GRE 美国研究生入学考试部分题解析

1、As people rely more and more on technology to solve problems, the ability of humans to think for themselves will surely deteriorate.People’s live is full of technology products which bring us much convenience. Vehicles such as autos as well as aircrafts increase humanity’s efficiency of trips or journeys so that everyone has more leisure time. Besides, calculators and computers to which almost every people belongs make us to calculate more rapidly and accurately. Virtually, all technology products demonstrate that it develops social progress.In spite of many advantages of technology, it cause a number of problems. There is no doubt that people go up to higher floor via electric elevator instead of climbing steps, have a trip by auto vehicles instead walking and also writing in PC not in paper by pen. Admittedly technology induce us to become more and more lazy result in our ideas which become simple and thinking ability which become narrow.2、. I disagree with a national curriculum because all students are not the same, they have different interests, and this curriculum would not permit teachers to explore and teach to students interests.First, a curriculum that becomes nation wide is supposed to teach all students the same material and perhaps the same way. All seventh graders will have to solve algebraic equations and then they will all be the same. But students are not the same. All children develop at different rates, they have different abilities. One cannot expect a child from Uptown Manhattan to be doing the same thing as the kids in southern Illinois. The conditions are different, they have different funding and quality of teachers. Parents involvement in their childrens education is different and that would affect what the students learn.Besides having different abilities, the students have different interests or necesities. In one part of the nation it may be important to learn trigonometry and calculus because it is a high tech area. They use many computers and there might be a big market for careers in that field, but in another part of the country it might be more important to learn about farming and erosion. That the interest would be different. Teachers also need the freedom to teach what the students are interested in. If the kids want to know about the Chicano Movement, they should have the opportunity to learn about it, instead of learning about African American Civil Rights Movement. City kids are interested in different things than kids rural areas, as well as kids from the East Coast and the West Coast.For these reasons I would have to disagree with a national curriculum. Children are different and they should have the right to learn about things they are interested in. Teachers should have the freedom to teach what he/she thinks is more important or interesting to their students. Teachers should teach their students, not a curriculum.3、I am favor of the opinion that formal education is a part of education, it is ok when it set our mind free, If not, no matter whether formal education restrain our minds, We have more remedy for it. The reasons as follows: It is commonly accepted that the purpose of formal education is develop reasoning, master the methods of scientific inquiry, cultivate the intellect .In this extent, formal education give students basic knowledge and common-sense that we tend to discover the world and resolve the problem with it. There is no sigh to indicate formal education provided by any school or college tend to restrictive someone on doing something. That is to say, teacher in the school taught us basic knowledge , the methods of learning, We decided which one to learned or how we will be. Additionally, formal education can give student more chance to learn all kinds of things and try more. For example state-run school has funding aid from government, which make the school have more resources, new lab, new library, latest books and periodical, and so on. Formal education and home education is often at odds, sometime, home education can’t provide costing instruments to student. Without these instruments may hinder someone ‘s invention.Moverever, If the formal education in some school, is trotted with the score restraining our mind to pursuing high score.5、Teachers'salaries should be based on the academic performance of their students.Disagree:Students’academic performance is mostly dependent on their own efforts and intellectual perception in the subjects.Teachers only play a small part in their achievement.Moreover,it is also possible for some additional educational unbalance to take place,such as teachers would reject to teach in remote areas.Indeed,it can help teachers to gain their interests in teaching in a way.Students must the Core of a school but you can not require all the tutors to concentrate only on the perform ance of the teaching.though it can ensure that the teacher will emphasize the teachingReduce the importance of intellectual reaserch remote area Will cause unbalance in educationresource to take place.all the time on6、The first is essentially the Darwinian argument that extinction results from the inexorable process of so-called "natural selection" in which stronger species survive whileweaker ones do not.然而，professional agency of species protection公布的数据表明，目前动物因为人类灭绝的数量是自然灭绝的100 倍。

