I'm sorry, Mr. Lee. Something has come up and have to cancel my appointment with you on Monday afternoon.

对不起，李先生，我有点儿事，星期五下午和你的约会我不能去了。

That's all right.

那没关系。

I wonder if we could change the time of our appointment to sometime early next week.

我想我们能不能把我们的约会时间换到下周早些时候。

Certainly. What about next Monday?

可以，下周一怎样?

Ok.

好吧。
