7、ey have no memory at all: “I just can“t remember a thing!“ But of course we all have a memory. Our memory tells us who we are. Our memory helps us to make use in the present of what we have learnt in the past. In fact we have different types of memory. For example, our visual memory helps us recall

8、facts and places. Some people have such a strong visual memory, they can remember exactly what they have seen, for example, pages of a book, as a complete picture. Our verbal (言语的) memory helps us remember words and figures we may have heard but not seen or written: items of a shopping list, a chemi

9、cal formula, dates, or a recipe. With our emotional (情感的) memory, we recall situations or places where we had strong feelings, perhaps of happiness or unhappiness. We also have special memories for smell, taste, touch and sound, and for performing physical movements. We have two ways of storing any

10、of these memories: Our short-term memory stores items for up to thirty secondsenough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items for a lifetime. Older people in fact have a much better long-term memory than short-term. They may forget what t

11、hey have done only a few hours ago, but have the clearest remembrance (记忆) of when they were very young. Psychologists tell us that we only remember few facts about our past, and that we invent the rest. It is as though we remember only the outline of a story. We then make up the details. We often d

15、ge by summer as an alternative, and possibly a competitor, to the DVDformat currently available. 2The new system, called Digital Video Express (Divx), operates like a DVD player, except for the specially coded discs. These will cost $5 for initial viewing over a 48-hour period and can be viewed agai

16、n for additional fees and even purchased for unlimited viewing. 3Divx combines the service of a video rental (出租的) store with the operation of a pay-per-view TV channel. Unlike a rented videotape, though, the Divx disc needn“t be returned. Customers can retain the disc for replay in the future at an

17、 additional fee, or simply throw it away. 4Subsequent plays, or the purchase of unlimited-viewing rights, are billed to the customer“s Divx account and charged to a credit card. The player“s built-in memory keeps track of all Divx plays, and sends this information by toll-free phone modem (调制解调器) to

18、 the Divx record-keeping centre. Each Divx disc and player has a unique identification code, so the system knows which discs have been played and where. 5Some Divx discs could be converted for unlimited play at a price likely to be lower than buying a conventional DVD. Others, called Divx Gold, woul

19、d be sold from the beginning for unlimited play without further charge. Although conventional DVDs will run in a Divx player, conventional DVD players will lack the decoding and communications ability to play. Divx discs. Divx players will be offered by Panasonic, RCA, and Zenith. 6About 100 discs w

24、l WatchSwimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble. The Royal Society for the Prevention of Accidents says that on average 15 people drown in British pools each year, but many more suffer major injury after getting into difficulties. Now a French

25、 company has developed an artificial intelligence system called Poseidon that sounds the alarm when it sees someone in danger of drowning. When a swimmer sinks towards the bottom of the pool, the new system sends an alarm signal to a poolside monitoring station and a lifeguard“s pager. “In trials at

26、 a pool in Ancenis, near Nantes, it saved a life within just a few months,“ says Alistair McQuade, a spokesman for its maker, Poseidon Technologies. Poseidon keeps watch through a network of underwater and overheard video cameras. AI software analyses the images to work out swimmers trajectories (轨道

27、，轨线). To do this reliably, it has to tell the difference between a swimmer and the shadow of someone being cast onto the bottom or side of the pool. “The underwater environment is a very dynamic one, with many shadows and reflections dancing around,“ says McQuade. The software does this by “projecti

28、ng“ a shape in its field of view onto an image of the far wall of the pool. It does the same with an image from another camera viewing the shape from a different angle. If the two projections are in the same position, the shape is identified as a shadow and is ignored. But if they are different, the

29、 shape is a swimmer and so the system follows its trajectory. To pick out potential drowning victims, anyone in the water who starts to descend slowly is added to the software“s “pre-alert“ list, says McQuade. Swimmers who then stay immobile on the pool bottom for 5 seconds or more are considered in

30、 danger of drowning. Poseidon double-checks that the image really is of a swimmer, not a shadow, by seeing whether it obscures the pool“s floor texture when viewed from overhead. If so, it alerts the lifeguard, showing the swimmer“s location on a poolside screen. The first full-scale Poseidon system

31、 will be officially opened next week at a pool in High Wycombe, Buckinghamshire. One man who is impressed with the idea is Travor Baylis, inventor of the clockwork radio. Baylis runs a company that installs swimming poolsand he was once an underwater escapologist (表演脱身术的人) with a circus. “I say full

32、 marks to them if this works and can save lives,“ he says. But he adds that any local authority spending 230,000plus on a Poseidon system ought to be investing similar amounts in teaching children to swim.（分数：15.00）(1).AI means the same as _.（分数：3.00）A.an imageB.an ideaC.anyone in the waterD.artific

33、ial intelligence(2).What is required of AI software to save a life?（分数：3.00）A.It must be able to swim.B.It must keep walking round the pool.C.It can distinguish between a swimmer and a shadow.D.It can save a life within a few months.(3).How does Poseidon save a life?（分数：3.00）A.He plunges into the po

36、y unthinkable: Can buildings be designed to withstand catastrophic blasts (爆炸) inflicted by terrorists? Ten days after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) headquarte

37、red (总部在某地) at UB traveled to ground zero as part of a project funded by the National Science Foundation. Visiting the site as part of an MCEER reconnaissance (事先考查) visit, they spent two days beginning the task of formulating ideas about how to design such structures and to search for clues on how

38、to do so in buildings that were damaged but still are standing. “Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage,“ said M. Bruneau, Ph.D. “Our immediate hope is that we ca

39、n develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks,“ he added. Photographs ta

One building a block away from the towers remains standing, but was badly damaged. “This building is many meters away from the World Trade Ce

41、nter and yet we see a column there that used to be part of that building,“ explained A. Whittaker, Ph. D. “The column became a missile that shot across the road, through the window and through the floor.“ The visit to the area also revealed some surprises, according to the engineers. For example, th

42、e floor framing system in one of the adjacent buildings was quite rugged, allowing floors that were pierced by tons of falling debris to remain intact. “Highly redundant ductile (有延展性的) framing systems may provide a simple, but robust strategy for blast resistance,“ he added. Other strategies may in

43、clude providing alternate paths for gravity loads in the event that a load-bearing column fails. “We also need a better understanding of the mechanism of collapse,“ said A. Whittaker. “We need to find out what causes a building to collapse and how you can predict it.“ A. Reinhorn, Ph. D. noted that

44、“Earthquake shaking has led to the collapse of many buildings in the past. It induces dynamic response and extremely high stresses and deformations in structural components. Solutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant de

Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present.“（分数：15.00）(1).The question raised in the first paragraph is one _.（分数：3.00）A.that was asked by structural engineers a month agoB.that is too difficult for structural engineers to a
