Passage Three
Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form. a crust of rock that was many miles thick.
Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.
In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.
The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.

阅读下列短文，然后根据短文的内容从 55～57 小题的四个选择项中选出最佳的一项。
B
Scientists have searched for many years for a method to tell whether a volcano（火山）explosion will be small or large. Now，four scientists say they have discovered something in lava（熔岩）that will help do this. They did the research on Mount Unzen on the southern Japanese island of Kyushu.
Mount Unzen exploded in November，1990. Since then，more explosions have killed 43 people and destroyed the homes of more than 2，000 others. The volcano is still active today.
The scientists say the lava of the volcano contains high level of an element（成份），which is a sign of the presence of the lava from deep in the earth，not from the surface. They say it shows that the lava coming directly from inside the earth is connected with huge explosions instead of smaller ones.
The scientists examined the lava from 18 explosions of Mount Unzen that took place during many thousands of years. They also studied the lava from other volcanoes in the area that are older than Mount Unzen. The lava studied came from both large and small explosions. The scientists found that large explosions contained more of the element than small ones. The scientists say if they had known this two years earlier，they could have warned the people living in the area near Mount Unzen and saved many lives.
第 55 题 From the passage we learn that Mount Unzen is the name of ______.
A．a huge volcano explosion
B．a Japanese island
C．an active volcano
D．a kind of lava
A.the more
