“People are ruder today because they are rushed and more 'time poor' than ever before，” says Patsy Rowe, “Manners_have_fallen_off_the_radar(雷达)．” Due to our strong attraction to electronic equipment it is a wonder more people don't wake up each morning and greet the singing birds with a complaint(抱怨)about the noise. Here are some examples of rudeness.

    Some people prefer to do almost everything over the Internet. To them, dealing with an actual human needs more patience. It feels very slow because humans don't work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life－changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous(匿名的) rude messages by email.

    However, rudeness is never acceptable. Don't assume it is OK to be rude if the person you're in touch with won't recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.（令人厌恶的）

    We shouldn't blame technology for our shortcomings. Technology is here to help us，but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more helpful if we'd publicly acknowledge good manners when we see them.

    When your child lies to you, it hurts. As parents, it makes us angry and we take it personally. We feel like we can never trust our child again. Why does lying cause such anger, pain and worry for parents?

    Parents are understandably very afraid of their children getting hurt and getting into trouble, but they have very little protection against these things as they send their kids out into the word. Kids learn from other kids and from external media, and this makes parents feel unsafe because they can't control the information and ideas that their children are exposed to.

    When your kid lies, you start to see him as “sneaky（卑鄙的）”, especially if he continues to lie to you. You feel that he's going behind your back. You begin to think that your kids are “bad”. Because, certainly, if lying is bad, liars are bad. It's just that simple. Parents need to make their kids responsible for lying. But the mistake parents make is that they start to blame the kid for lying. It's considered immoral to lie. But when you look at your kid like he's a sneak, it's a slippery slope （滑坡谬误）that starts with “You lie” and ends up at “You're a bad person”.

    Kids know lying is forbidden. But they don't see it as hurtful. So a kid will say, “I know it's wrong that l eat a sugar snack when I'm not supposed to. But who does it hurt?” “I know it's wrong that I trade my dried fruit for a Twinkie. But it doesn't really hurt anybody. I can handle it. What's the big deal?” That's what the kid sees.

    So I think that parents have to assume that kids are going to tell them lies, because they're immature and they don't understand how hurtful these things are. They're all drawn to excitement, and they'll all have a tendency to distort（歪曲）the truth because they're kids.

    Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. So he took a short business course, and went to work as a salesman in a large city.

    Woolworth realized he had a natural skill for showing goods to attract people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.

    Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities(大量) directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.

    By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made a lot of money and his name became famous throughout the world. He always ran his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.”

    A medical study has shown that excess(过度的)coffee drinking could cause heart attacks in people who do not metabolize(使新陈代谢)caffeine fast enough.

    The study, published recently in the Journal of the American Medical Association, says an enzyme(酶)that metabolizes caffeine in the liver works differently in some people, depending on the make­up of the gene(基因). People who have a slow version (版本)of the enzyme are at a greater risk(风险)of a heart attack when they drink more coffee. The risk had something to do with a person's age and how many cups of coffee he drinks.

    The team from the University of Toronto in Canada studied 4,024 people living in coffee­rich Costa Rica between 1994 and 2004, of whom half suffered non­fatal(非致命的)heart attacks. They found slightly more than half had the slow version of the gene, while the rest had the fast form.

    Two to three cups of coffee a day increased the possibilities of a heart attack by 36 percent for those with the slow­acting gene and four or more cups a day lifted it by 64 percent.

    But those under 50 who had the fast version of the gene had a lower risk of heart disease, even with four or more cups a day.

    Those with the fast­acting gene who drank two to three cups of coffee a day had 22 percent reduced possibilities of having a heart attack, but drinking four or more cups a day only lessened the risk by 1 percent. Scientists recommend limiting coffee consumption(消耗量)to within four cups a day.

    Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees' natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.

    Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.

    We've all fantasized about it—after a rough day at work, stuck in traffic with commuters (上下班的人) we'd rather not have in our personal space, and bills to pay, plus the sound of the crying baby in the apartment next door. How nice would it be to go solo and live on an island of one, population: me?

    Well, this is the reality for 84 year old Elsie Eiler of Monowi, Nebraska. She is the sole resident of her hometown, which is the smallest recognized locality in the United States.

    Looking back at the 2000 census (人口普查), the town used to have another resident: Elsie's husband Rudy. Since he died in 2004, Elsie has lived in the town by herself. She considers herself to be the mayor, treasurer, and town librarian. Her main source of income is the bar that is frequented by truckers and other people passing through—the Monowi Tavern, which she founded with her late husband back in 1971 . She received a lot of public attention after it was discovered that she was the sole resident of Monowi, and in an interview she stated that many visitors from around the world have come to meet her in Monowi.

    When asked if she ever gets lonely, she said "I know I could always move closer to my children or stay with them whenever I want, but then I'd have to make all new friends again. Hopefully I will be able to stay here. It's where I want to be."
