8、that areAnswer: -Q4 to Q6:Prior to 1965 geologists assumedthat the two giant rock plates meeting atthe San Andreas Fault generate heatLine through friction as they grind past each(5) other, but in 1965 Henyey found thattemperatures in drill holes near thefault were not as elevated as hadbeen expecte

9、d. Some geologistswondered whether the absence of(10) friction-generated heat could beexplained by the kinds of rock com-posing the fault. Geologists pre-1965assumptions concerning heat gen-erated in the fault were based on(15) calculations about common varieties ofrocks, such as limestone and grani

10、te;but “weaker” materials, such as clays,had already been identified in samplesretrieved from the fault zone. Under(20) normal conditions, rocks composed ofclay produce far less friction than doother rock types.In 1992 Byerlee tested whetherthese materials would produce friction(25) 10 to 15 kilomet

11、ers below the Earthssurface. Byerlee found that when claysamples were subjected to the thou-sands of atmospheres of pressurethey would encounter deep inside the(30) Earth, they produced as much frictionas was produced by other rock types.The harder rocks push against eachother, the hotter they becom

12、e; in otherwords, pressure itself, not only the(35) rocks properties, affects frictionalheating. Geologists therefore won-dered whether the friction between theplates was being reduced by pocketsof pressurized water within the fault thatpush the plates away from each other.-Q4:The passage suggests w

17、ltC. established the superiority of a particular technique for evaluating data concerning friction in the San Andreas FaultD. suggested that geologists had inaccurately assumed that giant rock plates that meet at the San Andreas Fault generate heat through frictionE. confirmed geologists assumptions

18、 about the amount of friction generated by common varieties of rocks, such as limestone and graniteAnswer: -Q7:For similar cars and drivers, automobile insurance for collision damage has always cost more in Greatport than in Fairmont. Police studies, however, show that cars owned by Greatport reside

19、nts are, on average, slightly less likely to be involved in a collision than cars in Fairmont. Clearly, therefore, insurance companies are making a greater profit on collision-damage insurance in Greatport than in Fairmont.Which of the following is an assumption on which the argument depends?A. Repa

20、iring typical collision damage does not cost more in Greatport than in Fairmont.B. There are no more motorists in Greatport than in Fairmont.C. Greatport residents who have been in a collision are more likely to report it to their insurance company than Fairmont residents are.D. Fairmont and Greatpo

21、rt are the cities with the highest collision-damage insurance rates.E. The insurance companies were already aware of the difference in the likelihood of collisions before the publication of the police reports.Answer: -Q8:Sulfur dioxide, a major contributor to acid rain, is an especially serious poll

22、utant because it diminishes the respiratory systems ability to deal with all other pollutants.A. an especially serious pollutant because it diminishes the respiratory systems ability to dealB. an especially serious pollutant because of diminishing the respiratory systems capability of dealingC. an e

23、specially serious pollutant because it diminishes the capability of the respiratory system in dealingD. a specially serious pollutant because it diminishes the capability of the respiratory system to dealE. a specially serious pollutant because of diminishing the respiratory systems ability to dealA

24、nswer: -Q9:Although exposure to asbestos is the primary cause of mesothelioma, a slow-developing cancer, researchers believe that infection by the SV40 virus is a contributing cause, since in the United States 60 percent of tissue samples from mesotheliomas, but none from healthy tissue, contain SV4

25、0. SV40 is a monkey virus; however, in 1960 some polio vaccine was contaminated with the virus. Researchers hypothesize that this vaccine was the source of the virus found in mesotheliomas decades later.Which of the following, if true, most strongly supports the researchers hypothesis?A. SV40 is wid

26、ely used as a research tool in cancer laboratories.B. Changes in the technique of manufacturing the vaccine now prevent contamination with SV40.C. Recently discovered samples of the vaccine dating from 1960 still show traces of the virus.D. In a small percentage of cases of mesothelioma, there is no

27、 history of exposure to asbestos.E. In Finland, where the polio vaccine was never contaminated, samples from mesotheliomas do not contain SV40.Answer: -Q10 to Q13:One proposal for pre- serving rain forests is to promote the adoption ofLine new agricultural technolo-(5) gies, such as improvedplant va

