OG 三空题目GRE Verbal Reasoning Practice QuestionsSET 3 Discrete Question: Medium4 Richard M. Russell said 52 percent of the nation’s growth since the Second World War had(i) invention. He said, (ii)research, the government’s greatest role in assuring continuing innovation is promoting a strong, modern patent office. “Unless we can(iii)original ideas, we will not have invention.” Mr. Russell said. Speculating on the state of innovation over the next century, several inventors agreed that the future lay in giving children the tools to think creatively and the motivation to invent.5 Statements presented as fact in a patent application are (i)unless a good reason for doubt is found. The invention has only to be deemed “more likely than not” to work in order to receive initial approval. And, although thousands of patents are challenged in court for other reasons, no incentive exists for anyone to expend effort (ii)the science of an erroneous patent. For this reason the endless stream of (iii)devices will continue to yield occasional patent.SET 5 Discrete Question: Hard4 No other contemporary poet’s work has such a well-earned reputation for (i), and there are few whose moral vision is so imperiously unsparing. Of late, however, the almost belligerent demands of his severe and densely forbidding poetry have taken an improbable turn. This new collection is the poet’s fourth book in six years—an ample output even for poets of sunny disposition, let alone for one of such (ii)over the previous 50 years. Yet for all his newfound (iii), his poetry is as thorny as ever.5 Managers who think that strong environmental performance will (i)their company’s financial performance often (ii)claims that systems designed to help them manage environmental concerns are valuable tools. By contrast, managers who perceive environmental performance to be (iii)to financial success may view an environmental management system as extraneous. In either situation, and whatever their perceptions, it is a manager’s commitment to achieving environmental improvement rather than the mere presence of a system that determines environmental performance.6 Philosophy, unlike most other subjects, dose not try to extend our knowledge by discovering new information about the world. Instead it tries to deepen our understanding through(i)what is already closest to us—the experiences, thoughts, concepts, and activities that make up our livesbut that ordinarily escape our notice precisely because they are so familiar. Philosophy begins by finding(ii)the things that are (iii).Practice TestSection 317The most striking thing about the politician is how often his politics have been (i) rather than ideological, as he adapts his political positions at any particular moment to the political realities that constrain him. He does not, however, piously (ii)political principles only to betray them in practice. Rather, he attempts in subtle ways to balance his political self-interest with a (iii), viewing himself as an instrument of some unchanging higher purpose.Section 411What readers most commonly remember about John Stuart Mill’s classic exploration of the liberty of thought and discussion concerns the danger of (i) : in the absence of challenge, one’s opinions, even when they are correct, grow weak and flabby. Yet Mill had another reason for encouraging the liberty of thought and discussion: the danger of partiality and incompleteness. Since one’sopinions, even under the best circumstances, tend to (ii), and because opinions opposed to one’s own rarely turn out to be com pletely (iii), it is crucial to supplement one’s opinions with alternative points of view.20Wills argues that certain malarial parasites are especially (i)because they have more recently entered humans than other species and therefore have had (ii)time to evolve toward (iii). Yet there is no reliable evidence that the most harmful Plasmodium species has been in humans for a shorter time than less harmful species.PREP 三空题目SECTION1-6 The question of (i)in photography has lately become nontrivial. Prices for vintage prints(those make by a photographer soon after he or she made the negative) so drastically (ii)in the 1990s that one of these photographs might fetch a hundred times as much as a nonvintage print of the same image. It was perhaps only a matter of time before someone took advantage ofthe(iii)to peddle newly created “vintage”prints for profit.SECTION34 I’ve long anticipated this retrospective of the artist’s work, hoping it would make(i)judgments about him possible, but greater familiarity with his paintings highlights their inherent (ii)and actually makes one’s assessment(iii).5 Higher energy prices would have many(i)effects on society as a whole. Besides encouraging consumers to be more(ii)in their use of gasoline, they would encourage the development of renewable alternative energy sources that are not(iii)at current prices.6 But they pay little attention to the opposite and more treacherous failing: false certainty, refusing to confess their mistakes and implicitly claiming(i),thereby embarrassing the nation and undermining the Constitution, which established various mechanisms of self-correction on the premise that even the wisest men are sometimes wrong and need, precisely when they find it most(ii), the benefit of(iii)process.原ETS 官网题目It is refreshing to read a book about our planet by an author who does not allow facts to be (i)by politics: well aware of the political disputes about the effects of human activities on climate andbiodiversity, this author does not permit them to(ii)his comprehensive description of what we know about our biosphere. He emphasizes the enormous gaps in our knowledge, the sparseness of our observations, and the(iii), calling attention to the many aspects of planetary evolution that must be better understood before we can accurately diagnose the condition of our planet.2006题目Murray, whose show of recent paintings and drawings is her best in many years, has been eminent hereabouts for a quarter century, although often regarded with (i)__________, but the most (ii)__________ of these paintings (iii)__________ all doubts.2007题目Having displayed his art collection in a vast modernist white space in (i)______ former warehouse, Mr. Saatchi has chosen for his new site its polar opposite, a riverside monument to civic pomposity that once housed the local government. There is nothing (ii)______ about the new location: the building’s design is bureaucratic baroque, (iii)______ style that is as declamatory as a task-force report and as self-regarding as a campaign speech.PRACTICE BOOK 题目That the President manages the economy is an assumption (i)_____ the prevailing wisdom that dominates electoral politics in the United States. As a result, presidential elections have become referenda on the business cycle, whose fortuitous turnings are (ii)_____ the President. Presidents are properly accountable for their executive and legislative performance, and certainly their actions may have profound effects on the economy. But these effects are (iii)_____. Unfortunately, modern political campaigns are fought on the untenable premise that Presidents can deliberately produce precise economic results.Room acoustics design criteria are determined according to the room’s intended use. Music, for example, is best (i)_____ in spaces that are reverberant, a condition that generally makes speech less (ii)_______. Acoustics suitable for both speech and music can sometimes be created in the same space, although the result is never perfect, each having to be (iii)______ to some extent.To the untutored eye the tightly forested Ardennes hills around Sedan look quite (i)______ , (ii)_______place through which to advance a modern army; even with today’s more numerous and better roads and bridges, the woods and the river Meuse form a significant (iii)______.参考答案：CEH AFH CDH BDIBEG CDH BDG BEHADG BEG CFI ADHAEI CEH CEH BEIBEG AEH。

