As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, "outsiders" are going to have some stay over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources.
As Americans consuming such a disproportionate share of the world's resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread, then an additional crust of bread doesn't make that much different. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we're going to have to answer, whether we're trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch.
The prospect of a scarcity of, and competition for, the world's resources require that we reexamine the way in which we relate to the rest of the world. It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them.
The writer warns Americans that ______.
A．their excessive consumption has caused world resource exhaustion
B．they are confronted with the problem of how to obtain more material goods
C．their unfair share of the world's resources should give way to proper division among countries
D．they have to discard their cars for lack of fossil fuel in the world
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth's temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.
This passage is mainly concerned with______.
A．the greenhouse effect
B．the potential effect of air pollution
C．the burning of fossil fuels
D．the probability of a new ice age
The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term.
Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past.
Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25-0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies--to which heavy industry has shifted-have become more energy-intensive, and so could be more seriously squeezed.
One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%.

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic．At present，we realize that although these are the．areas with the worst air pollution，the problem is literally worldWide．On several occasions over the past decade，a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile tmmc．In fact，the very climate of the entire earth may be infected by air poilu-tion．Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels（coal and oil）is creating a“greenhouse effect”——con-serving heat refleeted from the earth and raising the world’S average temperature．If this view is correct and the worid’s temperature is raised only a few degrees，much of the polar ice cap will melt and cities such as New York，Boston，Miami，and New Orleans will be in water． Another view．1ess widely held，is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature——a result that would be equally disas-trous．A drop of just a few degrees could create something close to a new ice age，and would make agriculture difficult or impossible in many of our top fanning areas．Today we do not know for sure that either of these conditions will happen（though one recent government report drafted bv experts in the field concluded that the greenhouse effect is#cry possible）．Perhaps，if we are lucky enough，the two tendencies will offset each other and the world’s temperature will stay about the same as it is now．
As Dointed out at the beginning of the passage，people used to think that air pollution__________ ．
A.caused widespread damage in the countryside
B.affected the entire eastern half of the United States
C.had a damaging effect on health
D.existed merely in urban and industries areas
Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystalclear memory of the dogs, the farm animals, the local birds, and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm had led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil while reading about other people's observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers, and books, which some might honour with the title of scientific research.
But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one the outstanding and essential qualities required is se]f-discipline, a quality I lack. A scientist requires not only self-discipline but hard training, determination and a goal. A scientist, up to a point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.
The first paragraph tells us the author ______. ()
A．was interested in flowers and insects in his childhood
B．lost his hearing when he was a child
C．didn't like his brothers and sisters
D．was born to a naturalist's family
