GRE阅读如何保持稳定读文章和解题速度?

GRE阅读切忌求快和犹豫不决

提醒各位备考GRE的同学,切记稳中求快,而切忌走极端——或是盲目求快,忽视文章中的重要信息;或是畏头畏尾不敢舍弃。如果一味求快,而忽视了文中重要的信息,往往得不偿失,虽然练就了一目十行的本领,但是却忽略了对文章主干的提炼。反之,如果过分谨慎,把所有信息都当做重点信息来处理,恐怕在时间上花费是无法达到GRE阅读的要求的。

GRE阅读注重逻辑感培养

此外,GRE阅读中应该注重逻辑感的培养,包括作者行文套路,文章结构和主题。不少同学往往本末倒置,过分注重文章中细节的描述,而却忽略了对文章的整体把握。从而导致GRE阅读时间分配的严重不合理,甚至在考场上没有时间去思考给出的问题。

虽然GRE考试中的阅读部分大约每4分钟就需要看完一篇长文章,而且文章内容涉猎比较广泛,晦涩的长难句也不少,但是GRE阅读的考查点还是着眼于逻辑思维能力的考查,要想在GRE阅读中取得高分,就一定要针对自己的阅读思维多做训练。

Whether the languages of the ancient American peoples were used for expressing abstract universal concepts can be clearly answered in the case of Nahuatl. Nahuatl, like Greek and German, is a language that allows the formation of extensive compounds. By the combination of radicals or semantic elements, single compound words can express complex conceptual relations, often of an abstract universal character.

The tlamatinime (“those who know”) were able to use this rich stock of abstract terms to express the nuances of their thought. They also availed themselves of other forms of expression with metaphorical meaning, some probably original, some derived from Toltec coinages. Of these forms the most characteristic in Nahuatl is the juxtaposition of two words that, because they are synonyms, associated terms, or even contraries, complement each other to evoke one single idea. Used as metaphor, the juxtaposed terms connote specific or essential traits of the being they refer to, introducing a mode of poetry as an almost habitual form of expression.

17. A main purpose of the passage is to

(A) delineate the function of the tlamatinime in Nahuatl society

(B) explain the abstract philosophy of the Nahuatl thinkers

(C) argue against a theory of poetic expression by citing evidence about the Nahuatl

(D) explore the rich metaphorical heritage the Nahuatl received from the Toltecs

(E) describe some conceptual and aesthetic resources of the Nahuatl language

18. According to the passage, some abstract universal ideas can be expressed in Nahuatl by

(A) taking away from a word any reference to particular instances

(B) removing a word from its associations with other words

(C) giving a word a new and opposite meaning

(D) putting various meaningful elements together in one word

(E) turning each word of a phrase into a poetic metaphor

19. It can be inferred solely from the information in the passage that

(A) there are many languages that, like Greek or German, allow extensive compounding

(B) all abstract universal ideas are ideas of complex relations

(C) some record or evidence of the thought of the tlamatinime exists

(D) metaphors are always used in Nahuatl to express abstract conceptual relationships

(E) the abstract terms of the Nahuatl language are habitually used in poetry

Many theories have been formulated to explain the role of grazers such as zooplankton in controlling the amount of planktonic algae (phytoplankton) in lakes. The first theories of such grazer control were merely based on observations of negative correlations between algal and zooplankton numbers. A low number of algal cells in the presence of a high number of grazers suggested, but did not prove, that the grazers had removed most of the algae. The converse observation, of the absence of grazers in areas of high phytoplankton concentration, led Hardy to propose his principle of animal exclusion, which hypothesized that phytoplankton produced a repellent that excluded grazers from regions of high phytoplankton concentration. This was the first suggestion of algal defenses against grazing.

Perhaps the fact that many of these first studies considered only algae of a size that could be collected in a net (net phytoplankton), a practice that overlooked the smaller phytoplankton (nannoplankton) that we now know grazers are most likely to feed on, led to a de-emphasis of the role of grazers in subsequent research. Increasingly, as in the individual studies of Lund, Round, and Reynolds, researchers began to stress the importance of environmental factors such as temperature, light, and water movements in controlling algal numbers. These environmental factors were amenable to field monitoring and to simulation in the laboratory. Grazing was believed to have some effect on algal numbers, especially after phytoplankton growth rates declined at the end of bloom periods, but grazing was considered a minor component of models that predicted algal population dynamics (population dynamics: 种群动态;人口动态).

