     As a parent you might never guess all the ways a good imagination benefits your child. It helps a

preschooler:

     Develop social skills

     As children play pretend, they explore relationships between family members, friends and co-workers

and learn more about how people interact. Playing doctor, they imagine how physicians care for their

patients. Playing house, they learn more about how parents feel about their children. Imaginative play

helps develop sympathy for others. If children can imagine how it feels to be left out of a game or to lose

a pet, they are better able to help those in need. They become more willing to play fair, to share, and to

cooperate.

     Build self-confidence

     Young children have very little control over their lives. Imagining oneself as a builder of skyscrapers

or a superhero defending the planet is empowering to a child. It helps them develop confidence in their

abilities and their potential.

     Boost intellectual growth

     Using the imagination is the beginning of abstract thought. Children who can see a king's castle in a

mound of sand or a delicious dinner in a mud pie are learning to think symbolically. This skill is important

in school where a child will have to learn that numerals symbolize groups of objects, letters symbolize

sounds, and so on.

     Practice language skills

     Kids who play pretend with their friends do a lot of talking. This helps boost their vocabulary, improve sentence structure and enhance communication skills.

     Work out fears

     Playing pretend can help children work out their fears and worries. When children role-play about the

big, bad monster under the bed, they gain a sense of control over him and he doesn't seem quite so big

or so bad. Imaginative play also helps kids let out confusing feelings they might have, such as anger

toward a parent or rivalry(竞争) with a new sibling(兄弟姐妹).

     To encourage your youngster's imagination, read to him every day. Books offer children the

opportunity to visit other worlds and create new ones of their own.

     For generations children have enjoyed reading the story of Peter Pan because Peter takes them on
