People aren’t walking any more---if they can figure out a way to avoid it.

I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn’t in ay hurry, either, I had merely become one more victim of a national sickness: motorosis.

It is an illness to which I had thought myself immune(), for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day’s walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced –and beat—a teenage football player the 168 steps up the Stature of Liberty.

Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper…… is more likely to have illnesses than one who exercises regularly. And wlaking is an ideal form of exercise--- the most familiar and natural of all.

It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.

The car is a convenient means of transport, but we have made it our way of life. Many people don’t dare to approach Nature any more; to them the world they were born to enjoy is all threat. To them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.

I say that the green of forests is the mind’s best light. And none but the man on foot can evaluate what is basic and everlasting.

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.

"Women tend to be social in their behavior. They often share with others. But men lend to be competitive. They are trying to improve their social status," said Professor Ryan.

Generally, people believe that the hormone oxytocin is let out in our body in various social situations and

our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.

But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.

Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants（参与者）received oxytocin. The other half received placebo (安慰剂).

After a week, the two groups switched with participants. They went tlirough the same procedure with the other material.

Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.

The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.

Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal."

B. Our body lets out oxytocin when we are deep in love.

C. Our body produces oxytocin when we feel unhappy about others' success.

D. Oxytocin improves our abilities to understand people's behavior differences.

3.Why did Professor Ryan conduct the recent experiment?

A. To test the effect of oxytocin on the ability to recognize social interactions.

B. To know the differences between friendship and competition.

C. To know people's different abilities to answer questions.

D. To test people's understanding of body language.

More and more corporations are taking an interest in corporate social responsibility (CSR). CSR is made up of three broad layers. The most basic is traditional corporate charity work. Companies typically spend about 1% of pre-tax profits on worthy projects. But many feel that simply writing cheques to charities is no longer enough. In some companies, shareholders want to know that their money is being put to good use, and employees want to be actively involved in good works.

Money alone is not the answer when companies come under attack for their behavior. Hence the second layer of CSR, which is a branch of risk management. Starting in the 1980s, with environmental disasters such as the explosion at Bhopal and the Exxon Valdez oil spill, industry after industry has suffered blows to its reputation.

So, companies often responded by trying to manage the risks. They talk to non-governmental organisations (NGOs) and to governments, create codes of conduct（行为准则) and devote themselves to more transparency（透明）in their operations. Increasingly, too. they, along with their competitors, set common rules to spread risks.

All this is largely defensive, but there are also opportunities for those that get ahead of the game. The emphasis on opportunity is the third layer of CSR: the idea that it can help to create value. If approached in a strategic way, CSR could become part of a company's competitive advantage. That is just the sort of thing chief executives like to hear. The idea of "doing well by doing good" has become popular.

Nevertheless, the business of trying to be good is bringing difficult questions to executives. Can you measure CSR performance? Should you be cooperating with NGOs and you’re your competitors? Is there any really competitive advantage to be had from a green strategy?

Corporate social responsibility is now seen as a mainstream. Big companies want to tell the world about their good citizenship with their devotion to social responsibilities. Done badly, CSR is often just window-dressing and can be positively harmful. Done well, though, it is not some separate activity that companies do on the side, a corner of corporate life reserved for virtue（美德）：it is just good business.
