听力原文: Not long ago, some of you may have read about the team of mountain climbing scientists who helped to recalculate the elevation of the highest mountain in the world, Mount Everest. Of course the elevation of Mount Everest was determined many years ago using traditional surveying methods. But these scientists wanted to make a more precise measurement, using a new method that takes advantage of recent advances in technology; it's called the Glob al Positioning System. The Global Positioning System uses 24 satellites that circle the earth. Each of the satellites is constantly sending out signals, and each signal contains important information that can be used to determine the longitude, latitude and elevation at any point on the earth’s surface. Well in order to use the system to calculate a mount of Everest's elevation, scientists need to put a special receiver on the summit to receive signals from the satellites. The problem with this was that in the past, the receivers were much too heavy for climbers to carry. But now these receivers have been reduced to about the size and weight of a hand-held telephone, so climbers were able to take the receiver to the top of the Everest, and from there, to access the satellite system signals that would allow them to determine the precise elevation. And it turns out that the famous peak is actually a few feet higher than us previously thought.

In a market system individual economic units are free to interact among each other in the market place. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, real goods such as automobiles, shoes, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not al ways be an easy task. Hence, the introduction of money as a medium of exchange eases trans actions considerably. In the modem market economy, goods and services are bought or sold for money.
An alternative to the market system is administrative control by some agency over all trans actions. This agency will issue edicts or commands as to. how much of each goods and services should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy.
In a traditional society, production and consumption patterns are governed by tradition: parentage, religion, and custom fix every person's place within the economic system. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. A stagnant society may result.
What is the main purpose of the passage?
A.To outline contrasting types of economic systems.
B.To explain the science of economics.
C.To argue for the superiority of one economics systems.
D.To compare barter and money-exchange markets.
Researchers at the Biorobotics (生物机械技术)Laboratory of McGill University in Montreal are building a robot , known as Micro Surgery robot-1(MSR- I for short), that will perform. delicate operations under the control of a human surgeon. The robot is specifically designed for performing eye surgery but could have other applications, such as the removal of brain tumors. The system could also be used to allow surgeons and their students to practise simulated surgery that feel like the real thing- without the real consequences for the patients.
During the operations, the surgeon manipulates a set of control known as the master. These are connected through a high- performance computer to the robot. Both the master and the robot have two limbs, When the surgeon moves the masters' limbs, the robots limbs move in exactly the same way, except that the movements can be scaled down as much as a thousand times. This will eliminate hand tremor and poor accuracy and thus reduce the damage to the eye that can occur with present microsurgery techniques. Each of the robots limbs has a minimum movement of one micrometer---more than one hundred times the precision of the human hand.
The computer also creates a three - dimensional robot' s eye view of the inside of the eye that the surgeon can see by wearing a virtual reality helmet (虚拟现实头盔) that has a small lens in front of each eye.
To provide the surgeon with such a realistic experience, MSR-I must be able to move rapidly, but this requires extremely fast computing. To handle the computational demands of instant interaction, the McGill team is constructing its own parallel-processing computer., It is al so studying areas such as muscle mechanism, artificial intelligence and optics, and has a already built another micro robot MR- I, capable of manipulating a single living cell.
Although commercial applications of the new system are not expected for several years, its basic mechanical components will be ready for testing in a few months, "The day when micro robots will be able to perform. surgery without human intervention is many years away," says Hunter, "in the meantime , a system such as MRS-I is a necessary precursor."
The so-called "virtual reality "mentioned in this passage is actually.
A.a surgical tool used for operations
B.a computer system used to produce life- like illusions
C.a new kind of applications in a visual technology.
D a way to carry out operations in a visual sense
By streamlining this function, however, the nature of the business changed and the importance of nurturing interbank relationships dwindled in the eyes of some correspondent bankers. Technology tends to lead to concentration, because the customer has gone to the bank that is bigger and faster, and can handle more volume, explains Ian Cormack, who heads Citicorp's financial institutions group in London and sits on the council of the clearing system in the UK.
Moving or receiving money has always been at the heart of interbank activity. Lawrence Grand, international banking director at Barclays, makes the fundamental point that correspondent banking will always exist in a world where banks have to talk to other banks to conduct money transmissions. This view is shared at Manufacturers Hanover, where Joseph Long-aberdi, a banking vice president and senior representative, believes funds transfer business is still the major product over which correspondent banks wage battle.
But while the need to balance interbank accounts remains a core function of the business, the complexion of the funds passing through the payments system has altered dramatically. The rise and rise of financial activity has displaced trade - related flows, particularly in the period after Big Bang, until today around 90 per cent of the business consists of financial transactions, estimates Mr. Cormack.
Volumes continue to rise significantly in the major clearing centres, largely feeding off growth in securities processing and foreign exchange. The value of dollar - dominated transactions passing through New York's clearing house inter - bank payments system (Chips) increased by 23.7 percent last year to a daily average of $ 526 billion, equivalent to 126 840 transactions a day, and compared with $ 425 billion and 113 758 transactions in 1986.
In London's sterling market the value of daily transactions passing through the clearing house automated payments system (Chaps) climbed by 28.5 percent in the year ending March 1988 to £45 billion, or 23 441 transactions a day, compared with £3 billion and 20 958 in the previous months.
Keeping pace with growth has not been easy, particularly for the banks which for reasons of size, cost and strategy have been confined to a marginal role in the business. Commitment to the technological infrastructure is vital. Five years ago Manufacturers Hanover had 75 million invested in a worldwide telecommunications network. Anyone who baulked at such an investment five years ago would find it difficult to enter the market today.
