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 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 pool-
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 overheard video cameras.Al software analy-
ses 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 under-
water 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 ra-
dio.Baylis runs a company that installs swimming pools一and he was once an underwater escapologist（表演

adds that any local authority spending ￡30,000一plus a on Poseidon system ought to be investing similar

Why Would They Falsely Confess?
Why on earth would an innocent person falsely confess to committing a crime?To most
people,it just doesn't seem logical .But it is logical,say experts,if you understand what
can happen in a police interrogation（审讯）room.
Under the right conditions, people's minds are susceptible（易受影响的）to influence, and t
he pressure put on suspects during police grillings（盘问）is enormous.________(1)
"The pressure is important to understand,because otherwise it's impossible to understand why
someone would say he did something he didn't do.The answer is:to put an end to an
uncomfortable situation that will continue until he does confess."
Developmental psychologist Allison Redlich recently conducted a laboratory study to
determine how likely people are to confess to things they didn't do.________(2)The
researchers then intentionally crashed the computers and accused the participants of hitting
the"alt"key to see if they would sign a statement falsely taking responsibility.
Redlich's findings clearly demonstrate how easy it can be to get people to falsely
confess : 59 percent of the young adults in the experiment immediately comfessd.
__________ (3) Of the 15 to 16 year olds, 72 percent signed confessions ,as did 78
percent of the 1 2-to-1 3-year olds.
"There's no question that young people are more at risk, " says Saul Kassin, a
psychology professor at Williams College,who has done similar studies with similar results.
________(4)
Both Kassin and Redlich note that the entire"interrogation"in their experiments
consisted of a simple accusation一not hours of aggressive questioning一and still,most
participants falsely confessed.
Because of the stress of a police interrogation,they conclude,suspects can become
convinced that falsely confessing is the easiest way out of a bad situation.________(5)
_________（3）
A:In her experiment,participants were seated at computers and told not to hit the"alt" key,because doing so would crash the systems.
B:"In some ways,"says Kassin,"false confession becomes a rational decision."
C:" It's a little like somebody's working on them with a dental（牙齿的）drill," says Franklin Zimring,a law professor at the University of California at Berkeley.
D:"But adults are highly vulnerable too."
E:How could an innocent person admit to doing something he didn't do?
F:Redlich also found that the younger the participant,the more likely a false confession.

Transport and Trade
1.Transport is one of the aids to trade.By moving goods from places where they are plentiful to places where they are scarce,transport adds to their value.The more easily goods can be brought over the distance that separates producer and consumer,the better for trade.When there were no railways,no good roads,no canals,and only small sailing ships,trade was on a small scale.
2.The great advances made in transport during the last two hundred years were accompanied by a big increase in trade.Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand,for instance.Quicker transport makes possible mass-production and big business, drawing supplies from,and selling goods to,all parts of the globe.Big factories could not exist with-out transport to carry the large number of workers they need to and from their homes.Big city stores could not have developed unless customers could travel easily from the suburbs and goods delivered to their homes.Big cities could not survive unless food could be brought from a distance.
3.Transport also prevents waste.Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns.Transport has given us a much greater variety of foods and goods since we no longer have to live on what is produced locally.Foods which at one time could be obtained only during a part of the year can now, be obtained all through the year. Transport has raised the standard of living.
4.By moving fuel,raw materials,and even power,as,for example,through electric cables, transport has led to the establishment of industries and trade in areas where they would have been impossible before.Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The cheaper and quicker transport becomes,the longer the distance over which goods can profitably be carried.Countries with poor transport have a lower standard of living.
5.Commerce requires not only the moving of goods and people but also the carrying of messages and information. Means of communication,like telephones,cables and radio,send information about prices,supplies,and changing conditions in different parts of the world.In this way,advanced communication systems also help to develop trade.
Paragraph 5_______
A:Higher living standard.
B:Importance of transport in trade.
C:Various means of transport.
D:Birth of transport-related industries and trade.

