Passage 1 It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits.
The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.
But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can't be answered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up, ever, and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.

Passage 2 Archaeology has long been an accepted tool for studying prehistoric cultures. Relatively recently the same techniques have been systematically applied to studies of more immediate past. This has been called “historical archaeology". A term that is used in the United States to refer to any archaeological investigation into North American sites that postdate the arrival of Europeans.
Back in the 1930s and 1940s, when restoration was popular, historical archeology was primarily a tool of architectural reconstruction. The role of archaeologists was to find the foundations of historic buildings and then take back seat to architects.
The maina for reconstruction had largely subsided by the 1950s and 1960s. Most people entering historical archaeology during this period came out of university anthropology departments where they had studied prehistoric cultures. They were, by training, social scientists, not historians, and their work tended to reflect this bias. The questions they framed and the techniques they used were designed to help them understand, as scientists, how people behaved. But because they were treading on historical ground for which there was often extensive written documentation and because their own knowledge of these periods was usually limited, their contributions to American history remained circumscribed. Their reports, highly technical and sometimes poorly written, went unread.
More recently, professional archaeologists have taken over. These researchers have sought to demonstrate that their work can be a valuable tool not only of science but also of history, providing fresh insights into the daily lives of ordinary people whose existences might not otherwise be so well documented. This newer emphasis on archaeology as social history has shown great promise, and indeed work done in this area has led to a reinterpretation of the United States past.
In Kingston, New York, for example, evidence has been uncovered that indicates that English goods were being smuggled into that city at a time when the Dutch supposedly controlled trading in the area. And in Sacramento an excavation at the site of a fashionable nineteenth-century hotel revealed that garbage had been stashed in the building's basement despite sanitation laws to the contrary.
26. What is the main topic of the passage? A. How the purpose and the methods of historical archaeology have changed. B. How archaeology has been applied to studies of prehistoric cultures. C. The attitude of professional archaeologists hold toward historical archaeology. D. The contributions make to historical archaeology.
27. According to the passage, what is a relatively new focus in archaeology? A. Studying prehistoric cultures. B. Investigating ancient sites in what is now the United States. C. Comparing the culture of North America to that of Europe. D. Studying the recent past.
28. According to the passage, when had historical archaeologists been trained as anthropologists? A. Before the 1930s B. During the 1930s and 1940s C. During the 1950s and 1960s D. After the 1960s

Passage 3 Many of the most damaging and life-threatening types of weather——torrential rains, severe thunderstorm, and tornadoes——begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $ 250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.Until recently, the observation——intensive approach needed for accurate, very short-range forecasts, or “Nowcast", was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observations over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volumeof weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

Passage 4 The relationship between the home and market economies has gone through two distinct stages. Early industrialization began the process of transferring some production processes (e.g. clothmaking, sewing and canning foods) from the home to the marketplace. Although the home economy could still produce these goods, the processes were laborious and the market economy was usually more efficient. Soon, the more important second stage was evident——the marketplace began producing goods and services that had never been produced by the home economy, and the home economy was unable to produce them (eg. electricity and electrical appliances, the automobile, advanced education, sophisticated medical care). In the second stage, the question of whether the home economy was less efficient in producing these new goods and services was irrelevant; if the family were to enjoy these fruits of industrialization, they would have to be obtained in the marketplace. The traditional ways of taking care of these needs in the home, such as in nursing the sick, became socially unacceptable (and, in most serious cases, probably less successful). Just as the appearance of the automobile made the use of the horse-drawn carriage illegal and then impractical, and the appearance of television changed the radio from a source of entertainment to a source of background music, so most of the fruits of economic growth did not increase the options available to the home economy to either produce the goods or services or purchase them in the market. Growth brought with it increased variety in consumer goods, but not increased flexibility for the home economy in obtaining these goods and services. Instead, economic growth brought with it increased consumer reliance on the marketplace. In order to consume these new goods and services, the family had to enter the marketplace as wage earners and consumers. The neoclassical model that views the family as deciding whether to produce goods and services directly or to purchase them in the marketplace is basically a model of the first stage. It cannot accurately be applied to the second (and current) stage.
36. The reason why many production processes were taken over by the marketplace was that . A. it was a necessary step in the process ofindustrialization B. they depended on electricity available only to the market economy C. it was troublesome to produce such goods in the home D. the marketplace was more efficient with respect to these processes
37. It can be seen from the passage that in the second stage . A. some traditional goods and services were not successful when provided by the home economy B. the market economy provided new goods and services never produced by the home economy C. producing traditional goods at home became socially unacceptable D. whether new goods and services were produced by the home economy became irrelevant
38. During the second stage, if the family wanted to consume new goods and services, they had to enter the marketplace . A. as wage earners B. both as manufacturers and consumers C. both as workers and purchasers D. as customers
39. Economic growth did not make it more flexible for the home economy to obtain the new goods and service because . A. the family was not efficient in production B. it was illegal for the home economy to produce them C. it could not supply them by itself D. the market for these goods and services was limited
40. The neoclassical model is basically a model of the first stage, because at this stage . A. the family could rely either on the home economy or on the marketplace for the needed goods and services B. many production processes were being transferred to the marketplace C. consumers relied more and more on the market economy D. the family could decide how to transfer production processes to the marketplace
