Some time ago, I discovered a whole lot of antique(古董) shops near my home. So I left home one morning carrying the char that had a broken leg. I didn't think there would be any difficulty in getting it mended. I went into the first shop expecting a friendly reception. I was quite wrong. The man wouldn't even look at my chair.

    The second shop, although slightly more polite, was just the same, and the third and the fourth — so I thought that my approach must be wrong.

    I went into the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, “Would you like to buy a chair?” He looked it over carefully and said, “Yes. How much do you want do it, sir?” “Twenty pounds,” I said. “Ok,” he said, “I'll give you twenty pounds.” “It has a slightly broken leg,” I said. “Yes, I saw that; it's nothing.”

    Everything was going according to the plan and I was getting excited. “What will you do with it?” I asked. “Oh, it will be easy to sell once the repair is done.” “I'll buy it,” I said. “What do you mean? You've just sold it to me.” he said. “Yes, I know but I've changed my mind. I'm sorry. I'll give you twenty-seven pounds for it.” “You must be crazy,” he said. Then, suddenly the penny dropped. “I know what you want. You want me to repair your chair.” “You're right.” I said. “And what would you have done if I had walked in and said, ‘Would you mend this chair for me?'” “I wouldn't have agreed to do it,” he said. “We don't do repairs, not enough in it and too much trouble. But I'll mend this for you, shall we say for five pounds?” He was a very nice man and was greatly amused by the whole thing.

    Letters as a way of communication have long given way to phone calls and WeChat messages.

    But a TV show, Letters Alive, is helping bring this old way to keep in touch back into the present.

    Letters Alive took its idea from a UK program with a similar name, Letters Live, which was first shown in 2013. Both shows feature famous actors and actresses, but there is no gossip , no eye-catching visual effects or any regular showbiz (演艺圈) activities. Instead, it's just one person walking up to a microphone and reading a letter.

    But these are not just any letters. They are selected from a wide time span and a diverse range of subjects. There is, for example, a passionate letter that famous painter Huang Yongyu wrote to playwright Cao Yu 30 years ago to criticize his lack of creativity. There is also a heartfelt note from Spring and Autumn Period written by two ordinary young soldiers to their elder brother to report their lives in the war zone.

    Every letter is like a small piece of history. By hearing them being read, it's as if we are being sent back in time to experience a moment that we would otherwise never have had the chance to.

    “Letters Live makes us pause and imagine the lives behind the letters,” UK actor Benedict Cumberbatch, one of the readers on the UK show, told The Guardian. “It allows people from all ages and all walks of life to experience a moment of time in someone else's life for a brief moment.”

    Compared to published texts, letters also come with a personal touch.

    One example from Letters Live was a note of thanks from the mother of a dying child to JK Rowling, author of the Harry Potter books. It read: “Mrs Rowling, Cancer threatened to take everything from my daughter, and your books turned out to be the castle we so desperately needed to hide in.”

    According to Guan Zhengwen, the director of Letters Alive, it is this kind of humanity behind every letter that strikes a chord (引发共鸣) with the audience. It is also what made the show a big hit in China ever since its first episode aired on Dec 5.

    “It's a thing of the past that entertainment shows establish themselves only with pretty faces,” Guan told Sohu News. “Showbiz is starting to switch to a focus on wisdom and intelligence.

    A golf tournament (锦标赛) isn't held every day and thus, as an organizer, you have to put on a great show for those who wait for it.

    Preparations before the Tournament

    An important thing you need to note down at this stage here is that once you start advertising an event, the event has actually begun for the audience. At this stage, you need to decide what you are going to call this event. You should make the name and the advertisement special, so that people will give them a second look. Depending on your economic situation, you need to decide whether you want to hold this event for amateurs or for experts. The next thing is to choose a proper place to hold the tournament.

    Plan of Action during the Event

    While the players are on court, you have to make sure that everything they might need is made available to them. Since golf is a sport that is played in the open, guests should be given drinks from time to time, preferably a drink of their choice. There should also be enough dustbins to keep the court clean. The things the guests need, from extra equipment to drinks, should not be put off for any reason. Announcement of some contests, lucky draws and prizes during the event will add to the entertainment of the tournament. Another one of the successful golf tournament ideas is an auction (拍卖) of some particular things during the game. You can get some equipment signed from the players.

    Post Tournament Necessities

    Now that the tournament is over, you need to keep a small after-party in the form of a dinner. During this party, the guests can actually communicate with the players and congratulate those who won.

    Daniel stays home on workdays. He starts his personal computer in order to connect with the office which is about three hundred miles away in another city. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Daniel doesn't talk to any other human beings, and he doesn't see any people except the ones on television. Daniel is imaginary, but his lifestyle is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.

    The world of business is one area in which technology is separating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals (终端) in their own homes. They would never have to actually see the people they're dealing with. In addition, the way employees are paid will change. Workers' salaries will be automatically paid into their bank accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts. Many companies and consumers have already changed the way they sell or buy products. E-commerce, or business done on the Internet, is becoming more and more popular. This, therefore, makes it possible for people to do shopping without going out of their homes.

    Another area that technology is changing is entertainment. Music for example, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living-rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing as well. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living-rooms.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件)," said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. "The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own," he said.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to," said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. "You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead," he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis."

    The Internet has completely changed the workplace over the past three decades. Artificial Intelligence is now all set to do the same, and businesses that don't take advantage of the technology risk being left behind.

    Global tech giants (巨头) like Amazon have been leading the change, and businesses of all sizes are now using the technology for employing and managing their staff.

    Among them is L'Oreal. With about a million applicants for roughly 15,000 new positions each year, the company is using AI to hire.

    “We really wanted to save time and focus more on quality, diversity and candidate experience. And AI solutions were the best way to go faster on these challenges, said Eva Azoulay, global vice-president of L'Oreal's Human Resources Department.

    The company uses Mya, a chatbot, to save employers' time during the first stage of the process. It handles routine questions from candidates, and checks details such as availability and visa requirements. Should candidates make it to the next round, they'll run into Seedlink, an AI software that scores applicants based on their answers to open-ended interview questions. These scores don't replace human judgment, said Azoulay, but they do pick out candidates who might not seem like obvious choices.

    Early results have been promising. For one internship program, where 12,000 people apply for about 80 spots, employers claim they saved 200 hours of time while hiring the most diverse group to date.

    Other businesses have gone beyond employment and are using AI to help manage employees. Some UK firms have started using Isaak, a system designed by the London-based company StatusToday, to track how many hours staff spend online and the number of emails they receive. London real estate agent JBrown has been using this system since March. CEO James Brown said it helps the firm understand employees' habits and prevent them from overworking. "It enables us to solve bottleneck problems and relieve overburdened employees," he said.

    Despite these examples of good practice, there is still a long way for AI to reach its full potential (潜力), and the technology comes with risks. Another AI danger could be its impact on jobs through automation (自动化). McKinsey predicts AI could add $13 trillion to the global economy by 2030, with early adopters doubling their cash flow over that period. But the demand for repetitive (重复的) or digitally-unskilled jobs could drop by around 10%, the consulting firm said in a 2018 report.
