单选题How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language; a grown-up person with fully developed mental powers, in most cases, may end up with a faulty and inexact command. What accounts for this difference? Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behavior of the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, right use of words and right structure. He drinks in all the words and expressions which come to him in a fresh, ever-bubbling spring. There is no resistance: there is perfect assimilation. Then the child has, as it were, private lessons all the year round, while an adult language student has each week a limited number of hours which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again, when his attempts at speech are successful, his desires are understood and fulfilled. Finally, though a child's "teachers" may not have been trained in language teaching, their relations with him are always close and personal. They take great pains to make their lessons easy.

单选题For more than two decades, U. S. courts have been limiting affirmative-action programs in universities and other areas. The legal rationale is that racial preferences are unconstitutional, even those intended to compensate for racism or intolerance. For many colleges, this means students can be admitted only on merit, not on their race or ethnicity. It has been a divisive issue across the U. S., as educators blame the prolonged reaction to affirmative-action for declines in minority admissions. Meanwhile, activists continue to battle race preferences in courts from Michigan to North Carolina. Now, chief executives of about two dozen companies have decided to plunge headfirst into this politically unsettled debate. They, together with 36 universities and 7 nonprofitable organizations, formed a forum that set forth an action plan essentially designed to help colleges circumvent court-imposed restrictions on affirmative action. The CEOs' motive. "Our audience is growing more diverse, so the communities we serve benefit if our employees are racially and ethnically diverse as well", says one CEO of a company that owns nine television stations. Among the steps the forum is pushing, finding creative yet legal ways to boost minority enrollment through new admissions policies; promoting admissions decisions that look at more than test scores; and encouraging universities to step up their minority outreach and financial aid. And to counter accusations by critics to challenge these tactics in court, the group says it will give legal assistance to colleges sued for trying them. "Diversity diminished by the court must be made up for in other legitimate, legal ways, " says, a forum member. One of the more controversial methods advocated is the so-called 10% rule. The idea is for public universities—which educate three-quarters of all U. S. undergraduates—to admit students who are in the top 10% of their high school graduating class. Doing so allows colleges to take minorities who excel in average urban schools, even if they wouldn't have made the cut under the current statewide ranking many universities use.

单选题Given the fact that each person is only one of approximately 90 million voters in this country, does it make sense to believe that one person"s participation, one vote, will have any impact on a major election? Simply to raise the question "What if everyone felt the same way?" does not remove the lingering impression that a single person is made to feel insignificant by the enormous number of people who do go to the polls, especially in a national election. Supporters of the ruling elite theory insist that even though voters are given a choice among candidates, their choice is restricted to a narrow range of similar-minded individuals approved by the ruling elite. Elections do not express what most people want or need, nor do they provide guidance for politicians (even if they want it) on what policies to enact. In this view, elections are primarily just rituals that perform a symbolic function for society. Still, since most people continue to show faces at the polls at one time or another, what arguments can be made in favor of voting? One argument is that voting does have significance, if not in individual impact, then in group pressure. Because citizens collectively have the power to give or withhold votes, they directly control the term in office of elected officials. Even if the choice is between Tweedledee and Tweedledum , Tweedledee knows that one must be accountable and this is fixed by law, and that minimally he or she must strive to avoid displeasing the constituents to lose the job. But perhaps political effectiveness and impact in voting are not the only consideration anyway. People do not vote only to influence policy. Millions go to the effort to register and vote for a variety of other reasons as well. Some people may participate just to avoid feeling guilty about not voting. They may have been taught that is their patriotic duty to vote and that they have no right to complain about the outcome if they stay at home. Still others may vote to derive satisfaction from feeling that they are somehow participants, not just spectators, in an exciting electoral contest. Even if their one vote may not be crucial to the outcome, it nevertheless affirms their role in and support for the political process. Indeed, perhaps it is this final need that fuels the desire for full democratic participation among people in many nations of the world.