28、rieties and use ofchemical herbicides, whichwould increase productivityand slow deforestation by(10) reducing demand for newcropland. Studies haveshown that farmers in developing countries who have achieved certain levels(15) of education, wealth, andsecurity of land tenure aremore likely to adopt s

29、uchtechnologies. But thesestudies have focused on(20) villages with limited landthat are tied to a marketeconomy rather than onthe relatively isolated, self-sufficient communities with(25) ample land characteristic ofrain-forest regions. A recent study of the Tawahka peopleof the Honduran rain fores

30、tfound that farmers with some (30) formal education were more likely to adopt improved plant varieties but less likely touse chemical herbicidesand that those who spoke(35) Spanish (the language ofthe market economy) weremore likely to adopt bothtechnologies. Nonlandwealth was also associated(40) wi

31、th more adoption of bothtechnologies, but availabilityof uncultivated land reducedthe incentive to employ theproductivity-enhancing tech-(45) nologies. Researchersalso measured land-tenuresecurity: in Tawahkasociety, kinship ties are a more important indicator of (50) this than are legal propertyrig

32、hts, so researchersmeasured it by a house-holds duration of residencein its village. They found(55) that longer residence cor-related with more adoptionof improved plant varietiesbut less adoption ofchemical herbicides.-Q10:The primary purpose of the passage is toA. evaluate the likelihood that a pa

33、rticular proposal, if implemented, would ultimately succeed in achieving its intended resultB. question the assumption that certain technological innovations are the most effective means of realizing a particular environmental objectiveC. discuss the progress of efforts to encourage a particular tra

34、ditional society to adopt certain modern agricultural methodsD. present the results of new research suggesting that previous findings concerning one set of conditions may not be generalizable to another set of conditionsE. weigh the relative importance of three factors in determining whether a parti

35、cular strategy will be successfulAnswer: -Q11:According to the passage, the proposal mentioned in line 1 is aimed at preserving rain forests by encouraging farmers in rain-forest regions to do each of the following EXCEPTA. adopt new agricultural technologiesB. grow improved plant varietiesC. decrea

36、se their use of chemical herbicidesD. increase their productivityE. reduce their need to clear new land for cultivationAnswer: -Q12:The passage suggests that in the study mentioned in line 27 the method for gathering information about security of land tenure reflects which of the following pairs of

37、assumptions about Tawahka society?A. The security of a households land tenure depends on the strength of that households kinship ties, and the duration of a households residence in its village is an indication of the strength of that households kinship ties.B. The ample availability of land makes se

38、curity of land tenure unimportant, and the lack of a need for secure land tenure has made the concept of legal property rights unnecessary.C. The strength of a households kinship ties is a more reliable indicator of that households receptivity to new agricultural technologies than is its quantity of

39、 nonland wealth, and the duration of a households residence in its village is a more reliable indicator of that households security of land tenure than is the strength of its kinship ties.D. Security of land tenure based on kinship ties tends to make farmers more receptive to the use of improved pla

40、nt varieties, and security of land tenure based on long duration of residence in a village tends to make farmers more receptive to the use of chemical herbicides.E. A household is more likely to be receptive to the concept of land tenure based on legal property rights if it has easy access to uncult

41、ivated land, and a household is more likely to uphold the tradition of land tenure based on kinship ties if it possesses a significant degree of nonland wealth.Answer: -Q13:The findings of the study mentioned in line 27, if valid for rain-forest regions in general, suggest that which of the followin

42、g is an obstacle most likely to be faced by those wishing to promote rain-forest preservation by implementing the proposal mentioned in line 1?A. Lack of legal property rights tends to discourage local farmers from investing the time and resources required to successfully implement new agricultural

43、technologies.B. The ability to evaluate the wider economic ramifications of adopting new aricultural technologies depends on a relatively high level of formal education.C. Isolation from the market economy tends to restrict local farmers access to new agricultural technologies that could help them t

44、o increase their productivity.D. Ready availability of uncultivated land tends to decrease local farmers incentive to adopt new agricultural technologies that would reduce their need to clear new land for cultivation.E. Traditions of self-sufficiency and reliance on kinship ties tend to diminish local farmers receptivity to new agricultural technologies introduced by people from outside the local community.Answer: -Q14:Yeasts capable of leavening bread are widespread, and in the many centuries during which the ancient Egyptians made
