If you want to live longer and lower the risk of heart disease, a move to the mountains may help. Research by scientists in Greece shows that living in the mountains is good for the heart and longevity(长寿). People living at higher altitude(海拔) have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk. "Residence in mountainous areas seems to have a 'protective effect' from heart disease," said Dr Nikos Baibas of the University of Athens. He and his colleagues suspect that the increased exercise from walking up mountainous area gives the heart a good workout and enables it to cope with lower levels of oxygen.

    Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years. One village was 1,000 meters above sea level and the other two were in low-lying areas. Although men and women living in the mountainous village had higher blood pressure rates and other risk factors than people in the other villages, they had a lower rate of death from heart disease and other causes after a fifteen year follow-up." The contrast was more evident among men than among women," Baibas added in a report in the Journal of Epidemiology and Community Health. Heart disease is one of the world's top killers. Smoking, high blood pressure, raised cholesterol levels, being overweight and a family history of the illness increase the possibility of developing the disease.

    Looking back on the first twenty years of my life, I feel grateful to have been so healthy and happy. I'm happy due to many key factors. They include my physical health, healthy finances and my family's happiness.

    Health comes first for me, because without health everything else is meaningless. Imagine starting a career without good health. Imagine achieving anything without good health. {#blank#}1{#/blank#}

    Good health is not enough to be happy. {#blank#}2{#/blank#} Money obviously pays for the basic necessities of life—food, housing, clothing, etc. —but it is also necessary for other reasons. Money guarantees we always get good medical treatment when we fall ill. {#blank#}3{#/blank#}

    Family is another important factor in having a happy life because it provides the love, joy, and support that everyone needs. I love my family with all my heart. I get pleasure from their pleasure. I suffer when they suffer.{#blank#}4{#/blank#}They give me advice when I have misunderstandings with my friends. More importantly, they are always there to share everything with me.

    {#blank#}5{#/blank#} As long as I stay healthy, work hard to earn enough money and share both good times and bad times with my family, I will always be the happiest girl in the world.

A. My family help me get through pressures and difficulties.

B. Clearly, good health is much more important than any other aspect of one's life.

C. Besides, we can use money to improve our life.

D. We still need money in today's society.

E. Sometimes the amount of money we have is determined by our happiness.

F. These three factors are all I need in this world.

G. Having good health and healthy finances, we can turn our attention to the happiness of our family.

    Frigatebirds seagoing fliers with a 6-foot wingspan, can stay aloft(up in the air) for weeks at a time, a new study has found.

Since the frigatebird spends most of its life at sea, its habits outside of when it reproduces on land aren't well-known-until researchers started tracking them around the Indian Ocean. What the researchers discovered is that the bird's flying ability is unbelievable.

    Ornithologist(鸟类学家) Henri Weimerskirch put satellite tage(标签) on a couple of dozen frigatebirds. When the data started to come in, he could hardly believe how high the birds flew.

    "First, we found, 'Whoa, 1,500 meters. Excellent,' " says Weimerskirch, "And after 2,000, after 3,000, after 4,000 meters-OK, at this altitude they are in freezing conditions, especially surprising for a tropical bird."

"There is no other bird flying so high relative to the sea surface," he says. "It's the only bird that is known to intentionally enter into a cloud," Weimerskirch says. And not just any cloud—a soft, white cumulus cloud(积云). Over the ocean, these clouds tend to form in places where warm air rises from the sea surface. The birds take a ride on the current of rising air, all the way up to the top of the cloud.

    Frigatebirds have to find ways to stay aloft because they can't land on the water. Since their feathers aren't waterproof, the birds would drown in short order. They feed by harassing other birds in flight until they bring whatever fish they've swallowed back into their mouth and the frigatebird takes it.

So in between meals, frigatebirds fly higher... and higher.

    In one case, for two months-continuously aloft.

    One of the tagged birds flew 40 miles without a wing-flap. Several covered more than 300 miles a day on average, and flew continuously for weeks. They are blessed with an unusual body. No bird has a larger wing surface area compared with body weight.

    If you are hungry,what do you do?Grab a piece of your favorite meal and stay quiet after that?Just like your stomach,even your mind is hungry.But it never lets you know,because you keep it busy thinking about your dream lover,favorite star and many such absurd things.So it silently began to pay careful attention to your needs and never let itself grow.When mind loosens its freedom to grow,creativity gets a full stop.

    This might be the reason why we all sometimes think “What happens next?”,“Why can't I think?”,“Why am I always given the difficult problems?”Well this is the result of our own karma（宿命）of using our brain for thinking of not-so-worthy things.

    Hunger of the mind can be actually settled through extensive reading.Now why reading and not watching TV? Because reading has been the most educative tool used by us right from the childhood.Just like that to develop other aspects of our life,we have to take help of reading.You have innumerable number of books in this world which will answer all your "How to?" questions.Once you read a book,you just don't run your eyes through the lines,but even your mind decodes（解码）it and explains it to you.The interesting part of the book is stored in your mind as a seed.

    Now this seed is unknowingly used by you in your future to develop new ideas.The same seed if used many times,can help you link and relate a lot of things,of which you would have never thought of in your wildest dreams! This is nothing lout creativity.The more the number of books you read,the more your mind will open up.Also this improves your speaking skills to a large extent and also makes a significant contribution to your vocabulary.Within no time you start speaking English or any language fluently with your friends or other people and you never seem to run out of the right words at the right time.

    As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input (输入) Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital, said, "Chinese characters enjoy both practical and aesthetic（审美的）value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    Even for a first-time visitor to China, it is impossible to ignore the popularity of Quick-Response (QR) codes. These square-shaped black-and-white symbols in WeChat or Alipay where QR codes are scanned to add new friends or make payments.

    The QR Code system originated in Japan. The engineer Masahiro Hara felt the limitation of the one-dimension barcode in use and thus developed the QR codes which could carry data horizontally and vertically. QR codes could hold much more information than barcode due to their extra dimension. In addition, QR codes have larger data capacity, smaller print—out size and higher resistance to dirt and damage, which make them widely applied in many other applications.

    Though the technology of QR codes is complicated, we can easily create our own QR codes with the help of QR code generators, many of which are available online for free. Users could enter the data they wish the QR code to display, and the generator turns it into a symbol that can be printed or displayed in electronic form. The process of creating QR codes could be really fun when we customise the design of the codes according to our specific needs. For instance, we can adjust the color, add a logo, and create social options etc. Moreover, dynamic (动态的) QR codes are also available. They are more various than standard QR codes because they allow users to edit data entered previously whereas data in standard QR codes cannot be edited once printed. Plus, don't limit your QR code to one mobile scanner. Anyone can scan your code with any reader. A lower barrier to entry makes success more likely for you and the user.

    Meanwhile, we must also recognize the vulnerability of QR codes. Due to its easy access, criminals can steal simply by replacing the QR codes with their own, routing cash into their own bank accounts. Hence, we should all become more conscious towards virtual money transactions through QR codes and participate in additional security measures.
