Pool Watch

　　Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble. A report 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 pager (呼机). 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. AI software analyses the images to work out swimmers' trajectories (轨迹). 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.

　　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" (预先警戒) 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 (使模糊) 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 (时钟装置) radio. Baylis runs a company that installs swimming pools - and he was once an underwater escapologist (脱身杂技演员) with a circus (马戏团). "1 say full marks to them if this works and can save lives," he says.

　　11 AI means the same as_________.

　　A　an image.

　　B　an idea.

　　C　anything immobile.

　　D　artificial intelligence

　　12 To save a life, AI software must be able to_________.

　　A　descend in the water.

　　B　videotape every movement.

　　C　distinguish between a swimmer and a shadow

　　D　save a life within a few months.

　　13 How does Poseidon save a life?

　　A　It orders an underwater robot to rescue the drowning swimmer.

　　B　It alerts the lifeguard.

　　C　It displays the swimmer's shadow on the screen.

　　D　It watches the pool through dozens of overhead cameras.

　　14 Which of the following statements about Travor Baylis is NOT true?

　　A　He owns a swimming pool.

　　B　He invented the clockwork radio.

　　C　He was once an entertainer.

　　D　He runs a company.

　　15 How does Baylis look at the Poseidon system?

　　A　He thinks it is too expensive.

　　B　He thinks it is a good system.

　　C　He thinks it is not efficient enough.

　　D　He thinks it is as good as the British pool Watch system.

Garlic

　　From early times man has used garlic (大蒜). The Bible speaks of it. The Israelites (古以色列人) were once far from home. They cried out to Moses, their leader, for the foods they loved: leeks (韭菜), onions, and garlic. The Romans, like the Israelites, loved to eat garlic. And they hung bags of garlic around their necks. _____(1) They also thought it would keep them from getting sick.

　　A similar idea is still held. Many people take garlic thinking it will prevent or cure disease. Most doctors say it does no such thing. _____(2) Its smell may force people to stay far apart. At least then they can't pass germs on to each other. _____(3) What if you're in a play, for instance? Actors have been known to forget their lines because they couldn't stand the garlic smell on a fellow actor's breath. Some have even made up new lines and actions that kept them far away from the one who had eaten garlic.

　　Through the years man has tried to cope with the smell of garlic. _____(4) We now know why. It's been found that the oils of the garlic do not stick to the teeth, Garlic tongue, or gums (齿龈). They go into the lungs instead. From there they are breathed out. They pass out through the skin too.

　　Strange as it seems, food may have a great deal of garlic in it without smelling or tasting strong. It all depends on how it is cooked. French cooks make a good soup with whole cloves (瓣) of garlic. They use more than thirty cloves in one bowl of soup. But they take care not to crush them. And they cook them whole. _____(5) And as the cloves cook they change in some strange way. The soup turns out to be delicious. It's not strong at all.

　　A　But no medicine, mouthwash, chewing gum, or toothpaste seems to help much

　　B　As a result, the strong oils stay in the cloves.

　　C　They say it may help in one way, though.

　　D　Many people eat garlic.

　　E　But keeping your distance can be hard at times.

　　F　They hoped it would keep away the evil eye.
