Though having failed several times, Tim, who didn’t give up his dream, _____ made his dream come true.

LONDON—Here’s a new warning from health experts：Sitting is deadly.

Scientists are increasingly warning that sitting for long periods—even if you also exercise regularly—could be bad for your health.And it doesn’t matter where the sitting takes place—at the office，at school，in the car or before a computer or TV—just the overall number of hours it occurs.Several studies suggest people who spend most of their days sitting are more likely to be fat，have a heart attack or even die.

In an editorial published this week in the British Journal of Sports Medicine，Elin Ekblom?Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting.

While health officials have issued guidelines recommending minimum amounts of physical activity，they haven’t suggested people try to limit how much time they spend in a seated position.

“After four hours of sitting，the body starts to send harmful signals，”said Ekblom?Bak.She explained that genes regulating(调节) the amount of glucose(葡萄糖) and fat in the body start to shut down.

Even for people who exercise，spending long periods of time sitting at a desk is still harmful.Tim Armstrong，a physical activity expert at the World Health Organization，said people who exercise every day—but still spend a lot of time sitting—might get more benefit if that exercise was spread across the day，rather than in a single bout(一回)．

Still，in a study published in 2009 that tracked more than 17,000 Canadians for about a dozen years，researchers found people who sat more had a higher death risk，whether or not they exercised.

“We don’t have enough evidence yet to say how much sitting is bad，” said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge，who led the Canadian study.“But it seems the more you can get up and interrupt this sedentary behavior，the better.”

Figures from a U．S. survey in 2003?2004 found Americans spend more than half their time sitting，from working at their desks to sitting in cars.

Experts said more research is needed to figure out just how much sitting is dangerous，and what might be possible to offset those effects.

“People should keep exercising because that has a lot of benefits，” Ekblom?Bak said.“But when they’re in the office，they should try to interrupt sitting as often as possible，” she said.

　　Build the highway and watch the town grow.At first a few shops appear and maybe a restaurant.Then a hotel opens. Eventually new house are built. A village is born.
　　This is also how the virtual world has developed. Think of the Internet as the road carrying information between two computers.Think of the World Wide Web as the village. At first it is just a place on the virtual road where travelers meet. More travelers come bringing new kinds of information. New travelers come bringing new kinds of information.New villages are started.
　　Every willage has a founder.Tim Berners-Lee is the man who wrote the software programme that led to the foundation of the Word Wide Web.How did he get the idea? He tells us on his own web site. "One of the things computers were not able to do was store in formation from different sources. The dream behind the Web is of a common space in which we communicate by sharing information."
　　In 1991 his programmmes were placed on to the Internet.Everyone was welcome to use them.
　　Tim Berners-Lee could have followed the Microsoft route by forming a company to sell the programmes he invented. Or he could have joined another company. But in his view the Web is a language,not a pproduct. Charging a gee for using his programmes would have slowed the growth of the Web.And other companies would make similar products to compete. Instead of one World Wide Web there would be several smaller Webs. Each would use incompatible (不相容的) software. They Web is valuable because it uses a common computer language to reach people and share information. Competing webs would lose this value.Imagine if somebody sent you a bill every time you spoke a world of English.
　　In 1994 Tim Berners-Lee formed the World Wide Web Consortium,or W3C.More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone, no matter what their equipment or solftware,can work equally on the Web.
　　"The Web can help people to understand the way that others live and love. It helps us understand the humanity of people," he says.

　　　C.help people to form a web site
　　　D.let people share all kinds of information
　　70.According to the text,the disadvantage of competing webs is that they would ______.

Heading back to the room for dinner and a hot shower may sound like the act of a tired tourist ,but in a traditional Japanese inn ─ or ryokan ─ those activities can be as interesting as anything along the sightseeing trail.“People going looking for a sort of nostalgic(怀旧的),old-fashioned ,and traditional view of Japanese life will find it most easily in a ryokan,”said Peter Grilli, the president of Japan Society of Boston, Massachusetts.

Many ryokans sprang up in the 17th century to put up feudal lords traveling along the Tokaido highway to Edo(now Tokyo). Today tourists looking for a taste of the country’s historic lifestyle find varying levels of understated elegance in ryokans throughout the country.

A typical stay starts with a greeting from the inn’s staff and a change from street shoes into slippers .An attendant leads guests to their rooms, where slippers are removed before walking on the rice-straw flooring, called tatami. Walking slowly along behind a kimonoclad（身穿和服的）attendant on the creaky wood floors of Fukuzumiro ryokan,s hallways is like stepping back in time. The inn was established in 1890 by a former samurai（武士）.

Tim Paterson ,33, a banker living in Tokyo, has stayed at several ryokans. This New Zealand native leaves after a recent stay at Fukuzumiro. “I think it’s quite good mixing culture with history and not just going to see it ,but living in it, staying in it,”he said. Sliding glass doors line the inn’s rural hallways, bringing in the sound of tricking water and the quietness of the stone and tree-filled courtyards outside.

Skateboarding has become one of several non-traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line（滚轮） skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
"Our children and youth are becoming unhealthy and obese," says Johnson. "Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest."
Some schools don't allow skateboarding because they say it is dangerous. Tim, however, argues that regular practice eliminates a great deal of the danger. "We teach students how to do it and how to do it safely," he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed. ”says education expert Richard Savor from College in Portland.
Skateboarding inspires kids not to give up in learning difficult skills. "It's natural for kids to want to learn and get better at things," adds Tim. "When it comes to skateboarding, they'll try a trick hundreds of times before they succeed." That same effort could be made in schoolwork.
Eric Brown agrees that skateboarding requires kids to stop saying a task is too hard for them. "A baby will attempt to walk 600 to 900 times before he or she is successful," says Eric, "We tell students that they shouldn't say 'I can't do it' unless they've tried 600 to 900 times.
72. Skateboarding is introduced into American schools to ______________.
A. encourage students to compete bravely in competition  
B. teach students how to deal with risk.
C. prevent students suffering from heart disease later in life.
D. help students form the habit of doing sports
73. The underlined word "eliminates" in Paragraph 4 probably means ______________.
A. reduces.         B. increases         C. adds        D. brings
74. What life lesson do kids learn from skateboarding?
A. To succeed in life you have to learn skateboarding.
B. You will succeed in life if you don't give up.
C. Only after failing 600 to 900 times can you succeed.
D. There is no hard work after learning skateboarding well.
75. What would be the best title for the passage?
A. The dangerous PE            B. Skills of skateboarding.  C. The new PE.      D. The change of PE.
