As Dr. Smith walked along the campus, places and impediments (障碍物 ) in h

8、is path seemed to call out their names to him, “library here, library here“, “bench here, bench here“. Dr. Smith was testing a prototype(样机 ) navigation system for the blind that announced the surrounding objects through stereo headphones that were mounted to a computer in his back-pack (背包 ), creat

9、ing virtual reality landscape(仿真景象 ). The information came not from some miniature radar but from the signals broadcast by the militarys network of global positioning satellites(全球定位卫星 ). One day, its developers hope, miniaturized (小型化 )versions of this navigation device, which now weighs 28 pounds,

10、 will help the blind navigate unfamiliar neighborhoods. “With this system you do not need to know a thing in advance about where you are going, “ said Dr. Roberta Klatzky, a psychologist at Carnegie Mellon University who is working with Dr. Smith to develop the navigating device. Dr. Michael Oberdor

11、 of the National Eye Institute said, “A blind person could walk down the street and know not just that he was at 80th and Broadway, but what stores are around, and that Zabars delicatessen(熟食店 ) was up ahead. This navigation system tells you not just where there are obstacles, but your overall locat

12、ion geographically. “ It lets blind users construct a mental map of new surroundings and learn their way around. The navigation system uses signals from a computerized map to create a “virtual acoustic display(仿真声音显示 )“ This is a talking map in which large objects seem to announce themselves in the

13、headphones with the precise timing and loudness that would be the case if the objects were actually making a sound. This allows the blind person to sense immediately his or her distance or direction, and use that information for guidance. While no one knows whether it is because blind people tend to

14、 develop a sharper sense of hearing. Those who have tried the system say that they quickly adapt to locating an object through the sounds. “One of the crucial features of this system is that it takes advantage of sensory psychophysics(感官心理物理学 )-how the brain interprets signals from outside to make a

15、 map of your surroundings so you can navigate, “ Dr. Oberdor said. 16 With the help of this sonic device, obstacles in the way will speak out their name. （ A） Right （ B） Wrong （ C） Not mentioned 17 Dr. Smith hopes to make this device lighter so as to help the blind navigate unfamiliar places. （ A） R

20、短文后有 5道题。请根据短文内容，为每题选 1个最佳选项。 26 Accurate Timer These days time is everything. Between meetings and appointments, deadlines and conference calls, my schedule requires that I know the time down to the minute. Even on weekends, I have a football team to coach, shows to tape and planes to catch. If Im

21、late, Im sunk. The problem is that its hard if my clocks arent correct. Even the digital clocks can display time inaccurately. Dead batteries, time changes, any of these can cause a clock to be inaccurate. Now there is no need to worry, because advanced radio technology has produced a clock which ge

22、ts the time directly from the U.S. Atomic Clock in Fort Collins, Colorado, the standard for time-keeping all over the world. The Atomic Clock by Acorn is the most accurate, reliable and convenient timepiece you can have. Every morning at 1:00 a. m, this “smart“ clock in Colorado automatically resets

23、 itself to the exact hour, minute and second. The U. S. Atomic Clock is accurate to ten billionths of a second per day. This means that the clock deviates less than one second over a one million-year period. The Atomic Clock even adjusts automatically for daylight saving time, so you dont have to re

24、member to “spring forward“ or “fall back“. The desktop clock model is the only atomic Clock that will not lose time with low power or when you change its batteries. The most accurate clock in the world is of no use if it is difficult to operate. The Acorn Atomic Clock is engineered in Germany using

25、the latest scientific technology. It comes in two styles, the wall clock and the desktop model. Both are designed to be functional and easy to use. The desk clocks display features the exact time (in hours, minutes and seconds), month and date, or you can choose to display any two U. S. or world tim

26、e zones. It weighs only eight ounces, and is the perfect travel clock It also has dual alarms, perfect for couples. Both the desktop and the wall models have an internal antenna for good reception without unattractive wires. 27 What is the passage mainly about? （ A） The importance of timing. （ B） Th

27、e working principle of an ordinary clock. （ C） The features of the U.S. Atomic Clock. （ D） The manufacturer of the U.S. Atomic Clock. 28 The U.S. Atomic Clock is so accurate that_. （ A） it gains only a second in a million years （ B） its deviation is within a second in a million years （ C） it loses o

