In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead,with more tactics（策略）.

One tactic involves where to display the goods. Foe example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food（垃圾食品）later in their trip. In department stores, section is generally next to the women's cosmetics(化妆品) section：while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over cosmetics they might want to try later.

Besides, businesses seek to appeal to customers' senses. Stores notice that the smell of baked goods encourages shopping, they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wine went up.

           When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decision in the first few second upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the poll through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.

    Teens don't understand the big fuss (小题大做). As the first generation to grow up in a wired world they hardly know a time when computers weren't around, and they eagerly catch the chance to spend hours online, chatting with friends, so what?

    But researchers nationwide are increasingly worried that teens are becoming isolated, less skillful at person-to-per son relationships, and perhaps numb to the cheatings that are so much a part of the e-mail world. "And a teen's sense of self and values may be changed in a world where personal connections can be limitless," said Shetty Turkle.

    Another researcher, Robert Kraut, said he's worried about the "opportunity costs" of so much online time for youths. He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. "Chatting online may be better than watching television, but it's worse than hanging out with real friends," he said.

    Today's teens, however, don't see anything strange in the fact that the computer takes up a central place in their social lives. "School is busy and full of pressure. There's almost no time to just hang out," said Parker Rice, 17 "Talking online is just to catch time."

    Teens say they feel good about what they say online or taking the lime to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don't want to do so. But they insist there's no harm.

    10 years after my parents got married, my dad went to work in the oil fields, and soon accepted a job working overseas. The money was great, but the fact that we only saw him every other month disappointed me. My mom stayed home with her five children, raising us alone. We had a place in the country with horses, dogs, chickens and a few head of cattle. Mom was very busy, but always made time for us. Of course, lots of mothers did things like that. But Mom's greatest achievement was yet to come.

    When the oil business declined(衰退) in the 1980s, my dad and most of his friends lost their jobs. The wives were at a loss to know how to manage without large monthly paychecks. But my mom was different. She helped out by working part-time jobs and she learned to drive a semi-truck, so she could help my dad make more miles at his new job. But with three teenagers at home, she couldn't spend time on the road with him, so he decided to find a different kind of job.

    Mom found an ad for the International Air Academy in Vancouver, Washington. She had always dreamed of working as a flight attendant but had chosen a family over a career. She was fascinated by the idea that she might be able to work in the travel field after all. Having no idea how she would pay for the schooling, or even if she'd get a job, she took a leap of faith(冒险一试) and dialed the number.

    It wasn't easy, but she passed the entrance exam and was admitted to the three-month training course. That was only half the battle, though, as she still needed the tuition. She finally got a loan( 借款) to cover some of the expenses, and the president of the school gave her a personal loan to cover the rest.

    As she read her welcome packet, she realized there was a strict dress code( 着装要求), requiring professional dress each day. This was not something she had. And she also needed to see an eye doctor. Her older brother sent her enough money to buy the clothes she needed and test her eyes. And then she took her two youngest － daughters my sister and me to Vancouver, where there was an apartment waiting for her in the family housing section.

    In the first day of class, she was so nervous. I can remember her taking deep breaths and trying to calm herself before leaving. She was forty-five years old, and that made it a little intimidating to walk into a classroom full of twenty-year-olds and try to hold her own. But she stood by her commitment and graduated at the top of her class.

    Her first job as a travel agent was with a large agency in Aurora, Colorado. She felt great about her achievement and proud of the beautiful high-rise building she worked in. I was so proud of what she had done. She'd found a way to rise above the curveball( 弧线球) life had thrown at her. Instead of quitting as many of her friends had, she charged ahead and created a brand new career.

    After shopping for deals in stores on "Black Friday", or online on "Cyber Monday", Americans and people worldwide are preparing for newly popular "Giving Tuesday". Starting in 2012, now the global event that is celebrated annually on the Tuesday after Thanksgiving is the brainchild of 92nd Street Y, a cultural center in New York City and United Nations Foundation.

    As the name indicates, Giving Tuesday is meant to restart the charitable season and therefore observed by raising funds for local nonprofits and schools, organizing food and clothing drives, and conducting random acts of kindness. In 2015, 700, 000 people from 71 countries came together to donate $116.7 million in cash. An additional $1.08 million was spent on gifts.

    While the easiest way to participate is by donating to your favorite charity, this day can be celebrated in many other ways too. You can give back by volunteering at your local shelter or food bank, or even by donating blood. If all else fails, a purchase from the growing number of organizations that give a portion of their sales to charity will do the trick.

    But perhaps the best way to celebrate the day is by helping those nearest and dearest to you. Assist a family member with a simple chore like folding laundry, cooking dinner, or even reading to a younger sibling. No matter what you do, be sure to share you good deed on social media and inspire others to celebrate Giving Tuesday as well!
