共用题干第二篇The IcemanOn a September day in 1991,two Germans were climbing the mountains between Austria and Italy.High up on a mountain pass,they found the body of a man lying on the ice.At that height(10,499 feet,or 3,200 meters),the ice is usually permanent,but 199 1 had been an especially warm year. The mountain ice had melted more than usual so the body had come to the surface.It was lying face downward. The skeleton（骨架）was in perfect condition , except for a wound in the head.There were still skin on the bones and the remains of some clothes.The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots.Nearby was a pair of gloves made of tree bark（树皮）and a holder for arrows.Who was this man?How and when had he died?Everybody had a different answer to these questions. Some people thought that it was from this century,perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area.A Swiss woman believed it might be her father,who had died in those mountains twenty years before and whose body had never been found.The scientists who rushed to look at the body thought it was probably much older,maybe even a thousand years old.With modern dating techniques,the scientists soon learned that the iceman was about 5,300 years old. Born in about 3300 B.C.,he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains.More recent evidence,however,tells a differentstory. A new kind of X-ray shows an arrowhead still stuck in his shoulder. "left only a tiny hole in his skin but it caused internal damage and bleeding. He certainly died from this wound,and not from the wound ontne back of his head. This means that he was probably in some kind of a battle. It might have been Part of alarger war, or he might have been fighting bandits.He might even have been a bandit himself.By studying his clothes and tools,scientists have already learned a great deal from the iceman about thetimes he lived in. We may never know the full story of how he died,but he has given us important clues totne history of those distant times.What can be inferred from Paragraph 2?A:The iceman was struck dead from behind.B:The iceman could have died from the wound in the head.C:The iceman was killed while working.D:The iceman lived a poor life.

问答题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. 1) 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).　　2) 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 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. 3) 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.　　4) 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 fold in much less than a second, propelled by a sort of antigravity. 5) 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.
