1) I have been playing tennis, so I\'m quite tired. 2) Luke says he has never met anybody who plays the xylophone. 3) Have you followed the new series that\'s on TV at the moment? 4) My fingers are sore because I have been practising the guitar all morning. 5) We have been waiting for an hour and our dance teacher still isn\'t here! 6) My dad has taken up a new hobby - cooking!
