Question

　　Nearly everyone agrees that money doesn't buy as much as it used to, no matter where you want to spend it. This is certainly true of the paper money that passes so quickly through one's hands. Inflation (通货膨胀) eats away at its buying power just as the steady appetite of waves chews at sand cliffs. But what about coins that seem to do very little except make purses and pockets untidy? Unlike notes, metal money becomes more valuable the longer it is held, especially if it is put away where it won't get scratched or worn. Why is this? One reason is that coins, being more durable (耐用的), fall more readily into a category for collections. Naturally, the rarer gold pieces must become more valuable as the price of this metal goes up.

    But, curiously, one of the rarest coins in the world is not made of gold, but of the relatively cheaper silver. In 1840, the United States mint struck 19, 570 silver dollars. That is what its records show. Today only six of this original number remain and these are unlikely ever to the auction market. So what happened to some 19, 564 large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American territory then known as Louisiana. But they never reached France. Somewhere in the Gulf of Mexico, the ship transporting them was sunk, either by a storm or by pirates. The probable answer to the mystery is that they were melted down—since the silver value was greater than the actual value of the coin. What really happened to the rest will probably always remain a mystery. What .is known is that whoever can come up with one will find himself instantly rich.

Answer 1

答案：B;D;D;C
解析：

1．B。推断题。本题要求推断，实际上从文章第一句便可查找到所需要的细节。该句讲，钱不像以前那样值钱了。选项B正确，其他三项偏离了原意。     2．D。细节题。文章第一段第五句讲，Unlike notes，metal money becomes more valuable the longer it is held．(与纸币不一样，硬币持币时间越长，价值越大。)据此，选项D符合题意。其他三项均与此细节不一致。     3．D。细节题。第一段最后一句讲，硬币更耐用，很容易成为收藏品，钱币本身的金属会越来越值钱。这与选项B和C一致。根据题意，选项D正确。     4．C。细节题。文章倒数第二句讲，另外的19，564枚银币将永远是个谜。据此选项C正确。其他三项均为无证据的猜测。
