1、-大学英语第四册原文-第 23 页 4Unit1 The Icy Defender 1 In 1812, Napoleon Bonaparte, Emperor of the French, led his Grand Army into Russia. He was prepared for the fierce resistance of the Russian people defending their homeland. He was prepared for the long march across Russian soil to Moscow, the capital city
2、. But he was not prepared for the devastating enemy that met him in Moscow - the raw, bitter, bleak Russian winter. 2 In 1941, Adolf Hitler, leader of Nazi Germany, launched an attack against the Soviet Union, as Russia then was called. Hitlers military might was unequaled. His war machine had mowed
3、 down resistance in most of Europe. Hitler expected a short campaign but, like Napoleon before him, was taught a painful lesson. The Russian winter again came to the aid of the Soviet soldiers. Napoleons Campaign3 In the spring of 1812, Napoleon assembled an army of six hundred thousand men on the b
4、orders of Russia. The soldiers were well trained, efficient, and well equipped. This military force was called the Grand Army. Napoleon, confident of a quick victory, predicted the conquest of Russia in five weeks. 4 Shortly afterwards, Napoleons army crossed the Neman River into Russia. The quick,
5、decisive victory that Napoleon expected never happened. To his surprise, the Russians refused to stand and fight. Instead, they retreated eastward, burning their crops and homes as they went. The Grand Army followed, but its advance march soon became bogged down by slow-moving supply lines. 5 In Aug
6、ust, the French and Russian armies engaged at Smolensk, in a battle that left over ten thousand dead on each side. Yet, the Russians were again able to retreat farther into Russian territory. Napoleon had won no decisive victory. He was now faced with a crucial decision. Should he continue to pursue
7、 the Russian army? Or should he keep his army in Smolensk for the approaching winter? 6 Napoleon took the gamble of pressing on to Moscow, 448 kilometers away. On September 7, 1812, the French and Russian armies met in fierce battle at Borodino, 112 kilometers west of Moscow. By nightfall, thirty th
8、ousand French and forty-four thousand Russians lay dead or wounded on the battlefield. 7 Again, the Russian army retreated to safety. Napoleon had a clear path to Moscow, but the occupation of the city became an empty victory. The Russians fled their capital. Soon after the French arrived, a raging
9、fire destroyed two-thirds of the city. Napoleon offered a truce to Alexander I, but the Russian czar knew he could bide his time: We shall let the Russian winter fight the war for us. 8 Napoleon soon realized he could not feed, clothe, and quarter his army in Moscow during the winter. In October 181
10、2, he ordered his Grand Army to retreat from Moscow. 9 The French retreat turned into a nightmare. From fields and forests, the Russians launched hit-and-run attacks on the French. A short distance from Moscow, the temperature had already dropped to minus 4 degrees Celsius. On November 3, the winter
11、s first snow came. Exhausted horses fell dead in their tracks. Cannon became stuck in the snow. Equipment had to be burned for fuel. Soldiers took ill and froze to death. The French soldiers dragged on, leaving the dead along every mile. 10 As the Russian army was gathering its strength, the French
12、had to flee Russia to avoid certain defeat. At the Berezina River, the Russians nearly trapped the retreating French by burning the bridges over the swollen river. But Napoleon, by a stroke of luck, was able to build two new bridges. Thousands of French soldiers escaped, but at the cost of fifty tho
13、usand dead. Once across the Berezina, the tattered survivors limped toward Vilna. 11 Of the six hundred thousand soldiers Napoleon had led into Russia, less than one hundred thousand came back. The weakened French army continued its retreat westward across Europe. Soon, Britain, Austria, Russia, and
14、 Prussia formed a powerful alliance and attacked these stragglers. In March 1814, Paris was captured. Napoleon abdicated and went into exile, his empire at an end. Hitlers Invasion12 By early 1941, Adolf Hitler, leader of Nazi Germany, had seized control of most of Europe. To the east of Hitlers Ger
15、man empire was the Soviet Union. On June 22, 1941, without a declaration of war, Hitler began an invasion of the Soviet Union that was the largest military land campaign in history. Confident of a quick victory, Hitler expected the campaign to last no longer than three months. He planned to use the
16、blitzkrieg, or lightning war, tactics that had defeated the rest of Europe. The invasion had three broad thrusts: against Leningrad and Moscow and through the Ukraine. 13 Caught off guard by the invasion, Soviet leader Joseph Stalin instructed the Russian people to scorch the earth in front of the G