(10)if committed by adults, these actions are not even considered prosecutable; if committed by juvenile males, they have traditionally been looked on leniently by the courts. thus ironically, the plight of female delinquents receives (15)little scrutiny because they are accused of committing relatively minor offenses. second, the courts have long unjustified so-called preventive intervention into the lives of young females viewed as antisocial with the rationale that(20)women are especially vulnerable. traditional stereotypes of women as the weaker and more dependent sex have led to earlier intervention and longer periods of misdirected supervision for female delinquents than for males.17. which of the following statements best expresses the irony pointed out by the authors in lines 13-16 of the passage?(a) female delinquents tend to commit victimless crimes more frequently than their male counterparts.(b) the predicament of male delinquents receives more attention than that of females because males are accused of more serious crimes.(c) adults are frequently punished less severely than adolescents for committing more serious crimes.(d) the juvenile justice system cannot correct its biases because it does not even recognize them.(e) although the number of female delinquents is steadily increasing, the crimes of which they are accused are not particularly serious.18. it can be inferred from the passage that the authors believe traditional stereotypes of women to be(a) frequently challenged(b) persistently inexplicable(c) potentially harmful(d) rapidly changing(e) habitually disregarded19. the passage suggests that scholars in criminal justice could be criticized for which of the following?(a) underestimating the seriousness of juvenile crime(b) rationalizing the distinction made between juveniles and adults in the legal system(c) concerning themselves too little with the prevention of juvenile delinquency(d) focusing on those whose crimes have involved damage to persons or property(e) failing to point out injustices in the correctional systemscattered around the globe are more than one hundred regions of volcanic activity known as hot spots. unlike most volcanoes, hot spots are rarely found along the boundaries of the continental and oceanic plates that comprise the earth's crust; most hot spots lie deep in the interior of plates and are anchored deep in the layers of the earth's surface. hot spots are also distinguished from other volcanoes by their lavas, which contain greater amounts of alkali metals than do thosefrom volcanoes at plate margins.in some cases, plates moving past hot spots have left trails of extinct volcanoes in much the same way that wind passing over a chimney carries off puffs of smoke. it appears that the hawaiian islands were created in such a manner by a single source of lava, welling up from a hot spot, over which the pacific ocean plate passed on a course roughly from the east toward the northwest, carrying off a line of volcanoes of increasing age. two other pacific island chains- the austral ridge and the tuamotu ridge-parallel the configuration of the hawaiian chain; they are also aligned from the east toward the northwest, with the most recent volcanic activity near their eastern terminuses.that the pacific plate and the other plates are moving is now beyond dispute; the relative motion of the plates has been reconstructed in detail. however, the relative motion of the plates with respect to the earth's interior cannot be determined easily. hot spots provide the measuring instruments for resolving the question of whether two continental plates are moving in opposite directions or whether one is stationary and the other is drifting away from it. the most compelling evidence that a continental plat isstationary is that, at some hot spots, lavas of several ages are superposed instead of being spread out in chronological sequence. of course, reconstruction of plate motion from the tracks of hot-spot volcanoes assumes that hot spots are immobile, or nearly so. several studies support such an assumption, including one that has shown that prominent hot spots through- out the world seem not to have moved during the past ten million years.beyond acting as frames of reference, hot spots apparently influence the geophysical processes that propel the plates across the globe. when a continental plate comes to rest over a hot spot, material