Much research has been done to test a hypothesis(假说) proposed by linguists called the Critical Period Hypothesis. This hypothesis states that if humans do not learn a foreign language before a certain age, perhaps around puberty(青春期), then due to changes such as maturation of the brain, it becomes impossible to learn the foreign language like a native speaker. No definite answer to this hypothesis has been found and it is still debated by researchers, but there is some evidence that this hypothesis is true for acquiring native-like pronunciation even though there is less evidence that it is true for acquiring the grammar or the vocabulary of a foreign language. Even though nobody knows for certain what exactly happens to our brains as we mature, almost everyone agrees that almost all people who learn a foreign language after puberty will always have an accent. That is, native speakers will be able to identify that the person is not a native speaker of that language. The amount of exposure to English is another factor that determines if the students can acquire native-like English pronunciation. At the present time, most Chinese learners of English do not have enough exposure to English to acquire native-like pronunciation.
Due to biological and physiological differences, individual students have different phonetic ability. Some students are more sensitive to and better at imitating sounds than other students. Although a few students can acquire native-like pronunciation, it is unrealistic for the majority of students to do so. However, admitting the difficulty in acquiring native-like pronunciation does not mean that teachers should not encourage students to improve their pronunciation as much as possible.
Some students take great pains to be accurate in pronunciation. This is often clone at the expense of consistency. And the speech produced in this way is not only unnatural but also uncomfortable to hear. When trying to achieve consistency in pronunciation, students do not have to and should not sacrifice intelligibility(理解). Unintelligible speech is useless and may cause unpleasant feelings for both the speaker and the audience.
We can infer from the first paragraph that______.

听力原文： Exercise is beneficial to your heart. A 22-year study was conducted by doctors in California. They found that people who work at physical jobs experience fewer heart attacks than other people. The active people work all the time at moderated speeds. Their daily routine gives them an adequate amount of exercise and helps them stay in shape. However, machines that can do heavy labor more speedily are replacing this type of work.

Once a rural country, the United States is today a highly urbanized country, and three-quarters of its citizens now live in towns, large cities or their suburbs. This statistic makes city governments critically important in the over-all pattern of American government. To a greater extent than on the federal or state level, the city ministers(Jiffy) directly to the needs of the people, providing everything from police and fire protection to sanitary codes(卫生条例), health regulations, education, public transportation and housing.
Their huge size makes the business of running America's large cities enormously complex. Only seven states of the union, for example, have populations larger than that of New York City. It is often said that, next to the Presidency, the most difficult administrative position in the country is that of Mayor of New York.
The federal, state and city governments by no means cover the whole spectrum(范围) of American governmental units. The U.S. Bureau of the Census has confirmed that there are no less than 78, 218 local governmental units in the United States: counties, municipalities, townships, school districts and special districts.
The county is a subdivision of the state usually—but not always containing two or more townships and several villages. New York City is so large that it is divided into five separate districts, each a county in its own right: The Bronx, Manhattan, Brooklyn, Queens and Richmond. On the other hand, Arlington County, Virginia, just across the Potomac River from Washington D.C., is both an urbanized and suburban area, governed by a unitary county administration.
In most counties, one town or city is designated as the county seat where the government offices are located and where the board of commissioners(委员) or supervisors meets. In small counties, boards are chosen by the county as a whole; in the larger ones, supervisors represent separate districts or townships. The board levies taxes, borrows and grants money, fixes the salaries of county employees, supervises election, builds and maintains highways and bridges, and administers national, state and county welfare programs.
We can infer from the first paragraph that______.
A．By talking to an expert.B．By reading an article.C．By attending an exercise class.D．B
