不好意思，今天因为skype 的问题不能上课了。Let's find another time next week to make the missed lesson up. 好吗？

Today is Dec. 22nd (Wednesday). I didn't see you online today??? Are we still scheduled to meet at 9:15pm CST? I changed it so many times that I am forgetting now :/ - Sorry.
Over the past two weeks, I have been studying the following lessons:
1. Airplane Ticket (with Peter, the Canadian) 改日期。
2. National Day 国庆节
3. Snacks 零食
