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. For 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 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.

     “Sugar, alcohol and tobacco,” economist Adam Smith once wrote, “are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation.”

    Two and a half centuries on, most countries impose (征税) sort of tax on alcohol and tobacco. With obesity levels putting increasing pressure on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.

    Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales of untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, during claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier foods.

    The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.

    Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages (饮料).

    Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.

    While reformulating (再制定) recipes is one way to improve public health, it should be part of a multisided (多边的) approach. The key is to remember that there is not just one solution. To deal with obesity, a mixture of approaches, which include reformulation, taxation and adjusting portion sizes, will be needed. There is no silver bullet.

    Everything has a name. All people, places and things have names. For example, Jenny is the name of a student from England. England is the name of her country. Cities and towns have names, too. Schools and office building also have names. All things have names. Names are important.

    Names are different all over the world. In Jenny's class, Jenny must learn the names of students from all over the world. This is very difficult because the names are different.

    In the USA, most people have a first name, a middle name, and a last name. Parents choose the first and middle names for their baby. There are names for boys and names for girls. For example, John, Peter, Tom and Mike are all names for boys. Elizabeth, Betty, Susan, and Mary are all names for girls. The last name is the family name. Usually it is the father's family name. In a family, the mother, the father, and the children usually have the same last name.

    Names are different all over the world. They can be long or short, but they are always very important.

    Many independent Chinese women like to earn their own bread, even if their husbands are already bringing home the bacon. But a recent survey suggests that such women find more joy from relationships, rather than successful careers.

    About 73 percent of the 7,000 women surveyed in Beijing, Shanghai and Guangzhou said they would choose to work even if their husbands earned enough for the family. The survey also found that 77 percent define happiness as "enjoying a relationship".

    But striking a balance between career and family can bring challenges to the woman's career advancement.

    "In my company, women usually have an equal or even a higher starting salary than men," said Li Hua, general manager of Beijing Chuangjiashe Book Circulation Company. "However, as they begin to climb up the career ladder, women often meet problems along the way, while men can climb the ladder more easily."

    Both physical and emotional differences can prevent some women from taking tough positions, Li said. But family life is often the main difficulty for Chinese career women.

    Despite these challenges, however, some experts believe it's reasonable for some women to want to be breadwinners.

    "In this way, the roles of a family are decided by the parents' abilities rather than their gender（性别）," said Gu Donghui, a sociology professor at Fudan University.

    Gu says women should have the freedom to decide if they want to stay at home or work to support the family. "Everyone has a different interpretation（解释）of what it means to find self-worth".

    Wang Haibin, an economic expert from Renmin University shares that view: "Traditionally, we tend to regard the family as the cell unit of society. Some members have always been expected to make sacrifices for it. But, it really doesn't matter who earns more. Economic independence and personal choice is essential for both sexes in the family."

    When Lina was awoken by the sound of thunder, she was alone on the island. The air was cool and bullfrogs croaked. It was that brief moment when the summer sun had set but the stars hadn't yet appeared. Lina rubbed her eyes and looked around.

    "Hello?" she called. "Celia? Marie?"

    There was no response.

    The moon was rising now, shedding light on the island. They had always called it "Forgotten Island" because no one but they seemed to remember its existence. It wasn't on any of the maps they could find, and even the forest rangers didn't know about it. Lina loved that the island, hidden in a heavily-wooded side stream of the river, was a secret between the three friends -her, Celia, and Marie.

    But now Lina was here alone, and it was night. Worse still, it was her own fault.

    "Come on, Lina, let Marie row the boat." Celia had said. Marie was two years older than Lina, but she was a hopeless rower. That's why Lina refused and rowed the boat to the island. The argument that followed the refusal took the usual form. Celia took Marie's side, as she always did. Lina had exploded and yelled at them to just leave. So they got back in the boat and left.

    A bolt of lightning crossed the darkened sky, accompanied by a deafening thunder clap. The storm was here. As the first cold raindrop slid down her neck, Lina's mind returned to her current problem. She was stuck here by herself. She just hoped she didn't become as forgotten as the island. The thought of it sent a chill（寒意）down her back.

    Suddenly, Lina spotted something in the water. It was a boat, and inside it were Marie, Celia, and Marie's dad, who was steering through the fast flowing waters. As the boat approached, they saw Lina waving and the worried expressions on their faces turned to relief.

    In her excitement Lina jumped into the river. Only once she was in the icy water did she remember how fast the water was moving. Luckily a strong arm reached into the water and pulled her out. She smiled weakly at Marie's dad and, without a word, hugged Celia and Marie. They didn't seem to mind becoming wet.

    For the business traveler who's all about efficiency: check out these hotels that will get you in and out with a minimum trouble.

    When you're pressed for time on a business trip, nothing can annoy you more than a slow hotel check-in process. On your next trip, try these hotels that offer a speedier check-in process.

    ◆Marriott Detroit Airport

    Another option for business travelers in a hurry: Marriott is rolling out its mobile check-in app to 325 hotels this year, including the Marriott Detroit Airport hotel. (I've tested the app itself but not for a real visit quite yet.) here is the basic idea: you download the iPhone or Android app. The night before, you can "check-in" virtually. When you arrive, you get an alert that the room is ready and your key, which is already tied to your reservation, is waiting for you at the desk.

    ◆Hyatt Regency Minneapolis

    I happened to stay at this hotel recently and liked how fast the kiosk check-in works. The kiosk asks you to insert your credit card, similar to an airport terminal. The whole process took about 3 minutes. When I left, I was equally impressed with the fast check-out: An agent meets you in the lobby with, an iPad and asks for an email to use for a receipt. The big advantage: you never have to wait in line.

    ◆Radisson LaCrosse

    The Radisson is trying to make the kiosk process even faster. At a few select hotels like the Radisson Lacrosse in Wisconsin, you use a mobile app to register and then receive a barcode by email or text. When you get to the kiosk, you can scan the barcode to get your key without any other steps required. It's super fast. You can find this new check-in system at the Radisson hotels in Salt Lake City, Seattle, and Phoenix as well.