The potential magnitude of grazing pressure on freshwater phytoplankton has only recently been determined empirically. Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers. The high estimates of grazing pressure postulated by these researchers were not fully accepted, however, until the grazing rates of zooplankton were determined directly in the field, by means of new experimental techniques. Using a specially prepared feeding chamber, Haney was able to record zooplankton grazing rates in natural field conditions. In the periods of peak zooplankton abundance, that is, in the late spring and in the summer, Haney recorded maximum daily community grazing rates, for nutrient-poor lakes and bog lakes, respectively, of 6.6 percent and 114 percent of daily phytoplankton production. Cladocerans had higher grazing rates than copepods, usually accounting for 80 percent of the community grazing rate. These rates varied seasonally, reaching the lowest point in the winter and early spring. Haney’s thorough research provides convincing field evidence that grazers can exert significant pressure on phytoplankton population.

20. The author most likely mentions Hardy’s principle of animal exclusion in order to

(A) give an example of one theory about the interaction of grazers and phytoplankton

(B) defend the first theory of algal defenses against grazing

(C) support the contention that phytoplankton numbers are controlled primarily by environmental factors

(D) demonstrate the superiority of laboratory studies of zooplankton feeding rates to other kinds of studies of such rates

(E) refute researchers who believed that low numbers of phytoplankton indicated the grazing effect of low numbers of zooplankton

21. It can be inferred from the passage that the “first theories” of grazer control mentioned in line 4 would have been more convincing if researchers had been able to

(A) observe high phytoplankton numbers under natural lake conditions

(B) discover negative correlations between algae and zooplankton numbers from their field research

(C) understand the central importance of environmental factors in controlling the growth rates of phytoplankton

(D) make verifiable correlations of cause and effect between zooplankton and phytoplankton numbers

(E) invent laboratory techniques that would have allowed them to bypass their field research concerning grazer control

22. Which of the following, if true, would call into question Hardy’s principle of animal exclusion?

(A) Zooplankton are not the only organisms that are affected by phytoplankton repellents.

(B) Zooplankton exclusion is unrelated to phytoplankton population density.

(C) Zooplankton population density is higher during some parts of the year than during others.

(D) Net phytoplankton are more likely to exclude zooplankton than are nannoplankton.

(E) Phytoplankton numbers can be strongly affected by environmental factors.

23. The author would be likely to agree with which of the following statements regarding the pressure of grazers on phytoplankton numbers?

I. Grazing pressure can vary according to the individual type of zooplankton.

II. Grazing pressure can be lower in nutrient-poor lakes than in bog lakes.

III. Grazing tends to exert about the same pressure as does temperature.

(A) I only

(B) III only

(C) I and II only

(D) II and III only

(E) I, II, and III

24. The passage supplies information to indicate that Hargrave and Geen’s conclusion regarding the grazing pressure exerted by zooplankton on phytoplankton numbers was most similar to the conclusion regarding grazing pressure reached by which of the following researchers?

(A) Hardy

(B) Lund

(C) Round

(D) Reynolds

(E) Haney

25. It can be inferred from the passage that one way in which many of the early researchers on grazer control could have improved their data would have been to

(A) emphasize the effects of temperature, rather than of light, on phytoplankton

(B) disregard nannoplankton in their analysis of phytoplankton numbers

(C) collect phytoplankton of all sizes before analyzing the extent of phytoplankton concentration

(D) recognize that phytoplankton other than net phytoplankton could be collected in a net

(E) understand the crucial significance of net phytoplankton in the diet of zooplankton

26. According to the passage, Hargrave and Geen did which of the following in their experiments?

(A) They compared the grazing rates of individual zooplankton species in the laboratory with the natural grazing rates of these species.

(B) The hypothesized about the population density of grazers in natural habitats by using data concerning the population density of grazers in the laboratory.

(C) They estimated the community grazing rates of zooplankton in the laboratory by using data concerning the natural community grazing rates of zooplankton.

(D) They estimated the natural community grazing rates of zooplankton by using data concerning the known population density of phytoplankton.

(E) They estimated the natural community grazing rates of zooplankton by using laboratory data concerning the grazing rates of individual zooplankton species.

27. Which of the following is a true statement about the zooplankton numbers and zooplankton grazing rates observed in Haney’s experiments?

(A) While zooplankton numbers began to decline in August, zooplankton grazing rates began to increase.

(B) Although zooplankton numbers were high in May, grazing rates did not become high until January.

(C) Both zooplankton numbers and grazing rates were higher in December than in November.

(D) Both zooplankton numbers and grazing rates were lower in March than in June.
