Then, most Americans had little interest in 1,500,000 square kilometers "of icebergs and polar bears" — beyond Canada's western borders, far from the settled areas of the United States. In those sections of the state which lie above the Arctic Circle, Alaska still is a land of icebergs and polar bears. Ice masses lie buried in the earth, which is permanently frozen to a depth of 90 or more meters region. From early May until early August, the midnight sun never sets on this flat, treeless region, but the sun can not melt the icy soil more than two-thirds of a meter down. Alaska is America's largest state, but only about 325,000 people live there according to estimates, 800,000 hectares of its land area are fit for plowing but only about 640,000 hectares being cultivated. Arctic Alaska has been the home of Eskimos for countless centuries. It is believed that the Eskimos moved there from Mongolia or Siberia, probably crossing Bering Strait, named for Vitus Bering, the Danish sea captain who discovered Alaska on his voyage for Russia in 1741.The Eskimos are the state's earliest known inhabitants Russian fur traders established settlements but, by the time Alaska was sold to the United States, most of the traders had departed. In 1896 gold was discovered near the Klondike River in Canada just across the Alaskan border. Thousands of Americans rushed to the region on their way to .Klondike; some never returned. Alaska was never completely cut off again, although even today transportation is a major problem. There are only two motor routes from the US mainland, and within the state, every town has its own airfield. Planes fly passengers, mail and freight to the most distant villages. The gold that changed life so suddenly for Alaska was soon ended, and although many stories about mining camps have become part of'American literature, the gold from Alaskan earth contributed less to economic progress than the fish from Alaskan waters. The fish from Alaskan waters. The fish caught in a single year range in value from $ 80 million to $ 90 million. Fur-beating animals are plentiful in the forests and streams, and valuable fur seals inhabit the waters. Afterfishing, the state's chief industry is lumber and the production of wood pulp. In recent years, Alaska's single most important resource has become oil. The state also has large deposits of coal, copper, gold and other minerals.

Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results from landslides or major fires which are initiated by the quake. These are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from 0 upward. The highest scale recorded to date is 8.9. Major damage generally occurs from quakes ranging upward from 6.0. The actual cause of the quake itself is the breaking of rocks at or below the earth's surface. This is produced by pressure which scientists b~lieve may be due to a number of reasons, two of which are the expansion and contraction of the earth's crust and continental drift. In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Special instruments are used to help people record, for example, shaking of the earth. Scientists are trying to find methods that will enable them to indicate the exact time, location and size of an earthquake. Certain phenomena have been observed which are believed to be the signs of imminent earthquakes. These include strange behaviors of some animals, the changes in the content of mineral water, etc. The magnetic properties of rocks may also display special pattern before earthquakes happen.

For example, if workers arrived at 6 a m, the cones could move from the side of the highway to block off the lane at that time.{{U}} (2) {{/U}}"It just seems like a very good application for robots," Farritor said. "The robotic cones would also help remove people from hazardous jobs on the highway putting barrels and cones into place," Farritor said in a report on his creation.{{U}} (3) {{/U}}This fund allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard.

"Normally there's a kind of robbery, black base to them.{{U}} (4) {{/U}}" Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they might need. The robots could come in handy following a slow-moving maintenance operation, like painting a stripe on a road or moving asphalt, where now the barrels have to be picked up and moved as the operation proceeds. "That way you don't have to block offa 10-mile strip for the operation," Fardtor said. While prototypes have been made, they are not in use anywhere.

Generally, what makes a jump impressive is its hang time, the amount of time a dancer spends in the air. The quest for greater hang time is a battle against gravity, the constant{{U}} (1) {{/U}}pull of Earth, said Laws. To leave the ground at all, a dancer has to use leg muscles to create an upward push that is greater than Earth's downward pull. But the final{{U}} (2) {{/U}}of any jump depends on just one thing: the upward speed of the body just as the dancer leaves the ground. Strengthening muscles so they can push harder is one obvious{{U}} (3) {{/U}}to achieve higher jumps and increase hang time. But ballet dancers also use a simple trick to gain the illusion of staying in the air longer without actually doing so. In a huge sideways jump called a grand jete, a{{U}} (4) {{/U}}ballet dancer seems to float for an impossible length of time. Of course, a dancer can't really hang in the air. The laws of physics decree that during any jump, a dancer's center of gravity must follow a parabola. A parabola is the same{{U}} (5) {{/U}}path a ball takes when you throw it into the air. So how do dancers make it look like they're hanging in the air? A dancer{{U}} (6) {{/U}}the illusion of floating in the air by lifting her legs and arms as she approaches the peak of the jump. The{{U}} (7) {{/U}}of her body — her torso and her head — respond by sinking a bit. If her timing is just right, she'll seem to float sideways, instead of rising and falling. The effect is not only beautiful; it{{U}} (8) {{/U}}makes the jump seem bigger by "stretching out" the peak. Of course, what goes up must come down. During a typical grand jete, a dancer's center of gravity rises 2 feet{{U}} (9) {{/U}}the ground. Pulled by gravity from such a height, the dancer's body falls very fast —roughly 3.4 meters per second —by the time it reaches the floor. As it falls, the body carries with it momentum. Momentum is the weight of the body multiplied by its{{U}} (10) {{/U}}The bigger the body is and the faster it falls, the greater its momentum. The only way a dancer can stop dropping through the air is by stopping the body's momentum, which requires an{{U}} (11) {{/U}}force from the ground. Landing can be very jarring to a dancer and can{{U}} (12) {{/U}}injuries. The dancer call ease the landing by bending her knees and letting her aims fall, but she also gets help from an unexpected source: the floor. Wooden dance floors are designed to act{{U}} (13) {{/U}}shock absorbers. They are spring'y and can recoil as much as an inch under extreme pressure. That little bit of give makes a big{{U}} (14) {{/U}}Landing on a springy floor, the dancer undergoes a slower change in momentum than she would hitting a rigid floor. The give in the floor allows the decrease in momentum to happen more{{U}} (15) {{/U}}with less force and less chance of injury. jete n. (芭蕾舞中的)小跳 jarring adj.

Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891. Although it was by no means the first popular automobile.the Model T showed the world just how creative Ford was at combining technology and market. The company's assembly line alone threw America's Industrial Revolution into overdrive (高速运转). Instead of having workers put together the entire .car, Ford's friends, who were great toohnakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford's Highland Park plant was humming (嗡嗡作响) along in 1914, the world's first automatic conveyor belt could turn out a car every 93 minutes. The same year Henry Ford shocked the world with the $ 5—a day minimum wage scheme, the greatest contribution he had ever made. The average wage in the auto industry then was $ 2.34 for a 9-hour shift. Ford not only doubled that, he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn't involve all awful lot of training or education. The Wall Street Journal called the plan "an economic crime", and critics everywhere laughed at Ford. But as the wage increased later to daily $10, it proved a critical component of Ford's dream to make the automobile accessible (可及的) to all. The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn't matter — except for making it possible for more people to buy Cars.

Myers is the founder of Auburn University's Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices--an artificial nose. For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arson(纵火)investigators and food-safety inspectors. The technology that they are working on would suggest quite reasonable that, within three to five years, we'll have some workable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination. The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too, are the possibilities for abuse: Such machines could determine whether a woman is ovulating(排卵), without a physical exam--or even her knowledge, One of the traditional protectors of American liberty is that it has been impossible to search everyone. That's getting not to be the case. Artificial biosensors created at Auburn work totally differently from anything ever seen before. AromaScan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts our odors based on their electrical signatures. Myers says they expect to load a single fingernail-size chip with thousands of odor receptors (感受器), enough to create a sensor that's nearly as sensitive as a dog's nose.

Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997，research into cloning has grown rapidly．In May 1998，scientists in Massachusetts managed to create two identical calves(牛犊)using cloning technology．A mouse has also been cloned successfully， But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement：“We will have managed to clone a human being within the next two years，”he told the world． 2 Seed’S announcement provoked a lot of media attention，most of it negative．In Europe， nineteen nations have already signed an agreement banning human cloning and in the US the President announced：”We will be introducing a law to ban all human cloning and many states in the US will have passed anti-cloning laws by the end of the year．’’ 3 Many researchers are not so negative about cloning，They are worried that laws banning human cloning will threaten important research．In March，The New England Journal of Medicine called any plan to ban research on cloning humans seriously mistaken．Many researchers also believe that in spite of attempts to ban it，human cloning will have become routine by 2010 because it is impossible to stop the progress of science．4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded(轰炸)with newspaper articles，television shows and films，as well as cartoons．Suchinformation is often misleading，and makes people wonder what on earth the scientists will be doing next． 5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like．But how would it feel to be a clone among hundreds，the anti-cloners ask．Pretty cool, answer the pr-cloners(赞成克隆的人)．

阅读下面的短文，文中有15处空白，每处空白给出了4个选项，请根据短文的内容从4个选项中选择1个最佳答案。 There is no good place to have a car crash -- but some places are worse than others. In a foreign country, for instance,{{U}} (1) {{/U}}to explain via cellphone that you are upside down in a ditch when you cannot speak the local language can fatally delay the arrival of the emergency services. But an answer may be at hand. Researchers funded by the European Commission are beginning tests of a system called E-merge that{{U}} (2) {{/U}}senses when a car has crashed and sends a text message telling emergency services in the local language that the accident has taken place. The system was{{U}} (3) {{/U}}by ERTICO, a transport research organization based in Brussels, Belgium. Cars are fitted with a cellphone-sized device attached{{U}} (4) {{/U}}the underside of the dashboard which is activated by the same sensor that triggers the airbag in a crash. The device{{U}} (5) {{/U}}a cellphone circuit, a GPS positioning unit and a microphone and loudspeaker. It registers the severity of the crash by{{U}} (6) {{/U}}the deceleration data from the airbag's sensor. Using GPS information, it works out which ootmtry the Car is in, and from this it determines{{U}} (7) {{/U}}which language to compose an alert message detailing precise location of the accident. The device then automatically makes a call to the local emergency services{{U}} (8) {{/U}}. If the car's occupants are conscious, they can communicate with the operator{{U}} (9) {{/U}}the speaker and microphone. E-merge also transmits the vehicles make, model, color and license number, and its heading when it crashed, which in rum indicates on which side of a multi-lane highway it ended up.' This{{U}} (10) {{/U}}the emergency services find the vehicle as soon as they arrive on the scene. "We can waste a large{{U}} (11) {{/U}}time searching for an incident," says Jim Hammond, a (an){{U}} (12) {{/U}}in vehicle technology at the Association of Chief Police Officers in the UK. Tests will begin soon with police car fleets in the UK. Trials have already started in Germany, Sweden, Spain, the Netherlands and Italy. In-car systems that summon the emergency services after a crash have{{U}} (13) {{/U}}been fitted in some premium cars. ERTICO says that{{U}} (14) {{/U}}EU states "are willing to fund the necessary infrastructure, E-merge could be working by 2008. A study by French car maker Renault concluded that the system could save up to 6000 of the 40, 000 lives lost each year on Europe's roads, and prevent a similar number of serious injuries. The Renault study estimates that fitting E-merge to every car in Europe would eventually save around 150 billion per{{U}} (15) {{/U}}in terms of reduced costs to health services and insurance companies, and fewer lost working days. cellphone n.移动电话，手机 underside n. 下侧；底面 dashboard n.
