GRE(ANALYTICAL WRITING)模拟试卷1(题后含答案及解析)

GRE（ANALYTICAL WRITING）模拟试卷1(题后含答案及解析) 题型有：1. Analyze an Issue 2. Analyze an ArgumentAnalyze an Issue1．You will be given a brief quotation that states or implies an issue of general interest and specific instructions on how to respond to that issue. You will then have 30 minutes to plan and compose a response according to the specific instructions. A response to any other issue will receive a score of zero.Make sure that you respond according to the specific instructions and support your position on the issue with reasons and examples drawn from such areas as your reading, experience, observations, and/or academic studies.Trained GRE readers will evaluate your response for its overall quality, based on how well you: Respond to the specific task instructions Consider the complexities of the issue Organize, develop, and express your ideas Support your ideas with relevant reasons and/or examples Control the elements of standard written EnglishBefore you begin writing, you may want to think for a few minutes about the issue and the specific task instructions and then plan your response. Be sure to develop your position fully and organize it coherently, but leave time to reread what you have written and make any revisions you think are necessary. Issue TopicThe best way to teach is to praise positive actions and ignore negative ones.Write a response in which you discuss the extent to which you agree or disagree with the recommendation and explain your reasoning for the position you take. In developing and supporting your position, describe specific circumstances in which adopting the recommendation would or would not be advantageous and explain how these examples shape your position.正确答案：The recommendation presents a view that I would agree is successful most of the time, but one that I cannot fully support due to the “all or nothing”impression it gives. Certainly as an educator I agree fully that the best way to elicit positive response from students is to make use of students’ positive energy and then encourage actions that you would like to see repeated. It is human nature that we all want to be accepted and achieve on some level, and when people in authority provide feedback that we have done something well, the drive to repeat the action that was praised is bound to be particularly strong. This blanket statement would obviously pay dividends in situations in which a teacher desires to have students repeat particular behaviors. For example, if an educator is attempting to teach students proper classroom etiquette, it would be appropriate to openly praise a student who raises his or her hand when wishing to speak or address the class. In such cases, the teacher may also help shape positive behaviors by ignoring a student who is trying to interject without approval from the teacher. In fact, the decision to ignore students who are exhibiting inappropriate behaviors of this type could work very well in this situation, as the stakes are not very high and the intended outcome can likely beachieved by such a method. However, it is important to note here that this tactic would only be effective in such a “low-stakes”situation, as when a student speaks without raising her hand first. As we will discuss below, ignoring a student who hits another student, or engages in more serious misbehaviors, would not be effective or prudent. To expand on this point, it is important for teachers to be careful when working with the second half of this statement, only ignoring negative actions that are not serious. Take for instance a student who is misbehaving just by chatting with a fellow classmate. This student might not be presenting much of a problem and may be simply seeking attention. Ignoring the student might, in fact, be the best solution. Now assume the negative action is the improper administering of chemicals in a science experiment or the bullying of a fellow student. To ignore these negative actions would be absurd and negligent. Now you are allowing a problem to persist, one that could potentially lead to much bigger and more dangerous issues. In a more serious situation, addressing the negative actions quickly and properly could stop the problem it in its tracks. It is for reasons like this that I do not advocate the idea that a teacher can be successful by simply ignoring negative actions. I do, however, greatly support the idea that the central focus of teaching should be to build on and encourage positive actions. However, the author’s all-encompasing statement leaves too many negative possibilities for the classroom. Perhaps a better way to phrase this statement would be to say, “The best way to teach is to praise positive actions and ignore negative ones that are not debilitating to class efficiency or the safety of any individual”. Thus, in the original statement, there are indeed some good intentions, and there could be a lot of merit in adopting its basic principles. Data proves that positive support can substantially increase motivation and desire in students and contribute to positive achievements. In fact, most studies of teaching efficacy indicate that praising positive actions and ignoring negative ones can create a more stable and efficient classroom. It needs to be stressed, however, that this tool is only effective at certain levels of misbehavior. As mentioned above, when the behavior is precipitated by feelings of revenge, power or total self-worthlessness, this methodology will likely not work. It is likely to be very successful, however, when the drive behind the misbehavior is simple attention seeking. In many of these instances, if the teacher demonstrates clearly that inappropriate behavior does not result in the gaining of attention, students are more likely to seek attention by behaving properly. Should the student choose this path, then the ignoring has worked and when the positive behavior is exhibited, then the teacher can utilize the first part of the theory and support or praise this behavior. Now it is much more likely to be repeated. If the student does not choose this path and instead elects to raise the actions to a higher level that presents a more serious issue, then ignorance alone cannot work and other methods must be employed. In conclusion, one can appreciate the credo expressed in this instance, but surely we all can see the potential error of following it through to the extreme.解析：This response receives a 6 for its well-articulated, insightful analysis of the issue. Rather than simply rejecting or accepting the prompt, the writer argues that the recommendation made by the prompt can often be true but is too “all or nothing” tobe endorsed without qualification. The writer turns this idea into an insightful position by providing examples and evidence to fully and persuasively support its nuanced argument. The response offers nicely detailed situations that provide compelling support for a claim that the recommendation can, in fact, work. At the same time, it also highlights the recommendations limits using additional specific, detailed examples. Particularly persuasive is the fourth paragraph, in which the writer compares the impact of ignoring minor behavioral problems like talking in class to the potential costs of ignoring more serious issues like bullying. Thus, the writer recognizes that the prompt’s claim, as well as his/her own, is inevitably dependent on the specific context for its success or failure. Throughout the response, the writer demonstrates the ability to convey ideas fluently and precisely using effective vocabulary and sentence variety. This sentence demonstrates the level of language facility seen throughout the response: “It is human nature that we all want to be accepted and achieve on some level, and when people in authority provide feedback that we have done something well, the drive to repeat the action that was praised is bound to be particularly strong.”Analyze an Argument2．