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 （环境） in the course of common after-school 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 mid-winter．
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．
【小题1】It can be inferred from the first two paragraphs that____．

When nature is left alone, a balance is reached among the animals and plants living in one area. But when man starts his work in nature, the balance is likely to be destroyed. He grows a crop and takes it away to eat; then there are no dead leaves to fall on the ground, holding water while it sinks into the surface, or decaying (腐烂) and adding humus (腐殖质) to the soil. Unless a farmer acts with knowledge and skill, he is therefore most likely to make the land poorer. To take the place of the useful matter in the crops that he removes, he uses some kind of fertilizer. Chemical fertilizers are of great help, but the waste products of animals and decaying remains of plants should also be put on the land. In some places, it is a habit to burn waste material lying about, but such burning destroys the useful matter in the dead plants. Although the ashes that are left are valuable when put on the land, a better practice is to bury the waste so that it decays and increases the humus in the soil.

In the past, when the world population was much lower than it is now, a man had little difficulty in ordinary times in growing the food that was needed. When a field had been used some years and had become tired, the farmer could move to another place. The tired land then slowly recovered. Gradually grasses and other plants would appear on it and its productive power would slowly return to normal through their decay. But nature, left alone, would take a long time to bring back the land to its former state; the length of time required would depend on local conditions, but it might well be ten years.

It is a bad practice to grow the same crop in a field year after year. If the crop is changed, the land will suffer less because it is treated and used in a different way. Different plants have different effects on the soil. Therefore, a change of crop will do less harm than the growing of the same crop year after year and a regular change to grass will do good to the soil. Much will therefore be gained if different crops are grown one after another, a method known as the rotation (轮作) of crops.

According to the passage, the land will become poorer________.

A. if all the dead leaves are cleared away        

B. if the humus is increased after the harvest

C. if dead leaves decay in the soil by themselves 

D. if waste plant material lying about is buried

We can learn from the passage that the tired land has gradually recovered_______.

A. when grasses and other plants appear again

B. when the treatment is given by nature alone

C. after new grasses and other plants have decayed again

D. after nature has been left alone for several months

A modern farmer can hardly move to another place as he did before because_______.

A. the productive power of a new field isn't higher than that of an old one

B. there are few free fields left for him to do farming

C. it takes a farmer more than ten years to start farming in a new field

D. there will be too many grasses in a new field to grow crops

It is most likely that the author will go on to ______ in the paragraph following the passage above.

A. introduce other methods of planting crops     

B. deal with how to prevent land getting tired

C. start another topic of how to make use of land

D. explain what the rotation of crops is      

As we all know, nature has supplied every animal except man with some covering for his body such as fur, feathers, hair, and shells as a thick hide. But man has nothing but a thin skin.
If someone were to ask you, "Why did human beings start to cover their bodies with clothes?" most would answer, "To keep themselves warm, of course."
It is only when we begin to think about it a little that we realize that clothes are worn for a great many reasons that have nothing to do with our need for warmth at all.
For example, we wear clothes to some degree in order to decorate ourselves－to make ourselves, if possible, look more dignified (尊严) or nicer.
Clothes of a special kind are often worn to show that the wearer has authority or power. The individual wearing them is treated with respect because he occupies a certain office. The judge on the Bench, for example, might look a very ordinary and unimpressive figure without his wig and gown. Clothes are an important part of ceremony, whether it is connected with belief, the law, parliament, and royalty, the fighting forces or the state. How very different the Queen's Coronation ceremony (加冕仪式) would have looked without the robes, coronets and the cloth of gold.
Sometimes, even in some modern countries people wear some article of clothing, or some jewel, because they believe that it will bring them luck or protect them from evil or illness, or because it is connected with their beliefs.
None of these reasons for wearing clothes－to decorate ourselves, to show our position in the world, for ceremonial purposes, for "luck", to give ourselves dignity and authority－have anything to do with our need for warmth.
65.From the passage we know that wearing clothes is man's basic necessity to________.
A. protect skin    B. show beauty      C. keep warm    D. bring luck
66.According to the passage, the judge wearing special clothes on the Bench________.
A. looks nicer      B. looks different        C. shows wealth         D. shows power
67.Even in modern countries, sometimes people wear certain clothes because________.
A. they believe that they will get protected from bad luck and illness
B. it has something to do with their wealth
C. they want to show their power
D. they enjoy wearing such kind of clothes
68.The author's purpose in writing this article is to tell us that clothes are worn________.
A. for ceremonial occasions B. for many other reasons besides warmth
C. to keep people impressive and nicer        D. to show people's authority or power       

 Nature has provided Shangri-la with endless natural treasures, _________the land a happy home for the local people.

  A. to make                B. making                    C. made                       D. having made

The Official Theme for the 2005 World Exposition , Aichi，Japan is “Nature’s Wisdom”.

Name: The 2005 World Exposition, Aichi, Japan

Theme: “Nature’s Wisdom”

Site: Steo City, Nagakute Town, Toyata City, in Aichi Prefecture, Japan

Period: March 25 to September 25, 2005

Projected number of visitors: 15 million

Nature has provided humanity with a means to develop into complex societies based on this very basic relationship.

A vast network of knowledge and wisdom has evolved from this basic relationship between humans and nature. Nature's wisdom，her mysteries, inspiring beauty and power，have been unlocked by minds and scientific processes. Humans have become masters of this knowledge and have developed incredible technologies to employ energy and other resources.

In an increasingly overcrowded world, it is sometimes hard to focus beyond everyday life and onto the long term effects of our technological progress. Surely then，we must be reminded of the true wisdom found in a continuous relationship with nature. After all，we are in a world seeing an increasing amount of media coverage of international debates concerned about damage to the environment. It is commonly accepted that as far as the environment is concerned，it is a time to re-think our relationship with nature before it is too late.

Model Community

Continuous development is what the Eco-communities project at Expo 2005 is all about. The Eco-communities project has been expected to reuse energy and to reduce and make use of existing waste. As well, the entire Expo 2005 site--expected to host 25 million people over a six-month period--has been designed with the conservation(保持)of nature and the local environment as the top priority(优先考虑的事).

Finding answers for today' s world must be done in the background of technology. Thus，the idea of eco-communities was developed. Yet, an understanding of the socio-historical background is just as important in today’s richly multi-cultural world of economically various states and unions. And so the "Art of Life" Expo 2005 sub-theme was expected to be a model of human participation on a global scale. Expo 2005 offers to the people of the world an opportunity to come together and discuss many global issues that face humankind. It is a place to bring together the world's talent to create a model community for the future where humans can live in harmony with nature.
