People can be addicted to different things, e.g. alcohol, drugs, certain foods, or even television. People who have such an addiction are compulsive, i.e they have a very powerful psychological need that they feel they must satisfy. According to psychologists, many people are compulsive spenders; they feel that they must spend money. This compulsion, like most others, is irrational-impossible to explain reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending enormous amounts is actually greater than the pleasures that they get from the things they buy.

    There is even a special psychology of bargain hunting. To save money, of course, most people look for sales, low prices, and discounts. Compulsive bargain hunters, however, often buy things that they don't need just because they are cheap. They want to believe that they are helping their budgets, but they are really playing an exciting game: when they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior: a good reason for the things that they do and the real reason.

    It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies and advertisers use psychology to increase business: they consider people's need for love, power, or influence, their basic values, their beliefs and opinions, and so on in their advertising and sales methods.

    Psychologists often use a method called “behavior therapy” to help individuals solve their personal problems. In the same was, they can help people who feel that they have problems with money.

    Cold weather has a great effect on how our minds and our bodies work. Maybe that is why there are so many expressions that use the word cold. For centuries, the body's blood has been linked closely with the emotions. People who show no human emotions or feelings, for example, are said to be cold –blooded. Cold –blooded people act in merciless ways. They may do cruel things to others, and not by accident. For example, a newspaper says the police are searching for a cold-blooded killer. The killer murdered someone, not in self-defense. He seemed to kill with no emotion.

    Cold can affect other parts of the body, the feet, for example. Heavy socks can warm your feet, if your feet are really cold. But there is an expression—to get cold feet –that has nothing to do with cold or your feet. The expression means being afraid to do something you had decided to do. For example, you agree to be president of an organization. But then you learn that all the other officers have given up the position. All the work of the organization will be your responsibility. You are likely to get cold feet about being president when you understand the situation.

    Cold can also affect your shoulder. You give someone the cold shoulder when you refuse to speak to them. You treat them in a distant, cold way. The expression probably comes from the physical act of turning your back toward someone, instead of speaking to him face-to-face. You may give a cold shoulder to a friend who has not kept a promise he made to you. Or, to someone who has lied about you to others.

    A cold fish is not a fish. It is a person. But it is a person who is unfriendly, unemotional and shows no love or warmth. A cold fish does not offer much of himself to anyone.

    Out in the cold is an expression often heard. It means not getting something that everybody else got. A person might say that everybody but him got a pay raise. He was left out in the cold. And it is not a pleasant place to be.

    The streets of Stockholm may be cold and snowy during winter, but it is one of the world's hottest startup(创业) centers and a good choice for people with talent worldwide.

    Once the snow melts(融化) in early spring, the city is among the greenest in the world. Two thirds of Stockholm is made up of either water or parks, and locals make it the first thing to enjoy these peaceful surroundings. Less than l% of Swedish employees work more than 50 hours per week.

    The quality of life is important. New parents are given 480 days of leave to look after their babies, while childcare is heavily supported in various sides. Little wonder that Sweden was rated the best location in the world for family life. Adam Webb, 34, a British businessman and father-of-one, said, "Everything is set towards helping parents, from giving dads time off on almost full pay to free bus rides for anyone with a baby carriage."

    Stockholm is also proud of what Vogue magazine recently ranked as Europe's coolest neighborhood. On the island of Sodermalm, just south of the city centre, independent record stores still make money, while plenty of cafes offer a taste for Scandinavia's love affairs with timeless style.

    Many major international companies, including H&M and Ericsson, offer expats(外来者) accommodation for the first three months of their contracts(合同) in Stockholm. But other foreigners arriving in the city are left to battle with a unique property market and a shortage of apartments. More than a third of Swedes live in rented housing, half of which is owned by local governments or state rental companies. If you're lucky enough to get a firsthand contract for this kind of accommodation, it is yours for life. Expats are welcome to join the queue, but in Stockholm they will find around half a million locals in front of them and an average wait of nine years.

    "Finding a place to live is the single biggest challenge when moving to Stockholm, but there is a lot going on to try and solve the problem," said Julika Lamberth from Stockholm Business Region, a state-funded company working to increase investment in the city.

    The Renaissance marks a period of human awakening. In this article we are going to explore the inventions during this period which have helped change the life and progress of mankind.

    Clock

    The first mechanical clock was invented in the early 1300's. Galileo, an Italian scientist, discovered the pendulum (钟摆) around 1602. The pendulum greatly improved the movement of the hands of a clock. The average error with the pendulum varied only by seconds each day. Before this the error was from 10 to 15 minutes a day.

    Eyeglasses

    In the late thirteenth century, paintings first appeared with people wearing or holding eyeglasses. From these paintings, we know that eyeglasses were invented in Italy. Around 1300 the Venetian Glassmaker's Guild made it illegal for cheap glasses to be made. By 1352, eyeglasses were only worn by well-educated rich men. In 1456, the invention of the printing press allowed books to become widespread. Once people owned books, reading glasses began to be seen in the hands of common people. In 1623, the Spanish invented the first graded eyeglasses.

    Flush toilet (抽水马桶)

    Sir John Harrington, godson to Queen Elizabeth, made the first flush toilet for himself and his godmother in 1596. He was teased by his friends and never made another one.

    In 1775, Alexander Cummings reinvented the flush toilet more commonly called the water closet. Two years later in 1777, Samuel Prosser applied for and received a patent for it.

    Wallpaper

    In 1496, the first paper factory came into operation in England. English artists soon make wallpaper for decoration. For the next 200 years England was a large producer of wallpaper for Europe. Before wallpaper was invented, only wealthy people could afford to decorate the walls of their houses.

    It is reported that a record-breaking high-speed rail will connect Inner Mongolia in the north to Hainan in the south. According to the Shaanxi Development and Reform Commission, the proposed line will operate at a speed of 350 kilometers per hour(217 mph).

    Beginning in Inner Mongolia's Baotou city and running through southern Shaanxi, Hubei, Hunan, Guangxi and Guangdong, its final stop would be in Haikou city on Hainan Island, China's southernmost province.

    Though the exact length of the proposed route has not been released, it will likely become the world's longest high-speed rail line as the journey by road between Baotou and Haikou is approximately 3, 000 kilometers(1, 864 miles) long. Currently, the world's longest high-speed rail line is almost 2, 300 kilometers long (1, 429 miles), running from Beijing to Guangzhou.

    The proposed rail is part of China's aim to create another "Silk Road of the 21st Century" and improve the country's transportation network while driving land development and urbanization(城市化) in some provincial areas.

    Many of the provinces through which the high-speed trains will travel are near major bodies of water, such as the Yellow River in Inner Mongolia and Shaanxi province, the Yangtzi River in Hubei and the South China Sea, where the line would end. It will also take passengers to popular tourist attractions including Zhangjiajie, Xi'an, Guilin and minority areas in western Hunan and Hubei.

    "The country is now shifting its focus and investing in the western regions and economically underdeveloped areas, making up for China's long debt to these areas, " Tan yuzhi, professor of the School of Economics and Management at Hubei University for Nationalities, told local media. " The project will significantly narrow regional disparities(差异) and solve minority issues."

    However, Deng Hongbing, director of China University of Geosciences' Center for Regional Economic and Investment Center, said that if the north-to-south railway is to go ahead, there needs to be a sound ecological program in place to ensure the protection of these underdeveloped and ecologically sensitive areas.
