单选题Fill in each numbered blank in the following passage with ONE suitable word to complete the passage. It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions, the bases{{U}} (56) {{/U}}the decisions we make, and the roots of our habits and skills are to be{{U}} (57) {{/U}}in our past experiences ,which are brought into the present{{U}} (58) {{/U}}memory. Memory can be defined as the capacity to keep{{U}} (59) {{/U}}available for later use. It includes not only "remembering" thing like arithmetic or historical facts, but also any change in the way an animal typically behaves. Memory is{{U}} (60) {{/U}}when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat. Memory{{U}} (61) {{/U}}not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer{{U}} (62) {{/U}}that of a human being. The instant-access memory of a large computer may hold up to 100, 000" words" ready for{{U}} (63) {{/U}}use. An average American teenager probably recognizes the meanings of about 100, 000 words of English. However, this is but a fraction of the total{{U}} (64) {{/U}}of information which the teenager has stored. Consider, for example, the number of facts and places that the teenager can recognize on sight. The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person's memory is in terms of words and{{U}} (65) {{/U}}of words.

单选题{{B}}Passage 4{{/B}} Engineering students are supposed to be examples of practicality and rationality, but when it comes to my college education, I am an idealist and a fool. In high school I wanted to be an electrical engineer and, of course, any sensible student with my aims would have chosen a college with a large engineering department, famous reputation and lot of good labs and research equipment. But that's not what I did. I chose to study engineering at a small liberal-arts university that doesn't even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren't studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them. I headed off to college, feeling sure I was going to have an advantage over those students who went to big engineering "factories" where they didn't care if you had values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanist all in one. Now I'm not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses with liberal arts courses, I have learned there are reasons why few engineering students try to reconcile engineering with liberal arts courses in college. The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don't mix as easily as I assumed in high school. Individually they shape a person in very different ways; together {{U}}they{{/U}} threaten to confuse. The struggle to reconcile the two fields of study is difficult.

单选题Science is an enterprise concerned with gaining information about causality, or the relationship between cause and effect. A simple example of a cause is the movement of a paddle as it strikes a ping-pong ball; the effect is the movement of the ball through the air. In psychology and other sciences, the word "cause" is often replaced by the term "independent variable". This term implies that the experimenter is often "free" to vary the independent variable as he or she desires (for example, the experimenter can control the speed of the paddle as it strikes the ball). The term "dependent variable" replaces the word "effect", and this term is used because the effect depends on some characteristic of the independent variable (the flight of the ball depends on the speed of the paddle). The conventions of science demand that both the independent and dependent variables be observable events, as is the case in the ping-pong example. In the case of biorhythm theory, the independent variable is the number of days that have elapsed between a person's date of birth and some test day. The dependent variable is the person's level of performance on some specified task on the test day. Notice that although the experimenter is not free to choose a birthday for a given individual, persons with different dates of birth can be tested on the same day, or a single subject can be tested on several different days. In order to predict the relationship between independent and dependent variables, many scientific theories make use of what are called intervening variables. Intervening variables are purely theoretical concepts that cannot be observed directly. To predict the flight of a ping-pong ball, Newtonian physics relies on a number of intervening variables; including force, mass, air resistance, and gravity. You can probably anticipate that the intervening variables of biorhythm theory are the three bodily cycles with their specified time periods. It should be emphasized that not all psychological theories include intervening variables, and some psychologists object to their use precisely because they are not directly observable. The final major component of a scientific theory is its syntax, or the rules and definitions that state how the independent and dependent variables are to be measured, and that specify the relationships among independent variables, intervening variables, and dependent variables. It is the syntax of biorhythm theory that describes how to use a person's birthday to calculate the current status of the three cycles. The syntax also relates the cycles to the dependent variable, performance, by stating that positive cycles should cause high levels of performance whereas low or critical cycles should cause low performance levels. To summarize, the components of a scientific theory can be divided into four major categories: independent variables, dependent variables, intervening variables, and syntax.

