Population Change

    Why is the world's population growing？The answer is not what you might think. The reason for the explosion is not that people have been reproducing like rabbits, but that people have stopped dropping dead like flies. In 1900,people died at the average age of 30.By 2000 the average age was 65.But while increasing health was a typical feature of the 20^th century, declining birth rate could be a defining one of the 21^st.

     Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays. Furthermore, around 50% of the world's population live in regions where the figure is now below the replacement level(i.e.2.1 births per woman)and almost all developed nations are experiencing sub-replacement birth rate. You might think that developing nations would make up the loss(especially since80% of the world's people now live in such nations),but you'd be wrong, Declining birth rate is a major problem in many developing regions too, which might cause catastrophic global shortages of work force within a few decades.

     A great decline in young work force is likely to occur in China, for instance. What does it imply? First, China needs to undergo rapid economic development before a population decline hits the country. Second, if other factors such as technology remain constant, economic growth and material expectations will fall well below recent standards and this could invite trouble.

     Russia is another country with population problems that could break its economic promise. Since 1992 the number of people dying has been bigger than that of those being born by a massive 50%,Indeed official figures suggest the country has shrunk by 5% since 1993 and people in Russia live a shorter life now than those in 1961.Why is this occurring? Nobody is quite sure, but poor diet an above all long-time alcoholism have much to do with it. If current trends don't bend. Russia's population will be about the size of Yemen's by the year 2050.

     In the north of India, the population is booming due to high birth rates, but in the south, where most economic development is taking place, birth rate is falling rapidly. In a further twist, birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas. In total,25% of India's working-age population has no education. In 2030,a sixth of the country's potential work force could be totally uneducated.

    One solution is obviously to import foreign workers via immigration. As for the USA, it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010-2030,Moreover,the USA has a track record of successfully accepting immigrants. As a result it's likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.

    Have you ever felt a sudden feeling of joy because you heard a favorite song playing? Then you know that music can have a strong effect on your emotions. {#blank#}1{#/blank#} It can help get you out of a bad mood (心情) or stay in a good one, says Alicia Ann Clair, professor at the University of Kansas. {#blank#}2{#/blank#}

    To cheer up, listen to Latin music or anything with a strong beat or a fast speed{#blank#}3{#/blank#}. When you want to relax after a busy day, music with a slower speed can calm you down.     

    Listen to calming music before you start any stressful activities, advises Dr. Clair. "Once you' re in a good state of mind, it' s easier to keep it." You can lower stress at work with music, too, by playing relaxing tunes (曲调). {#blank#}4{#/blank#} "If you listen to them all day long, you'll stop noticing them," Dr. Clair explains. Then the music won't have any effect.

    {#blank#}5{#/blank#}."To feel energetic, start with something relaxing, and then gradually increase the speed and beat," says Dr. Clair. For example, first play some nice slow love songs, and then listen to something more energetic. When you want to calm down after a busy week at work, just do the opposite.

    There is a woman named Tao Porchon-Lynch. She was born in India in 1918. So, if you do the math, she's 99. And at the age of 99, she has been recognized as the oldest yoga teacher in the world. She has been teaching yoga in a gym in her hometown, full-time, since 1967.

    But that's not all she's done. She has also been a model, actress and dancer. She became a model after she graduated from high school. She acted in more than ten fields. She won a lot of medals as a dancer in many competitions. She once said, “If you try your best and never give up, nothing is impossible.” And she is a firm believer in positive thinking. She dreams the impossible dreams, and she is also well known as a thinker.

    Tao Porchon-Lynch is not the person who talks the talk; she is the person who walks the walk. When she makes up her mind to do something, she takes action to do it without delay. At the age of 85, she learned how to dance and even won several dance competitions. She offers this piece of advice to others, “Don't put off till tomorrow what you can do today. Don't delay. Tomorrow never comes.”

    So, what about retirement? At 98, she is well past the age when many people make retirement plans. Retiring, it turns out, is not Tao's style. “A little girl, who is only 6 years old and is now learning yoga with me, once asked me, ‘Dear granny, what are you going to do when you retire?'” Tao Porchon-Lynch told the little girl that she had no plans to retire but instead would continue to teach yoga and dance her way to next planet.

How to Do Man-on-the Street Interviews

    The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the spot. {#blank#}1{#/blank#} But with these tips, your first man-on-the-street interview experience can be easy.

