2.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 62men and women aged 20to 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."

分析 本文主要介绍了一些有关荷尔蒙催生素的研究发现:荷尔蒙催生素造成了男女之间社交态度的差异;以及Ryan教授以前的与更进一步的实验结果:在消极的社会交往中,例如嫉妒时,荷尔蒙也会从我们体内释放出来;荷尔蒙催生素还能提升人们更好地区分不同社交互动的能力等.
解答 47 B 细节理解题 根据第一段"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)"可知,研究人员发现女人友好,男人更具竞争力,这一切都取决于荷尔蒙催生素;故选B
48 C 细节理解题 根据第三段"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"可知,在 Ryan 教授以前的一次试验中发现,在消极的社会交往中,例如嫉妒时,荷尔蒙也会从我们体内释放出来;故选C
49 A 细节推理题 根据最后一段Ryan教授得出的结论"Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions."可知,他实验的目的在于证实了荷尔蒙催生素能提升人们更好地区分不同社交互动的能力;故选A
50 D 内容归纳题 通读全文可知,本文主要介绍了一些有关荷尔蒙催生素的研究发现,以及Ryan教授与之相关的以前的与更进一步的实验结果;故选D
