Pool Watch
Swimmers 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 poois 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 pooi-
side monitoring station and a lifeguard's pager. In trials at 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 overhead video cameras.Al software
analyses the images to work out swimmers'trajectories.To do this reliably,it has to tell the difference be-
tween 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一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.

参考答案
参考解析
解析：AI由artificial和intelligence的首字母组合而成，artificial intelligence的意思是．'‘人工智 能”，符合文意。A项的意思为“一个图像”;B项的意思是“一个想法”;C项的意思是“水中的 任何一个人”，均不符合文意。
本题问的是：为了拯救一条生命，人工智能软件必须具备什么样的条件。这个意思可 以从第三段中找到。第三段第三句话“To do this reliably, it has to tell the difference between aswimmer and the shadow of someone being cast onto the bottom or side of the pool."，意思是说：它 （人工智能软件）必须能区分一个游泳的人与投射到池底或池壁的某个人的影子。因此C是正确的答案。
本题问的是：Poseidon是如何挽救生命的？第五段最后一句话是说“If so, it alerts the lifeguard, showing the swimmer' s location on a poolside screen.”假如是这样（图像确实是一个游 泳人的图像），它就会提醒救生员。可见B是正确的答案。
本题问的是：下面这些有关Travor Baylis的命题中哪一个不是真的？A中的run是不及 物动词，应为“跑步”的意思。最后一段中的“Baylis runs a company...”中的run是及物动词， 作“经营”解释。二者不是一回事。可见A是正确答案。B说的是：他发明了机械装置的无线 电。这个选项可以从第六段中找到："One man who is impressed with the idea is Travor Baylis, inventor of the clockwork radio0" C说的是：他曾经是一名职业娱乐节目表演者。D说的是：他经 营一家公司。C和D都可以在第六段里找到。故选A。
rate和regard都有“把······看做······”的意思，但regard后必须跟as。故答案为B。 第二篇 本篇文章主要讲述的是医学杂志的发行及分类。
