My father's reaction to the bank building at 43rd Street and Fifth Avenue in New York city was immediate and definite: "You won't catch me putting my money in there!" he declared, "Not in that glass box !"

    Of course, my father is a gentleman of the old school, a member of the generation to whom a good deal of modern architecture is upsetting, but I am convinced that his negative response was not so much to the architecture as to a violation of his concept of the nature of money .

    In his generation money was thought of as a real commodity (实物)that could be carried, or stolen. Consequently, to attract the custom of a sensible man, a bank had to have heavy walls, barred windows, and bronze（青铜） doors, to affirm the fact, however untrue, that money would be safe inside. If a building's design made it appear impenetrable（难以渗透的）, the institution（公共机构, 协会, 制度）was necessarily reliable, and the meaning of the heavy wall as an architecture symbol dwelt in the prevailing attitude toward money.

    But the attitude toward money has, of course, changed. Excepting pocket money, cash of any kind is now rarely used; money as a tangible（切实，实在）commodity has largely been replaced by credit. A deficit (赤字) economy, accompanied by huge expansion, has led us to think of money as product of the creative imagination. The banker no longer offers us a safe: he offers us a service in which the most valuable element is the creativity for the invention of large numbers. It is in no way surprising, in view of this change in attitude, that we are witnessing the disappearance of the heavy-walled bank.

    Just as the older bank emphasized its strength, this bank by its architecture boasts of imaginative powers. From this point of view it is hard to say where architecture ends and human assertion (人们的说法)begins.

    Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

    This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

    “We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

    Kunta wondered why the white people had done this to him. Born a free man, he was now in chains. Heavy iron chains around his feet and hands were fixed to a metal bar that ran round the hall about ten centimeters off the ground. He was just able to lie down on the ground, but could not stand up.

    Kunta had been seized in the forest and then hit on the head with a hard object. When he woke up, his hands and feet had already been tied together. What shocked him most was that the men who carried him were black. He reasoned with them, and tried to persuade them to set him free. But they would not listen to him. When they came to the river, a white man was waiting in the boat for them. There was an argument about money, so it seemed, in a language that Kunta did not understand. Finally, Kunta was thrown into the bottom of the boat and covered with an old smelly cloth. The men took him in their boat to the castle on the coast where he was now held prisoner.

    Another thing which shocked Kunta was that women were held in the castle too. He could hear their crying, also children's voices. What was to become of them all, he wondered. For all his life, he had known that people suddenly disappeared from their villages. He had known that it was not safe to travel alone in the forest near the coast. But why did white people want to catch Africans and put them in chains? Would they be killed or even eaten? The situation seemed hopeless and he knew his life was in danger.

    Worse was to come. A few days later about 140 black people were taken and put on a tall sailing ship waiting off the coast. Once on the boat, they were taken below and their chains were fixed to two bars that ran the length of the ship. Their feet were fixed to one bar and their hands to another bar. Thus they lay on hard wooden boards, unable to stand up or move around.

    The sea journey lasted over sixty days and nights. They had rough weather and Kunta's back bled from rolling over on the hard wooden boards. Many of the men fell sick with fever. They sighed and cried out for more water, but food and water were only given out once a day. Once in a while sailors came down, Kunta thought, to carry sick men upstairs for treatment. When the ship finally arrived in a port, the wooden cover was opened wide and Kunta could see in daylight for the first time across the part of the ship where he had been chained. About a third of the people who had been chained up below at the beginning of the journey were missing.

    A chip inserted in a young quadriplegic's (四肢麻痹患者) brain is already improving his quality of life. Soon the benefits may be more widespread.

    A 25-year-old man unable to move from the neck down recently did what many assumed impossible. After a knife attack that had left him paralyzed, all he could move was his head, which he used to push a switch and call for a nurse. And he could turn his wheelchair by blowing into a straw near his face. That was it.

    Then last June, a Foxborough (Mass.) company called Cyber Kinetics opened the man's skull and inserted a special chip no larger than a baby aspirin. That insert has given him a few additional and precious abilities. When connected to a special computer via a cable, the chip translates the young man's thoughts into commands that let him move a cursor across a PC screen and open e-mail. He can draw a circle with a computer painting program. And he can use a robotic hook(钩) to perform simple tasks like picking up a candy and sliding it across a table.

