Catherine:     Excuse me.
Man on the phone:   Yes?
Catherine:     Sorry to interrupt your phone call, but...
Man on the phone:   What's wrong?
Catherine:    It's just that this is a library and everyone
is trying to study.

Man on the phone:   Oh dear! Am I talking too loudly?
Man on the phone:   Of course, I'll go outside. Sorry about that!
Catherine:     Yes. Could you talk more quietly, please?
Catherine:     That's ok.
Man on the phone:   Of course, I'll go outside. Sorry about that!

凯瑟琳：         不好意思。
讲电话的人：  嗯？
凯瑟琳：         很抱歉打断你讲电话，不过……
讲电话的人：  有什么问题吗？
凯瑟琳：         这里是图书馆，大家都在念书。
讲电话的人：  哎哟！我说话太大声了吗？
凯瑟琳：         是啊，可以请你小声一点吗？
讲电话的人：  当然，我会到外面去讲，很抱歉吵到你了！
凯瑟琳：         没关系。
