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

9、gation system for the blind that announced the surrounding objects through stereo headphones that were mounted to a computer in his back-pack (背包),creating 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 g

One day, its developers hope, miniaturized (小型化)versions of this navigation device, which now weighs 28 pounds, 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

11、. Roberta Klatzky, a psychologist at Carnegie Mellon University who is working with Dr. Smith to develop the navigating device. Dr. Michael Oberdor 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 a

12、round, and that Zabars delicatessen(熟食店) was up ahead. This navigation system tells you not just where there are obstacles, but your overall location geographically. “ It lets blind users construct a mental map of new surroundings and learn their way around.The navigation system uses signals from a

13、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 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 im

14、mediately his or her distance or direction, and use that information for guidance. While no one knows whether it is because blind people tend to 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 cruci

15、al 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 map of your surroundings so you can navigate, “ Dr. Oberdor said.（分数：7.00）(1).With the help of this sonic device, obstacles in the way will speak out their

Nicola Waiters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a “calorimeter“ (热量测量室)is one way to find

20、 out. The signs above the two rooms read simply “Chamber One“ and “Chamber Two“, these are the calorimeters: 4m by 2m white-walled rooms where human volunteers are locked up in the name of science. Outside these rooms another sign reads, “Please do not enter-work in progress“ and in front of the roo

21、ms advanced machinery registers(记录) every move the volunteers make. Each day, meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer.2. Nicola Waiters is one of the twenty volunteers who, over the past eight months, have spent varying perio

22、ds inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help her with training and fitness program. A self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert(广告)for volunteers at her gym

23、 and as she is interested in the whole area of diet and exercise, she thought she would help out.3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence(次序) was repeated four times over six weeks. She arrived at the calorimeter at 8 :

24、 30 a. m. on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, her daily exercise routine timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and samples were taken for

25、analysis.4. The scientists helped volunteers impose (确立)a kind of order on the long days they faced in the room. “The first time, I only took one video and a book. But it was OK, because I watched TV the rest of the time, “says Nicola. And twice a day she used the exercise bike. She pedaled(踩踏板) for

26、 half an hour, watched by researchers to make sure she didnt go too fast.5. It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel full. Believing that they may now know what encourages

27、 people to overeat, the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further sessions.A. What does the calorimeter look like inside?B. what program was designed for the experiments?C. What is a calorimeter?D. What was th

Between meetings and appointments,

31、 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 late, Im sunk. The problem is that its hard if my clocks arent correct. Even the digital clocks can display time

32、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 gets the time directly from the U.S. Atomic Clock in Fort Collins, Colorado, the standard for time-keeping all over

33、 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 itself to the exact hour, minute and second. The U. S. Atomic Clock is accurate to ten billionths of a second per

34、 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 remember to “spring forward“ or “fall back“. The desktop clock model is the only atomic Clock that will not lose tim

35、e 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 the latest scientific technology. It comes in two styles, the wall clock and the desktop model. Both are designed t

36、o 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 time zones. It weighs only eight ounces, and is the perfect travel clock It also has dual alarms, perfect for couples.

37、 Both the desktop and the wall models have an internal antenna for good reception without unattractive wires.（分数：15.00）(1).What is the passage mainly about?（分数：3.00）A.The importance of timing.B.The working principle of an ordinary clock.C.The features of the U.S. Atomic Clock.D.The manufacturer of t

38、he U.S. Atomic Clock.(2).The U.S. Atomic Clock is so accurate that_.（分数：3.00）A.it gains only a second in a million yearsB.its deviation is within a second in a million yearsC.it loses only a second in a million yearsD.its deviation can never be detected(3).The U.S. Atomic Clock adjusts automatically

39、 for_.（分数：3.00）A.spring timeB.summer timeC.autumn timeD.winter time(4).Why does the writer want to know the time down to the minute?（分数：3.00）A.Because he always chairs meetings.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

40、to follow.(5).Which of the following about the U.S. Atomic Clock is NOT true?（分数：3.00）A.It has dual alarms.B.It has an outside antenna.C.It is a perfect travel clock due to its light weight.D.It displays two time zones.B第二篇/BWhatever Happens to Old Computers?You have just got a new computer and you

41、are delighted with it. It is doing everything you wanted your new computer to do. But what are you going to do with your old computer? Have you ever wondered what other people do with their old computers? In the past they have often paid high prices for their old computers, but how much do you think

42、 these computers are worth now? Few people want to buy a computer that has become out of date or has been replaced by a newer model. Unfortunately, the only thing you can do with a computer that you have had for five or six years is to throw it away with your other garbage!What do many people do whe

43、n they try to sell their old computers? Foolishly, they take into account its original cost and then reduce the price according to the age of the computer rather like a second-hand car. They are wrong. They forget that new computers are becoming cheaper every day, making old computers almost worthle

44、ss. In 1985, for example, a good computer cost over US $ 4,000. Ten years later its owner would be lucky to get $ 400. Although old computers are still more useful than old typewriters, you must be careful about buying a second-hand computer. The microchips in a computer may last a long time, but th

45、e hard disk will not. It will probably cost more to replace the hard disk with a new one than the computer itself is worth. Moreover, replacing the old processor in a computer is simply not worth the trouble as it will probably be incapable of running newer software. Ultimately, saving and repairing

46、 an old computer is like building a car from spare parts. It is far cheaper to buy a new car. One well-known computer magazine recently compiled a list of ten things to do with an old computer. One suggestion was to donate it to charity or give it as one of the small prizes in a competition. The fin

47、al suggestion was to store it in a safe place and hope that it would become a collectors item in fifteen or twenty years though the article in the magazine admitted that in fifteen or twenty years there may be so many old computers that they will all be worthless.Whatever you decide to do with an ol

48、d computer will not alter the fact that it will be useless as a piece of technology in several years. The world of computers is quickly changing and eventually all computers will not only be integrated with video telephone and run CD-ROM disks, but will also be able to perform a countless number of

49、tasks which as yet we cannot even imagine. All these uses will require much more advanced and powerful machines that will automatically condemn even the most advanced computer today to the garbage can of the twentieth century.（分数：15.00）(1).According to the passage, if a computer is old, youd better_.（分数：3.00）A.repair itB.threw it awayC.sell it a
