ROME: The legend of Leonardo da Vinci is covered in mystery: How did he die? Are the remains buried in a French castle really those of the master? Was the Mona Lisa a selfportrait in disguise (伪装) ?
A group of Italian scientists believe the key to solving those puzzles lies with the remains,and they say they are seeking permission to dig up the body to conduct carbon and DNA testing.
If the skull is undamaged,the scientists can go to the heart of a question that has fascinated scholars and the public for centuries; the identity of Mona Lisa. Recreating a virtual (虚拟的) and then physical reconstruction of Leonardo's face,they can compare it with the smiling face in the painting.
Leonardo moved to France at the invitation of King Francis I,who named him "first painter to the king". He spent the last three years of his life there,and died in 1519 at age 67. The artist's original burial place,the palace church of Saint Florentine,was destroyed during the French Revolution and remains that are believed to be his were eventually reburied in the Saint-Hubert Chapel near the castle.
"The Amboise tomb is a symbolic tomb; it's a big question mark," said Alessandro Vezzosi,the director of a museum dedicated to his hometown of Vinci. Vezzosi said that investigating the tomb could help identify the artist's bones with certainty and solve other questions,such as the cause of his death. He said he asked to open the tomb in 2004 to study the remains,but the Am?boise Castle turned him down.

Most of us are used to seasons. Each year,spring follows winter,which follows autumn,which follows summer,which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years ago,the planet was much colder than it is now. During that time the temperature also changed a lot? with periods of warming and cooling. Ice mel?ted during the warm periods,which made sea levels rise. Water froze again during the cold periods.
A new study fromSwitzerlandmakes it clear where ice sheets (冰川) melted during the ice age. It now seems that the ice melted at both ends of the earth,rather than just in either northern or southern regions.
This surprised the researchers from the University of Bern. Scientists have long assumed that most of the ice that melted was in the northern hemi?sphere (半球) during the 30,000-year long ice age. That belief was held because the north pole is surrounded by land,while the south pole is surrounded by the Antarctic ocean. It is easier for ice sheets to grow on land. If surrounded by sea the ice can easily just slip into the ocean instead of building up.
The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the northern hemisphere that ice melted,there would have been a bigger impact (影响) on ocean currents and sea tempera?tures than what actually happened. Studies suggest that melting just in the southern hemisphere would have been impossible,too. The only reasonable conclusion,the scientists could make,was that ice melted equally in the north and the south.
It is still a mystery as to what caused the temperature changes that caused the ice to melt.
1. The north pole is surrounded by land,while the south pole is surrounded by the Antarctic ocean. So scientists thought that.
A. most of the ice melted in the northern hemisphere
B. most of the ice melted in the southern hemisphere
C. the north pole is colder than the south pole
D. the south pole is colder than the north pole
2. We can infer from the passage .
A. the ice can easily just slip into the ocean
B. volcanoes caused the ice to melt
C. melting just in the northern hemisphere would have been impossible
D. researchers often use the computer models to help their research work
3. The scientists are not sure .
A. how long the ice age lasted
B. where ice sheets melted during the ice age
C. what caused the temperature changes
D. what the earth is made up of
4. Which of the following is the best title for the passage?
A. A computer model
B. Studies show ice melted equally in the north and the south during the ice age
C. Most of the ice melted in the northern hemisphere during the 30 ,000-year long ice age
D. A survey result
