Passive and active voice. Introduction. Interactive and easy lesson done to teach EFL teenagers. This presentation shows step by step a whole 2 hour-class to teach passive voice. It is very interactive and gives all clues of what to show and when, links and attachements. It worked!!! (even with very "active" students :) !). I have made an extract of lots of ppts and info uploaded before by other colleagues (thank you for the support). This is an introduction.
