假如你是 Sam，你的英国网友 Tom 今年九月份将作为交换生来常州学习。他给你写了一封信。请你给 Tom 写一封英文回信, 帮他解答疑惑。  

 Dear Sam,  

I'm very glad to have a chance to study in Changzhou this September. I hear there is a special day for teachers in China. I do think it's a good idea, but still have the following questions:

⒈When is Teachers' Day? What's the purpose and meaning of it?

 ⒉What do students usually do on that day? As an example, what did you once do to celebrate it?  

 I really want to do something to join in this interesting festival. Looking forward to your guide and help.  

 Yours,  

 Tom  

 注意： 1. 文中不得出现你的真实姓名和学校名称；

 Dear Sam,  

I'm very glad to share with you this special festival.