The following appeared in a memorandum from the owner of Movies Galore, a chain of video rental stores.”In order to reverse the recent decline in our profits, we must reduce operating expenses at Movies Galores ten video rental stores. Since we are famous for our special bargains, raising our rental prices is not a viable way to improve profits. Last month our store in downtown Marston significantly decreased its operating expenses by closing at 6:00 P.M. rather than 9:00 P.M. and by reducing its stock by eliminating all movies released more than five years ago. Therefore, in order to increase profits without jeopardizing our reputation for offering great movies at low prices, we recommend implementing similar changes in our other nine Movies Galore stores.”Write a response in which you discuss what questions would need to be addressed in order to decide whether the recommendation is likely to have the predicted result. Be sure to explain how the answers to those questions would help to evaluate the recommendation.正确答案：One question which needs to be addressed before implementing the recommendation is whether there are not other ways to improve profits besides cutting operating expenses. Without proof, the author decides, first, that there are only two viable options for increasing the profits of Movies Galore: raising rental prices, and cutting costs. He rules out the first course, and hence claims the second option must be chosen. But it seems there may be alternative methods of increasing profits, such as initiating advertising campaigns or closing unprofitable Movies Galore locations. Even if it is granted that there are only two options for increasing profitability—cutting costs, and raising rental prices—one might wonder why raising rental prices is so unthinkable. The author implies that because Movies Galore is famous for special bargains, raising the rental prices would eliminate this competitiveadvantage and decrease profitability. However, in making this conclusion, he makes several assumptions without considering questions that need to be addressed. First, he assumes that there is no room to raise current prices and yet maintain lower prices than competitors. One would need to ask if prices could be increased slightly, while keeping them cheap. Even if there is no room for such a strategy, the author assumes that Movies Galore’s reputation for bargain pricing would evaporate if they increased their prices slightly. Perhaps such a reputation would be widespread enough to persist despite a slight increase in prices. And thirdly, even if the reputation for bargains would be eliminated by an increase in prices, the author assumes that Movies Galore cannot change course and be successful in some other way. Perhaps it could instead become known as the store with the friendliest employees. Perhaps it already is, and the author is wrong to believe that a causal relationship between bargain prices and success exists, when the real cause of Movies Galore’s good reputation is entirely independent of its prices. The author needs to answer these questions to convince us that profits are caused by bargains, and not by the other factors that may be involved. Another question that needs to be raised is whether or not the downtown Marston store is truly analogous to the other nine Movies Galore stores. The author seems to assume that because the cost-cutting measures worked at the Marston location, it will work at the others, but this is far from clear. Perhaps the patrons of the other Movies Galore locations would resent such changes in the hours and stock of their local stores. Perhaps the most important question that needs to be asked is whether the Marston location’s changes truly increased profitability. The author writes that the Marston store decreased operating expenses by closing earlier and cutting its stock, but he makes no mention of increased profitability. It is quite possible that the Marston location’s profits decreased as a result of their cost cutting, and this is a question that needs to be addressed. The author then jumps to the conclusion that taking similar measures would increase profitability at other locations, though such a connection has not even been established at the Marston store. Even if the cost-cutting measures increased profitability at the Marston store last month(and a causal relationship, though presumably assumed, is still far from evident), there is no guarantee that such measures would continue to increase profitability over time. One would need to ask: Why not observe how the Marston location’s action affect profitability over several months, before implementing such sweeping changes at every store? A single month is a very short time span, and the habits of customers may change slowly. As word gets around that the Marston store has cut their hours and their selection, they may in fact jeopardize their reputation for offering “great movies at low prices.” After all, the name of the franchise is Movies Galore, and by drastically reducing the available selection, they may alienate their customer base. If, as mentioned above, Movies Galore is famous for more than its great bargains—if customers prefer Movies Galore because of its selections, as well —then such a move may drastically reduce profits overtime. It seems extremely rash to implement such a new and relatively untried strategy at every Movies Galore location, before the effects can be fully observed and interpreted.解析：This outstanding response clearly addresses the specific task directions andpresents a cogent, insightful analysis by discussing specific questions that need to be addressed in order to analyze the argument presented. It is worth noting that although the directions ask for questions, it is not necessary that these be phrased in question form. The response articulately discusses the information needed to evaluate whether the recommendation is likely to have the predicted result and demonstrates how this information would help to evaluate the recommendation. There are many examples of ways in which the writer addresses questions without putting them in question form(e.g., “he assumes that there is no room to raise current prices and yet maintain lower prices than competitors. One would need to ask...” or “it seems there may be alternative methods of increasing profits”). Throughout this response, the writer provides the cogent development typical of a 6 response. For example, the discussion of Movies Galore’s reputation gets at a number of flaws in the argument’s reasoning, making nuanced points(e.g., “Perhaps it could instead become known as the store with the friendliest employees. Perhaps it already is...”)that create a compelling case for the writer’s objections. Transitions are natural, and the paragraphs build on one another, succinctly and completely developing the writer’s points. Because of its compelling and insightful development and fluent and precise language, this response fits all of the bullet points for a score of 6.。

Given that the sites were close to a huge passenger pigeon roost documented by John James Audubon in the nineteenth century and that Cahokians consumed almost every other animal protein source available, Q2the archaeologists conducting the studies concluded the passenger pigeon population had once been very limited before increasing dramatically in post-Columbian America.

