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 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."

It’s puzzling, isn’t it? No matter where you try to tickle（使人发痒）yourself, even on the soles（脚底） of your feet or under your arms, you just can’t.
To understand why, you need to know more about how your brain works. One of its main tasks is to try to make good guesses about what’s going to happen next. While you’re busy getting on with your life, walking downstairs or eating your breakfast, parts of your brain are always trying to predict the future.
Remember when you first learned how to ride a bicycle? At first, it took a lot of concentration to keep the handlebars steady and push the pedals（踏板）. But after a while, cycling became easy. Now you’re not aware of the movements you make to keep the bike going. From experience, your brain knows exactly what to expect so your body rides the bike automatically. Your brain is predicting all the movements you need to make.
You only have to think consciously about cycling if something changes---like if there’s a strong wind or you get a flat tyre. When something unexpected happens like this, your brain is forced to change its predictions about what will happen next. If it does its job well, you’ll adjust to the strong wind, leaning your body so you don’t fall.
Why is it so important for our brains to predict what will happen next? It helps us make fewer mistakes and can even save our lives. For example, when a chief fireman sees a fire, he immediately makes decisions about how best to position his men. His past experiences help him foresee what might happen and choose the best plan for fighting the fire. His brain can instantly predict how different plans would work out, and he can rule out any bad or dangerous plans without putting his men at risk in real life.
So how does all this answer your question about tickling? Because your brain is always predicting your own actions, and how your body will feel as a result, you cannot tickle yourself. Other people can tickle you because they can surprise you. You can’t predict what their tickling actions will be.
【小题1】What is the best title for this passage?
| A．How Does the Brain work? |
| B．Why Can’t I Tickle Myself? |
| C．The importance of Prediction |
| D．The Importance of Our Brains |
| A．walk down the stairs |
| B．eat our breakfast |
| C．suddenly lose our balance and fall |
| D．ride a bike |
| A．decide that something is not suitable | B．think about |
| C．act according to the rules | D．expect |
| A．a scientific report for experts |
| B．a textbook for medical students |
| C．a book for children |
| D．a research paper for doctors |

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pet in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
【小题1】. The word shelter in paragraph one means:
| A．warm clothes | B．a hiding place |
| C．proper temperature | D．diet food |
| A．They are often forgotten by their owners. |
| B．They like to stay in warm places. |
| C．They build their own shelters. |

For most city people, the elevator is an unremarkable machine that inspires none of the enthusiasm or interest that Americans afford trains, jets，and even bicycles. Dr. Christopher Wilk is a member of a small group of elevator experts who consider this a misunderstanding. Without the elevator, they point out, there could be no downtown skyscrapers or tall buildings, and city life as we know it would be impossible. In that sense, they argue，the elevator’s role in American history has been no less significant than that of cars. In fact, according to Wilk? the car and the elevator have been locked in a “secret war” for over a century, with cars making it possible for people to spread horizontally (水平地)，and elevators pushing them toward life in close groups of towering vertical (垂直的)columns.
If we tend to ignore the significance of elevators, it might be because riding in them tends to be such a brief, boring, and even awkward experience^one that can involve unexpectedly meeting people with whom we have nothing in common, and an unpleasant awareness of the fact that we’re hanging from a cable in a long passage.
In a new book, Lifted, German journalist and cultural studies professor Andreas Bernard directed all his attention to this experience, studying the origins of elevator and its relationship to humankind and finding that riding in an elevator has never been a totally comfortable experience. “After 150 years, we are still not used to it”， Bernard said. “We still have not exactly learned to cope with the mixture of closeness and displeasure.” That mixture, according to Bernard, sets the elevator ride apart from just about every other situation we find ourselves in as we go about our lives.
Today，as the world’s urban population explodes，and cities become more crowded, taller, and more crowded, America’s total number of elevators—900,000 at last count, according to Elevator World magazine’s “2012 Vertical Transportation Industry”一are a force that’s becoming more important than ever. And for the people who really, really love them, it seems like high time that we looked seriously at just what kind of force they are.
【小题1】What does the underlined word “this” in Paragraph 1 refer to?
| A．The general view of elevators. |
| B．The particular interests of experts. |
| C．The desire for a remarkable machine. |
| D．The enthusiasm for transport vehicles. |
| A．to contrast their functions with elevators, |
| B．to emphasize the importance of elevators |
| C．to reveal their secret war against elevators |
| D．to explain people’s preference for elevators |
| A．Vertical direction. |
| B．Lack of excitement. |
| C．Little physical space. |
| D．Uncomfortable conditions. |
| A．the exact number of elevator lovers |
| B．the serious future situation of elevators |
| C．the role of elevators in city development |
| D．the relationship between cars and elevators |

