群聊时如何“插嘴”课堂讨论时，公司开会brainstorming时，同学聚会争论某个问题时，都需要我们适时表达自己的意见。怎么样表达才能让别人听到并注意到呢？昨天，我们说了表达自己意见的不同方式。今天，我们来说说讨论时如何提出疑问。
1. 疑惑追问
Just to clarify,... 我想确认一下.。.
May I ask a follow-up question? 我能就你说的问个问题吗？
Could you say more (about it)？ 你能多解释一下吗？
Could you elaborate on this? 你能详细解释一下吗？
上述的句子都是在听了别人的看法之后，不确定自己是否理解正确，所以追问，让别人详细解释一下。
2. 会议报告、演讲之后提问
That's an amazing model/useful concept, but it occurred to me that [this/something] might also play a role....Have you considered ...?
Thanks for your talk. I completely agree with your conclusion, but as I'm sure you're aware, Dr. XX explains this in a different way, and I was wondering if you could address her theory。
这种提问的开场白多是肯定之前报告和演讲的意义，然后再提出自己的问题。
"but as I'm sure you're aware"完全是给对方一个台阶下，可能那个理论他根本没有考虑过。但是如果对方是比较资深的，我们也需要客套一下。
3. 寻求帮助
I was wondering if I could talk to you about.。.
I was hoping that if I could talk to you about.。.
I was wondering if it'd be possible that you.。.
上述句子均表示：不知我是否可用跟您请教.../您可否.。.
这种句式一般都是用过去时，在email里面也是如此。而且，虽然was wondering/hoping这种进行时看起来很怪，但是用法就是这样子的
Sorry to bother you, Professor X.... XX教授，抱歉打扰您。
I realize this is an unusual request... 我知道这样的要求有些不合常理。
I realize that you are very busy... 我知道您很忙。
Thanks for your time。谢谢您抽出宝贵时间。
Thanks in advance for your help。先谢谢您的帮助
It would be great if you could... 如果您能够.。.那就太好了。(这个是最常用的，尤其是email里面)