Answer all questions following a passage on the basis of what is stated or implied in that passage.lt has been known for many decades that the appear-ance of sunspots is roughly periodic, with an averagecycle of eleven years. Moreover, the incidence of solar flares and the flux of solar cosmic rays, ultraviolet radia-tion, and x-radiation all vary directly with the sunspot (5)cycle. But after more than a century of investigation. the relation of these and other phenomena, known collec-tively as the solar-activity cycle, to terrescrial weather and climate remains unclear. For example. the sunspot cycle and the allied rnagnetic-polarity cycle have been (10)linked to periodicities discerned in records of such vari-ables as rainhll. temperature, and winds. lnvariably,however, the relation is weak. and commonly ofdubious statistical significance. Effects of solar variability over longer terms have also (15)been sought. The absence of recorded sunspot activity in the notes kept by European observers in the late seven-teenth and early eighteenth centuries has led some schol-ars to postulate a brief cessation of sunspot activity atthat time (a period called the Maunder minimum). The (20)Maunder minimum has been linked to a span of unusual cold in Europe extending from the sixteenth to the early nineteenth centuries. The reality of the Maunder mini- mum has yet to be established, however, especially since the records that Chinese naked-eye observers of solar (25)activity made at that time appear to contradict it. Scien-tists have also sought evidence of long-term solar period-icities by examining indirect climatological data, such as fossil recoras of the thickness of ancient tree rings. These studies, however, failed to link unequivocally terrestrial(30)climate and the solar-activity cycle, or even to contirm the cycle's past existenue.If consistPn! and re!iab!egeo!sgigal~-arek-xologiealevidence tracing the solar-activity cycle in the distant past could be found, it might also resolve an important(35)issue in solar physics: how to model solar activity. Cur-rently, chere are two models of solar activity. The tirst supposes that the Sun's internal motions (caused by rotation and convection) interact with its large-scale magnetic field to produce a dynamo. a device in which(40)mechanical energy is converted into the energy of a mag-netic field. ln short. the Sun's large-scale magnetic field is taken to be self-sustaining, so that the solar-activity cycle it drives would be maintained with little overall changc forperhaps billions of years. The alternative(45)exp)anarion supposes that the Sun's large-sca)e magnetic field is a remnant of the field the Sun acquired when it formed, and is not sustained against decay. In this model. the solar mechanism dependent on the Sun'smagnetiC field runs down more quickly. Thus, the char-(50)acteristics of the solar-activity cycle uvuld be expected to change over a long period of time. Modern solar obser-vations span too short a time to reveal whether present cyclical solar aCtivity is a long-lived feature of the Sun,or merely a transient phenomenon.17. The author focuses primarily on(A) presenting two competing scientific theories concerning solaractivity and evaluating geological evidence often cited to support them(B) giving a brief overview of some recent scientifrc developmentsin s'olar physics and assessing their impact on future climatological research(C) discussing the difficulties involved in linkinl: ter- restrialphenomena with solar activity and indicating how resolving that issuecould have an impact on our understanding of solar physics(D) pointing out the futility of a certain line of sci- entific inquiryinto the terrestrial effects of solar activity and recommendine itaaban- donment in favor of purely physics-oriented research(E) outlinine the specific reasons why a problem in solar physics hasnot yet been solved and faulting the overly theoretical approach of modernphysicists.18. Which of th.e following statements about the two models of solaractivity. as they are described in lines 37-55, is accurate?(A) In both modgls cyclical solar activity is regarded as a long-livedfeature of the Sun, persisting with little change over billions of years.(B) Tn both models the solar-activity cycle is hypothesized as beingdependent on the large-scale solar magnetic field.(C) Tn one model the Sun's magnetic fieid is thought to play a role incausing solar activ- ity, whereas in the other model it is not.(D) In one model solar activity is presumed to be unrelated to terrestrial phenomena. whereas in the other model solar activity is thought to have observable effects on the Earth.(E) In one model cycles of solar activity with peri- odicities longer thana few decades are con- sidered to be impossible, whereas in the other model such cycles are predicted.19. According to the passage, late seventeenth- and early eighteenth-century Chinese records are impor- tant for which of the following reasons?(A) They suggest that the data on which the Maunder minimum was predicated were incorrect.(B) They syggest that the Maunder minimum can- not be related to climate.(C) Thcy suggest that the Maunder minimum might be \-'alid only for Europe.(D) They establish the existence of a span of unusu- ally cold weather worldwide at the time of the Maunder minimum.(E) They establish that solar activity at the tirne of the Maunder minimumdid not significantly vary from its present pattern.20. The author implies which of the followine about currently available geological and archaeoloeical evidence concerning the solar-activity cycle?(A) It best supports the model of solar activity described in lines 37-45.(B) It best supports the model of solar activity described in lines 45-52.(C) It is insufficient to confirtn either model of solar activity describedin the third paragraph.(D) It contradicts both models of solar activity as they are presented inthe third paragraph.(E) It disproves the theory that terrestrial weather and solar activitv are linked in some way.21. Tt can be inferred from the passage that the argu- ment in favor of themodel described in lines 37- 45 would be strengthened if which of the followingwere found ta he tme?(A) Episodes of intense volcanic eruptions in the distant past occurred incycles having very long periodicities.(B) At the present time the global level of thunder- storm activity increasesand decreases in cycles with periodicities of approximately 11 years.(C) In the distant past cyclical climatic changes had periodicities of longerthan 200 years.(D) In the last century the length of the sunspot cycle has been known tovary by as much as 2 years from its average periodicity of 11 years.