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 . Instead of a person arriving at their door, customers could find themselves receiving a notification 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 PS1 to transport within 3 miles, compared with the PS3 to PS6 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 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. Which of the following is one of the worries about Starship robots? A) People's indifference to the robots. B) Safety of the robot delivery. C) Accuracy of the robot delivery. D) People's concern about public traffic.

When I am feeling down, I listen to uplifting music to lift my spirits. When I want to calm down, I listen to Indian classical instrumental music. Many times, I look at contemporary Indian art - either in real art galleries or in virtual art galleries on the Web to improve my mood. I particularly like the paintings with vibrant colors or ones which present a calm landscape using gentle colors. Art therapy uses the creation or viewing of art to help people discover and express their feelings. Unlike art for art's sake, which focuses on the finished piece, art therapy focuses on the process of creation itself. Art therapists believe that the act of making a piece of art _ internal activity that contributes to physical, emotional and spiritual healing. For people who are not able or ready to create art, going to an art museum or looking through art books or virtual art galleries can also be helpful. Simply viewing art refreshes the spirit and promotes relaxation. Art therapy is helpful in healing in various ways. The aesthetic quality of the work produced can lift a person's mood, boost self-awareness, improve self-esteem and increase self-confidence. Also, research shows that physiological functions, such as heart rate, blood pressure, and respiration , become slow when people are deeply involved in an activity they enjoy. Because art therapy uses a language other than words, it is often employed in treating patients with physical or emotional illnesses who have difficulty talking about their fears or hopes, or about their anger and other strong emotions. The creation of art helps people get in touch with thoughts and feelings that are often hidden from the conscious mind. Stress reduction is also a significant benefit. Studies have shown that repressing strong feelings can lead to a buildup of stress, and that stress can intensify pain and the symptoms of various diseases.

Question: There used to be four common life phases : childhood, adolescence, adulthood and old age.Now, there are at least six: childhood, adolescence, odyssey, adulthood, active retirement and old age.Of the new ones, the least understood is odyssey, the decade of wandering that frequently occurs between adolescence and adulthood. They see that people in this age bracket are delaying marriage.They're delaying having children.They're delaying permanent employment.People who were born before 1964 tend to define adulthood by certain achievements moving away from home, becoming financially independent, getting married and starting a family. In 1960, roughly 70 percent of 30-year-olds had achieved these things.By 2000, fewer than 40 percent of 30-year-olds had done the same. Yet with a little imagination it's possible even for baby boomers to understand what it's like to be in the middle of the odyssey years.It's possible to see that this period is a sensible response to modern conditions. Two of the American best social scientists have been trying to understand this new life period.Through their work, you can see uncertainty that now characterizes this stage.Young people grow up in tightly structured childhoods, Robert Wuthnow of Princeton observes, but then graduate into a world of uncertainty.Old success recipes don't apply, new systems have not been established and everything seems to give way to a less permanent version of itself.Dating gives way to Facebook and hooking up.Newspaper reading gives way to blogging.For example, in 1970, 49 percent of adults in their 20s read a daily paper, now it's at 21 percent. The job market is changeable.Graduating seniors don't find corporations offering them jobs that will guide them all the way to retirement.Instead they find a vast menu of information economy options, few of which they have heard of or prepared for. By 2000, most of the 30-year-olds _ . A) were financially dependent B) got well-prepared for the employment C) got married early and started their family D) preferred blog writing to newspaper reading
