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.

    Attention from strangers is nothing new to me. Questions about my height is the center of almost every public interaction. My friends say my height is just a physical quality and not a personality aspect. However, when I reflect on my life, I realize that, my height has shaped my character in many ways and has helped to make me who I am.

    I learned how to be kind. When I was younger, some parents in my neighborhood regarded me kind of dangerous because I was so much larger than other children my age. I had to be extra welcoming and gentle simply to play with other children. Of course, now my coaches wish I weren't quite so kind on the basketball court.

    I learned the quality of not being too proud about myself. At 7 feet tall, everyone expects me to be an amazing basketball player. They come expecting to see Dirk Nowitzki, and instead they might see a performance more like Will Ferrell(successfully starred a professional basketball player). I have learned to be modest and to work even harder than my fellows to meet their (and my) expectations.

    I developed a sense of lightheartedness. When people playfully make fun of my height, 1laugh at myself too. On my first day of high school, a girl dropped her books in a busy hallway. I got down to her level and gathered some of her notebooks. As we both stood up, her eyes widened as I kept rising over her. Astonished, she dropped her books again. Embarrassed, we both laughed and picked up the books a second time.

    All of these lessons have defined me. Looking back, I realize that through years of such experiences, I have become a confident, expressive person. Being a 7-footer is both a blessing and a curse, but in the end, accepting who you are is the first step to happiness.

    Many people in high school cannot wait to go to college and leave their hometown behind. Questions arise, though, when it comes to all of the decisions involved in choosing a college.

    One of the first considerations may be finance. State and public colleges are often the least expensive. Often, though, the better colleges are private and more expensive. It is sad when gifted students cannot attend a college of their choice just for financial reasons.

    Another major factor is location. Whether the college is in a small town or large city can have a major impact on its activities. A water lover probably will be more comfortable spending four years near an ocean or a lake. Those who cannot tolerate heat will probably be more comfortable at a northern college. Distance from home may also come into consideration. If family is a top priority, that person should stay close to home; on the other hand, if independence is desired, a campus farther from home would be more appropriate.

    School size also plays a major role in the decision process. If you want to get to know your teachers, a small college is suitable. For those of you who consider yourself a “people person” and want a wide range of activities, a large college is more fitting. Your area of interest is another factor to consider in the decision-making process if you want to get the most from your education. The whole point of college is to learn what is of interest to you.

    Crucially(至关重要地), one must take into consideration the colleges by which you can realistically be accepted. An Ivy League school for an average student would probably not be a good match. Similarly, an average school for an above-average student would not work well. The college should provide enough of a challenge for the student to work hard. Although there may not be the perfect college out there, there probably will be one that is close. Those who cannot find a suitable college are probably not looking hard enough.

    One night about nine o'clock, Dr. Eyck, a surgeon, had a phone call from Dr. Haydon at the hospital in Clens Falls. The surgeon was asked to go there at once to operate on a very sick boy who shot himself while playing with a gun.

    The doctor was soon on his way to Clens Falls. It was 60 miles away. And it was snowing heavily in the city. The surgeon thought he could get there before 12 o'clock.

    A few minutes later, the doctor was stopped by a man in an old black coat. Gun in hand, the man ordered the doctor to get out. Then the man drove the car down the road, leaving the doctor in the falling snow.

    It was after 2 o'clock in the morning when the doctor arrived at the hospital in Clens Falls. Dr. Haydon told him that the boy had died an hour before.

    The two doctors walked by the door of the hospital waiting room. There sat the man in the old black coat with his head in his hands.

    "Mr. Cuninghan," said Dr. Haydon to the man, "This is Dr. Eyck. He is the surgeon who walked all the way from Albany to save your boy."

    Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce garbage, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bag.

    Americans use more than 100 billion thin plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts (收银台). The bags are not allowed in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring (聘请)scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

    Among the bag makers' arguments: many cities with bans（禁令）still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.

    The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

    Environmentalists don't doubt these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

In order to bring down the number of accident and make drivers aware of the danger of driving much fast, many speed cameras are fixed on the roads. Most of them were placed in bright yellow boxes, so drivers can see it clearly from a distance and slow down. On other hand, some officials have the opposite ideas.They believe hiding cameras are more effective than visible ones. The reason is because drivers, not knowing the exact locations of the cameras, will drive more cautious. The police are now gathered related data to make sure which is good.
