Natural speed, please. Try to pronounce properly and avoid noise in the background.
My wife Margaret and I were sitting behind a rock on the top of a mountain in the Highlands one day, nobody else around, perfectly silent, and Margaret said, 'I just heard a telephone bell ringing.'
'Oh,' I said, 'Margaret, there are no telephone kiosks up here.' But in the silence of the hills, you can imagine anything. I said, 'I often imagine things. I've heard babies crying in this silence. I've thought I heard symphony orchestra,' and Margaret said, 'I’m sure I heard a telephone ringing.' She got up and went round the back of the rock and there was a cow with a bell around its neck.
Thanks!