GRE出国考试模拟试题3GRE出国考试模拟试题3GRE出国考试模拟试题3many objects in daily use have clearly been influenced by science, but their form and function, their dimensions and appearance, were determined by technologists artisans, designers, inventors, and engineers---using non-(5) scientific modes of thought. many features and qualities of the objects that a technologist thinks about cannot be reduced to unambiguous verbal descriptions; they are dealt with in the mind by a visual, nonverbal process. in the development of western technology, it has been non- (10)verbal thinking, by and large, that has fixed the outlinesand filled in the details of our material surroundings. pyramids, cathedrals, and rockets exist not because of geometry or thermodynamics, but because they were firsta picture in the minds of those who built them. (15) the creative shaping process of a technologist s mind can be seen in nearly every artifact that exists. for exam-ple, in designing a diesel engine, a technologist might mpress individual ways of nonverbal thinking on the machineby continually using an intuitive sense of right- (20)ness and fitness. what would be the shape of the com- bustion chamber? where should the valves be placed?should it have a long or short piston? such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available (25)space, and not least by a sense of form. some decisions, such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary.design courses, then, should be an essential element (30)in engineering curricula. nonverbal thinking, a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. because perceptive processes are not assumed to entail "hard thinking," nonverbal thought is sometimes seen as a prim-(35)itive stage in the development of cognitive processes and inferior to verbal or mathematical thought. but it is para-doxical that when the staff of the historic american engineering record wished to have drawings made of machines and isometric views of industrial processes for (40)its historical record of american engineering, the onlycollege students with the requisite abilities were not engi- neering students, but rather students attending architec- tural schools.it courses in design, which in a strongly analytical(45)engineering curriculum provide the background requiredfor practical problem- solving, are not provided, we canexpect to encounter silly but costly errors occurring inadvanced engineering systems. for example, early models of high-speed railroad cars loaded with sophisticated(50)controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. absurd ran- dom failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.21.in the passage, the author is primarily concernedwith(a) identifying the kinds of thinking that are used by technologistsb) stressing the importance of nonverbal thinking inengineering design(c) proposing a new role for nonscientific thinkingin the development of technology(d) contrasting the goals of engineers with those of technologists(e) criticizing engineering schools for emphasizing science in engineering curricula22.it can be inferred that the author thinks engineering curricula are(a) strengthened when they include courses in design(b) weakened by the substitution of physical science courses for courses designed to develop mathematical skills(c) strong because nonverbal thinking is still emphasized by most of the courses(d) strong despite the errors that graduates of such curricula have made in the development of automatic control systems(e) strong despite the absence of nonscientific modes of thinking23.which of the following statements best illustrates themain point of lines 1-28 of the passage?(a) when a machine like a rotary engine mal- functions, it is the technologist who is best equipped to repair it.(b) each component of an automobile for example, the engine or the fuel tank has a shape that has been scientifically determined to be best suited to that component s function(c) a telephone is a complex instrument designed by technologists using only nonverbal thought(d) the designer of a new refrigerator should consider the designs of other refrigerators before deciding on its final form.(e) the distinctive features of a suspension bridge reflect its designer s conceptualization as well as the physical requirements of its site.24.which of the following statements would best serve as an introduction to the passage?(a) the assumption that the knowledge incorpor- ated in technological developments must be derived from science ignores the many non- scientific decisions made by technologists. (b) analytical thought is no longer a vital com- ponent in the success of technological development.(c) as knowledge of technology has increased, thetendency has been to lose sight of the impor-tant role played by scientific thought in making decisions about form, arrangement, and texture. (d) a movement in engineering colleges toward a technician s degree reflects a demand for graduates who have the nonverbal reasoning ability that was once common among engineers. (e) a technologist thinking about a machine, reasoning through the successive steps in a dynamic process, can actually turn the machine over mentally.25.the author calls the predicament faced by thehistoric american engineering record "para-doxical" (lines 36-37) most probably because(a) the publication needed drawings that its own staff could not make(b) architectural schools offered but did not require engineering design courses for their students(c) college students were qualified to make the drawings while practicing engineers were not(d) the drawings needed were so complicated that even students in architectural schools had difficulty making them.(e) engineering students were not trained to make thetype of drawings needed to record the development of their own discipline26.according to the passage, random failures in automatic control systems are "not merely trivial aberrations" (lines53) because(a) automatic control systems are designed by engineers who have little practical experience n the field(b) the failures are characteristic of systems designed by engineers relying too heavily on concepts in mathematics(c) the failures occur too often to be taken lightly(d) designers of automatic control systems have too little training in the analysis of mechanical difficulties(e) designers of automatic control systems need more help from scientists who have a better understanding of the analytical problems to be solved before such systems can work efficiently27.the author uses the example of the early models of high-speed railroad cars primarily to(a) weaken the argument that modern engineering systems have major defects because of an absence of designcourses in engineering curricula(b) support the thesis that the number of errors in modern engineering systems is likely to ncrease(c) illustrate the idea that courses in design are the most effective means for reducing the cost of designing engineering systems(d) support the contention that a lack of attention to the nonscientific aspects of design results in poor conceptualization by engineers(e) weaken the proposition that mathematics is a necessary part of the study of designGRE出国考试模拟试题3 相关内容:。

GRE(QUANTITATIVE)综合模拟试卷3(题后含答案及解析)

GRE（QUANTITATIVE）综合模拟试卷3(题后含答案及解析) 题型有：1. 2.1．正确答案：B解析：In this question you are asked to compare the area of a parallelogram with an area of 24, given two side lengths and the measure of one interior angle of the parallelogram. Since the measure of the interior angle given is 125°, you can conclude that the parallelogram is not a rectangle. Recall that the area of a parallelogram is found by multiplying the length of a base by the height corresponding to the base. It is helpful to draw the vertical height from vertex C to base AD of the parallelogram, as shown in the figure below. Note that the newly drawn height is a leg in a newly formed right triangle. The hypotenuse of the triangle is a side of the parallelogram and has length 6. Thus, the leg of the triangle, which is the height of the parallelogram, must be less than the hypotenuse 6. The area of the parallelogram is equal to the length of base AD, which is 4, times the height, which is less than 6. Since the product of 4 and a number less than 6 must be less than 24, the area of the parallelogram must be less than 24. Quantity B is greater than Quantity A, and the correct answer is Choice B.2．正确答案：A解析：From the histogram, you can observe that all of the measurement intervals are the same size, the distribution has a peak at the measurement interval 6-10, and more of the measurement intervals are to the right of the peak than are to the left of the peak. Since in the histogram the 95 measurements have been grouped into intervals, you cannot calculate the exact value of either the average or the median; you must compare them without being able to determine the exact value of either one. The median of the 95 measurements is the middle measurement when the measurements are listed in increasing order. The middle measurement is the 48th measurement. From the histogram, you can see that the measurement interval 1-5 contains the first 15 measurements, and the measurement interval 6-10 contains the next 35 measurements(that is, measurements 16 through 50). Therefore, the median is in the measurement interval 6-10 and could be 6, 7, 8, 9, or 10. Estimating the average of the 95 measurements is more complicated. Since you are asked to compare the average and the median, not necessarily to calculate them, you may askyourself if you can tell whether the average is greater than or less than the median. Note that visually the measurements in the first three measurement intervals are symmetric around the measurement interval 6-10, so you would expect the average of the measurements in just these three measurement intervals to lie in the 6-10 measurement interval. The 30 measurements in the remaining four measurement intervals are all greater than 10, some significantly greater than 10. Therefore, the average of the 95 measurements is greater than the average of the measurements in the first three measurementintervals, probably greater than 10. At this point it seems likely that the average of the 95 measurements is greater than the median of the 95 measurements. It turns out that this is true. To actually show that the average must be greater than 10, you can make the average as small as possible and see if the smallest possible average is greater than 10. To make the average as small as possible, assume that all of the measurements in each interval are as small as possible. That is to say, all 15 measurements in the measurement interval 1-5 are equal to 1, all 35 measurements in the measurement interval 6-10 are equal to 6, etc. Under this assumption, the average of the 95 measurements isThe value of the smallest possible average,1,015/95, is greater than 10. Therefore, since the average of the 95 measurements is greater than 10 and the median is in the measurement interval 6-10, it follows that the average is greater than the median, and the correct answer is Choice A3．