tpo47阅读-3Coral Reefs原文 (1)译文 (2)题目 (3)答案 (7)背景知识 (7)原文Coral Reefs①An important environment that is more or less totally restricted to the intertropical zone is the coral reef. Coral reefs are found where the ocean water temperature is not less than 21 °C, where there is a firm substratum, and where the seawater is not rendered too dark by excessive amounts of river-borne sediment. They will not grow in very deep water, so a platform within 30 to 40 meters of the surface is a necessary prerequisite for their development. Their physical structure is dominated by the skeletons of corals, which are carnivorous animals living off zooplankton. However, in addition to corals there are enormous quantities of algae, some calcareous, which help to build the reefs. The size of reefs is variable. Some atolls are very large—Kwajelein in the Marshall Islands of the South Pacific is 120 kilometers long and as much as 24 kilometers across-but most are very much smaller, and rise only a few meters above the water. The 2,000 kilometer complex of reefs known as the Great Barrier Reef, which forms a gigantic natural breakwater off the northeast coast of Australia, is by far the greatest coral structure on Earth.②Coral reefs have fascinated scientists for almost 200 years, and some of the most pertinent observations of them were made in the 1830s by Charles Darwin on the voyage of the Beagle. He recognized that there were three major kinds: fringing reefs, barrier reefs, and atolls; and he saw that they were related to each other in a logical and gradational sequence. A fringing reef is one that lies close to the shore of some continent or island. Its surface forms an uneven and rather rough platform around the coast, about the level of low water, and its outer edge slopes downwards into the sea. Between the fringing reef and the land there is sometimes a small channel or lagoon. When the lagoon is wide and deep and the reef lies at some distance from the shore and rises from deep water it is called a barrier reef. An atoll is a reef in the form of a ring or horseshoe with a lagoon in the center.③Darwin s theory was that the succession from one coral reef type to another could be achieved by the upward growth of coral from a sinking platform, and that there would be a progression from a fringing reef, through the barrier reef stage until, with the disappearance through subsidence (sinking) of the central island, only a reef-enclosed lagoon or atoll would survive. A long time after Darwin put forward this theory, some deep boreholes were drilled in the Pacific atolls in the 1950s. Thedrill holes passed through more than a thousand meters of coral before reaching the rock substratum of the ocean floor, and indicated that the coral had been growing upward for tens of millions of years as Earth's crust subsided at a rate of between 15 and 51 meters per million years. Darwin s theory was therefore proved basically correct. There are some submarine islands called guyots and seamounts, in which subsidence associated with sea-floor spreading has been too speedy for coral growth to keep up.④Like mangrove swamps, coral reefs are extremely important habitats. Their diversity of coral genera is greatest in the warm waters of the Indian Ocean and the western Pacific. Indeed, they have been called the marine version of the tropical rain forest, rivaling their terrestrial counterparts in both richness of species and biological productivity. They also have significance because they provide coastal protection, opportunities for recreation, and are potential sources of substances like medicinal drugs. At present they are coming under a variety of threats, of which two of the most important are dredging and the effects of increased siltation brought about by accelerated erosion from neighboring land areas.译文珊瑚礁①或多或少完全局限于热带的重要环境是珊瑚礁。

TPO56 阅读-3 Conditions on Early Earth and the Beginnings of Life原文 (1)译文 (2)题目 (3)答案 (8)背景知识 (8)原文Conditions on Early Earth and the Beginnings of Life①A little more than 3.8 billion years ago is a good estimate of when life began on Earth. How it began remains speculative. There is no standard theory; there is instead a confusion of conflicting theories that attack the problem from different angles. This is a change from 1953 when a classic experiment on the origin of life was published. Then, Stanley Miller and Harold Urey had just completed their famous laboratory simulation of the conditions of an early Earth at the University of Chicago. When Miller and Urey let electric sparks course like lightning through an “atmosphere”of methane, ammonia, and hydrogen, which circulated above an “ocean”of boiling water, they found that a reddish substance, rich in amino acids, accumulated in their glass apparatus. Amino acids, when strung together in long folded chains, form proteins, and proteins are the building blocks of the living cell. From the spontaneous synthesis of amino acids to the spontaneous origin of life on the primitive Earth did not seem such a long way to go.②That early optimism has proven profoundly mistaken, for at least two reasons. The first is simply that it is, in fact, a long way from amino acids to life. The hardest part about creating life is not making the amino acids that go into proteins; or the sugars, phosphates, and bases that go into DNA, which carries the cell’s genetic blueprint; or the lipids that form its protective membrane. The hardest part about creating life is not making the “bricks”: it is assembling them into a finished structure. That is what all the theories that have emerged since the Miller-Urey experiment are primarily about, and the conflict among them shows no signs of being resolved soon.