(E) Hundreds of millions of years ago, solar- activity cycles displayed thesame periodicities as do present-day solap-activity cycles.22. lt can be inferred from the passage that Chinese observations of the Sunduring the late seventeenth and early eighteenth centuries(A) are ambiguous BECause most sunspots cannot be seen with the naked eye(B) probably were made under the same weather conditions as those made in Europe(C) are more reliable than European observations . made during this period(D) record some sunspot activity during this period(E) have been employed by scientists seeking to argue that a change in solaractivity occurred during this period.23. It can be inferred from the passage that studies attempting to use tree-ringthickness to locate possi- ble links between solar periodicity and terrestrialclimate are based on which of the following assump- tions?(A) The solar-activity cycle existed in its present form during the time periodin which the tree rings erew.(B) The biological mechanisms causing tree growth are unaffected by short-termweather pat- terns.(C) Average tree-ring thickness varies from species to species.(D) Tree-ring thicknesses reflecr changes in terres- trial climate.(E) Both terrestrial climate and the solar-activity cycle randomly af~ct tree-ring thickness.The common belief of some linguists that eachlanguage is a perfect vehicle for the thoughts of thenation speaking it is in some ways the exact counterpartof the conviction of the Manchester school of economicsthat supply and demand will regulate everything for the(5)best. Just as economists were blind to the numerouscases in which the law of supply and demand left actualwants unsatisfied, so also many linguists are deaf tothose instances in which the very nature of a ianguagecalls forth misunderstandings in everyday conversation,(10)and in which, consequently, a word has to be modifiedor defined in order to present the idea intended by thespeaker: "He took his stick,no, not John's, but hisown." No language is perfec't, and if we admit this truth,we must also admit that it is not unreasonable to investi-(15)gate the relative merits of different languages or ofdifferent details in languages.24. The primary purpose ofthe passage is to(A) analyze an interesting feature of the English language(B) refute a belief held by some linguists(C) show that economic theory is relevant to linguistic study(D) iilustrate the confusion that can result from the improper use oflanguage(E) suggest a way in which languages can be made more nearly perfect.25. The misunderstanding presented by the author in lines 13-14 is similarto which of the following?I. X uses the word "you" to refer to a group, but Y thinks that X is referring to one person only.II. X mistakenly uses the word "anomaly" to refer to a typical example,.but Y knows that "anomaly" means "exception".III. X uses the word "bachelor" to mean "unmarried man:' but Y mistakenly thinks that bachelor means "unmarried woman."(A) I only(B) II only(C) III only(D) I and II only(E) IIand IIIonly26. In presenting the argument, theauthor does all of the following EXCEPT(A) give an example(B) draw a conclusion(C) make a generalization(D) make a comparison(E) present a paradox27. Which of the following contributes to the misunder- standing describedby the author in lines 13-14 ?(A) It is unclear whom the speaker of the sentence is addressing.(B) It is unclear to whom the word "his" refers the first time it is used.(C) It is unclear to whom the word "his" refers the second time it is used.(D) The meaning of "took" is ambiguous.(E) It is unclear to whom "He" refers.Directions: Each question below consists of a word printed in capital letters,followed by five lettered words or phrases.

GRE(QUANTITATIVE)综合模拟试卷1(题后含答案及解析)

GRE（QUANTITATIVE）综合模拟试卷1(题后含答案及解析) 题型有：1. 2. 3.1．正确答案：A解析：In this question you are asked to compare the price at which Emma sold the bicycle with $140. From the information given, you can conclude that Emma spent a total of 75 + 27 = 102 dollars buying and repairing the bicycle and that she sold it for 40 percent more than the $102 she spent buying and repairing it. If you notice that 140 is 40 percent more than 100, you can conclude that 40 percent more than 102 is greater than 40 percent more than 100, and therefore, Quantity A is greater than Quantity B. The correct answer is Choice A.(If you solve the problem in this way, you do not have to calculate the value of Quantity A.)Another way to solve the problem is by explicitly calculating the value of Quantity A and comparing the result with $140 directly. Since 40 percent of 102 is(0.4)(102)= 40.8, it follows that Quantity A, the price at which Emma sold the bicycle, is 102.00 + 40.80 = 142.80 dollars. Thus Quantity A, $142.80, is greater than Quantity B, $140, and the correct answer is Choice A.2．正确答案：C解析：In this question you are asked to compare the area of the shaded region with 36. You are given that both PQRV and VRST are squares with sides of length 6. Therefore, you can conclude that the length of QS is 12, and the area of the shaded right triangle PQS is 1/2(12)(6), or 36. Thus Quantity A is equal to Quantity B, and the correct answer is Choice C.3．正确答案：A解析：Before making the comparison in this problem, you need to analyze the information given to see what it tells you about the value of Quantity A, the property tax in 2009 on a home in Town X that had an assessed value of $160,000. One way of doing this is to determine the value of the constant p and then use that value to calculate the tax on the home that had an assessed value of $160,000. Since it is given that a home that had an assessed value of $125,000 had a property tax of $2,500,you can conclude that p is equal to[*], or 2%. Once you know that the property tax is 2% of the assessed value, you can determine that tax on the home that had an assessed value of $160,000 was 2% of 160,000, or 3,200. The correct answer is Choice A. Another way to calculate the property tax on a home with an assessed value of $160,000 is by setting up a proportion. Because the tax rate is the same for each home in Town X, you can let the variable x represent the tax for the home assessed at $160,000 and solve for x as follows.[*]The correct answer is Choice A.4．