Pen

Lift the pen,

Open the book,

Line after line of dense text,

It tells the story of a spaceship from the vastness of space.

Poverty hinders people's vision,

Change opens up social development,

Metaphor studies the micro level,

Humanism is a philosophical concept.

Maslow's hierarchy of needs has a loving perspective,

Lewin's behavioral formula is related to the individual and the environment.

Kohlberg proposes the stages of moral development,

Bandura reinforces the habit of human learning behavior.
