As it was published in 1935, Mules and Men, Zora Neale Hurston s landmark collection of folktales, may not have been the book that its author first had in mind. In this anthropological study, Hurston describes in detail the people who tell the stories, often even inserting herself into the storytelling scene. Evidently, however, Hurston had prepared another version, a manuscript that was recently discovered and published after having been forgotten since 1929. This version differs from Mules and Men in that it simply records stories, with no descriptive or interpretive information.

While we cannot know for certain why Hurston’s original manuscript went unpublished during her lifetime, it may have been because publishers wanted something more than a transcription of tales. Contemporary novelist and critic John Edgar Wideman has described Black literature as the history of a writing that sought to escape its frame, in other words, as the effort of Black writers to present the stories of Black people without having to have a mediating voice to explain the stories to a non-Black audience. In this, Hurston may have been ahead of her time.

阅读-选项

1.

Select the sentence that suggests a possible reason why Hurston wrote the version of Mules and Men that was published in 1935.

2.

The passage suggests that Hurston may have done which of the following in preparing her original version?

A. Discussed her mode of presentation with her publisher before writing the first draft, in order to reduce the possibility of misunderstanding.

B. Shortened her presentation of the stories to the bare minimum in order to be able to present more folklore material.

C. Put it aside for several decades in order to maximize its potential audience when it was published.

D. Reluctantly agreed to reshape it in order to take out various elements with which her publisher had been dissatisfied.

E. Chose not to include editorial commentary, in order to present the stories on their own terms.

Much recent work has examined the claim that women encounter increasing obstacles relative to men as they move up the organizational ladder in business. This proposition, which we term the increasing-disadvantage model, is a core element of the popular glass ceiling metaphor. Despite continued widespread public acceptance of the glass ceiling idea and some consistent findings, most research to date has failed to support the increasing-disadvantage model. Indeed, several studies based on private-sector firms find that women’ s mobility prospects improve, rather than decline, as they climb upward in corporate hierarchies. In the public sector, researchers have found either no sex differences in mobility or a larger female disadvantage in lower grades.

Comparing cross-sectional national samples of workers, Baxter and Wright found no evidence in the United States, and only limited evidence in Sweden and Australia, that women’ s probability of being located in a higher versus a lower hierarchical level declined relative to men’ s at higher levels. Taken together, these findings suggest that the glass ceiling may be a myth. Women’ s scarcity in top organizational ranks may simply represent the cumulative effect of a constant-or even decreasing-disadvantage at successive hierarchical levels.

阅读-选项

A. compare two explanations for a recurring problem

B. It correlates with findings on women’ s mobility from most other counties.

C. It suggests important cultural similarities between these countries.

D. It points to a phenomenon not widely recognized in these countries.

E. It helps explain the persistence of the glass ceiling.

3.

The author of the passage and those accepting the “proposition” would most likely agree with which of the following?

A. Lower down on the organizational ladder, women tend to experience fewer disadvantages than they do at higher levels.

B. Women experience no more disadvantages in moving up the organizational ladder than do men.

C. The degree of disadvantage experiences by women remains constant as women move up the organizational ladder.

D. The obstacles to women’ s advancement vary significantly from country to country.

E. Women face some disadvantage at each stage of the organizational ladder.

The waters east of Cape Hangklip were once the center of a lucrative wild-caught abalone fishery, but illegal fishing in the mid-1990s escalated to such levels that the recreational fishery was closed in 2003. When abalones did not rebound, commercial fishing was also banned. Continual declines in abalone were attributed to poaching, but an invasion by rock lobsters during the early 1990s probably intensified the trend. Rock lobsters prey on sea urchins, and increased rock lobster densities coincided with significant decreases in urchins. In that area, urchins feed largely by trapping drift kelp, and in doing so provide juvenile abalone with both protective shelter and nourishment. Without urchins’ presence, juvenile abalones are less likely to survive to adulthood.

阅读-选项

1.

According to the passage, since the early 1990s, sea urchins in the waters east of Cape Hangklip have

A. significantly changed their feeding habits

B. suffered increased predation from a certain species

C. experienced increased competition for kelp, their main source of nourishment

D. seen a sharp decline in the availability of kelp, due to environmental changes

E. rebounded as commercial fishing in the region has declined

2.

According to the passage, which of the following is a true statement about the feeding behaviors of sea urchins

A. They change according to the type of food available in an area.

B. They are responsible for the decline of abalones in some regions.

C. They have a significant impact on the young of another species.

D. They make sea urchins more vulnerable to potential predators.

E. They result in marked decline in certain regions.

Which of the following statements about the Closing of the ‘‘recreational fishery’’ is supported by the passage?

A. It was a measure taken in response to the invasion of the area by rock lobsters.

B. It had unintended effects on the region’s population of sea urchins.

C. It was enacted after the banning of commercial fishing in the region.

D. It did not stem the decline of abalone in the region.

E. It had a short-lived effect on the area’s abalone population.

4.

It can be inferred from the passage that the decline of abalones in the waters east of Cape Hangklip was probably due in part to

A. an increase in the area’s population of rock lobsters

B. illegal harvesting of adult abalones in the area