正确答案：D解析：One way to approach this question is to plug in values for one of the variables and determine the corresponding value for the other variable. One way to plug in: Plug in easy values. For example, you can plug in x = 0 and find that the corresponding value of y is -1; then you can plug in y = 0 and find that the corresponding value of x is -1. Since in the first case x is greater than y and in the second case y is greater than x, the correct answer is Choice D, the relationship cannot be determined from the information given. A second way to plug in: If you prefer to always plug in values of x to determine corresponding values of y, you can begin by writing the equation x +y = -1 asy = -x - 1. Writing it in this form makes it easier to find the corresponding values of y. You can start by plugging in the value x = 0. For this value of x, the corresponding value of y is y = -1, and therefore, x is greater than y. If you continue plugging in a variety of values of x, some negative and some positive, you will see that sometimes x is greater than y and sometimes y is greater than x. If you inspect the equation y = —x - 1, you can conclude that since there is a negative sign in front of the x but not in front of the y, for each value of x that is greater than 0, the corresponding value of y is less than 0; therefore, for each x > 0, x is greater than y. What about negative values of x? A quick inspection of the equation y = —x - 1 allows you to conclude that if x < -1, then y > 0, so y is greater than x. So for some values of x and y that satisfy the equation, x is greater than y; and for other values, y is greater than x. Therefore, the relationship between the two quantities x and y cannot be determined from the information given, and the correct answer is Choice D.5．正确答案：B解析：You are given that three numbers, r, s, and t, are consecutive odd integers and that rIn the last step of the simplification, you can easily see that 3 In the last step of the simplification, you can easily see that 1 In the figure above, what is the value of?A．2B．3C．4D．5E．6正确答案：C解析：The sum of the measures, in degrees, of the three interior angles of any triangle is 180°. As shown in the figure, the three angles of the triangle have measures of x°, y°, and z°, so x + y + z = 180. Therefore,= 4, and the correct answer is Choice C.8．A certain store sells two types of pens: one type for $2 per pen and the other type for $3 per pen. If a customer can spend up to $25 to buy pens at the store and there is no sales tax, what is the greatest number of pens the customer can buy?A．9B．10C．11D．12E．20正确答案：D解析：It is fairly clear that the greatest number of pens that can be bought for $25 will consist mostly, if not entirely, of $2 pens. In fact, it is reasonable to begin by looking at how many of the $2 pens the customer can buy if the customer does not buy any $3 pens. It is easy to see that the customer could buy 12 of the $2 pens, with $1 left over. If the customer bought 11 of the $2 pens, there would be $3 left over with which to buy a $3 pen. In this case, the customer could still buy 12 pens. If the customer bought 10 of the $2 pens, there would be $5 left over. Only 1 of the $3 pens could be bought with the $5, so in this case, the customer could buy only 11 pens. As the number of $2 pens decreases, the total number of pens that the customer can buy with $25 decreases as well. Thus the greatest number of pens the customer can buy with $25 is 12. The correct answer is Choice D.9．If y = 3x and z = 2y, what is x + y + z in terms of x ?A．10xB．9xC．8xD．6xE．5x正确答案：A解析：It is not necessary to find the individual values of x, y, and z to answer the question. You are asked to rewrite the expression x + y + z as an equivalent expression in terms of x. This means that you need to use the information provided about y and z to express them in terms of the variable x. The variable y is already given in terms of x; that is, y = 3x; and because z = 2y, it follows that z =(2)(3x)= 6x. Using substitution, you can rewrite the expression as follows.x + y + z=x +(3x)+(6x)=(1 +3 + 6)x =10xThe correct answer is Choice A.10．A certain shipping service charges an insurance fee of $0.75 when shipping any package with contents worth $25.00 or less and an insurance fee of $1.00 when shipping any package with contents worth over $25.00. If Dan uses the shipping company to ship three packages with contents worth $18.25, $25.00, and $127.50, respectively, what is the total insurance fee that the company charges Dan to ship the three packages?A．1.75B．2.25C．2.5D．2.75E．3正确答案：C解析：Note that two of the packages being shipped have contents that are worth $25.00 or less. Therefore, each of them has an insurance fee of $0.75, for a total of $1.50. The third package has contents worth over $25.00, and it has an insurance fee of $1.00. Therefore, the total insurance fee for the three packages is $1.50 + $1.00 = $2.50, and the correct answer is Choice C.11．If 55 percent of the people who purchase a certain product are female, what is the ratio of the number of females who purchase the product to the number of males who purchase the product?A．11 to 9B．10 to 9C．9 to 10D．9 to 11E．5 to 9正确答案：A解析：Note that because 55 percent of the people who purchase the product are females, it follows that 45 percent of the people who purchase the product are males. Therefore, the ratio of the number of females who purchase the product to the number of males who purchase the product is 55 to 45, or 11 to 9, and the correct answer is Choice A.12．In the rectangular solid above, TU = 3, UV = 4, and VR = What is the area of the shaded rectangular region?______正确答案：10解析：To find the area of the shaded rectangular region, you need to multiply the length of the rectangular region by its width. In this question you are given the lengths of three edges: TU = 3, UV = 4, and VR = 2. Note that VR is the length of the shaded rectangle. To find the width of the shaded rectangle, you need to find either RS or VT. Note that VT lies on the front face of the rectangular solid. It is the hypotenuse of right triangle VUT. You know that UV = 4 and TU = 3, so by the Pythagorean theorem you can conclude that VT == 5. Therefore, the area of the shaded rectangularregion is(5)(2)= 10. The correct answer is 10.13．A list of numbers has a mean of 8 and a standard deviation of 2.If x is a number in the list that is 2 standard deviations above the mean, what is the value of x ? x=______正确答案：13解析：You are given that x is 2 standard deviations above the mean, 8. Because the standard deviation of the numbers in the list is 2.5, it follows that x is(2)(2.5), or 5 units above the mean 8. Therefore, x = 8 + 5 = 13, and the correct answer is 13.14．The circle graph above shows the distribution of 200,000 physicians by specialty. Which of the following sectors of the circle graph represent more than 40,000 physicians?Indicate all such sectors.A．PediatricsB．Internal MedicineC．SurgeryD．AnesthesiologyE．Psychiatry正确答案：A,B,C解析：One approach to solve this problem is to find out what percent of 200,000 is 40,000 and then compare this percent with the percents given in the circle graph. Because= 0.2, it follows that 40,000 is 20% of 200,000, and any specialty that has more than 20% of the distribution has more than 40,000 physicians. This is true for the specialties of pediatrics, internal medicine, and surgery. The correct answer consists of Choices A, B, and C.。

