单选题{{B}}Passage 1{{/B}} The climate of Earth is changing. Climatologists are confident that over the past century, the global average surface temperature has increased by about half a degree Celsius. This warming is thought to be at least partly the result of human activities, such as the burning of fossil fuels and the clearing of forests for agriculture. As the global population grows and national economies expand, the global average temperature is expected to continue increasing by an additional 1.0℃ to 3.5℃ by the year 2100. Climate change is one of the most important environmental issues facing human- kind. Understanding the potential impacts of climate change for natural ecosystems is essential if we are going to manage our environment to minimize the negative consequences of climate change and maximize the opportunities that it may offer. Because natural ecosystems are complex, nonlinear systems, it follows that their responses to climate change are likely to be complex. Climate change may affect natural ecosystems m a variety of ways. In the short term. climate change can alter the mix of plant species in land ecosystems such as grasslands. In the long term, climate change has the potential to dramatically alter the geo- graphic distribution of major vegetation types savannas, forests, and climate change can also potentially alter global ecosystem processes, including the cycling of carbon, nitrogen, phosphorus, and sulfur. Moreover. changes in these ecosystem processes can affect and be affected by changes in the plant species of the ecosystem and vegetation type. All of the climate change-induced alterations of natural ecosystems affect the services, that these ecosystems provide to humans. The global average surface temperature increase of half a degree Celsius observed over the past century has been in part due to differential changes in daily maximum and minimum temperatures, resulting in a narrowing of the diurnal temperature range. Decreases in the diurnal temperature range were first identified in the United States, where large-area trends showed that maximum temperatures have remained constant or increased only slightly, whereas minimum temperatures have increased at a faster rate. In this issue, Al-ward et al. report on the different sensitivities of rangeland plants to minimum temperature increases.

单选题{{B}}阅读理解四{{/B}} {{B}}Questions 16 to 20 are based on the following passage.{{/B}} Religion consists of conscious ideas, hopes, enthusiasms, and objects of worship; it operates by grace and flourishes by prayer. Reason, on the other hand, is a mere principle or potential order, on which indeed we may come to reflect but which exists in us ideally only, without variation or stress of any kind. We conform or do not conform to it; it does not urge or chide us, not call for any emotions on our part other than those naturally aroused by the various objects which it unfolds in their true nature and proportion. Rationality is nothing but a form, an ideal constitution which experience may more or less embody. Religion is a part of experience itself, a mass of sentiments and ideas. The one is an inviolate principle, the other a changing and struggling force. And yet this struggling and changing force of religion seems to direct man toward something eternal. It seems to make for an ultimate harmony within the, soul and for an ultimate harmony between the soul and all that the soul depends upon. Religion, in its intent, is a more conscious and direct pursuit of the Life of Reason than is society, science, or art, for these approach and fill out the ideal life tentatively and piecemeal, hardly regarding the foal or caring for the ultimate justification of the instinctive aims. Nevertheless, we must confess that this religious pursuit of the Life of Reason has been singularly abortive. Those within the pale of each religion may prevail upon themselves, to express satisfaction with its results, thanks to a fond partiality in reading the past and generous draughts of hope for the future; but any one regarding the various religions at once and comparing their achievements with what reason requires, must feel how terrible is the disappointment which they have one and all prepared for mankind. To confuse intelligence and dislocate sentiment by gratuitous fictions is a short-sighted way of pursuing happiness. Thus religion too often debauches the morality it comes to sanction and impedes the science it ought to fulfill. Religion pursues rationality through the imagination. When it explains events or assigns causes, it is an imaginative substitute for science. When it gives precepts, insinuates ideals, or remoulds aspiration, it is an imaginative substitute for wisdom—I mean for the deliberate and impartial pursuit of all food. The condition and the aims of life are both represented in religion poetically, but this poetry tends to arrogate to itself literal truth and moral authority, neither of which it possesses. Hence the depth and importance of religion becomes intelligible no less than its contradictions and practical disasters. Its object is the same as that of reason, but its method is to proceed by intuition and by unchecked poetical conceits.
