7、 most convenient form of communication, in the future we want essentially natural conversations with computers. The primary point of contact will be a simple device that will act as our window into the world. It will have to be small enough to slip into pour pocket, so there will be a screen but no

8、keyboard: you will simply talk to it. The device will be permanently connected to the Internet and will beep relevant information up to you as it comes in. Such devices will evolve naturally in the next five to ten years. Just how quickly people will adapt to a voice-based Internet world is uncertai

9、n. Many believe that, initially at least, we will need similar conventions for the voice to those we use at present on screen : click, back, forward, and so on. But soon you will undoubtedly be able to interact by voice with all those IT-based services you currently connect with over the Internet by

10、 means of a keyboard. This will help the Internet serve the entire population. Changes like this will encompass (围绕、包围 ) the whole world. Because English is the language of science, it will probably remain the language in which the technology is most advanced, but most speech, recognition techniques

11、 are transferable to other languages provided (假如、若是 ) there is sufficient motivation to undertake the work. Of course, in any language there are still huge problems for LIS to solve. Carefully dictated, dear speech can now be understood by computers with only a 4 5 percent error rate, but even the

12、most advanced technology still records 30 40 percent errors with spontaneous speech. Within ten years we will have computers that respond to goal-directed conversation, but for a computer to have a conversation that takes into account human social behaviors is probably 50 years off. We are not going

13、 to be chatting to the big screen in the living room just yet. In the past insufficient speed and memory have held LIS back, but these days they are less of an issue. However, there are those in the IT community who believe that current techniques will eventually hit a brick wall. Personally, I beli

14、eve that incremental (不断增长的 )developments in performance are more likely. But it is true that by about 2040 or so, computer architectures will need to become highly parallel(并行的 ) if performance is to keep increasing. Perhaps that will inspire some radically new approaches to speech understanding th

15、at will replace the methods we are developing now. 16 In the future, people will talk to computer instead of typing and clicking. （ A） Right （ B） Wrong （ C） Not mentioned 17 In the future, computers will be as small as match boxes. （ A） Right （ B） Wrong （ C） Not mentioned 18 Besides English, French

16、is another frequently used language of science. （ A） Right （ B） Wrong （ C） Not mentioned 19 Within ten years, computers can make conversations which take human social behavior into account. （ A） Right （ B） Wrong （ C） Not mentioned 20 Computers can understand clear and carefully dictated speech more

17、accurately than spontaneous speech. （ A） Right （ B） Wrong （ C） Not mentioned 21 Insufficient memory of the computer is still a problem. （ A） Right （ B） Wrong （ C） Not mentioned 22 According to the writer, current technique has no room for improvement. （ A） Right （ B） Wrong （ C） Not mentioned 三、 概括大意

19、ffer the consequences. Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept o

20、nly 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a nights sleep than 8-hour sleepers. These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good nights rest may not need to se

21、t aside more than 8 hours a night. He added that “it might be a good idea“ for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. Previous studies have shown the potential dangers of chr

22、onic shortages of sleep - for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, i

23、n which participants indicated how much they slept during the Week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having fatigue interfere with day-to-day functioning

24、. Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evide

25、nce, he added that one way to help insomnia is to spend less time in bed. “It stands to reason that if a person spends too long a time in bed, then theyll spend a higher percentage of time awake. “ he said. A. Keprikes Research Tool B. Dangers of Habitual Shortages of Sleep C. Criticism on Kripkes R

Classification of Sleen Problems 23 Paragraph 2 _ 24 Paragraph 4 _ 25 Paragraph 5 _ 26 Paragraph 6 _ 26 A. fall asleep again.

Between meetings and appointments, deadlines and conference calls, my schedule requires that I know the time down to the minute. Ev

29、en 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 inaccurately. Dead batteries, time changes, any of these can cause a clock to be inaccurate. Now

30、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 the world. The Atomic Clock by Acorn is the most accurate, reliable and convenient timepiece you

31、 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 day. This means that the clock deviates less than one second over a one million-year period. Th

32、e 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 time with low power or when you change its batteries. The most accurate clock in the world is of no

33、 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 to be functional and easy to use. The desk clocks display features the exact time (in hours, min

34、utes 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. Both the desktop and the wall models have an internal antenna for good reception without unatt

35、ractive wires. 31 What is the passage mainly about? （ 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 the U.S. Atomic Clock. 32 The U.S. Atomic Clock is so accurate that_. （ A） it gains only a second i

36、n a million years （ B） its deviation is within a second in a million years （ C） it loses only a second in a million years （ D） its deviation can never be detected 33 The U.S. Atomic Clock adjusts automatically for_. （ A） spring time （ B） summer time （ C） autumn time （ D） winter time 34 Why does the

37、writer want to know the time down to the minute? （ 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 to follow. 35 Which of the following about the U.S. Atomic Clock is NOT true?

38、 （ 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. 35 Whatever Happens to Old Computers? You have just got a new computer and you are delighted with it. It is doing everything you wanted your new compu

39、ter 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 these computers are worth now? Few people want to buy a computer that

40、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 when they try to sell their old computers? Foolishly, they take into acco

41、unt 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 worthless. In 1985, for example, a good computer cost over US $ 4, 000. Ten y

42、ears 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 the hard disk will not. It will probably cost more to replace the hard

43、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 an old computer is like building a car from spare parts. It is far c

44、heaper 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 final suggestion was to store it in a safe place and hope that it would

45、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 old computer will not alter the fact that it will be useless as a piec

46、e 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 tasks which as yet we cannot even imagine. All these uses will requi

47、re much more advanced and powerful machines that will automatically condemn even the most advanced computer today to the garbage can of the twentieth century. 36 According to the passage, if a computer is old, youd better_. （ A） repair it （ B） threw it away （ C） sell it at a high price （ D） put it i

48、n a safe place for future use 37 The author says that an old computer can be sold at_. （ A） a high price （ B） a very low price （ C） half of its original price （ D） its original price 38 The passage tells us that it will cost far more to repair an old computer than to_. （ A） buy a new one （ B） buy a

49、new car （ C） repair an old car （ D） build a car from spare parts 39 The word “donate“ (Line 2, Paragraph 4)is closest in meaning to_. （ A） give （ B） send （ C） take （ D） move 40 The author argues that the most advanced computer today_. （ A） is useless （ B） is worthless （ C） is cheap （ D） will eventually be out of date 40 Forecasting Methods There are several different methods that can be used to create a forecast. The method a forecas
