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 Excepting pocket money, cash of any kind is now rarely used; money as a tangible（切实，实在）commodity has largely been replaced by credit.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.

    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.

    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.

Dear Tom，

    How time flies! You (study) in Beijing for nearly a month, during which you must have achieved a lot. Well, how's everything going? It is reported that the weather there is very hot and dry these days, which is very different from of your country. Have you adapted to it? In addition, you once complained that the food (serve) there was not your taste. I hope that should have been improved.

    I am glad to tell you that I will go to Beijing to take part in an English speech contest in July, is not only an honor, but also a great opportunity for me to improve . And now I try my best to make (prepare) for it. , I have some trouble in collecting the materials relevant and using the language. I will appreciate if you give me a hand to solve the problems.

    After the contest, I am to drop at your school to visit you. Please wait for my phone.

    “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.

    Most people know precious gemstones (宝石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It's more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone's origin.

    Beneath the surface of a gemstone, on the tiny level of atoms and molecules（分子）, lie clues (线索) to its origin. At this year's meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers (激光) to clarify these clues and identify a stone's homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.

    Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.

    To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles（微粒）called electrons separate from atoms.

    The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.

    In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.

    Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.

    Time is something from which we can' t escape.  Even if we ignore it, it's still going by, ticking away, second by second, minute by minute, hour by hour. the main issue in using your time well is "Who's in charge?" We can allow time to slip by let it be our enemy. Or we can take control of it and make it ally(同盟) .

    By taking control of you spend your time, you'll increase your chances of becoming more successful student. Perhaps more importantly, the better you are at managing the time you devote your studies, the more time you'II have to spend on your outside interests .

    The aim of time management is to schedule every moment so we become slaves of a timetable governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time.

Saving money while traveling

    There are a lot of matters to think on before going out on a trip.  If you fail to plan the trip properly, then money will simply let itself loose from your pocket. Moreover, if you haven't planned a road map of your tour,  then confusion is quite inevitable (必然的).

    Package tours. Tours and travel agencies have attractive offers for tourists wanting to spend a couple of days on trips. Once you have accepted the package tour, all your expenses during the travel will be greatly reduced. You can save a lot in lodging(住宿 ) and traveling.

    Inexpensive lodging. Never choose expensive lodging if your tour is a low-budget one. People tend to spend a lot booking luxury hotels (豪华旅馆),  and save little to enjoy other activities during the trip. This idea is absolutely not wise when spending limited money on the trip is your main aim. Moreover, the expenses increase quickly when your kids are with you. You can use the money saved on good food and amusement.

    The peak season is the time when rates are sky high due to the increase of millions of tourists who can afford to spend a lot of money. You, not being amongst this crowd that can spend generously, must book your holidays during the off season.

    A guide map. Make a guide map about the places to visit, expenses of travel and the activities to try. While planning you should also estimate (估计) your total expenses. Calculate the maximum amount and try to spend less than that. Refer to the guide map while traveling and follow the money-saving travel tips as much as possible.

A. Reduce shopping.

B. Off season travel.

C. You must keep yourself updated with such offers.

D. This will help you to keep actual expenses below the estimated.

E. You can save lots of dollars when you don't have a credit card.

F. Therefore, book a fairly low-price lodge to save a few dollars.

G. So knowing some money-saving travel tips becomes necessary for you.
