The refrigerant, starting as a low- temperature, low-pressure vapor, enters a compressor 5 driven by an electric motor. The refrigerant leaves the compressor as a hot, dense vapor and flows through a heat exchanger called the condenser, which transfers heat from the refrigerant to a body of air. Now the refrigerant, as a high-pressure, cooled liquid, confronts 10 a flow restriction which causes the pressure to drop. As the pressure falls, the refrigerant expands and partially vaporizes, becoming chilled. It then passes through a secondheat exchanger, the evaporator, which transfers heat from the air to the refrigerant, reducing the 15 temperature of this second body of air. (126 words)1. According to the passage, the role of the flow restriction in a heat pump is to(A) measure accurately the flow rate of the refrigerant mass at that point(B) compress and heat the refrigerant vapor(C) bring about the evaporation and cooling of refrigerant(D) exchange heat between the refrigerant and the air at that point(E) reverse the direction of refrigerant flow when needed答案：C新GRE逻辑阅读Eight percent of the Earths crust is aluminum, and there are hundreds of aluminum-bearing minerals and vast quantities of the rocks that contain them. The best aluminum ore is bauxite, defined as aggregates of alumi- 5 nous minerals, more or less impure, in which aluminum is present as hydrated oxides. Bauxite is the richest of all those aluminous rocks that occur in large quantities, and it yields alumina, the intermediate product required for the production of aluminum. Alumina also occurs natu- 10 rally as the mineral corundum, but corundum is not found in large deposits of high purity, and therefore it is an impractical source for making aluminum. Most of the many abundant nonbauxite aluminous minerals are silicates, and, like all silicate minerals, they are 15 refractory, resistant to analysis, and extremely difficult to process. The aluminum silicates are therefore generally unsuitable alternatives to bauxite because considerably more energy is required to extract alumina from them.(153 words)4. The author implies that a mineral must either be or readily supply which of the following in order to be classified as an aluminum ore?(A) An aggregate(B) Bauxite(C) Alumina(D) Corundum(E) An aluminum silicateFor the following question, consider each of the choices separately and select all that apply5. The passage supplies information for answering all of the following questions regarding aluminous mineralsA Are aluminum-bearing nonbauxite minerals plentiful?B Do the aluminous minerals found in bauxite contain hydrated oxides?C Are aluminous hydrated oxides found in rocks?6. The author implies that corundum would be used to produce aluminum if(A) corundum could be found that is not contami-nated by silicates(B) the production of alumina could be eliminated as an intermediate step in manufacturing alu-minum(C) many large deposits of very high quality corun-dum were to be discovered(D) new technologies were to make it possible to convert corundum to a silicate(E) manufacturers were to realize that the worlds supply of bauxite is not unlimited答案：C/ABC/C新GRE逻辑阅读Our visual perception depends on the reception of energy reflecting or radiating from that which we wish to perceive. If our eyes could receive and measure infinitely delicate sense-data, we could perceive the 5 world with infinite precision. The natural limits of our eyes have, of course, been extended by mechanical instruments; telescopes and microscopes, for example, expand our capabilities greatly. There is, however, an ultimate limit beyond which no instrument can take us; 10 this limit is imposed by our inability to receive sense- data smaller than those conveyed by an individual quantum of energy. (97 words)9. Which of the following describes a situation most analogous to the situation discussed inthe last sentence?(A) A mathematician can only solve problems the solution of which can be deduced from known axioms.(B) An animal can respond to no command that is more complicated syntactically than any it has previously received.(C) A viewer who has not learned, at least intuitively, the conventions of painting,cannot understand perspective in a drawing.(D) A sensitized film will record no detail on a scale that is smaller than the grain of the film.(E) A shadow cast on a screen by an opaque object will have a sharp edge only if the light source is small or very distant.答案：D新GRE逻辑阅读Of Homers two epic poems, the Odyssey has always been more popular than the Iliad, perhaps because it includes more features of mythology that are accessible to readers. Its subject (to use Maynard Macks 5 categories) is "life-as-spectacle", for readers, diverted by its various incidents, observe its hero Odysseus primarily from without; the tragic Iliad, however, presents "life-as- experience": readers are asked to identify with the mind of Achilles, whose motivations render him a 10 not particularly likable hero. In addition, the Iliad, more than the Odyssey, suggests the complexity of the gods involvement in human actions, and to the extent that modern readers find this complexity a needless complication, the Iliad is less satisfying than the 15 Odyssey, with its simpler ?scheme of divine justice. Finally, since the Iliad presents a historically verifiable action, Troys siege, the poem raises historical questions that are absent from the Odysseys blithely imaginative world. (148 words)10. The author uses Macks categories (lines 4-5)most probably in order to(A) argue that the Iliad should replace the Odyssey as the more popular poem(B) indicate Macks importance as a commentator on the Iliad and the Odyssey(C) suggest one way in which the Iliad and the Odyssey can be distinguished(D) point out some of the difficulties faced by readers of the Iliad and the Odyssey(E) demonstrate that the Iliad and the Odyssey can best be distinguished by comparing their respective heroes11. The passage is primarily concerned with(A) distinguishing arguments(B) applying classifications(C) initiating a debate(D) resolving a dispute(E) developing a contrast12. It can be inferred from the passage that a reader of the Iliad is likely to have trouble identifying with the poems hero for which of the following reasons?(A) The hero is eventually revealed to be unheroic.(B) The hero can be observed by the reader only from without.(C) The heros psychology is not historically verifiable.(D) The heros emotions often do not seem appealing to the reader.(E) The heros emotions are not sufficiently various to engage the readers attention.答案：C/E/D
