Some of their talk took the form of tales and vignettes told for their own sake.3. Sometimes humorous, sometimes sad; all were as brig
2、ht as the figures in the fine needlepoint. 4. “These tales included grotesque, comic, and poetic descriptions, character sketches, narratives, gusts of feeling, delicate ironies, and astute observations。 ” 翻译：_2. Above the tree line there is a zone that is generally called alpine tundra. Immediately
3、 adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. Some plants can even
4、 survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. At this great height, rocks, warmed by the sun, melt small snowdrifts. This explains how, for example, alpine cushion plants have been found growing at an
5、 altitude of 6,180 meters. 翻译：3. Although origin in ritual has long been the most popular, it is by no means the only theory about how the theater came into being. Storytelling has been proposed as one alternative. Under this theory, relating and listening to stories are seen as fundamental human pl
6、easures. Thus, the recalling of an event (a hunt, battle, or other feat) is elaborated through the narrators pantomime and impersonation and eventually through each role being assumed by a different person.To enhance their listeners enjoyment, storytellers continually make their stories more engagin
7、g and memorable. 翻译：_4. Much of the water in a sample of water-saturated sediment or the rock will drain from it if the sample is put in a suitable dry place. But some will remain, clinging to all solid surfaces. It is held there by the force of surface tension without which water would drain instan
8、tly from any wet surface, leaving it totally dry. The total volume of water in the saturated sample must therefore be thought of as consisting of water that can, and water that cannot, drain away. What, then, determines what proportion of the water stays and what proportion drains away? 翻译：_Lillian
9、苑5. Modern architectural forms generally have three separate components comparable to elements of the human body; a supporting skeleton or frame, an outer skin enclosing the interior spaces, equipment, similar to the bodys vital organs and systems. The equipment includes plumbing, electrical wiring,
10、 hot water, and air-conditioning. Of course in early architecturesuch as igloos and adobe structuresthere was no such equipment, and the skeleton and skin were often one.However, some modern architectural designs, such as those using folded plates of concreter or air-inflated structures, are again u
11、nifying skeleton and skin. 翻译：_6. Ecologists are especially interested to know what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities. The destruction caused by the volcanic explosion of Mount
12、 St. Helens, in the northwestern United States, for example, pales in comparison to the destruction caused by humans. We need to know what aspects of a community are most important to the communitys resistance to destruction, as well as its recovery. In fact, damage to the environment by humans is o
13、ften much more severe than damage by natural events and processes. 翻译：_7. The reaction of farmers to the inevitable depletion of the Ogallala varies. Many have been attempting to conserve water by irrigating less frequently or by switching to crops that require less water. Other, however, have adopt
14、ed the philosophy that it is best to use the water while it is still economically profitable to do so and to concentrate on high-value crops such as cotton. The incentive of the farmers who wish to conserve water is reduced by their knowledge that many of their neighbors are profiting by using great
15、 amounts of water, and in the process are drawing down the entire regions water supplies. In the face of the upcoming water supply crisis, a number of grandiose schemes have been developed to transport vast quantities of water by canal or pipeline from the Mississippi, the Missouri, or the Arkansas
16、rivers. Unfortunately, the cost of water obtained through any of these schemes would increase pumping costs at least tenfold, making the cost of irrigated agricultural products from the region uncompetitive on the national and international markets.But even if uncooperative farmers were to join in t
17、he conservation efforts, this would only delay the depletion of the aquifer. 翻译：_8. Where the forest inhibits the growth of grass and other meadow plants, the black-tailed deer browses on huckleberry, salal, dogwood, and almost any other shrub or herb. But this is fair-weather feeding. What keeps th
18、e black-tailed deer a lived in the harsher seasons of plant decoy and dormancy? One compensation for not hibernating is the built-in urge to migrate. Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. Even with snow on the ground, the high bushy understo
19、ry is exposed; also Lillian 苑snow and wind bring down leafy branches of cedar, hemlock, red alder, and other arboreal fodder. The numbers of deer have fluctuated markedly since the entry of Europeans into Puget Sound country. The early explorers and settlers told of abundant deer in the early 1800s
20、and yet almost in the same breath bemoaned the lack of this succulent game animal. There food is available and accessible throughout the winter.翻译：_9. The subjects of the paintings are mostly animals. The paintings rest on bare walls, with no backdrops or environmental trappings. Perhaps, like many
21、contemporary peoples, Upper Paleolithic men and women believed that the drawing of a human image could cause death of injury, and if that were indeed their belief, it might explain why human figures are rarely depicted in cave art. Another explanation for the focus on animals might be that these peo
22、ple sought to improve their luck at hunting. This theory is suggested by evidence of chips in the painted figures, perhaps made by spears thrown at the drawings. But if improving their hunting luck was the chief motivation for the paintings, it is difficult to explain why only a few show signs of ha
23、ving been speared. Perhaps the paintings were inspired by the need to increase the supply of animals. Cave art seems to have reached a peak toward the end of the Upper Paleolithic period, when the herds of game were decreasing.Therefore, if the paintings were connected with hunting, some other expla
24、nation is needed. 翻译：_10. Continued sedimentationthe process of deposits settling on the sea bottomburies the organic matter and subjects it to higher temperatures and pressures, which convert the organic matter to oil and gas. As muddy sediments are pressed together, the gas and small droplets of o
