2. The narratoe make a point of Marley's being dead because he though it was her fault.
3. Snowy winter can't affect Scrooge's behavior in the beginning because he was known being the grumpy old man who never smilled.
4. Before, he was the same as Scrooge, but he changed after he died because after he was a ghost, he didn't want him to have the same experience as his.
