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.

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

    The next generation of artificial intelligence (AI) may be sitting right beneath you, at least if furniture maker Ikea has any say in the matter. The Swedish furniture company's “future-living” research lab in Copenhagen is conducting a survey to understand what people want when it comes to smart furniture.

    AI is now walking into more aspects of people's daily lives. Self-driving cars are just around the corner, and AI robots can play and beat the best players of strategy games. As smart home technologies have become more ubiquitous, products ranging from smart electrical outlets（插座）to smart smoke alarms are flooding the market. Therefore, it's not surprising that Ikea would be moving in the same direction.

    Exactly why people would want their sofa or bed frame to speak to then, track their daily movements or offer help is not yet clear. Though Ikea's the new survey doesn't directly answer that question, it does provide a hint of what people would feel comfortable with. Most participants wanted a more human0like form of virtual（虚拟的）assistants, as opposed to one that is more robotic. In terms of the ideal gender（性别）of the assistants, the most popular choice was neither male nor female. Few wanted a religious form of AI.

    Just as with human friends, most wanted AI friends that were like them, affirming their own worldview. They wanted an AI assistant that was reasonably intelligent-that could collect data to predict what a person wanted before he or she asked, and that could prevent someone from making mistakes.

    This is not the first time that Ikea has set foot in the field or futuristic technologies. In addition to wireless charging tables and chainless bikes that never rust（生锈）, the furniture giant has also pictured smart kitchens that can cook the best meal. To decide on how intelligent you want your next sofa or bookshelf to be, you can take Ikea's survey online.

    When traveling in England, here are some things to keep in mind.

    When taking the underground in England, once on the underground train, stand clear of the closing doors. They can give you a pretty hurtful knock if they hit you. When getting on or off the tube train, make sure you mind the gap(缝隙)! This varies from a few inches to a foot at some of the stations.

    The saying that English food is boring and tasteless isn't true, at least not anymore. You'll find a huge variety of international restaurants, especially in London. Make sure you eat some of the old-fashioned traditional foods in pubs, and wash it down with some local beer!

    Come prepared for any sort of weather ——even if the day starts off well, it's likely that the temperature will change. The best thing to do is layer(分层穿套) your clothes so that you can add or reduce as necessary.

    The British are in general very polite people and will expect at least basic politeness from travelers. Pleases and thanks go a long way! At the same time  they like playing jokes on others. Don't be surprised or offended if you're called darling, dear, dearie, flower, love, chick, chuck, me duck, son, ma'am or any other similar pet name by someone you don't know. It's quite normal.

    England is generally quite safe, but you'll need to be more careful in London and the other large cities, especially at night. Choose an underground train that has plenty of people in it and avoid suburban underground stations at night. There are many night buses you can catch, but try not to do this alone. A licensed cab is often the best choice. Try and leave valuable things in your hotel room, as pickpockets(扒手) do operate in some areas. Be careful of bags especially when in some busy areas.

    Mr. Bean is an internationally recognized comedy character on TV and in films. He constantly gets into awkward and absurd situations, which greatly amuses audiences regardless of their nationalities or culture. The humour is always made clear through a series of simple and funny acts that rely purely on body language, which is universal.

    One of my favourite shows is that Mr. Bean has a meal in a fancy restaurant. After being seated at his table, Mr. Bean takes out a card, writes a few words on it, seals (密封) it in an envelope and places it on the table. After a moment, he looks back at the envelope but this time he looks surprised, as if he did not know it was there. He opens it to find a birthday card and delightedly puts it on the table for everyone to see.

    When he looks at the menu, an astonished look swiftly appears on his face. He takes all the money out of his wallet, counts it and puts it in a saucer (茶托). He then looks from the menu to the money with concern until he finds one thing that makes him smile. Then he orders a dish called "steak tartare". When the dish arrives, he is shocked to discover that "steak tartare" is actually raw hamburger. He makes an attempt to eat it, but it is clear from the look on his face that he finds the taste truly disgusting. He cannot hide his feelings, except when the waiter asks if everything is all right. When this happens, he smiles and nods, indicating that everything is fine. When the waiter is not looking, however, he busies himself hiding the raw meat anywhere he can reach-the sugar bowl, the tiny flower vase, inside a bun (小圆面包) and under a plate. He becomes so desperate in the end that he even hides some inside the purse of a woman sitting near him and throws some down the trousers of the restaurant's violinist!

    I like to watch Mr. Bean on TV, but I wouldn't like to meet someone like him in real life and I certainly wouldn't like to have dinner with him!

    We often hear stories of animals rescuing people. But now someone has managed to return the favor.

    The event took place one snowy January morning Thomas Smith was walking his dog, Jack, in the park." As I was walking, I just saw Jack running onto the ice towards the ducks in the middle, and then he fell into the water and couldn't climb out, "said Smith. He realized he had no choice but to try and save his dog. "Someone else told me the lake was only one-meter deep, but it was at least twice that. I had to break my way through the 6-cm ice. Finally, I got Jack by the neck, and pulled him out. I don't think I have ever felt so cold by the time we got back to dry land. And when we got there, everyone was asking if Jack was okay no one was particularly worried, about me!"

    A neighbor, Julie Brown, saw it all happen. "The dog went onto an icy lake. All of a sudden, it started to go under. There were crowds of people around, and they were all shouting and screaming. Before I knew it, the owner Smith was in the water forcing his way through the ice. I can't begin to imagine how cold it was. Everyone was very nervous, but he was as cool as a cucumber he just crawled back out, put the dog on its lead, and went home."

    Many regard him as a hero, but Mr. Smith is quite laid-back about it. "Most dog owners are the same as me. They would do what I did without a second thought. But in the future, I'm going to make sure he's on lead near any ice ponds, Pets are members of our family. Would you do the same for them?
