Your next Saturday night takeaway could be brought to you by a robot after a major food delivery company announced plans to use automated vehicles to transport meals. Europe's biggest online takeaway food company Just Eat has partnered with Starship Technologies to deliver food with robots on the streets of London later this month. “Nobody has ever done deliveries with land-based robots,” said Allan Martinson, the chief operating officer of Starship.

    The robot courier can travel up to 4 miles per hour for about 10 miles. It uses a GPS signal and nine cameras to navigate(确定方向). Instead of a person arriving at their door, customers could find themselves receiving a notification(通知) on their phone that says a robot is on its way and a code to unlock the automated courier. “Put the code in, the robot opens up, and there's your food,” said David Buttress, chief manager of Just Eat.

    The robot, which has so far been tested in Greenwich, Milton Keynes and Glastonbury, costs ￡1 to transport within 3 miles, compared with the ￡3 to ￡6 it costs for a human courier. To date 30 robots have driven nearly 5,000 miles without getting into an accident or finding themselves picked on by passers-by. They have driven in more than 40 cities around the world, including London and Tallinn, Estonia.

    An initial worry was how the public would react to robots. But Martinson said the public has been calm when passing the delivery machine on the streets. “The most surprising reaction has been the lack of reaction,” said Martinson.

    Another significant fear was that people would disrupt(扰乱) the robots, or try to steal them and their contents. To prevent this, the robot is fitted with nine cameras, two way audio, and movement sensors that send a warning if it is lifted off the ground. And it opens only with a pass code provided to the customer via a notification. “It's much easier to shoplift than it is to steal a robot,” said Martinson.

    Chuck McCarthy originally considered becoming a dog walker to earn some extra cash, but soon realized that the job required more than walking dogs on a leash. However, walking people didn't require much when they were out on walks. Chuck realized there was money to be made if he walked people around Los Angeles instead.

    It might sound like a joke, but The People Walker, as he calls himself, is very serious about his new job. For $7 per mile, he offers to walk with clients around L.A., listening to their problems or simply making conversations and offering them a sense of security. At 6-feet, 2-inches, and sporting a bulky figure and bushy beard, Chuck doesn't look like the kind of guy you'd want to mess with.

    Chuck's services are aimed at people who need a motivational boost to go walking, those who don't feel safe walking alone in some areas, and those who are afraid that people might see them walking by themselves and think that they have no friends. "I wear my The People Walker shirt upon request and on the first walk with a new client, so they can be 100% sure it's me," McCarthy says. However, he admits some people are a bit uncomfortable with this policy, as they don't necessarily want everyone to know that they're being walked.

    So far, Chuck McCarthy has already had another five people walkers employed, covering various areas, like downtown L.A., Hollywood, Eagle Rock, or Fairfax. Once he posted signs around the city, his phone started ringing and clients began rolling in. And with all the free publicity he has been getting in the press lately, more requests are coming.

    While he hopes that his acting career will pick up soon, in the meantime Chuck is very happy with his people walking business. After all, it's literally a walk in the park and it pays the bills.

    When Boris left school, he could not find a job. He tried hard and he wrote letters to many companies until he could not afford to buy any more stamps. Boris began to lose his confidence, then depressed. Still he went on trying and still he failed. He began to think that he had no future at all.

    “Why don't you start your own business?” one of his uncles told him. “The world is a money-locker. You'd better find a way of opening it.”

    “But what can I do?”

    “Get out and have a look round.” advised his uncle. “See what people want; then give it to them, and they will pay for it.”

    Boris began to cycle around the town and found a suitable piece of waste ground in the end. Then he set up his business as a cycle repairer. He worked hard, made friends with his customers and gradually managed to win his good fame. A few months later, he found that he had more work than he could deal with by himself. He found a number of empty shops but they were all no good: in the wrong position, too expensive or with some other problems. But at long last, he managed to find an empty shop in a new place where there were plenty of customers but no competition.

    Boris and his assistant taught themselves how to repair motor-cycles. Slowly but surely the profits increased and the business developed. At last, Boris had managed to open the money-locker and found bank notes and gold coins inside.

    It is 2018; e-books are loved by many people. Do you read them?

