Hear or listen (to)?
hearing is an event
Suddenly I heard a noise. Someone was in the garden.
Did you hear the thunder last night?
[on the phone]
The line is very bad. I can’t hear you.
listening is an action
I listened very carefully to what she said and wrote it all down.
Do you listen to the radio in bed?
George! Listen to me! I have something important to tell you.
Sometimes we can use either hear or listen to, depending on whether we want to emphasise the event or the action:
Did you hear that interview with David Beckham on the radio yesterday? (emphasis on the event)
Did you listen to that interview with David Beckham on the radio yesterday? (emphasis on the action)
I love hearing/listening to the sound of falling rain.
