Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine. Sometimes they wore running shoes. Other times they ran barefoot.
Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of the American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
64. How many organizations are involved in the two studies?
A. Three. B. Four. C. Five. D. Six.
65. Why do running shoes increase the risk of injuries to runners?
A. They create more stress.
B. They’re too big and heavy.
C. They can affect the way the runners run.
D. Their heels can soften landings.
66. What can we learn from the text?。
A. Most running shoes are designed improperly.
B. The design of high heels is better than that of running shoes.
C. No one will run with running shoes in the future.
D. Both of the studies are done in America.
67. How did the researchers do the two studies?
A. By practising. B. By comparing.
C. By questioning. D. By reasoning.

Only one of the ancient wonders of the world still survives — now history lovers are being invited to choose a new list of seven.
An original list of nearly 200 sites nominated by the public was narrowed to 21 by the organizers and experts, including the former director general of Unesco Professor Federico Mayor.
The vote is organized by a non-profit Swiss Foundation called New 7 Wonders which specializes in the preservation (保存), restoration and promotion of monuments (纪念碑), and the results will be announced on July 7, 2009, in Lisbon.
About 20 million votes have already been lodged (提出) including many from India, for the Tai Mahal; China, for the Great Wall; Britain, for the Stonehenge; the only British landmark and from Peru, for Machu Picchu, the fortress city of the Local.
The other original seven wonders of the ancient world were the Hanging Gardens of Babylon; the Statue of Zeus at Olympia; the Temple of Artemis at Ephesus; the Mausoleum at Halicarnassus; the Colossus of Rhodes and the Lighthouse of Alexandria.
Tia Viering, spokeswoman for New 7 Wonders, said: “Apart from the Pyramids, the seven ancient wonders of the world no longer exist.”
The only standard for the new list is that the landmarks were built or discovered before 2000.

When she looked ahead, Florence Chadwick saw nothing but a solid wall of fog. Her body was unfeeling. She had been swimming for nearly sixteen hours.
Already she was the first woman to swim the English Channel in both directions. Now, at age 34, her goal was to become the first woman to swim from Catalina Island to the California coast.
On that Fourth of July morning in 1952, the sea was like an ice bath and the fog was so dense that she could hardly see her support boats. Sharks came toward her lone figure, only to be driven away by rifle shots. Against the cold water of the sea, she struggled on — hour after hour — while millions watched on national television.
Alongside Florence in one of the boats, her mother and her trainer offered encouragement. They told her it wasn’t much farther. But all she could see was fog. They urged her not to quit. She never had . . . until then. With only a half mile to go, she asked to be pulled out.
Still warming her chilled body several hours later, she told a reporter, “Look, I’m not excusing myself, but if I could have seen land I might have made it.” It was not fatigue (疲劳) or even the cold water that defeated her. It was the fog. She was unable to see her goal.
Two months later, she tried again. This time, despite the same dense fog, she swam with her faith ready and her goal clearly pictured in her mind. She knew that somewhere behind that fog was land and this time she made it! Florence Chadwick became the first woman to swim across the Catalina Channel, eclipsing (让……黯然失色) the men’s record by two hours!

A. She couldn’t swim with the dense fog.
B. She could hardly see her support boats.
C. She was all worn out.
D. She couldn’t see the land ahead.
58. It can be inferred from the text that_______.
A. weather has little effect on swimmers
B. knowing one’s goal is very important
C. Florence had great desire to break the men’s record

As school starts again, there's so much more for an American parent to nag （唠叨）about, like homework，bedtime and lost hours on the Internet.
But in the age of digital childhood，Jacky Longwell, 45 , of McLean, Virginia, often text – messages what she once told her children by mouth: Be nice to your brother; walk the dog; remember your reading.
This is the world of the modern family, in which even reminding children to do something has become electronic.
There are changes in how parents nag and in what they nag about and in how often of their nagging.
With technology," you nag more, and you are a little bit more precise （其体的）with your nagging,” said Reginald Black, 46, of Woodbridge. Virginia.
For many young people electronic nagging is part of the experience of growing up.
Charles Flowers, 17, a senior at St. John’s College High School in Washington, says his mother reminds him about everything from laundry, being on time to baseball practice and mowing the lawn by text.
When she uses capitals he knows she’s serious: GET HOME!
Some say technology has made nagging less annoying. Jacky Longwell thinks texts are less emotional than spoken messages and less likely to be resisted by teenagers.
“It’s not as painful for them to hear it by text. It becomes grouped with the friendly communication.” she said. “They can’t hear the nagging.”
She thinks a good way to do it is to mix friendliness with nagging. A parent can always start by saying hello.
Not all parents like the new electronic nagging. Joyce Bouchard, 51, a mother of four in Fairfax, Virginia , texts her 14 - year - old son but says that for many things-chores, homework-the old - fashioned way works better. Nagging by text has risks. She notes: “I always think, if you’re texting them something and they’re with their friends, they are getting a big laugh out of it.”