I grew up with a fat dad—450 pounds at his heaviest.Every week he would try a new diet，and my family ended up eating whatever strange food he was trying at that moment.
After my thirdgrade year，my dad landed a lifechanging job in Manhattan.My mom，my little sister and I had to move away from our hometown，Chicago，and leave my grandmother and her beautiful food behind.
Leaving my grandmother was far more frightening than the move to New York City.There would be no more special weekends at my grandmother’s house，the only place I can remember feeling happy，safe and nourished (有营养的)．It was what I desired.In this new city，I felt extremely alone and lost，and I missed my grandmother terribly.
My grandmother knew just how I felt—And she knew the cure.Every week，she would send me a card with a $20 bill，a recipe and a list of what to buy at the market.It kept us bonded，and her recipes filled my body and soul.
Over the years，I have grown to better understand my father’s struggles with weight and the toll (代价) it took on him and those who love him.I have come to realize he was driven not by vanity (自负) or selfishness as much as by a deep pain.And in spite of growing up in such an unhealthy eating environment (or perhaps because of it)，as an adult I found a passion and a career as a nutrition consultant.
Today，my father weighs 220 pounds and is a vegan (素食者)．How he got there is a story I hope to share in the coming weeks.More importantly，food is no longer a barrier that keeps us apart，but a bridge that keep us connected.There is nothing my dad enjoys more than talking with me about dietary theories and his weightloss victories.And now I am the one regularly sending recipe cards to my father’s house，just as my grandmother did for me.

Multitasking
What is the first thing you nitice when you walk into a shop? The products displayed (展示) at the entrance? Or the soft background music?
But have you ever notice the smell? Unless it is bad, the answer is likely to be no. But while a shop’s scent may not be outstanding compared with sightsand sounds, it is certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.
A brand store has become famous for its distinctive scent which floats through the fairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that when it first introduced scent into its stores, customers’ intension to purchase increased by 80 percent.
When it comes to the best shopping streets in Pairs, scent is just as important to a brand’s success as the quality of its window displays and goods on slaes. That is mainly because shopping is a very different experience to what it used to be.
Some years ago,the focus for brand name shopping was on a few people with sales assistants’ disproving attitude and don’t-touch-what-you-can’t-afford displays. Now the rise of electronic commerce (e-commerce) has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar stores (实体店) can offer a full experience from the minute customers step through the door to the moment they leave. Another brand store seeks to be much more than a shop, but rather a destination. And scent is just one way to achieve this.
Now a famous store uses complex man-made smell to make sure that the soft scent of baby powder floats through the kid department, and coconut (椰子) scent in the swimsuit section. A department store has even opened a new lab, inviting customers on a journey into the store’s windows to smell books, pots and drawers, in search of their perfect scent.
【小题1】According to the passage, what is an increasingly powerful tool in the success of some brand store?
| A．Friendly assistant. | B．Unique scents. |
| C．Soft background music | D．attractive window display. |
| A．ashow the advantages of brick-and-mortar stores |
| B．urge shop assistants to change their attitude |
| C．push stores to use sights and sounds |
| D．introduce the rise of e-commerce |
| A．a platform that exhibts goods |
| B．a spot where travelers like to stay |
| C．a place where customers love to go |
| D．a target that a store expects to meet |
| A．compare and evaluate | B．examine and assess |
| C．argue and discuss | D．inform and explain |

