The morning had been a disaster.My tooth was aching,and I’d been in an argument with a friend.Her words still hurt：“The trouble with you is that you won’t put yourself in my place.Can’t you see things from my point of view?”Ishook my head stubbomly—and felt the ache in my tooth.I’d thought I could hold out till my dentist came back from holiday,but the pain was really unbearable.I started calling the dentists in the phone book,but no one coule see me immediatcly.Finally,at about lunchtime,I got lucky.
“If you come by right now,”the receptionist said,“the dentist will fit you in .”
I look my purse and keys and rushed to my car.But suddenly I began to doubt about the dentist.What kind of dentist would be so eager to treat someone at such short notice?Why wasn’t he as busy as the others?
In the dentist’s office,I sat down and looked around.I saw nothing but the bare walls and I became even more worried.The assistant noticed my nervousness and placed her warm hand over my ice-cold one.
When I tole her my fears,she laughed and said ,“Don’t worry.The dentist is very good.”
“How long do I have to wait for him?”I asked impatiently.
“Come on ,he is coming.Just lie down and relax.And enjoy the artwork,”the assistant said.
“The artwork?”Iwas puzzled.
The chair went back,suddenly I smiled.There was a beautiful picture,right where I could enjoy it ：on the ceiling.How considerate the dentist was ！At that moment,I began to understand what my friend meant by her words.
What a relief！

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."