正确答案：D解析：One way to approach this question is to plug in numbers for the variables and see what the relationship between the two quantities is for each of the numbers you plug in. If you plug in x = 2, you see that Quantity A is 3x+1= 33 or 27, and Quantity B is 4x = 42, or 16. In this case, Quantity A is greater than Quantity B. If you plug in x = 3, you see that Quantity A is 3x+1 = 34, or 81, and Quantity B is 4x= 43, or 64. In this case, Quantity A is greater than Quantity B. If you plug in x = 4, you see that Quantity A is 3x+1 = 35 or 243, and Quantity B is 4x = 44, or 256. In this case, Quantity B is greater than Quantity A. Since for x = 2 and for x= 3, Quantity A is greater than Quantity B, and for x= 4, Quantity B is greater than Quantity A, it follows that the relationship between the two quantities cannot be determined. The correct answer is Choice D. Since both quantities are algebraic expressions, another way to approach this problem is to set up a placeholder relationship between the two quantities and simplify it to see what conclusions you can draw.For any value of x, the value of 3x is positive, so dividing by 3x does not change any inequality that could be put in the placeholder. Since each step in this simplification is reversible, this reduces the problem to comparing 3 with ;(4/3)x. You can see that because 4/3 is greater than 1, the value of(4/3)x becomes greater as x becomes larger. In particular, it is greater than 3 for large enough values of x.For the smallest value of x, x = 2, the relationship is(4/3)2= 16/9 To say that the value 650 is at the 60th percentile of the distribution means, graphically, that 60 percent of the area between the normalcurve and the horizontal axis lies to the left of the vertical line segment at 650. To say that 850 is at the 90th percentile of the distribution means that 90 percent of the area between the normal curve and the horizontal axis lies to the left of the vertical line segment at 850. The value 750 is halfway between 650 and 850. However, because the curve is decreasing in that interval, the area between 650 and 750 is greater than the area between 750 and 850. Since the value at the 75th percentile should divide in half the area between the value at the 60th percentile(650)and the value at the 90th percentile(850), this value is closer to 650 than to 850. Thus you can conclude that Quantity A, the value at the 75th percentile of the distribution of X, is less than Quantity B. The correct answer is Choice B.6．正确答案：C解析：Set S consists of all integers from 1 to 80, except those that are equal to the square of an integer. So, Quantity A, the number of integers in set S, is equal to the number of positive integers that are less than 81 minus the number of positive integers less than 81 that are equal to the square of an integer. Clearly, there are 80 positive integers that are less than 81. One way to determine the number of positive integers less than 81 that are squares of integers is by noticing that 81 is equal to 92 and concluding that the squares of the integers from 1 to 8 are all positive integers that are less than 81. You can also draw this conclusion by squaring each of the positive integers, beginning with 1, until you get to an integer n such that n2 is greater than or equal to 81. Either way, there are 8 positive integers less than 81 that are squares of integers. Therefore, the number of integers in set S is 80 - 8, or 72, which is equal to Quantity B. So Quantity A is equal to Quantity B, and the correct answer is Choice C.7．A manager is forming a 6-person team to work on a certain project. From the 11 candidates available for the team, the manager has already chosen 3 to be on the team. In selecting the other 3 team members, how many different combinations of 3 of the remaining candidates does the manager have to choose from?A．6B．24C．56D．120E．462正确答案：C解析：To determine the number of different combinations of 3 of the remaining candidates that the manager has to choose from, you first have to know the number of remaining candidates. Since you know that the manager has already chosen 3 of the 11 candidates to be on the team, it is easy to see that there are 8 remaining candidates. Now you need to count how many different combinations of 3 objects can be chosenfrom a group of 8 objects. If you remember the combinations formula, you know that the number of combinations is(which is denoted symbolically asor). You can then calculate the number of different combinations of 3 of the remaining candidates as follows.The correct answer is Choice C.8．Which of the following could be the grap>h of all values of x that satisfy the inequality[*]?[*]A．B．C．D．E．正确答案：C解析：To determine which of the graphs is the correct answer, you first need to determine all values of x that satisfy the inequality. To do that you need to simplify the inequality until you isolate x. You can begin by multiplying both sides of the inequality by 3 to obtain(3)(2 - 5x)-(6x - 5). Note that when you multiply by 3, the right-hand side of the inequality becomes -(6x - 5), not -6x - 5. The rest of the simplification is as follows.Note that when an inequality is multiplied(or divided)by a negative number, the direction of the inequality reverses. The graphs in the answer choices are number lines on which only the number 0 is indicated. Therefore, you do not need to locate 1/9 on the number line; it is nough to know that 1/9 is a positive number. Choice C is the only choice in which the shaded part of the line is equal to or greater than a positive number. Therefore, the correct answer is Choice C.9．If 1+x + x2 + x3 = 60, then the average(arithmetic mean)of x, x2, x3 , and x4 is equal to which of the following?A．12xB．15xC．20xD．30xE．60x正确答案：B解析：A quick inspection of the answer choices shows that it is not necessary to solve the equation 1 + x + x2 + x3 = 60 for x to answer this question. You are being asked to express the average of the four quantities x, x2, x3, and x4 in terms of x. To express this average in terms of x, you need to add the 4 quantities and divide the result by 4; that is,.The only information given in the question is that the sum of the 4 quantities, 1 +x+ x2+ x3, is 60, so you need to think of a way to use this information to simplify the expression.Note that the numerator of the fraction is a sum of 4quantities, each of which has an x term raised to a power. Thus, the expression in the numerator can be factored as x + x2+ x3+ x4= x(1+ x + x2+ x3). By using the information in the question, you can make the following simplification.Therefore, the correct answer is Choice B.10．Parallelogram OPQR lies in the xy-plane, as shown in the figure above. The coordinates of point P are(2,4)and the coordinates of point Q are(8, 6). What are the coordinates of point R ?A．(3,2)B．(3,3)C．(4,4)D．(5,2)E．(6,2)正确答案：E解析：Since OPQR is a parallelogram, line segments PQ and OR have the same length and the same slope. Therefore, in the figure above, PQM and ORN arc congruent right triangles. From the coordinates of P and Q, the lengths of the legs of triangle PQM are PM = 8 - 2 = 6 and QM = 6-4 = 2. Thus, the lengths of the legs ON and RN of triangle ORN are also 6 and 2, respectively. So the coordinates of point R are(6, 2). The correct answer is Choice E.11．The relationship between the area A of a circle and its circumference C is given by the formula A = kC2, where k is a constant. What is the value of k ?A．B．C．1/4D．2πE．4π2正确答案：A解析：One way to approach this problem is to realize that the value of the constant k is the same for all circles. Therefore, you can pick a specific circle and substitute the circumference and the area of that particular circle into the formula and calculate the value of k. Say, for example, that you pick a circle with radius 1. The area of the circle is n and the circumference of the circle is 2π. Inserting these values into the formula gives n = k(2π)2. Solving this equation for k gives k=, and the correct answer is Choice A. Another way to approach the problem is to express A and C in terms of a common variable and then solve the resulting equation for k. Recall the commonly used formulas for the area and the circumference of a circle: A = πr2 and C = 2πr. Note that in these formulas, both A and C are expressed in terms of the radius r. So, in the formula A = kC2, you can substitute expressions for A and C in terms of r. Substituting πr2 for A and 2πr for C gives πr2 = k(2πr)2. Now you can determine the value of k by solving the equation for k as follows.The correct answer is Choice A.12．