What are you doing?

Have you seen this question on your twitter account? What... you haven't got a twitter account? Well, this is a good example of present continuous tense, and it means.......? Yes, that's right, it means 'what are you doing, now'. You can also use tomorrow, as in, 'what are you doing tomorrow?' Or you can use other time expressions like 'later','this morning', 'tomorrow morning', 'tonight', 'later this week'. That's the present continuous. Use it on twitter, and practice saying what you're doing 'now', or what you're 'planning' to do, or for making 'arrangements'. Oh, by the way, join me on twitter while you're there at http://twitter.com/kiwicarioca. Enjoy the animation!