welling up from deeper layers forms a broad dome that, as it grows, develops deep fissures. in some instances, the continental plate may rupture entirely along some of the fissures so that hot spot initiates the formation of a new ocean. thus, just as earlier theories have explained the mobility of the continental plates, so hot-spot activity may suggest a theory to explain their mutability.20. the primary purpose of the passage is to(a) describe the way in which hot spots influence the extinction of volcanoes(b) describe and explain the formation of the oceans andcontinents(c) explain how to estimate the age of lava flows from extinct volcanoes(d) describe hot spots and explain how they appear to influence and record the motion of plates(e) describe the formation and orientation of island chains in the pacific ocean21. according to the passage, hot spots differ from most volcanoes in that hot spots(a) can only be found near islands(b) are active whereas all other volcanoes are extinct(c) are situated closer to the earth's surface(d) can be found along the edges of the plates(e) have greater amounts of alkali metals in their lavas22. it can be inferred from the passage that evidence for the apparent course of the pacific plate has been provided by the(a) contours of the continents.(b) dimensions of ocean hot spots(c) concurrent movement of two hot spots(d) pattern of fissures in the ocean floor(e) configurations of several mid-ocean island chains23. it can be inferred from the passage that the spreading out of lavas of different ages at hot spots indicates that a(a) hot spot is active(b) continental plate has moved(c) continental rupture is imminent(d) hot spot had been moving very rapidly(e) volcano contains large concentrations of alkali metals24. the passage suggests which of the following about the hawaiian islands, the austral ridge, and the tuamotu ridge?(a) the three chains of islands are moving east- ward.(b) all the islands in the three chains have stopped moving.(c) the three islands chains are a result of the same plate movement.(d) the hawaiian islands are receding from the other two island chains at a relatively rapid rate.(e) the austral ridge and the tuamotu ridge chains have moved closer together whereas the hawaiian islands have remained stationary.25. which of the following, if true, would best support the author's statement that hot-spot activity may explain the mutability of continental plates?(a) hot spots move more rapidly than the continental and oceanic plates.(b) hot spots are reliable indicators of the age of continental plates.(c) hot spots are regions of volcanic activity found only in the interiors of the continental plates.(d) the alignment of hot spots in the pacific. ocean parallels the alignment of pacific ocean islands.(e) the coastlines of africa and south america suggest that they may once have constituted a single continent that ruptured along a line of hot spots.26. the author's argument that hot spots can be used to reconstruct the movement of continental plates is weakened by the fact that(a) hot spots are never found at the boundaries of plates(b) only extinct volcanoes remain after a plate moves over a hot spot(c) lava flow patterns for all hot spots have not been shown to be the same(d) the immobility or near immobility of hot spots has not been conclusively proven(e) the changing configurations of islands makepinpointing the locations of hot spots difficult27. the author's

However, since this new form of the fungus can be killed by increased application of currently used fungicides, it is unlikely that the fungus will cause widespread food shortages in countries that currently rely on potatoes for sustenance.Which of the following, if true, most calls into question the con- clusion in the argument above?SSS_SINGLE_SELAThough potatoes are an important staple crop in many parts of the world, people in most countries rely primarily on wheat or rice for sustenanceBPotato farmers in many countries to which the new form of the fungus has spread cannot afford to increase their spending on fungicidesCThe new form of the fungus first began to spread when contaminated potato seeds were inadvertently exported from a major potato-exporting country.Potato farmers in most countries use several insecticides on their crops in addition to fungicides of the sort that kill the new form of the fungus.EMost governments have funds set aside that can be used to alleviate the effects of large-scale disasters such as severe food shortages and floodsThere are eight questions below，The organizers of a music festival are scheduling exactly six master classes, one class per day for six consecutive days. Three of the classes will be given by violinists and three by pianists. The only musicians who can teach the classes are the violinists F, G, H, and J, and the pianists R, S, T, W, and Z.