The sequence of numbers a1,a2,a3,...,an,... is defined byfor each integer n1. What is the sum of the first 20 terms of this sequence?A．B．C．D．E．正确答案：B解析：This question asks for the sum of the first 20 terms of the sequence. Obviously, it would be very time-consuming to write out the first 20 terms of the sequence and add them together, so it is reasonable to try to find a more efficient way to calculate the sum. Questions involving sequences can often be answered by looking for a pattern. Scanning the answer choices and noting that they contain fractions with denominators 2, 20, 21, and 22, and nothing in between, seems to confirm that looking for a pattern is a good approach to try. To look for a pattern, begin by adding the first two terms of the sequence.Now, if you add the first three terms of the sequence, you getNote that you can simplify the sum by canceling the fraction 1/3; that is, the sum of positive 1/3 and negative 1/3 is 0.If you add the first four terms, you getAgain, you can simplify the sum by canceling. This time, you can cancel the fractions 1/3 and 1/4.If you write out the next two sums and simplify them, you will see that they areWorking with the sums makes it clear that this pattern continues to hold as you add more and more terms of the sequence together and that a formula for the sum of the first k terms of the sequence isTherefore, the sum of the first 20 terms of the sequence is equal toThe correct answer is Choice B.13．The table above shows the frequency distribution of the values of a variable Y. What is the mean of the distribution?Give your answer to the nearest 0.01.______正确答案：1.29解析：The mean of the distribution of the variable Y is the sum of all the values of Y divided by the number of values of Y. However, before you begin the summing process, you need to understand how the information is presented in the question. Information about the variable is given in a table, where any repetitions of values have been summarized in the column labeled “Frequency.”Reading from the table, you can see that the value 1/2 occurs twice, the value 3/4 occurs seven times, and so on. To sum all the values of Y, you could add the value - twice, add the value 3/4 seven times, and continue the addition process in this manner. It is easier, however, to multiply the values by their corresponding frequencies and then sum the individual products, as shown below.To find the average, you need to divide the sum, 44, by the number of values of Y. The number of values can be found by looking at the columnof frequencies in the table. The sum of the numbers in this column, 2 + 7 + 8 + 8 + 9, or 34, is the number of values of Y. Thus, the mean of the distribution is 44/34, which, as a decimal, equals 1.2941….Rounded to the nearest 0.01, the correct answer is 1.29.14．Let S be the set of all positive integers n such that n2 is a multiple of both 24 and 108. Which of the following integers are divisors of every integer n in S ?Indicate all such integers.A．12B．24C．36D．72正确答案：A，C解析：To determine which of the integers in the answer choices is a divisor of every positive integer n in S, you must first understand the integers that are in S. Note that in this question you are given information about n2, not about n itself. Therefore, you must use the information about n2 to derive information about n. The fact that n2 is a multiple of both 24 and 108 implies that n2 is a multiple of the least common multiple of 24 and 108. To determine the least common multiple of 24 and 108, factor 24 and 108 into prime factors as(23)(3)and(22)(33), respectively. Because these are prime factorizations, you can conclude that the least common multiple of 24 and 108 is(23)(33). Knowing that n2 must be a multiple of(23)(33)does not mean that every multiple of(23)(33)is a possible value of n2, because n2 must be the square of an integer. The prime factorization of a square number must contain only even exponents. Thus, the least multiple of(23)(33)that is a square is(24)(34). This is the least possible value of n2, and so the least possible value of n is(22)(32), or 36. Furthermore, since every value of n2 is a multiple of(24)(34), the values of n are the positive multiples of 36; that is, S = {36, 72, 108, 144, 180,...}. The question asks for integers that are divisors of every integer n in S, that is, divisors of every positive multiple of 36. Since Choice A, 12, is a divisor of 36, it is also a divisor of every multiple of 36. The same is true for Choice C, 36. Choices B and D, 24 and 72, are not divisors of 36, so they are not divisors of every integer in S. The correct answer consists of Choices A and C.15．The range of the heights of the female students in a certain class is 13.2 inches, and the range of the heights of the male students in the class is 15.4 inches.Which of the following statements individually provide(s)sufficient additional information to determine the range of the heights of all the students in the class?Indicate all such statements.A．The tallest male student in the class is 5.8 inches taller than the tallest female student in the class.B．The median height of the male students in the class is 1.1 inches greater than the median height of the female students in the class.C．The average(arithmetic mean)height of the male students in the class is 4.6inches greater than the average height of the female students in the class.正确答案：A解析：Choice A tells you that the tallest male student is 5.8 inches taller than the tallest female student. You can combine this information with the given information about the male and female height ranges to place four students—the shortest male, the shortest female, the tallest male, and the tallest female—in relative order according to height, as shown in the figure below. You can see from the figure that the tallest student must be a male and the shortest student must be a female. You can also see the difference in height between those two students, which is the range of the heights of the entire class. Therefore, Choice A provides sufficient additional information to determine the range. Choice B provides information about one of the centers of the data—the median; it does not say anything about how spread out the data are around that center. You are given that the median height of the males is 1.1 inches greater than that of the females. First note that it is possible for two different sets of data to have the same median but have very different ranges. Choice B gives the difference between the medians of the male heights and the female heights, without giving the actual medians. However, even if you knew the medians, the fact that the ranges can vary widely indicates that the range of the heights of the entire class can also vary widely. It is possible to construct examples of heights of students that satisfy all of the information in the question and in Choice B but have different ranges for the heights of the entire class. Here are two such examples, each of which has only three females and three males. Although the examples are small, they illustrate the fact that the range of the heights of the entire class can vary. In both examples, the range of female heights is 13.2, the range of male heights is 15.4, and the difference between the median heights is 1.1 inches.Example 1Female heights: 50.0 56.6 63.2 which have a median of 56.6 Male heights: 50.0 57.7 65.4 which have a median of 57.7 Range of heights of entire class: 15.4Example 2Female heights: 50.0 56.6 63.2 which have a median of 56.6 Male heights: 51.0 57.7 66.4 which have a median of 57.7 Range of heights of entire class: 16.4Therefore, Choice B does not provide sufficient additional information to determine the range of the heights of the entire class. Choice C provides information about another center of the data—the average. You are given that the average height of the males is 4.6 inches greater than that of the females. However, like Choice B, the statement gives no information about how spread out the data are around that center. Again, it is possible for two different sets of data to have the same average but have very different ranges. Examples similar to the two examples above can be constructed that satisfy all of the information in the question and in Choice C but have different ranges for the heights of the entire class. Therefore, Choice C does not provide sufficient additional information to determine the range of the heights of the entire class. The correct answer consists of Choice A.。

This “occupational unionism ”　differed substantially from the “worksite unionism ”　prevalentamong factory workers.

