老师，我妈妈身体不好，我必须要回中国照顾我妈妈。我于1周前已经定好一月6号的机票飞回中国。刚回国一直没网络，所以今天才发邮件给您。因为我已经在国内，很抱歉不能参加您安排的演讲。

Sorry to inform you that I cannot attend the speech as planned. Because of my mother's health reason, I already booked the flight ticket of Jan 6 and went back to China to take care of her. Sorry again to write to you so late due to I have little access to internet here.

==============希望合乎你的要求=============
