7、es raged out of control as the country suffered its worst drought for 50 years. Smoke from the fires mixed with sunlight and hot dry air to form a cloud of smog. This pollution quickly spread and within days it was hanging over neighbouring countries including Malaysia, Singapore and Thailand.When t
8、he smoke combined with pollution from factories and cars, it soon became poisonous (有毒的). Dangerous amounts of CO became trapped under the smog and pollution levels rose. People wheezed (喘息) and coughed as they left the house and their eyes watered immediately.The smog made it impossible to see acro

15、，分数：8.00)Electromagnetic Energy1. 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 fee
16、l 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 e
17、lectromagnetic 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
18、 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 us
19、eful 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 electri
20、city 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
21、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
22、 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 rel
23、ease millions of times more energy per pound of fuel. We now believe that the suns 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
24、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 suns energyB. The most important source of energyC. Types of electromagnetic energyD. The machines used for energy generationE. Seekin

But is the same thing true fo
28、r 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 investmen
29、t 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 countri
30、es 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 inves
31、tment 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
32、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 a
33、nd 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
34、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.（分数：15.00）(1).According to the passage, who may be reason
35、ably afraid of the globalization? A. Workers in rich countries B. Workers in poor countries C. Both of them D. None of them（分数：3.00）A.B.C.D.(2).The phrase “take an optimistic line on“ in the second paragraph probably means to _. A. take the same side with B. hold the optimistic idea about C. stand a

It will loosen the financial constraint C. It will push incomes up D. It will bring technology and skills from abroad（
37、分数：3.00）A.B.C.D.(4).Which of the following statements is correct? A. 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
38、 lose because the benefits must come from somewhere. D. In trade it is possible for every part involved winning at the expense of nobody（分数：3.00）A.B.C.D.(5).Which can be the most appropriate title for this passage? A. Benefited or Hurt B.

It is continually being altered as climates change, as new organisms evolve, as animals or plants spread to new areas. But the al
40、terations 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 wh
41、ich 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 o
42、ther 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 ab
43、out 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
44、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
45、 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
46、 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 improv
47、e 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 removin
48、g the brake that restrains the multiplication of mice and other little rodents that gnaw away the farmers profits.（分数：15.00）(1).The authors concern with the balance of nature, as evidenced by this passage, is best defined as _. A. intense and objective B. conscientious but humorless C. sincere and subjective D. deep but dry（分数：3.