    All he has to do is to think.

    Several new studies have begun or been completed in the past year. In fact, more than half of the scientific papers in this field, called brain-to-computer interaction (BCI), have been published in the past two years, notes Jonathan Wolpaw, a research physician at Wadsworth Center, the New York State Health Dept.'s research laboratory.

    Brain surgeries (手术) are no longer rare: Thousands of Parkinson's disease patients have had special devices inserted in their brains to ease uncontrollable shaking and other symptoms. The inserts themselves have improved, so the body doesn't reject them as furiously(猛烈地). And significant development has been achieved in software used to interpret the brain's signals and change them into commands understood by computers.

    But increased demand for thought technology remains the biggest reason for the field's progress. Today, 4 million Americans live with paralysis according to the Christopher Reeve Paralysis Foundation.

    Scientists hope that thought technology will reduce the impact of such disabilities. People with spinal-cord injuries, for example, often lose their ability to walk because the communications network between their brain and their legs has been interrupted. The brain still commands the leg muscles to move, but they don't hear its orders.

    Thought technology, scientists hope, will bridge this communications gap. "Our goal is for you to see paralyzed people eating at a restaurant and for you not to know that they are paralyzed," says John Donoghue, founder and chief scientific officer at Cyber Kinetics.

— Yes, that might         why he didn't do well on the test.

    Custom tattooed fish (纹身鱼) may be big sellers at markets, but an animal expert say it is a cruel and potentially lethal practice.

    In Laitai Flower and Fish Market near the Lufthansa Center in Beijing, four of over 20 fish stores sell marine ornamental fish that are tattooed using laser (激光) guns with beautiful images in order to make them more attractive to customers. Many people just love these kinds of fish, which gives them a unique visual impression. The price of these fish ranges from 50-100 yuan. Some customers are willing to pay an additional 100 yuan to have Chinese characters tattooed on to the fish. The most popular characters are “zhaocai” (attracting fortune) and “fu” (blessing). The color of tattooed fish won't fade away, and the fish can be cared for as regular fishes:

    But Ye Zhenjiang, a professor from the Ocean University of China, said “the practice would damage a fish's mackerel scale, which is its protective layer. Although I haven't done any research on the impact of the laser on mackerel scale, it is obvious that the mackerel scale may be infected or even destroyed under the exposure of laser,” Ye said. “It's like tattooing a human being's body, and it breaks the physiological balance of the fish and damages: the skin's protective surface, It may even cause death among fishes which have thin mackerel scale.”

    A specialist in aquatic(永生的) animal study surnamed Xu, from the Beijing Fisheries Research Institute, said, “We have no specific regulations to prevent fish from being tattooed. An official surnamed Bai from the Fishery Surveillance and Administration Bureau(FSAB), said there is no study showing that the laser threatened a fish's health. He said a regulation on small animal protection, to be passed in the near future, doesn't include regular aquatic animals. He said the institution is only responsible for aquatic animals that are on the verge of extinction. He said tattooed fish are mainly from south China's Guangdong province because Beijing does not have the laser technology to tattoo a fish.

    “It's too brutal to tattoo pictures or characters on fishes, even if it makes them more beautiful,” many tropical fish buyers told METRO yesterday. “We would never buy fish like that and we prefer them with natural beauty.”

    “Image is everything.” An entire industry has been built upon the concept that image is everything, but an appealing image isn't enough when there's no substance behind it.

    First of all, one should consider how important image is in selling products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. But if the product or service doesn't live up to it, customers will be very dissatisfied. The recent scandal (丑闻) about the Arthur Andersen accounting firm showed that behind that image, it had unfair business practices under the table. Despite the previous positive image, the firm is being accused of criminal actions. Although the image had been nearly perfect, the reality behind the image has led to its downfall.

    Similarly, personal consultants(顾问) can build up a very positive public image for politicians and movie stars in the view of the general commons. But once again, history is filled with examples of both that fell from grace (体面) like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind it, failure is close.

    To conclude, it's clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation(等式). What lies behind that image is every bit as important as the image itself — the person or product must live up to that image or there's little chance for long-term success.
