Great, thanks for the post! A few of my students and I just recently started a debate club at our high school and this will work wonders with them.
I especially like the sentences to start a debate with. This is very useful for Korean students who want to learn how to debate in English.
PS: If you're looking for some inspiration in relation to debates, check out the movie "The Great Debaters" with with Denzel Washington. It's moving! I think I'm gonna watch clips from it tomorrow during our club.
