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 ) 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？

Nine bus passangers were killed in the Collision, near the village of Ovrazhroye in the Kaliningrad region. Two more later died from their injuries and 17 were being treated in hospital It was unclear whether the driver was among the victims.
"It is difficult to give the precise number of victims be- cause there are a lot of body parts at the scene, and their identification will be difficult, "Klimov said.

This question is interest for a number of reasons. Apart from curiosity about the level of animals' understanding, research on self-recognition in animals has several benefits. It provides some insight into the evolutionary significance of this skill of self-recognition and into the level and kinds of cognitive competence that the skill requires. Such research also indicates the kinds of learning experiences that determine the development of self-recognition. In addition, work with animals fosters the use of techniques that are not dependent on verbal responses and that may therefore be suitable for use with preverbal children.
The evidence indicates that dogs and almost all other nonhumans do not recognize themselves. In a series of clever experiments, however, Gallup has shown that the chimpanzee does have this capacity. Gallup exposed chimpanzees in a small cage to a full-length mirror for ten consecutive days. It was observed that over this period of time the number of self-directed responses increased. These behaviors included grooming parts of the body while watching the results, guiding fingers in the mirror, and picking at teeth with the aid of the mirror. Describing one chimp, Gallup said, "Marge used the mirror to play with and inspect the bottom of her feet; she also looked at herself upside down in the mirror while suspended by her feet from the top of the cage; she was also observed to stuff celery leaves up her nose using the mirror for purposes of visually guiding the stems into each nostril."
Then the researchers devised a further test of self-recognition. The chimps were anesthetized and marks were placed over their eyebrows and behind their ears, areas the chimps could not directly observe. The mirror was temporarily removed from the cage, and baseline data regarding their attempts to touch these areas were recorded. The data clearly suggest that chimps do recognize themselves, or are self-aware, for their attempts to touch the marks increased when they viewed themselves. Citing further evidence for this argument, Gallup noted that chimpanzees with no prior mirror experience did not direct behavior. to the marks when they were first exposed to the mirror; that is, the other chimpanzees appeared to have remembered what they looked like and do have responded to the marks because they noticed changes in their appearance.
The idea of this passage is to discuss______.
