Going Back to Its Birthplace
No sporting event takes hold of the world'S attention and imagination like the Olympic
Games The football world Cup fascinates fans in Europe and South America；baseball's World Series is required viewing in North America；and the world table Tennis Championships attracts the most interest in Asia.
But the Olympics belong to the whole world.Now，after travelling to 17 countries over 108years，the summer Games are returning to Athens，the place where the first modern Olympicswas held.
Participation in the Games is looked on not only as an achievement，but also as an honour，The 16 days between August 13 and 29 will see a record 202 countries compete，up fromSydney's 199. Afghanistan is back，having been banned from Sydney because the Talibangovernment didn't let women do sports.There is also a place for newcomers East Timer and Kiribati A total of 10.500 athletes will compete in 28 sports，watched by 5 3 million ticket-paying viewers as well as a television audience of 4 billion.
Athens is to use its rich history and culture to make the Olympics as special as possible.The Games will open with cycling events which start in front of the Parthenon and Acropolis monuments.The final event will be a historic men's marathon following the 0rjgihal route l"un by Phidippides in 490 BC to bring news of victory over the Persians.
The ancient stadium at Olympia.first used for the Games nearly three centuries ago，will stage the shot put competitions.And the Panathenian Stadium，where the first modern Olympics was held，is to host the archery （射箭）events.
If the well-known ancient sites deliver a great sense of history to the Games.the 39 newvenues add a modem touch to the city of Athens The main Olympic stadium.with a giant glassand steel roof，is the landmark（标志）building of the Olympics.
"We believe that we will organize a'magical'Games."said Athens 2004 President Gianna Angelopoulos-Daskalaki."Our history with the Olympic Gaines goes back nearly 3，000 years，and Athens 2004 could be the best ever."

Even Intelligent People Can Fail
1 The striking thing about the innovators who succeeded in making our modern world is how often they failed.Turn on a light，take a photograph，watch TV，search the web，jet across the Pacific Ocean，talk on a cellphone（手机）。The innovators who left us these things had to find the way to success through a maze（错综复杂）of wrong tarns.
2 we have just celebrated the 125th anniversary of American innovator Thomas Edison's success in heating a thin line to white.hot heat for 14 hours in his lab in New Jersey，US.He did mat on October 22.1879.and followed up a month later by keeping a thread of common cardboard alight（点亮着的）in an airless space for 45 hours.Three years later he went on t0 light up half a square mile of downtown Manhattan，even though only one of the six power plants in his design worked when he tamed it on，on September 4，1882.
3 "Many of 1ife's failures."the supreme innovator said."are people who did not realize how close they were to Success when they gave up"Before that magical moment in October 1879. Edison had worked out no fewer than 3，000 theories about electric light，but in only two cases did his experiments work.
4 No one likes failure.but the smart innovators 1earn from it Mark Gumz，the head of the camera maker Olympus America Inc，attributes some of the company's successes in technology to understanding failure.His popular phrase is："Y0n only fail when you quit."
5 Over two centuries.the most common quality of the innovators has been persistence That is another way of saying they had the emotional ability to keep up what they were doing.Walt Disney，the founder of Disneyland，was so broke after a succession of financial failures that he was left shoeless in his office because he could not afford the US$1.50 to get his shoes from me
repair shop Pioneering car maker Henry F0rd failed with one company and was forced out of another before he developed the Model T car.
6 Failure is harder to bear in today's open.accelerated world.Hardly any innovation works the first time.But an impatient society and the media want instant success.When American music and movie master David Geffen had a difficult time.a critic said nastily that the only
difference between Geffen Records(Geffen's company)and the Titanic(the ship that went down)
was that the Titanic had better music Actually，it wasn't.After four years of losses，Geffen had 80 many hits（成功的作品）he could afford a ship as big as the Titanic an to himself.
More Than a Ride to School
The National Education Association claims."The school bus is a mirror Of the community."They further add that，unfortunately，what appears on the exterior（外部）does not always reflect the reality of a chosen community.They are right.and sometimes it reflects more！Just ask Liesl Denson Riding the school bus has been more than a ride to school for Liesl.
Bruce Hardy.sch001 bus driver for Althouse Bus Company has been Liesl's bus driver since kindergarten Last year when Liesl's family moved to Parkesburg，knowing her bus went by her new residence，she requested to ride the same bus This year Liesl is a senior and will enjoy her last year riding the bus.She says."It's been a great ride so far！My bus driver is so c001 and has always been a good friend and a good listener.
Sometimes when you're a child adults do not think that what you have to say is important.Mr.Hardy always listens to what you have to say and makes you feel important."Her friends AshleyBatista and Amanda Wolfc agree.
Brace Hardy has been making Octorara students feel special since 1975.This year he will celebrate 30 years working for Althouse Bus Transportation.Company President.Larry A1thouse acknowledges Bruce Hardy's outstanding record."You do not come by employees 1ike Bruce these days；he has never missed a day of work and has a perfect driving record.Recognized in 2000 by the Pennsylvania School Bus Association for driving 350，000 accident free miles，Hardy's reputation is made further evident through the relationships he has made with the students that ride his bus''A1thouse further added."Althouse Bus Transportation was established 70 years ago and has been providing quality transportation ever since MY grandfather started the business with one bus.Althouse Bus Transportation is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come.''
Three generations of business is not all the company has enjoyed.Thanks to出ivers like Bruce Hardy，they have been building relationships through generations.Liesl's mother CaroI also enjoys fond memories of riding Bruce Hardy's bus to the Octorara Sch001 District.

