The Iceman

On 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 1991 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 ques-
tions.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 different story.A new kind of X-ray shows an arrowhead still stuck in his shoulder. It 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 on the back of his head.This means that he was probably in some kind of a battle.It might
have been part of a larger 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 the
times he lived in.We may never know the full story of how he died,but he has given us important clues to
the history of those distant times. All the following are assumptions once made about the iceman EXCEPT__________.
A.he was a Swiss woman's long-lost father
B.he came from Italy
C.he was a soldier in World War I
D.he was born about a thousand years ago