    When your boss or professor sends you out to do man-on-the –street interviews for a story, think about the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, "Why do you think environmental protection is important in America?" {#blank#}2{#/blank#}

    Hit the streets with confidence. {#blank#}3{#/blank#} Say, "Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic," This is a quick way to get people to warm up to you.

    Move on to the next person if someone tells you she is not interested in talking on camera. Don't get discouraged.

    {#blank#}4{#/blank#} Each interview that you get on the street shouldn't be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Make sure that as you go from interview to interview, you are getting a variety of answers. If everyone is giving you the same answer, you won't be able to use it. A safe number of interviews to conduct is about six to ten. {#blank#}5{#/blank#}

    If your news station or school requires interviewees to sign release forms to appear on the air, don't leave work without them.

A. Limit your time.

B. As you approach people, be polite.

C. If you don't own a camera, you can buy one.

D. For new reporters, this can seem like a challenging task.

E. To get good and useful results, ask them the same question.

F. That number of interviews should give you all the answers you need.

G. With a question like this, you will get more than a 'Yes" or "No" reply.

Why the youth sense anger in faces

    We tend to believe that older people are more positive and younger people are more sensitive to social cues (暗示).

    Recently scientists investigated this idea by testing 10,000 men and women. They wanted to see if age affected a person's ability to identify facial emotions, such as fear and anger.

    The researchers from McLean Hospital in the US used a Web-based platform to collect happiness data. It showed the participants two headshots (头部特写)of random people. They were then asked to identify which subject was angrier, happier, or more fearful.

    The research found that younger people were able to better identify angry and fearful facial cues than older people.

    "From studies and anecdotal evidence, we know that the everyday experiences of an adolescent are different from an older person, but we wanted to understand how these experiences might be linked with differences in basic emotion understanding,wrote Laura Germine, the study's senior author.

    But what is it that makes young people more sensitive?

    "This is the exact age when young people are most sensitive to forms of negative social cues, such as bullying," Lauren Rutter, the study's lead author, told Science Daily. "The normal development of anger sensitivity can contribute to some of the challenges that arise during this phase of development.

    On the contrary  across the whole 10,000-person survey, researchers found no decline in the perception (感知)of happiness among older participants.

    "What's remarkable is that we see declines in many visual perceptual abilities as we get older, but here we did not see such declines in the perception of happiness, Germine told Neuro Science News.

    She added that these findings fit well with other researches, showing that older adults tend to have more positive emotions and a positive outlook.

    Following the paper's release, Rutter told Neuro Science News that gathering their primary research online allowed the team to research into a "much larger and more diverse sample set" than previous studies.

    In business, there is a speed difference: It's the difference between how important firm leaders say speed is to their competitive strategy and how fast the company actually moves. The difference is important regardless of industry and company size. {#blank#}1{#/blank#}

    In our study of 343 businesses, the companies that choose to go, go, go to try to gain an edge ended up with lower sales and operating incomes than those that paused at key moments to make sure they were on the right track. What's more, the firms that “slowed down to speed up “improved their top and bottom lines, averaging 40% higher sales and 52% higher operating incomes over a three-year period.

    {#blank#}2{#/blank#} They thought differently about what "slower" and "faster" mean. Firms sometimes fail to understand the difference between operation speed (moving quickly )and strategic speed (reducing the time it takes to deliver value ).Simply increasing the speed of production, for example ,may be one way to try to reduce the speed difference .But that often leads to reduced value over time, in the form of lower-quality products and services.

    In our study, higher-performing companies with strategic speed always made changes when necessary. They became more open to ideas and discussion. {#blank#}3{#/blank#} And they allowed time to look back and learn. By contrast, performance suffered at firms that moved fast all the time, paid too much attention to improving efficiency, stuck to tested methods, didn't develop team spirit among their employees, and had little time thinking about changes.

    Strategic speed serves as a kind of leadership. {#blank#}4{#/blank#} That kind of strategy must come from the top.

A. How did they disobey the laws of business physics, taking more time than competitors yet performing better?

B. Teams that regularly take time to get things right, rather than plough ahead full bore, are more successful in meeting their business goals.

C. More haste, less speed, which in the study proves wrong.

D. Companies fearful of losing their competitive advantage spend much time and money looking for ways to pick up the speed.

E. They valued efficiency rather than consideration.

F. They encouraged new ways of thinking.
