The Future of Technology

    William, a businessman, arrives in a foreign airport. He doesn't show his passport. Instead, a machine in the wall reads the computer chip（芯片）in his arm. This contains information about him: his name, age, and I.D number. He exits the airport, and a car door opens when it “sees” him. The car takes him to his hotel. His room “knows” he has entered the building and it “reads” his body. He is cold, so the room becomes warmer. William then watches a business presentation on a video wall. When he takes a bath, the presentation “follows him and continues ”on the bathroom wall. Finally, the room plays music to help him sleep. It turns off the music when it “sees” him sleeping.

    William doesn't exist, and none of this is real. But it might be soon. “In five to ten years, computing and communications are going to be free and everywhere, in your walls, in your car, on your body,” says Victor Zue, leader of Project Oxygen.

    Project Oxygen has one big idea: to create better relationships between machines and people. The dream is that computer will learn to understand what people want.

    So, what changes will there be at work? Firstly, the building will know where everyone is, all the time. You want to talk to someone? Type the person's name on the nearest computer. It will show you a map of the building and exactly where this person is. You then call this person, who picks up the nearest telephone, also shown on the computer. If he or she is busy with a client（客户）or in a meeting, the computer will tell you.

    Is all this really possible? Visit the Siebel Center, Illinois and see for yourself: computers in the doors and walls, cameras everywhere, the technology of the future, but here today.

    Both humans and animals have enemies. It is easy for us to know the difference between our friends and our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat(威胁) and those who do not. In Kenya, researchers find that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear(刺)animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

    In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants noticed the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they noticed the smells of either clothing worn by Kamba men or clothing that had not been worn at all.

    Clothing color also plays a role. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively(攻击地) toward the red clothing.

    The researchers believe that the elephants' emotional(情绪的) reactions are due to their different senses of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.

    Lennon Flowers' mom was diagnosed with lung cancer when she was a senior in high school. This young woman gave up her big dreams to go to New York University and become an actor and instead entered the University of North Carolina so she could be close to home. Though she was surrounded by a community of friends, she rarely brought up her mom. “I became good at not talking about what was happening to me,” she explains. “I got really, really good at being really, really busy.”

    When her mother died during her senior year in college, many of Lennon's friends hadn't even known she was sick. In part, she said she kept silent about it due to her belief that it protected other people.

    Three years after her mother died, Lennon moved to Los Angeles for a job and, met Carla Fernandez. They had an immediate connection. Later, while apartment hunting side-by-side, Carla admitted that her father had died just six months earlier. Lennon shared her own story. A seed was planted.

    A couple of months later Carla organized a dinner party for five women, Lennon among them. All of them had lost a parent already though they were only in their 20s; all of them had felt alone in that loss.

    An emotional movement was born: The Dinner Party. Today, there are 31 “tables” across the country and the initial organization plans to create even more.

    Lennon says, “As people gather month after month, they branch out from talking about their lost loved ones and start exploring what those losses have taught them about the meaning of life.”

    In modern society, it is usually considered good to be an extroverted(外向的) person. This means that life can be hard for introverted people. Their talents and abilities are often not recognized.

    Some people often try to make introverts more outgoing. They think that being an introvert is a problem. But there is nothing wrong about being an introvert. Introverts are not necessarily afraid of meeting and talking to others. They simply prefer to spend time on their own, away from the crowds. They like reading, writing and taking walks in the countryside. But extroverts need other people. If they spend a lot of time on their own, they get bored. They tend to be impulsive and talk a lot.

    Our society puts a lot of pressure on people to be extrovert, to be outgoing and self-confident on every occasion. Susan Cain, the author of the book Quiet: The Power of Introverts in a World That Can't Stop Talking, has spoken about this problem. "I was nine years old," Cain says. "In my suitcase there were lots of books. This seemed normal to me, because in our family we always read a lot. I thought it would be the same at summer camp. But I was wrong. To create camp spirit, all the children had to sing a cheer every morning. I couldn't understand why. In the evening, I took out a book from my suitcase. But another girl said, 'why are you being so quiet?' The second time I took out a book, the counselor(辅导员) came to see me. She told me to remember the camp spirit and that it was important to be outgoing."

    At work, extroverts often do well. At job interviews, it is usually good to appear extrovert. It suggests that you will be good at the job. But it is wrong to think that only extroverts are good leaders. Introverts work in different ways to extroverts, but they can still do really great things. Darwin, for example, was a quiet, family man. He often took long walks so that he could think clearly. But Darwin's ideas about evolution were revolutionary.

    Introverts must understand that it is perfectly okay to be the way they are. It is not necessary to want to be the center of attention. You don't have to take part in noisy, social activities if you don't want to. And it is not necessary to try to become more outgoing.

    You're sitting on the sofa, and there's your dog, right at your feet. You stand up? He stands up. But then you head to the bathroom, and guess who comes with? Why, your dog, of course. But why? Why does your dog follow you like a shadow, no matter where you go?

    Ever get the feeling you're being followed? As for why your companion follows you everywhere you go, read on!

    "When dogs follow their owners, there can be several scientific explanations, depending on the dog and the individual situation," according to Mary Burch, Ph.D., an animal behaviorist(行为学家).

    These explanations include:

    Positive reinforcement(正面强化): When your dog follows you, good things happen. Think dog food, a hot bath and taking a walk around the neighborhood. Your dog's no dummy. And one of his many talents is learning from experience, that is "reinforcement."

    Natural instinct(本能) to be part of a pack: In fact, a study out of Princeton University that was published in the journal, Science Advances, shows that your dog's drive (驱动力)to follow you around (as well as watch you attentively and seek physical contact (身体接触) from you) lies in his genes(基因).

    Feel good chemicals(化学物质): Your presence causes your dog's brain to release "feel good" chemicals, Dr. Primm explains, citing this study. Considering how much we as humans enjoy those feel-good chemicals, it's no surprise your dog likes them too—and will follow you around to get some!

    Sense of responsibility : As you move about your home, your dog might feel that you are patrolling your territory (巡视领地) and take on the duty to assist you.

We all love to take photographs. It's a simple way to snap a special moment, an amazing view, or just to show off your artistic skills. And it's great to look back through your photo albums and share memories with your friends. In fact, they show a snapshot (快照)in time. This hasn't really changed since the invention of photography in the 1830s. But one thing that has changed is the equipment we use.

For many years, we have used traditional cameras to take our pictures with. Our images were taken onto camera film which was then processed into negatives from which photos were printed— a lengthy process. And we've had a range of cameras to choose from— from the simple compact camera to more advanced single lens reflex, or SLR cameras.

But the biggest change has come with the development of digital devices. This has made taking photo quicker and easier. It's enabled us to take a snap and review our pictures instantly. We've been able to deal with them in post-production, using software on our computer. And of course, we've been able to share them like never before— particularly on social media.

Of course, now we have the smartphone— a phone that is, well, smart because it can take photos and sometimes very good quality ones, and we can share them easily. So does that mean the traditional camera will eventually become outdated? Figures from Japan show how the market is shrinking: shipments of compact digital cameras from companies like Olympus, Canon and Nikon were down 39 percent year on year.

But Phil Hall, editor of Tech Radar magazine, told the BBC that while people are swapping their compact cameras for smartphones, "manufacturers are looking at the more higher-end cameras, high-end compacts, DSLRs, which are the ones you can attach lenses to, mirrorless cameras. In this sense, there's nothing to worry about. "
