This clip is from an episode The Adam Buxton Podcast, which is a very funny and entertaining podcast and a great way to practise listening to natural conversation. In this episode, Adam is chatting to the British comedian Tash Demetriou.
For context, Adam has just asked Tash to update him on recent events in her life.
…what have I been up to…
The phrase “What have you been up to?” is a very natural and relaxed way of asking someone to tell you about recent events in their life.
“What are you up to?” is a way of asking someone what they are doing now – you might ask someone this if you bump into them in the street, for example.
