Don't eat the marshmellow

I've seen this speech before Lily gave it to us. I think this speech is not so well as Bill gates' speech. Because it seldom use the PPT to summary what he is talking about. Althought he play a film at the end of the speech, I think he still need some PPT for those who can't catch up his speed. Moerover, he has accent, I know it is my problem, but I realy can't understand his word sometimes.
I think I've some skill of speech in his speech. Including his structure of speech, his intonation, and his confidence. And most of all, I think I get more confidence in speaking english, because people like the speaker who has accent can't give a sppech so delecate maybe I can too.
