Reading Comprehension ( 40 points )Directions: There are five passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked with A, B, C and D. You should decide on the BEST choices and then mark the corresponding letter on the ANSWER SHEET.Passage OneI recently revisited the city which I was born in, which is a place well known for a castle built on a rock overlooking the surrounding plains, and even better known for a legendary figure who robbed the rich to give to the poor. As I toured the castle and its museum, visited the town center, and roamed around old haunts, I reflected on how the buildings that people of different eras build reflect their central preoccupations.The castle was originally built in the eleventh century, and remained important for several centuries. Throughout the medieval period castles and fortified houses were built. The powerful landowners surveyed and dominated the surrounding lands, the source of their wealth and prestige.Once the industrial era began, castles were sidelined. The merchants and factory owners built town halls, churches, factories and imposing office buildings. The town center reflects this era. An imposing town hall, complete with massive pillars and monumental lions, overlooks the town square. The square is surrounded by equally massive blocks of shops, banks and offices, built to reflect the power of trade in the heyday of the British Empire.Most people, who enter the city today never visit the castle or the old market square, head for the two shopping malls situated at either end of the city center. Here the visitor can shop to their hearts content in an environment of glass and polished chrome. Modern man is no longer a warrior defending his land, or a builder of churches, or a governor of people: he is primarily a consumer. The buildings our generation leaves to posterity will reflect our predominant interest--- shopping.16.The author's approach to the topic can best be described asA.How people change their mind when paying a visitB.Tourists today are less historical-mindedC.A comparative look between the old and the modernD.Shopping is more significant than castle visits17.According to the author, the central preoccupation of different eras could be reflected through _____.A.their landsB. their interestsC. the plains that could be overlookedD. the way they make their buildings18.Castles prove to be useful, in this passage, _____.A.before the industrial revolutionB. when tourists want to shop in themC. as merchants and governors like them to beD. because they are imposing19.Which of the following is the symbol of the British Empire, according to the passage?A.The castles and fortified houses.B. Massive blocks of shops, banks and offices.C. Building with glass and polished chrome.D. Town halls, churches, factories and imposing office buildingsPassage TwoThe study of ecology has taught us that diversity is important to stabilityin the natural world. Modern agricultural practices and other human interventionsin the environment reduces the number of interacting species making the ecosystem vulnerable and unstable.Similarly, human society in its progress toward the cliched global village is liable to make the world less stable not more stable. We are eliminating languages, traditional diets, and eroding cultural practices at an alarming rate. The whole world wants to speak the same language, eat the same food and wear the same clothes. But will this homogeneity be good for the human species? Biologists would tend to say no.Certainly a world where we can all understand each other and share common interests is appealing on one level. But how infinitely poorer we will all be if we travel 5000 miles from home only to find no new people, no new places, no new ways of living, just a copy of what you experience back home.20.According to the author, to speak the same language, eat the same food and wear the same clothes are _____.A.the wishes of people around the worldB.study of biology is of primary importantC.of more demerits than meritsD. keeping the world stable21. The author implies that ______.A.human intervention into the natural environment may reduce the number of speciesB.human intervention into the natural environment may cause the invulnerabilityof ecosystemC. agricultural practices influence interaction between speciesD. agricultural practice is one of the causes for the stability of ecosystem.22. It is true, according to the passage, that ____.A.if we travel 5,000 miles, we will become poorerB.traveling to new places and meeting new people will make us poorer than everC.if we cannot see the differences when traveling afar, what’s the use of traveling?D. if we cannot see the differences when traveling afar, we can infinitely eat the same food and wear the same clothes23. The word “homogeneity” may probably mean______.A.homo sapiensB. homosexualityC. samenessD. homelinessPassage ThreeSmith’s 1776 work, "An Inquiry Into the Nature and Causes of the Wealth of Nations," also shortened as "The Wealth of Nations," appeared at the dawn of industrial development in Europe. While critics note that Smith