Between the eighth and eleventh centuries A. D., the Byzantine Empire staged an almost unparalleled economic and cultural revival, a recovery that is all the more striking because it followed a long period of severe internal decline. By the early eighth century, the empire had lost roughly two-thirds of the territory it had possessed in the year 600, and its remaining area was being raided by Arabs and Bulgarians, who at times threatened to take Constantinople and extinguish the empire altogether. The wealth of the state and its subjects was greatly diminished, and artistic and literary production had virtually ceased. By the early eleventh century, however, the empire had regained almost half of its lost possessions, its new frontiers were secure, and its influence extended far beyond its borders. The economy had recovered, the treasury was full, and art and scholarship had advanced.
To consider the Byzantine military, cultural, and economic advances as differentiated aspects of a single phenomenon is reasonable. After all, these three forms of progress have gone together in a number of states and civilizations. Rome under Augustus and fifth-century Athens provide the most obvious examples in antiquity. Moreover, an examination of the apparent sequential connections among military, economic, and cultural forms of progress might help explain the dynamics of historical change.
The common explanation of these apparent connections in the case of Byzantium would run like this: when the empire had turned back enemy raids on its own territory and had begun to raid and conquer enemy territory, Byzantine resources naturally expanded and more money became available to patronize art and literature. Therefore, Byzantine military achievements led to economic advances, which in turn led to cultural revival.
No doubt this hypothetical pattern did apply at times during the course of the recovery. Yet it is not clear that military advances invariably came first, economic advances second, and intellectual advances third. In the 860’s the Byzantine Empire began to recover from Arab incursions so that by 872 the military balance with the Abbasid Caliphate had been permanently altered in the empire’s favor. The beginning of the empire’s economic revival, however, can be placed between 810 and 830. Finally, the Byzantine revival of learning appears to have begun even earlier. A number of notable scholars and writers appeared by 788 and, by the last decade of the eighth century, a cultural revival was in full bloom (in full bloom: adv.开着花), a revival that lasted until the fall of Constantinople in 1453. Thus the commonly expected order of military revival followed by economic and then by cultural recovery was reversed in Byzantium. In fact, the revival of Byzantine learning may itself have influenced the subsequent economic and military expansion.
1.     Which of the following best states the central idea of the passage?
(A) The Byzantine Empire was a unique case in which the usual order of military and economic revival preceding cultural revival was reversed.
(B) The economic, cultural, and military revival in the Byzantine Empire between the eighth and eleventh centuries was similar in its order to the sequence of revivals in Augustan Rome and fifth century Athens.
(C) After 810 Byzantine economic recovery spurred a military and, later, cultural expansion that lasted until 1453.
(D) The eighth-century revival of Byzantine learning is an inexplicable phenomenon, and its economic and military precursors have yet to be discovered.E
(E) The revival of the Byzantine Empire between the eighth and eleventh centuries shows cultural rebirth preceding economic and military revival, the reverse of the commonly accepted order of progress.
2.     The primary purpose of the second paragraph is which of the following?
(A) To establish the uniqueness of the Byzantine revival
(B) To show that Augustan Rome and fifth-century Athens are examples of cultural, economic, and military expansion against which all subsequent cases must be measured
(C) To suggest that cultural, economic, and military advances have tended to be closely interrelated in different societies
(D) To argue that, while the revivals of Augustan Rome and fifth-century Athens were similar, they are unrelated to other historical examplesC
(E) To indicate that, wherever possible, historians should seek to make comparisons with the earliest chronological examples of revival
3.     It can be inferred from the passage that by the eleventh century the Byzantine military forces
(A) had reached their peak and begun to decline
(B) had eliminated the Bulgarian army
(C) were comparable in size to the army of Rome under Augustus
(D) were strong enough to withstand the Abbasid Caliphate’s military forcesD
(E) had achieved control of Byzantine governmental structures
4.     It can be inferred from the passage that the Byzantine Empire sustained significant territorial losses
(A) in 600
(B) during the seventh century
(C) a century after the cultural achievements of the Byzantine Empire had been lost
(D) soon after the revival of Byzantine learningB
(E) in the century after 873
5.     In the third paragraph, the author most probably provides an explanation of the apparent connections among economic, military, and cultural development in order to
(A) suggest that the process of revival in Byzantium accords with this model
(B) set up an order of events that is then shown to be not generally applicable to the case of Byzantium
(C) cast aspersions on traditional historical scholarship about Byzantium
(D) suggest that Byzantium represents a case for which no historical precedent existsB
(E) argue that military conquest is the paramount element in the growth of empires
6.     Which of the following does the author mention as crucial evidence concerning the manner in which the Byzantine revival began?
(A) The Byzantine military revival of the 860’s led to economic and cultural advances.
(B) The Byzantine cultural revival lasted until 1453.
(C) The Byzantine economic recovery began in the 900’s.
(D) The revival of Byzantine learning began toward the end of the eighth century.D
(E) By the early eleventh century the Byzantine Empire had regained much of its lost territory.
7.     According to the author, “The common explanation” (line 28) of connections between economic, military, and cultural development is
(A) revolutionary and too new to have been applied to the history of the Byzantine Empire
(B) reasonable, but an antiquated theory of the nature of progress
(C) not applicable to the Byzantine revival as a whole, but does perhaps accurately describe limited periods during the revival
(D) equally applicable to the Byzantine case as a whole and to the history of military, economic, and cultural advances in ancient Greece and RomeC
(E) essentially not helpful, because military, economic, and cultural advances are part of a single phenomenon

