单选题{{B}}Text 3{{/B}} Fishing adds only about one percent to the global economy, but on a regional basis it can con- tribute extremely to human survival. Marine fisheries contribute more to the world's supply of protein than beef, poultry or any other animal source. Fishing typically does not need land ownership, and because it remains, generally, open to all, it is often the employer of last resort in the developing world—an occupation when there are no other choices. Worldwide, about 200 million people rely on fishing for their livelihoods. Within Southeast Asia alone, over five million people fish full-time. In northern Chile forty percent of the population lives off the ocean. In Newfoundland most employment came from fishing or servicing that industry—until the collapse of the cod fisheries in the early 1990s that left tens of thousands of people out of work. Though debates over the conservation of natural resources are often cast as a conflict between jobs and the environment, the restoration of fish populations would in fact boost employment. Michael P. Sissenwine and Andrew A. Rosenberg of the U.S. National Marine Fisheries Service have estimated that if depleted species were allowed to rebuild to their long-term potential, their sustainable use would add about $ 8 billion to the U.S. gross domestic product—and provide about 300,000 jobs. If fish populations were restored and properly managed, about twenty million metric tons could be added to the world's annual catch. But restoration of ecological balance, fiscal profitability (收益) and economic security will require'a continual reduction in the capacity of the commercial fishing industry so that wild populations can recover. The necessary reductions in fishing workforce need not come at the expense of jobs. Govern-merits could increase employment and reduce the pressure on fish populations by guiding subsidies a- way from highly mechanised ships. For each $ l ,000,000 of investment, industrial-scale fishing operations require only one to five people, while small-scale fisheries would employ between 60 and 3,000. Industrial fishing itself threatens tens of millions of fishermen working on a small scale by depleting the fish on which they depend for subsistence.

单选题A person may have an idea about himself that will prevent him from doing good work. He may have the idea that he is not capable of it. A child may think he is stupid because he does not understand how to make the most of his mental faculties or he may accept another person's mistaken estimate of his ability. Older people may be handicapped by the mistaken belief that they are incapable of learning anything new because of their age. A person who believes that he is incapable will not make a real effort, because he feels that it would be useless. He won't go at a job without the confidence necessary for success. He is therefore likely to fail, and the failure will strengthen his belief in his incompetence. Alfred Adler, a famous doctor, had an experience which illustrates this. When he was a small boy, he got off to a poor start in arithmetic. His teacher got the idea that he had no ability in arithmetic, and told his parents what she thought in order that they would not expect too much of him. In this way, they too developed the idea, "Isn't it too bad that Alfred can't do arithmetic?" He accepted their mistaken estimate of his ability, felt that it was useless to try, and was very poor at arithmetic, just as they expected. One day, Adler succeeded in solving a problem which none of the other students had been able to solve. This gave him confidence. He rejected the idea that he couldn't do arithmetic and was determined to show them that he could. His newly found confidence stimulated him to go at arithmetic problems with a new spirit. He now worked with interest, determination and purpose, and he soon became extraordinarily good at arithmetic. This experience made him realize that many people have more ability than they think they have, and that lack of success is as often the result of lack of knowledge of how to apply one's ability, lack of confidence and lack of determination as it is the result of lack of ability.

单选题Nearly everyone agrees that money doesn't buy as much as it used to, no matter were you want to spend it. This is certainly true of the paper money that passes so quickly through one' s hands. Inflation eats away 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, 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 solid these are unlikely ever to the auction market. So what happened to some 19,564 ladle 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.
