each claims to be the world's busiest airport. O'Hare may be the world's busiest airport. Or it may be only the second busiest. But everything about it is big.

The Federal Aviation Administration says more than nine hundred thirty thousand flights traveled through O'Hare last year. During that time, more than sixty-nine million passengers passed through O'Hare.

Most of these people were waiting for connecting flights. As they waited, they could shop at many airport stores. They could eat at airport cafes. They could exercise at a health club or do office work in a business-support center. They could take their children to a flight museum or visit the airport's religious center.

The huge O'Hare Airport of today is very different from its beginning. It started as a military air base and factory in the nineteen forties. The center produced planes for World War Ⅱ. Later, the airport was named for Navy pilot Edward O'Hare. He was killed in an action during the war after being honored with medals for bravery.

Big as O'Hare airport is today, however, it is not big enough. Too many airplanes crowd the runways where they take off and land. Delays and cancellations interfere with air traffic across the country. Officials say sixty-five percent of the flights at O'Hare were delayed during the first seven months of this year. This was the worst record among the nation's major airports.

To improve the situation, the governor of Illinois signed the O'Hare Modernization Act last year. The Act calls for building another runway. Existing runways would be moved and extended. More buildings are planned. The project will cost more than six-and-one-half-thousand-million dollars. When all that is completed in the next eight years, busy O'Hare Airport can get even busier.

You are going to read a text about the approaches to creating championship, followed by a list of examples. Choose the best example.

(41) What do you need in order to be a record breaker？

Sports experts agree that the single most important factor in creating a champion is genetic make-up, the possession of genes that impart an innate ability to stride leap, burn energy efficiently or suck lots of oxygen from the air. "The great athletes are genuine statistical outliers...physiological freaks," says sports scientist Craig Sharp of Brunel University in Middlesex, UK.

(42) How will we find or create the next generation of champion athletes？

The most likely way is to widen our search to find someone with a genetic makeup that allows him or her to surpass other athletes. When East African runners began competing internationally, for example, it became apparent that their light frame. make them uniquely economical in their use of energy.

(43) Have we reached the limit of human performance？

No, but records are being broken by ever narrower margins. When statisticians plot how the best performance in a given event changes over time, they see the graph leveling off. And the shorter the event, the smaller are the slivers of time being shaved off. So al though Paula Radcliffe has sliced whole seconds off the marathon world record, sprinters are improving by mere hundredths of a second.

(44) Will we ever reach an absolute limit？

Theoretically, an absolute time to how far or fast the human body can go does, but "where it is we don't know," says Millar. Perhaps the only way we can recognize the ultimate performance will be retrospectively, after a record has stood for years.

(45) In future, will athletes simply test their limits in new ways？

As records become harder and harder to break, we may start comparing athletes by other standards, such as the number of gold medals or their performance over time. Lance Armstrong's six consecutive wins in the Tour de France, for example, may never be surpassed. "The elite might be defined by how many times they win", says Millar.

A. Athletes might also invent new sports to test themselves. The emergence of the triathlon in the 1970s was fuelled by runners, swimmers and cyclists looking for a new challenge; it made its debut as an Olympic event in 2000.

B. Once scientists have identified the genes that confer a genetic advantage in sport, athletes might also be screened to pick out the ones with most genetic potential. "There are all sorts of people out there, and we don't know what they can do", says exercise and sports scientist Carl Foster of the University of Wisconsin in La Crosse. Because the rewards are growing and competition is becoming more intense, athletes are being driven more and more towards drugs to gain the edge. Experts predict that the next generation of champions will include many doped ones. They are particularly fearful of "gene doping" in which athletes boost the performance of key genes.

C. Psychology is vital. Athletes need enormous focus and drive to win. Many people think that the main barrier to breaking the four-minute mile was a psychological one: once Roger Bannister did it in 1954, several others clocked sub-four-minute times shortly afterwards. Sometimes breaking a record involves taking a risk in an event, such as breaking from the pack with a full lap to go, and that takes a certain state.

D. Not every sport can be accurately measured, of course. Running and jumping can be quantified with stick or stopwatch, but football and tennis performances are much harder to gauge.

E. On top of this, however, training and technique are vital. They allow athletes to sculpt muscles, for example, so that they burn less energy while achieving the same speeds as others.
