What is Scrooge’s new approach as the clock strikes one?

This sounds like the ghost of Christmas present visit. I'm not sure what you mean by "new approach". Scrooge wakes up, and the bell of a neighborhood church rings from six until twelve, then stops. He wonders if he slept through the day and into another night. He looks out the window to an empty scene. He worries over Marley's ghost and wonders if it was a dream. He remembers the ghost's warning of a visit at one at night, and waits. The hour arrives, a flash of light comes in the room, his bed-curtains are drawn aside, and the figure of a small old man appears.
