Write 300-400 words on this text, drawing on your analysis of the experiential functions. First, consider what kind of context this is, i.e. what is the field, the mode, the tenor. What is Obama doing in this speech, and specifically in this extract?
Then look at the patterns within the text with respect to choices in the experiential function: what kinds or process types are used? What kinds of participants? How does the grammar relate to the social/political context?
