Ernest Hemingway, an American author who won the Nobel Prize in Literature in 1954, is well known for his distinctive writing style, characterized by economy and understatement, and exact portrayal of macho characters, which attracts many critics' attention and earns the title of Hemingway hero.This paper finds that the characteristics of the conventional Hemingway hero can be traced on the female character instead of the male character in"Hills Like White Elephants". Through analyzing the characteris- tics of Hemingway hero on the female character, the author concludes that the female character in"Hills Like White Elephants"of- fers a unique and unconventional example of Hemingway hero and deserves more attention in the research of Hemingway 's charac- terization. 展开更多

Hills Like White Elephants is written by Ernest Hemingway,who is one of the greatest representatives of the American literature.Ingenious symbolism and efficient and powerful dialogue combine to make the story a representative of Hemingway's short stories.What is especially successful and notable about this book is that it fully represents the author’s style of the"iceberg",where space of multi-profound meanings is hidden in the simple plot.It is so impressive because Ernest Hemingway has succeeded in presenting the deep meaning as close as possible to the readers through the simple and concise words.This paper tries to carry out a research on the narrative rhetoric of Hills Like White Elephants from three aspects.The first part begins with the analysis of its narrator and narrative situation.The second part centers on the focalization.In the last part,the emphasis is put on the narrative modes. 展开更多

Deciphering hydrocarbon generation and accumulation stage is of significance to understand oil and gas evolution and seek exploration targets.Taking the Upper Paleozoic buried-hills in the Huanghua Depression,Bohai Bay Basin,as a case study,hydrocarbon generation environment and detailed accumulation process are revealed by fluid inclusions observations,Laser Raman spectroscopy,Fourier Infrared spectroscopy,and K-Ar isotope measurements.The results show that both oil and gas inclusion were captured in the quartz overgrowth,dissolved feldspar and calcite microfractures,showing blue to dark brown fluoresce.The grains containing oil inclusions index(GOI)of oil,oil&gas and gas being 25%,65%,and 10%and the inclusions with abundant methyl groups and short chains,both indicate high thermal maturity.One series of fluids inclusion is generally observed,evidenced by the concentrated homogenization temperature of 135-145℃ and salinity of 3%-15 w.t.%NaCl equiv,indicating one primary charging stage.The gas and gas&liquid inclusions mainly contain CH_(4),with also peaks indicating CO_(2) and N_(2.)The Carboniferous and Permian biomarkers show reducing environment with brackish water,with organic matter sources both from marine and continental.The relative content ofααα20RC_(27),ααα20RC_(28),andααα20RC_(29) exhibit source contributions both from algae and higher plants,and mainly of II2 to III kerogen.Both coal derived gas and oil associated hydrocarbons are identified from most of the buried-hills.Combining the fluid homogenization temperature and salinity,as well as the thermal evolution history,the hydrocarbon generated from the Upper Paleozoic was concentrated at the end of the Eocene(40 Ma±),while the beginning of charging is 60 Ma±.The Wumaying Buried-hill is of only coal derived gas and has potential for inner coal measure natural gas exploration.The results provide a detailed understanding of hydrocarbon accumulations in the study area,which can also be reference for improving petroleum exploration efficiency in similar basins. 展开更多

Superconducting magnetic levitation performance, including levitation force and guidance force, is important for the application of high-temperature super- conducting maglev. Both of them are not only affected by different arrays of superconductors and magnets, but also by the thickness of the iron shim between permanent magnets. In order to obtain the best levitation performance, the magnetic field distribution, levitation force, and guidance force of a new type of three magnetic hills of permanent magnet guideway with iron shim of different thicknesses (4, 6, and 8 mm) are discussed in this paper. Simulation analysis and experiment results show that the guideway with iron shim of 8 mm thickness possesses the strongest magnetic field and levitation performance when the suspension gap is larger than 10 mm. However, with the decreasing of suspension gap, the guideway with iron shim of 4 mm thickness possesses the best levitation performance. The phenomena can be attributed to the density distribution of flux and magnetization of iron shim. 展开更多

Ernest Hemingway's short story of Hills Like White Elephants is a masterpiece with an open ending depicted with virtu osity. While it has attracted much discussion from different perspectives, one particular aspect remains to be further explored. A careful examination of this story will enable the readers to discover a certain level of language"deviance", which in fact serves the special purpose of foregrounding. By referring to the"foregrounding theory"and applying Halliday's concept of"motivated prominence"in the linguistic analysis of the story, this paper attempts to draw special attention to such language"deviance"and reveal the hidden messages. By doing so, the readers are expected to acquire a better understanding of the theme and the implica tions in this story and fully appreciate the beauty of such language"deviance"as well as Hemingway's virtuosity in language use in his writing. 展开更多

The story of Hills Like White Elephants takesplace in an unknown small railway station in northern Spain. A young couple are waiting for the express to Barcelona. The storystarts the dialogue of the novel, which is simple and easy to understand, but vividly describes the rich inner world of the protagonists.The novel with only a few thousand words vividly shows Hemingway's unique narrative style. Hemingway uses irony, symbolism,semantics level and syntax level to depict the psychological state of characters. The Foregrounding theory of stylistics is usedto analyze the theme text and the style of Hemingway from two aspects—Deviation and Over-Regularity. 展开更多

Based on the data from 3D seismic surveys,drilling,sidewall coring,thin sections,and tests,this paper analyzes Meso-Cenozoic geotectonic dynamics,buried-hill reservoir characteristics,and differential enrichment patterns of oil and gas in the buried hills,as well as case studies of typical reservoirs,to systematically discuss the conditions required for the formation of buried-hills and reservoirs and accumulations in the large oil and gas fields in deep to ultra-deep composite buried hills in the Bohai Sea..The key findings are as follows.First,deep to ultra-deep composite buried hills developed in the offshore Bohai Bay Basin primarily due to the double-episode destruction of the North China Craton in the Yanshanian and Himalayan.The Tanlu Fault's activity and the destruction of the North China Craton worked together to create the destruction center,which moved and converged episodically from the Bohai Bay Basin's margins towards the Bozhong Sag.This led to the formation of two development zones for composite buried hills and an orderly process of mountain-building within the offshore Bohai Bay Basin and subsequently two development zones for composite buried hills,i.e.the middle and inner rim zones within the Bozhong Depression.Second,under the coupling of favorable lithologies and multi-stage structures,the middle and inner rim zones are favorable for the formation of reservoirs in fluid dissolution-pore/fracture zones underlying the weathering crust.Third,Massive hydrocarbons were produced along the middle and inner rim zones during the Episode Ⅱ craton destruction,which caused overpressure.These hydrocarbons then moved to and accumulated in the composite buried hills.Excellent conditions for the accumulation of hydrocarbons are still present in the interior and lower portions of these buried hills.These results encourage a change in buried hill research to investigate composite buried hills in three dimensions.It should be noted that the multi-stage volcanic structures in the inner rim zone of the Sag and the deep to ultra-deep composite buried hill interiors in the middle rim zone are significant successor areas for further Bohai Sea exploration. 展开更多