17、erman invaders. Farms and factories were burned, destroyed, or rendered useless. During the first ten weeks of the invasion, the Germans pushed the front eastward, and the Russians suffered more than a million casualties. 14 In the north, the Germans closed in on Leningrad. Despite great suffering,
18、however, the people of Leningrad refused to surrender. As the battle of Leningrad dragged on into winter, the citys situation became desperate. As food ran out, people died from hunger and disease. By the middle of the winter of 1941-1942, nearly four thousand people starved to death every day. Clos
19、e to one million people died as a result of the siege. 15 In the center of Russia, Hitlers goal was the capture of Moscow. Because the Germans had anticipated a quick victory, they had made no plans for winter supplies. October arrived with heavy rains. General Mud slowed down the movement of the Ge
20、rmans lightning attack. 16 As Hitlers armies drew closer and closer to Moscow, an early, severe winter settled over the Soviet Union, the harshest in years. Temperatures dropped to minus 48 degrees Celsius. Heavy snows fell. The German soldiers, completely unprepared for the Russian winter, froze in
21、 their light summer uniforms. The German tanks lay buried in the heavy snowbanks. The Russian winter brought the German offensive to a halt. 17 By the summer of 1942, Hitler had launched two new offensives. In the south, the Germans captured Sevastopol. Hitler then pushed east to Stalingrad, a great
22、 industrial city that stretched for 48 kilometers along the Volga River. Despite great suffering, Soviet defenders refused to give up Stalingrad. 18 In November 1942, the Russians launched a counterattack. With little or no shelter from the winter cold in and around Stalingrad, German troops were fu
23、rther weakened by a lack of food and supplies. Not until January 1943 did the Germans give up their siege. Of the three hundred thousand Germans attacking Stalingrad, only ninety thousand starving soldiers were left. The loss of the battle for Stalingrad finally turned the tide against Hitler. The G
24、erman victories were over, thanks in part to the Russian winter. 19 During 1943 and 1944, the Soviet armies pushed the German front back toward the west. In the north, the Red Army broke the three-year siege of Leningrad with a surprise attack on January 15, 1944. Within two weeks, the heroic surviv
25、ors of Leningrad saw their invaders depart. By March 1944, the Ukraine farming region was again in Soviet hands. On May 9, 1944, Sevastopol was liberated from the Germans. The Russians were now heading for Berlin. 20 For Hitler, the invasion of the Soviet Union had turned into a military disaster. F
26、or the Russian people, it brought unspeakable suffering. The total Soviet dead in World War II reached almost 23 million. Russias Icy Defender21 The elements of nature must be reckoned with in any military campaign. Napoleon and Hitler both underestimated the severity of the Russian winter. Snow, ic
27、e, and freezing temperatures took their toll on both invading armies. For the Russian people, the winter was an icy defender. 4Unit2 SMART CARS1. Even the automobile industry,which has remained largely unchanged for the last seventy years,is about to feel the effects of the computer revolution.2. Th
28、e automobile industry ranks as among the most lucrative and powerful industries of the twentieth century.There are presently 500 million cars on earth,or one car for every ten people.Sales of the automobile industry stand at about a trillion dollars,making it the worlds biggest manufacturing industr
29、y.3. The car,and the roads it travesl on,will be revolutionized in the twentyfirst centy.The key to tomorrows smart carswill be sensors.Well see vehivles and roads that see and hear and feel and smell and talk and act,predicts Bill Spreitzer,technical director of General Motors Corporations ITS prog
30、ram,which is designing the smart car and road of the future.4. Approximately 40,000 people are killed each year in the United States in traffic accidents is so vast that we dont even bother to mention them in the newspapers anymore.Fully half of these fatalities come from drunk drivers,and many othe
31、rs from carelessness.A smart car could eliminate most of these car accidents.It can sense if a driver is drunk via electronic sensors that can pick up alcohol vapor in the air,and refuse to start up the engine.The car could also alert the police and provide its precise location if it is stolen.5. Sm
32、art cars have already been built which can monitor ones driving and the driving conditions nearby.Small radars hidden in the bumpers can scan for nearby cars.Should you make a serious driving mistake(e.g.,change lanes when there is a car in yourFblind spot)the computer would sound an immediate warni
