Teacher Discussion Forums

I am an English teacher in Beijing , recently i came across a big problem that i was asked to teach oral English for a class of 67 volunteers for the 2008 Olympic Games . Now i am preparing the teaching plan. Could anybody give me some tips on that ? I badly need your help!

Awareness of the advantages which adult students have , i think , it is very important in teaching. Did anybody here ever attempt to teach English by comparing the distinctions and similarities between their native language? could you introduce that in detail?
