The important things to have covered for next class, if you missed the class, are the grammar exercises (2, 3 and 4) on page 49 of the coursebook, and the reading exercises 2 and 3 on page 50 of the coursebook.
Homework was the vocabulary exercises (5 and 6) on page 50 of the coursebook, and read the text, 'Naturally High' on page 52 of the coursebook.
I will put links to TED talks up here next week.