In the eighteenth century, Japan’s feudal overlords, from the shogun (shogun: n.<>幕府时代的将军) to the humblest samurai (samurai: n.(封建时代的)日本武士,日本陆军军官), found themselves under financial stress. In part, this stress can be attributed to the overlords’ failure to adjust to a rapidly expanding economy, but the stress was also due to factors beyond the overlords’ control. Concentration of the samurai in castle-towns had acted as a stimulus to trade. Commercial efficiency, in turn, had put temptations in the way of buyers. Since most samurai had been reduced to idleness by years of peace, encouraged to engage in scholarship and martial exercises or to perform administrative tasks that took little time, it is not surprising that their tastes and habits grew expensive. Overlords’ income, despite the increase in rice production among their tenant farmers, failed to keep pace with their expenses. Although shortfalls in overlords’ income resulted almost as much from laxity among their tax collectors (the nearly inevitable outcome of hereditary office-holding) as from their higher standards of living, a misfortune like a fire or flood, bringing an increase in expenses or a drop in revenue, could put a domain in debt to the city rice-brokers who handled its finances. Once in debt, neither the individual samurai nor the shogun himself found it easy to recover.
It was difficult for individual samurai overlords to increase their income because the amount of rice that farmers could be made to pay in taxes was not unlimited, and since the income of Japan’s central government consisted in part of taxes collected by the shogun from his huge domain, the government too was constrained. Therefore, the Tokugawa shoguns began to look to other sources for revenue. Cash profits from government-owned mines were already on the decline because the most easily worked deposits of silver and gold had been exhausted, although debasement of the coinage had compensated for the loss. Opening up new farmland was a possibility, but most of what was suitable had already been exploited and further reclamation was technically unfeasible. Direct taxation of the samurai themselves would be politically dangerous. This left the shoguns only commerce as a potential source of government income.
Most of the country’s wealth, or so it seemed, was finding its way into the hands of city merchants. It appeared reasonable that they should contribute part of that revenue to ease the shogun’s burden of financing the state. A means of obtaining such revenue was soon found by levying forced loans, known as goyo-kin; although these were not taxes in the strict sense, since they were irregular in timing and arbitrary in amount, they were high in yield. Unfortunately, they pushed up prices. Thus, regrettably, the Tokugawa shoguns’ search for solvency for the government made it increasingly difficult for individual Japanese who lived on fixed stipends to make ends meet.

How many really suffer as a result of labor market problems? This is one of the most critical yet contentious social policy questions. In many ways, our social statistics exaggerate the degree of hardship. Unemployment does not have the same dire consequences today as it did in the 1930’s when most of the unemployed were primary breadwinners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the overwhelming majority are from multiple-earner, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies.
Yet there are also many ways our social statistics underestimate the degree of labor-market-related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in-kind transfers does not necessarily mean that those failing in the labor market are adequately protected.
As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of labor market problems number in the hundreds of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate—that the existing poverty, employment, and earnings statistics are inadequate for one their primary applications, measuring the consequences of labor market problems.
1.     Which of the following is the principal topic of the passage?

