1、如何拒绝邀请
你要做的事情就是：
1)说出感谢
2)说“不”
3)给出理由
还有可能：
4)建议其他时间或日期
举个例子
Thank you so much for the invitation, but I'm afraid I have a prior engagement.
非常感谢您的邀请，但我已经有约了。
更正式一些
Thanks for the invitation!I'm really sorry, I can't come - I've already got other plans.
感谢您的邀请！不过很抱歉我不能来，因为我已计划了其他事情。
还可以说
I'd love to, but I'm afraid I can't.Would another time be possible?
我很想去，不过恐怕不行。可以换个时间吗？
I'm very sorry, but I won't be able to make it.Another time would be great, though!
很抱歉，我无法去。要是换个时间就太好了！
It's a lovely idea, but I won't be able to join you this time.
好主意，但我这次无法参加了。T
hat's very kind of you, but…
您太好了，不过...
Could I join you later?I just have to finish something.
我可以稍后加入你们吗？我必须先完成一些事情。
Today's not so good - how about tomorrow?
今天不太合适，明天如何？
2、如何打断唠叨
如果对方喋喋不休，自说自话，而你又有别的想法，不如这样打断对方：
I understand what you're getting at, but (I'm just not interested/I just can't /it just won't be possible) at the moment.
我了解你所说的事情，只是我现在（不感兴趣/无法去/不可能去）。
或者直呼其名来强调语气
Look, Michael, I'm sorry, but it's just not going to be possible at the moment.
迈克尔，实在抱歉，但是现在确实不可能。
