“Did you hear what happened to Adam Last Friday?” Lindsey whispers to Tori.

    With her eyes shining, Tori brags, “You bet I did. Sean told me two days ago.”

    Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedman. I can tell you that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren't very different from most students here at Linton High School, including me. Many of our conversations are gossip(闲话). I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.

    An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic–breakups, trouble at home, even dropping out-that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.

    If we know that gossip can be harmful, then why do so many of us do it? The answer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor can make a person feel important because he or she knows something that others don't. Similarly, hearing the latest rumor can make a person feel like part of the “in group.” In other words, gossip is satisfying because it gives people a sense of  belonging or even superiority(优越感).

    Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The do's and don'ts conveyed through gossip will never show up in any student handbook.

    The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, think about why you want to gossip and what effects your “juicy story” might have.

    During this shopping season, salesmen will come up with different strategies to get your business. Many product companies use specific colors to cause positive emotions and compete for a sale. However, sight is not the only sensory (感官的) retail that companies use. Sounds and smells can also influence consumers' purchasing decisions.

    Nobel Prize-winning research shows that our sense of smell has great power to cause an emotional response. A study published earlier this year compared purchasing in a French flower shop when the smell of lavender (薰衣草) was given off and when it wasn't. It found that the smell increased the number of consumers' purchasing items and the amount of their purchases. An earlier study using Nike shoes found that consumers desired the shoes more, and were willing to pay more, when the room had a mixed smell of flowers. Realizing the subconscious impact of smell, many stores apply artificial scents (气味) through their heating and air-conditioning vents (通风口) or place scent machines above their doors. For instance, a coconut scent might make that bikini more appealing as you long for a vacation.

    Ever felt frenzied due to a store's fast-paced music? Or calmed by a piece of light music? A retailer's choice of music can have a big impact on consumers' moods. One study found that when subjected to loud music, consumers will spend less time in a store. But interestingly, the researchers did not find a difference in sales or customers' satisfaction. Another interesting finding from a recent study was that customers actually shop longer when exposed to unfamiliar music. Just as department stores use different scents in certain departments, many use different music in some areas to appeal to varying consumers.

    Well, you could always leave the store and take a break, but the food court probably isn't your best choices as brands like Cinnabon and Panera Bread also use scents as part of their customers' experience. Online retailers (零售商) use a variety of other strategies to get your business, but you can always neglect those and enjoy the familiar scents of home.

    The annual celebration of St. Patrick's Day is coming soon to the Canton Tower. St. Patrick's Day is an Irish cultural and religious celebration occurring annually on March 17. The festival celebrates the life of St. Patrick, who helped the poor and taught the Irish people good things, The Lanton lower has become one of, the premier (最初的)party sites for this international and lively event. As part of the celebration, the tower will brighten the night with brilliant light shows. Participants (参加者)are sure to enjoy the festive Irish atmosphere.

    As in the past years, camping lovers will gather to spend a night beneath the Canton Tower, The time for the camping adventure will be from 3 p. m. on March 17 to 9 a. m. on March 18. The event offers people a great chance to enjoy this special and free camping site.

    Artists will perform a range of music with instruments played typically in Irish folk music, featuring tin whistles and wind pipes. Foodies also will be in for a treat, as the taste of traditional Irish food will surely attract everyone.

    To celebrate this festival, dancers dressed in Irish green, the colour of Ireland, will pop up around the Canton Tower. The parade will go along the main streets and thousands of people will watch, waving flags. Good luck if you meet with these "green spirits."

    I didn't know how to say no, and was afraid to tell people what I wanted. Instead, I got myself tangled (纠结的) in a web of obligations, anxiety, and white lies.

    The worst thing was that I didn't even realize what I was doing. I thought I knew how to say "no"—but couldn't remember the last time I had. Like a lot of people, I just wanted to be accepted, appreciated, loved—and that the only way to get those things was to put everyone else's needs before my own.

    I never seemed to have time for things I really wanted to do. I'd like to learn Spanish, write more fiction, and travel. These aren't huge, unrealistic goals. And yet, my people-pleasing ways dramatically cut into my free time to pursue these desires.