didn't invent many of the ideas that he wrote about, he was the first person to compile and publish them in a format designed to explain them to the average reader of the day. As a result, he is responsible for popularizing many of the ideas that underpin the school of thought that became known as classical economics.Other economists built on Smith's work to solidify classical economic theory,which would become the dominant school of economic thought through the Great Depression. In this book, Smith discussed the stages of evolution of society, from a hunter stage without property rights or fixed residences to nomadic agriculture with shifting residences. A feudal society is the next stage. In this stage, laws, and property rights are established to protect privileged classes. Laissez-faire （自由放任）or free markets characterize modern society in which new institutions are established to conduct market transactions.Laissez-faire philosophies, such as minimizing the role of government intervention and taxation in the free markets, and the idea that an "invisible hand" guides supply and demand are among the key ideas Smith's writing is responsible for promoting. These ideas reflect the concept that each person, by looking out for him or herself, inadvertently helps to create the best outcome for all. "It is not from the benevolence of the butcher, the brewer, or the baker, that we can expect our dinner, but from their regard to their own interest," Smith wrote.24.In the 1st paragraph, the author says that ____.A.ideas in “the Wealth of Nations”had never been known to ordinary readers before Smith proposed themB.it was not until the publication of Smith’s book did some of the ideas become popularC.these ideas had long been known to people in Europe but Smith framed them into his writingD.Smith didn’t invent any of these ideas that he wrote about,but he was the first to know about them.25.In the 2nd paragraph, Smith divided stages of social evolution into _____.A.three stages, i.e., hunter stage, stage of nomadic agriculture and stage of feudal society and each is distinguished with property rightB.two stages, i.e., stage of hunter and nomadic agriculture, and stage of feudal society and each is distinguished with fixed residenceC.four stages, i.e., hunter stage, stage of nomadic agriculture, stage of feudalsociety and stage of privileged classes, each distinguished with shifting residence D. three stages, i.e., hunter stage, stage of nomadic agriculture and stage of feudal society, each distinguished with fixed residence, shifting residence and property right26. Which of the following is not the key idea of Adam Smith?A.There is an invisible hand guiding supply and demand in the free market.ernment should give the least intervention into the market.C.Each person should work inadvertently on their own.D.A baker’s interest may bring us the meal that we expect.27.“Invisible hand” in this context refers to _____.A.demand and supply in a free market could be regulated on its ownernment’s role could be self-reduced through minimizationC.benevolence of the butcher, the brewer, or the baker cannot be seenD.ideas proposed by Smith are invisible but have to be written and publishedPassage FourArtificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning (the acquisition of information and rules for using the information), reasoning (using rules to reach approximate or definite conclusions) and self-correction. Particular applications of AI include expert systems, speech recognition and machine vision.AI can be categorized as either weak or strong. Weak AI, also known as narrow AI, is an AI system that is designed and trained for a particular task. Virtual personal assistants, such as Apple's Siri, are a form of weak AI. Strong AI, also known as artificial general intelligence, is an AI system with generalized human cognitive abilities. When presented with an unfamiliar task, a strong AI system is able to find a solution without human intervention.Because hardware, software and staffing costs for AI can be expensive, many vendors are including AI components in their standard offerings, as well as access to Artificial Intelligence as a Service (AIaaS) platforms. AI as a Service allows individuals and companies to experiment with AI for various business purposes and sample multiple platforms before making a commitment. Popular AI cloud offerings include Amazon AI services, IBM Watson Assistant, Microsoft Cognitive Services and Google AI services.Some industry experts believe that the term artificial intelligence is too closely linked to popular culture, causing the general public to have unrealistic fears about artificial intelligence and improbable expectations about how it will change the workplace and life in general. Researchers and marketers hope the label augmented intelligence, which has a more neutral connotation, will help people understand that AI will simply improve products and services, not replace the humans that use them.28.The machine that owns the processes to ______could be called AI.A.learn, correct itself and recognize speechB. to see, learn