Stephen Hawking was definitely one of them. Hawking was a theoretical physicist whose early work on black holes __1__ how scientists think about the nature of the universe. Lawrence Krauss, a theoretical physicist from Arizona State University and a friend and colleague of Hawking's, says that at a young age. Hawking __2__ something “truly remarkable”. Krauss says before Hawking , physicists thought that the large gravity of a black hole __3__ everything in and nothing could escape. But by combining quantum mechanics ( 量子力学) and the theory of relativity, Hawking showed something and changed everything about the way we think about gravity. Krauss says Hawking pointed out a(n) __4__ problem in the way physicists understand our world 一 a problem that Krauss says has yet to be resolved. But his fame wasn’t just a(n) __5__ of his research. Hawking, who had a rare disease that made it impossible for him to move or speak, was also a popular public____6____ and best-selling author. When he came to scientific conferences , the audience focused their attention on him. And it wasn’t just the scientists but the general public as well who showed great __7__ for him. His popular book about his work, A Brief History of Time, was a best-seller. But he agreed that that book was probably the least-read, most-bought book ever. This showed Hawking's sense of humor. That sense of humor, along with his fame, __8__ Hawking to appear on The Simpsons several times as well as on a number of other popular shows. Toward the end of his life, Hawking’s disease left him almost (瘫痪的) .It look an enormous __9__ for Hawking to communicate, using the tiny movements he could make to control a computer. It’s tempting to say that Hawking achieved his fame in spite of his __10__ challenges.