    But recently, I decided I'd had enough. As an experiment, I began standing up for myself, even at the risk of alienating (使疏远) myself from everyone and having my entire life come crashing down around me. Several days ago, a good friend asked me to go for coffee at 5 p.m. I was planning to hit the gym and then binge—watch Mad Men for the millionth time. I said, "Sorry, I've got things I want to do tonight." She said, "That's fine. Maybe another time." It was all so painfully simple that I wanted to cry.

    Saying "no" is so much easier. If someone asks me to do something I have zero interest in, I'm polite but honest. "I'm sorry, I don't think that's really for me." The words slip out my mouth faster than some other lame excuses.

    Learning how to say "no" has added several extra hours to my days, days to my weeks, and what feels like months to my years. I no longer have to back-burner my plans to help friends with their job search, or set aside a weekend to read a book draft by someone I barely know. Saying "no" has set me free.

    A butterfly's wings can have many jobs besides keeping the insect in the air. They may be called on to attract mates, to warn potential enemies to stay away, to do other animals or even to provide disguise(伪装).

    All of these roles, though, depend on their colouration-which is unchanging. This plays into the idea that butterfly wings are dead tissue, like a bird's feathers or a mammal's hair. In fact, that is not true. For example, in some species males' wings harbour special cells that release chemicals which attract females.

    Nanfang Yu, a physicist at Columbia University, in New York, has been looking into the matter. One of his interests is the optical (光学的) properties of biological materials. That has led him to study butterfly wings in more detail. And, in cooperation with Naomi Pierce, a butterfly specialist at Harvard University, he has now shown, in a paper published this week in Nature Communications, that butterfly wings are, indeed, very much alive.

    Initially, Dr Yu and Dr Pierce wanted to know how the insects keep their body temperatures up without their wings overheating. Unlike birds and mammals, butterflies do not produce enough internal heat to metabolize(新陈代谢). Instead, they rely on outside heat sources-usually the sun-to bring their bodies up to speed. But their wings, being thin protein membranes (膜), have a limited thermal capacity. Those wings can therefore overheat quickly if the insects are exposed to the sunlight too long, or, oppositely, can cool down too rapidly if they are flying through cold air.

In their experiments, the two researchers used a laser (激光) to heat up spots on the wings of dozens of butterfly species. When the temperature of the area under the laser reached 40℃ or so, the insects responded within seconds by doing things that stopped their wings heating up further. These actions included a butterfly turning around to minimize its exposure to the laser, beating its wings or simply walking away.

With advanced communication technologics making the iconic British red telephone boxes expendable (可抛弃的）, a US firm is all set to bring them back to use. Call boxes would be changed into mini-offices for workers on-the-go and will offer free coffee to subscribers (认购者).

Bar Works Inc's chief executive Jonathan Black, a Briton living in New York, said that his company will renew telephone boxes with fully functional printers, scanners, 25-inch screens and Wi-Fi. Bar Works specializes in offering bar-themed work stations in prime locations, charging customers with a monthly subscription in return for free access to the business and office supplies. The company plans to operate in a similar manner, offering British customers with monthly memberships to "Pod Works" for £19.99 ($29).

The company will refit telephone boxes in five major British cities and has already rented and changed 15 old call boxes in London and Edinburgh. As expected, they are coming into use by the public in the coming months. "Given the prime location, above all else, of the telephone boxes, the launch is expected to gain at least 10, 000 members by the end of 2021. It's an alternative to, say, Starbucks but obviously it provides you with total privacy. " said Black.

Thanks to mobile phones, the red telephone boxes have been effectively made expendable. According to a report by the Daily Mail, retired telephone boxes, especially those damaged deliberately, are sent to a "telephone box graveyard" of sorts, where they take great pains to restore to their former glory before being sold to collectors across the globe. Such is the demand for properly restored telephone boxes, that it is not uncommon for them to be sold for amounts as high as £10, 000.

Despite its setback, in a recent survey, the British red telephone box, which was originally designed in 1920, was voted the greatest British design of all time.
