When talking to somebody very close, you could even just say "Huh!?" or 你很趕嗎！？(Are you in a rush!?)

<p>I have a series of useful phrases from <a href="http://www.jukuu.com" rel="nofollow">Jukuu</a>, that assist learners in developing conversations and learning new word/phrases. Which of these would be more appropriate for talking to a stranger?  Would I choose a different phrase for a doctor or for a family member? If other phrases are more appropriate please let me know.</p>

<p>謝謝！</p>

<pre><code>Will you speak a little more slowly?
请你说得再慢一点，好吗?

I am sorry, sir. Can you repeat that more slowly, please?
对不起，请你再说慢点。

I'm sorry, can you repeat that.
对不起，您能重复一下吗？

A: Can you repeat that, please?
甲：请您再说一遍好吗?

Sorry, I don't understand.
对不起，我没明白。

<p>Use phrase x when talking to family members (etc.)</p>

Well, I think the translation are quite close to their literal meaning, so use them depend on the situation. The first 4 generally express your interest in continuing the conversation, but the last one may not.
