This is a very simple, unattractive .ppt. I use this as a way to get students to talk. So far they seem to like it. (Chinese 18-22y.o) Each slide has a topic/situation to talk about. I make the students debate in pairs. You can make this a more structured activity by adding to each slide various phrases to learn/use or introduce new vocabulary. I just use it as a fun side activity. Topics range everything from school uniforms to global issues.
