问题     Research has shown that excessive noise damages people’s hearing. In fact many young people now suffer from deafness from regularly going to discos where the level of noise is so high that they have to shout to make themselves heard. Unfortunately, in spite of modern technology, noise is very much part of our modern world planes flying overhead, traffic thundering along busy roads, television, portable radios, all produce noise to which we have become so accustomed that we hardly notice it. In fact people going on country holidays have been known to complain that it is too quiet. They actually miss the noise they are used to in their daily lives. The problem is that noise, though it does not necessarily cause deafness, causes anxiety and this can in the long run prove harmful. However, the decision about more or less noise cannot be left to the scientists alone. It is up to us to decide what kind of world we want to live in.

选项 A、the loss of listening ability
B、the loss of sight
C、excessive excitement
D、the loss of health

答案D

解析 根据上一句的意义:Edmund Halley注意到了1456年、1531年、1607年和1683彗星出现时轨迹很相似。那么这里的动词应该表达Edmund Halley由他发现的相似性得出结论,[A]decided意为“决定”;[B]thought意为“认为”;[C] concluded意为“得出结论”;[D]imagined意为“想象”。因此答案为[C]。
