Question

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷爾蒙催生素). 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 (互動) 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（參與者）received oxytocin. The other half received placebo (安慰劑).

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."

【解析】文章大意：文章講述了Professor Ryan調(diào)查實(shí)驗(yàn)，實(shí)驗(yàn)告訴我們荷爾蒙催生素能提高人們辨認(rèn)不同的社會交往的能力；男女之間行為的差異是由主要是荷爾蒙的生物因素所引起的。

1.細(xì)節(jié)題。根據(jù)文章第一段1,2行Women are friendly. But men are more competitive. Why? Researchers have found it’s all down to the hormone oxytocin(荷爾蒙催生素)可知，男女之間行為表現(xiàn)的不同是由于荷爾蒙催生素水平的不一樣導(dǎo)致的。故B正確。

2.推理題。根據(jù)文章第三段Generally, people believe that the hormone oxytocin is let out in our body in various social situations and和our body creates a large amount of it during positive social interactions (互動) such as falling in love or giving birth.第四段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在實(shí)驗(yàn)里Professor Ryan發(fā)現(xiàn)在消極的社會交往中，我們身體也釋放出荷爾蒙，可知之前的實(shí)驗(yàn)告訴我們hormone oxytocin (荷爾蒙催生素)使用了另外一種形式來影響我們的行為。故A正確。

3.推理題。文章最后三行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."

可知，最近這次實(shí)驗(yàn)是想測試一下荷爾蒙催生素對辨認(rèn)社交能力的效果，而結(jié)果證實(shí)了荷爾蒙催生素能提高人們的這種能力。

4.推理題。作者是通過討論所做的不同的實(shí)驗(yàn)產(chǎn)生的不同的結(jié)果而展開，之前的實(shí)驗(yàn)結(jié)果和現(xiàn)在的實(shí)驗(yàn)結(jié)果的比對。產(chǎn)生新的結(jié)論。故D正確。
