What happens inside the skull of a soccer pla...

What happens inside the skull of a soccer player who repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.

For the study, researchers at the Albert Einstein College of Medicine in New York selected 34adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.

Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can't be seen during most scans.

According to the data they presented at a Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.

This pattern of white matter loss is "similar to those seen in traumatic (外伤的) brain injury", like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.

The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.

1.The passage is most probably a______.

A．news report                           B．research report

C．story for soccer players                   D．text for doctors

2.In which way can we find the structural changes in the brain?

3.From the passage we can conclude that frequent heading may have_____.

A．significant effect on brain                 B．little effect on one's brain

C．nothing to do with the brain injury          D．one's memory improved

4.What is likely to be the cause of memory loss?

A．Playing soccer frequently.                 B．Tests of their memory.

C．White matter loss.                       D．Information processing.

5.The underlined word "fumbling" is closest in meaning to______.

Our series The Genius Behind will take you inside the minds of people who are making the impossible possible. Whether it is designing the fastest ever land vehicle, helping the blind to see or creating space history, success relies levels of knowledge to new heights . What can we learn about genius from minds? Based on the people and the projects outlined in the series, we’ve come up with five lessons.

Lesson one: New challenges require new ways of thinking

Bloodhound SSC aims to be the first vehicle to break the 1,000 mph barrier. One of the key challenge has been to design the wheels. Thinking twice, Mark Chapman, chief engineer decided to change the way they were trying to solve problems and came up with a wheel design, part car, part jet fighter and part spaceship, which would hold together and was strong enough.

Lesson two: Let evidence share your opinion

Geophysicists widely believed that water on Earth originated from comets. But by studying rocks, Steven Jacobsen discovered water hidden inside, suggesting that the oceans gradually made its way out of the planet’s interior many centuries ago. “Unfortunately, I had a pretty hard time convincing others,” he admits. Only time can tell whether the new theories are true.

Lesson three: It really is 99% efforts

Sheila Nirenberg at Cornell University is trying to develop a new prosthetic device(假肢器官)for treating blindness. “Sometimes I’m exhausted and I get burnt out,” she adds. “But then I get an email from somebody saying that they can’t see their own children’s faces, and it is like, ‘How can I possibly complain? Once I thought of this, I couldn’t eat, I couldn’t sleep—all I wanted to do was work’. It gives me the energy to just go back and keep doing it.”

Lesson four: The answer isn’t always what you expect

Sylvia Earle has spent decades trying to see the ocean with new eyes. Her “dream machine” is a submarine that could take scientists all the way to the bottom of the deepest ocean floor what sort of material could best withstand the types of pressure y would encounter thousands of miles below the ocean surface?” It could be steel, it could be titanium, it could be some sort of ceramic, or some kind of aluminium system,” says Earle. “But glass is the best choice.”

Lesson five: A little luck goes a long way

It was considered as one of the biggest success stories in the history of space exploration—20 years of planning ended earlier this year with the Philae lander landing safely Comet 67P over 300 million miles(480 million kilometers)away from Earth, though Philae’s anchoring harpoons(锚定鱼叉)didn’t fire as planned.

As a matter of fact, genius is difficult to define. “Genius is a funny word,” says Nirenberg. “I just sort of ignore it and just go on with life. You just do what you do regardless of whatever label’s attached to you. I don’t know really how else to explain it.
