You maybe surprised to learn that one of the best steps you can take to protect your health is to step outside and spend some time in the grass, dirt and water．
Our ancestors enjoyed the healing power of na
ture，and now scientists are starting to catch up．According to research in recent years，just having a view of nature has been shown to improve hospital patients' recovery and reduce illness rates among office workers．Also，exposure(曝露) to wildlife，horseback riding，hiking，camping and farms can be helpful for a variety of health conditions in adults and children．
Much of this type of research is focusing on children，and in fact an entire movement has quickly developed to connect kids with the healing power of nature．
Obesity（肥胖）．Rates of childhood obesity have grown sharply in recent years，and this is partly because of reduced outdoor activity time．Increasing the time students spend learning about nature，both in and outside the classroom，would help solve this problem．Such lessons are often more attractive for students and often lead them to become more active outside．
Attention deficit hyperactivity disorder（ADHD）（注意力缺失症）．Exposure to ordinary natural settings in the course of common afterschool and weekend activities may be effective in reducing attention deficit symptoms in children．Participation in green activities—such as nature walks—helped ADHD patients from a wide range of backgrounds to stay focused and complete tasks．
Stress．Access to nature，even houseplants，can help children cope with stress．
Depression and seasonal emotional disorder．Major depression requires medical treatment，but physical activity，especially outdoors，can help ease symptoms．For your average case of winter blues，experts suggest spending time outside every day and，if possible，taking the family to a sunny vacation spot in midwinter．
Experts emphasize that you needn't go to wilderness preserves to enjoy nature's benefits—simply walking in a city park or growing in a rooftop garden can make a difference

优百分课时互动系列答案Ever since Jerusha started her college, she began to write letters. Through a series of letters, from freshman to senior in college, she shared her life and study with an unknown gentleman, who never wrote back. Here is the very first letter.
| Dear Mr. Kind, Here I am! I traveled yesterday for four hours in a train. It's a funny experience. I never rode in one before. College is the biggest, most confusing place — I get lost whenever I leave my room. I will tell you more later when I'm feeling less puzzled. Now I want to write a letter first just to get me familiar to you. It seems strange to be writing letters to somebody you don't know. It seems strange for me to be writing letters at all — I've never written more than three or four in my life, so please overlook it if they are not a model kind. Before leaving yesterday morning, Mrs. Lippett and I had a very serious talk. She told me how to behave, especially towards the kind gentleman who is doing so much for me. I must take care to be very respectful. I have been thinking of you a great deal this summer; having somebody take an interest in me after all these years makes me feel as though I had found a sort of family. It seems as though I belonged to somebody now, and it's a very comfortable feeling. I must say, however, that when I think about you, my imaqination has very little to work upon. There are just three things that I know: I .You are tall. II .You are rich. III. You hate girl. I suppose I might call you Dear Mr. Girl-Hater. Only that's rather unpleasant to me. Or Dear Mr. Rich-Man, but that's unpleasant to you, as though money were the only important thing about you. Maybe you won't stay rich all your life; But at least you will stay tall all your life! So I decide to call you Dear Daddy-long-legs. I hope you won't mind. It's just a private pet name — we won't tell Mrs. Lippett. The ten o'clock bell is going to ring in two minutes. Our day is divided by bells. We eat and sleep and study by bells. There it goes! Lights out. Good night. You can see how strictly I obey rules due to my training in the John Grier Home. Yours most respectfully, Jerusha Abbott |
