问题 关于宇宙起源的科学发现
——1998年英译汉及详解
They were, by far, the largest and most distant objects that scientists had ever detected: a strip of enormous cosmic clouds some 15 billion light years from earth.【F1】But even more important, it was the farthest that scientists had been able to look into the past, for what they were seeing were the patterns and structures that existed 15 billion years ago. That was just about the moment that the universe was born. What the researchers found was at once both amazing and expected; the US National Aeronautics and Space Administration’s Cosmic Background Explorer satellite—Cobe—had discovered landmark evidence that the universe did in fact begin with the primeval explosion that has become known as the Big Bang(the theory that the universe originated in an explosion from a single mass of energy).
【F2】The existence of the giant clouds was virtually required for the Big Bang, first put forward in the 1920s, to maintain its reign as the dominant explanation of the cosmos. According to the theory, the universe burst into being as a submicroscopic, unimaginable dense knot of pure energy that flew outward in all directions, emitting radiation as it went, condensing into particles and then into atoms of gas. Over billions of years, the gas was compressed by gravity into galaxies, stars, plants and eventually, even humans.
Cobe is designed to see just the biggest structures, but astronomers would like to see much smaller hot spots as well, the seeds of local objects like clusters and superclusters of galaxies. They shouldn’t have long to wait.【F3】Astrophysicists working with ground based detectors at the South Pole and balloon borne instruments are closing in on such structures, and may report their findings soon.
【F4】If the small hot spots look as expected, that will be a triumph for yet another scientific idea, a refinement of the Big Bang called the inflationary universe theory. Inflation says that very early on, the universe expanded in size by more than a trillion trillion trillion trillion fold in much less than a second, propelled by a sort of antigravity.【F5】Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary particle physics, and many astrophysicists have been convinced for the better part of a decade that it is true.
【F3】
选项
答案天体物理学家使用南极陆基探测器和球载仪器，正在越来越近地观测这些结构，也许不久会报告他们的观测结果。
解析 本句考查的重点是：现在分词短语作定语和句子成分的转化。 该句是由and连接并列谓语的简单句，其主干是Astrophysicists…are closing in on…and may report theirfindings，working with…and…instruments…是现在分词作后置定语，修饰主语astrophysicists，实际上是表示astrophysicists所用的研究工具，所以不一定要译成定语，可译为“用…”；at the South Pole修饰groundbased detectors。