At the same time their tissues stiffen. For example, the lungs and the heart muscle expand less successfully, the blood vessels become increasingly rigid, and the ligaments and tendons tighten .Few investigators would attribute such diverse effects to a single cause. Nevertheless, researchers have discov- ered that a process long known to discolor and toughen foods may also contribute to age- related impairment of both cells and tissues. That process is nonenzymatic glycosylation, whereby glucose becomes attached to proteins without the aid of enzymes. When enzymes attach glucose to proteins (enzymatic glycosylation), they do so at a specific site on a specific protein molecule for a specific purpose. In contrast, the nonenzymatic process adds glucose haphazardly to any of several sites along any available peptide chain within a protein molecule.This nonenzymatic glycosylation )has been understood by food chemists for decades, although few biologists recognized until recently that the same steps could take place in the body. Nonenzymatic glycosylation begins when an aldehyde group (CHO) of glucose and an amino group (NH2) of a protein are attracted to each other. The **bine, forming what is called a Schiff base within the protein. **- bination is unstable and quickly rearranges itself into a stabler, but still reversible, substance known as an Amadori product.If a given protein persists in the body for months or years, some of its Amadori products slowly dehydrate and rearrange themselves yet again, into new glucose-derived structures. These **bine with various kinds of mol- ecules to form irreversible structures namedadvanced glycosylation end products (AGE's). Most AGE's are yellowish brown and fluorescent and have specific spectrographic properties. More important for the body, many are also able to cross-link adjacent proteins, particularly ones that give structure to tissues and organs. Although no one has yet satisfactorily described the origin of all such bridges between proteins, many investigators agree that extensive cross-linking of proteins probably contrib- utes to the stiffening and loss of elasticity characteristic of aging tissues.In an attempt to link this process with the develop- ment of cataracts (the browning and clouding of the lens of the eye as people age), researchers studied the effect of glucose on solutions of purified crystallin, the major protein in the lens of the eye. Glucose-free solutions remained clear, but solutions with glucose caused the proteins to form clusters, suggesting that the molecules had become cross-linked. The clusters diffracted light, making the solution opaque. The researchers also discovered that the pigmented cross-links in human cataracts have the brownish color and fluorescence characteristic of AGE's. These data suggest that nonenzymatic glycosylation of lens crystallins may contributeto cataract formation.SSS_SINGLE_SELWith which of the following statements concerning the stiffening of aging tissues would the author most likely agree?AIt is caused to a large degree by an increased rate of cell multiplication.BIt paradoxically both helps and hinders the longevity of proteins in the human bodyCIt can be counteracted in part by increased ingestion of glucose-free foods.DIt is exacerbated by increased enzymatic glycosylation.EIt probably involves the nonenzymatic glycosylation of proteins.SSS_SINGLE_SELAccording to the passage, which of the following statements is true of the process that discolors and toughens foods?AIt takes place more slowly than glycosylation in the human bodyBIt requires a higher ratio of glucose to protein than glycosylation requires in the human body.CIt does not require the aid of enzymes to attach glucose to protein.DIt proceeds more quickly when the food proteins have a molecular structure similar to that of crystallin proteins.EIts effectiveness depends heavily on the amount of environmental moistureSSS_SINGLE_SELAccording to the passage, which of the following is characteristic of enzymatic glycosylation of proteins?AAGE's are formed after a period of months or years.BProteins affected by the process are made unstable.CGlucose attachment impairs and stiffens tissues.DGlucose is attached to proteins for specific purposes.EAmino **bine with aldehyde groups to form Schiff bases.SSS_SINGLE_SELAccording to the passage, which of the following statements is true of Amadori products in proteins?AThey are more plentiful in a dehydrated environment.BThey are created through enzymatic glycosylation.CThey **posed entirely of glucose molecules.DThey are derived from Schiff bases.EThey are derived from AGE's.SSS_SINGLE_SELWhich of the following best describes the function of the third paragraph of the passage (lines 19-29)?AIt offers evidence that contradicts the findings described in thefirst two paragraphsBIt presents a specific example of the process discussed in the first two paragraphsCIt explains a problem that the researchers mentioned in the second paragraph have yet to solve.DIt evaluates the research discoveries described in the previous paragraph.EIt begins a detailed description of the process introduced in the previous two paragraphs.SSS_SINGLE_SELThe passage suggests that which of the following would be LEAST important in determining whether nonenzymatic glycosylation is likely to have taken place in the proteins of a particular tissue?AThe likelihood that the tissue has been exposed to free glucoseBThe color and spectrographic properties of structures within the tissueCThe amount of time that the proteins in the tissue have persisted in the bodyDThe number of amino groups within the proteins in the tissueEThe degree of elasticity that the tissue exhibitsSSS_SINGLE_SELIf the hypothesis stated in lines 56-58 is true, it can be inferred that the crystallin proteins in the lenses of peopleAhave increased elasticityB。

However, since this new form of the fungus can be killed by increased application ofcurrently used fungicides, it is unlikely that the fungus will cause widespread food shortages in countries thatcurrently rely on potatoes for sustenance. Which of the following, if true, most calls into question the con- clusion in the argument above? (A)Though potatoes are an important staple crop in many parts of the world, people in most countries rely primarily on wheat or rice for sustenance. (B)Potato farmers in many countries to which the new form of the fungus has spread cannot afford to increase their spending on fungicides. (C)The new form of the fungus first began to spread when con- taminated potato seeds were inadvertently exported from a major potato-exporting country. (D)Potato farmers in most countries use several insecticides on their crops in addition to fungicides of the sort that kill the new form of the fungus. (E) Most governments have funds set aside that can be used to alleviate the effects of large-scale disasters such as severe food shortages and floods.

