I think some reasons why Barack Obama’s speech is so impressing. For instance, I took the election speech in 2008. First, he repeated same words. He said “Yes We can”. It’s impressed our minds. We can remember and understand easily. He used one strong word effectively. Second, many eye contact. He watched left side, right side, and sometimes behind! He did eye contact as hard as possible. I thougt many audiences feel he watched me. Finally, his speech speed is good. It’s easy to listen and understand speech contents. I think there is reason why Obama’s speech is impressing. I learned a lot from that speech.
