People in the United States in the nineteenth century were haunted by the prospect that unprecedented change in the nation's economy would bring social chaos. In the years following 1820 after several decades of relative stability the economy entered a period of sustained and extremely rapid growth that continued to the end of the nineteenth century. Accompanying that growth was a structural change that featured increasing economic diversification and a gradual shift in the nation's labor force from agriculture to manufacturing and other nonagricultural pursuits.

Although the birth rate continued to decline from its high level of the eighteenth and early nineteenth centuries the population roughly doubled every generation during the rest of the nineteenth century. As the population grew, its make up also changed. Massive waves of immigration brought new ethnic groups into the country. Geographic and social mobility — downward as well as upward — touched almost everyone. Local studies indicate that nearly three quarters of the population in the North and South, in the emerging cities — the Northeast and in the restless rural counties of the West — changed their residence each decade. As a consequence, historian David Donald has written, "Social atomization affected every segment of society," and it seemed to many people that "all the recognized values of orderly civilization were gradually being eroded.

Rapid industrialization and increased geographic mobility in the nineteenth century had special implications for women because these changes tended to magnify social distinctions. As the roles of men and women played in society became more rigidly defined, so did the roles they played in the home. In the context of extreme competitiveness and dizzying social change, the household lost many of its earlier functions and the home came to serve as a haven of tranquility and order. As the size of families decreased, the roles of husband and wife became more clearly differentiated than ever before. In the middle class especially, men participated in the productive economy while women ruled the home and served as the custodians of civility and culture. The intimacy of marriage that was common in earlier periods was rent, and a gulf that at times seemed unbridgeable was created between husbands and wives.

What does the passage mainly discuss?

A．The economic development of the United States in the eighteenth century.

B．Ways in which economic development led to social changes in the United States.

C．Population growth in the western United States.

D．The increasing availability of industrial jobs for women in the United States.

The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, Beautiful Inside My Head Forever, at Sotheby's in London on September 15th 2008. All but two pieces sold, fetching more than ￡70m, a record for a sale by a single artist. It was a last victory. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brothers, filed for bankruptcy.

The world art market had already been losing momentum for a while after rising bewilderingly since 2003. At its peak in 2007 it was worth some $65 billion, reckons Clare McAndrew, founder of Arts Economics , a research firm—double the figure five years earlier. Since then it may have come down to $50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries.

In the weeks and months that followed Mr Hirst's sale, spending of any sort became deeply unfashionable. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector, they were down by nearly 90% in the year to November 2008. Within weeks the world's two biggest auction houses, Sotheby's and Christie's, had to pay out nearly $200m in guarantees to clients who had placed works for sale with them.

The current downturn in the art market is the worst since the Japanese stopped buying Impressionists at the end of 1989. This time experts reckon that prices are about 40% down on their peak on average, though some have been far more fluctuant. But Edward Dolman, Christie's chief executive, says: " I'm pretty confident we're at the bottom. "

What makes this slump different from the last, he says, is that there are still buyers in the market. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds—death, debt and divorce—still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return.

In the first paragraph, Damien Hirst's sale was referred to as "a last victory" because_________.

A．the art market had witnessed a succession of victories

B．the auctioneer finally got the two pieces at the highest bids

C．Beautiful Inside My Head Forever won over all masterpieces

D．it was successfully made just before the world financial crisis

Ruth Simmons joined Goldman Sachs's board as an outside director in January 2000; a year later she became president of Brown University. For the rest of the decade she apparently managed both roles without attracting much criticism. But by the end of 2009 Ms. Simmons was under fire for having sat on Goldman's compensation committee; how could she have let those enormous bonus payouts pass unremarked? By February the next year Ms. Simmons had left the board. The position was just taking up too much time, she said.

Outside directors are supposed to serve as helpful, yet less biased, advisers on a firm's board. Having made their wealth and their reputations elsewhere, they presumably have enough independence to disagree with the chief executive's proposals. If the sky, and the share price, is falling, outside directors should be able to give advice based on having weathered their own crises.

The researchers from Ohio University used a database that covered more than 10, 000 firms and more than 64, 000 different directors between 1989 and 2004. Then they simply checked which directors stayed from one proxy statement to the next. The most likely reason for departing a board was age, so the researchers concentrated on those "surprise" disappearances by directors under the age of 70. They found that after a surprise departure, the probability that the company will subsequently have to restate earnings increases by nearly 20% . The likelihood of being named in a federal class-action lawsuit also increases, and the stock is likely to perform. worse. The effect tended to be larger for larger firms. Although a correlation between them leaving and subsequent bad performance at the firm is suggestive, it does not mean that such directors are always jumping off a sinking ship. Often they "trade up, " leaving riskier, smaller firms for larger and more stable firms.

But the researchers believe that outside directors have an easier time of avoiding a blow to their reputations if they leave a firm before bad news breaks, even if a review of history shows they were on the board at the time any wrongdoing occurred. Firms who want to keep their outside directors through tough times may have to create incentives. Otherwise outside directors will follow the example of Ms. Simmons, once again very popular on campus.

According to Paragraph 1, Ms. Simmons was criticized for_________.

A．gaining excessive profits

B．failing to fulfill her duty

C．refusing to make compromises

D．leaving the board in tough times

There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (state and statistics come from the same Latin root, status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censuses—all of which led to modem descriptive statistics. From the influence of the father came modem inferentical statistics, which is based squarely on theories of probability.

Descriptive statistics involves tabulating, depicting, and describing collections of data. These data may be either quantitative, such as measures of height, intelligence, or grade level—variables that are characterized by an underlying continuum or the data may represent qualitative variable, such as sex, college major, or personality type.

Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is tool for describing or summarizing or reducing to comprehensible form. the properties of an otherwise unwieldy mass of data.

Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child; the proportion for the entire district could be estimated fairly accurately from a sample of as few as 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from knowledge of the characteristics of only a sample of the population.

Which of the following are counting and describing associated with?

A．Descriptive statistics

B．Unknown variables

C．Qualitative changes

D．Inferential statistics
