You can listen in on your phone, on your laptop, on digital radio, through a smart speaker. And what's more, the radio station also offers podcasts on a varied number of subjects. As I type this message I'm looking at the available podcasts and they include:
"The premier football podcast from The Times, with the finest writers reviewing and previewing all the action from the 2019/20 season."
"After more than a decade in London, Danny Fortson returns to Silicon Valley to meet the techies trying to change the world - and make loads of money while doing it." And others.
Communication requires both listening and speaking, oral comprehension and oral expression. This is one way of practising oral comprehension.
