good morning everyone, how r u? May I introduce myself first, my name is xx(写黑板)，and you can just simply call me xx，I am very glad to be you xx teacher in the next few months time, and I really hope I could be your friend as well but not only your teacher. Well, this is my first lesson in my life(maybe not), so if there is any inconvenience between us, please do tell me, than I could make a little notice on that next time. And if you have any questions wanna ask, please don't be shy. Ok, just before I start this lesson, if you do have any questions about me right now, I am listening.(please do so/please ask) ....
