How to Survive Exam Stress

    Exam time is one of the most stressful in school, whether it is high school, college or graduate school. Even the best students feel the pressure. The first sign of a problem while preparing for an exam is worry{#blank#}1{#/blank#} If we can get rid of worries, or at least control them, then we're in a much better position to do well on our tests. Take the following steps to survive exam stress and increase your overall performance as a result.

    {#blank#}2{#/blank#}What causes you anxiety when you are studying? Too much noise? Then move to a quieter place. Delayed work? Catch up with your studies a couple nights before. That way you can save the final night before the exam to review and get a good night of sleep.

    The second way to deal with worry is to displace thoughts. Suppose you wake up at three in the morning and you're worried about an exam. What do you do?{#blank#}3{#/blank#} Doing something productive might allow you to sleep better when you finally do go back to bed.

    Another way to displace negative thoughts is to do something physically active. Work out. Take a quick walk or a nice run{#blank#}4{#/blank#}For example, I might worry about the exam having surprise questions that I'm not prepared to answer. But I can shove those thoughts aside by reminding myself that I've taken many exams and I've handled surprise questions before.

    The third option is to treat the symptoms. Keep things in perspective. Think of one final exam that causes you the most anxiety. Now think of the worst thing that could happen. If you've prepared, then likely the worst grade you could get is a C. And, if you've been applying what we've been talking about, then you'll likely to do no worse than a B. {#blank#}5{#/blank#}

A. How bad is that really?

B. The first is to delete the causes.

C. Another idea is to think positive thoughts.

D. Worry robs us of energy, focus and motivation.

E. How about getting up and studying for an hour?

F. What we should do is to think positively and get rid of it.

G. So just face the result bravely and make an effort to improve your grade.

    Street art is a very popular form of art that is spreading quickly all over the world. You can find it on building, sidewalks, street sings and trash cans from Tokyo to Paris, and from Moscow to Cape Town. Street art has become a global culture and even art museums and galleries are collecting the works of street artists. Even advertising companies also use street art in their ads due to its popularity.

    Street art started out very secretly because it's illegal to paint on public and private property without permission. People often have different opinions about street art. Some people think it is a crime with others think it's a new form of culture.

    Art experts claim that the movement began in New York in the 1960s. Young adults sprayed words and images on walls and trains. This colorful and energetic style of writing became known as graffiti(涂鸦). Graffiti art showed that young people wanted to rebel against society. They didn't want to accept rules, and they travelled around cities to create paintings that everyone could see. In many cases, they had trouble with the police and the local government.

    Many street corners in Paris show the works of Space Invader. A French artist uses small pieces of glass to make images of space creatures. He has been doing this for some years and the police have arrested him a few times. On his website, you can see many other places where he has created this form of art.

    Street artists do their work for some reasons. Some of them do not like the artists who make so much money in galleries and museums. They choose street art because it is closer to common people. Some artists try to express their political opinion in their works. They often want to protest against big firms and corporations. Others like to do things that are forbidden and hope they don't get caught.

    In today's world, the Internet has a big influence on street art. Artists can show their pictures to people all over the world. Many city residents, however, say that seeing a picture on the Internet is never as good as seeing it alive. The street art movement lives with the energy and life of a big city. There it will continue to change and grow.

    Elizabeth Blackwell was born in England in 1821, and moved to New York City when she was ten years old. One day she decided that she wanted to become a doctor. Thai was nearly impossible for n woman in the middle of the nineteenth century. After writing many tellers asking for admission (录取) to medical schools, she was finally accepted by a doctor in Philadelphia. She was so determined that she taught school and gave music lessons to get money for the cost of schooling.

    In 1849, after graduation from medical school. She decided to further her education in Paris. She wanted to be a surgeon (外科医生), but a serious eye problem forced her to give up the idea.

    Upon returning to the United States, she found it difficult to start her own practice because she was a woman. By 1857 Elizabeth and her sister, also n doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides being the first woman physician and founding her own hospital, she also set up the first medical school for women.

    Over the years, Brian Wansink, director of the Food and Brand Lab at Cornell University, has studied such things as how far Americans typically drive to buy food, how many times we refill our plates at all-you-can-eat buffets and how we organize our kitchens. In the mid-2000s he famously coined the phrase "mindless eating"(and wrote a book by that name) to focus attention on all the bad dietary decisions we make without really thinking about them.

    His new book, Slim by Design: Mindless Eating Solutions for Everyday Life, aims to change the design of restaurants, school lunchrooms, office cafeterias and homes so that the mindless choices we make will be more healthful ones. Some examples:

    Keep kitchen counters clear. No visible snack food, no bread, no nuts — not even breakfast cereal. In Wansink's research, "women who had even one box of breakfast cereal that was visible — anywhere in their kitchen — weighed 21 pounds more than their neighbor who didn't."

    Trick yourself into drinking less wine. "We tend to focus on the height of what we pour and not the width, so we pour 12 percent less wine into taller wineglasses than we pour into wider wineglasses." And the shape of the glass is not the only variable that affects how much we drink. Wansink writes: "Because red wine is easier to see than white wine, we pour 9 percent less red wine whenever we pour a glass."

    Wansink said his researchers also found that people ate less at restaurants when sat in well-lighted areas near windows and doors, than in darker areas or in the back. They ate less if they were offered a doggie bag, or to-go box, before they got their meals: apparently the idea of getting a "free" second meal outweighed the impulse (冲动) to clean their plates. Workers who frequently ate at their desks weighed 15.4 pounds less, on average, than those who didn't. Fruits and vegetables kept on the top shelf of the refrigerator were eaten at higher rates than those on lower shelves.

    The point, Wansink says, is to consider findings like those and change your environment or habits. Then you won't have to think about it: You'll just eat less.

    An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (迁徙).

    Migratory birds (候鸟) flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. "In English-language Wikipedia (维基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States," said the lead author John Mittermeier.

    And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.

    This finding suggests new ways to monitor changes in the world's biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.

    Mittermeier is encouraged by the search results. He commented, "I think there's a concern among conservationists (生态环境保护者) that people are losing touch with the natural world and that they're not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people's Wikipedia interest closely related to changes in nature."

    Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, "By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help."

    Janus, the Roman god, has two faces looking in opposite directions. So does artificial intelligence (AI). On one side are the positive changes, enabling people to achieve more, far more quickly, by using technology to improve their existing skills. Look the other way, though, and there are plenty of potential pitfalls.

    Like Janus, technological change may also cause disruption(混乱), but AI is likely to have a bigger impact than anything since the appearance of computers, and its consequences could be far more disruptive.

    In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although CEOs publicly praise the broad benefits AI will bring, their main interest lies in cutting costs. One European bank asked Infosys to find a way of reducing the staff in its operations department from 50,000 to 500. The McKinsey Global Institute estimates that by 2030 up to 375m people, or 14% of the global workforce, could have their jobs replaced by AI.

    A second important question is how to protect privacy as AI spreads. The internet has already made it possible to track people's digital behavior in minute detail. AI will offer even better tools for businesses to monitor consumers and employees, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised service or promotions. But AI is bound to bring invasion of privacy that is seen as unacceptable. For example, law-enforcement officials around the world will use AI to spot criminals, but may also monitor ordinary citizens.

    The third question is about the effect of AI on competition in business. A technology company that achieves a major breakthrough in artificial intelligence could race ahead of rivals, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.

    It is too early to tell whether the positive changes brought by AI will outweigh the risk. But it will put an end to traditional ways of doing things and start a new era for business and for the world at large.
