4. 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。

　　5. 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 #pletely 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。

　　6. 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
