Danny <em>hasn't been drawing</em> for very long, but he's already <em>become</em> very good at it. He <em>didn't start</em> drawing until his family moved from Birmingham to Chester two years ago. But since then, he <em>has been</em> a member of the Chester Community School art club.
This weekend, Danny <em>has been drawing</em> a very big picture for a school art competition, but he <em>hasn't finished</em> it yet. It's Sunday afternoon now, and Danny is very tired because he <em>has been working</em> on the picture all weekend.
