1 . Grizzly bears, which may grow to about 2.5 m long and weigh over 400 kg, occupy a conflicted corner of the American psyche — we revere (敬畏) them even as they give us frightening dreams. Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see, and their answer is often the same: a grizzly bear.

“Grizzly bears are re-occupying large areas of their former range,” says bear biologist Chris Servheen. As grizzly bears expand their range into places where they haven’t been seen in a century or more, they’re increasingly being sighted by humans.

The western half of the US was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans. By the early 1970s, after centuries of cruel and continuous hunting by settlers, 600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies. In 1975, grizzlies were listed under the Endangered Species Act.

Today, there are about 2,000 or more grizzly bears in the US. Their recovery has been so successful that the US Fish and Wildlife Service has twice attempted to delist grizzlies, which would loosen legal protections and allow them to be hunted. Both efforts were overturned due to lawsuits from conservation groups. For now, grizzlies remain listed.

Obviously, if precautions (预防) aren’t taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food. If people remove food and attractants from their yards and campsites, grizzlies will typically pass by without trouble. Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away. “Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits,” says James Jonkel, longtime biologist who manages bears in and around Missoula.

2 . As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.

“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.

Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic (无氧) exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.

“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didn’t change, he says.

“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all.”

Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.

1. What does Levine want to explain by mentioning the rubber band?

A．The right way of exercising.	B．The causes of a heart attack.
C．The difficulty of keeping fit.	D．The aging process of the heart.

2. In which aspect were the two groups different in terms of research design?

A．Diet plan.	B．Professional background.
C．Exercise type.	D．Previous physical condition.

3. What does Levine’s research find?

A．Middle-aged hearts get younger with aerobic exercise.

B．High-intensity exercise is more suitable for the young.

C．It is never too late for people to start taking exercise.

D．The more exercise we do, the stronger our hearts get.

4. What does Dr. Nieca Goldberg suggest?

A．Making use of the findings.	B．Interviewing the study participants.
C．Conducting further research.	D．Clarifying the purpose of the study.

4 . The Biggest Stadiums in the World

People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.

These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.

For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.

All these stadiums are still functional, still open and still hosting the biggest events in world sport.

·Rungrado 1st of May Stadium, Pyongyang D.P.R. Korea. Capacity: 150,000. Opened: May 1,1989.

·Michigan Stadium, Ann Arbor, Michigan, U. S. Capacity: 107,601. Opened: October 1, 1927.

5 . When I was 9, we packed up our home in Los Angeles and arrived at Heathrow, London on a gray January morning. Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.

Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don’t worry about it. Once, when trying a certain trick on the beam(横杆), I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “ Safe! Safe! Safe!” And that’s what mattered—landing tricks, being a good skater.

When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I’d given it up.

When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I’ve traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch the skaters. Weaving(穿梭)among the kids who rushed by on their boards, I found my way to the beam. Then a rail—thin teenager, in a baggy white T—shirt, skidded(滑)up to the beam. He sat next to me. He seemed not to notice the man next to him. But soon I caught a few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man. Safe.”

“Yeah,” I said. “Safe.”

6 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.

Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "

For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.

A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.

These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.

"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.

Maria and Peter lived in a coastal city. The greatest pleasure in summer for them was to swim at their local beach after school. But one day they started to lose their enthusiasm for swimming in the waters. More often than not, they would find plastic bags thrown on the beach. Worse sill, as they swam in the water, some plastic bags would float around them and even stick to their legs when they walked to the shore.

They were upset and decided something needed to be done to stop the beautiful sea becoming consumed by waste.One weekend,Maria and Peter brought a big bag to the beach and determined to clean it up. Sweat streamed down from their forehead while they bent down and picked up the plastic bags. To their disappointment, after a day’s hard work, there were still many plastic bags lying on the beach or floating in the water. Going home with aching legs and arms, Maria and Peter were almost defeated by a strong sense of failure.

That night over dinner with their parents, the pair ate silently. Noticing their low spirits, Mother asked gently, “You two looked so down. What happened?”Exchanging glances with Peter, Maria replied in a low voice,“It’s those annoying plastic bags. We tried to clean up but it was just impossible.”Understanding the pair’s disappointment, their father patted them on the back and comforted,”Well, it’s really hard for just two of you to fix such a big problem.”“Just two of us.”complained Maria and Peter, looking at each other.Suddenly, an idea lashed through their minds, their eyes shining with excitement.“Yes,that’s the point! We should make more people aware of the problem and encourage them to take action!” the pair said in chorus.
