How to Be Confident

    We are all human and have weaknesses. Even if your physical appearance or social skills aren't what you wish they were, that doesn't have to stop you from being confident. {#blank#}1{#/blank#}

    *Make a list of special talents you have, or things you do that are good—morally（道德上） or otherwise. It doesn't have to be a specific skill；it can be an approach or an attitude that you hold through life. {#blank#}2{#/blank#} Are you very patient with people? Do you always see the humorous side of things? Are you always there for your friends?

    {#blank#}3{#/blank#} When you feel strongly about something, speak loudly and clearly and make eye contact with people. People will judge you all the time, and usually they'll misjudge you anyway, so why bother trying to live up to their opinions at all?

    *Take care of yourself. Eat a healthy diet and get enough exercise. Don't abuse your body, don't overload it, and don't deny it any of the things it needs. At the same time, don't obsess(沉迷). {#blank#}4{#/blank#} Those things are only band-aids(权宜之计） and make-up. Confidence comes from within. In order to be confident, you must value yourself and understand that your well-being is important.

    *Improve your posture. {#blank#}5{#/blank#} Don't drop your shoulders. Make sure that your back is straight, your shoulders are square, and your chest sticks out slightly (but stay loose, otherwise you'll appear stubborn （固执的）and nervous). Good posture also helps with deep breathing, which helps with feeling calm and relaxed.

    Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided. {#blank#}1{#/blank#}

Write it out

    You can also check a math problem by writing everything out on paper. {#blank#}2{#/blank#} Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.

{#blank#}3{#/blank#}

    Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.

Plugging in

    You may find that a variable isn't good enough or have a problem where you have to solve for a variable (变量). {#blank#}4{#/blank#} This is the only real way to assure yourself that the answer you've found is correct.

Check for a reasonable answer

    {#blank#}5{#/blank#} For example, if you get an answer in the millions and you know it should be in the thousands, you've likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you've got on the first try.

    Most Americans are worried about new technology. They are concerned that machines, including robots, will take over work now done by humans. These findings come from a new report by the Pew Research Center of Washington D. C.

    About 75 percent of Americans questioned by Pew said automation will increase income inequality between the rich and the middle class and poor. And 64 percent of people expect automation to be so common in America that people will face difficulty finding things to do with their lives.

    Some of the concerns about technology come from a distrust about whether machines will always make the right decision. Many Americans believe humans have better judgement in dealing with. complex matters. One example is selecting a person for a job. Three-quarters of Americans said they would not want to apply for a job that uses a computer program to choose the most qualified person.

    “Most Americans want the government to limit automation. For example, 87 percent support a requirement that all driverless vehicles have a human in the driver's seat who can take control when an emergency occurs. And 85 percent want to limit machines to mostly doing jobs that are dangerous or unhealthy for humans. And only 25 percent expect more jobs to come from automation,” Pew said.

    Mark Zuckerberg, the co-founder of Facebook, spoke last May to graduating seniors from Harvard University in Massachusetts. His talk centered on the uncertain future facing young people. “Our generation will have to deal with tens of millions of jobs replaced by automation like self-driving cars and trucks.” Zuckerherg told the graduates.

    Zuckerberg said young people had better launch(发起)projects that will bring both jobs and direct benefits to the people of the world. He said in his speech that 30000 people worked to put a man on the moon, and millions of people built the Hoover Dam as well as other great projects over the last 100 years.

    The Silk Road is a name given to the many trade routes that connected Europe and the Mediterranean（地中海）with the Asian world. The route is over 6,500 km long and got its name because the early Chinese traded silk along it. Although silk was the main trading item, there were many other goods that travelled along the Silk Road between Eastern Asia and Europe. In the course of time, medicine, perfumes, spices and livestock（家畜）found their way between continents.

    The Chinese learned to make silk thousands of years ago. For a long time they were the only ones who knew how to make this precious material. Only the emperor, his family and his highest advisers were allowed to wear clothes made of silk. For a long time the Chinese guarded this secret very carefully. The ancient Romans were the first Europeans who became aware of this wonderful material. Trading started, often with Indians as middlemen（中间人）who traded silk with the Chinese in exchange for gold and silver which they got from the Romans.

