  It's rare that you see the words "shyness" and "leader" in the same sentence. After all, the common viewpoint is that those outgoing and sociable guys make great public speakers and excellent networkers and that those shy people are not. A survey conducted by USA Today referred to 65 percent of executives who believed shyness to be a barrier to leadership. Interestingly, the same article stresses that roughly 40 percent of leaders actually are quite shy—they're just better at adapting themselves to situational demands. Bill Gates, Warren Buffet and Charles Schwab are just a few "innies".

  Unlike their outgoing counterparts who are more sensitive to rewards and risk-taking, shy people take a cautious approach to chance. Rather than the flashy chit-chat that defines social gathering, shy people listen attentively to what others say and absorb it before they speak. They're not thinking about what to say while the other person is still talking, but rather listening so they can learn what to say. Along the same lines, shy people share a common love of learning. They are intrinsically(内在地) motivated and therefore seek content regardless of achieving an outside standard.

  Being shy can also bring other benefits. Remember being in school and hearing the same kids contribute, until shy little Johnny, who almost never said a word, cut in? Then what happened? Everyone turned around to look with great respect at little Johnny actually talking. This is how shy people made good use of their power of presencethey "own" the moment by speaking calmly and purposefully, which translate to a positive image.

  Shyness is often related to modesty. Not to say that limelight-seekers aren't modest, but shy people tend to have an accurate sense of their abilities and achievements. As a result, they are able to acknowledge mistakes, imperfections, knowledge gaps and limitations.

  Since shy people have a lower sensitivity to outside rewards than outgoing ones, they're more comfortable working with little information and sticking to their inner desires. Shy people are also more likely to insist on finding solutions that aren't primarily apparent. Don't believe me? Maybe you'll believe Albert Einstein, who once said, "It's not that I'm so smart, it's that I stay with problems longer." Obviously, finding certainty where uncertainty is typically popular is a huge plus for any successful person.

  The myth that shy people are less effective leaders than their outgoing fellows is just a misunderstanding. Make wise use of your personality strengths to lead your business no matter what side of the range you fall on.

 The Internet is full of headlines that grab your attention with buzzwords 流行词).But often when we click through, we find the content hardly delivers and it wastes our timeWe close the page, feeling we've been cheatedThese types of headlines are called "click bait"

    A headline on Busing, reconsidercom reads:  "This phrase will make you seem more polite"First, when you click through, you find another headline: "Four words to seem more polite" Then, on reading the article, you find it's actually an essay about sympathyAnd what are the four words? They're "Wow, that sounds hard" On some video websites, you might encounter headlines such as "Here's what happens when six puppies visited a campus"Turns out it's just some uneventful dog footage镜头).

     Nowadays, with the popularity of social media, many news outlets tweet 推送 click bait links to their storiesThese tweets take advantage of the curiosity gap or attempt to draw the reader into a story using a question in the headlineThese click bait headlines are so annoying that someone is attempting to save people time by exposing news outlet click bait through social mediaThe Twitter account @SavedYouAClick, run by Jake Beckman, is one such example

     Beckman's method is to grab tweets linking to a story and rewet them with a click-saving commentFor example, CNET tweeted "So ios 8 appears to be jailbreak able but…", with a link to its coverage of Apple's product announcementsBeckman retreated it with this comment attached: "...it hasn't been jail broken yet"

   Since founding the account, Beckman's Twitter experiment has brought him more than 131,000 followersBeckman said that @SavedYouAClick is  "just my way of trying to help the Internet be less tumble" Asked about his goal, he said, "I'd love to see publishers think about the experience of their readers firstI think there's an enormous opportunity for publishers to provide readers with informative updates that include links so you can click through and read more

Sociologists have long recognized that organizations of less than 200 individuals can operate through the free flow of information among the members. Once their size goes beyond this figure, the organizations are getting less flexible. So it seems necessary to prevent total disorder resulting from failures of communication.

   One solution to this problem would, of course, be to structure large organizations into smaller units of a size that can act as a group. By allowing these groups to build reliance on each other, larger organizations can be built up. However, merely having groups of, say, 150 will never of itself be a complete solution to the problems of the organization. Something else is needed: the people involved must be able to build direct personal relationships. To allow free flow of information, they have to be able to communicate with each other in a casual way. Maintaining too formal a structure of relationships inevitably prevents the way a system works.

  The importance of this was drawn to my attention two years ago by the case of a TV station. Whether by chance or by design, it so happened that there were almost exactly 150 people in the station. The whole process worked very smoothly as an organization for many years until they were moved into purpose-built accommodation. Then, for no apparent reason, the work seemed to be more difficult to do, not to say less satisfying.

