Passage Two:Questions 26 to 30 are based on the following passage.Attention to detail is something everyone can and should do—especially in a tight job market. Bob Crossley, a human-resources expert notices this in the job applications that come across his desk every day. “It’s amazing how many candidates eliminate themselves.” he says.Resume (简历) arrive with stains. Some candidates don’t bother to spell the company’s name correctly. Once I see a mistake, I eliminate the candidate, Crossley concludes. “If they cannot take of these details, why should we trust them with a job?”Can we pay too much attention to detail? Absolutely. Perfectionists struggle over little things at the cost of something larger they work toward, “To keep from losing the forest for the trees”, says Charles Garfield, associate professor at the University of California, San Francisco, “We must constantly ask ourselves how the details we’re working on fit into the larger picture. If they don’t, we should drop them and move to something else”.Garfield compares this process to his work as a computer scientist at NASA. “The Apollo II moon launch was slightly off-course 90 percent of the time.” Says Garfield, “But a successful landing was still likely because we knew the exact coordinates of our goal. This allowed us to make adjustments as necessary.” Knowing where we want to go helps us judge the importance of every task we undertake.Too often we believe what accounts for others’ success is some special secret or a lucky break (机遇). But rarely is success so mysterious. Again and again, we see that by doing little things within our grasp well, large rewards follow.第26题：According to the passage, some job applicants were rejected ________.A) because of their carelessness as shown in their failure to present a clean copy of a resumeB) because of their inadequate education as shown in their poor spelling in writing a resumeC) because they failed to give detailed description of their background in their applicationsD) because they eliminated their names from the applicants’ list themselves

第三篇 Pool 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 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 paper. In trials at a pool in Ancenis, near Nantes, it saved a life within just a few months, says Alistair MeQuade, 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. 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 “projecting” 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 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 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 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 pools—and he was once an underwater escapologist with a circus. “I say full marks to them if this works and can save lives,” he says. But he adds that any local authority spending ￡30,000-plus on a Poseidon system ought to be investing similar amounts in teaching children to swim.41. AI means the same as A. an image. B. an idea.
