1、考研英语（阅读）模拟试卷 44 及答案与解析Part ADirections: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)0 High DiveCheryl Sterns aims to go boldly where no human has ever gone before in a balloon: 40 kilometers up into the atmosphere. 41 No one has ever leapt

2、 from such a height or gone supersonic without an airplane or a spacecraft. Yet Sterns, an airline pilot, is not the only person who wants to be the first to accomplish those feats. Two other brave people, an Australian man and a Frenchman, are also planning to make similar leaps.42 First, shell cli

3、mb into a cabin hanging from a balloon the size of a football field. Then balloon will take her high into the stratosphere-the layer of Earths atmosphere 12 to 50 kilometers above the planet. “The ascent will take two and a half to three hours, “ said Sterns. “Ill be wearing a fully pressurized, tem

4、perature-controlled space suit.“At 40 kilometers, Sterns will be able to see the gentle curve of Earth and the blackness of space over head. Then shell unclip herself from the cabin and dive headfirst, like a bullet, into the atmosphere. 43For high dive, astronaut escape suits are a key to success.

5、Current pilot and astronaut escape suite are guaranteed only a maximum altitude of 21 kilometers. Del Rosso, a NASA engineer of spacesuits and life-support systems, said the suit designed for Sterns jump could serve as a model for the lethal environment of higher climbs. _44 The first hazard is oxyg

6、en-deficient air. Any person without an additional oxygen supply at 40 kilometers would die within three to five seconds. The second hazard is low atmospheric pressure. Atmospheric pressure is much lower at high altitudes than it is at sea level. The low atmospheric pressure of the upper stratospher

7、e causes the gases in body fluids to fizz out of solution like soda bubbles. 45 Other hazards include temperatures as low as -55 degrees Celsius, flying debris, and solar radiation.For Sterns to survive, her spacesuit will have to protect her from all of these hazards. “A spacesuit is like a one-per

8、son spaceship, “ Del Rosso explained. “You have to take everything you need in a package thats light enough, mobile enough, and tough enough to do the job. You cant exist without it. “A. It will handle several major hazards.B. Escape suits are tough enough to stand the atmospheric pressure of the up

9、per stratosphere.C. From there, shell take a death-defying leap back to Earth at supersonic speed.D. “In 30 seconds, Ill be going Mach (马赫) speed, “ said Sterns.E. How will Sterns make her giant jump?F. In short, blood boils.5 Virtual DriverDriving involves sharp eyes and keen ears, analyzing with a

10、 brain, and coordination between hands, feet and brain. A man has sharp eyes and keen ears, analyzes through his brain, and maintains coordination between his hands and brains. He can control a fast-moving car with different parts of his body. 41 Apparently there isnt anyone in the drivers cab, but

11、there is in fact a virtual driver. This virtual driver has eyes, brains, hands and feet too. The mincemeats on each side of the car are its eyes and are responsible for observing the road conditions ahead of it as well as the traffic to its left and right. If you open the boot, you can see the most

12、important part of the automatic driving system: a built-in computer. 42 The brain is responsible for calculating the speeds objects surrounding the car are moving at, analyzing their position on the road, choosing the right path, and giving orders to the wheel and the control system.In comparison wi

13、th the human brain, the virtual drivers best advantage is that it reacts quickly. 43 However, it takes the worlds best racecar driver at least one second to react, and this doesnt include the time he needs to take action.With its rapid reaction and accurate control, the virtual driver can reduce the

14、 accident rate on expressways considerably. In this case, is it possible for us to let it have the wheel at any time and in any place? 44 With its limited ability to recognize things, the car can now only travel on expressways.The intelligent car determines its direction by the clear lines that mark

15、 the lanes clearly and recognizes vehicles according to their regular shapes. 45 This being the case, people still have high hopes about driverless cars, and think highly intelligent cars are what the cars of the future should be like.A. Experts say that we cannot do that just yet.B. In the near fut

16、ure, intelligent cars will be put into commercial operation.C. This is the brain of the car.D. But how does an intelligent car control itself?E. It completes the processing of the images sent by the cameras within 100 milliseconds.F. However, it cannot recognize moving people and bicycles on ordinar

17、y roads that have no clear markings on them.10 Musical Training Can Improve Communication SkillsAmerican scientists say musical training seems to improve communication skills and language retardation. They found that developing musical skills involves the same process in the brain as learning how to

18、 speak. The scientists believe that could help children with learning disabilities.41 She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument and watching other musicians. This process is not much dif

