gre阅读如何判断是否为干扰项

gre考试阅读干扰选项之歪曲事实。

比如一篇文章的本意明明是作者在客观描述一个现象或者阐述一种概念或理论，歪曲选项却会变成作者在争论一个观点或者支持某种说法。歪曲文章本意是指在阅读题中，会出现一种使用了文章部分内容，却推导出于文章本意相反结论的选项。鉴别歪曲选项要求考生在读文章时能够准确抓住主旨，如此就不会受到迷惑了。

gre考试阅读干扰选项之极端语言。

gre备考攻略提示，gre的阅读文章通常都是客观和全面的。即使文章中在争论某个观点或者想法，作者通常也会综合两方意见进行一些相对平衡的讨论方式。而Always,any, all, never,none。这些词汇往往代表着一个错误的选项。所以如果阅读题的选项中出现了一些使用了极端词汇或者绝对观点的内容，那么这个说法毫无疑问的是错误选项。

gre考试阅读干扰选项之无中生有。

阅读题的解答始终都应该围绕文章本体进行，没有在文章中提到的内容即使看似再正确，也只能是错误选项。在做阅读题时，考生应时刻注意那些包含文章未提及的新内容的选项。这些新的信息看似是对观点的补充或者辅助说明，其实也是陷阱。

gre考试阅读干扰选项之误导型。

由于gre阅读题常常需要返回到文章中定位细节来解题，因此题目的选项中就会出现一个看似眼熟，似乎在文章哪里见过，但其实并没有在文中直接出现的推论类选项。考生会受此类选项迷惑而做出错误选择。在此特别提醒考生，细节题的正确选项，必然是能够直接在文章中找到的内容，如果没有出现在文章里，哪怕看上去再正确的选项也极有可能是陷阱。

GRE阅读理解逻辑练习题

1.A new and more aggressive form of the fungus that caused the Irish potatofamine of the nineteenthcentury has recently arisen. However, since this newform of the fungus can be killed by increased application of currently usedfungicides, it is unlikely that the fungus will cause widespread food shortagesin countries that currently rely on potatoes for sustenance.Which of thefollowing, if true, most calls into question the conclusion in the argumentabove?

(A) Though potatoes are an important staple crop in many parts of theworld, people in most countries rely primarily on wheat or rice forsustenance.

(B) Potato farmers in many countries to which the new form of the fungushas spread cannot afford to increase their spending on fungicides.

(C) The new form of the fungus first began to spread when contaminatedpotato seeds were inadvertently exported from a major potato-exportingcountry.

(D) Potato farmers in most countries use several insecticides on theircrops in addition to fungicides of the sort that kill the new form of thefungus.

(E) Most governments have funds set aside that can be used to alleviate theeffects of large-scale disasters such as severe food shortages and floods.

2.As government agencies, faced with budget difficul- ties, reduce theirfunding for scientific research, a greater amount of such research is beingfunded by private foundations. This shift means that research projects likely toproduce controversial results will almost certainly comprise a smallerproportion of all funded research projects, since private foundations, concernedabout their public image, tend to avoid controversy. Which of the following isan assumption on which the argument depends?

(A) Only research that is conducted without concern for the possibility ofgenerating controversy is likely to produce scientifically valid results.

(B) Private foundations that fund scientific research projects usuallyrecognize that controversial results from those projects cannot always beavoided.

(C) Scientists who conduct research projects funded by private foundationsare unlikely to allow the concerns of the funding organizations to influ- encethe manner in which they conduct the research.

(D) Many government agencies are more concerned about their public imagethan are most private foundations.

(E) Government agencies are more willing than are private foundations tofund research projects that are likely to produce controversial results.

3.Juries in criminal trials do not base verdicts on uncor- roboratedtestimony given by any one witness. Rightly so, because it is usually prudent tobe highly skeptical of unsubstantiated claims made by any one person. But then,to be consistent, juries should end an all- too-common practice: convictingdefendants on the basis of an uncorroborated full confession. Which of thefollowing, if true, most strengthens the argument above?