(B) unemployment now has less severe effects
(C) social programs are more needed now
(D) there now is a greater proportion of elderly and handicapped people among those in povertyB

4.     Which of the following proposals best responds to the issues raised by the author?
(A) Innovative programs using multiple approaches should be set up to reduce the level of unemployment.
(B) A compromise should be found between the positions of those who view joblessness as an evil greater than economic control and those who hold the opposite view.
(C) New statistical indices should be developed to measure the degree to which unemployment and inadequately paid employment cause suffering.
(D) Consideration should be given to the ways in which statistics can act as partial causes of the phenomena that they purport to measure.C
(E) The labor force should be restructured so that it corresponds to the range of job vacancies.
5.     The author’s purpose in citing those who are repeatedly unemployed during a twelve-month period is most probably to show that
(A) there are several factors that cause the payment of low wages to some members of the labor force
(B) unemployment statistics can underestimate the hardship resulting from joblessness
(C) recurrent inadequacies in the labor market can exist and can cause hardships for individual workers
(D) a majority of those who are jobless at any one time to not suffer severe hardshipB
(E) there are fewer individuals who are without jobs at some time during a year than would be expected on the basis of monthly unemployment figures
6.     The author states that the mitigating effect of social programs involving income transfers on the income level of low-income people is often not felt by
(A) the employed poor
(B) dependent children in single-earner families
(C) workers who become disabled
(D) retired workersA
(E) full-time workers who become unemployed
7.     According to the passage, one factor that causes unemployment and earnings figures to overpredict the amount of economic hardship is the
(A) recurrence of periods of unemployment for a group of low-wage workers
(B) possibility that earnings may be received from more than one job per worker
(C) fact that unemployment counts do not include those who work for low wages and remain poor
(D) establishment of a system of record-keeping that makes it possible to compile poverty statisticsE
(E) prevalence, among low-wage workers and the unemployed, of members of families in which others are employed
8.     The conclusion stated in lines 33-39 about the number of people who suffer as a result of forced idleness depends primarily on the point that
(A) in times of high unemployment, there are some people who do not remain unemployed for long
(B) the capacity for self-support depends on receiving moderate-to-high wages
(C) those in forced idleness include, besides the unemployed, both underemployed part-time workers and those not actively seeking work
(D) at different times during the year, different people are unemployedD
(E) many of those who are affected by unemployment are dependents of unemployed workers
9.     Which of the following, if true, is the best criticism of the author’s argument concerning why poverty statistics cannot properly be used to show the effects of problems in the labor market?
(A) A short-term increase in the number of those in poverty can indicate a shortage of jobs because the basic number of those unable to accept employment remains approximately constant.
(B) For those who are in poverty as a result of joblessness, there are social programs available that provide a minimum standard of living.
(C) Poverty statistics do not consistently agree with earnings statistics, when each is taken as a measure of hardship resulting from unemployment.
(D) The elderly and handicapped categories include many who previously were employed in the labor market.A

(E) Since the labor market is global in nature, poor workers in one country are competing with poor workers in another with respect to the level of wages and the existence of jobs.

