D．the demands for various merchandises

.

B．Invention is a new idea to modern people.

to be of approximately equivalent value without any flow of money taking place. It is a primitive way of exchanging. In primitive society, people exchanged goods according to their needs. But with the development of the civilization, the simple way of exchanging goods could no longer meet the demands of people; therefore, a new but more convenient means-money appeared. But the trade of barter did not totally disappear. In intemational trade, a certain amount of foreign exchange is dispensable. For those countries, which do not have enough foreign exchange, they can solve the problem by choosing barter trade.

Branding Your Supply Chain

0 It's no secret to anyone working in the field today that is the supply

00 chain management profession is besieged with immense and

41 rapid change. Managing the modern-day supply chain that requires a

42 conceptually sound, responsive, and agile of approach to problem

43 solving it and execution. It calls for taking a proactive role in

44 managing increasingly global supply chain scenarios in a way

45 that assures in long-term performance. And it demands approaches

46 that may not have been considered as in the past. In short, managing

47 the supply chain today which demands innovation-a willingness to adopt

48 to new mindsets and pursue new approaches. Innovation is a widely

49 recognized and time-honored way of enhancing for business value at

50 the macro or at enterprise level. Less recognized is the potential

51 for innovation to enhance performance being at the micro level of the supply

52 chain function. What's more, innovation can be a powerful driver of supply chain enhancement.

ulation will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volumes of liquid .wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever-increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.

There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents, tn permit the reuse of the water or minimize pollution upon final disposal.

A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable by products. Other industries are exploring potential economic uses for their waste products.

The purpose of this passage is ______.

A．to acquaint the reader with water pollution problems

B．to alert the reader to the dwindling water supply

C．to explain industrial uses of water

D．to demonstrate various measures to solve the pollution problem

听力原文： (35)Research indicates that parents who reward self-control and independence tend to have children with high achievement motivation. (33) Such parents set high standards for their children but allow them to work at their own level and to make their own mistakes. That is to say, they are not very critical. By contrast, parents of low need achievers typically set impossibly high goals for their children and make extreme demands, In addition, parents of high need achievers encourage good performance but do not blame their children angrily when they fail. (34)If a child comes home from school with As and one B on a report card, the parents focus on the As, while not paying much attention to the B; parents of a potential low need achiever tend to ask, "Why the B？" Parents of high need achievers respond to middle grades with warmth and suggestions for reasonable goals and ways to reach them. They can help their children to find a way out. Parents of low need achievers would scold and punish the child. When a child is having trouble with a maths problem, the parents of high need achievers will suggest the general procedure and let the child work out the particular solution; a low need achiever's parent will solve the problem and then hand the child the answer.

Closely related to motivation are emotions, which can activate and direct behavior. in much the same way as physiological, social and psychological motivations do.

A．They usually leave their children alone.

B．They set high standards for their children.

C．They allow for failure on the part of their children.

D．They control their children to a minimum degree.

ate to solve a problem than if only one individual works on it. The assumption is by no means invariably role.

Although groups often may increase the motivation of their members to deal with problems, there is a counterbalancing need to contend with conflicts arising among members of a group-and to give it coherent directions. Problem solving is facilitated by the presence of an effective leader who not only provides direction but permits the orderly, constructive expression of a variety of opinions; much of the leader's effort may be devoted to resolving differences. Success in problem solving also depends on the distribution of ability within a group. Solutions simply may reflect the presence of an outstanding individual who might perform. even better by himself.

Although groups may reach a greater number of correct solutions, or may require less time to discover an answer, their net man-hour efficiency is typically lower than that achieved by skilled individuals working alone.

A process called brainstorming has been offered as a method of facilitating the production of new solutions to problems. In brainstorming, a problem is presented to a group of people who then proceed to offer whatever they can think of, regardless of quality and with as few inhibitions as possible. Theoretically these unrestricted suggestions increase the probability that at least some superior solutions will emerge. Nevertheless, studies show that when individuals work alone under similar conditions, performance tends to proceed more efficiently than it does in groups.

Under special circumstances, however, a group may solve problems more effectively than does a reason ably competent individual. Group members may contribute different (and essential) resources to a solution that no individual can readily achieve alone; such pooling of information and skills can make group achievements superior in dealing with selected problems. Sometimes social demands may require group agreement on a single alternative, as in formulating national economic or military policies under democratic governments. When only one among several alternative solutions is correct, even if a group requires more time, it has a higher probability of identifying the right one than does an individual alone.

In this passage, the author argues that thinking in groups ______.

A．is the best way to solve any problem

B．is by no means useful in problem-solving

C．may result in effective problem-solving under certain circumstances

D．will inevitably produce greater efficiency in problem solving than individual thinking