25、il may be squeezed out of the mud and may move into sandy layers nearby. Over long periods of time (millions of years), accumulations of gas and oil can collect in the sandy layers. Both oil and gas are less dense than water, so they generally tend to rise upward through water-saturated rock and sed
26、iment.Unless something acts to halt this migration, these natural resources will eventually reach the surface. 翻译：_11. Scientists have known for some time that certain plants, called hyperaccumulators, can concentrate minerals at levels a hundredfold or greater than normal. A survey of known hyperac
27、cumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice.Hyperaccumulators run the Lillian 苑entire range of the plant world. They may be herbs, shrubs, or trees.Many members of the mustard family, spurge family, leg
28、ume family, and grass family are top hyperaccumulators. Many are found in tropical and subtropical areas of the metals may afford some protection against plant-eating insects and microbial pathogens.Certain minerals are more likely to be accumulated in large quantities than others.翻译：_12. Speculatio
29、n on the origin of these Pacific islands began as soon as outsiders encountered them; in the absence of solid linguistic, archaeological, and biological data, many fanciful and mutually exclusive theories were devised. Pacific islanders were variously thought to have come from North America, South A
30、merica, Egypt, Israel, and India, as well as Southeast Asia. Many older theories implicitly deprecated the navigational abilities and overall cultural creativity of the Pacific islanders. For example, British anthropologists G.Elliot Smith and W.J.Perry assumed that only Egyptians would have been sk
31、illed enough to navigate and colonize the Pacific. They inferred that the Egyptians even crossed the Pacific to found the great civilizations of the New World (North and South America). In 1947 Norwegian adventurer Thor Heyerdahl drifted on the balsa-log raft westward with the winds and currents acr
32、oss the Pacific from South America to prove his theory that Pacific islanders were Native Americans (also called American Indians).Later theories concentrated on journeys in the other direction.翻译：_13. One interpretation regarding the absence of fossils during this important 100-million-year period
33、is that early animals were soft bodied and simply did not fossilize. Fossilization of soft-bodied animals is less likely than fossilization of hard-bodied animals, but it does occur. Conditions that promote fossilization of soft-bodied animals include very rapid covering by sediments that create an
34、environment that discourages decomposition. In fact, fossil beds containing soft-bodied animals have been known for many years. It is relatively rare because the fossilization of soft-bodied animals requires a special environment.翻译：_14. Watts steam engine soon showed what it could do. It liberated
35、industry from dependence on running water. The engine eliminated water in the mines by driving efficient pumps, which made possible deeper and deeper mining. The ready availability of coal inspired William Murdoch during the 1790s to develop the first new form of nighttime illumination to be discove
36、red in a millennium and a half. Coal gas rivaled smoky oil lamps and flickering candles, and early in the new century, welltodo Londoners grew accustomed to gaslit houses and even streets. Iron manufacturers which had starved for fuel while depending on charcoal also benefited from ever-increasing s
37、upplies of coal; blast furnaces with steam-powered bellows Lillian 苑turned out more iron and steel for the new machinery. Steam became the motive force of the Industrial Revolution as coal and iron ore were the raw materialsThe factories did not have to go to the streams when power could come to fac
38、tories.翻译：_15. Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging: certain fossils always appear in more ancient sediments, while others begin to be seen as the strata become more recent. By following the fossils, Smith was able to put all t
39、he strata of Englands earth into relative temporal sequence. About the same time, Georges Cuvier made the same discovery while studying the rocks around Paris. Soon it was realized that this principle of faunal (animal) succession was valid not only in England or France but virtually everywhere. It
40、was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna. Limestone may be found in the Cambrian or-300 million years later-in the Jurassic strata but a trilobitethe ubiquitous marine arthropod that had its birth in the Cambrianwi
41、ll never be found in Jurassic strata, nor a dinosaur in the Cambrian.The findings of these geologists inspired others to examine the rock and fossil records in different parts of the world.翻译：_16. What do you remember about your life before you were three? Few people can remember anything that happe
42、ned to them in their early years. Adults memories of the next few years also tend to be scanty. Most people remember only a few events-usually ones that were meaningful and distinctive, such as being hospitalized or a siblings birth.Other important occasions are school graduations and weddings.翻译：_1
43、7. Modern attitudes to Roman civilization range from the infinitely impressed to the thorough disgusted. As always, there are the power worshippers, especially among historians, who are predisposed to admire whatever is strong, who feel more attracted to the might of Rome than to the subtlety of Gre
44、ece. At the same time, there is a solid body of opinion that dislikes Rome. For many, Rome is at best the imitator and the continuator of Greece on a larger scale. Greek civilization had quality; Rome, mere quantity. Greece was the inventor; Rome, the research and development division. Such indeed w
45、as the opinion of some of the more intellectual Romans.” had the Greeks held novelty in such disdain as we,” asked Horace in his epistle, “what work of ancient date would now exist?”They esteem symbols of Roman power, such as the massive Colosseum.翻译:_18. The diffusion of agriculture and later of iron was accompanied by a great movement of people Lillian 苑who may have carried these innovations. These people probably originated in eastern Nigeria. Their migration may have been set in motion by an increase in po