by itself and recognizeC. to correct itself and learn by itself and judge on its ownD. to recognize human speech, play the role of expert and hear what human says29. The main difference between strong and weak AI is that_____.A. strong AI is based on more general cognitive ability than a weak oneB. a weak AI can fulfill a particular mission more efficiently than a strong oneC. given an unfamiliar task, a weak AI would recognize it immediatelyD. could be found in Apple’s Siri, Google, Amazon and IBM, etc.30. Access to Artificial Intelligence as a Service platforms is allowed because_____.A. experiment with AI for various business purposes could be very expensiveB. sampling multiple platforms before making a commitment is importantC. cost to AI as a service is so high that no individual or company could afford itD. costs to make AI is so high that no individual or company could afford it31. The main human concern over AI in this passage mainly refers to ______.A. whether AI will help them with difficult jobsB. that AI will finally take their placeC. whether AI will use themD. if AI will improve products and servicesPassage FiveScientific investigation is a studious research or inquiry; especially examination or experimentation aimed at the discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws. While the techniques that scientists use to conduct research may differ across disciplines, like mathematics, physics, biology, chemistry, literature, history, philosophy, or any other scientific field, the underlying principles and objectives are similar. The scientific method, for instance, is defined in The Oxford English Dictionary as “a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypothesis.”The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind. It is simply the mode at which all phenomena are reasoned about, rendered precise and exact. There is no more difference, but there is just the same kind of difference, between the mental operations of a man of science and those of an ordinary person, as there is between the operations and methods of a baker or a butcher weighing out his goods in common scales, and the operations of a chemist in performing a difficult and complex analysis by means of his balance and finely graduated weights. It is not that the action of scales in the one case, and the balance in the other, differ in the principles of their construction or manner of working; but the beam of one is set on a indefinitely finer axis than the other, and of course turns by the addition of a much smaller weight.32.Methods of scientific investigation, regardless of natural science and social science or humanities studies, are____.A.different in essenceB. of great difference in scaleC. similar in phenomenaD. basically similar33. According to the passage, the difference between a chemist and a butcher weighing something is that ____.A. the former operates more mentally than the latterB. the former does it more indefinitelyC. the latter does it with less principle than the formerD. the latter balances less than the former34. Which of the following may serve as the best topic for this passage?A. Scientific researches and experimentation.B. What is meant by method of scientific investigation?C. How to demonstrate a hypothesis?D. Differences of scientific investigation across disciplines.35. Which of the following is true, according to the passage?A. The Oxford English Dictionary does not mentioned social science when giving definition of scientific method.B. The scale used by a baker is not the same as that of a scientist.C.The Oxford English Dictionary’s definition of scientific method includes systematic observation, measurement, and experiment, and the formulation, testing, but not modification of hypothesis.D. The method of scientific investigation is nothing of the expression of the necessary mode of working of the human mind.Section III Translation (25 points)Part One English-Chinese Translation (15 points)Directions: Read the following paragraph carefully and then translate it into Chinese. Your translation should be written clearly on ANSWER SHEET.36.In science, validity is the extent to which a concept, conclusion, or measurement is well founded and corresponds accurately to the real world. It has also been defined as an overall assessment of the degree to which evidence and theory support the interpretation of the scores entailed by proposed uses of the instrument. To phrase it simply, validity refers to the degree to which evidence and theory support the interpretations of measures. These definitions prompt questions about the “real” meaning and interpretation of scores collected with health measurement instruments. The word “valid” is derived from the Latin “validus,” meaning strong. In that sense, the validity of a measurement instrument is the degree to which it measures what it claims to measure.Part Two Chinese - English Translation (10 points)Directions: Read the following paragraph carefully and then translate it into English. Your translation should be written clearly on ANSWER SHEET.37.用另一种语言工作可能会又尴尬又有挑战性，但是它也会有非常多的积极面。