By focusing on a limited geographical area in order to gather in-depth information, the authors have avoided the methodological pitfalls that have plagued earlier research on homework. Their findings disprove accepted notions about homeworkers: that they are unqualified for other jobs and that they use homework as a short-term strategy for dealing with child care. The authors conclude that the persistence of homework cannot be explained by appeal to such notions, for in fact, homeworkers do not differ sharply from other employed women. Most homeworkers would prefer to work outside the home butare constrained from doing so by lack of opportunity.

These stars, of more than a few solar masses, evolve, in general, much more rapidly than does a star like the Sun. Moreover, it is just these more massive stars whose collapse does not halt at intermediate stages (that is, as white dwarfs or neutron stars). Instead, the collapse continues until a singularity (an infinitely dense concentration of matter) is reached. It would be wonderful to observe a singularity and obtain direct evidence of the undoubtedly bizarre phenomena that occur near one. Unfortunately in most cases a distant observer cannot see the singularity; outgoing light rays are dragged back by gravity so forcefully that even if they could start out within a few kilometers of the singularity, they would end up in the singularity itself6. the passage suggests which of the following about the Sun?(A) the Sun could evolve to a stage of collapse that is less dense than a singularity.(B) in the Sun, the inward force of gravity is balanced by the generation of heat.(C) the sun emits more observable light than does a white dwarf or a neutron star.7. which of the following sentences would most probably follow the last sentence of the passage?(A) thus, a physicist interested in studying phenomena near singularities would necessarily hope to find a singularity with a measureable gravitational field.(B) accordingly, physicists to date have been unable to observe directly any singularity.(C) it is specifically this startling phenomenon that has allowed us to codify the scant information currently available about singularities.(D) moreover, the existence of this extra ordinary phenomenon is implied in the extensive reports of several physicists.the structure of a singularity.Questions 8 to 9 are based on the following passage.The transfer of heat and water vapor from the ocean to the air above it depends on a disequilibrium at the interface of the water and the air. Within abouta millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor. But the differences, however small, are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water-vapor content. The air is mixed by means of turbulence that depends on the wind for its energy. As wind speed increases, so does turbulence, and thus the rate of heat and moisture transfer. Detailed understanding of this phenomenon awaits further study. An interacting—and complicating—phenomenon is wind-to-water transfer of momentum that occurs when waves are formed. When the wind makes waves, it transfers important amounts of energy—energy that is therefore not available to provide turbulence.8. according to the passage, wind over the ocean generally does which of the following?(A) causes relatively cool, dry air to come into proximity with the ocean surface.(B) maintains a steady rate of heat and moisture transfer between the ocean and the air.(C) causes frequent changes in the temperature of the wa t er at the ocean’s surface.9. the passage suggests that if on a certain day the wind were to decrease until there was no wind at all which of he following would occur?(A) the air closest to the ocean surface would become saturated with water vapor.(B) the air closest to the ocean surface would be warmer than the water(C) the amount of moisture in the air closest to the ocean surface would decrease.(D) the rate of heat and moisture transfer would increase.(E) the air closest to the ocean would be at the same temperature as air higher up.For Questions 10 to 13, select the two answer choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.10.

Although these molecules allow radiation at visible wavelength, where most of the energy of sunlight is concentrated, topass through, they absorb some of the longer-wavelength, infrared emissions radiated from the Earth’s surface, radiation that would otherwisebe transmitted back into space. For the Earth to maintain a constant average temperature,such emissions from the planet must balance incoming solar radiation. Ifthere were no carbon dioxide in the atmosphere, heat would escapefrom the Earth much more easily. The surface temperature would be somuch lower that the oceans might be a solid mass of ice.Today, h owever, the potential problem is too much carbon dioxide. The burning of fossil fuels and the clearing of forests have increased atmospheric carbon dioxide by about 15 percent in the last hundred years, and we continue to add carbon dioxide to the atmosphere. Could the increase in carbon dioxide cause a global rise in average temperature, and could such a rise have serious consequences for human society? Mathematical models that allow us to calculate the rise in temperature as a function of the increase indicate that the answer is probably yes.Under present conditions a temperature of -18 ℃can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude (called the radiating level), the temperature increases by about 6 ℃per kilometer approaching the Earth’s surface, where the average temperature is about 15 ℃. An increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide to absorb infrared radiation. As the capacity of the atmosphere to absorb infrared radiation increases, t he radiating level and the temperature of the surface must rise.One mathematical model predicts that doubling the atmospheric carbon dioxide would raise the global mean surface temperature by 2.5 ℃. This model assumes that the s relative humidity remains constant and the temperature decreases with atmosphere’altitude at a rate of 6.5 ℃per kilometer. The assumption of constant relative humidity is important,because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelength. Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises. Therefore, more infrared radiationsurface. The resultant warming at would be absorbed and reradiated back to the Earth’sreflectivity. the surface could be expected to melt snow and ice, reducing the Earth’ｓMore solar radiation would then be absorbed, leading to a further increase in temperature.14. according to the passage, the greatest part of the solar energy that reaches the Earth is(A) concentrated in the infrared spectrum(B) concentrated at visible wavelengths(C) absorbed by carbon dioxide molecules(D) absorbed by atmospheric water vapor(E) reflected back to space by snow and ice15. according to the passage, atmospheric carbon dioxide performswhich of the following functions(A) absorbing radiation at visible wavelengths(B) absorbing infrared radiation(C) absorbing outgoing radiation from the Earth16. select a sentence in the third or the last paragraph whichindicts the premise of the mathematical model mentioned in the passage?17. When school administrators translate educational research into a standardized teaching program and mandate its use by teachers, students learn less and learn less well than they did before, even though the teachers are the same. The translation by the administrators of theory into prescribed practice must therefore be flawed.The argument above is based on which of the following assumptions?A. teachers differ in their ability to teach in accordance with standardized programs.B. the educational research on which the standardized teaching programs are based is sound.C. researchers should be the ones to translate their own research into teaching programs.D. the ways in which teachers choose to implement the programs are ineffective.E. the level of student learning will vary from state to state.18. A common defense of sport hunting is that it serves a vital wildlife-management function, without which countless animals would succumb to starvation and disease. This defense leads to the overly hasty conclusion that sport hunting produces a healthier population of animals.Which of the following, if true, best supports the author’s claim that sport hunting does not necessarily produce a healthier population of animals?A. for many economically depressed families, hunting helps keep food on the table.B. wildlife species encroach on farm crops when other food supplies become scarce.C. overpopulation of a species causes both strong and weak animals to suffer.D. sport hunters tend to pursue the biggest and healthiest animals in a population.E. many people have strong moral objections to killing a creature for any reason other than self-defense.For Questions 19 to 20, select one entry for each blank from the corresponding columnof choices.

