[不定项选择题]共用题干 第二篇

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 peiianerIt,but 1991 had been an especially warm year. The mountain ice had
melted more than usual and 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 was still skin on the hones 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 ahd 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 proba-
bly a hunter who had died in 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 almost 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 EXCEFF__________.
A.he was a soldier in World War Ⅰ
B.he was a Swiss woman's long-lost father
C.he was born about a thousand years ago
D.he came from Italy
