A Debate on the English Language
A measure declaring English the national language is under intense debate in the United States. The US Senate passed two declarations last week. One calls English the nation's official language and the other says it is the “common and unifying(统一的)”tongue. But Americans found themselves divided on the issue.
Since people worldwide know that most Americans speak only English, many can't understand why the issue is so controversial(有争议的).
“The discussion is related to fears of immigration issues,” says Dick Tucker, a social scientist at Pittsburgh's Carnegie Mellon University. “It's related to a worry about the changing demography(人口统计)of the US. It's a worry about who will continue to have political and economic influence.”
In fact, the notion of protecting the language has been kicked around almost since the nation's founding. John Adams lobbied(游说)in 1780 for the creation of a national academy to correct and improve the English language. But his proposal died, since lawmakers saw it as a royalist(保皇主义者)attempt to define personal behavior.
Since then, the country hasn't had a national language, but the idea of recognizing the special status of English lived on.
The emotions surrounding language resurface(再次浮现)not because people feel comfortable with English. It is more about the discomfort many Americans feel with the new languages, says Walt Wolfram, a professor at North Carolina State University.
“Language is never about language,” he says.
According to the 2000 US Census Bureau report, of 209 million Americans over 18 years old,172 million speak only English at home. About 37 million speak languages other than English. Among them, 6.5 million speak poor English and 3.1 million don't speak English at all.
What are the two declarations concerned with？
A．The status of the English language.
B．The protection of new languages.
C．The rights to speak one's mother tongue.
D．The improvement of the English language.
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 of 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 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 Unites States