So Many"Earths"
The Milky Way（银河）contains billions of Earth-sized planets that could support life.That's the finding of a new study.It draws on data that came from NASA's top planet-hunting telescope.
A mechanical failure recently put that Kepler space telescope out of service.Kepler had played a big role in creating a census of planets orbiting some 170,000 stars.Its data have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.
The authors of a study,published in The Proceedings of the National Academy of Sciences,conclude that between 14 and 30 out of every 100 stars,with a mass and temperature similar to the Sun,may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth's,but no more than twice that big.The planet also would have to orbit in a star's habitable zone.That's where the surface temperature would allow any water to exist as a liquid.
The new estimate of how many planets might fit these conditions comes from studying more than 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate（推算） to the rest of the stars that the telescope could not see.
The estimate is rough,the authors admit.If applied to the solar system,it would define as habitable a zone starting as close to the Sun as Venus and running to as far away as Mars.Neither planet is Earthlike (although either might have been in the distant past).Using tighter limits,the researchers estimate that between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit.
Four out of every 100 sunlike stars doesn't sound like a big number.It would mean,however,that the Milky Way could host more than a billion Earth-sized planets with a chance for life.
The main task of the Kepler space telescope is to find out planets with similar conditions to Earth's.
A:Right
B:Wrong

Long Bus Ride
Long bus rides are like television shows.They have a beginning,a middle,and an end-with commercials thrown in every three or four minutes. The commercials are unavoidable.They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window."Buy Super Clean Toothpaste.""Drink Good'n Wet Root Beer.""Fill up with Pa-cific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of"You Need It!Buy It Now!"
The beginning of the ride is comfortable and somewhat exciting,even if you've traveled that way before .Usually some things have changed-new houses,new buildings,sometimes even a new road. The bus driver has a style of driving and it's fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring,the ride can be as thrilling as a suspense story. Will the driver pass the truck in time?Will the driver move into the right or the left-hand lane? After a while,of course,the excitement dies down.Sleeping for a while helps pass the middle hours of the ride .Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there's a kind of expectation and excitement in that. The seat,of course,has become harder as the hours have passed.By now you've sat with your legs crossed,with your hands crossed behind your head.
The end comes just at the right time.There are just no more ways to sit.
According to the passage,what do the passengers usually see when they are on a long bus trip?
A: buses on the road.
B: films on television.
C: advertisements on the board.
D: gas stations.

Vibrating Rubber Celiphones
Vibrating rubber celiphones could be the next big thing in mobile communications.They allow people to press the phone to transmit vibrations along with their______(51)words.According to a research team at the MIT Media Lab in Cambridge,Massachusetts,the idea will make______ (52)more fun.
Many mobile phones can already vibrate instead of ringing______(53)you do not want people to know you are getting a call. "But these______ (54) are too simple for subtle（敏感的） communication".______(55)Angela Chang of the lab's Tangible Media Group."They're either on or off,"she says.
But when you hold Chang's rubber cellphone your fingers and thumb wrap around five ______(56)speakers. They vibrate______(57)your skin around 250 times per second.Beneath these speakers sit pressure sensors（传感器）,so you can transmit vibration as well as ______(58)it. When you squeeze with a finger,a vibration signal is transmitted______(59) your caller's corresponding finger,its speed______(60)on how hard you squeeze.
Chang says that within a few minutes of being given the phones,students were using the vibration feature to______(61)emphasis to what they were saying.

