Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation (感觉) of warmth encourages emotional (情感的) warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist (心理学家) John A. Bargh.

    Psychologists have known that one person's perception (感知) of another's “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable (能干的). Much of this is rooted in very early childhood experiences, Bargh argues, when babies' sense of the world around them is shaped by physical sensations, particularly warmth and coldness.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses (假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly (抽象的),” says Bargh.

    In the movie Alice in Wonderland, Alice comes across a Cheshire cat and asks the cat which road she should take. The cat responds, “Well, that depends on where you're trying to get to.” Alice replies, “I don't know.” The cat responds, “Then any road will do.”

    You see, knowing where you're going increases your chances dramatically of getting there, and there is no better way of “GETTING THERE” than setting your goals for the upcoming year. Think of your goals as destinations and the action steps as your GPS guiding and directing you. If you are like many other people, for years you have resisted the need to set goals and even laughed at the thought that setting goals and, even more importantly, committing them to writing have positive effects on your life. However, a closer look might convince you that setting goals is a sensible thing to do.

    In 1979, a class of Harvard MBA students was asked: Have you set clear, written goals for your future and made an action plan to accomplish them? The following will astonish you. Only 3 percent of the class had written goals and a plan in place, 13% just had goals, and an amazing 84% had no specific goals at all.

    Ten years later the numbers of the class were interviewed once again and the following results will no doubt give the reason for our setting goals. The findings were that the 13% who had goals were earning, on average, twice as much as the 84% who had no goals at all. And the 3 percent who had clear, written goals with a plan to achieve them were achieving ten times as much as the entire 97% combined.

    Goal setting will increase your chances of arriving successfully at your destination. Remember, always set SMART goals. Goals should be: Specific, Measurable, Attainable, Relevant, and Time-bound!

    If all the food that's thrown away in three American cities could be saved, it would provide 68 million meals for people who don't have enough to eat, according to a recent study.

    The researchers found that, in the cities they surveyed（调查）, more than a kilogram of edible food per person is wasted each week. Edible food is food you can eat. It doesn't include things like apple cores（果核）, egg shells, or bones from meat. Fruits and vegetables were the most common edible foods found in the dustbin, followed by food leftover from meals. Eggs, bread and milk were also commonly thrown out.

    The people taking part in the survey gave several reasons for throwing edible food away. Most said the food went off. Some said they weren't interested in eating leftovers. A few said the food had passed the “Best Before” date printed on the label（标签）. When food is wasted—by families, restaurants or grocery stores—we are also wasting all of the resources that go into producing that food. That means we are wasting water, land, energy and labour, as well as the fuel needed to transport food.

    A lot of food is wasted before it even reaches the grocery store（食品杂货商）. Some food is damaged while it is being transported from the farm to the stores. Fruits and vegetables that don't look attractive enough don't even get put onto the shelves because most people won't buy them. Grocery stores, restaurants and hospitals also waste a large amount of food. The researchers suggest that grocery stores should donate any food that is still okay to eat to homeless shelters, instead of throwing it away. Prepared meals from hospitals or restaurants could also be donated to shelters.

    Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time—about eight hours after you wake up—your body temperature goes down. This is what makes you slowdown and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.

    In many parts of the world, people take naps in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap—even ten minutes of sleep can be helpful.

    Does your local high school have a student newspaper? Only 1 in 8 of New York's public high schools has student newspapers – and many of those are published just a few times a year. A few more are online, which can leave out poorer schools.

    Rebecca Dwarka, an 18-year-old senior who works for her student paper said, “Facebook is the new way of finding out what happened. Nobody wants to actually sit down and read a whole article about it. This makes a 'whole article' sound a little like a long sentence in lonely places.”

    I am not nostalgic about high school student newspapers and never worked for mine. I put out what was then called a personal magazine with a group of friends because we wanted to write about peace, war and rock 'n' roll without school officials warning us not to make jokes about the local officials.

    School newspapers are in decline because students now find out what happened on social networking websites. This is a little discouraging because it proves that for millions of Americans, journalism is becoming a do-it-yourself thing. Every citizen can be a reporter.

    When something happens, we look for social media messages. Facebook posts and Tweets have become the means by which citizens and reporters can prove, deny, pass on stories and express opinions without the press' challenging, researching or slowing the message.

    But truly good journalism is a craft, not just a blog post. It requires seeing something carefully and it uses an eye for details to help prove a larger view. And even journalism that conveys an opinion tries to be fair. If school newspapers begin to disappear, I hope there are other ways for students to learn that.

    Your next car could have two seats, three wheels two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in (he center with the passenger directly behind.

    The starting price for the car is just ＄6.800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motora. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on," he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.
