I lost my sight when I was four years old by falling off a box car in a freight (货运) yard in Atlantic City and landing on my head. Now I am thirty-two. I can slightly 1        the brightness of sunshine and what colour red is. It would be wonderful to see again,but 2        can do strange things to people.    ;

  It 3        to me the other day that I might not have come to love life as I do if I hadn’t been 4     . I believe in life now. I am not so sure that I would have believed in it so 5,otherwise. I don’t mean that I would prefer to go without my 6        I simply mean that the loss of them made me 7      the more what I had left.

  Life,I believe,asks a continuous series of 8        to reality. The more readily a person is able to make these adjustments,the more 9      his own private world becomes. The adjustment is never easy. The hardest 10      I had to learn was to believe in myself. That was 11      If I hadn’t been able to do that. I would have 12      and become a chair rocker on the front perch (门廊) for the rest of my life.

  It took me years to discover and 13        this belief. It had to start with the most elementary things. Once a man gave me an indoor baseball. I thought he was 14        at me  and I was hurt. “I can’t use this ,” I said. “  15 it with you”’ he urged me ,“and roll it around. ” The words stuck in my head. “Roll it around!” By rolling the ball I could hear 16      it went. This gave me an idea on how to achieve a goal I had thought 17      : playing baseball. At Philadelphia’s Over brook School for the Blind I invented a successful variation of 18      We called it ground ball.

  All my life I have set ahead of me a series of goals and then tried to reach them,one at a time. I had to learn my 19      It was no good to try for something I knew at the start which was wildly out of reach because that only invited the bitterness of 20      I would fail sometimes anyway but on average I made progress.

  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 behaviour. 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 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 behaviour differences between men and women are caused by biological factors (因素) that are mainly hormonal. ”
