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.
A:The waters of the ocean came from rain water. B:The ocean was formed from the lighter rock materials. C:The vast single ocean formed about 200 million years ago. D:The ocean covered the whole surface of the earth at very beginning.
We first think of the traditional or nuclear family. This is a two-generation family, the father and the mother and their own children. Most couples wanted to have four children, two boys, two girls.
Some nuclear families, however, may add one or more grandparents to come m live with them, that is three generations. This kind of family with grandparents, parents, and grandchildren is called an extended family. This family type was not very common during the later half of the twentieth century, but it’s becoming more common now as an elderly grandparent moves in to live with a son or daughter. This is more possible now that American homes have become larger. What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits.
Now, the fatherless or motherless family is one kind of what we call a single-parent family. In the fatherless family it’s just the mother and her children. As I said, this can be the result of the husband’s death, of an unmarried mother, of a separation or divorce. There are also a growing number of motherless families--where the father raises the children, for any of the same reasons. A motherless family may also be fatherless, but still a family with one adult. This is becoming more common in the big cities where a grandmother will raise her daughter’s children while the daughter goes elsewhere to work.
One other new kind of family is becoming increasingly more common. A single parent with one or more children will marry again. Perhaps the other parent is also a single parent. Together they will start what is called a blended family, which blends together or combines the children from two other families.
A:A blended family is formed by two single-parent families. B:A blended family is formed by a nuclear family and a grandparent. C:A blended family is formed by a nuclear family and grandparents. D:A blended family is formed by two fatherless families.
