Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong reflection they produce. Because many of those large satellites have ceased to function, the proposal has recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since .

　　虽然与环绕地球轨道上的小块碎片的数目相比，环绕地球运转的大型人造卫星的数目小，但是大型卫星对于望远镜观测的干扰更严重，因为他们产生强烈的反射。因为许多这样的大型卫星已经停止运作，最近有建议提出将这些没有运作的大型卫星炸掉，以消除对于观测的干扰。然而这个建议是拙劣的，因为。

　　(A) many nonfunctioning satellites remain in orbit for years

　　(B) for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive

　　(C) there are no known previous instances of satellites’ having been exploded on purpose

　　(D) the only way to make telescope observations without any interference from debris in orbit is to use telescope launched into extremely high orbits around the Earth

　　(E) a great increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible

　　(A) 许多没有运作的卫星还持续在环绕地球的轨道上运转很多年

　　(B) 对于已经停止运作的卫星来说，在它们还在轨道上的时候对其进行修理是非常昂贵的

　　(C) 没有已知的将卫星故意炸掉的先例

　　(D) 想要进行没有任何来自轨道上碎片的干扰的望远镜观测的唯一方法是使用被发射到非常高的围绕地球轨道的望远镜

　　(E) 地球轨道中大量的小碎片会导致成群的反射现象，继而让获得任何有价值的望远镜观测变得不可能
