see me . －It’s a pleasure.－谢谢你来看我．－不用谢.
2. With pleasure与All right, No problem. I’d like to等习语意义相同.用于别人求你做某事,你很乐意去做的时候.例如：
－Could you post the letter for me ? －With pleasure.
－你能否替我把这封信寄走?－愿意效劳.
简单讲,It’s a pleasure用于事情发生之后,而with pleasure用于事情发生之前.
3. My pleasure?是相当正式的说法,意思是“我的荣幸之至”.你可以把它想成是It has been my pleasure to help you．（能够帮助你是我的荣幸.）的省略结果.这个句子还能有如下的用法：
－ "I'm glad to meet you．""The pleasure is all mine．"（"很高兴认识你.""哪里,我才是呢."）
－ "Could you help me for a minute?""My pleasure．"（"你可以帮我一下吗?""我很乐意."）