In a small office suite, six offices are arranged in a straight line, one after another, and are consecutively num- bered1 through6. Exactly six people― P, Q, R, S, T and U― are to be assigned to these six offices, exactly one person to an office, according to the following conditions: P must be assigned to an office immediately adjacent to the office to which T is assigned. Q cannot be assigned to an office immediately adja- cent to the office to which S is assigned. R must be assigned either to office1 or to office6. S must be assigned to a lower-numbered office than the office to which U is assigned.17.Which of the following can be the list of the six people in the order of their offices, from office1 through office6?

This shift means that research projects likely to produce controversial results will almost certainly prise a smaller proportion of all funded research projects, since private foundations, concerned about their public image, tend to avoid controversy. Which of the following is an assumption on which the argument depends? (A)Only research that is conducted without concern for the possibility of generating controversy is likely to produce scientifically valid results. (B)Private foundations that fund scientific research projects usually recognize that controversial results from those projects cannot always be avoided. (C) Scientists who conduct research projects funded by private foundations are unlikely to allow the concerns of the funding organizations to influ- ence the manner in which they conduct the research. (D)Many government agencies are more concerned about their public image than are most private foundations. (E) Government agencies are more willing than are private foundations to fund research projects that are likely to produce controversial results.24.Juries in criminal trials do not base verdicts on uncor- roborated testimony given by any one witness. Rightly so, because it is usually prudent to be highly skeptical of unsubstantiated claims made by any one person. But then, to be consistent, juries should end an all- too-mon practice: convicting defendants on the basis of an uncorroborated full confession. Which of the following, if true, most strengthens the argument above?(A)Juries often acquit in cases in which a defendant retracts a full confession made before trial. (B) The process of jury selection is designed to screen out people who have a firm opinion about the defendant s guilt in advance of the trial. (C)Defendants sometimes make full confessions when they did in fact do what they are accused of doing and have e to believe that the prose- cutor has pelling proof of this. (D)Highly suggestible people who are accused of wrongdoing sometimes bee so unsure of their own recollection of the past that they can e to accept the accusations made against them. (E)Many people believe that juries should not con- vict defendants who have not made a full con- fession.25.Although spinach is rich in calcium, it also contains large amounts of oxalic acid, a substance that greatly impedes calcium absorption by the body. Therefore, other calcium-containing foods must be eaten eitherinstead of or in addition to spinach if a person is to be sure of getting enough calcium. Which of the following,if true, most seriously weakens the argu-ment above?(A)Rice, which does not contain calcium, counteracts the effects of oxalic acid on calcium absorption. (B) Dairy products, which contain even more calcium than spinach does, are often eaten by people who eat spinachon a regularbasis. (C)Neither the calcium nor the oxalic acid in spinach is destroyed when spinach is cooked. (D)Many leafy green vegetables other than spinach thatare rich in calcium also contain high concentrations of oxalic acid. (E)Oxalic acid has little effect on the body s abilityto absorb nutrients other than calcium.SECTION2 Time –30 minutes30 Questions1.x – y –3 = 02.xy。

Moreover， the incidence of solar flares and the flux of solar cosmic rays，ultraviolet radiation， 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 collectively 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 variables 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。
