Benefited or Hurt For the most part, it seems, workers in rich countries have little to fear from globalization, and a lot to gain. But is the same thing true for workers in poor countries The answer is that they are even more likely than their rich country counterparts to benefit, because they have less to lose and more to gain. Orthodox economics takes an optimistic line on integration and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labor have already been used up. If pool countries lower their barriers to trade and investment, the theory goes: rich foreigners will want to send over some of their capital. If this inflow of resources arrives in the form of loans or portfolio investment, it will supplement domestic savings and loosen the financial constraint on additional investment by local companies. If it arrives in the form of new foreign controlled operations, FDI, so much the better: this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investment ought to push incomes up, partly by raising the demand for labor and partly by making labor more productive. This why workers in FDI receiving countries should be in an even better position to profit from integration than workers in FDI sending countries. Also, with or without inflows of foreign capital, the same static and dynamic gains from trade should apply in developing countries as in rich ones. This gain from trade logic often arouses suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets though trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all these transactions, sides exporters and importers, borrowers and lenders, shareholders and workers can gain. Which of the following statements is correct
A rich country gets benefits through trade at the expense of its poor country trading partners
B. A poor country gets benefits through trade at the expense of its rich country trading partners
C. In trade one side or the other must lose because the benefits must come from somewhere.
D. In trade it is possible for every part involved winning at the expense of nobody
The Teacher’s Influence upon the Development of Attitudes Of all the areas of learning, the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance: another is the rise of dictators like Hitler. Both these examples also point out the fact that attitudes stem from experience. In the one case the experience was direct and impressive: in the other it was indirect and accumulative. The Nazis were filled largely with the speeches they heard and the books they read. The classroom teacher in the elementary school is in a strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose words they respect. Another reason, it is true that pupils often study somewhat deeply a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher’s method of handling such a unit would greatly affect his attitude toward Mexicans. The media which the teacher can develop healthy attitudes are innumerable. Social studies (with special reference to races, beliefs and nationalities), science matters of health and safety, the very atmosphere of the classroom, these are a few of the fertile fields for the education of proper emotional reactions. However, when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by scolding them. She can achieve the proper effect by helping them obtain constructive experiences. To illustrate, first grade pupils’ afraid of policemen will properly alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all day trips. Finally, a teacher must constantly evaluate her own attitudes, because her influence can be harmful if she has personal prejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of the facts. A statement NOT made or implied in the passage is that ______.
A. worthwhile attitudes may be developed in practically every subject area
B. a child can develop in the classroom an attitude about the importance of brushing his teeth
C. attitudes cannot easily be changed by rewards and lectures
D. the attitudes of elementary school aged children are influenced primarily by the way they were treated
Electromagnetic Energy 1. White light seems to be a combination of all colors. The energy that comes from a source of light is not limited to the kind of energy you can see. Heat is given off by a flame or an electric light. On a cloudy day it is possible to get a sunburn even though you feel cool. Visible light and the kind of energy that produce warmth and sunburn are examples of electromagnetic energy. 2. The sun is 93 million miles from the earth. Yet we can use energy from the sun because electromagnetic energy travels through space. 3. Many other kinds of energy are also types of electromagnetic energy. Radio, television, and radar signals travel from transmitters to receivers as low-energy electromagnetic waves. Infrared (红外的) radiation is an electromagnetic wave. When it is absorbed by matter, heat is produced. Waves of infrared and visible light have more energy than waves of radio, television, or radar. Ultraviolet rays (紫外线) and X-rays are electromagnetic waves with even greater amounts of energy. Infrared radiation is used in cooking food and heating buildings. Sunlight and electric lights are part of our requirements for normal living. Ultraviolet radiation is useful in killing certain disease organisms. X-rays and gamma rays have so mush energy that they travel right through solid objects. They can be used to detect and treat cancer. X-rays are used in industry to find hidden cracks in metal, and in medicine to reveal broken bones. 4. Usually we use electricity to generate electromagnetic energy. The source of most of our energy is the sun. Heat from the sun causes water to evaporate. When the water fails to the earth as rain, some of it is trapped behind dams and then used to operate electric generators. Other generators are powered by coal, but the energy stored in coal came from the sun, too. 5. Until recently, the source of the tremendous amount of energy given off by the sun was a puzzle. If the sun depended on chemical reactions, it would have used up all its energy long ago. Experiments with electromagnetic radiation led to the theory that mass can be converted into energy. About forty years after the theory was proposed, nuclear energy was harnessed (利用) by man. Chemical energy comes from electron (电子) rearrangement. Nuclear energy comes from a change in the nucleus of an atom. Compared with chemical reactions, nuclear reactions release millions of times more energy per pound of fuel. We now believe that the sun’s energy comes from the nuclear reactions in which hydrogen is changed into helium (氦). 6. Nuclear energy is beginning to compete with coal as an economical source of power to generate electricity. It is also being used to operate engines in large ships. Scientists continue to seek new and better methods of obtaining and using energy. A. Nuclear reactions as the lasting source of the sun’s energy B. The most important source of energy C. Types of electromagnetic energy D. The machines used for energy generation E. Seeking new sources of energy F. The use of ultraviolet radiation in medicine Chemical energy is generated ______.
The Natural Balance Being Altered The balance of nature is a very elaborate and delicate system of check and countercheck. It is continually being altered as climates change, as new organisms evolve, as animals or plants spread to new areas. But the alterations have in the past, for the most part, been slow. whereas with the arrival of civilized man, their speed has been multiplied much: from the evolutionary time-scale where change is measured by periods of ten or a hundred thousand years, they have been transferred to the human time-scale in which centuries and even decades count. Everywhere man is altering the balance of nature. He is facilitating the spread of plants and animals into new regions. Sometimes deliberately, sometimes unconsciously. He is covering huge areas with new kinds of plants, or with houses, factories, slagheaps and other products of his civilization. He gets rid of some species on a large scale, but favors the multiplication of others. In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million years. Many of these changes which he has brought about have had unforeseen consequences. Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade Or that provision of pot cacti for lonely settlers’ wives would have led to Eastern Australia being covered with forests of prickly pears Who would have predicted that the cutting down of forests on the Adriatic coast, or in parts of Central Africa, could have reduced the land to a semi-desert with the very soil washed away from the bare rock Who would have thought that improved communications would have changed history by the spreading of disease- sleeping sickness into East Africa, measles into Ocean, AIDS around the whole world These are spectacular examples, but examples on a smaller scale are everywhere to be found. We made a nature sanctuary for rare birds, providing absolute security for all species; and we may find that some common and hardy kind of birds multiplies beyond measure and drive away the rare kinds in which we are particularly interested. We see, owing to some little change brought about by civilization, the starting spread over the English countryside in hordes. We improve the yielding capacities of our cattle; and find that how they exhaust the pastures which were sufficient for less demanding stock. We gaily set about killing the carnivores that disturb our domestic animals, the hawks that eat our fowls and game-birds; and find that in so doing we are also removing the brake that restrains the multiplication of mice and other little rodents that gnaw away the farmers’ profits. This passage can best be characterized as ______.
A. a reminiscence of times past
B. a thoughtful essay on nature’s laws
C. a lament that so many species vanished
D. an objective discussion of civilization
