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．
60．How many organizations are involved in the two studies?
A．Three． B．Four． C．Five． D．Six．
61．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．
62．Why do running shoes increase the risk of injuries to runners?
A．They could create stress．
B．They’re too big and heavy．
C．They can affect the way the runners land．
D．Their heels can soften landings．
63．How did the researchers do the two studies?
A．By practising． B．By comparing．
C．By questioning． D．By reasoning．

The wedding took place in a Birmingham hotel．The bride and her father arrived in a new black American sport car．Her father looked nervous and uncomfortable in front of the cameras．The bride wore a silk wedding dress．She smiled nervously at the waiting photographers and went to a room on the first floor where she met her future husband for the very first time．
Carla Germaine and Greg Cordell were the winners of a radio station’s competition．The aim of the competition was to find two strangers prepared to marry without having met each other．Miss Germaine, 23, is a model．Mr．Cordell, 27, is a TV salesman．They were among the two hundred people who entered a peculiar “experiment” organized by BMRB radio in Birmingham, England, Greg, and Carla were among eight finalists who were interviewed live on a radio．They took a lie detector（测谎仪） test and the station also spoke to their friends and family about their personalities．The competition judges include an astrologer（占星家） who declared that they were suited．
The couple celebrated their wedding with a wedding breakfast and a party for 100 guests in the evening, but not everyone shared their joy．Miss Germaine’s mother looked anxious throughout the wedding and Mr．Cordell’s parents are reported to be less than delighted．
Organizations, including the marriage guidance Service Relate, have criticized the marriage．As one person put it, “We have enough problems getting young people to take marriage seriously without this．Marriage should always be about love．”

Sitting in a dark movie theater with your friends and a tub of
buttery popcorn sounds like a perfect way to spend a Saturday night
—and it could be, if you are willing to share your popcorn with the
entire row of moviegoers around you.
A review of the nutritional contents of movie-theater popcorn reveals
an alarming amount of fat, salt and calories in even the smallest sizes.
The study, mad by Dr. Nestle from the Center for Science in the Public
Interest, checked popcorn from three movie theater chains and detailed
The contents of all parts offered.
A large tub of popcorn at Regal Cinemas, for example, holds 20 cups of popcorn and has 1,200 calories, 980 milligrams of sodium（钠）and 60 grams of saturated（饱和）fat.
Not so hungry? The medium size popcorn, which comes in a bag, contains the same amount as the large. And even the small, at 1l cups, delivers 670 calories 550 milligranis of sodium 24 grams of saturated fat.
The findings may surprise those who choose popcorn at the concession stand（货摊） because they believe it is a relatively healthy snack. In fact, plain air-popped popcorn is low in calories and free of saturated fat. Movie theater popcorn, however, is popcorn, however, is popped in oil — often coconut oil, which is 90 percent saturated fat. Add salt to the enormous portions（部分）,and your once-healthy snack turns into a health killer.
Even the “healthiest” sample of popcorn tested, a small size from AMC containing 6 cups of popcorn, had 370 calories, enough to share with a friend, eating one grain at a time to make it last the length of a movie.
The third movie theater chain tested. Cinemark, is slightly better than its competitors because it pops its popcorn in non-hydrogenated canola oil instead of coconut oil. Cinemark’s large tub contains 17 cups of popcorn with 910 calories and 4 grams of saturated fat, as well as up to 1,500 milligrams of sodium — nearly enough for the entire day.
One way to make your popcorn healthier? Ask the theater to pop a portion without salt. Two of the movie theaters that had their popcorn tested said they would oblige such a request. The best way to make your movie snack healthier, however, would be to skip the popcorn — and the concession stand — altogether.
“You could share a tub of popcorn with 10 friends.” Dr. Nestle said. “Or, what a concept, watch the movie without eating anything.”