(A) Juries often acquit in cases in which a defendant retracts a fullconfession made before trial.

(B) The process of jury selection is designed to screen out people who havea firm opinion about the defendant's guilt in advance of the trial.

(C) Defendants sometimes make full confessions when they did in fact dowhat they are accused of doing and have come to believe that the prose- cutorhas compelling proof of this.

(D) Highly suggestible people who are accused of wrongdoing sometimesbecome so unsure of their own recollection of the past that they can come toaccept the accusations made against them.

(E) Many people believe that juries should not con- vict defendants whohave not made a full con- fession.

4.Although spinach is rich in calcium, it also contains large amounts ofoxalic acid, a substance that greatly impedes calcium absorption by the body.Therefore, other calcium-containing foods must be eaten either instead of or inaddition to spinach if a person is to be sure of getting enough calcium.

Which of the following, if true, most seriously weakens the argu-mentabove?

(A)Rice, which does not contain calcium, counteracts the effects of oxalicacid on calcium absorption.

(B) Dairy products, which contain even more calcium than spinach does, areoften eaten by people who eat spinach on a regularbasis.

(C) Neither the calcium nor the oxalic acid in spinach is destroyed whenspinach is cooked.

(D) Many leafy green vegetables other than spinach that are rich in calciumalso contain high concentrations of oxalic acid.

(E) Oxalic acid has little effect on the body's ability to absorb nutrientsother than calcium.

5.Joyce: Three years ago the traffic commission modified our town's busiestintersection for better visibility, a commendable effort to cut down on trafficaccidents there. Gary: Over the past three years there have been more, notfewer, traffic accidents per week at that intersection, so the modification hasincreased the likelihood of accidents there The answer to which of the followingquestions would be most useful in evaluating Gary's argument?

(A) What proportion of the town's drivers involved in accidents thatoccurred prior to the modification suffered personal injury in theiraccidents?

(B) How long, on average, had the members of the traffic commission heldtheir offices when the modification was implemented?

(C) Do a majority of the town's residents approve of the trafficcommission's overall performance?

(D) What measures have nearby towns taken within the last three years inorder to improve visibil- ity at dangerous intersections?

(E) How has the volume of traffic at the town's busiest intersectionchanged over the last three years?

6. Women make up the majority of the population in the country, and many ofthe prescriptions written by doctors for tranquilizers are for women patients.The testing of these drugs for efficacy and the calibration of recommendeddoses, however, was done only on men. Not even the animals used to test toxicitywere female. The statements above, if true, best support which of the followingas a conclusion?

(A) Some tranquilizers are more appropriately pre- scribed for women thanfor men.

(B) There have been no reports of negative side effects from prescribedtranquilizers in women

(C) Tranquilizers are prescribed for patients in some instances whendoctors do not feel confident of

their diagnoses.

(D) The toxicity of drugs to women is less than the toxicity of the samedrugs to men.

(E) Whether the recommended dosages of tranquil- izers are optimal forwomen is not known.

7. Gray wolves have been absent from a large national

park for decades. Park officials wish to reestablish the wolves withoutjeopardizing any existing species of wildlife there. Since the park containsadequate prey for the wolves and since the wolves avoid close contact withpeople, reintroducing them would serve the officials' purpose without seriouslyjeopardizing visitors' safety. Each of the following, if true, strengthens theargument above EXCEPT:

(A) The park is so large that wolves will not need to venture into areasfrequented by people.

(B) Rabies is very rare in wolves, and there have been no verified cases ofserious human injuries from nonrabid wild wolves since records have beenkept.

(C) Ranchers in the region near the park have expressed concern that graywolves, if reintro- duced, would sometimes prey on their livestock.

(D) Predation by gray wolves on elk in the park is likely to improve thehealth and viability of the park's elk population as a whole by reducingmalnutrition among the elk.

(E) Wolves do not prey on animals of any endangered species that currentlyinhabit the park.