单选题 Passage 2 If income is transferred from rich persons to poor persons the proportion in which different sorts of goods and services are provided will be changed. Expensive luxuries will give place to more necessary articles, rare wines to meat and bread, new machines and factories to clothes and improved small dwellings; and there will be other changes of a like sort. In view of this fact, it is inexact to speak of a change in the distribution of the dividend in favor of or adverse to, the poor. There is not a single definitely constituted heap of things coming into being each year and distributed now in one way, now in another. In fact, there is no such thing as the dividend from the point of view of both of two years, and therefore, there can be no such thing as a change in its distribution. This, however, is a point of words rather than of substance. What I mean when I say that the distribution of the dividend has changed in favor of the poor is that, the general productive power of the community being given, poor people are getting more of the things they want at the expense of rich people getting less of the things they want. It might be thought at first sight that the only way in which this could happen would be through a transference of purchasing power from the rich to the poor. That, however, is not so. It is possible for the poor to be advantaged and the rich damaged, even though the quantity of purchasing power, i. e. of command over productive resources, held by both groups remains unaltered. This might happen if the technical methods of producing something predominatingly consumed by the poor were improved and at the same time those of producing something predominatingly consumed by the rich were worsened, and if the net result was to leave the size of the national dividend as defined in Chapter V. unchanged. It might also happen if, by a system of rationing or some other device, the rich were forced to transfer their demand away from things which are important to the poor and which are produced under such conditions that diminished demand leads to lowered prices. Per contra - and this point will be seen in Part Ⅳ. To be very important practically - the share, both proportionate and absolute of command over the country's productive resources held by the poor may be increased, and yet, if the process by which they acquire this greater share involves an increase in the cost of things that play a large part in their own consumption, they may not really gain. Thus a change in distribution favorable to the poor may be brought about otherwise than by a transference of purchasing power, or command over productive resources, to them, and it does not mean a transference of these things to them. None the less, this sort of transference is the most important, and may be regarded as the typical, means by which changes in distribution favorable to the poor come about.Comprehension Questions:

单选题There are people in Italy who can"t stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn or even frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it"s a game better suited to the 19 th century, slow, quiet, gentlemanly. These are the same people you may be one of them who love football because there"s the sport that glorifies "the hit". By contrast, baseball seems abstract, cool, silent, still. On TV the game is fractured into a dozen perspectives, replays, close-ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time for involvement. The TV won"t do it for you. Take, for example, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or brings the glove to a point in front of him, takes a step fight or left, backward or forward, perhaps he glances across the field to check his first baseman"s position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed." The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in frontof you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood. If football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.

单选题In old days, when a glimpse of stocking was looked upon as something far too shocking to distract the serious work of an office, secretaries were men. Then came the First World War and the male secretaries were replaced by women. A man's secretary became his personal servant, charged with remembering his wife's birthday and buying her presents; taking his suits to the dry cleaners; telling lies on the telephone to keep people he did not wish to speak to at by; and, of course, typing and filing and taking shorthand. Now all this may be changing again. The microchip and high technology is sweeping the British office, taking with it much of the routine clerical work that secretaries did. "Once office technology takes over generally, the status of the job will rise again because it will involve only the high-powered work--and then men will want to do it again. " That was said by one of the executives (male) of one of the biggest secretarial agencies in this country. What he has predicted is already under way in the US. One girl described to me a recent temporary job placing men in secretarial jobs in San Francisco. She noted that all the men she dealt with appeared to be gay so possibly that is just new twist to the old story. Over here, though, there are men coming onto the job market as secretaries. Classically, girls have learned shorthand and typing and gone into a company to seek their fortune from the bottom--and that's what happened to John Bowman. Although he joined a national grocery chain as secretary to its first woman senior manager, he has since been promoted to an administration job. "I filled in the application form and said I could do audio/typing, and in fact I was the only applicant. The girls were reluctant to work for this young, glamorous new woman with all this power in the firm." "I did typing at school, and then a commercial course. I just thought it would be useful finding a job. I never got any funny treatment from the girls, though I admit I've never met another male secretary. But then I joined the Post Office as a clerk and carelessly played with the typewriter, and wrote letters, and thought that after all secretaries were getting a good£1, 000 a year more than clerks like me. There was a shortage at that time, you see." "It was simpler working for a woman than for a man. I found she made decisions, she told everybody what she thought, and there was none of that male bitchiness, or that stuff 'ring this number for me dear, ' which men go in for." "Don't forget, we were a team-that's how I feel about in--not boss and servant but two people doing different things for the same purpose." Once high technology has made the job of secretary less routine, will there be made takeover? Men should beware of thinking that they can walk right into the better jobs. There are a lot of women secretaries who will do the job as well as they because they are as efficient and well trained to cope with word processors and computers, as men.

