tells of freedom, success, and of the architecture of big american cities. because that is where it started: in the second half of the 19th century!welcome to a new era of kitchen interior designback then, a generation of successful american entrepreneurs dreamt of a new style of architecture to express their personal wealth. this dream was realized by young architects such as daniel burnham and stanford white. they all had studied at the cole des beaux-arts in paris. and they created a new style for architecture and interior design, named after the famous french art institute: beaux-arts. siematic beauxarts breaks and createsin fact it was not a new style at all, but a composition of styles from different periods and cultures. many world-famous structures such as the chicago art institute and the statue of liberty account for it. but what does that have to do with your kitchen?just as much as you want it to. because in the same way that the anti-conventional architects back then took the freedom to combine elements from different historical eras, today, you too can break the conventional rules of style and create something new: your own personal composition of your kitchen. for that, siematic beauxarts offers unique opportunities: a broad range of seemingly conflicting features that you combine to a harmonious design of your own. you can choose from menu of various forms, appealing colors, and precious materials, to create an environment that is much more than just a kitchen: a reflection of your personality.3.why did the beauxarts style attract american entrepreneurs?a.it helped display their money status.b.it was created by famous architects.c.it was named after a famous institute.d.it represented the 19th century urban culture.4.what is unique of siematic beauxarts?a.its designs are anti-conventional.b.its designs come from famous structures.c.its customers can enjoy their own composition.d.its customers can choose from various new styles.答案3.a4.ccfor months fish that live in dark caves in mexico go without food. they have gone far longerthousands of yearswithout light, evolving to lose their eyes and skin pigments (色素). now researchers have discovered these strange creatures have another oddity (古怪). they survive their food-scarce environment, and the fish have evolved extreme ways of turning nutrients into energy. these features create symptoms like large blood sugar swings that, in humans, are predictors of type diabetes.but in the fish these changes are adaptations, not a disease. these cave fish lead long and healthy lives.“understanding how the fish remain healthy in spite of these symptoms may lead to new approaches for treating diabetes in people,” says cliff tabin, a geneticist at harvard medical school. he and his colleagues are beginning to get clues about how cave fish survive the symptoms.in humans and other mammals, one of the first signs of type diabetes risk is poor control of glucose. this happens because cells resist insulin (胰岛素), the hormone that signals cells to take in glucose from the bloodstream. if the problems continue, they progress into full-blown diabetes. the illness kills 3.4 million people worldwide every year, but current treatments often do not work.the cave fish has, apparently, figured out another solution. the fish were washed from rivers into caves about a million years ago. it was a big change. rivers were full of food but caves have only what is washed in by seasonal floods.because the cave fish go many months without food, researchers assumed they evolved a metabolism (新陈代谢)that efficiently stores the calories in a similar way animals store fat before winter. to test that idea, they compared the cave fish with the river fish raised under the same conditions in the lab. they found the cave fish did store more visceral fat than the river fish. but the cave fish also had much larger, fatty livers, which resembled diabetes-linked fatty liver disease in humans. “but you dont see destruction of the liver in these guys,” tabin says. “its very curious.”cave fish researchers are now working to find out how the fish do it. “the only piece of total evidence is that the metabolic rate is lower in the cave fish than in their river fish relatives,” says alex keene of florida atlantic university. “there might be something about slow energy use in cells that protects against diabetes,” he says. “finding that will, like fishing, require some patience.”5.what interests researchers most in the cave fish is that .a.they have evolved to lose their eyes and skin pigmentsb.they have evolved ways of turning nutrients into energyc.they have experienced no symptoms of diabetes in humansd.the