8. Osteoporosis is a disease that reduces bone mass, lead- ing to fragilebones that break easily. Current treat- ments for osteoporosis such as estrogenor calcitonin help prevent further loss of bone but do not increase bone mass.Since fluoride is known to increase bone mass, administering fluoride toosteoporosis patients would therefore help make their bones less susceptible tobreaking. Which of the following, if true, most seriously weakens the argumentabove?

(A) Most people who suffer from osteoporosis are not aware thatadministration of fluoride can increase bone mass.

(B) Fluoride is added to drinking water in many locations in order tostrengthen the teeth of people who drink the water.

(C) The risk of contracting osteoporosis and other degenerative bonediseases is lessened by exer-

cise and an adequate intake of calcium.

(D) Unlike administration of fluoride, administration of estrogen orcalcitonin is known to cause undesirable side effects for many people.

(E) The new bone mass that is added by the admin- istration of fluoride ismore brittle and less elastic than normal bone tissue.

9. The closest distance from which an asteroid has been photographed usingground-based radar is 2.2 million miles, the distance from which the asteroidToutatis was recently photographed. The closest photograph of an asteroid is ofGaspra, which was photographed from a distance of only 10,000 miles. Which ofthe following can be properly concluded from the statements above?

(A) Toutatis is more likely to collide with the Earththan Gaspra is.

(B) Toutatis, unlike Gaspra, has only recently been discovered.

(C) Asteroids can be photographed only by using ground-based radar.

(D) Ground-based radar photography cannot take photographs of objects muchbeyond 2.2 million miles from Earth.

(E) The photograph of Gaspra was not taken using ground-based radar.

10. Which of the following most logically completes the argument below?Alone among living species, human beings experience adolescence, a period ofaccelerated physical growth prior to full maturity.Whether other hominidspecies, which are now all extinct and are known only through thefossil record,went through adolescence cannot be known, since

(A) the minimum acceleration in physical growth that would indicateadolescence might differ

according to species

(B) the fossil record, though steadily expanding, will always remainincomplete

(C) detecting the adolescent growth spurt requires measurements on the sameindividual at differ- ent ages

(D) complete skeletons of extinct hominids are extremely rare

(E) human beings might be the first species to bene- fit from the survivaladvantages, if any, conferred by adolescence

11. Fossils of the coral Acrocora palmata that date from the last periodwhen glaciers grew and consequently spread from the polar regions are found atocean depths far greater than those at which A. palmata can now survive.Therefore, although the fossilized A. palmata appears indistinguishable from A.palmata now living, it must have differed in important respects to have beenable to live in deep water. The argument depends on the assumption that

(A) no fossils of the coral A. palmata have been found that date fromperiods when glaciers were not spreading from the polar regions

(B) geological disturbances since the last period during which glaciersspread have caused no major downward shift in the location of A. palmatafossils

(C) A. palmata now live in shallow waters in most of the same geographicalregions as those in which deep-lying A. palmata fossils have been found

(D) A. palmata fossils have been found that date from each of the periodsduring which glaciers are known to have spread from the polar region

(E) A. palmata can live at greater depths where the ocean temperature iscolder than they can where the ocean temperature is warmer

12.Conservationists have believed that by concentrating their preservationefforts on habitats rich in an easily surveyed group of species, such as birds,they would thereby be preserving areas rich in overall species diversity. Thisbelief rests on a view that a geographical area rich in one group of specieswill also be rich in the other groups characteristic of the entire regionalclimate zone.

Which of the following findings about widely scattered tracts 10 kilometersby 10 kilometers in a temperate climate zone would most seriously challenge theconservationists' assumptions?

(A) The tracts show little damage from human intrusion and from pollutionby human activities.

(B) Where a certain group of species, such as birds, is abundant, there isalso an abundance of the species, such as insects, on which that group ofspecies feeds, or in the case of plants, of the land and water resources itrequires.

(C) The area of one of the tracts is generally large enough to contain arepresentative sample of the organisms in the region.

(D) There is little overlap between the list of tracts that are rich inspecies of butterflies and the list of those that are rich in species ofbirds.

(E) The highest concentration of individuals of rare species is found wherethe general diversity of species is greatest.