The fossil remains of the first flying vertebrates, the pterosaurs, have intrigued paleontologists for more than two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider (hang-glider: n. 悬挂式滑翔机) and had wingspans from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were—reptiles or birds—are among the questions scientists have puzzled over.
Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a wing-like membrane. The other fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger, and with it the wing, could only turn upward in an extended inverted V-shape along each side of the animal’s body.
The pterosaurs resembled both birds and bats in their overall structure and proportions. This is not surprising because the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced more massively by internal struts.
Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T. H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hairlike fossil material was the first clear evidence that his reasoning was correct.
Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees, or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs’ hind feet resembled a bat’s and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.
1.     It can be inferred from the passage that scientists now generally agree that the
(A) enormous wingspan of the pterosaurs enabled them to fly great distances
(B) structure of the skeleton of the pterosaurs suggests a close evolutionary relationship to bats
(C) fossil remains of the pterosaurs reveal how they solved the problem of powered flight
(D) pterosaurs were reptilesD
(E) pterosaurs walked on all fours
2.     The author views the idea that the pterosaurs became airborne by rising into light winds created by waves as
(A) revolutionary
(B) unlikely
(C) unassailable
(D) probableB
(E) outdated
3.     According to the passage, the skeleton of a pterosaur can be distinguished from that of a bird by the
(A) size of its wingspan
(B) presence of hollow spaces in its bones
(C) anatomic origin of its wing strut
(D) presence of hooklike projections on its hind feetC
(E) location of the shoulder joint joining the wing to its body
4.     The ideas attributed to T. H. Huxley in the passage suggest that he would most likely agree with which of the following statements?
(A) An animal’s brain size has little bearing on its ability to master complex behaviors.
(B) An animal’s appearance is often influenced by environmental requirements and physical capabilities.
(C) Animals within a given family group are unlikely to change their appearance dramatically over a period of time.
(D) The origin of flight in vertebrates was an accidental development rather than the outcome of specialization or adaptation.B
(E) The pterosaurs should be classified as birds, not reptiles.
5.     It can be inferred from the passage that which of the following is characteristic of the pterosaurs?
(A) They were unable to fold their wings when not in use.
(B) They hung upside down from branches as bats do before flight.
(C) They flew in order to capture prey.
(D) They were an early stage in the evolution of the birds.A
(E) They lived primarily in a forest-like habitat.
6.     Which of the following best describes the organization of the last paragraph of the passage?
(A) New evidence is introduced to support a traditional point of view.
(B) Three explanations for a phenomenon are presented, and each is disputed by means of specific information.
(C) Three hypotheses are outlined, and evidence supporting each is given.
(D) Recent discoveries are described, and their implications for future study are projected.B
(E) A summary of the material in the preceding paragraphs is presented, and conclusions are drawn.

Answers @ The right side of question Beware!!

No very satisfactory account of the mechanism that caused the formation of the ocean basins has yet been given. The traditional view supposes that the upper mantle of the earth behaves as a liquid when it is subjected to small forces for long periods and that differences in temperature under oceans and continents are sufficient to produce convection in the mantle of the earth with rising convection currents under the mid-ocean ridges and sinking currents under the continents. Theoretically, this convection would carry the continental plates along as though they were on a conveyor belt (conveyor belt: n. 传送带) and would provide the forces needed to produce the split that occurs along the ridge. This view may be correct: it has the advantage that the currents are driven by temperature differences that themselves depend on the position of the continents. Such a back-coupling, in which the position of the moving plate has an impact on the forces that move it, could produce complicated and varying motions.
On the other hand, the theory is implausible because convection does not normally occur along lines, and it certainly does not occur along lines broken by frequent offsets (an abrupt bend in an object by which one part is turned aside out of line) or changes in direction, as the ridge is. Also it is difficult to see how the theory applies to the plate between the Mid-Atlantic Ridge and the ridge in the Indian Ocean. This plate is growing on both sides, and since there is no intermediate trench, the two ridges must be moving apart. It would be odd if the rising convection currents kept exact pace with them. An alternative theory is that the sinking part of the plate, which is denser than the hotter surrounding mantle, pulls the rest of the plate after it. Again it is difficult to see how this applies to the ridge in the South Atlantic, where neither the African nor the American plate has a sinking part.
Another possibility is that the sinking plate cools the neighboring mantle and produces convection currents that move the plates. This last theory is attractive because it gives some hope of explaining the enclosed seas, such as the Sea of Japan. These seas have a typical oceanic floor, except that the floor is overlaid by several kilometers of sediment. Their floors have probably been sinking for long periods. It seems possible that a sinking current of cooled mantle material on the upper side of the plate might be the cause of such deep basins. The enclosed seas are an important feature of the earth’s surface, and seriously require explanation because, in addition to the enclosed seas that are developing at present behind island arcs, there are a number of older ones of possibly similar origin, such as the Gulf of Mexico, the Black Sea, and perhaps the North Sea.
