A mysterious phenomenon is the ability of over-water migrants to travel on course. Birds, bees, and other species can keep track of time without any sensory cues from the outside world, and such biological clocks clearly contribute to their compass sense. For example, they can use the position of the Sun or stars, along with the time of day , to find north. But compass sense alone cannot explain how birds navigate the ocean: after a flock traveling east is blown far south by a storm, it will assume the proper northeasterly course to compensate. Perhaps, some scientists thought, migrants determine their geographic position on Earth by celestial navigation, almost as human navigators use stars and planets, but this would demand of the animals a fantastic map sense. Researchers now know that some species have a magnetic sense, which might allow migrants to determine their geographic location by detecting variations in the strength of the Earths magnetic field.
17. The main idea of the passage is that
migration over land requires a simpler explanation than migration over water does
the means by which animals migrate over water are complex and only partly understood
the ability of migrant animals to keep track of time is related to their magnetic sense
knowledge of geographic location is essential to migrants with little or no compass sense
explanations of how animals migrate tend to replace, rather than build on, one another
18. It can be inferred from the passage that if the flock of birds described in lines 8-12 were navigating by compass sense alone, they would, after the storm, fly
east
north
northwest
south
southeast
19. In maintaining that migrating animals would need a fantastic map sense to determine their geographic position by celestial navigation, the author intends to express
admiration for the ability of the migrants
skepticism about celestial navigation as an explanation
certainly that the phenomenon of migration will remain mysterious
interest in a new method of accounting for over-water migration
surprise that animals apparently navigate in much the same way that human beings do
20. Of the following descriptions of migrating animals, which most strongly suggests that the animals are depending on magnetic cues to orient themselves?
Pigeons can properly readjust their course even when flying long distances through exceedingly dense fogs.
Bison are able to reach their destination by passing through a landscape that has been partially altered by a recent fire.
Elephants are able to find grounds that some members of the herd have never seen before.
Swallows are able to return to a given spot at the same time every year.
Monarch butterflies coming from different parts of North America are able to arrive at the same location each winter.
Roger Rosenblatts book Black Fiction, in attempting to apply literary rather than sociopolitical criteria to its subject, successfully alters the approach taken by most previous studies. As Rosenblatt notes, criticism of Black writing has often served as a pretext for expounding on Black history. Addison Gayles recent work, for example, judges the value of Black fiction by overtly political standards, rating each work according to the notions of Black identity which it propounds.
Although fiction assuredly springs from political circumstances, its authors react to those circumstances in ways other than ideological, and talking about novels and stories primarily as instruments of ideology circumvents much of the fictional enterprise. Rosenblatts literary analysis discloses affinities and connections among works of Black fiction which solely political studies have overlooked or ignored.
Writing acceptable criticism of Black fiction, however, presupposes giving satisfactory answers to a number of questions. First of all, is there a sufficient reason, other than the racial identity of the authors, to group together works by Black authors? Second, how does Black fiction make itself distinct from other modern fiction with which it is largely contemporaneous? Rosenblatt shows that Black fiction constitutes a distinct body of writing that has an identifiable, coherent literary tradition. Looking at novels written by Blacks over the last eighty years, he discovers recurring concerns and designs independent of chronology. These structures are thematic, and they spring, not surprisingly, from the central fact that the Black characters in these novels exist in a predominantly White culture, whether they try to conform to that culture of rebel against it.
Black Fiction does leave some aesthetic questions open. Rosenblatts thematic analysis permits considerable objectivity; he even explicitly states that it is not his intention to judge the merit of the various worksyet his reluctance seems misplaced, especially since an attempt to appraise might have led to interesting results. For instance, some of the novels appear to be structurally diffuse. Is this a defect, or are the authors working out of, or trying to forge, a different kind of aesthetic? In addition, the style of some Black novels, like Jean Toomers Cane, verges on 接近于v.接近, 近乎) expressionism or surrealism; does this technique provide a counterpoint to the prevalent theme that portrays the fate against which Black heroes are pitted, a theme usually conveyed by more naturalistic modes of expression?
In spite of such omissions, what Rosenblatt does include in his discussion makes for an astute and worthwhile study. Black Fiction surveys a wide variety of novels, bringing to our attention in the process some fascinating and little-known works like James Weldon Johnsons Autobiography of an Ex-Colored Man. Its argument is tightly constructed, and its forthright, lucid style exemplifies levelheaded and penetrating criticism.
21. The author of the passage objects to criticism of Black fiction like that by Addison Gayle because it
emphasizes purely literary aspects of such fiction
misinterprets the ideological content of such fiction
misunderstands the notions of Black identity contained in such fiction
substitutes political for literary criteria in evaluating such fiction
ignores the interplay between Black history and Black identity displayed in such fiction
22. The author of the passage is primarily concerned with
evaluating the soundness of a work of criticism
comparing various critical approaches to a subject
discussing the limitations of a particular kind of criticism
summarizing the major points made in a work of criticism
explaining the theoretical background of a certain kind of criticism
23. The author of the passage believes that Black Fiction would have been improved had Rosenblatt
evaluated more carefully the ideological and historical aspects of Black fiction
attempted to be more objective in his approach to novels and stories by Black authors
explored in greater detail the recurrent thematic concerns of Black fiction throughout its history
established a basis for placing Black fiction within its own unique literary tradition
assessed the relative literary merit of the novels he analyzes thematically
24. The authors discussion of Black Fiction can be best described as
pedantic and contentious
critical but admiring
ironic and deprecating
argumentative but unfocused
stilted and insincere
25. It can be inferred that the author of the passage would be LEAST likely to approve of which of the following?
An analysis of the influence of political events on the personal ideology of Black writes
A critical study that applies sociopolitical criteria to autobiographies by Black authors
A literary study of Black poetry that appraises the merits of poems according to the political acceptability of their themes
An examination of the growth of a distinct Black literary tradition within the context of Black history
A literary study that attempts to isolate aesthetic qualities unique to Black fiction
26. The author of the passage uses all of the following in the discussion of Rosenblatts book EXCEPT
rhetorical questions
specific examples
comparison and contrast
definition of terms
personal opinion
27. The author of the passage refers to James Weldon Johnsons Autobiography of an Ex-Colored Man most probably in order to
point out affinities between Rosenblatts method of thematic analysis and earlier criticism
clarify the point about expressionistic style made earlier in the passage
qualify the assessment of Rosenblatts book made in the first paragraph of the passage
illustrate the affinities among Black novels disclosed by Rosenblatts literary analysis
give a specific example of one of the accomplishments of Rosenblatts work
