(l)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. (2)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 makeup 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 in 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." (3)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.

Cristian Danescu-Niculescu-Mizil and colleagues at Cornell University have taught a computer to identify classic quotes with an accuracy【C2】______ that of mankind. It means computers might one day help film writers test their latest classic lines. The Cornell team collected quotes from the Internet Movie Database, which contains a list of lines flagged by users as deserving to be【C3】______. The context in which a line is uttered can make a quote more notable, so as a control, the team paired each classic quote with an ordinary one from the【C4】______ context.

The computer analysed the pairs of quotes—around 2,200 in total—for language【C5】______, unusual words, and word combinations.

"The phrases contain【C7】______ combinations of words, but at the same time they have a sentence structure that is common, so they are easy to use," says Danescu-Niculescu-Mizil. The analysis also showed that classic lines often have a(n)【C8】______: they can be widely used because they don't contain words that tie them to a specific context.

More Shun National College Entrance Exam to Go Abroad Education Ministry figures show that about 10 percent of, or more than 1 million, high school graduates did not take the gaokao in each of the past five years. About 20 percent of high school graduates in some top schools in cities such as Beijing and Shanghai have chosen to study overseas, according to the ministry. This resulted in the Chinese student population abroad rising to 400,000 in 2013, and the figure is continuing to increase, the ministry said. Special classes for students applying to universities overseas have become common at schools nationwide to help them prepare for the TOEFL and SAT US admissions tests. Agencies that help students who want to study abroad said the summer used to be a busy time as those with disappointing gaokao results sought places overseas, but this is no longer the case. Teng Zheng, deputy general manager of Shanghai CIIC Education International, said, "Students no longer only regard overseas education as an alternative if they fail the gaokao. Instead, it's becoming some people's first choice." Over the past few years there have been attempts to reform the gaokao system in response to complaints that it is not a scientific way to measure students' academic performance and abilities.