29、 B） Because he has got a football team to coach. （ C） Because he is the pilot of a plane. （ D） Because he has a very tight timetable to follow. 31 Which of the following about the U.S. Atomic Clock is NOT true? （ A） It has dual alarms. （ B） It has an outside antenna. （ C） It is a perfect travel cloc

30、k due to its light weight. （ D） It displays two time zones. 31 Radiation Effect Space is a dangerous place, not only because of meteors (流星 )but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth light, gets through, and this is essential

31、for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation, but their spac

32、esuits or the walls of their spacecrafts, if they are inside, do prevent a lot of radiation damage. Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem“ (“雷姆 ”). Scientists have reason to think that a man can put up with far more radiation than 0.1 rem

33、without being damaged, the figure of 60 reins has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged , and this will not be discovered until the birth of deformed(畸形的

34、)children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a larger amount of reins. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been

35、 quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage clone by radiation , but no really effective ones have been found so far. 32 According

36、 to the first paragraph, the atmosphere is essential to man in that_。 （ A） it protects him against the harmful rays from space （ B） it provides sufficient light for plant growth （ C） it supplies the heat necessary for human survival （ D） it screens off the falling meteors 33 We know from the passage

37、 that_. （ A） exposure to even tiny amounts of radiation is fatal （ B） the effect of exposure to radiation is slow in coming （ C） radiation is avoidable in space exploration （ D） astronauts in spacesuits neednt worry about radiation damage 34 The harm radiation has done to the Apollo crew members_. （

38、 A） is insignificant （ B） seems overestimated （ C） is enormous （ D） remains unknown 35 It can be inferred from the passage that_. （ A） the Apollo mission was very successful （ B） protection from space radiation is no easy job （ C） astronauts will have deformed children or grandchildren （ D） radiatio

39、n is not a threat to well-protected space explorers 36 The best title for this passage would be_. （ A） The Atmosphere and Our Environment （ B） Research on Radiation （ C） Effects of Space Radiation （ D） Importance of Protection Against Radiation 37 Light Night, Dark Stars Thousands of people around t

40、he globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家 ) with the University Corporation for Atmospheric Research (UCAR) in Boulder,

41、Colo. But when people are surrounded by city lights, he says, theyre lucky to see 150 stars. If youve ever driven toward a big city at night and seen its glow from a great distance, youve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources st

42、reams into space and illuminates(照亮 ) the night sky. This haze(薄雾 ) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult. Dust and particles of pollution from factories and industries worsen the effects

43、 of light pollution. “If one city has a lot more light pollution than another“, Ward says, “that city will suffer the effects of light pollution on a much greater scale“. Hazy skies also make it far more difficult for astronomers to do their jobs. Cities are getting larger. Suburbs are growing in on

44、ce dark, rural areas. Light from all this new development is increasingly obscuring(使变模糊 ) the faint(微弱的 ) light given off by distant stars. And if scientists cant locate these objects, they cant learn more about them. Light pollution doesnt only affect star visibility. It can harm wildlife too. Its

45、 clear that artificial light can attract animals, making them go off course. Theres increasing evidence, for example, that migrating(迁徙 ) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr., a scientist at Clemson University in South Carolina. “When light occurs at nigh

46、t“, he says, “it has a very disruptive(破坏性的 ) influence“. Sometimes birds fly into lighted towers, high-rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year. 37 On a clear night, people can see_ （ A） 150 stars. （ B） hundreds of stars. （

47、C） one thousand stars. （ D） more than 14,000 stars. 38 Light pollution occurs when_ （ A） artificial lights illuminate the night sky. （ B） the moon lights up the night sky. （ C） too many stars are visible in the night sky. （ D） streetlights are turned off. 39 Nowadays even suburbs are becoming unsuit

48、able for astronomers to do their jobs because_ （ A） the night sky there is too dark. （ B） the once dark areas are also polluted by lights. （ C） these areas are not polluted by chemicals. （ D） these areas are less developed. 40 How does light pollution affect wildlife? （ A） Animals may go off course.

49、 （ B） It helps migrating birds find their homes. （ C） Animals are afraid to go out after sunset. （ D） It helps birds fall asleep. 41 The title “Light Night, Dark Stars“ means_ （ A） the night sky is brightly lit up and stars are black. （ B） lights appear at night and stars are seen in the dark. （ C） city lights at night illuminate stars in the sky. （ D） city lights illuminate the night sky, making stars invisible. 五、 补全短文 (第 46-50，每题
