46、rs 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 oldBorn in about 3300 BC，he lived during the Br

47、onze 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

48、damage and bleedingHe almost certainly died from this wound，and not from the wound oil the back of his headThis means that he was probably in some kind of battleIt may have been part oi a large war，or he may have beenfightiing banditsHe may even have been a bandit himself By studying his clothes and

49、 tools，scientists have already learned a great deal from the Iceman about the times he lived inwe may never know the full story of how he died，but he has given usimportant clues to the history of those distant times 36The body of the iceman was found in the mountains mainly because_ Ahe was lying on