    An e-book is an electronic book, which can be made from common books and loaded onto an e-reader. The e-reader is a mini-device, just like a cell-phone. It has a touch pad screen and can hold a few hundred e-books. People can read e-books on it just like they do a book. So it is possible for people to read anywhere with an e-reader. This is perfect news for people who love to read books but can't carry many.

    Another great thing is that people can read books on it quickly and there's no need for two hands to hold the book and turn pages. Most e-readers also have a nightlight, so you can read at night and don't wake your partner with a big light on.

    Not all book authors agree to make their books into e-books. The creator of Harry Potter says that her books will never be e-books. However, lots of authors absolutely love the idea and feel it's the next step to keep books alive.

    Nowadays e-books are sold in many websites, from where you can buy and load them onto your e-reader. Those websites look just like ordinary online bookstores and have a list of best sellers and a new book section. There is also a clear price on each e-book to make sure people can buy them like buying common books.

    No one knew Prince Edward Street as well as Pierre Dupin. He had delivered milk to the families on the street for thirty years. For the past fifteen years a large white horse named Joseph pulled his milk wagon. Joseph was a gentle horse with beautiful spirit shining out of its eyes, so Pierre named him after Saint Joseph.

    Every morning at five, Pierre arrived at the milk company's stables to find Joseph waiting for him, Pierre would call, “Good morning, my old friend.”, as he climbed into his seat, while Joseph turned his head toward the driver. And the two would go proudly down the street. Without any order from Pierre, the wagon would roll down three streets. Then it turned right for two streets, before turning left to Saint Catherine Street. The horse finally stopped at the first house on Prince Edward Street. There, Joseph would wait perhaps thirty seconds for Pierre to get down off his seat and put a bottle of milk at the front door.

    Pierre knew every one of the forty families that got milk. The cooks knew that Pierre could not read or write; so, instead of leaving orders in an empty milk bottle, they simply sang out if they needed an extra bottle.

    Pierre also had a wonderful memory. When he arrived at the stable he always remembered to tell Jacques, the foreman(领班) of the stables, “The Pacquins took an extra bottle this morning; the Lemoines bought a pint of cream …” Most of the drivers had to make out the weekly bills and collect the money. But Jacques, liking Pierre, never asked him to do this.

    One day the president of the milk company came to inspect the early morning milk deliveries. Jacques pointed to Pierre and said: ”See how the horse listens and how he turns his head toward Pierre? See the look in that horse's eyes? You know, I think those two share a secret. I have often felt it. He is getting old. Maybe he ought to be given a rest, and a small pension.”

    “But of course,” the president laughed. “He has been on this job now for thirty years. All who know him love him. Tell him it is time he rested. He will get his pay every week as before.”

    But Pierre refused to leave his job. He said his life would be nothing if he could not drive Joseph every day. “We are two old men,” he said to Jacques. “Let us wear out together. When Joseph is ready to leave, then I too will do so.”

    Then one cold morning Jacques had terrible news for Pierre. Jacques said, ”Pierre, your horse, Joseph, didn't wake up. He was very old, Pierre.” Jacques said softly. “He is over in his stall, looking very peaceful. Go over and see him.” Pierre took one step forward, then turned. “No ... no ... I cannot see Joseph again. You ..., you don't understand, Jacques.”

    For years Pierre had worn a large heavy cap that came down low over his eyes. It kept out the bitter cold wind. Now, Jacques looked into Pierre's eyes and he saw something that shocked him. He saw a dead, lifeless look in them.

    “Take the day off, Pierre,” Jacques said. Pierre walked to the corner and stepped into the street. There was a warning shout from the driver of a big truck ... there was the screech(尖锐的刹车声) of rubber tires as the truck tried to stop. But Pierre heard nothing.

    Five minutes later a doctor said, “He's dead ..., killed instantly.”

    “I couldn't help it,” the truck driver said. “He walked in front of my truck. He never saw it, I guess. Why, he walked as though he were blind.”

    The doctor bent down. “Blind？Of course, this man has been blind for five years.”  He turned to Jacques, “Didn't you know he was blind？”

    “No ...no ...” Jacques said softly. “None of us knew. Only one ... only one knew－a friend of his, named Joseph ... It was a secret, I think, just between those two.”

    Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, overhunting and the ivory trade were the biggest threats to elephants' survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation — land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local famers to improve their life in order to encourage them to protect rather than destroy elephants.
