44、was the man?How and when had he died?Everybody had a different answer to these questionsSome 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 this areaA Swiss woman who believed it might be her father,

45、who had died in those mountains twenty years before and whose body had never been foundThe scientists who rushed to look at the body thought it was probably much older,maybe even a thousand years old With modem dating techniques,the scientists soon learned that the iceman was about 5,300 years oldBo

46、rn in about 3300 BC,he lived during the Bronze Age in EuropeAt first scientists thought he was probably a hunter who had died from an accident in the high mountainsMore recent evidence,however,tells a different storyA new kind of X-ray shows an arrowhead still stuck in his shoulderIt left only a tiny hole in his skin,but it caused internal damage and bleedin
