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.

    The new study shows that we spend more time using the mobile Internet reading newspapers or magazines or doing some other things. According to the European Interactive Advertising Association(EIAA), the average European spends 4.8 hours reading newspapers and magazines but 1.6 hours more using the mobile Internet a week.

    The EIAA questioned 15,000 people in 15 European countries, looking at how people are using the Internet and its influence on their everyday lives. It found that the mobile Internet is increasingly finding its way into the public awareness. Over 71 million Europeans now have Internet access on their mobile phones. In the UK, 10 million people now access the Internet through their mobile phones and spend 6.3 hours doing so in a week.

    Unsurprisingly, younger generations in the UK are leading the way, with nearly half of the country's 16-to 24-year-olds and a quarter of 25- to 34-year-olds using the Internet, spending 6.5 and 6.2 hours online each week.

     Entertainment plays a main role in our mobile Internet lives, with one in five British people using their phones for online games, a third listening to the online radio and 39 percent watching films, TV or other videos at least once a week. One third of those using an Internet phone said they received videos, images or other multimedia on their mobile, and 61 percent said they passed on contents they received.

    From a communication point of view, 80 percent of those questioned agreed that the Internet had made it easier for them to stay in touch with friends and family.

    Alison Fennah, director of the EIAA, said the mobile Internet use had come to the point that marketers should be looking to develop strategies (策略) that connect with consumers more effectively. “Better devices as well as improved consumer motivation that start coming together in 2011 can make a great difference to extending the online experience.” Fennah said.

    Very few people enjoy going to the dentist, especially for a filling. Often fillings need to be replaced during the patients' lifetime. But is filling the cavity (蛀洞)with a foreign material really the best treatment? What if the tooth could repair itself with its own material–dentine(齿质)? Researchers at King's College London have found a process that may replace the traditional method.

    Paul Sharpe of King's College says a new treatment for cavities is simpler. It uses a drug that causes the tooth to fill in the hole naturally with dentine. "It involves putting a drug in the hole. It excites a natural process, which starts to occur anyway following the damage, so you can actually get the big hole repaired and the repair is a production of the natural material, the dentine."

    Usually a new drug requires repeated testing before it is approved for treatment. However, this drug that produces the re-growth in teeth has already been approved. It is a drug used to treat Alzheimer's disease and other disorders of the nervous system. Researchers explain that they use only a small amount and they use it locally. Usually that means the medicine is put directly on the affected area. It does not travel through the patient's blood.

    Nigel Carter heads Britain's Oral Health Foundation. He describes the new treatment as an exciting possibility for dental care. But Carter also has a warning. "Actually re-growing the tooth that has been lost with a cavity would be really a huge step forward. But, it's also important that we remember that we shouldn't be getting the cavity in the first place. We're talking about a totally preventable disease."

    There are some differences between American English and British English. Some differences are quite interesting.

    When my friend Lily from London used the word “larder”, I didn't know what it meant. Realizing I didn't follow her, she used another word. I finally knew she wanted to find something to keep some food. The next word came up when we were planning a lunch date. She jotted down the date and time in her diary, while I marked my calendar. If she called me on the phone, she would ring me up. But if the line was busy, she would say the line was engaged.

    Most times, I can know what Lily means. Last week, she regretted sending her boys to watch an early morning tennis game without their fleeces. I thought that she meant without their jackets or something like those. Other times, we have to ask each other. She recently told me a funny tale about a woman who was pissed. I wondered what had made the lady angry. It turns out that pissed means drunk.

    Here is one more example. My British friend Jane was filling out a ticket at the grocery store recently. She asked the young man if he had a rubber. When she noticed he didn't follow her, she quickly asked for an eraser, which, in England, is often called a rubber.

    In order to communicate well with the British, we Americans should learn some words that the British use differently. And I think people who learn English as a second language should also realize that there are differences between American English and British English.

    Something very strange and mysterious was going on in Sesemann's house. Every morning, when the servants went downstairs, they found the front door wide open. During the first few days that this happened, every room and corner was searched in great alarm to see if anything had been stolen, but not a thing in the house had been touched. The door was doubly locked at night, and for further security the wooden bar was fastened across it; but it was no good – next morning the door again stood open. One servant even claimed he had seen a white figure standing at the top of the steps and then all in a minute it disappeared.

    Mr. Sesemann told his old friend, a doctor, what had happened in his house. That evening they decided to wait for the ghost. One o'clock struck. There was not a sound. Suddenly the doctor lifted his finger. "Hush! Don't you hear something?" They both listened, and they distinctly heard the bar softly pushed aside and then the key turned in the lock and the door opened. They stepped into the hall.

    "Who is there?" thundered the doctor in a voice that echoed through the hall, as the two men advanced with lights and weapons towards the figure. It turned and gave a low cry. There stood Heidi, with bare feet, staring with wild eyes and trembling from head to foot. The two men looked at one another in surprise. "Child, why did you come down here?" said Sesemann. White with terror, and hardly able to make her voice heard, Heidi answered, "I don't know." The doctor gently took the child by the hand upstairs.

    Then the doctor sat down besides her and asked her some questions in a kind voice. Later he went downstairs. "Sesemann," he said, "let me first tell you that the child is a sleep-walker; secondly, the child is consumed with homesickness. Something must be done at once."
