    My folks bought their first house in the early 1940s after Dad got a better job in Marquette, Michigan. We lived just inside the city limits in what was still a rural area.

    In the spring of 1948, when I was 6 years old, my parents bought a calf (小牛) to replace our cow, which had been killed the year before. So one day we drove to a local farm and returned with a white and brown calf we named Tubby.

    We didn't own a truck, so Tubby rode home in the backseat of Dad's car with my 9-year-old brother Steve, and me. As you can imagine, the trip was a lot of fun for us kids.

    Later that summer, Mom thought it would be cute to take a picture of me sitting on Tubby's back. All went well unti1 the snap of the camera shutter sent Tubby charging off on a run, with me holding on for dear life. I lasted for about 30 feet before I hit the ground. Mom was quick enough to shoot a follow-up picture, so we had photos of me both on and off Tubby!

    When summer had passed, the day arrived for poor Tubby to fill our freezer I must have been somewhere else with my Mom on the fateful day, because I have no memory of how it happened. All I knew was that the barn was empty, and that we had plenty of meat for dinners.

    I hadn't lived on a farm like my mother, so I didn't understand that what happened to Tubby was not unusual. Livestock aren't meant to be pets, and most farm kids know and accept that truth.

    Whenever we had beef for dinner, I would tearfully, “Is this Tubby” This went on for a couple of weeks until Dad had finally had enough and declared, “No more cows!” That made me feel a little better about poor Tubby.

    Many of today's parents fondly remember childhood days spent playing outdoors. When children make mud pies and observe ants, it may seem like just fun and games, but the truth is the outdoor play is an important part of growing up healthily. The National Association for the Education of Young Children reports that outdoor play reduces (make…less) stress and restlessness in children and improves their attention.

    Outdoor play is the perfect way to fight against the childhood's obesity(being fat).Research shows that children who play outdoors are more fit and thin, according to the National Center for Physical Development and Outdoor Play. Children who spend time outside on a regular basis  also have healthier immune (免疫) systems. And playing outdoors is a good way to get enough vitamin D.

    Playing outside enables children to relax , reduces tension（紧张）and helps them solve problems. When children play outdoors, they learn to share and cooperate (work together) with one another. Kids who feel confident outdoors are likely to become able clever adults.

    The outdoors is a giant laboratory for learning that improves creative thinking and problem solving. Researchers have found that children learn best when their body, mind and spirit are involved (牵连的), and this appears in outdoor play. Outside activities develop all five senses, which create a powerful learning environment. The outdoors also lets children have the chance to explore (探究), experiment, form questions and create their own ideas about how the world works.

    Although there are the many advantages of outdoor play, time spent outside has been reduced for many of today's children. Kids today spend much more time in front of electronic media than children a generation (代) ago. The lack of outdoor play is tied to the childhood widespread obesity. And experts predict that the situation is so serious that this generation will have much trouble when they grow up. To get kids involved with the outdoors, encourage them to collect rocks, fly kites, climb trees, garden, camp, swim, go fishing, watch birds and butterflies or play games with other children.
