Passage Two
What’s hot for 2007 among the very rich A ＄ 7.3 million diamond ring. A trip to Tanzania to hunt wild animals. Oh, and income inequality,
Sure, some leftish billionaires like George Soros have been railing against income inequality for years. But increasingly, centrist and right-wing billionaires are starting to worry about income inequality and the fate of the middle class.
In December, Mortimer Zuckerman wrote a column in U.S. News & World Report, which he owns. "Our nation’s core bargain with the middle class is disintegrating," lamented (哀叹) the 117th-riehest main in America. "Most of our economic gains have gone to people at the very top of the income ladder. Average income for a household of people of working age, by contrast, has fallen five years in a row." He noted that "Tens of millions of Americans live in fear that a major health problem can reduce them to bankruptcy."A. The prices of imported goods will inevitably soar beyond control.
B. The investors will have to make great efforts to re-allocate capital.
C. The wealthy will attempt to buy foreign companies across borders.

[不定项选择题]共用题干
The Family
The structure of a family takes different forms around the world and even in the same society.The family's form changes as it adapts to changing social and economic influences.
Until recently,the most common form in North America was the nuclear family,consisting of a married couple with their minor children.The nuclear family is an independent unit,It must be prepared to fend for itself.Individual family members strongly depend on one another.There is little help from outside the family in emergencies.Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so.In North America,the elderly often do not live with the family；they live in retirement communities and nursing homes.
There are many parallels between the nuclear family in industrial societies,such as
North America,and of families in societies such as that of the Inuits,who live in harsh environments.The nuclear family structure is well adapted to a life of mobility.In harsh conditions,mobility allows the family to hunt for food.For North Americans,the hunt for jobs and improved social status also requires mobility.
The nuclear family was not always the North American standard.In a more agrarian time,the small nuclear family was usually part of a larger extended family.This might have included grandparents,mother and father,brothers and sisters,uncles,aunts,and cousins.
In North America today,there is a dramatic rise in the number of single-parent households.
Twice as many households in the United States are headed by divorced,separated,or nevermarried individuals as are comprised of nuclear families.The structure of the family,not just in North America,but throughout the world,continues to change as it adapts to changing conditions.

A.money
B.readiness to move
C.organization
D.skill