D.authoritative G.An originalityB.realistic E.animated H.An impulsivenessC.unesteemed F.trendy I.A stalenessIn1755British writer Samuel Johnson published an acerbic letter to Lord Chesterfield rebuffing his patron for neglecting and declining further support.Johnson’s rejection of his patron’s belated assistance has often been identified as a key moment in the history of publishing,marking the end of the culture of patronage.However,patronage had been in decline for50years,yet would survive,in attenuated form,for another50.Indeed,Johnson was in1762awarded a pension by the Crown–a subtle form of sponsorship,tantamount to state patronage.The importance of Johnson’s letter is not so much historical as emotional;it would become a touchstone for all who repudiated patrons and for all who embraced the laws of the marketplace.7.The author of the passage mentions Johnson’s1762pension award in order toA.reveal that Johnson remained consistent in his rebuke of Lord Chesterfield well after1755B.provide evidence for a general trend in the later half of the eighteenth century of privatepatronage’s being replaced by state sponsorshipC.situated the debate over the end of patronage within the wider realm of eighteenth-centuryeconomic historyD.suggest that Johnson’s letter to Chesterfield was noticed by the crown only years after it waspublishedE.emphasize that patronage still helped support Johnson’s writing after his letter to Chesterfield8.Which of the following best describes the function of the highlighted sentence in the context ofthe passage as a whole?A.It points out the most obvious implications of Johnson’s letter to his patronB.It suggests a motivation for Johnson’s rejection of Chesterfield’s patronageC.It provides information that qualifies the assertion that Johnson’s letter sharply defined the endof a publishing eraD.It provides a possible defense for Chesterfield’s alleged neglect of JohnsonE.It refutes the notion that patrons are found primarily among the nobility“Blues is for singing,”writes folk musicologist Paul Oliver,and“is not a form of folk song that stan…(?)particularly well when written down.”A poet who wants to write blues can attempt to avoid this problem poeticizing the form–but literary blues tend to read like bad poetry rather than like refined folk song.For Oliver,the true spirit of the blues inevitably eludes the self-conscious imitator.However,Langston Hughes,the first writer to grapple with these difficulties of blue poetry in fact succeeded in producing poems that capture the quality of genuine,performed blues while remaining effective as poems.In inventing blues poetry,Hughes solved two problems:first,how to write blues lyrics in such a way that they work on the printed page,and second,how to exploit the blues form poetically without losing all sense of authenticity.There are many styles of blues,but the distinction of importance to Hughes is between the genres referred to as“folk blues”and“classic blues.”Folk blues and classic blues are distinguishedfrom one another by differences in performers(local talents versus touring professionals), patronage(local community versus mass audience),creation(improvised versus composed),and transmission(oral versus written).It has been a commonplace among critics that Hughes adopted the classic blues as the primary model for his blues poetry,and that he writes his best blues poetry when he tries least to imitate the folk blues.In this view,Hughes’attempts to imitate the folk blues are too self-conscious,too determined to romanticize the African American experience,too intent on reproducing what he takes to be the quaint humor and naïve simplicity of the folk blues to be successful.But a more realistic view is that by conveying his perceptions as a folk artist ought to–through an accumulation of details over the span of his blues oeuvre,rather than by overloading each poem with quaintness and naivety–Hughes made his most important contributions to the genre.His blues poems are in fact closer stylistically to the folk blues on which he modeled them than to the cultivated classic blues.Arnold Rampersad has observed that virtually all of the poems in the1927collection in which Hughes essentially originated blues poetry fall deliberatively within the“range of utterance of common folk.This surely applies to“Y oung Gal’s Blues,”in which Hughes avoids the conventionally“poetic”language and images that the subjects of death and love sometimes elicit in his ordinary lyric poetry.T o see what Hughes’blues poetry might have been like if he had truly adopted the classic blues as his model,one need only look to“Golden Brown Blues,”a song lyric Hughes wrote for composer W.C.Handy.Its images,allusions,and diction are conspicuously remote from the common“range of utterance.”9.The primary purpose of the passage is toA.describe the influence of folk and classic blues on blues poetryB.analyze the effect of African American culture on Blues poetryC.demonstrate that the language used in Hughes’blues poetry is colloquialD.defend Hughes’blues poetry against criticism that it is derivativeE.refute an accepted view of Hughes’blues poetry style10.The author of the passage uses the highlighted quotation primarily toA.indicate how blues poetry should be performedB.highlighted the difficulties faced by writers of blues poetryC.support the idea that blues poetry is a genre doomed to failD.illustrate the obstacles that blues poetry is unable to overcomeE.suggest that written forms of blues are less authentic than sung blues]11.It can be inferred from the passage that,as compared with the language of“Golden BrownBlues,”the language of“Y oung Gal’s Blues”isA.more colloquialB.more melodiousC.marked by more allusionsD.characterized by more conventional imageryE.more typical of classic blues song lyrics12.According to the passage,Hughes’blues poetry and classic blues are similar in which of thefollowing ways?A.Both are improvisedB.Both are written downC.Both are intended for the same audienceD.Neither uses colloquial languageE.Neither is professionally performed13.Far from innovations,as

designing experiments to be conducted during space flights has been made available by the government space program to university biologists not already employed by the space program.From the fact that little interest has been expressed in this offer,however,it cannot be concluded that virtually the only biologists interested in research that such experiments could address are those biologists already employed by the space program,since17.Which of the following most logically complete the passage?A.relatively few of the biologists already employed by the space program have ever helduniversity positions.B.there are more research biologist in industry than at universities.C.biologists are not the only scientists interested in research that could be furthered by theopportunity to conduct experiments in space.D.the space program employs only a small percentage of the research biologists employed by thegovernment.E.Much of the biological research currently funded by the government’s space program isconcerned with the biological effects of a weightless environment.The recent announced discovery of the first known planet