Passage Three

As a medium of exchange, money permits the separation of exchange into the two distinct acts of buying and selling. Hence producers who know they will be paid in money, can concentrate on finding the most suitable outlet for their goods, while buyers who will pay in money, can concentrate on finding the cheapest market for the wings they wish to purchase. (83) Specialization is encouraged, because people whose output is not a complete product but only a part of one can be paid an amount equivalent to their share of the product.

Another advantage of money is that it is a measure of value. In a barter economy it would be necessary to determine how many plates were worth one hundred weight of cotton, or how many pens should be exchanged for a ton of coal. (84) The process of establishing relative values would have to be undertaken for every act of exchange, according to what products were being offered against one another, and according to the two parties ’ desires and preferences.

Thirdly, money acts as store of wealth. It is difficult to imagine saving under a barter system. No one engaged on only one stage in the manufacture of a product could save part of his output, since he would be producing nothing complete. Most products deteriorate fairly rapidly, either physically or in value, as a result of long storage; even if storage were possible, the practice of storing products for years on end would involve 20 obvious disadvantages. If wealth could not be saved, or only with great difficulty, future needs could not be provided.Using money as a medium of exchange means that_____.

Of course we couldn’t see anything because of the fog,but the pilot saidthere was nothing to worry about.The next thing we know, the engines went dead. There was arushing noise—and after that I don’t remember any more.”Mr. Collins is now in hospital, being treated for minor injuries.

13.Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Are you afraid to ask someone for a date? Many people are afraid to assert themselves(坚持己见).Dr.Robert Alberti，author of Stand Up, Speak Out，and Talk Back, thinks it’s because of their lack of confidence.“Our structure of organization tends to make people distrust hemselves.”says Alberti.“There’s always a‘superior’around-a parent，a teacher，a boss-who‘knows better’.These‘superiors’often gain whenthey keep breaking at your self-image.”But Alberti and other scientists are doing something to help people assert themselves.They offer“assertiveness training”courses-AT for short.In the AT course people learn that they have a right to be themselves.They learn to speak out and feel good about doing so.They learn to beaggressive without hurting people.In one way, learning to speak out is to overcome fear.A group taking an AT course will help the shy person to lose his fear.But AT uses an even stronger motive-the need to share.The shy person speaks out in the group because he wants to tell how he feels.Whether or not you speak up for yourself depends on your self-image.If someone you face is more“important”than you，you may feel less of a person.You start to doubt your own good sense.You go by the other person’ s label.But，why should you?AT says you can get to feel good about yourself.And once you do，you can learn to speak out.People are reluctant to talk back because____.

14.The dog has always been considered man’s best friend. Always noted for being particularly faithful in watching over children, he also has his place by the fireside, in the cow pasture, on the sheep range(放牧区), and beside the hunter in forest. He is easy to train, works hard, and often performs astonishing feats. And in the frozen polar regions he was once the principal motive power, before being lately displaced by the plane and helicopter.　　Because he howls or whines in the presence of impending death, the dog was once thought to have supernatural powers and believed to be capable of seeing gods and ghosts invisible to men. Actually, the basis for these beliefs lies in the hound’s sensibility to people’s feelings and his superior hearing ability and sense of smell, which enable him to detect signs hidden from human observation. His record of saving lives is outstanding, for he often gives warning of fire and other dangers not noticed by his master.　　The dog’s major contribution, however, has been to medical research. Both his diet and his structure are comparable to those of the human being, and so he has been the subject of countless demonstrations and experiments. Open heart surgery has been made possible largely because of the dog. But his sacrifice has repaid his own species as well by safeguarding it from rabies(狂犬病), distemper, and other diseases.The dog has always been noted for

Passage Two

In the modern technological world the sea offers many resources to help mankind survive. (82)Resources on land are beginning to grow less. The sea, however, still offers hope to supply many of man’s needs.

The riches of the sea yet to be developed by man’s technology are impressive. Oil and gas explorations have existed for nearly thirty years. Valuable amounts of minerals such as iron, nickel and copper and so on exist on the ocean floor, ready to be mined.

Fish farming promises to be a good way to produce large quantities of food.The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental peoples.

Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy such as hydroelectric power.

Technology is enabling man to explore ever deeper under the sea.The new undersea technology is providing divers with diving suits and undersea chambers that are kept at sea level pressure. The development of strong,new materials has made this possible. The technology to harvest the sea continues to improve. By the year 2000, experts believe that the problems to exploit the food, minerals, and energy sources of the sea will be largely solved.Why does the author mention a steamship?
