单选题Less than 40 years ago in the United States, it was common to change a one-dollar bill for a dollar"s worth of silver. That is because the coins were actually made of silver. But those days are gone. There is no silver in today"s coins. When the price of the precious metal rises above its face value as money, the metal will become more valuable in other uses. Silver coins are no longer in circulation because the silver in coins is worth much more than their face value. A silver firm could find that it is cheaper to obtain silver by melting down coins than by buying it on the commodity markets. Coins today are made of an alloy of cheaper metals. Gresham"s Law, named after Sir Thomas Gresham, argues that "good money" is driven out of circulation by "bad money". Good money differs from bad money because it has higher commodity value. Gresham lived in the 16th century in England where it was common for gold and silver coins to be debased. Governments did this by mixing cheaper metals with gold and silver. The governments could thus make a profit in coinage by issuing coins that had less precious metal than the face value indicated. Because different mixings of coins had different amounts of gold and silver, even though they bore the same face value, some coins were worth more than others as commodities. People who dealt with gold and silver could easily see the difference between the "good" and the "bad" money. Gresham observed that coins with a higher content of gold and silver were kept rather than being used in exchange, or were melted down for their precious metal. In the mid-1960s when the U.S. issued new coins to replace silver coins, Gresham"s law went right in action.

单选题Why do people always want to get up and dance when they hear music? The usual explanation is that there is something embedded in every culture — that dancing is a " cultural universal". A researcher in Manchester thinks the impulse may be even more deeply rooted than that. He says it may be a reflex reaction. Neil Todd, a psychologist at the University of Manchester, told that he first got an inkling that biology was the key after watching people dance to deafeningly loud music. "There is a compulsion about it," he says. He reckoned there might be a more direct, biological, explanation for the desire to dance, so he started to look at the inner ear. The human ear has two main functions: hearing and maintaining balance. The standard view is that these tasks are segregated so that organs for balance, for instance, do not have an acoustic function. But Todd says animal studies have shown that the sacculus, which is part of the balance-regulating vestibular system, has retained some sensitivity to sound. The sacculus is especially sensitive to extremely loud noise, above 70 decibels. "There's no question that in a contemporary dance environment, the sacculus will be stimulated," says Todd. The average rave, he says, blares music at a painful 110 to 140 decibels. But no one really knows what an acoustically stimulated sacculus does. Todd speculates that listening to extremely loud music is a form of " vestibular self-stimulation": it gives a heightened sensation of motion. "We don't know exactly why it causes pleasure," he says. "But we know that people go to extraordinary lengths to get it. " He lists bungee jumping, playing on swings or even rocking to and fro in a rocking chair as other examples of pursuits designed to stimulate the sacculus. The same pulsing that makes us feel as though we are moving may make us get up and dance as well, says Todd. Loud music sends signals to the inner ear which may prompt reflex movement. "The typical pulse rate of dance music is around the rate of locomotion," he says. "It's quite possible you're triggering a spinal reflex. "

单选题{{B}}Passage Five{{/B}} I was introduced to the concept of literacy animator in Oladumi Arigbede's (1994) article on high illiteracy rates among women and school dropout rates among girls. According to Arigbede, literacy animators view their role as assisting in the self-liberating development of people in the world who are struggling for a more meaningful life. Animators are a family of deeply concerned and committed people whose gut-level rejection of mass human pauperizafion compels them to intervene on the side of the marginalized. Their motivation is not derived from a love of literacy as merely another technical life skill, and they accept that literacy is never culturally or ideologically neutral. Arigbede writes from her experiences as an animator working with women and men in Nigeria. She believes that literacy animators have to make a clear choice about whose culture and whose ideology will be fostered among those with whom they work. Do literacy educators in the United States consider whether the instruction they pursue conflicts with their students' traditional cultures or community, or fosters illiteracies in learners' first or home languages or dialects and in their orality? Some approaches to literacy instruction represent an ideology of individualism, control, and competition. Consider, for example, the difference in values conveyed and represented when students engage in choral reading versus the practice of having one student read out loud to the group. To identify as a literacy animator is to choose the ideology of "sharing, solidarity, love, equity, co-operation with and respect of both nature and other human beings". Literacy pedagogy that matches the animator ideology works on maintaining the languages and cultures of millions of minority children who at present are being forced to accept the language and culture of the dominant group. It might lead to assessment that examines the performance outcomes of a community of literacy learners and the social significance of their uses of literacy, as opposed to measuring what an individual can do as a reader and writer on a standardized test. Shor(1993) describes literacy animators as problem-posing, community-based, dialogic educators. Do our teacher-education textbooks on reading and language arts promote the idea that teachers should explore problems from a community-based dialogic perspective?