orbiting a pulsar(the ultradense, pulsating remnant off the supernova explosion of a star)turned out to be based on faulty data.Had this discovery been confirmed,theorists would have had difficulty accounting for the existence of such a planet.The supernova would certainly have destroyed any preexisting planets.This particular pulsar is relatively young,allowing little time for a new planet to have coalesced,and it rotates relatively slowly,implying that it has not interacted with any nearby star since the supernova.But newer evidence of a different pulsar with planets is more promising.This is a rapidly spurring“millisecond pulsar”thought to be a much older object that has pulled gaseous material from a stellar neighbor,causing its rotational speed to increase.Leftover,unconsumed gas around such a pulsar could,in theory,coalesce into planets.Or the pulsar’s radiation might have vaporized a companion star,providing new material for planetary formation.18.The primary purpose of the passage is toA.provide an example of the dangers of a recent discovery based on faulty dataB.illustrate the difficulty of explanation concerning a recent discoveryC.assess the credibility of recent findings concerning the as yet unverified existence of a class ofobjectsD.argue that a certain hypothesis fails to account for a seemingly contradictory phenomenonE.demonstrate how difficult it might be to find out the reality of a phenomenon19.Which of the following can be inferred regarding the pulsar discussed in the first paragraph?A.Theorists initially doubted its existence.B.If its existence had been confirmed,astronomers would and have turned their attention to thepulsar discussed in the second paragraph.C.If the supernovas explosions that created it had been more powerful,the resulting radiationwould have preceded the subsequent formation of a planet.D.If it had interacted with a nearby star since the supernova explosion,it would rotate faster thanit does.E.Astronomers’interest in it ultimately led to a new theory of planetary formation.20.(?)Section21.Barring the discovery of new letters,hidden diaries,or the like,fresh information abouteminent people is hard to find because their lives have been so intensely.A.ridiculedB.scrutinizedC.admiredD.embellishedE.underrated2.Despite having only recently learned to walk,toddlers make the most dance students.Their joy in movement

outright destroyed,by the wind.There were few,however,so the form.A.a propitious D.obvious parallels G.declinedB.a conspicuous E.practical alternative H.inspiredC.an equivocal F.unnoticed instances I.persisted5.The experimental theater company’s members know that their performances anaudience,that they were dense and unpredictable and not always easy to digest.But none of the techniques used would be anyone with an interest in music or films.Indeed,they would seem strange only to people who expected to see traditionally crafted plays.The actors therefore felt that theater critics’derisive

characters in this comic strip fret about the of their“little counterculture lives,”especially when terrible things are happening in the world,but the cartoonist makes their lives in ways that do not seem at all.Real things happen here–birth,deaths,adoptions, affairs,breakups,commitments,ceremonies,civil union–and they matter.A.unpredictability D.stagnate G.outlandishB.arduousness E.resonate H.inconsequentialC.triviality pete I.intangibleDuring the Pleistocene epoch,several species of elephants isolated on islands underwent rapid dwarfing.This phenomenon was not necessarily confined to the Pleistocene,but may have occurred much earlier in the southeastern Asian islands,although evidence is fragmentary.Several explanations are possible for this dwarfing.For example,islands often have not been colonized by large predators or are too small to hold viable predator populations.Once free from predation pressure,large body size is of little advantage to herbivores.Additionally,island habitats have limited food resources,a smaller body size and a need for fewer resources would thus be favored. Interestingly,the island rule is reversed for small mammals such as rodents,for which gigantism is favored under insular conditions.7.The primary purpose of the passage is toA.question the plausibility of one explanation sometimes offered for the dwarfing of certainspecies living on islands.B.argue that dwarfing of certain species living on islands occurred prior to the Pleistocene.C.cite evidence suggesting that dwarfing may have adverse consequences for some species livingon islands.D.present some possible explanations for the dwarfing of certain species living on islands.E.contrast the effect of insular conditions on species with large body size and species with smallbody.8.According to the passage,which of the following statements about body size in mammals istrue?A.A large body is unfavorable to mammalian species’survival under most conditions.B.A large body tens to benefit small mammals living on islands.C.For most herbivorous mammals,a large body size is easier to sustain in the absence of largepredators.D.Under most conditions,a small body is less beneficial to herbivorous mammals than tonon-herbivorous mammals.E.Among non-herbivorous mammals,a small body is more beneficial on an island than on amainland.The“deindustrialization”thesis of Bluestone and Harrison asserts that the replacement of domestic with foreign manufacturing begun by United States corporations in the late1960s resulted in a“hollowing out”of American industry,whereby workers displaced from manufacturing jobs through massive plant closings found themselves moving more or less permanently into lower-paying,less secure jobs or into unemployment.Critics of the deindustrialization thesis have argued that new service and high-technology sectors of the United states economy have recently created a substantial number of jobs.While these critics do not deny the painful aspects of this transition from an industrial to a service-and information-based economy,they argue that it will be short-term,and a necessary evil if the United States is to have a long-term increase in living standards.Critics of the emerging economy,however point to disturbing evidence of an “hourglass”effect:a shrinking middle tier of managerial and blue-collar unionized workers and consequent polarization of incomes.The emergence of a technical and financial elite,they argue, has brought forth a host of low-wage jobs to service the new economy,and it is this service sector that many ex-industrial workers must seek.9.The purpose of the passage is toA.analyze the events that contributed to an economic phenomenonB.present different views on the nature and impact of an economic phenomenonC.distinguish between the short-term and long-term effects of an economic phenomenonD.challenge a dominant theory about how to solve the problems created by an