‘Many English - learners say:
“When I listen to the BBC or to CNN, I can’t understand anything
because they speak much too fast.”
But it is not so because you haven’t got exposed to spoken English.
Try to listen to English for at least 30 minutes daily for 30 days
without break. Feed your ears with English while you’re feeding
your stomach with breakfast. By and by you can capture and understand English.’
