Even as the tallest animals on Earth, giraffes can be easy to overlook. Despite being a favorite in zoos, until recently almost nobody studied giraffes in the wild. ‘When I first became interested in giraffes in 2008 and started looking through the scientific literature, I was really surprised to see how little had been done,’ said Megan Strauss, an animal researcher at the University of Minnesota, USA. All that is changing fast, as a growing number of researchers seek to understand the biology and complex behavior of this graceful giant in its native habitat.

答案:TRUE
原文定位:Until recently almost nobody studied giraffes in the wild;All that is changing fast, as a growing number of researchers seek to understand the biology and complex behavior of this graceful giant in its native habitat
同义替换:「natural environment」↔「native habitat」,「has increased lately」↔「a growing number of」
答案:birth
原文定位:The growth of the neck largely takes place during early childhood, as giraffe mothers would have a difficult time giving birth to young with longer necks
同义替换:「length develops in childhood」↔「takes place during early childhood」,「easier」↔「would have a difficult time」
答案:veins
原文定位:The outside of a giraffe's veins are extremely thick, to prevent blood leaking into surrounding tissue
同义替换:「extra strong」↔「extremely thick」,「keep blood from spilling」↔「prevent blood leaking」,「other」↔「surrounding」
答案:heart
原文定位:Researchers were also surprised to find that a giraffe does not have an unusually large heart
同义替换:「normal size」↔「does not have an unusually large」,「for such a large animal」↔「giraffe」
答案:distance
原文定位:This is because signals from the nerves travel at about the same speed in giraffes as in rats or other mammals. Given the greater distance they have to travel in the giraffe to reach the brain, it is possible the giraffe faces real challenges in reacting quickly to a rock beneath its hoof or a bite to its ankle
同义替换:「slower reaction time」↔「faces real challenges in reacting quickly」
答案:NOT GIVEN
原文定位:Despite being a favorite in zoos, until recently almost nobody studied giraffes in the wild. ‘When I first became interested in giraffes in 2008 and started looking through the scientific literature, I was really surprised to see how little had been done,’ said Megan Strauss
答案:FALSE
原文定位:Giraffes, found throughout sub-Saharan Africa, are currently classified as a single species with up to nine subspecies that differ by features like head shape and whether the fur on their legs is plain or patterned. The giraffe is not yet listed as endangered, but researchers point to evidence that in the past 15 years, the population has fallen some 40 percent
同义替换:「The number of」↔「the population」
答案:NOT GIVEN
原文定位:Female giraffes can live 20 years or more, and it makes sense they might rely on each other for clues to the best feeding grounds
同义替换:「live longer」↔「can live 20 years or more」
答案:TRUE
原文定位:Giraffe calves are extremely vulnerable to predators, and though mothers will fight valiantly to keep their young alive - kicking forward and backward — half of all calves are killed in their first year of life
同义替换:「use their legs」↔「kicking forward and backward」,「defend their young」↔「fight valiantly to keep their young alive」
答案:FALSE
原文定位:Recent observations show young bulls, when left on their own, mimicking their elders: head held high and neck puffed out. But should a dominant older bull come into view, the younger males instantly try to make themselves look small and innocent
同义替换:「more powerful males」↔「a dominant older bull」,「in the presence of」↔「come into view」
答案:TRUE
原文定位:The younger bulls have reason to fear their elders. Clashes have been witnessed between adults when each bull repeatedly ‘necks’ the other, using his massive neck to slam his head against his rival
同义替换:「Male giraffes」↔「bull」,「observed」↔「witnessed」,「fighting」↔「slam his head against his rival」
答案:camouflage
原文定位:The coat has dark patches separated by light hair, which serves as camouflage, allowing them to blend in with the light and shade patterns of the acacia trees from which they feed
同义替换:「provides」↔「serves as」,「when standing near trees」↔「blend in with the light and shade patterns of the acacia trees」
答案:hands
原文定位:In addition, a giraffe’s extraordinary mouth has lips and tongue that can together grasp a branch and then pluck away the leaves while avoiding thorns, almost as humans would grab with their hands
同义替换:「to get leaves」↔「pluck away the leaves」