GRE(VERBAL)综合模拟试卷3(题后含答案及解析)

GRE（VERBAL）综合模拟试卷3(题后含答案及解析) 题型有：1. PART ONEPART ONE （Time：30 minutes 38 Questions）SECTION 1Directions: Each sentence below has one or two blanks, each blank indicating that something has been omitted. Beneath the sentence are five lettered or sets of words. Choose the word or set of words for each blank that best fits the meaning of the sentence as a whole.1．For some time now,______has been presumed not to exist: the cynical conviction that everybody has an angle is considered wisdom.A．B．C．D．E．正确答案：D解析：The colon indicates that the second part of the sentence will explain the first part. The missing word will describe the opposite of the cynical conviction that “everybody has an angle,” that is, that each person is concerned primarily with his or her own interests. Since “disinterestedness” means lack of self-interest, Choice D is correct. None of the other answer choices means something that is contrasted with or opposed to being primarily concerned with one’s own interests.2．Human nature and long distances have made exceeding the speed limit a (i)______in the state, so the legislators surprised no one when, acceding to public demand, they(ii)______increased penalties for speeding.A．B．C．D．E．正确答案：B解析：The reference to human nature and long distances suggest that it is rather routine for drivers to exceed the speed limit in this state. “Cherished tradition” best fits this context for Blank(i), since there is nothing in the sentence to suggest that speeding here is “controversial”or “disquieting.”In Blank(ii)we need to consider what the legislature would do that would surprise no one with regard to increased penalties for speeding. Given what we have learned so far, “rejected”is the best answer; it would be surprising il the legislature “endorsed”or even “considered”increased penalties for speeding. Thus the correct answer is cherished tradition(Choice B)and rejected(Choice F).3．Serling’s account of his employer’s reckless decision making(i)______that company’s image as(ii)______bureaucracy full of wary managers.A．B．C．D．E．正确答案：A解析：The correct answer for Blank(i)must support, or at least be consistent with, the contrast between Serling’s account, which emphasizes the recklessness of the company’s decision making, and the company’s image, that of a bureaucracy full of wary managers. For Blank(i), “belies” is the best choice since Serling’s account would certainly belie or contradict the company’s image. “Exposes” makes little sense since the image presumably is already out in the open, and there is nothing in the sentence that suggests Serling’s account “overshadows” the company’s image. As for Blank(ii), “a cautious” is the most logical choice. Neither “an injudicious” nor “a disorganized”makes sense in Blank(ii)as they both go against the notion of wariness.4．No other contemporary poet’s work has such a well-earned reputation for (i)______, and there are few whose moral vision is so imperiously unsparing. Of late, however, the almost belligerent demands of his severe and densely forbidding poetry have taken an improbable turn. This new collection is the poet’s fourth book in six years—an ample output even for poets of sunny disposition, let alone for one of such(ii)______over the previous 50 years. Yet for all his newfound(iii)______, his poetry is as thorny as ever.A．B．C．D．E．正确答案：C解析：Since the author of the paragraph has described the poet’s reputation as “well-earned,” the correct completion for Blank(i)must be something that is consistent with what the rest of the passage says about the poet’s work. Only “near impenetrability”fulfills this requirement, since the next sentence tells us that the poet’s work is “severe”and “densely forbidding,”which rule out both accessibility and frivolity. The Blank(ii)completion must contrast with “ample output,” and of the available options, only “penitential austerity” does so. Finally, the word in Blank(iii), since it is preceded by “newfound,” must refer to the change that has occurred in the poet’s work. The change the paragraph has described is an increase in output, so “volubility” is the correct choice.5．Managers who think that strong environmental performance will(i)______ their company’s financial performance often(ii)______claims that systems designed to help them manage environmental concerns are valuable tools. By contrast, managers who perceive environmental performance to be(iii)______ to financial success may view an environmental management system as extraneous. In either situation, and whatever their perceptions, it is a managers commitment to achieving environmental improvement rather than the mere presence of a system that determines environmental performance.A．B．C．D．E．正确答案：B解析：The first two sentences introduce two contrasting sets of managers. The managers identified in the second sentence view systems designed to help manage environmental concerns as “extraneous,”suggesting that they would view environmental performance to be “peripheral”(Choice I)to financial performance. The other options for Blank(iii)—“complementary”and “intrinsic”—are not consistent with the idea that environmental management systems are extraneous. With Blank(iii)filled in, we can go back to Blanks(i)and(ii)with greater confidence: “bolster”works best in Blank(i), since the two sets of managers have contrasting views. Blank(ii)is not straightforward—clearly these managers would not “hotly dispute”this claim, but “appropriately acknowledge”is less easily ruled out.“Uncritically accept”makes sense and is confirmed when we look at the final sentence in which the author warns that, in either situation, “the mere presence of a system” is not enough to achieve environmental improvement. In fact, a system is not even necessary. Thus the author of the paragraph does not regard the systems as particularly valuable, ruling out “appropriately acknowledge.”6．Philosophy, unlike most other subjects, does not try to extend our knowledge by discovering new information about the world. Instead it tries to deepen our understanding through(i)______what is already closest to us—the experiences, thoughts, concepts, and activities that make up our lives but that ordinarily escape our notice precisely because they are so familiar. Philosophy begins by finding(ii)______the things that are(iii)______.A．B．C．D．E．正确答案：B解析：The first two sentences present a contrast between extending our knowledge by discovering “new information about the world”—which we are told philosophy does not do —and extending knowledge through some activity involving “things that are closest to us.”The first blank asks us to identify that activity, and although “attainment”makes little sense in context, both “rumination on”and “detachment from” have some appeal. However, the clear implication that philosophy attends to things that ordinarily escape our notice eliminates “detachment from” as a correct answer. Blank(ii)requires something that suggests the importance of familiar things as subjects of philosophical rumination, and “utterly mysterious” does just that. “Essentially irrelevant” and “thoroughly commonplace” do not fit logically since they suggest that these “familiar” things are unimportant. Similarly, Blank(iii)needs to be consistent with the description of those things as familiar and close. “Most prosaic”fits that idea while “refreshingly novel”goes in the other direction. “Somewhat hackneyed”has some plausibility but is too negative given the overall tone of the sentence; there is no indication that those things are in any way trite.SECTION 2Directions: In each of the following questions, a related pair of words or phrases is followed by five lettered pairs of words or phrases. Select the lettered pair that best expresses a relationship similar to that expressed in the original pair.7．