 It was some time before they work out what the problem was. It turn out that, when the architects were designing the new building, they decided that the coffee room where everyone ate their sandwiches at lunch times was an unnecessary luxury and so did away with it. And with that, they accidentally destroyed the close social networks that strengthened the whole organization. What had apparently been happening was that, as people gathered informally over their sandwiches in the coffee room, useful information was casually being exchanged.

68What size of an organization may lead to communication failures?

       AAn organization of less than 200 individuals.

       BAn organization of more than 200 individuals.

       CAn organization of less than 150 individuals.

       DAn organization of more than 150 individuals.

69We can solve the communication problem within a large organization by         .

       Aallowing free flow of information

       Bmaintaining a formal structure of relationships

       Cstructuring larger organizations into smaller units

       Dstructuring smaller organizations and building direct personal relationship

70After the TV station moved into new accommodation, its operation         .

       Aseemed to be more difficult                   Bseemed to be more satisfying

       Cseemed to be more successful               Dseemed to be more effective

71What can b e concluded from the last paragraph?

       AIt’s unwise to do away with the coffee room when designing a new office building.

       BThe coffee room is the most important place in an office building.

       CUseful information was formally being exchanged over their sandwiches in the coffee room.

       DThe coffee room where everyone ate their sandwiches at lunch times was an unnecessary luxury.

The time of year a baby is born can shape what profession they will embark on in later life, a new study has suggested. Being born in a certain month appears to indicate the possibility of what job a person will end up with, the study by the Office for National Statistics found.     

Researchers have uncovered that the month in which babies are born could also affect everything from intelligence to length of life. A child born in December is more likely to become a dentist while someone whose birthday falls in January will tend to a debt collector, they found.   

A February birth appears to increase the chances of being an artist while March babies appear to go on to become pilots. Meanwhile, April and May are said to have a fairly even spread of professions, births in the summer months mean a much lower chance of becoming a high-earning football player, doctor or dentist. The study was gained by researchers who analyzed the birth months of people in 19 separate occupations using information from the last census (人口普查), the Daily Mail reported. Although these trends may be difficult to explain, relations between birth months and specific health problems have a scientific basis.

Spring babies are at greater risk of illnesses including schizophrenia, Alzheimer’s disease, asthma and autism. They may also be less clever than classmates born in other parts of the year.

25. What does the underlined phrase “embark on” refer to?

A. land on        B. keep in touch with           C. be engaged in          D. break from

26. According to the researchers, a child born in March is likely to become_______.

A. a debt collector           B. a pilot               C. a dentist           D. an artist

27. We can learn from the text that______.

A. the month babies are born could only affect his intelligence and length of life 

B. People born in the summer months are more likely to get highly paid

C. Spring babies may have the bigger chance to get ill       

D. the choice of profession for April and May is very narrow

28. What can be included from the passage?

A. There exist connections between birth date and occupations         

B. The fate has been already decided when people are born         

C. People born in Autumn would be more successful than those born in Spring

D. The time of year one is born decides which specific health problems one has

MEXICO CITY A jetliner from the beach resort of Cancun was briefly hijacked as it landed in Mexico City on Wednesday. The hijackers released all passengers shortly before federal police stormed the plane, and the crew emerged unharmed moments later.

Police, who did not fire a single shot, led as many as eight handcuffed men away from the airplane, which was isolated at the end of a runway in an area designed for emergencies. The hijackers’ motive was unclear, though Mexican news media initially identified them as Bolivians demanding to speak with Mexican President Felipe Calderon.

US, French and Mexican citizens were among the 112 passengers and crew on Aeromexico Flight 576, according to a US official who had been briefed on the situation. The official was not authorized to discuss the case and spoke on condition of anonymity.

Mexico’s transportation and communications secretary, Juan Molinar, said there was no bomb on the airplane, although some passengers said one of the hijackers held a package that resembled an explosive device, and a bomb squad (拆弹小组) was later seen near the airplane.

He did not immediately identify the hijackers or speculate on their motive.

Various people who participated in the act have been detained and we are investigating,Molinar said.

The attorney general’s office said it was opening an investigation into terrorism and kidnapping but did not specify how many people could be charged.

Mexican news media initially reported the hijackers were Bolivian, but Bolivia’s ambassador to Mexico, Jorge Mancilla, said Mexican authorities had no evidence that was the case. Mancilla said sources told him they could be Colombian or Venezuelan. Several passengers told reporters they did not notice a non-Mexican accent.

Passenger Rocio Garcia told the Televisa network that the pilot made an announcement after landing in Mexico City that the airplane was being hijacked. Passengers said the hijackers never communicated with them directly.

