For most city people, the elevator is an unremarkable machine that inspires none of the enthusiasm or interest that Americans afford trains, jets，and even bicycles. Dr. Christopher Wilk is a member of a small group of elevator experts who consider this a misunderstanding. Without the elevator, they point out, there could be no downtown skyscrapers or tall buildings, and city life as we know it would be impossible. In that sense, they argue，the elevator's role in American history has been no less significant than that of cars. In fact, according to Wilk_? the car and the elevator have been locked in a “secret war” for over a century, with cars making it possible for people to spread horizontally (水平地)，and elevators pushing them toward life in close groups of towering vertical (垂直的)columns.

    If we tend to ignore the significance of elevators, it might be because riding in them tends to be such a brief, boring, and even awkward experience^one that can involve unexpectedly meeting people with whom we have nothing in common, and an unpleasant awareness of the fact that we're hanging from a cable in a long passage.

    In a new book, Lifted, German journalist and cultural studies professor Andreas Bernard directed all his attention to this experience, studying the origins of elevator and its relationship to humankind and finding that riding in an elevator has never been a totally comfortable experience. “After 150 years, we are still not used to it”， Bernard said. “We still have not exactly learned to cope with the mixture of closeness and displeasure.” That mixture, according to Bernard, sets the elevator ride apart from just about every other situation we find ourselves in as we go about our lives.

    Today，as the world's urban population explodes，and cities become more crowded, taller, and more crowded, America's total number of elevators—900,000 at last count, according to Elevator World magazine's “2012 Vertical Transportation Industry”一are a force that's becoming more important than ever. And for the people who really, really love them, it seems like high time that we looked seriously at just what kind of force they are.

    Children who often move house are more likely to suffer poor health, research suggests. Moving several times before the age of 18 can affect the health, psychological distress and increase the chance that a child may use illegal drugs.

    The study included information for 850 people, followed-up for a period of 20 years. Scientists found changing home several times could cause psychological distress in children.

    By the age of 18, 59 percent had moved house once or twice while one in five had moved at least three times. Some 20 percent had stayed in the same house during their childhood.

    Children of single parents or those with step-parents were more likely to move home, as were those with two or three brothers or sisters. Those with four or more brothers and sisters were more likely to stay in the same house.

    Experts found that people who moved at least once had an increased risk of poor health, some of this could be because of changing schools. Those who had moved three times or more were three times as likely to have had suicidal thoughts as those who stayed in the same house.

    Dr Denise Brown said, “For many people, moving house is a good experience as it may lead to improved family conditions. But for some family members, especially children, moving can be bad and may lead to poor health outcomes and behaviors in adulthood. The bad effect on health in adulthood appears to be somewhat accounted for by a high number of school moves.”

    When was the last time you used plastic plates? Next time, why not try some edible ones? You'll help the environment and your guests won't go hungry. "I used to work in school catering and saw a lot of money being thrown away. I thought that was criminal, so I decided to do something about it," said Italian school chef Tiziano Vicentini.

    Now, Vicentini has an amazing range of edible plates for schools. The plates are made out of bread dough, so you can eat them afterwards. "These dishes cost a few pennies each and are either eaten by the kids, or go into recycling bins for animal food," explained Vicentini, 50, of Milan. But now other companies are developing edible plates, too. The Edible-Plate Company offers edible plates, bowls, trays and cups. Their products are environmentally-friendly, 100% biodegradable and can be used for all types of catering and home use. And they're made from a natural plant. After use, they can be fed to animals or left to degrade naturally.

    They also have a range of cutlery（餐具） made from corn and potato starch（淀粉）. These plates will also help reduce the amount of plastic; we create. Waste from plastic causes a lot of damage to the environment, as well as costing governments millions m waste management. Plastic bags often end up in landfill sites or on the street. And the burning of plastic waste causes toxic gases that pollute the air. In response to this, governments around the world are introducing tough recycling regulations. And many shops are offering biodegradable plastic bags and eco-safe packaging on their products. To help matters, the International Organization for Standardization (the ISO) has also developed a system to evaluate the biodegradability of products, with a certification and logo scheme, Meanwhile, how about a nice plate for lunch?

    A bicycle may be seen by most people as just another vehicle (交通工具), but for many Londoners, cycling is a way of life. According to an official UK government survey in 2017, about 570,000 bike journeys are made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.

    London introduced a public bike-sharing system in 2010. "There can be no doubt that our trusty bicycles have changed the way people get around our great city," Johnson told the Guardian in 2015.

    In London, bikes are used for more than just taking short trips to and from the subway. No matter where you want to go in the city, taking a bike is usually the quickest and easiest choice.

    And it's not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government's Cycle to Work scheme (骑行倡议) allows employees to buy a brand new bike without having to pay any tax (税). This means that it's common to see many people cycling to and from work, and some employers even provide workplace showers and lockers (储物柜) for their workers. More importantly, a cycle-friendly boss may let you off for being late if you rode a bike to work.

    Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic Magazine, "Bike riding can improve people's happiness."

    The first organized system for sending messages began in Egypt around 1500 B.C. This system developed because the pharaohs frequently needed to send messages up and down the Nile River in order to keep their empire running smoothly. Later, the Persians developed a more efficient system for sending messages using men and horses. Messages carriers rode along the road system stretching from one end of the Persian Empire to the other. Along these roads, fresh men and horses waited at special stations to take and pass along any messages that needed to be sent. The stations where riders passed messages back and forth were built 23 kilometers apart, so the men and horses were able to travel quickly between them. The Romans later took up his idea and improved it by using a more advanced and extensive road system.

    In China, however, Kublai Khan had built up his own system for delivering messages. This system worked in the same basic way as the Roman system. The difference was that Kublai Khan kept 300,000 horses along the roads of this delivery lines. There were over 10,000 stations where a message would be passed from one rider to another with a fresh horse. In this way, Kublai Khan could receive messages from anywhere in the country in only a few days.

    It was not until the 1500s that a well-organized postal system appeared again in Europe. One family, the von Taxis family, gained the right to deliver mail for the Holy Roman Empire and parts of Spain. This family continued to carry mail, both government and private, throughout Europe for almost 300 years.

    In 1653, a Frenchman, Renouard de Velayer, established a system for delivering post in Paris. Postal charges at that time were paid by the recipient, but de Velayer's system was unique by allowing the sender to pre-pay the charges, in a similar way to the modern stamp. Unfortunately, de Velayer's system came to an end when jealous competitors put live mice in his letter boxes, ruining his business. Eventually, government-controlled postal systems took over from private postal businesses, and by the 1700s government ownership of most postal systems in Europe was an accepted fact of life.

    The thing that all these early systems had in common was that they were quite expensive for public use, and were intended for use by the government and the wealthy. However, in 1840, a British schoolteacher named Roland Hill suggested introducing postage stamps, and a postal rate based on weight. This resulted in lowering postal rates, encouraging more people to use the system to stay in touch with each other, His idea helped the British postal system begin to earn profits as early as 1850. Soon after that many other countries took up Mr. Hill's idea. And letter writing became accessible to anyone who could write. Today, the Roland Hill awards are given each year to "encourage and reward fresh ideas which help promote philately"(stamp collecting).