    Travelling along the route was dangerous. The hot desert, high mountains and sandstorms made traveling a rough business. Most of the goods along the Silk Road were carried by caravans（商队）. Traders sometimes brought goods from one destination on the silk Road to another, from where the goods would be transported by someone else. Over the centuries people settled along the ancient route and many cities emerged. Later on there were fewer hardships to overcome, but by no means was it easy.

    Religion, languages and diseases also spread along the Silk Road. Buddhism, which originated in India, spread to China along this route. European traders probably brought the plague from Asia to Europe along the ancient road.

    In the early Middle Ages, traffic along the route decreased because of the decline of the Roman Empire. Trading along the Silk Road became stronger again between the 13th and 14th centuries, when the Mongols controlled central Asia. During the Age of Exploration the Silk Road lost its importance because new sea routes to Asia were discovered.

    Snowbirds are people who leave their homes when the temperature drops and head to warmer climates. They are mostly retirees(退休人员) and business owners who can afford(付得起) to take the winter off. While the snow flies in the Northern states, they are enjoying golf, sailing and barbecues in mild temperatures in the South. Then, after winter passes, they return to their homes in the North.

    Most snowbirds are away from Canada and the Northern states between the middle of October and the end of November. They pack up and head to Florida, Alabama, Texas, California, and all of the other Southern states. Some may even go as far as Australia or Italy to escape the cold winter weather. There are special communities(社区) for snowbirds in many areas. Snowbirds are also offered special discounts(折扣) in some restaurants, hotels and area attractions. Several states even have special snowbird resorts (度假胜地). There are several online communities and local resources to help snowbirds get set in their seasonal homes.

    Some snowbirds own homes both in the South and in the North. Both homes have everything they will need for their stay, minimizing(最小化) the amount of packing necessary when moving from one to the other. Other snowbirds will rent apartments for their stay outside their home state.

    RVs(房车), are a huge part of the snowbird lifestyle. RVs allow snowbirds to move from place to place on a whim (奇想), bringing everything they need with them. They spend nights in RV parks, large parking lots or anywhere else they choose to stay. RVs have beds, bathrooms, and most other modern conveniences at home. Although the space is small, there is more than enough room for a couple to live in.

    Summer's here and it won't be long before school-aged kids across America start complaining that they're tired of riding their bikes, playing at the park, swimming in the pool...and all the other awesome activities their parents hoped would keep them pleasant for the next 10 weeks. Well, if it's any comfort, such rapid boredom could suggest that the kids have amazing powers of memory. A new study shows that the better your short-term memory is, the faster you fed sated (过饱的）and decide you've had enough.

    "Though satiation can be physical, like when you feel full after eating too much, we were interested in the psychological (心理学的）side of satiation. Like when you're just tired of something," Noelle Nelson, assistant professor of marketing and consumer behavior. She and her colleague Joseph Redden at the University of Minnesota tried to think outside the lunch box." Something that was interesting to me is that some people get tired of same things at very different speeds. So if you think about pop songs on the radio, some people must still be enjoying them and requesting them even after hearing them a lot. But a lot of other people are really sick of those same songs."

    The difference, the researchers thought, might have to do with memories of past experiences. For example, studies show that people push away from the dinner table sooner when they're asked to describe in detail what they ate earlier for lunch.

    So the researchers tested the memory capacity (能力） of college students, The students then viewed a repeating series of three classic paintings…like The Starry Night, American Gothic, and The Scream...or listened and re-listened to a series of three pop songs...or three pieces of classical music. Throughout the test, the students were asked to rate （定等级） their experience from zero to tan. And the better a participant scored in the memory test, the faster they got bored." We found that people with larger capacities remembered more about the music or art, which led to them getting tired of the music or art more quickly. So remembering more details actually made the students feel like they'd experienced the music or art more often."

    The findings suggest that marketers could control our desire for their products by figuring out ways to keep us from fully remembering our experiences. We could also trick ourselves into eating less junk food by putting ourselves in the memory of a previous (之前的) snack. As for kids easily bored, just tell them to forget about it—it might help them have more fun.