These were scary moments,she said.

She said she saw one of the hijackers whom she described as a well-dressed, older man.

He looked fine, like a normal passenger,she said.

Passenger Daniel Hernandez said he saw a hijacker carrying a Bible.

1From the first paragraph we can conclude that _________.

       Athe hijackers just wanted to play a trick on the police

       Bthe hijackers didn’t prepare for their action

       Cthe hijackers surrendered before the police fired

       Dthe hijackers lost their way at the last moment

2From what Juan Molinar said we can learn that _________.

       Apolice were still trying to identify a possible bomb

       Bpassengers succeeded in stopping the explosion

       Ca frightening bomb was found later on the airplane

       Dseveral Mexicans were involved in the hijacking

3What may be the first step taken when the hijacked plane landed?

       AThey gave a sudden attack at the hijackers.

       BThey kept the plane away from other planes.

       CThey asked the crew to control the hijackers.

       DThey abandoned the plane at the end of the runway.

4The hijackers, as some passengers described, _________.

       Awere good at bargaining with the police

       Bwere all well-dressed American old men

       Call came from Colombia or Venezuela

       Dstayed calm and appeared noble, educated

 Ladies and gentlemen, please fasten your seat belts. The plane _____.

A. takes off   B. has taken off    C. took off    D. is taking off.

Have you ever fancied sailing around the world or buying a holiday home in the Caribbean? Well, before you get too excited, it may help to find out if you have what it takes to become a billionaire.

    We’ve all heard stories of school drop-outs who have made their fortune. Do they tend to be university graduates or self-made successful people? Are they married or single?

    Thanks to a recent analysis of people in Forbes (福布斯) Top 100 Billionaires List, we can now find out what they have in common. We know what percentage wear glasses and even how many are bald!

If you are deciding whether or not to go to university, it may help you to know that 76% of the richest people in the world have a degree. According to this study, of those 76%, 47% have a bachelor’s degree, 23% have a master’s and 6% have a doctorate. Don’t lose hope if you aren’t very academic, though. It’s worth noting that many of those on the list did not pass all their exams with flying colors. Microsoft founder Bill Gates dropped out of Harvard University after two years of study. And Chinese business magnate Jack Ma, failed his university entrance exams three times before going on to complete his degree and make his millions.

Another interesting trend is that the world’s richest people are much more likely to be married — only 12% of billionaires are unmarried. Finally, the percentage of billionaires who are bald is quite high — so don’t worry if you’re losing your hair.

33. What do Bill Gates and Jack Ma have in common according to the passage?

A. They have the same amount of money at present.

B. They both graduated from the same university in the U.S.A.

C. They were both born in a poor family and had much suffering while young.

D. They become very successful though they didn’t do well in their academic lives.

34. What was the purpose of the study?

A. To advise readers to sail around the world in their own yachts.

B. To tell readers when and how these people became billionaires.

C. To encourage readers to find probable ways to their own success.

D. To find similarities between the top 100 richest people in the world.

35. What may be the best title for the text?

A. Tales of Bill Gates and Jack Ma.               B. How to Become a Billionaire.

C. Forbs Top 100 Billionaires List.                D. How Bill Gates Made His Fortune.

Easy Ways to Keep Your Brain Sharp

Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.  71     Read on for some techniques worth trying.

1.  72     

People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study.    73    Something as simple as setting a goal to havea weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

2. Go for a walk.

Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain.   74     

3. Learn something new.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.   75    .

A. Focus on the future.

B. This can be especially harmful to the aged.

C. It should be something like learning gardening or go dancing with your friends.

D. So take a few minutes each day to do some reading.

E. But don't worry if your schedule isn't filled with life-changing events.

F. Luckily, research shows there is a lot you can do to avoid those moments.

G. In other words, when you take care of your body, you take care of your brain.

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease – especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.

The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap may be “well,” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.

1Today medical care is placing more stress on           .

Aremoving people's bad living habits

Bmonitoring patients’ body functions

Ckeeping people in a healthy physical condition

Densuring people’s psychological well-being

2In the first paragraph, people are reminded that           .

Aregular health checks are essential to keeping fit

Bdrinking, even if not to excess, could be harmful

Cgood health is more than not being ill

Dprevention is more difficult than cure

3Traditionally, a person is considered “well” if he            .

Adoes not have any unhealthy living habits

Bis free from any kind of disease

Cis able to handle his daily routines

Ddoes not have any physical handicaps

4According to the author, the true meaning of “wellness” is for people            .