33、ng.6. At the MIT Media Lab,a prototype is already being built which will determine how sleepy you are as you drive,which is especially important for long-distance truck drivers.The monotonous,almost hypnotic process of staring at the center diveder for long hours is a grossly underestimated,lifethre
34、atening hazard.To eliminate this,a tiny camera hidden in the dashboard can be trained on a drivers face and eyes.If the drivers eyelids close for a certain length of time and his or her driving becomes erratic,a computer in the dashboard could alert the driver.7. Two of the most frustrating things a
35、bout driving a car are getting lost and getting stuck in traffic.While the computer revolution is unlikely to cure these problems,it will have a positive impact.Sensors in your car tuned to radio signals from orbiting satellites can locate your car precisely at any moment and warn of traffic jams.We
36、 already have twenty-four Navstar satellites orbiting the earth,making up what is called the Global Positioning System.They make it possible to determine your location on the earth to within about a hundred feet.At any given time,there are several GPS satellites orbiting overhead at a distance of ab
37、out 11,000 miles.Each satellite contains fouratomic clocks,which vibrate at a precise frequency,according to the laws of the quantum theory.8. As a satellite passes overhead,it sends out a radio signal that can be detected by a receiver in a cars computer.The cars computer can then calculate how far
38、 the satellite is by measuring how long it took for the signal to arrive.Since the speed of light is well known,any delay in receiving the satellites signal can be converted into a distance.9. In Japan there are already over a million cars with some type of navigational capability.(Some of them loca
39、ste a cars position by correlating the rotations in the steering wheel to its position on a map.)10. With the price of microchips dropping so drastically,future applications of GPS are virtually limitless.The commercial industry is poised to explode,says Randy Hoffman of Magellan Systems Corp.,which
40、 manufactures navigational systems.Blind individuals coule use GPS sensors in walking sticks,airplanes could land by remote control,hikers will be able to locate their position in the woods-the list of potential uses is endless.11. GPS is actually but part of a larger movement,calledtelematics,which
41、 will eventually attempt to put smart cars on smart highways.Prototypes of such highways already exist in Europe,and experiments are being made in California to mount computer chips,sensors,and radio transmitters on highways to alert cars to traffic jams and obstructions.12. On an eight-mile stretch
42、 of Interstate 15 ten miles north of San Diego,traffic engineers are installing an MIT-designed system which will introduce the automated driver.The plan calls for computers,aided by thousands of three-inch magnetic spikes buried in the highway,to take complete control of the driving of cars on heav
43、ily trafficked roads.Cars will be bunched into groups of ten to twelve vehicles,only six feet apart,traveling in unison,and controlled by computer.13. Promoters of this computerized highway have great hopes for its future.By 2010,telematics may well be incorporated into one of the major highways in
44、the United States.If successful,by 2020,as the price of microchips drops to below a penny piece,telematics could be adopted in thousands of miles of highways in the United States.This could prove to be an environmental boon as well,saving fuel,reducing traffic jams,decreasing air pollution,and servi
45、ng as an alternative to highway expansion. 4Unit3 Get the Job You Want 1 I run a manufacturing company with about 350 employees, and I often do the interviewing and hiring myself. I like talking to potential salespeople, because theyre our link to customers. 2 When a recent college graduate came int
46、o my office not too long ago looking for a sales job, I asked him what he had done to prepare for the interview. He said hed read something about us somewhere. 3 Had he called anyone at Mackay Envelope Corporation to find out more about us? No. Had he called our suppliers? Our customers? No. 4 Had h
47、e checked with his university to see if there were any graduates working at Mackay whom he could interview? Had he asked any friends to grill him in a mock interview? Did he go to the library to find newspaper clippings on us? 5 Did he write a letter beforehand to tell us about himself, what he was
48、doing to prepare for the interview and why hed be right for the job? Was he planning to follow up the interview with another letter indicating his eagerness to join us? Would the letter be in our hands within 24 hours of the meeting, possibly even hand-delivered? 6 The answer to every question was the same: no. That left me with only one other question: How well prepared would this person be if he were to call on a prospective customer for us? I already knew the answer. 7 As I see it, there are four keys to getting
