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 through 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."What causes men and women to behave differently according to the text?

When I met him, I had a lot of anger inside of me. I’ve lived my whole life in Spanish Harlem, but in my neighborhood, there are shoot-ups all the time. I know kids who have been shot or beaten up. I have friends who ended up in prison. I could have ended up that way, too, but
Mr. Clark wouldn’t let that happen.
Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact, the scores of our whole class rose. One day, he took our class to see The Phantom of the Opera, and it was the first time some kids had ever been out of Harlem. Before the show, he treated us to dinner at a restaurant and taught us not to talk with our mouths full. We did not want to let him down.
Mr. Clark was selected as Disney’s 2000 Teacher of the Year. He said he would draw three names out of a hat; those students would go with him to Los Angeles to get the award. But when the time came to draw names, Mr. Clark said, “You’re all going.”
On graduation day, there were a lot of tears. We didn’t want his class to end. In 2001, he moved to Atlanta, but he always kept in touch. He started giving lectures about education, and wrote a bestselling book based on his classroom rules, The Essential 55. In 2003,
Mr. Clark took some of us on a trip to South Africa to deliver school supplies and visit orphanages(孤儿院). It was the most amazing experience of my life. It’s now my dream to one day start a group of women’s clubs, helping people from all backgrounds.

I began working in journalism(新闻工作)when I was eight. It was my mother’s idea. She wanted me to “make something” of myself, and decided I had better start young if I was to have any chance of keeping up with the competition.
With my load of magazines I headed toward Belleville Avenue. The crowds were there. There were two gas stations on the corner of Belleville and Union. For several hours I made myself highly visible, making sure everyone could see me and the heavy black letters on the bag that said THE SATURDAY EVENING POST. When it was suppertime, I walked back home.
“ How many did you sell, my boy?” my mother asked.
“ None.”
“ Where did you go?”
“ The corner of Belleville and Union Avenues.”
“ What did you do?”
“ Stood on the corner waiting for somebody to buy a Saturday Evening Post.”
“ You just stood there?”
“ Didn’t sell a single one.”
“ My God, Russell!”
Uncle Allen put in, “ Well, I’ve decided to take the Post.” I handed him a copy and he paid me a nickle(五分镍币). It was the first nickle I earned.
Afterwards my mother taught me how to be a salesman. I would have to ring doorbells, address adults with self-confidence(自信), and persuade them by saying that no one, no matter how poor, could afford to be without the Saturday Evening Post in the home.
One day, I told my mother I’d changed my mind. I didn’t want to make a success in the magazine business.
“ If you think you can change your mind like this,” she replied, “ you’ll become a good-for-nothing.” She insisted that, as soon as school was over, I should start ringing doorbells, selling magazines. Whenever I said no, she would scold me.
My mother and I had fought this battle almost as long as I could remember. My mother, dissatisfied with my father’s plain workman’s life, determined that I would not grow up like him and his people. But never did she expect that, forty years later, such a successful journalist as me would go back to her husband’s people for true life and love.

If you were to walk up to Arthur Bonner and say, “ Hey, Butterfly Man,” his face would break into a smile. The title suits him. And he loves it.
Arthur Bonner works with the Palos Verdes blue butterfly(蝴蝶), once thought to have died out. Today the butterfly is coming back — thanks to him. But years ago if you’d told him this was what he’d be doing someday, he would have laughed, “ You’re crazy.” As a boy, he used to be “ a little tough guy on the streets”. At age thirteen, he was caught by police for stealing. At eighteen, he landed in prison for shooting a man..
“ I knew it had hurt my mom,” Bonner said after he got out of prison. “ So I told myself I would not put my mom through that pain again.”
One day he met Professor Mattoni, who was working to rebuild the habitat(栖息地) for an endangered butterfly called El Segundo blue.
“ I saw the sign ‘ Butterfly Habitat’ and asked, ‘ How can you have a habitat when the butterflies can just fly away?’” Bonner recalls. “ Dr. Mattoni laughed and handed me a magnifying glass(放大镜) , ‘Look at the leaves.’ I could see all these caterpillars(蝴蝶的幼虫) on the plant. Dr Mattoni explained, ‘ Without the plant, there are no butterflies.’”
Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly that needed help. That was how he met the Palos Verdes blue. Since then he’s been working for four years to help bring the butterfly back. He grows astragalus, the only plant the butterfly eats. He collects butterflies and brings them into a lab to lay eggs. Then he puts new butterflies into the habitat.
The butterfly’s population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonner, he earned something more: he turned his life around.
For six years now Bonner has kept his promise to stay out of prison. While he’s bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.

Some people bring out the best in you in a way that you might never have fully realized on your own. My mom was one of those people.
My father died when I was nine months old, making my mom a single mother at the age of eighteen. While I was growing up, we lived a very hard life. We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, “Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it.”
At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mother spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again if I wanted to badly enough. She drove that message so deep into my heart that I finally believed her. A year later I returned to school-walking on my own!
When the Great Depression(大萧条)hit, my mom lost her job. Then I left school to support the both of us. At that moment, I was determined never to be poor again.
Over the years, I experienced various levels of business success. But the real turning point occurred on a vacation I took with my wife and five kids in 1951.I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra$2 for each child. That was too expensive for the average American family. I told my wife that I was going to open a motel (汽车旅馆)for families that would never charge extra for children. There were plenty of doubters at that time.
Not surprisingly, mom was one of my strongest supporters. She worked behind the desk and even designed the room style. As in any business, we experienced a lot of challenges. But with my mother’s words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the word-Holiday Inn. In 1979 my company had 1,759 inns in more than fifty countries with an in income of $ 1 billion a year.
You may not have started out life in the best situations. But if you can find a task in life worth working for and believe in yourself, nothing can stop you.

Lying in the sun on a rock, the cougar （美洲狮） saw Jeb and his son, Tom, before they saw it. Jeb put his bag down quickly and pulled his jacket open with both hands, making himself look big to the cougar. It worked. The cougar hesitated, ready to attack Jeb, but ready to forget the whole thing, too.
Jeb let go of his jacket, grasped Tom and held him across his body, making a cross. Now the cougar’s enemy looked even bigger, and it rose up, ready to move away, but unfortunately Tom got scared and struggled free of Jeb.
“Tom, no!” shouted his father.
But Tom broke and ran and that’s the last thing you do with a cougar. The second Tom broke free, Jeb threw himself on the cougar, just as it jumped from the rock. They hit each other in mid-air and both fell. The cougar was on Jeb in a flash, forgetting about Tom, which was what Jeb wanted.
Cougars are not as big as most people think and a determined man stands a chance, even with just his fists. As the cougar’s claws（爪子）got into his left shoulder, Jeb swung his fist at its eyes and hit, hard. The animal howled（吼叫）and put its head back. Jeb followed up with his other fist. Then out of the comer of his eye, Jeb saw Tom. The boy was running back to help his father.
“Knife, Tom,” shouted Jeb.
The boy ran to his father’s bag, while Jeb started shouting as well as hitting, to keep the cougar’s attention away from Tom. Tom got the knife and ran over to Jeb. The cougar was moving its head in and out, trying to find a way through the wall Jeb was making out of his arms. Tom swung with the knife, into the cougar’s back.