The government’s implementation of a new code of ethics appeared intendedto shore up the ruling party’s standing with an increasingly______electorate at a time when the party is besieged by charges that it trades favors for campaign money.A．aloofB．placidC．restiveD．skittishE．tranquil正确答案：C解析：The words filling the blank must be consistent with the idea that the ruling party needs to “shore up” its standing with the electorate. In their own way, Choices A, C, D, and F are consistent with that idea, but only two of these when taken together —”restive”and “skittish”—produce sentences that are alike in meaning. “Aloof”fits the blank reasonably well, but there is no other word offered that is nearly alike in meaning. The same holds for “vociferous.”“Placid”and “tranquil”are similar in meaning but do not fit the context of the sentence.8．Overlarge, uneven, and ultimately disappointing, the retrospective exhibition seems too much like special pleading for a forgotten painter of real but______ talents.A．limitedB．partialC．undiscoveredD．circumscribedE．prosaic正确答案：A解析：The sentence is explaining why the exhibition of the painters work was unsatisfactory, and since it says that the painters talents were real, the word in the blank has to indicate why those talents were not, in the opinion of the author of the sentence, good enough. The words “limited”and “circumscribed”do so and also produce sentences that are alike in meaning, so this pair forms the correct answer. Although “undiscovered”and “hidden”are similar in meaning, they do not make sense in the context of the sentence, since they do not indicate why the painter’s talents were not adequate. Other choices, such as “partial” and “prosaic” might make sense in context, but none of the other choices that meets that criterion also has a companion choice that would produce another sentence alike in meaning. Thus the correct answer is limited(Choice A)and circumscribed(Choice D).9．Newspapers report that the former executive has been trying to keep a low profile since his______exit from the company.A．celebratedB．mysteriousC．long-awaitedD．fortuitousE．indecorous正确答案：E解析：The sentence needs to be completed with a word that suggests a reason for the executive to wish to keep a low profile. The words “indecorous” and “unseemly”both suggest such a reason, and the sentences completed with those two choices are alike in meaning. Therefore, that pair forms the correct answer. Although one might get a sensible sentence by filling the blank with another choice, such as “long-awaited,”none of the other choices that meets that criterion also has a companion choice that would produce another sentence alike in meaning.SECTION 3Directions: Each passage in this group is followed by questions based on its content. After reading a passage, choose the best answer to each question. Answer all questions following a passage on the basis of what is stated or implied in the passage.10．In the United States between 1850 and 1880, the number of farmers continued to increase, but at a rate lower than that of the general population.Which of the following statements directly contradicts the information presented above?A．The number of farmers in the general population increased slightly in the 30 years between 1850 and 1880.B．The rate of growth of the United States labor force and the rate of growth of the general population rose simultaneously in the 30 years between 1850 and 1880.C．The proportion of farmers in the United States labor force remained constant in the 30 years between 1850 and 1880.D．The proportion of farmers in the United States labor force decreased from 64 percent in 1850 to 49 percent in 1880.E．The proportion of farmers in the general population increased from 68 percent in 1850 to 72 percent in 1880.正确答案：E解析：The given sentence indicates that the proportion of farmers in the general population decreased from 1850 to 1880. Choice E says exactly the opposite—that this proportion increased—and therefore it contradicts the passage and is the correct response. Choice A is incorrect because it agrees with the given sentence, and Choices B, C, and D are all incorrect because they refer to the labor force, about which the given sentence says nothing.11．A ten-year comparison between the United States and the Soviet Union in terms of crop yields per acre revealed that when only planted acreage is compared, Soviet yields were equal to 68 percent of United States yields. When total agricultural acreage(planted acreage plus fallow acreage)is compared, however, Soviet yield was 114 percent of United States yield.From the information above, which of the following can be most reliably inferred about United States and Soviet agriculture during the ten-year period?A．A higher percentage of total agricultural acreage was fallow in the United States than in the Soviet Union.B．The United States had more fallow acreage than planted acreage.C．Fewer total acres of available agricultural land were fallow in the Soviet Union than in the United States.D．The Soviet Union had more planted acreage than fallow acreage.E．The Soviet Union produced a greater volume of crops than the United States produced.正确答案：A解析：If crop yield per planted acre was less in the Soviet Union than it was in the United States, yet crop yield per total(planted plus fallow)agricultural acreage was greater in the Soviet Union than it was in the United States, the percentage of the total acreage that was left fallow must have been lower in the Soviet Union than in the United States. Therefore, Choice A is the correct answer. Since the information provided in the paragraph is given in terms of yield per acre, no conclusion can be drawn about actual acreage, so Choices B, C, and D are all incorrect. Similarly, it is impossible to determine the total volume of crops produced in the Soviet Union, so Choice E is incorrect.For hot desert locations with access to seawater, a new greenhouse design generates freshwater and cool air. Oriented to the prevailing wind, the front wall of perforated cardboard, moistened and cooled by a trickle of seawater pumped in, cools and moistens hot air blowing in. This cool, humidified air accelerates plant growth; little water evaporates from leaves. Though greenhouses normally capture the heat of sunlight, a double-layered roof, the inner layer coated to reflect infrared light outward, allows visible sunlight in but traps solar heat between the two layers. This heated air, drawn down from the roof, then mixes with the greenhouse air as it reaches a second seawater-moistened cardboard wall at the back of the greenhouse. There the air absorbs more moisture, which then condenses on a metal wall cooled by seawater, and thus distilled water for irrigating the plants collects.12．It can be inferred that the process described in the passage makes use of which of the following?A．The tendency of hot air to riseB．The directional movement of windC．The temperature differential between the sea and the desert正确答案：B解析：Choices B and C are correct. This question asks the reader which of the three phenomena listed in the answer choices is used in the process described in the passage.Choice A is incorrect: the passage does not indicate that the tendency of hot air to rise is used in the process, and in fact says that heated air is drawn down, not up, as part of the greenhouse design.Choice B is correct: the second sentence describes the orientation of a perforated cardboard wall toward the prevailing wind so that hot air blows in and is moistened.Choice C is correct: the passage describes the use of seawater to cool hot desert air and to provide moisture that is absorbed by heated airand then condensed on a seawater-cooled surface for the purpose of irrigating the plants.13．It can be inferred that the greenhouse roof is designed to allow for which of the following?A．The avoidance of intense solar heat inside the greenhouseB．