Unit 5 Nelson Mandela-a modern hero Ⅰ.阅读理解 [2017·河北唐山摸底] With the press of a button，a person with severe spinal cord (脊柱) injury is able to walk again，thanks to the Walking Assistive Exoskeleton Robot(WAER)． Powered suits that could help paralyzed (瘫痪) people walk and others lift and carry heavy loads with ease have been a dream since late 19th century.But they can realize their dreams in the 21st century. The 20-kilogram robot has four battery-powered motors that can run for up to three hours.Inventor Wu Chenghua，from Taiwans Industrial Technology Research Institute，says it has successfully been in tests on 12 patients.“We have learned from our research process that patients whose injuries are below the fourth chest joint(关节) are able to use our robot to stand，walk and sit down，”he said. Since walking contributes to muscle exercise，Wu says patients receive some additional benefits.“In the clinical process，we would check their bone mineral density (密度)，and we found that the bone mineral densities of these patients had been improved，” he said.Wu says his exoskeleton may be available for consumers by 2018. Meanwhile，baggage handlers at Tokyos Haneda Airport will soon start testing a similar robot，developed by the Japanese firm Cyberdyne.The battery-powered robot weighs only 3 kilograms，but can lift a heavy object.The machine monitors the movements，says Yoshiyuki Sankai，the developer and CEO of Cyberdyne. “This robot suit monitors the signal，from the human nerve (神经) system to support the waists movement，”Sankai said.“It self-adjusts the level support to reduce the load on the human waist，light and smart.We believe that it will change the life of paralyzed people in many ways and have a promising future.” 1．With the help of WAER，patients will probably________. A．recover from spinal cord injury B．improve their bone mineral density C．walk as fast as normal people D．monitor their waists movement 2．What can we learn about the invention of Wu Chenghua from the passage? A
