As a fellow at Cambridge, Stephen Hawking calculated that the Big Bang, which gave birth to the universe, must have created tiny black holes, each about the size of a proton(质子)but with the mass of a mountain. Then upsetting the universal belief that nothing, not even light, can escape from a black hole, he used the quantum(量子)theory to demonstrate that these miniholes emit radiation. Other scientists eventually conceded that he was correct, and the black hole emissions are now known as Hawking radiation.
Engrossed as Hawking is with his work, ALS(神经肌肉萎缩症)is simply not that important to him. He certainly does not dwell on his physical disability. His comments are often filled with humor; he enjoys socializing with his students and colleagues, attends rock concerts and sometimes takes to the dance floor at discos. But he can be stubborn, rough and quick to anger, terminating a conversation by spinning around and rolling off, sometimes running one of his wheels over the toes of an offender. Hawking can also be wrong. In 1985, for example, he self-assertively proclaimed that when and if the universe stopped expanding and began to contract, time would reverse and everything that had ever happened would be rerun in re- verse. Eighteen months later, he sheepishly admitted his mistake. Earlier after trashing another scientist’s notion that the 19th century theory of thermodynamics(热力学)could be applied to blackhole theory, he took back and began applying it himself.
Without his wife Jane, Hawking has always emphasized, his career might never have soared. She married him shortly after he was diagnosed with ALS, fully aware of the dreadful, progressive nature of the disease, giving him hope and the will to carry on with his studies.
They had three children in the early stages of their marriage, and later, as he became increasingly incapacitated, she devoted herself to caring for his every need.
After years of apparently harmonious marriage, however, serious disagreements began appearing. As awards poured in for Stephen, Jane -- competent and intelligent herself -- began to resent living in his shadow. Deeply religious, she was also offended by his apparent atheism(无神论). Particularly galling(侮辱)to her was his concept, expressed first before the Pope at a scientific meeting at the Vatican, that the universe might be completely self-contained, having no boundary or edge, no beginning or end. If that were true, he asked provocatively, "What place, then, for a creator?" Still, friends were shocked in 1990 when Hawking abruptly ended their 25-year marriage, moving in with one of his nurses.
According to the passage, black holes ______.
选项
A、include protons
B、oppose the quantum theory
C、stop anything from escaping
D、give off radiation
答案
D
解析
根据题干blackholes定位到原文第一段第二句话:推翻丁普遍认为没有什么能逃脱黑洞的观点,他用量子理论来解释这些小洞能释放射线。give off意思是“释放”,和原文emit意思相同,所以选D)。 A)是对原文的曲解;B)与原文内容相反;C)是以前人们的观点。
