问答题Please read the following article in Chinese carefully, and then write a summary of 200 words in English on the ANSWER SHEET. Make sure that you cover all the major points of the article. 科学家说，在第一批艾滋病例被发现以后的20年里，他们对这种病毒性疾病的了解已超过其他任何一种病毒性疾病。但是，联合国艾滋病规划署的负责人彼得?皮奥和国际艾滋病学会会长罗马的斯特凡诺?韦拉及其他一些专家都认为，全面考察那些尚未解决的问题，可能对艾滋病和其他疾病治疗的进展是一项有益的举措。 这些较广泛的重要科学问题包括： 为什么艾滋病使患者容易感染某些癌症和传染病? 一种传统的说法是，癌细胞在人体内不断繁殖，但受到健康免疫系统的控制。艾滋病的情况却不是这样。艾滋病人很容易患非何杰金氏淋巴瘤和卡波西氏肉瘤，但不易患在美国最常见的乳腺癌、结肠癌和肺癌等。这说明，受损的免疫系统(至少是艾滋病患者的免疫系统)可以抑制普通癌细胞的发展。 艾滋病病毒侵入人体后通过什么途径摧毁免疫系统? 当艾滋病病毒通过性接触传播时，病毒必须穿过组织屏障进入人体。这个过程目前尚不清楚。病毒可能直接侵入，或许由一系列不同种类的细胞带入。最终，艾滋病病毒穿过淋巴管到淋巴结和淋巴系统的其他部分。但病毒是如何摧毁人体内负责打击入侵传染体的CD一4细胞的，目前还无法确定。 艾滋病病毒是怎样破坏免疫系统的? 艾滋病病毒能杀死对付自己的免疫细胞，但艾滋病病毒携带者患艾滋病的快慢却大不相同。因此科学家提出问题：免疫系统中那些使人患艾滋病时间出现差异的因素能否被识别出来?如果能，它们能否用于制止艾滋病患者病情的恶化，甚至在最初就可能防止人们感染艾滋病病毒? 最有效的艾滋病疗法是什么? 从理论上来说，尽早治疗可以提供维护免疫功能的最佳时机。但是新药物无法彻底清除体内的艾滋病病毒，因此患者不得不终身服用这些具有危险副作用的药物，而且还可能在产生抗药性时改服别的药物。因此新的方法可能建议在免疫系统出现衰退迹象时才开始治疗。 可能研制出疫苗吗? 毫无疑问，一种有效的疫苗是控制这种瘟疫的关键。但是目前只有一种疫苗进入了全面检验的阶段，而对其会有多大的保护功能，却有着很大的争议。世界各地流行的艾滋病在遗传类型上各不相同，目前还不清楚的是，从某种艾滋病病毒获得的疫苗能否防止其他类型的艾滋病。 如果没有疫苗，能否阻止艾滋病病毒的传播? 如果没有深入集中的行为研究，仅靠宣传是无法阻止这种全球性瘟疫的。

问答题Time was when the solar system had two watery worlds. 46) Directly next door to the warm. wet, loamy Earth was the warm, wet, loamy Mars, both planets covered with oceans and running with rivers-and both possibly teeming with life. Billions of years ago, however, the low-gravity Mars had both its air and water leak away, causing the planet to become the dead, freeze-dried place it is today. That is what the prevailing thinking has been. Now, it appears that thinking may be wrong. 47) Recently, NASA released new images from the Mars Global Surveyor spacecraft that suggest water may be flowing up and streaming onto the Martian surface-dramatically increasing the likelihood that at least part of the planet is biologically alive. "If these results prove true," says Ed Weiler, associate administrator of NASA's Office of Space Science, "[they have] profound implications for the possibility of life." Finding liquid water on Mars' surface has never been easy-because it simply can't exist there. The modern-day Martian atmosphere has barely 1 percent the density of Earth's, and its average temperature hovers around-67 degrees Fahrenheit (-19 degrees Centigrade) . In an environment as harsh as this, water would either vaporize into space or simply flash-freeze in place. 48) Scientists studying Martian history have always looked for clues the planet's ancient water left behind-tracks where vanished rivers once flowed, basins where vanished seas once stood. 49) The approximately 65, 000 images the Surveyor orbiter has beamed home in the nearly three years it has been circling Mars are full of this kind of expected hydro-scarring. But some of the pictures took scientists by surprise. The older a formation is, the more likely it is to have been distorted over the eons-smoothed by periodic windstorms or gouged by the occasional incoming meteor. However, a few of the newly discovered water channels look fresh. That discovery has lead astonished researchers to conclude that these channels may have been recently formed. 50) planetologists have long assumed that if underground water was going to bubble up on Mars, it would have to be somewhere in the balmy equatorial zones: where temperatures at noon in midsummer may reach 68 degrees Fahrenheit (20 degrees Centigrade). Almost all the new channels, however, were discovered at the planet's relative extremes-north of 30 degrees north latitude and south of 30 degrees south latitude-and all were carved on the cold, shaded sides of slopes.

问答题Economics, as we know it, is the social science concerned with the production, distribution, exchange, and consumption of goods and services. Economists focus on the way in which individuals, groups, business enterprises, and governments seek to achieve efficiently any economic objective they select. (46) Other fields of study also contribute to this knowledge: Psychology and ethics try to explain how objectives are formed, history records changes in human objectives, and sociology interprets human behavior in social contexts. Standard economics can be divided into two major fields. (47) The first, price theory or microeconomics, explains how the interplay of supply and demand in competitive markets creates a multitude of individual prices, wage rates, profit margins, and rental changes. Microeconomics assumes that people behave rationally. Consumers try to spend their income in ways that give them as much pleasure as possible. As economists say, they maximize utility. For their part, entrepreneurs seek as much profit as they can extract from their operations. The second field, macroeconomics, deals with modern explanations of national income and employment. Macroeconomics dates from the book, The General Theory of Employment, Interest, and Money (1935), by the British economist John Maynard Keynes. His explanation of prosperity and depression centers on the total or aggregate demand for goods and services by consumers, business investors, and governments. (48) Because, according to Keynes, inadequate total demand increases unemployment, the indicated cure is either more investment by businesses or more spending and consequently larger budget deficits by government. Economic issues have occupied people's minds throughout the ages. (49) Aristotle and Plato in ancient Greece wrote about problems of wealth, property, and trade, both of whom were prejudiced against commerce, feeling that to live by trade was undesirable. The Romans borrowed their economic ideas from the Greeks and showed the same contempt for trade. (50) During the Middle Ages the economic ideas of the Roman Catholic church were expressed in the law of the church, which condemned the taking of interest for money loaned and regarded commerce as inferior to agriculture. Economics as a subject of modern study, distinguishable from moral philosophy and politics, dates from the work, Inquiry into the Nature and Causes of the Wealth of Nations (1776), by the Scottish philosopher and economist Adam Smith. Mercantilism and physiocracy were precursors of the classical economics of Smith and his 19th-century successors.