Don't Count on Dung
Conservationists（自然保护主义者）may be miscalculating the numbers of the threatened animals such as elephants.say African and American researchers.The error occurs because of a flaw in the way they estimate animal numbers from the piles of dung（粪）the creatures leave behind.
The mistake could 1ead researchers to think that there are twice as many elephants as there really are in some regions according to Andrew Plumptre of the Wildlife Conservation Society(wcs) in New York
Biologist Katy Payne of Cornell University in Ithaca，New York，agrees.''We really need to know elephant numbers and the evidence that we have is quite indirect，"says Payne，who electronically tracks elephants Counting elephants from planes is impossible in the vast rainforests of Central Africa.So researchers often estimate elephant numbers by counting dung piles in a given area.They also need to know the rate at which dung decays Because it's extremely difficult to determine these rates.however，researchers counting elephants in one region tend to rely on standard decay rates established elsewhere.
But researchers at the WCS have found that this decay rate varies from region to region
depending on the climate and environment Using the wrong values can lead the census astray
He and his colleague Anthony Chifu Nchanji studied decaying elephant dung in the forests of Cameroon They found that the dung decayed between 55 and 65 per cent more slowly than the dung in the rainforests of neighbouring Gabon.If researchers use decay rates from Gabon to count elephants in Cameroon，they would probably find more elephants than are actually around.
This could mean estimates in Cameroon are at least twice as high as those derived from
decay rates calculated locally，says Plumptre"However accurate your dung density estimate
might be.the decay rate can severely affect the result"
Plumptre also says that the dung-pile census should be carried out over a region similar in size to an elephant's natural range The usual technique of monitoring only small，protected areas distorts numbers because elephants move in and out of these regions，he says"If the elephant population increases within the protected area，you can not determine whether 1t is a real increase or whether it is due to elephants moving in because they are being poached（入侵偷猎）outside."
Plumptre says that similar problems may also affect other animal census studies that rely on indirect evidence such as nests，tracks or burrows（地洞）
36 The word"threatened"in the first sentence of the first paragraph could be best replaced by
37 Why do researchers estimate elephant numbers in an area by counting dung piles?
A Because elephants are difficult to catch
B Because it is not possible to count elephants from a plane.
C Because it is not possible to keep track of elephants.
D Because elephants are shy animals
38 Piles of dung can't be relied upon when it comes to estimating elephant numbers because
A they are different in size
B they scatter an over the region.
C they are different in decay rate.
D they are different in quality.
39 According to Plumptre，the region over which a dung-pile census is carried out should be
A small enough
B well protected.
C carefully monitored.
D large enough

More Than Just Money
When Patricia Rochester decided to go back to school after ten years as a staff nurse at oronto Western Hospital.her employer not only cheered her on.but also Paid her tuition and gave her a day off with pay every week to study.Throughout her years at the hospital，Rochester has also taken workshops on everything from coaching peers to career development--courses that she believes have helped her advance at work."I'm now head of the mentoring（指导）program for new hires.students and staff nurses."she says."There's a lot of room for personal improvement here."
Perhaps as important，Rochester says her employer supports and values her work.''If you put in overtime."the nurse points Out."you get your meals-they'11 order in pizza or Greek food or Chinese."And if staffers feel stiff and stressed from too many hours on the ward.they can call for a flee 15-minute shoulder-and-neck massage（按摩）or even sign up for an eight-week
evening course on meditation skills and stress-relief.If that's not enough，employees can take advantage of five family days a year that can be used if the kids come down with the flu or an aging parent needs ferrying to an important doctor's appointment And they have access to a range of perks（好处）such as special rates on hotel rooms，drugstore purchases，and scholarships for employees'children.
You might wonder how an organization can provide such resources and still survive.But University Health Network is one of a number of progressive employers in Canada that have discovered that investing in staff is good business.
If such initiatives help companies cut down on turnover（人员更替）alone，they're well worthwhile.says Prem Benimadhu，a vice-president at the Conference Board of Canada.It costs anywhere frmn$3.300 to rehire support staff，an average$13，300 for technical staff and a whopping（巨资）$43，000 for an executive position，according to one study of Conference Board members Innovative initiatives help companies attract talented employees，cut down on sick days （which cost Canadian businesses an estimated$17 billion a year，or an average of$3，550 perEmployee）and keep employees more interested in their work.With the substantial talent shortage that already exists in Canada and the prospect of mass retirement over the next five years-as many as 50 or 60 percent in some sectors-Benimadhu says that intelligent employers are putting a renewed focus on the people who work for them.

Read with Greater Speed
Do you have difficulty reading in class?If so,a special reading program that helps match sounds with letters could speed up your brain.
At least one out of every five elementary school students in the US has trouble learning t0 read，even when the students are good at other subjects.____（46）
Researchers from Yale University,US,studied a group of children from New York and Connecticut State.As part of the study，37 struggling readers received special tutoring Every day,instructors worked with them on recognizing how written letters represent units of sound called phonemes（音素）____（47）.By the end of the school year，these children could read faster than before.They also made fewer mistakes，and understood more of what they read than they could earlier in the year，As part of their study，the researchers used a special machine to take action photos of the tudents'brains.
_(48)This is the same part of the brain that becomes active when good readers ead.This activated brain area appears to include a structure that helps people recognize familiar written words quickly.In lower level readers，this structure remains inactive.
A year later,the brain structure was still working hard in the students who had gone through he special tutoring，and they continued to do well in reading tests.___（49）
However，some researchers still doubt the study_____（50）
A Many adults are interested in matching sounds with letters
B The students also practiced reading aloud and spelling
C The biggest challenge for many of these kids，scientists say，is matching sounds with letters.
D Another group in the study who went through a more traditional reading program didn't how the same progress.
The pictures showed all increase in activity in the back of the brain on the left side
F They believe that reading without making any noise or linking words to sounds is moreefficient.
