Mwd.S Historically, humans get serious about avoidingdisasters only after one has just struck them. __1__ that logic, 2006 shouldhave been a breakthrough year for rational behavior.

And they are made __4__ worse by our willful blindnessto risk as much as our __5__ to work together before everything goes to hell.
oeG?2!Zh Granted, someamount of delusion(

In A.D. 63, Pompeii was seriouslydamaged by an earthquake, and the locals immediately went to work __7__, in thesame spot-until they were buried altogether by a volcano eruption 16 yearslater.

Weknow more than we __10__ did about the dangers we face. But it turns __11__that in times of crisis, our greatest enemy is __12__ the storm, the quake orthe __13__ itself.

#'h(o/hz&& According to BT’sfuturologist, Ian Pearson, these are among the developments scheduled for thefirst few decades of the new millennium(a period of 1
,000 years), whensupercomputers will dramatically accelerate progress in all areas of life.
yg@}j Pearson has __1__together to work of hundreds of researchers around the world to produce a __2__millennium technology calendar that gives the latest dates when we can expecthundreds of key __3__ and discoveries to take place. Some of the biggestdevelopments will be in medicine, including an __4__ life expectancy and dozensof artificial organs __5__ into use between now and 2040.
fuA8jx Pearson also__6__ a breakthrough in computer human links. "By linking __7__ to ournervous system, computers could pick up __8__ we feel and, hopefully, simulate__9__ too so that we can start to __10__ full sensory environments, rather likethe holidays in Total Recall or the Star Trek holodeck," he says.
kpO+ But that, Pearsonpoints __11__, is only the start of man-machine __12__:"It will be thebeginning of the long process of integration that will __13__ lead to a fullyelectronic human before the end of the next century."__14__ his research,Pearson is able to put dates to most of the breakthroughs that can bepredicted. However, there are still no __15__ for when faster-than-light travelwill be __16__, or when human cloning will be perfected, or when time travelwill be possible.
Dlu]4n[LB Buthe does __17__ social problems as a result of technological advances. A boom inneighborhood surveillance cameras will, for example, __18__ problems in 2010,while the arrival of synthetic __19__ robots will mean people may not be ableto __20__ between their human friends and the droids. And home appliances willalso become so smart that controlling and operating them will result in thebreakout of a new psychological disorder-kitchen rage.

vFwZ Practically all people (21) a desire to predict their future (22) .People seem inclined to (23) this task using causal reasoning. First, wegenerally (24) that future circumstances are (25) caused or conditioned bypresent (26) . We learn that getting an education will (27) how much money weearn later in life and that swimming beyond the reef may bring an unhappy (28)with a shark.
qP0_#l&
Second,people also learn that such (29) of cause and effect are probabilistic innature. That is, the effects occur more often when the causes occur than whenthe causes are (30) -but not always. (31), students learn that studying hard(32) good grades in most instances, but not every time. Science makes theseconcepts of causality and probability more explicit and (33) techniques fordealing (34) them more rigorously than does causal human inquiry. It sharpensthe skills we already have by making us more conscious, rigorous, and explicitin our inquiries.

KG In looking atordinary human inquiry, we need to (35) between prediction and understanding.Often, we can make predictions without understanding. And often, even if wedon’t understand why, we are willing to act (36) the basis of a demonstratedpredictive ability.
P>t[35/1 Whateverthe primitive drives or instincts that (37) human beings, satisfying themdepends heavily on the ability to predict future circumstances. The attempt topredict is often played in a (38) of knowledge and understanding. If you canunderstand why things are related to one another, why certain regular patterns(39), you can predict better than if you simply observe and remember thosepatterns. Thus, human inquiry aims (40) answering both “what” and “why”questions, and we pursue these goals by observing and figuring out.

字左右的短文,测试考生的七种能力,语篇的理解能力和是否把握作者的推理过程。熟悉议论文、记叙文、说明文和应用文文章体裁特点、篇章结构,有利于分清主次,抓住重点,判断出考题中的正确选项。 4\?I4|{pC 议论文的特点是对客观事物进行分析和评论,重点放在论点及论证方面,主题往往比较明确,通常开头点明主题,表明作者的观点和态度,其后段落围绕主题展开。一篇短文如果有若干个论点,要弄清楚哪个是主论点、哪个是次论点或分论点以及主次论点之间的论证关系。议论文常见的推理方法有:归纳法:由个别到一般:先设前提,通过例证归纳出结论。演绎法:由—
般到个别:先提出—
般性的论断,再逐步提出支持该论断的证据,最后推出结论。阅读议论文的关键是要抓住作者的结论和观点,以及作者对具他观点的态度。 *4^!e/ 说明文是对客观事物的性质、特征、形状、构成、功能等进行介绍和解说。完全客观地描述,不带有个人感情色彩。说明文常见的几种写作方法有:下定义、举例证、析因果、分类别、作对比等。阅读说明文体裁的文章要把握短文的中心,掌握作者是从何角度、采用什么方法加以说明的,注意事实和数据。 IjDG 短文一般有以下几种结构模式: x]k^JPX 1

o|l)oc6{ The molecules of carbon dioxide in the Earth's atmosphere affect theheat balance of the Earth by acting as a one-way screen. Although thesemolecules allow radiation at visible wavelengths, where most of the energy ofsunlight is concentrated, to pass through, they absorb some of thelonger-wavelength, infrared emissions radiated from the Earth's surface,radiation that would otherwise be transmitted back into space. For the Earth tomaintain a constant aver-age temperature, such emissions from the planet must balanceincoming solar radiation. If there were no car-bon dioxide in the atmosphere,heat would escape from the Earth much more easily. The surface temperaturewould be so much lower that the oceans might be a solid mass of ice.
Ps<)?q6( Today, however, the potential problem is too much carbon dioxide.The burning of fossil fuels and the clearing of forests have increasedatmospheric carbon dioxide by about 15 percent in the last hundred years, andwe continue to add carbon dioxide to the atmosphere. Could the increase incarbon dioxide cause a global rise in average temperature, and could such arise have serious consequences for human society?
xHykU;p@ Mathematical models that allow us to calculate the rise intemperature as a function of the increase indicate that the answer is probablyyes. Under present conditions a temperature-of--18
℃can be observed at an altitude of 5 to 6 kilometers above theEarth. Below this altitude (called the radiating level), the temperatureincreases by about 6
℃ perkilometer approaching the Earth's surface, where the average temperature isabout 15
℃. An increase in the amount of carbondioxide means that there are more molecules of carbon dioxide to absorbinfrared radiation. As the capacity of the atmosphere to absorb infraredradiation increases, the radiating level and the temperature of the surfacemust rise. One mathematical model predicts that doubling the atmospheric carbondioxide would raise the global mean surface temperature by 2.5
℃.This model assumes that the atmosphere's relative humidity remains constant andthe temperature decreases with altitude at a rate of 6.5
℃per kilometer. The assumption of constant relative humidity is important,because water vapor in the atmosphere is another efficient absorber ofradiation at infrared wavelengths. Because warm air can hold more moisture thancool air, the relative humidity will be constant only if the amount of watervapor in the atmosphere increases as the temperature rises. Therefore, moreinfrared radiation would be absorbed and reradiated back to the Earth'ssurface. The resultant warming at the surface could be expected to melt snowand ice, reducing the Earth's reflectivity. More solar radiation would then beabsorbed, leading to a further increase in temperature.