Some students get so nervous before a test; they do poorly even if they know the material. Sian Beilock has studied these highly anxious testtakers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry，it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher，Gerardo Ramirez，have developed a possible solution. Just before an exam，highly anxious testtakers spend ten minutes writing about their worries about the test.
Sian Beilock: “What we think happens is when students put it down on paper，they think about the worst that could happen and they reappraise the situation. They might realize it's not as bad as they might think it was before and，in essence(本质上)，it prevents these thoughts from popping up when they're actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of B＋，compared to a B－ for those who did not.
Sian Beilock: “What we showed is that for students who are highly testanxious，who'd done our writing intervention(排解)，all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don't normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.
【小题1】Which of the following is TRUE?
| A．The result in the math test agrees with that in the biology test. |
| B．In the first math test, students who sat quietly performed better. |
| C．In the second math test, students who wrote about their feelings did worse. |
| D．Some college students are highly anxious testtakers while others are not in the tests. |
| A．Test anxiety is sure to cause students to fail the test. |
| B．Test anxiety can improve students' performance to some degree. |
| C．Students' attention and memory resources run out when worried. |
| D．Students may not be admitted into their favorite college if worried. |
| A．proper amount of burden may turn out to be a good thing |
| B．facing the fears bravely may help one to achieve more |
| C．avoiding facing the problem may contribute to relaxation |
| D．taking no action before difficulty may result in success |
| A．It is important for students to overcome test anxiety. |
| B．Anxious students overcome test anxiety by writing down fears. |
| C．It is a common practice for students being worried before a test. |
| D．Being worried before tests does harm to students' performance. |

In December 2008, Caroline Kennedy — daughter of the late U.S. President John F. Kennedy—sat down, as a frontrunner for the Senate seat in New York, for a televised interview that helped decide the future of her campaign. The result was a disaster.
Her performance wasn’t well received, in part because her speech was full of filler words—“ums,” “ahs” and “you knows.” One listener counted 27 “ums” and 38 “you knows” in the space of five minutes. A few weeks after the interview, Kennedy ended her Senate campaign.
Filler words may seem natural in everyday speech, but they can be deadly in formal presentations. “Using excessive fillers is the most annoying speech habit,” said Susan Ward, a speech specialist. “They take your listener’s attention away often to the point that he doesn’t hear anything you say. Your message is entirely lost.”
Many speakers are afraid of pause. They believe their audience will think they are inarticulate (不善于表达) if they pause to think of what to say next, so they use filler words to avoid the silence. However, a pause is actually more impressive than a filler word. Listeners know that the speaker is thinking, trying to find the right word. Sometimes a pause can actually improve a speech, as when an actor uses a dramatic pause to hold the attention of his audience. A speaker shouldn’t be afraid to pause occasionally during a speech; it shows self-confidence.
It takes some work to cut out filler words. You can begin by taking a few seconds to think about what you want to say the next time you are asked a question. This pause will help you begin powerfully, and it will help you avoid using a filler word.
The same public speaking technique applies when you are shifting from one idea to another. While you may be tempted to fill the silence between ideas with a filler word, remember to allow yourself to pause and think about what you want to say next.
If you need help overcoming your “um” problem, consider asking a family member or a friend to point out when you use filler words. You also could record an upcoming presentation and then watch yourself in action. You may be amazed at how often you say “um” or “uh”!
Although we live in a fast-paced society that seemingly demands instant answers, we must use the pause to our advantage. Finally, we should only speak when we are ready.
【小题1】In the first two paragraphs of the article the writer intends to ______.
| A．introduce Caroline Kennedy to readers |
| B．illustrate how deadly filler words can be in the public speech |
| C．explain what filler words are |
| D．remind readers that they should count filler words used in public speeches |
| A．they prevent the listener from focusing on what the speaker is saying. |
| B．they convey the speaker’s superiority to the listener. |
| C．they mean the speaker is not articulate at all. |
| D．they make the speaker appear self-confident. |
| A．give the speaker more credibility |
| B．hold the attention of the audience |
| C．show the speaker’s deep insight |
| D．help the audience relax |
| A．To have mental training in order to think faster. |
| B．To ask someone else to point out when you use filler words. |
| C．To watch a recording of your own speech. |
| D．To practice thinking for a moment before answering a question. |