19、ferent from learning how to speak. 42She further explains musical training and learning to speak each make us think about what we are doing. She says speech and music pass through a structure of the nervous system called the brain stem. 43 Until recently, experts have thought the brain stem could no

20、t be developed or changed. But Professor Krauss and her team found that musical training can improve a persons brain stem activity.The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The Individuals wore

21、the electrode while they watched a video of someone speaking and a person playing a musical instrumentthe cello. 44 The study found that the more years of training people had, the more sensitive they were to the sound and rhythm of the music. Those who were involved in musical activities were the sa

22、me people in whom the improvement of sensory events was the strongest. 45 She says using music to improve listening skills could mean they hear sentences and understand facial expressions better.A. Both involve different senses.B. Nina Krans is a neurobiologist (神经生物学家) at Northwestern University in

23、 Illinois.C. Some disabled children attended the musical training class.D. It shows the importance of musical training to children with learning disabilities.E. Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech.F. The brain stem controls o

24、ur ability to hear.15 Sleeping GiantRight now, an eruption is brewing in Yellowstone National Park. Sometime during the next two hours, the most famous geyser. Old Faithful, will begin gurgling boiling water and steam. 41Old Faithful is not only a spectacular sight) its also a constant remainder tha

25、t Yellowstone sits on one of the largest volcanoes in the world. If youve never heard of Yellowstones volcano, youre not alone. 42 Yet it has erupted three times during the last 2 million years. And one of those eruptions spewed enough volcanic ash and other debris to blanket half the United States.

26、Yellowstones volcano is sometimes called a “supervolcano“, or extremely large and explosive caldera volcano. 43 this supervolcano formed over a hot spot, an extremely hot area in Earths mantle. John Valley, a volcano professors, said that as the crust moves across a hot spot, the hot spot melts a se

27、ction of the plate moving over it, forming “one volcano after another“.The Yellowstone hot spot melts thick continental crust, which may cause catastrophic eruptions. According to experts the eruptions that created each of the three calderas in and around Yellowstone National Park were larger than a

28、ny other volcanic eruption in recorded history. The most recent eruption, which happened 640, 000 years ago, produced at least 1, 000 cubic kilometers of ash and debris, which blanketed most of the western half of the United States. 44Geological evidence shows Yellowstone has blown its stack every 7

29、00, 000 years or so. “If nature were truly that regular and reliable, we would be due for another eruption soon, “ said Valley. “However, these processes are subject to variability, so we dont really know when the next eruption will happen.“45 It is the volcanic energy that powers the geysers and ho

30、t springs, creates the mountains and canyons, and generates the unique ecosystems that support Yellowstones diverse wildlife.A. Three calderas make up more than a third of Yellowstone National Park.B. The first Yellowstone eruption, 2 million years ago, released more than double that amount of ash a

31、nd debris.C. The volcano is so inconspicuous (不显眼的) that few people know it exists.D. Then, an enormous fountain will shoot high into the air.E. While the active geologist processes at Yellowstone do pose some risk to the public, they also make it a unique treasure.F. Yellowstone National Park attra

32、cts the interest of geologists the world over.20 Robotic Highway ConesA University of Nebraska professor has developed robotic cones and barrels._41 _They can even be programmed to move on their own at any particular part of the day, said shane Farritor, an assistant professor of mechanical engineer

33、ing at Nebraska.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. 42 “It just seems like a very good application for robots, “ Farritor said. “The robotic cones would also help remove remove people from hazardous jobs on

34、the highway putting barrels and cones into place, “ Farritor said in a report on his creation._43_This fund allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard.The robots are placed at the bottom of the cons and barrels and are small enough not

35、to greatly change the appearance of the construction aides. “It would look exactly te same, “ Farritor said. “Normally theres a kind of rubbery, black base to them. 44 “Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they mig

36、ht 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 t be picked up and moved as the operation proceeds. “That way you dont have to block off a 10-mile strip for the operation. “ Farritor

37、said.While prototypes have been made, they are not in use anywhere. Farritor said he has applied for a patent and is considering what to do nest. 45 He is also thinking about marketing the robots to roads departments and others across the country who may benefit from them.A. And they can return to t

38、he original place at the end of the day.B. He is thinking about starting a small business.C. Farritor was “Inventor of the Year“ in 2003.D. Work on the idea began in 2002 using a National Academy of Sciences grant.E. We replace that with a robot.F. These robotic cones and barrels can move out of the
