单选题Guthrie's contiguity principle offers practical suggestions for how to break habits. One application of the threshold method involves the time young children spend on academic activities. Young children have short attention spans, so the length of time they can sustain work on one activity is limited. Most activities are scheduled to last no longer than 30 to 40 minutes. However, at the start of the school year, attention spans quickly wane and behavior problems often result. To apply Guthrie's theory, a teacher might, at the start of the year, limit activities to 15 to 20 minutes. Over the next few weeks the teacher could gradually increase the time students spend working on a single activity. The threshold method also can be applied to teaching printing and handwriting. When children first learn to form letters, their movements are awkward and they lack fine motor coordination. The distances between lines on a page are purposely wide so children can fit the letters into the space. If paper with narrow lines is initially introduced, students' letters would spill over the borders and students might become frustrated. Once students can form letters within the larger borders, they can use paper with smaller borders to help them refine their skills. The fatigue method can be applied when disciplining disruptive students who build paper airplanes and sail them across the room. The teacher can remove the students from the classroom, give them a large stack of paper, and tell him to start making paper airplanes. After the students have made Several airplanes, the activity should lose its attraction and paper will become a cue for not building airplanes. Some students continually race around the gym when they first enter their physical education class. To employ the fatigue method, the teacher might decide to have these students continue to nm a few more laps after the class has begun. The incompatible response method can be used with students who talk and misbehave in the media center. Reading is incompatible with talking. The media center teacher might ask the students to find interesting books and read them while in the center. Assuming that the students find the books enjoyable, the media center will, over time, become a cue for selecting and reading books rather than for talking with other students. In a social studies class some students regularly fall asleep. The teacher realized that using the board and overhead projector while lecturing was very boring. Soon the teacher began to incorporate other elements into each lesson, such as experiments, and debates, in an attempt to involve students and raise their interest in the course.

单选题{{B}}Passage Three{{/B}} Industrial production managers coordinate the resources and activities required to produce millions of goods every year in the United States. Although their duties vary from plant to plant, industrial production managers share many of the same major responsibilities. These responsibilities include production scheduling, staffing, procurement and maintenance of equipment, quality control, inventory control, and the coordination of production activities with those of other departments. The primary mission of industrial production managers is planning the production schedule within budgetary limitations and time constraints. They do this by analyzing the plant's personnel and capital resources to select the best way of meeting the production quota. Industrial production managers determine, often using mathematical formulas, which machines, will be used, whether new machines need to be purchased, whether overtime or extra shifts are necessary, and what the sequence of production will be. They monitor the production run to make sure that it stays on schedule and correct any problems that may arise. Industrial production' managers also must monitor product standards. When quality drops below the established standard, they must determine why standards are not being maintained and how to improve the product. If the problem relates to the quality of work performed in the plant, the manager may implement better training programs, reorganize the manufacturing process, or institute employee suggestion or involvement programs. If the cause is substandard materials, the manager works with the purchasing department to improve the quality of the product's components. Because the work of many departments is interrelated, managers work closely with heads of other departments such as sales, procurement, and logistics to plan and implement company goals, policies, and procedures. For example, the production manager works with the procurement department to ensure that plant inventories are maintained at their optimal level. This is vital to a firm's operation because maintaining the inventory of materials necessary for production ties up the firm's financial resources, yet insufficient quantities cause delays in production. A breakdown in communications between the production manager and the purchasing department can cause slowdowns and a failure to meet production schedules. Just-in- time production techniques have reduced inventory levels, making constant communication among the manager, suppliers, and purchasing departments even more important. Computers play an integral part in this coordination. They also are used to provide up-to-date information on inventory, the status of work in progress, and quality standards. Production managers usually report to the plant manager or the vice president for manufacturing, and may act as liaison between executives and first-line supervisors. In many plants, one production manager is responsible for all aspects of production. In large plants with several operations, there are managers in charge of each operation, such as machining, assembly or finishing.

单选题Passage 1 In the late 20th century, information has acquired two major utilitarian connotations. On the one hand, it is considered an economic resource, somewhat on par with other resources such as labor, material, and capital. This view stems from evidence that the possession, manipulation, and use of information can increase the cost-effectiveness of many physical and cognitive processes. The rise in information-processing activities in industrial manufacturing as well as in human problem solving has been remarkable. Analysis of one of the three traditional divisions of the economy, the service sector, shows a sharp increase in information-intensive activities since the beginning of the 20th century. By 1975 these activities accounted for half of the labor force of the United States, giving rise to the so-called information society. As an individual and societal resource, information has some interesting characteristics that separate it from the traditional notions of economic resources. Unlike other resources, information is expansive, with limits apparently imposed only by time and human cognitive capabilities. Its expansiveness is attributable to the following (1) it is naturally diffusive; (2) it reproduces rather than being consumed through use; and (3) it can be shared only, not exchanged in transactions. At the same time, information is compressible, both syntactically and semantically. The second perception of information is that it is an economic commodity, which helps to stimulate the worldwide growth of a new segment of national economies -- the information service sector. Taking advantage of the properties of information and building on the perception of its individual and societal utility and value, this sector provides a broad range of information products and services. By 1992 the market share of the U.S. information service sector had grown to about $25 billion. This was equivalent to about one-seventh of the country's computer market, which in turn represented roughly 40 percent of the global market in computers in that year. However, the probable convergence of computers and television (which constitutes a market share 100 times larger than computers) and its impact on information services, entertainment, and education are likely to restructure the respective market shares of the information industry before the onset of the 21 st century.

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:
