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 nature，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．

　Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snowblindness ,when exposed to several hours of“ snow light”.

　　The United States army has now determined that glare from snow does not cause snowblindness in troops in a snow -covered country. Rather ,a man’s eyes frequently find nothing to focus on （聚集） in a broad space of snow- covered without- grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid （流 体） which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.

　　Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow - covered landscape. Even the scouts themselves throw lightweight, dark - colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow -blanketed landscape. By focusing their attention on one object at a time. the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.

To prevent snowblindness caused by the strong light from snow, wearing glasses or not ________.

　　A. depends on whether the snow is white enough

　　B. makes no difference

　　C. makes much difference

　　D. depends on whether the snow is thick

When the eyes are tired, tears flow out ________.

　　A. to clear the vision

　　B. to make the eyes stop searching

　　C. to make the vision unclear

　　D. to produce more and more liquid

Snowblindness can be avoided ________.

　　A. by moving one’s gaze back and forth

　　B. by walking ahead and keeping looking around

　　C. by making up for the discomfort of one’s eyes

　　D. by providing the eyes with something to focus on

Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir (知识库) which may be called experience, and the college students will find that every craftsman (工匠) has something he can teach and will generally teach gladly to any college student who does not look down upon them. The information from them differs from that in textbooks and papers chiefly in that its theoretical (理论的) part -- the explanations of why things happen -- is frequently quite fantastic (神奇的) . But the demonstration (示范) and report of what happens, and how it happens are correct even if the reports are in completely unscientific terms. Presently the college students will learn, in this case also, what to accept and what to reject. One important thing for a college student to remember is that if Aristotle could talk to the fisherman, so can he.

　　Another source of knowledge is the vast store of traditional practices handed down from father to son , or mother to daughter, of old country customs ,of folklore (风俗). All this is very difficult for a college student to examine, for much knowledge and personal experience is needed here to separate good plants from wild grass.The college students should learn to realize and remember how much of real value science has found in this wide, confused wilderness and how often scientific discoveries of what had existed in this area long age.

1. In the last paragraph the phrase "this wide, confused wilderness" refers to _____.

A．personal experience

B．wild weeds among good plants

C．the information from the parents

D．the vast store of traditional practices

2. Which of the following statements is supported by the passage?

A．The college students have trouble separating good plants from wild grass

B．Craftsman’s experience is usually unscientific

C．The contemptuous (傲慢的) college students will receive nothing from craftsmen

D．Traditional practices are as important as experience for the college students

3. The author advises the college students to ______ .

A．be contemptuous to the craftsman

B．be patient in helping the craftsman with scientific terms

C．learn the craftsman’s experience by judging it carefully

D．gain the craftsman’s experience without rejection

4. The main idea of this passage is about ________.

A．what to learn from the parents             B．how to gain knowledge

C．why to learn from craftsman               D．how to deal with experience
