问题    In addition to his theory of color, Newton developed a theory of how light travels, This is known as the corpuscular theory of light, meaning that light travels as a series of tiny bits rather than in continuing waves. Newton sent his writings to the Royal Society, where they were given to a committee led by Hooke. Since the corpuscular theory was different from Ids own theory, Hooke attacked the paper. Soon others started to argue, and Hooke was supported by a scientist from Holland, Christian Huygens. At one time, Newton was so unhappy with tile whole affair that he decided never again to publish any of Ids works.
   The bitter argument continued over the years that followed. At first, Hooke and Huygens received most of the support, Later, after Newton had changed ids mind and let Ids work on gravity be published, he became so famous that things changed. Now people believed Newton could do nothing wrong, and for a hundred years they followed his theory. Then, in the early part of the 19th century, the experiments of a French scientist, Augustin Fresnel, showed that light could be explained best by a wave theory. So the scientists changed sides again, saying that Newton’s ideas had delayed scientific progress for a hundred years.
   Strangely enough, rite presently-accepted theory of light combines some of the ideas of both theories. This is known as the quantum theory and results from the work of such 20th century scientists as Albert Einstein and Max Planck. The quantum theory assumes that light is given off as separate " packages" of energy. Each "package" travels out in a fixed pattern or wave form. These "packages" of light, or quanta of energy, as they are called, are given off at such a rapid rate that there is no great gap between them.
   The quantum theory seems to explain the actions of light better than either of the two earlier theories. However, for many purposes, the wave theory is good enough. So it is used most often to explain light. But who is to say that new experiments and other scientists of our own time or in the future may not provide an even better theory? There is certainly still much work to be done with light and color. [br] Which of the following statements is TRUE according to the passage?
选项 A、Hooke and Huygens received the support from many scientists as Hooke was a leader of the Royal Society.
B、People changed their opinions of Newton simply because he had the theory of gravity published.
C、Tile quantum theory seems better than other theories so it is used most often to explain how light travels.
D、The quantum theory seems to be nearest in idea to that of Fresnel and Newton combined.
答案 D
解析 文章第三段第一句指出“Strangely enough，the presently-accepted theory of light combines some of the ideas of both theories．”而这个“the presently-accepted theory of light”就是“the quantum theory”，据此就可断定[D]正确。
