"How are you?" is a nice question. It's a friendly way that people in the United States greet each other. But "How are you?" is also a very unusual question. It's a question that often doesn't need an answer. The person who asks "How are you?" hopes to hear the answer "Fine", even if the person's friend isn't fine. The reason is that "How are you?" isn't really a question and "Fine" isn't really an answer. They are simply other ways of saying "Hello" or "Hi".

    Sometimes, people also don't say exactly what they mean. For example, when someone asks "Do you agree?" the other person might think, "No, I disagree. I think you're wrong…" But it isn't very polite to disagree so strongly, so the other person might say "I'm not sure." It's a nicer way to say that you don't agree with someone.

    People also don't say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person says "I have to go now." Often, the person who wants to hang up gives an excuse: "Someone's at the door." "Something is burning on the stove." The excuses might be real, or not. Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't polite to say that. The excuse is more polite, and it doesn't hurt the other person.

    Whether they are greeting each other, talking about an idea, or finishing a talk, people don't say exactly what they are thinking. It's an important way that people try to be nice to each other, and it's part of the game of language.

    Phone Soap: Charge and Clean Your Phone

    You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them—specifically, the bacteria called E. coli.

    The research on bacteria and viruses led to the invention of Phone Soap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation (辐射) used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges.

    “There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones,” says Wes Barnes, the Phone Soap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. “He realized he got the idea of getting rid of bacteria and viruses on the phones,” said Barnes. “In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines.”

    Phone Soap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the Phone Soap charger box. The process only takes a few minutes but, Barnes says, “The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully.”

    The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week's International Consumer Electronics Show in Las Vegas, Phone Soap was all grown-up. Both co-founders have left their previous jobs and are selling Phone Soap nonstop. “We're shipping almost more than we can handle each day,” Barnes says. “It's been a great adventure.”

    I was a shy girl. I didn't even like to answer the telephone for fear I'd have to talk to somebody I didn't know. I enjoyed the loneliness of exploring nature. However, at school I had to spend all day in the company of others. My escape was reading. I spent a lot of time studying and was rewarded with good grades. My only failure was Spanish—I'd get all. As on my written work and tests, but Ds and Fs on the spoken part.

    Eventually I went to college. During my third year of college, I had enough of being shy and determined to change my outlook and behavior. One day while at school, I noticed an advertisement for positions on the local classical music radio station. I had grown up listening to classical music, and I could easily pronounce names such as Tchaikovsky, Albinoni, and Chopin.

    I had absolutely no background in radio, and absolutely no hope of getting the job. The idea of talking to thousands of listeners in “radio land” terrified me. However, I luckily survived the interview. I was given brief descriptions of symphonies（交响乐）and a public service announcement to read, and a list of composers' names to pronounce. It wasn't hard for me. I left the recording session（录音时段）with a sense of relief and a sense of accomplishment. About two weeks later I actually landed the job. It was a challenging job, but I grew to enjoy it greatly. I began to feel comfortable talking to people.

    Although I now spend many hours each week talking with people, I'm still basically a quiet person. Perhaps it is my soft voice and my quiet nature that helps draw people out as they respond to my questions as I interview them. My former shyness is a fortune, as I can relate to people who feel discomfortable when they talk to newspaper reporters. I still enjoy moments of loneliness and the peace found in nature. But I'm also glad I decided to make a change in my life that has opened many doors and opportunities that I never knew existed.

The thing that sets children apart from adults is not their ignorance, nor their lack of skills. Rather, it's their enormous capability for joy. A friend told me a story. One day, when she went to get his 6-year-old son from soccer practice, her kid greeted her with a sad face. The teacher had criticized him for not focusing on his soccer drills. The little boy walked out of the school with his head and shoulders hanging down. He seemed wrapped in sadness. But before reaching the car door, he suddenly stopped, crouching(蹲伏) down to look at something on the sidewalk. “Mom, come here! This is the strangest bug I've ever seen. It has, like, a million legs. It's amazing!” The little face was overflowing with indescribable excitement.

Nowadays, however, when we walk into a classroom, especially in a high school, we'll be choked by towering books and papers, and hiding behind them are a group of motionless creatures, pens in hand, minds dry, just as the hollow men portrayed by T. S. Eliot. Their pursuit of joy has given way to their hunger for grades. Laughter and happiness are a distant memory for them.

    Although joy is an unaffordable luxury in today's increasingly fierce competition, administrators and teachers need a mindset shift from crushing students with assignments to getting them to take pleasure in productive activities which develop their important qualities, like perseverance and obligation. The assumption that pleasure is the enemy of competence and responsibility makes no sense educationally.

Adults tend to talk about learning as if it were medicine: unpleasant, but necessary and good for you. Why not think of learning as if it were food—something so valuable to humans that they want to experience it as a pleasure?

    When we talk about Americans barely into adulthood who are saddled with(担负着) unbearable levels of debt' the conversation is almost always about student loan debt. But there's a growing body of evidence suggesting that today's young adults are also drowning in credit-card debt and that many of them will take this debt to their graves（坟墓）.

    More than 20% overspent their income by more than $ 100 every single month. Since they haven't built up their credit histories yet, it's a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt.

    Although many young people blame "socializing" as a barrier to saving money, most of them aren't purchasing $ 20 drinks in trendy bars. They're struggling with much more daily financial demands.

    To a disturbingly large extent, the young and the broke are relying on credit cards to make it until their next payday. This obviously isn't permanent in the long run, and it's going to put a huge drag on their spending power even after they reach their peak earning years, because they'll still be paying interest on that bottle of orange juice or box of spaghetti (意式面条）they bought a decade earlier.

    A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups, and that they're slower at paying it off. "If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future'" warns Lucia Dunn, professor of economics at Ohio State. "If our findings persist, we may be faced with a financial crisis among elderly people who can't pay off their credit cards."

    Dunn says a lot of these young people are never going to get out from under their credit card debt. "Many people are borrowing on credit cards so heavily that payoff rates at these levels are not plenty to recover their credit card debt by the end of their life which could have loss impacts for the credit card issuing banks,"