economicphenomenonE.present new evidence to suggest that an economic phenomenon is more complex than hadpreviously been believed10.Which of the following,if true,would most tend to weaken the deindustrialization thesis ofBluestone and Harrison?A.A survey of the spouses of former industrial workers reveals a significant increase in thenumber of working spouses since the mid-1960s.B.Data from the most recent United States census show that fewer individuals list theiroccupation as industrial worker than in the census from ten years earlier.C.A random survey of United States consumers indicates that a majority of those surveyed wouldprefer to buy united states-manufacturing goods if given the opportunity.D.A recent study indicates that large numbers of former industrial workers have retrained andfound employment as skilled,highly-paid computer workers.E.Interviews with representatives at major agencies for temporary employment in the UnitedStates suggest that they value the skills of the former industrial workers.11.It can be inferred from the passage that the highlighted“critics”believe which of the followingabout“hourglass”effect?A.It involves the relegation of industrial workers to less desirable jobs.B.It requires that workers make short-term sacrifices to achieve long-term gains.C.It affects non-unionized workers more strongly than it does unionized workers.D.It represents an increase in unemployment for those in the service sector.E.It threatens the status of the technological and financial elite.12.One is that so far,web services have turned out to be much harder to deliver thantheir champions had hoped.A.hopeB.snagC.prospectD.hitchE.upshotF.reason13.Asserting a need to preserve the that became the hallmark of her predecessor’s tenure,the new director of federal monetary policy refused to subscribe to rigid or mechanistic rules in policy making.A.firmnessB.adaptabilityC.unpredictabilityD.autonomyE.strictnessF.flexibility14.Wilson is wont to emphasize the of ants,how ants with full stomachs willregurgitate liquid food for those without,or how the old will fight so the young can survive.A.beneficenceB.altruismC.unpredictabilityD.intelligenceE.fecundityF.fertility15.At first,most of the famous fairy tales seem so implausible and so irrelevant to contemporarylife that their is hard to understand.A.universalityB.persistenceC.appealD.ephemeralityE.survivalF.transiencePrincessfish are a species of coral-reef fish that are captured alive by divers who first stun the individual fish by squirting a certain poison at them.Since the divers limit their catch to a few individuals and take care not to overfish,the divers’continuing activities will clearly not result in serious harm to populations of princessfish.16.Which of the following,if true,most seriously weaken the argument given?A.Princessfish cannot be captured alive by traditional methods of fishing.B.The poison used to stun the princessfish has no effect on humans who eat them.C.Demand for princessfish has remained steady during the last decade.D.T races of the poison that remain in the seawater damage the Corals that create and maintain thereefs on which princessfish depend.E.Fish that have been stunned but have selected for capture by the divers soon recover from thetemporary effect of the poison.Was resource intensification–an increase in labor and time devoted to subsistence activities in order to increase food yields–by Dorset Paleo-Eskimos and Recent Indians on the island of Newfoundland simply a response to population pressure?Not exactly.On Newfoundland, population pressure did not result from a steadily growing resident population but,rather,from the arrival and lingering presence of new and significantly different populations.Newfoundland’s hunter-gatherer populations–both resident and newcomer–adjusted to the presence of other populations through niche differentiation.Building on a tradition that emphasized marine resources, Dorset Paleo-Eskimos intensified their harvest of seals in response to the arrival of Recent Indians in the first few centuries A.D.Recent Indians who were more familiar with broad-based, interior-maritime adaptation,intensified this strategy to cope with the Dorset.17.According to the passage,which of the following resulted from the arrival of the recentIndians?A.The Dorset Paleo-Eskimos were forced to compete with the Recent Indians for a limited supplyof seals.B.The Dorset Paleo-Eskimos spent more time harvesting seals than they had in the past.C.The Dorset Paleo-Eskimos increased the amount of labor and time devoted to defending theirterritory.D.The Dorset Paleo-Eskimos began to adopt new subsistence strategies they learned from theRecent Indians.E.The previously steady growth of the Dorset Paleo-Eskimos population came to a halt.18.Which of the following best describes the function of the highlighted sentence in the context ofthe passage as a whole?A.It points out a flaw in a theory discussed earlier in the passage.B.It demonstrates the need for additional research on a phenomenon mentioned earlier in thepassage.C.It underscores the importance of a trait mentioned earlier in the passage.D.it supports an assertion made earlier in the passage.E.It questions the evidence for a tradition mentioned earlier in the passage.Founder mutations are a class of disease-causing genetic mutations,each derived from its own ancestral“founder”in whom the mutation originated,While most disease-causing mutated are found in humans at a rate of one in a few thousand to one in a few million people,founder mutation can occur at much higher rates,This apparent anomaly is partially explained by the fact that most founder mutations are recessive:only a person with copies of the affected gene from both parentsbecomes ill.Most people with only one copy of the gene—“carriers”—survive and pass the gene to offspring.Furthermore,the single copy of a founder mutation often confers a survival advantage on carriers.For example,the hereditary hemochromatosis mutation protects carriers from iron-deficiency anemia because the mutated gene allows increased efficiency of iron absorption.19.The passage indicates which of the following about founder mutations?A.Carriers of founder mutation may receive certain benefits from the mutated gene.B.People who inherit founder mutations from both parents can become ill as a result.C.Founder mutations are less likely than other mutations to be passed to offspring.20.The author of the passage mentions the hereditary hemochromatosis mutation”primarily inorder to illustrate(?)A.the circumstances under which a founder mutation fails to cause a diseaseB.how difficult it is to predict the effects of founder mutations on carriersC.the difference between harmful founder mutation and those that are beneficialD.how a single copy of a founder mutation can benefit a carrierE.a challenge to a particular about the transmission of founder mutations。
