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.

    It was an oral English class and in front of us was standing our teacher Lila Betray, who was a university student from the US. Somehow we came to the point whether any of us could sing an English pop song in front of the class. You know, maybe three or more out of ten Chinese students are shy in class. As a result, there was silence in class for quite a while, which made everybody feel rather embarrassed(尴尬的), including the teacher.

    I was a shy boy. However, just at that moment, a great idea struck me suddenly."Seize the enjoyment! Seize the opportunity. Yes, there couldn't be a better opportunity." I said to myself. "Why not seize it? Why should I have always to be the guy regretting missing the opportunity just because of shyness? Yes, maybe I should have a try!"

    So, I raised my hand. And I remember that it took me quite a while to think what the song's name was. Though I sang no more than five sentences because of forgetting the lyrics(歌词), their clapping hands told me that I did the job well. Later, I got a gift and I was really happy.

    I think that is one of the most unforgettable moments in my life. Through this experience, I've also got to know that we should believe that we can do the job well, no matter how difficult it seems for us. Just have a little more courage.

    After years of debate, gray wolves were reintroduced (重新引进) to Yellowstone National Park. Fourteen wolves were caught in Canada and moved to the park. By 2016, the Yellowstone wolf population had grown to more than 170.

    Gray wolves once were seen here and there in the Yellowstone area and other pans of United States, but they were gradually displaced by human development. By the 1920s, wolves had disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around. The disappearance of the wolves had many unexpected results. Deer and elk populations—major food sources(来源) for the wolf—grew rapidly. These animals ate large amounts of plants, which reduced plant diversity(多样性) in the park. With the disappearance of gray wolves, coyote (草原狼) populations also grew quickly. The coyotes killed a great number of red foxes in the park, and completely drove away the park's beavers (河狸).

    As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many framers were against the plan because they feared that wolves would kill their farm animals or pets.

    The government spent nearly 30 years thinking lip a plan to reintroduce the wolves. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

    Teens don't understand the big fuss (小题大做). As the first generation to grow up in a wired world they hardly know a time when computers weren't around, and they eagerly catch the chance to spend hours online, chatting with friends, so what?

    But researchers nationwide are increasingly worried that teens are becoming isolated, less skillful at person-to-per son relationships, and perhaps numb to the cheatings that are so much a part of the e-mail world. "And a teen's sense of self and values may be changed in a world where personal connections can be limitless," said Shetty Turkle.

    Another researcher, Robert Kraut, said he's worried about the "opportunity costs" of so much online time for youths. He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. "Chatting online may be better than watching television, but it's worse than hanging out with real friends," he said.

    Today's teens, however, don't see anything strange in the fact that the computer takes up a central place in their social lives. "School is busy and full of pressure. There's almost no time to just hang out," said Parker Rice, 17 "Talking online is just to catch time."

    Teens say they feel good about what they say online or taking the lime to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don't want to do so. But they insist there's no harm.

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures stress the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries, like the UK or France, people find it easier to build up a lasting working relationship at restaurants or cafe rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion, instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values, however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

    It's a common belief that the roles actors play might somehow reflect their true personalities. It's usually not true, but British actress Phoebe Waller-Bridge, 34, is an exception.

    Just like Fleabag, the character she played in the comedy-drama series of the same name, Waller-Bridge feels that her life is a mess. "It's just really wonderful to know that a dirty and messed up woman can make it to the Emmys," she said. She may be "messed up", but Variety magazine calls her an "all-around icon".

    Last month, Waller-Bridge took home three Emmy awards for her work on Fleabag — best writing in a comedy series, best lead actress, and best comedy series.

    Her success is partly because of her family. Waller-Bridge was brought up in a free environment. Her mother always told her, "You can be whatever you want if you imagine it." So Waller-Bridge broke all the rules about what a "good" girl should do. "Our laws and moral codes don't apply — she lives without fear of consequence," The Sun noted.

    That fearlessness extends to being authentic (真实的) in her writing and acting. Unlike the can-do heroines and strong, successful women in many TV dramas, Waller-Bridge shows a flawed but real character. The character Fleabag was a screw-up who always found a way to say or do the wrong thing. "It resonated with the lives of stressed-out women everywhere in reality — doing their best to find balance in their lives," a viewer wrote on US movie website.

    Villanelle in Killing Eve, another hit TV series developed by Waller-Bridge, was a little bit violent but showed no interest for the rules others created, which make many people see themselves in her.

    "People have been scared to write characters like these. But I think, now, women are so relieved to have this new template (样板). And, aren't we all a bit of everything?" Waller-Bridge said in an interview with Indian Express.

    With such courage and sincerity, Waller-Bridge is, without a doubt, a "golden girl" in Hollywood, Australian news website The New Daily commented.
