[单项选择]Passage One
I have an infatuation(迷恋)with autumn. The colors of the season, and the smells, have always thrilled me. I have always found joy in this time of year. The last few autumns of my life, however, I recollect in shades of gray rather than cheerful oranges and yellows.
When I became a single mother, every aspect of life took on new meaning. Since I was used to carrying out most of the parental duties without much help during my marriage, I truly did not foresee how different parenting would become after the marriage was over. But suddenly I realized I was a statistic. The daily routine was not changed so much; it was the angle at which I had begun to look at life.
I believed my ex-husband’s lawyer was tracking every grade the children made, and I was under a microscope in this new town where the children and I moved our "broken home." I feared having to eventually establish my family with each new teacher and each new term as a single-parent family. I just wanted

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.
Al 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)."I say full marks to them if this works and can save lives,"he says.
How does Baylis look at the Poseidon system?
A.He thinks it is too expensive.
B.He thinksi t 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.