The entry of sunlight into the greenhouse to make the plants growC．The mixture of heated air with greenhouse air to enhance the collection of moisture正确答案：A解析：All three choices are correct. This question asks the reader which of the three effects listed in the answer choices are intended as part of the design of the greenhouse roof.Choice A is correct: the purpose of the double-layered roof is to trap solar heat before it gets inside the greenhouse proper.Choice B is correct: the coating on the inner layer of the roof allows visible sunlight into the greenhouse.Choice C is correct: the last two sentences of the passage describe how heated air from the roof is drawn down to mix with greenhouse air, resulting in the collection of distilled water for irrigation purposes.Many critics of Emily Bronte’s novel Wuthering Heights see its second part as a counterpoint that comments on, if it does not reverse, the first part, where a romantic reading receives more confirmation. Seeing the two parts as a whole is encouraged by the novel’s sophisticated structure, revealed in its complex use of narrators and time shifts. Granted that the presence of these elements need not argue for an authorial awareness of novelistic construction comparable to that of Henry James, their presence does encourage attempts to unify the novel’s heterogeneous parts. However, any interpretation that seeks to unify all of the novel’s diverse elements is bound to be somewhat unconvincing. This is not because such an interpretation necessarily stiffens into a thesis(although rigidity in any interpretation of this or of any novel is always a danger), but because Wuthering Heights has recalcitrant elements of undeniable power that, ultimately, resist inclusion in an all-encompassing interpretation. In this respect, Wuthering Heights shares a feature of Hamlet.14．According to the passage, which of the following is a true statement about the first and second parts of Wuthering Heights?A．The second part has received more attention from critics.B．The second part has little relation to the first part.C．The second part annuls the force of the first part.D．The second part provides less substantiation for a romantic reading.E．The second part is better because it is more realistic.正确答案：D解析：This question requires the reader to identify which of the given relationships between the novel’s first and second parts is one that is described in the passage. According to the first sentence, the first part of the novel tends to confirm the “romantic”reading more strongly than the second. Therefore, Choice D is correct. Nothing in the passage suggests that critics have paid more attention to the second part, that the two parts have little relation, or that the second part is better. Therefore, Choices A, B, and E are incorrect. Choice C is a more extreme statement than any found in the passage, and therefore it is incorrect.15．Which of the following inferences about Henry James’s awareness of novelistic construction is best supported by the passage?A．James, more than any other novelist, was aware of the difficulties of novelistic construction.B．James was very aware of the details of novelistic construction.C．James’s awareness of novelistic construction derived from his reading of Bronte.D．James’s awareness of novelistic construction has led most commentators to see unity in his individual novels.E．James’s awareness of novelistic construction precluded him from violating the unity of his novels.正确答案：B解析：This question focuses on the passages mention of Henry James and asks what can be inferred from it. The third sentence implies that James represents a very high degree of authorial awareness of novelistic construction and that no such claim is necessarily being made for Bronte. Thus, Choice B is the correct answer. Choice A is incorrect, since the passage does not imply that there are particular difficulties that James understood uniquely among novelists. Choice C is incorrect because the passage does not state or imply that James read Bronte. The passage also does not say anything about commentators’opinions of the unity of James’s works; therefore Choice D is incorrect. Choice E is incorrect because the passage itself offers no information about the unity of James’s novels.16．The author of the passage would be most likely to agree that an interpretation of a novel shouldA．not try to unite heterogeneous elements in the novelB．not be inflexible in its treatment of the elements in the novelC．not argue that the complex use of narrators or of time shifts indicates a sophisticated structureD．concentrate on those recalcitrant elements of the novel that are outside the novel’s main structureE．primarily consider those elements of novelistic construction of which the author of the novel was aware正确答案：B解析：This question requires the reader to determine what can be inferred fromthe passage about its author’s view of the interpretation of novels. Choice A may seem attractive because in the passage the author says that Wuthering Heights has heterogeneous elements that resist inclusion in a unifying interpretive scheme. Choice A is incorrect, however, because the author does not indicate that the unification of different elements is to be avoided in interpretation generally. By contrast, the author’s parenthetical statement about rigidity does present a general warning against inflexibility of interpretation, and it is this that supports Choice B as the correct answer. Choice C is incorrect, as the author actually suggests the contrary of this view in the second sentence of the passage. Although the author mentions recalcitrant elements of Wuthering Heights, there is no suggestion by the author that such elements deserve a special focus in interpretation. Therefore Choice D is incorrect. The author of the passage does not indicate which elements, if any, of novelistic construction are most worthy of consideration. Therefore Choice E is incorrect.17．The author of the passage suggests which of the following about Hamlet?A．Hamlet has usually attracted critical interpretations that tend to stiffen into theses.B．Hamlet has elements that are not amenable to an all-encompassing critical interpretation.C．Hamlet is less open to an all-encompassing critical interpretation than is Wuthering Heights.正确答案：B解析：Choice B is correct. This question asks the reader which of the three statements about Hamlet listed in the answer choices are suggested by the author of the passage.Choice A is incorrect: the passage does not provide information about the characteristics of the usual critical interpretations of Hamlet.Choice B is correct: Hamlet is mentioned only in the final sentence of the passage, which refers to “this respect” in which Hamlet and Wuthering Heights are similar. The previous sentence reveals the point of similarity referred to: Wuthering Heights has elements that resist inclusion in an all-encompassing interpretive framework.Choice C is incorrect: the passage mentions only a feature shared between Hamlet and Wuthering Heights. It does not suggest anything about a difference in their openness to a particular critical interpretation.。

BLANK1 BLANK2 BLANK3 A differ profoundly D reverse G distinction B convergent E conventionality Hequilibrium C slightly differentiate F similarity I dissemination 3. Although some censure became (i)___ during the 1980s, Dahl himself seems to support some of such earlier criticism.

BLANK1 BLANK2 BLANK3 A instructive D a derivative G repair B literal E an insipid Hqualify C organic F an inspired I construct 7. Most psychologists, perplexed by the feelings they acknowledge are aroused by aesthetic experience, have claimed that these emotions are genuine, but different in kind from nonaesthetic emotions. This, however, is (i)___ rather than an empirical observation and consequently lacks explanatory value.
