For those who wants to study English from President Obama,
I want to share the link below provided by New York Times.
http://www.nytimes.com/interactive/2012/11/06/us/politics/06-obama-election-night-speech.html
You can see Obama’s victory speech for the election of 2012 with a movie and scrolling scripts.
That is quite helpful to learn various aspect of both English and “Presidential English.”
Listen and read at loud over and over. Then you’ll get Obama’s way of speaking!
