小伙伴们需要打断别人的谈话，插话进去的时候一般有这么几个目的：
1 给某些人传递信息
2 迅速的提问一个问题
3 发表自己的观点

4 打断别人谈话，想要参加进来

母语英语系国家里，说话自然要用英语，那么打断别人谈话的时候，自然也要遵守英语母语系国家的礼貌啦！
那么，如果你插话的目的是为了传递信息，那么你可以利用下边这种形式，达到友好插话的目的：
I'm sorry to interrupt but you're needed (on the phone / in the office / in the classroom / etc.)
Sorry for the interruption. It's Jim / Peter / Mary （任意名字）on the phone.
Pardon me, but I have John on the phone.
Excuse me, could I get a signature / an answer / a cup of coffee quickly?                                                                                                                                          
但你想要插话进去，询问一个不相关的问题的时候，那么可以这么说：
At times we need to interrupt to ask an unrelated question. These short phrases quickly interrupt to ask for something else.
I'm sorry to interrupt, but this will only take a minute.（一定要先说Sorry，这是基本礼貌）
Sorry for the interruption, but could you (answer a quick question / help me for a moment / give me an opinion on ……?
I'm so sorry. This will just take a minute.
I apologize for the interruption, but I have an important question.
在没有插话进去之前，一定要先说Sorry！其实对于好多人来说，即使你说了Sorry，人家都未必愿意理你捏~

如果你想要参与进去别人正在进行的谈话，那么可以以问问题的方式：
Could I jump in?
Could I add something?
Can I say something?
May I interject?
用问题，以询问的口气是打断别人谈话的友好方式！这种等同于“你愿意吗？”的询问！

类似于在班级课堂上的一些讨论中，如果自己被忽视了，没有人问你的个人意见，那么一定要“友好”提示，明确的表明自己的观点：
Would you mind if I joined the conversation?
I couldn't help overhearing. 自己不是其中一员时使用。
Sorry to butt in, but I think / feel ...
If I may, I think / feel ...

如果，别人打断了你的话，而你不想被打断，想要将话题的关注点再次引到自己身上，那么可以适当的表明自己态度，当然，如果你是打断别人说话的那个，你听到别人这么说，就代表人家不喜欢你打断他们的谈话啦！
Please let me finish.
Let me complete my thought.
Would you please let me finish?
Can I continue, please?
同样，要加上PLS等，表示自己的友好！

在你同意别人打断你的谈话的时候，那么可以用下边的话引出插入者的问题的！
No problem. Go ahead.
Sure, what do you think?
That's OK. What do you need / want?

在别人打断你们谈话之后，如何继续进行谈话呢？
As I was saying, I think / feel ...
To get back to what I was saying, I think / feel ...
I'd like to return to my argument.
Continuing where I left off...
继续装作若无其事的继续谈话！

给小伙伴们举俩栗子哈！

Helen: ... it's really amazing how beautiful Hawaii is. I mean, you couldn't think of anywhere more beautiful.
Anna: Excuse me, but Tom is on the phone.
Helen: Thanks Anna. This will only take a moment.
Anna: Can I bring you some coffee while she takes the call?
George: No thanks. I'm fine.
Anna: She'll be just a moment.
这样说起来，语气温婉，即使是打断别人谈话，也不会让人觉得突兀，很有礼貌！

Marko: If we continue to improve our sales in Europe we should be able to open new branches.
Stan: Could I add something?
Marko: Of course, go ahead.
Stan: Thanks Marko. I think we should open new branches in any case. If we improve sales great, but if we don't we still need to open stores.
Marko: Thank you Stan. As I was saying, if we improve sales we can afford to open new branches.
打断别人谈话，要获得别人的允许之后，才能发表自己的观点！

打断别人的谈话也是可以以友好的方式的，就看小伙伴们自己的说话水准啦！
