这三段话中间的语法重点难点,
"Before my condition was diagnosed,I was very bored with life," Hawking says today,speaking from his wheelchair through a computerized voice synthesizer.The doctors' grim prognosis made him determined to get the most from a life he had previously taken for granted.
"But I didn't die," Hawking notes dryly.Instead,as his physical condition worsened,Hawking's reputation in scientific circles grew,as if to demonstrate the theory of mind over matter.Hawking himself acknowledges his disease as being a crucial factor in focusing his attention on what turned out to be his real strength:theoretical research.Hawking specializes in theoretical cosmology,a branch of science that seeks ultimate answers to big questions; Why has the universe happened,and what are the laws that govern it?His main work has been on black holes and the origin and expansion of the universe.He currently holds the Cambridge University professorship once held by Sir Isaac Newton.
The smartest man in the world is not immune to the depression that can accompany severe disabilities.But Hawking says:"I soon realized that the rest of the world won't want to know you if you're bitter or angry.You have to be positive if you're to get much sympathy or help." He goes on:"Nowadays,muscle power is obsolete.What we need is mind power—and disabled people are as good at that as anyone else."

第一段重点“be bored with” 是厌烦 be determined to do指决定做某事 “taken for granted是"理所当然"的意思
第二段重点as if好像acknowledges.as 承认.是.turned out to be 结果是specializes in 专门从事He currently holds the Cambridge University professorship once held by Sir Isaac Newton.是个省略句,once 前需加which was
第三段重点be immune to 对.有免疫力disabled people are as good at that as anyone else其中that 指mind powe