单选题The growth of cell-phone users in the U.S. has tapered off from the breakneck pace of 50% annually in the late 1990s to what analysis project will be a 15% to 20% rise in 2002, and no more than that in 2003. To some extent, numerous surveys have found, slower growth in demand reflects consumer disillusionment with just about every aspect of cell-phone service--its reliability, quality, and notorious customer service. The cooling off in demand threatens to cascade through the industry: The big four U.S. cell-phone carders--Verizon Wireless, Cingular Wireless, AT&T Wireless, Sprint imperil their timetables for becoming profitable, not to mention their efforts to whittle down their mountains of debt. As the carders have begun to cut costs, wireless- equipment makers--companies such as Lucent, Nokia, and Ericsson--have been left with a market that's bound to be smaller than they had anticipated. Handset makers have been insulated so far, but they, too, face a nagging uncertainty. They'll soon introduce advanced phones to the U.S. market that will run on the new networks the carders are starting up over the next year or two. But the question then will be : Will Americans embrace these snazzy data features--and their higher costs--with the wild enthusiasm that Europeans and Asians have? Long before the outcome in clear, the industry will have to adopt a new mind-set. "In the old days, it was all about connectivity. " says Andrew Cole, an analyst with wireless consultancy Adventis. Build the network, and customers will come. From now on, the stakes will be higher. The new mantra: Please customers, or you may not survive. To work their way out of this box, the carders are spending huge sums to address the problem. Much of Sprint PCS's $3.4 billion in capital outlays this year will be for new stations. And in fact, the new high-speed, high-capacity nationwide networks due to roll out later this year should help ease the calling-capacity crunch that has caused many consumer complaints. In the meantime, some companies are using better training and organization to keep customers happy. The nation's largest rural operator, Alltel (AT), recently reorganized its call centers so that a customer's query goes to the first operator who's available anywhere in the country, instead of the first one available in the customer's home area. That should cut waiting time to one minute from three to five minutes previously.

单选题In modern days, on the western bank of the upper Tigris River stands an Iraqi city called Qal'at Shartlat. Thousands of years ago, this very site was once the capital of a great Mesopotamian empire. At the lime, the place had a different name. It was called Ashur or Arrur. The word Ashur eventually gave rise to the team Assyria, which was the northern part of Mesopotamia. People living in that region later became known as the Assyrians. Historians often divide the long history of Assyria into three periods even though they cannot reach a consensus over the exact dates of each era. The three periods was the Old Assyrian Period(circa 2000 B. C. —1400 B. C.), the Middle Assyrian Period(circa 1365 B. C. —1100 B. C.)and the Neo-Assyrian Empire(circa 934 B. C. —609 B. C.). Archaeological evidence showed mat people began to settle in Ashur as early as 2500 B. C. But it did not attain any political significance until the third dynasty of Ur collapsed in 2004 B. C. After that fiasco, the Assyrians transformed the Ashur into a bustling commercial center, controlling trade routes to and from Anatolia. In 1813 B. C. , the first great Assyrian king, Shamshi-Adad I, ascended the throne and began a series of military expansions. At the height of his reign, his kingdom owned the entire northern Mesopotamia. Its growing influence gave its neighbor plenty of reasons to be wary. While things were going splendidly for this Assyrian upstart, Shamshi-Adad passed away in 1791 B. C. Soon after his death, the kingdom began to fall apart. Knowing that the Shamshi-Adad's empire was on the verge of collapse, Hammurabi of the 1* dynasty of Babylon jumped at the chance and invaded northern Mesopotamia. He conquered Ashur in 1760 B. C. From that point on to the middle of 1300s B. C. , Assyria was reduced to a mere vassal state. At first, it had to answer to the 1st dynasty of Babylon. After that empire was eradicated, it turned to submit to a Hurrian kingdom called Mitanni. It was not until 1365 B. C. that Assayria, then ruled by Ashur-uballit I, was able to regain its independence. For the next couple hundred years, Assyria grew increasingly powerful. It eventually defeated Babylonia and even occupied Egypt.
