Hello, teacher! I am a freshman in China, and my English listening is not very good, can you add English subtitles, so that it is easier to understand, thank you.
Wonderful, thanks. I love the archival footage of Ed Carpenter. I wonder what he might think of those ubiquitous mobile devices that we use to communicate with one another. Just es a screen is now in every room, there is a mobile in every hand. How does this change us as human being, social beings?
