A person's true "spiritual hunger" should be cultivated from elementary and high school. At this stage, China must "save reading" at school, especially children's reading. "Reading is a weapon to eliminate ignorance, poverty and despair. " A nation s spiritual realm depends on the level of reading; a person s reading history is his mental development history; a school without reading can never have a real education, and learning without reading can only be called "training". What is the correct understanding of the purpose of this passage? ["Whether you develop the habit of reading from childhood will largely determine a person's spiritual state.", 'Reading should be an important part of school education.', 'The biggest difference between "learning" and "training" is that "training" is just the cultivation of skills.', 'Reading is the best way to cultivate "mental hunger".']
