请再说一遍，好吗？对不起，我没听懂。

I beg your pardon? I don't understand. Sorry, I can't follow you.

对不起，请再说一遍那个词好吗？

I'm sorry, what was that word again?

youdao

第二种情况是也许你听不清我说的话。这时你可以说：“对不起，你能大点儿声吗？”或是：“请再说一遍好吗？”

Teacher:The second is, maybe you can't hear me clearly. In this case, you could say "Excuse me; can you speak up, please?" or "I beg you pardon?"
