Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country. The most popular free time activity in Britain is going for a walk. And when joggers (慢跑者) jog, they don’t run the streets. Every one of them automatically heads to the park or the river. It is my firm belief that not only do we all need nature, but we all seek nature, whether we know we are doing so or not.
But despite this, our children are growing up nature-deprived (丧失). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.
The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD (多动症). Those whose housing had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
A study in Sweden indicated that kindergarten children who could play in a natural environment had less illness and greater physical ability than children used only to a normal playground. A US study suggested that when a school gave children access to a natural environment, the entire school would do better in studies.
Another study found that children play differently in a natural environment. In playgrounds, children create a hierarchy (等级) based on physical abilities, with the tough ones taking the lead. But when a grassy area was planted with bushes, the children got much more into fantasy play, and the social hierarchy was now based on imagination and creativity.
Most bullying (恃强凌弱) is found in schools where there is a tarmac (柏油碎石) playground; the least bullying is in a natural area that the children are encouraged to explore. This reminds me unpleasantly of Sunnyhill School, with its hard tarmac, where I used to hang about in corners dreaming about wildlife.
But children are frequently discouraged from involvement with natural spaces, for health and safety reasons, for fear that they might get dirty or that they might cause damage. So, instead, the damage is done to the children themselves: not to their bodies but to their souls.
One of the great problems of modern childhood is ADHD, now increasingly and expensively treated with drugs. Yet one study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.
The life of old people is much better when they have access to nature. The most important for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality.
In wider and more difficult areas of life, there is evidence to indicate that natural surroundings improve all kinds of things. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
Dr William Bird, researcher from the Royal Society for the Protection of Birds, states in his study, “A natural environment can reduce violent behaviour because its process helps reduce anger and behavior that people might regret later.” Wild places need encouraging for this reason, no matter how small their contribution.
We tend to think human beings are doing nature some kind of favor when we are protecting nature. The error here is far too deep: not only do humans need nature for themselves, but the very idea that humanity and the natural world are separable things is damaging.
Human beings are a species of animals. For seven million years we lived on the planet as part of nature. So we miss the natural world and long for contact with non-human life. Anyone who has patted a dog, stroked a cat, sat under a tree with a glass of beer, given or received a bunch of flowers or chosen to walk through the park on a nice day, understands that.
We need the wild world. It is necessary to our well-being, our health, our happiness. Without other living things around us we are less than human.

　　Every living thing has a physical boundary(分界线) that separated it from its external environment. Beginning with the bacteria and the simple cell and ending with man, every organism has a certain limit which marks where it begins and ends.

　　Anyone who has had experience with dogs, particularly in the countryside such as on farms, is familiar with the way in which the dog handles space. In the first place, the dog knows the limits of his aster's yard and will defend it against encroachment. There are also certain places where he steeps: a spot next to the fireplace, a spot in the kitchen, or one in the dinning room if he is allowed there. In short a dog has fixed points to which he returns time after time depending upon the occasion. One can also observe that the dog creates zone he is in, a trespasser(非法进入者) can cause different behaviours when he crosses the invisible lines which are meaningful to the dog.

　　This is particularly noticeable in females with pup-pies. A mother who has a new litter(一胎所生的小动物) in a little-used barn wall claim the barn as her territory. When the door opens she may make a slight movement or stir in one corner. Nothing else may happen as the intruder moves ten or fifteen feet into the barn. Then the dog may raise her head or get up circle about and lie down as another visible boundary is crossed. One can tell about where the line is by withdrawing and watching when her head goes down. As additional lines are crossed, there will be other signals, a thumping(重击) of the tail, a low moan or a growl. One can also observe comparable behavior in other vertebrates(脊椎动物)－fish, birds and mammals.

1．A dog on a farm knows ________.

[　　]

A．the size of its master's yard

B．the only fixed place where it should sleep

C．it should not sleep in the kitchen

2．A female dog with puppies will probably ________.

[　　]

A．attack any stranger who comes near

B．signal differently according to different occasions

C．raise her head at the sight of a stranger

D．growl when a stranger leaves her territory

3．It can be inferred from the third paragraph that mother dogs ________.

[　　]

A．have a sense of gradual territory

B．protect their babies cautiously

C．are ready to attack strangers

D．prefer to raise babies in barns

4．In the second paragraph, the underlined word “encroachment” probably means ________.

[　　]

5．Which of the following is FALSE according to the passage?

[　　]

A．Dogs sleep at certain places in the yard or house.

B．logs will respond to territory trespasser.

C．The boundary lines are visible and meaningful to dogs.
