Healthy knees aren't the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos (细高跟鞋).  

"It takes a long time to feel the effects of knee osteoarthritis (骨关节炎) — and once you do, it is too ]ate," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School's department of physical medicine.

"I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said. "They are better for your feet than stiletto heels, but just as had for your knees."

 The idea that high heels are bad for your health isn't new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained (扭伤) ankles and back problems. 

But in 1998,Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage (软骨) surrounding the knee.

 The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.

 "This study confirms what we all intuitively (直觉地) know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.

Without the atmosphere there would be no weather, no wind, rain, snow, or clouds. Air is all around us; we live at the bottom of a great ocean of air. It is invisible, but we can feel it when it moves. There are miles of air above us, pressing down with great weight on the earth and everything on it. Because air presses down on us from all directions at the same time, and because we are able to bear (忍受) this weight, we do not seem to feel it. But scientists have proved that air has this weight, and that anything that has weight creates(产生) a force called pressure. As changes in air pressure take place, they, make air move.

Air is a gas that expands(膨胀) when heated, gets lighter, and moves upward. When air is cooled, it gets heavier, sinks close to the earth's surface, and flows like water in a great river. As warn air rises, cold air rushes in to take its place. 'Thus winds originate (起源). The winds that blow high above us are caused by the warmer air running away from colder air. The wind we feel near the earth's surface is the heavy colder air trying hard to catch the warmer air. Changes in temperature cause the air to move. And of course there are many changes, so air movements are taking place practically all the time.

The first paragraph mainly tells us the causes of

A．why we don't feel air　　　　　　　B．why atmosphere is important to us

C．why there is air surrounding us　　D．why there is air pressure

Air moves under such conditions that

A．there is air pressure              B．the air is heavy

C．air pressure doesn't remain the same all the time  D．air comes up and down

Which of the following pictures best tells the movements of warm air and cold air?

According to the passage, in same areas if farmers who grow grapes (葡萄) light fires in the early morning, that is because the farmers want to________________．

A．drive away warm air  B．prevent cold air from coming to harm their plants

C．cause more windD．stop warm air running away

The route from north to south is a general picture of Norwegian nature: thundering waterfalls, rushing mountain streams and roads that run along glaciers, after having gone through thick pine forests and coastal lakes and fiords(峡湾)．

The inner part of the country is very rugged and almost one third of it is covered with trees. Despite its northern latitude, the Norwegian weather is in fact maritime(海洋性的) and damp, because it is affected by the mitigating (调节)action of the warm Gulf Stream, coming from the Gulf of Mexico, which flows up the coast preventing the formation of sea ice.

Bergen, a port lying in the southeast of the country, is crowded with brightly colored houses, which belonged to German traders of the powerful Hanseatic League. Despite several fires, the area keeps the atmosphere of the “old port” and Commercial City from the Middle Ages. UNESCO (联合国教科文组织) recently declared it a World Heritage Site and included it in the list of monuments that are to be preserved.

There is a large park in the center of Bergen which is taken up almost completely by a large lake, around which, lie some of the main museums in the city.

The Hakonshallen, the most beautiful monument in the city, lies within the walls of Bergen's fortress. The great 13th century Gothic hall was built for the parties and the receptions in the days of the city's control over trade in the North Sea.

You get the best view over Bergen, the fiords and the surrounding pine－covered mountains from the belvedere(观景台). It's easy to admire Norwegians for their unique(独特的) way of respecting the nature!

From north to south, from Lapland to Oslo and Bergen, Norwegian people has proved, with time, that human beings, as the most advanced yet most vulnerable (脆弱的) in the great family of nature, can live in harmony (和谐) with all its other members.
