Herve Bocherens, an evolutionary biologist at the University of Tubingen, Germany, says his colleagues think his research methods a little 'crude'. He dissolves 30,000-year-old animal bones in hydrochloric acid, which is strong enough to burn through metal, soaks the bone solution in lye, cooks it at about 200 degrees Fahrenheit and freeze-dries it until what's left is a speck of powder weighing less than one one-hundredth of an ounce. The method may be harsh, but the yield is precious – the biography of a cave bear as told through its chemical components. Bocherens is at the forefront of research on the bear, a European species that died out 25,000 years ago. People have been excavating cave bear remains for hundreds of years – in the Middle Ages, the massive skulls were attributed to dragons – but the past decade has seen a burst of discoveries about how the bears lived and why they became extinct. An abundance of bones has been found from Spain to Romania in caves where the animals once hibernated. 'Caves are good places to preserve bones, and cave bears had the good sense to die there,' Bocherens says.

答案：NOT GIVEN
原文定位：He dissolves 30,000-year-old animal bones in hydrochloric acid, which is strong enough to burn through metal, soaks the bone solution in lye, cooks it at about 200 degrees Fahrenheit and freeze-dries it until what's left is a speck of powder weighing less than one one-hundredth of an ounce
答案：plants
原文定位：After studying hundreds of bones from dozens of sites in Europe, Bocherens has found that cave bears ate mainly plants
答案：Europe
原文定位：This Ice Age shortened or eliminated growing seasons, and altered the distributions of plant species across Europe
同义替换：「changed vegetation growth」↔「shortened or eliminated growing seasons, and altered the distributions of plant species」，「in」↔「across」
答案：teeth
原文定位：Cave bears began to move from their old territories, according to a DNA analysis of teeth found near the Danube River
答案：hibernate
原文定位：As Neanderthals, and then a growing population of modern humans moved into the caves of Europe, cave bears had fewer safe places to hibernate
同义替换：「reduced opportunities」↔「had fewer safe places」
答案：NOT GIVEN
原文定位：Bocherens is at the forefront of research on the bear, a European species that died out 25,000 years ago
答案：TRUE
原文定位：Bocherens is at the forefront of research on the bear, a European species that died out 25,000 years ago
同义替换：「extinct」↔「died out」
答案：TRUE
原文定位：People have been excavating cave bear remains for hundreds of years – in the Middle Ages, the massive skulls were attributed to dragons
同义替换：「At one time」↔「in the Middle Ages」，「remains of bears」↔「the massive skulls」，「thought」↔「were attributed to」
答案：FALSE
原文定位：Males weighed up to 1,500 pounds, 50 per cent more than the largest modern grizzly bears
同义替换：「similar in size」↔「50 per cent more than」
答案：NOT GIVEN
原文定位：Initially cave bears shared the continent of Europe more than 100,000 years ago with Neanderthals, a primitive species of humans. Modern humans arrived in Europe about 40,000 years ago, and were soon aware of the bears
答案：skeletons
原文定位：The painters weren't the cave's only occupants;the floor is covered with 150 cave bear skeletons, and its soft clay still holds paw prints
同义替换：「Over a hundred」↔「150」
答案：skull
原文定位：Most dramatically, a cave bear skull was perched on a stone slab in the center of one chamber, placed deliberately by some long-gone cave inhabitant
同义替换：「prominent position」↔「in the center of」
答案：shelter
原文定位：Long ago, as shown by the bones and tools that archaeologists have found, cave bears and human beings sought shelter here from winter weather
同义替换：「provided」↔「sought」
