Millions of families sat down in their living rooms one evening last August to watch a live Madonna Concert from France, telecast on the cable network Home Box Office. Because Madonna. is such a huge international star--and because the telecast was heavily promoted and aired in prime time on a weekend--millions of children certainly watched with their parents.
What happened on all those screens was that Madonna repeatedly used the one obscene word that has been routinely barred from the public airwaves.
We live in an anything - goes age, so the show’ s witless and purposely vulgar content was not surprising. The language itself was nothing that has not been heard in movies or on cable - TV comedy specials. The surprising thing was that so few parents called HBO to object. A spokesperson for the network said the complaints" were not by any stretch of the imagination overwhelming"--and that the Madonna con cert was the highest - rated original entertainment program in the network’ s history. Apparently, America’ s parents have totally given up hope that they can control what their children are exposed to on TV.
My point isn’ t, really, about Madonna.. Though I don’ t happen to find her calculated outrage particularly interesting she is free to make her money anyway she chooses. Marginally talented singers have been packaging rebellion for decades, and it always seems to sell, especially to young people. Madonna has done a very good job marketing her product.
What is most troubling is that her product appeared in America’ s homes during prime time on a Sunday, and people seemed to think it was no big deal. Television, in a way that now seems quaint, was once considered almost sacred ground when it came to certain material-precisely because children were watching. But the country has been so beaten down by a lessening of public standards that obscenities can be telecast to millions of families without causing even a ripple of protest.
What of the argument (that parents should just turn off the TV if they don’ t like the programming) It’ s valid--but there was no warning before Madonna launched into her first rapid - fire round of obscenities. Although the telecast was promoted as being live, it actual ly was taped hours before. The network knew what it was sending out. Yet it did so without deletions or an advisory notice at the beginning of the show. This was "a creative decision," HBO says.
Those children will hear worse in their lifetimes--they probably already have. To telecast a concert like Madonna’ s is no longer considered particularly controversial. But to wonder publicly about the wisdom of it--to say that delivering such a performance to the nation’ s children is wrong—that is considered controversial. To say it is wrong is to seem out of step with the rest of the world. But it is wrong. It is dead wrong.

A:Quite a few parents called HBO to object. B:They regarded it as the highest rated original entertainment program in the network' s history. C:They were outraged. D:They didn' t care much about it.

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 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. "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 overheard video cameras. AI software analyses the images to work out swimmers trajectories (轨道，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 "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 (表演脱身术的人) 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 230,000—plus on a Poseidon system ought to be investing similar amounts in teaching children to swim.
