　　Notable as important nineteenth-century novels by women, Mary Shelley’s Frankenstein and Emily Bronte’s Wuthering Heights treat women very differently. Shelley produced a “masculine” text in which the fates of subordinate female characters seem entirely dependent on the actions of male heroes or anti-heroes (anti-hero: n.平凡的主角). Bronte produced a more realistic narrative, portraying a world where men battle for (battle for: v.为...斗争) the favors of apparently high-spirited, independent women. Nevertheless, these two novels are alike in several crucial ways. Many readers are convinced that the compelling mysteries of each plot conceal elaborate structures of allusion and fierce, though shadowy, moral ambitions that seem to indicate metaphysical intentions, though forts by critics to articulate these intentions have generated much controversy. Both novelists use a storytelling method that emphasizes ironic disjunctions between different perspectives on the same events as well as ironic tensions that inhere in the relationship between surface drama and concealed authorial intention, a method I call an evidentiary narrative technique.

　　(C) Telling a story in a way that both directs attention to the incongruities among the points of view of several characters and hints that the plot has a significance other than that suggested by its mere events

　　(D) Telling a story as a mystery in which the reader must deduce, from the conflicting evidence presented by several narrators, the moral and philosophical significance of character and event

　　Climatic conditions are delicately adjusted to the composition of the Earth’s atmosphere. If there were a change in the atmosphere—for example, in the relative proportions of atmospheric gases—the climate would probably change also. A slight increase in water vapor, for instance, would increase the heat-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the amount of solar energy reaching the Earth’s surface.

　　The level of carbon dioxide, CO2, in the atmosphere has an important fect on climatic change. Most of the Earth’s incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation, which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse fect, can result in an increase in the surface temperature of a planet. An extreme example of the fect is shown by Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430℃. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2 concentration would lead only to a reduction in global temperatures of 3℃.

　　If, because of an increase in forest fires or volcanic activity, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2 would probably increase. As a consequence, plants would use more and more CO2. Eventually CO2 levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increases and decreases of a set magnitude.

　　Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature increase of at least 1℃. But a supposed global temperature rise of 1℃ may in reality be only several regional temperature increases, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example the Southern Hemisphere oceanic zone, may be experiencing an equivalent temperature decrease that is unrecognized because of the shortage of meteorological recording stations.

　　21. The passage supplies information for answering which of the following questions?

　　(A) Why are projections of the fects of changes in water vapor levels on the climate so inaccurate?

　　(B) What are the steps in the process that takes place as CO2 absorbs long-wavelength radiation?

　　(C) How might our understanding of the greenhouse fect be improved if the burning of fossil fuels were decreased?

　　(D) What might cause a series of regular increases and decreases in the amount of CO2 in the atmosphere?

　　22. The author is primarily concerned with

　　(A) explaining the fects that the burning of fossil fuels might have on climate

　　(B) illustrating the fects of CO2 on atmospheric radiation

　　(C) discussing fects that changes in the CO2 level in the atmosphere might have on climate

　　(D) challenging hypotheses about the fects of water vapor and CO2 on climate

　　(E) ruting hypotheses by climatologists about the causes of global temperature fluctuations

　　23. The passage suggests that a large decrease in the amount of CO2 in the atmosphere would result in

　　(A) at least a slight decrease in global temperatures

　　(B) at the most a slight increase in short-wavelength radiation reaching the Earth

　　(C) a slight long-term increase in global temperatures

　　(D) a large long-term increase in the amount of volcanic activity

　　(C) show the extent to which Earth’s atmosphere differs from that of Venus

　　(D) support the contention that as water vapor increase, the amount of CO2 increases

　　(E) support the argument that the CO2 level in the atmosphere has a significant fect on climate

　　25. The passage suggests that if there were a slight global warming at the present time, it would be

　　(A) easy to measure the exact increase in temperature because of the abundance of temperature recording stations throughout the world

　　(B) difficult to measure the increase of CO2 in the atmosphere because of local variations in amounts

　　(C) easy to demonstrate the fects of the warming on the water vapor in the atmosphere

　　(D) difficult to prove that the warming was caused by the burning of fossil fuels

　　(E) easy to prove that the warming was caused by an increase of cloud cover

　　26. The discussion of climate in the passage suggests which of the following conclusion?

　　I. Climate is not perfectly stable, and slight regional temperature variations can be considered a normal feature of the environment.
