Перескажите текст. A pleasant Sunday day off almost turned to tragedy for two families at Ladram beach last week-end. The children in party had asked their parents to let them explore a bay situated at a distance. The parents hesitated but the children promised to be back within an hour. Soon they were climbing up the rocks and shortly afterwards were out of sight. They failed to notice the time passing, until the tide[1] was coming in quickly. Already the water was too deep for them to pass. The eldest of them was a good swimmer. Hi left the children sitting on the rock and swam back to raise the alarm. He struggled bravely in water and rushed to his parents at high speed. The waves were already round the children’s feet when the parents saved them. Fortunately the alarm came in time.