Ato best satisfy their body's special needs

Bto meet the strictest standards of bodily health

Cto strive to maintain the best possible health

Dto keep a proper balance between work and leisure

5According to what the author suggests, which of the following groups of people would be considered healthy?             

APeople who have strong muscles as well as slim figures.

BPeople who are not presently experiencing any symptoms(症状)of disease

CPeople who can recover from illness even without seeking medical care.

       DPeople who try to be in as sound mind as possible, regardless of their physical limitations.

Dont leave matches or cigarettes on the table within ______ of children.

A. stretch  B. expand   C. reach    D. extend

 – Mary looks hot and dry.

   – So _______ you if you had a high fever.

    A. do           B. are          C. will         D. would

For most pregnant women, exercise is the last thing on their mindsAfter all, keeping slim while you’re expecting isn’t exactly the top priority rather, it’s making sure your baby gets enough nutrients to growBut in a small new study, researchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exercise may be good for a growing fetus’ health — and may even help a baby get a healthier start in life

The finding is a bit surprising, because exercise is known to lower the risk of insulin resistance(胰岛素抵抗)a condition eventually leading to diabetes(糖尿病)Although insulin resistance is a detriment in healthy adults, it turns out to be helpful for proper fetal(胎儿)developmentIn pregnant women, this condition means nutrients get shunted to the growing baby

The question is: could a mother’s exercise put her developing baby’s food supply at risk? Past studies looking at the effect of exercise on birth weight have been inconclusive, and none have really investigated the influence of exercise on the mother’s sensitivity to insulinSo the University of Auckland’s DrPaul Hoffman and his team decided to study 84 first-time mothers, who were of normal weight on average, and track any effects aerobic exercise(有氧运动) might have on their insulin sensitivity and, ultimately, on their babies’ birth weightResearchers asked some women to exercise on a stationary bicycle for at least 40 minutes per session, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exerciseWhen the two groups and their babies were compared, the team found that women who bicycled regularly gave birth to babies who were on average 150g lighter than those born to the non-exercising mothersIn both groups, however, the babies were of healthy weight, and there was no difference in the mothers’ weights

Generally speaking, babies on the lower end of the normal weight range are considered healthier and less prone to developing diabetes and obesity than heavier ones, so this was an encouraging resultEven more reassuring was that regular exercise did not seem to affect the flow of nutrients to the growing babies in the womb

1According to the new study, a pregnant woman’s regular exercise may _______

      Abring benefits to a baby’s growth

      Blower the risk of insulin resistance

      Cput her baby’s food supply at risk

      Dhelp her keep slim and healthy

2What does the underlined word “detriment” mean in the second paragraph?

      ASomething that brings good             BSomething that brings damage

      CSomething that brings obstacles       DSomething that brings development

3What is the purpose of the experiment carried out by DrPaul Hoffman?

      ATo investigate the influence of exercise on pregnant women

      BTo find out what aerobic exercise can benefit a baby’s growth

      CTo make sure of the effects exercise may have on babies’ birth weight

      DTo compare the differences between mothers who exercise and who don’t

4Which of the following statements is true according to the passage?

      ALighter babies are generally believed to be healthier than heavier ones

      BNon­exercising mothers will definitely give birth to heavier babies

      CNo studies have looked at the effect of exercise on birth weight before

      DSome women studied were asked to exercise regularly while some don’t

5Which of the following may be the best title for the passage?

      AAll mothers should take aerobic exercise

       BMoms who exercise give birth to lighter babies

      CExercise reduces the risk of insulin resistance

      DHeavier babies are more likely to develop diabetes

Does solving a math problem give you a headache? Do you feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain.

Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fear math. Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson.

Based on their answers, participants were divided into groups. One group was made up of people  who  were particularly afraid  of  math  and participants  in  the other  group were  more comfortable with the subject.

Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue square would be shown.

Using a brain-scan machine, scientists noticed that whenever people from Group One saw a yellow circle, their brain would respond in a way similar to when their body is feeling pain. It was like the pain they would fee, for example, if they burnt their hand on a hot stove. But they reacted less strongly when they knew that they would be faced with a word task.

However, scientists saw no strong brain response from people in the second group.

Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. “When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong,” explained Ian Lyons from University of Chicago, US, leader of the study. “The higher a person’s anxiety of a maths task, the more he activated brain regions associated with threat detection, and the experience of pain.”

More interestingly, the brain activity disappeared when participants actually started dealing with the math tasks. “This means that it’s not that math itself hurts; rather,  the anticipation of math is painful,” Lyons said.

Based on the study, scientists suggested that things could be done to help students worry less and move past their fear of math, which might mean they perform better in tests.
