Q: Article: Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin . 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 tend to be competitive. They are trying to improve their social status," said Professor Ryan. Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction 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 received oxytocin. The other half received placebo . [( )] [( :Love my Dog.)] 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 factor that are mainly hormonal."

Q: Article: Many young people tell me that they want to be writers. I always encourage such people, but I also explain that there is a big difference between being a writer and writing. In most cases these people are dreaming of wealth and being famous, not the long hours alone at the typewriter. When I became a writer, I had no future. What I had was a friend called George. He found me a home. It was cold and had no bathroom. I could only afford a used typewriter. A year later, however, I still hadn't received a break and began to doubt myself. But I knew I wanted to write. I would keep putting my dream to the test--even though it meant living with fear of failure. This is the shadow land of hope, and anyone with a dream must learn to live there. Then one day I got a call from a friend who asked me to be an assistant for $6,000 a year. As the dollars were dancing in my head, _ brought me to my sense. "Thanks, but no," I heard myself saying. After that, I walked around my little room and started to feel like a fool. I felt a little low. Later, I gradually began to sell my articles. It was after 17 years of being a writer that Roots was published. At once I had the kind of fame and success that few writers ever experienced. The shadows had turned into great sunlight. Before that, it was a long and slow climb out of the shadows.
