A noted American psychologist once remarked that childhood is a magical period in one’s life．Indeed it is, for during         one undergoes a step-by-step transformation not only in mental capacity, but also in physical and verbal skills．Each step          an increase in the difficulty of a child’s conceptual and learning abilities．During the early stages of childhood, from infancy to about five, the child learns          skills including using the toilet, bathing and dressing himself independently．At this stage, he also learns to be very observant, curious, imaginative and creative．His ability to remember things also        at this stage． He remembers details that an adult may have difficulty in remembering．Gradually , he learns elementary skills in problem-solving．At school, particular in         classes, the child is especially creative．Given a piece of paper and some colored pencils, he draws a variety of         from his surroundings as well as from his           circle．It is not surprising to see a child draw a monster to represent an abusive father, and an angel to represent a loving and caring mother．
As he graduates to the later stages of childhood bordering on the teenage years, the child learns the           of human relations and socialization by interacting with his peers—his friends and schoolmates． He also learns to          with new life situations, including dates and part-time work． Given a tight schedule of schoolwork, the child learns to prepare his own schedules of work and play; the more________ and less serious ones manage to take time out of their busy schedules of assignments, reports and tests and examinations to go with their friends on relaxation entertainment．
