Technology{{U}} (51) {{/U}}tactics, sociology, and the development of weaponry (武器). It also causes the changes in battles. Then what are the new characteristics of modern battles{{U}} (52) {{/U}}by the application of high technologies? High-tech warfare naturally includes high technology. In modern battles, a single kind of weapon can hardly be{{U}} (53) {{/U}}. Various weaponry, such as intelligence detection and information processing, should{{U}} (54) {{/U}}well with each other. Aerial (航空的) weaponry becomes the main force in battles in the sky. Precision homing (精确自导) weaponry like cruise missiles and Missiles{{U}} (55) {{/U}}satellite homing systems becomes the main attack weapons. Battle control systems play a dominant role. Various weapons and logistics (后勤) systems are{{U}} (56) {{/U}}into a comprehensive framework, centrally representing the modern high-tech weaponry. Depending on various{{U}} (57) {{/U}}equipment and means in electronic warfare, our army will not be passively beaten.{{U}} (58) {{/U}}the battlefield, high-tech warfare has created a type of non-linear (非线性的) chaos. Because of the use of long-range precision weaponry, the opposite parties in warfare can't "touch" or "see" each other, and distance is no longer the decisive factor affecting the{{U}} (59) {{/U}}of battles. It is hard to clearly define the lines between the frontier and the rear, as well as attack and defense. The traditional three-dimensional air-sea battlefield will be{{U}} (60) {{/U}}by the multi-dimensional battlefield composed of air, sea, magnetic, electrical and information battlefields. No large-scale movements can be conducted{{U}} (61) {{/U}}. Because modern weaponry systems are closely related to chains of demand and communication and electronic technology, the parties{{U}} (62) {{/U}}have to pay attention to the usufruct (使用权) and control of electromagnetic frequency spectrum. So electronic warfare becomes{{U}} (63) {{/U}}important and the necessary guarantee of victory. Whatever{{U}} (64) {{/U}}warfare goes to and whatever cloak (伪装) it wears, it always violates peace and brings the world bloodshed (流血). Most people think of high technology as a{{U}} (65) {{/U}}to enhance their lives, and they don't wish it to be used to destroy lives.

单选题Obesity Causes Global Warming The list of ills attributable to obesity keeps growing: Last week, obese people were accused of causing global warming. This conclusion comes from Sheldon Jacobson of the University of Illinois, U. S. , and a doctoral student, Laura McLay. Their study calculates how much extra gasoline is needed to haul fat Americans around. The answer, they say, is a billion gallons of gas per year. It means an extra 11 million tons of carbon dioxide. There has been calls for taxes on junk food in recent years. U. S. economist Martin Schmidt suggests a tax on fast food delivered to people's cars. "We tax cigarettes partly because of their health cost," Schmidt said. "Similarly, leading a lazy lifestyle will end up costing taxpayers more. " U. S. political scientist Eric Oliver said his first instinct was to laugh at these gas and fast food arguments. But such claims are getting attention. At the U. S. Obesity Society's annual meeting, one person correlated obesity with car accident deaths, and another correlated obesity with suicides. No one asked whether there was really a cause-and-effect relationship. "The funny thing was that everyone took it seriously," Oliver said. In a 1960s study, children were shown drawings of children with disabilities and without them, a drawing of an obese child. They were asked which they would want for a friend? The obese child was picked last. Three researchers recently repeated the study using college students. Once again, ahnost no one, not even obese people, liked the obese person. "Obesity was stigmatized," the researchers said. But, researchers say, getting thin is not like quitting smoking. People struggle to stop smoking, and, in the end, many succeed. Obesity is different. But, not because obese people don't care. Science has shown that they have limited personal control over their weight.

单选题{{B}}第三篇{{/B}} {{B}}The Rising Oil Price{{/B}} Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time? The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the dame time as winter grips the northern hemisphere, could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economics are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economics now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $ 22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25%~0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted— have become more energy-intensive, and so could be more seriously squeezed. One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The Economist’s commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%.
