Homework reminder:

Write 5 sentences making positive predictions starting with: I think...
Example: I think he will be difficult to convince. 
And 5 sentences making negative predictions using I don't think...
Example: I don't think I'll be able to call you tomorrow.

You also have to do the last exercise on the paper I gave you, I think it was number 10. Unfortunately I don't have the book with me right now, so I am not sure. I will confirm it later.
