The population of elephant seals, reduced by hunting to perhaps a few dozen animals early in this century, has soared under federal protection during the last few decades. However, because the species repopulated itself through extensive inbreeding, it now exhibits a geic uniformity that is almost unparalleled in other species of mammals, and thus it is in far greater danger of being extinct than are most other species. Given the information in the passage above, which of the following is most likely the reason that other species of mammals are less likely than elephant seals to bee extinct? (A) Other species of mammals have large populations, so the loss of a few members of the species is not significant. (B) Other species of mammals have increased their knowledge of dangers though the experience of generation after generation of animals. (C) In other species of mammals, hunters can readily distinguish between males and females or between young animals and adults. (D) In other species of mammals, some members of the species are geically better equipped to withstand a disease or event that destroys other members of the species. (E) Other species of mammals have retained habits of caution and alertness because they have not been protected as endangered species. 2． 解釋矛盾。 英文標(biāo)志詞： explain, reason, account for, provide a rationale for, reconcile the discrepancy/paradox. 讀文章方式：不要關(guān)心文章的推導(dǎo)過(guò)程，只需從文中拎出所要解釋的對(duì)象說(shuō)它對(duì)即可，用常識(shí)解題。 (C) 未獲得 t 的藥物治療。 not + weaken 例 1. In the 1960’s longterm studies of primate behavior often used as subjects tamaris, small monkeys that were thought ideal because they require only small cages, breed frequently, and grow quickly. Field studies were not used because they were costly and difficult. Tamarinds were kept caged in malefemale pairs, because otherwise, serious fights erupted between unrelated females. On the basis of the fact that breeding occurred, tamarinds were viewed as monogamous. The view taken by the researchers concerning the monogamy of tamarinds deepened on a questionable assumption. Which of the following could have served as that assumption? (A) The suppression of fighting between related females serves to protect their mon geic inheritance. (B) Adult male tamarinds contribute to the care of tamarind infants. (C) The social system of tamarinds requires monogamous pairing. (D) Male tamarind monkeys do not display aggressive behavior in the wild. (E) The way the tamarinds were kept in cages did not affect their mating behavior. 例 2. Twenty percent of all energy consumed in the United States is consumed by home appliances. If appliances that are twice as energyefficient as those currently available are produced, this figure will eventually be reduced to about ten percent. The argument above requires which of the following assumption? (A) Homeappliance usage would not increase along with the energy efficiency of the appliances. (B) It would not be expensive to produce home appliances that are energyefficient. (C) Homeappliance manufacturers now have the technology to produce appliances that are twice as energyefficient as those currently available. (D) The cost of energy to the consumer world rise with increase in the energy efficiency of home appliances. (E) The percentage of energy consumed by home appliances will increase if existing appliances are not replaced by more energyefficient models. 例 3. Inspection system X and inspection system Y, though based on different principles, each detect all product flaws but they each also erroneously reject three percent of flawless products. Since false rejections are very costly, monkey will be saved by installing both systems, instead of either one or the other, and rejecting only products found flawed by both. The argument above requires which of the following assumption? (A) The three percent of flawless products that system X rejects are not all the same products, piece for piece, that system Y erroneously rejects. (B) It is less costly to accept a flawed product than to reject a flawless one. (C) In their price range, system as X and Y are the least errorprone inspection systems on the market. (D) Whichever system performs the second inspection needs to inspect only products not rejected by the first system. (E) Any way of detecting flaws, other than by using either system X or system Y, requires plete disassembly of the products. 例 4. 染上 t 這種病的人一次又一次重復(fù)發(fā)作。 橋梁型。 1. 削弱。 A is result of B。 BC? 例 4. The excessive number of safety regulations that the federal government has placed on industry poses more serious hardships for big businesses than for small ones. Since large panies do everything on a more massive scale, they must alter more plex operations and spend much more money to meet government requirements. Which of the following, if true, would most weaken the argument above? (A) Small panies are less likely than large panies to have the capital reserve for improvements. (B) The operations of small panies frequently rely on the same technologies as the operations of large panies. (C) Safety regulation codes are uniform, established without reference to size of pany. (D) Large panies typically have more of their profits invested in other business than do small panies. (E) Large panies are in general more likely than small panies to diversity the markets and products. 4. 評(píng)價(jià)。 A— B （ 2） B 存在。 A— B 例 1． New Jersey has one of the lowest motor vehicle fatality rates in the country, and it is one of the few states that require extensive annual automobile safety inspections. Therefore, all states should adopt similar safety inspection procedures. The argument above is based on which of the following a