Small but Wise
On December 14,NASA blasted a small but mighty telescope into space.The telescope is called WISE
and is about as wide around as a trashcan.Don't let its small size fool you:WISE has a powerful digital
camera,and it will be taking pictures of some of the wildest objects in the known universe,including
asteroids,faint stars,blazing galaxies and giant clouds of dust where planets and stars are born.
"I'm very excited because we're going to be seeing parts of the universe that we haven't seen be-
fore,"said Ned Wright,a scientist who directs the WISE project.
Since arriving in space,the WISE telescope has been circling the Earth,held by gravity in a polar orbit
(this means it crosses close to the north and south poles with each lap).Its camera is pointed outward,away
from the Earth,and WISE will snap a picture of a different part of the sky every 11 minutes.After six months
it will have taken pictures across the entire sky.
The pictures taken by WISE won't be like everyday digital photographs,however. WISE stands for
"Wide-field Infrared Survey Explorer".As its name suggests,the WISE camera takes pictures of features
that give off infrared radiation.
Radiation is energy that travels as a wave.Visible light,including the familiar spectrum of light that be-
comes visible in a rainbow,is an example of radiation.When an ordinary digital camera takes a picture of a
tree,for example,it receives the waves of visible light that are reflected off the tree.When these waves enter
the camera through the lens,they're processed by the camera,which then puts the image together.
Waves of infrared radiation are longer than waves of visible light,so ordinary digital cameras don't see
them,and neither do the eyes of human beings.Although invisible to the eye,longer infrared radiation can
be detected as warmth by the skin.
That's a key idea to why WISE will be able to see things other telescopes can't. Not everything in the
universe shows up in visible light.Asteroids,for example, are giant rocks that float through space一but they
absorb most of the light that reaches them.They don't reflect light,so they're difficult to see.But they do
give off infrared radiation,so an infrared telescope like WISE will be able to produce images of them.During
its mission WISE will take pictures of hundreds of thousands of asteroids.
Brown dwarfs are another kind of deep-space objects that will show up in WISE's pictures.These ob-
jects are "failed" stars一which means they are not massive enough to jump-start the same kind of reactions
that power stars such as the sun.Instead,brown dwarfs simply shrink and cool down.They're so dim that
they're almost impossible to see with visible light,but in the infrared spectrum they glow.
The camera on WISE_________.
A:is equipped with expensive computers
B:produces images of objects giving off infrared radiation
C:reflects light visible to the human eyes
D:is similar to an ordinary digital camera

1.Some of the most commonly used medicines for high blood pressure are drugs called ACE inhibitors（抑制剂）.Doctors have given these drugs to patients for twenty-five years.A government study in the United States found that the use almost doubled between 1 995 and 2000.
2.Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy（怀孕）.The medicine can injure the bahy.ACE inhibitors,though,have been considered safe when taken during the first three months.But a new study has found that women who take these drugs early in their pregnancy still increase the risk of hirth disorders（先天性疾病）.Thestudyshowsthat,comparedtoothers,theirbabieswerealmostthreetimesaslikely to be horn with major problems.These included problems with thefo朋ation of the brain and nervous system and holes in the heart.
3.The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months.Researchers at Vanderbilt University in Tennessee and Boston University did the study. The New England Journal of Medicine published the results.The researchers studied the records of almost thirty thousand births between 1985 and 2000.Two hundred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies.Eighteen of the babies,or almost nine percent,had major disorders.
4.ACE inhibitors are often given to patients with diabetes（糖尿病）.But diabetes during pregnancy can result in birth defects（先天性缺陷）.So the study did not include any women known to be diabetic. ACE inhibitors suppress a protein called angiotensin-converting enzyme（血管紧张素转化酶）,or ACE. This enzyme produces a chemical in the body that makes blood passages narrow. The drugs increase the flow of blood,so pressure is reduced.
5.New drugs are tested on pregnant animals to see if they might cause birth defects in humans. But experts say these tests are not always dependable.The United States Food and Drug Administration helped pay for the study.The FDA says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure.
ACE is a risk factor to our body______.
A:that may cause our blood vessels to become more and more narrow
B:for pregnant women to take during their last six months of pregnancies
C:that their likelihood to suffer major problems is two times higher than other babies
D:with their doctors about how to treat their problems
E:because diabetes during pregnancy may sometimes lead to birth defects
F: though their mothers took ACE inhibitors during their first three months of pregnancies