③Furthermore, in recent years even the fundamental premise of that landmark experiment has been called into question. Today most researchers who study early Earth do not believe that its atmosphere was primarily methane and ammonia, which would have been a strongly reducing atmosphere, where reducing meanshydrogen-rich. Methane and ammonia are both comparatively fragile molecules that might easily have been broken apart by the ultraviolet sunlight that bathed the young Earth, which had not yet evolved an ozone shield. More important, the idea that Earth was hot to begin with as a result of its violent birth, when large asteroids collided to form it, implies that its early atmosphere was rich in carbon dioxide rather than methane. That is the form in which carbon would be released by exploding asteroids.④The bottom line is that the early atmosphere is not likely to have been a giant Miller-Urey experiment; it would have been mostly nitrogen and carbon dioxide. In such an atmosphere it is indeed hard to make the molecular bricks of life, let alone a living organism. It is hard even to make the chemical compounds necessary for life. The most important compounds are formaldehyde and hydrogen cyanide, which, brought together in the presence of water, react to produce amino acids, from which the bricks are made. Formaldehyde and hydrogen cyanide, then, seem to be essential stages on the chemical road to life, and hydrogen cyanide especially cannot be made in great quantities in a carbon-dioxide atmosphere. Both compounds, however, are abundant in comets like Halley, Hyakutake, and Hale-Bopp. Presumably they are in other comets as well.⑤Here, then, is an elegant solution to the dilemma. The dilemma is that the old view of how life began conflicts with the new view of how Earth began and how it acquired an ocean. The solution, perhaps, is to deliver the organic precursors of life with the same vehicles that almost certainly helped create the ocean: icy comets. Researchers have calculated that over the course of Earth’s history, comets have delivered an amount of organic matter to the planet that is nearly a million times its present biomass—the total mass of all living things. Most of the organic matter would have arrived during the heavy bombardment that ended 3.8 billion years ago.译文早期地球的条件以及生命的开始①38 亿多年前是地球上生命开始的一个很好的估计。

RUNNING WATER ON MARS
Photographic evidence suggests that liquid water once existed in great quantity on the surface of Mars. Two types of flow features are seen: runoff channels and outflow channels. Runoff channels are found in the southern highlands. These flow features are extensive systems―sometimes hundreds of
interconnecting, twisting channels that seem to
into larger, wider channels. They bear a strong resemblance to river systems on Earth, and geologists think that they are dried-up beds of long-gone rivers that once carried rainfall on Mars from the mountains down into the valleys. Runoff channels on Mars speak of a time 4 billion years ago (the age of the Martian highlands), when the atmosphere was thicker, the surface warmer, and liquid water widespread.
Outflow channels are probably relics of catastrophic flooding on Mars long ago. ■They appear only in equatorial regions and generally do not form extensive interconnected networks. ■Instead, they are probably the paths taken by huge volumes of water draining from the southern highlands into the northern plains. ■Th e onrushing water arising from these flash floods likely also formed the odd
teardrop-shaped “islands”
sand of our beaches at low tide) that have been found on the plains close to the ends of the outflow channels. ■Judging from the width and depth of the channels, the flow rates must have been truly enormous―perhaps as much as a hundred times greater than the 105 tons per second carried by the great Amazon river. Flooding shaped the outflow channels approximately 3 billion years ago, about the same times as the northern volcanic plains formed. Some scientists speculate that Mars may have enjoyed an extended early Period during which rivers, lakes, and perhaps even oceans adorned its surface.
A 2003 Mars Global Surveyor image shows what mission specialists think may be a delta―a fan-shaped network of channels and sediments where a river once flowed into a larger body of water, in this case a lake filling a crater in the southern highlands. Other researchers go even further, suggesting that the data provide evidence for large open expenses of water on the early Martian surface. A computer-generated view of the Martian north polar region shows the extent of what may have been an ancient ocean covering much of the northern lowlands. The Hellas Basin, which measures some 3,000 kilometers across and has a floor that lies nearly 9 kilometers below the basin’s rim, is another candidate for an ancient Martian sea.
These ideas remain controversial. Proponents point to features such as the terraced “beaches” shown in one image, which could conceivably have been left behind as a lake or ocean evaporated and the shoreline receded. But detractors maintain that the terraces could also have been created by
geological activity, perhaps related to the geologic forces that depressed the Northern Hemisphere far below the level of the south, in which case they have nothing whatever to do with Martian water. Furthermore, Mars Global Surveyor data released in 2003 seem to indicate that the Martian surface contains too few carbonate rock layers―layers containing compounds of carbon and oxygen―that should have been formed in abundance in an ancient ocean. Their absence supports the picture of a cold, dry Mars that never experienced the extended mild period required to form lakes and oceans. However, more recent data imply that at least some parts of the planet did in fact experience long periods in the past during which liquid water existed on the surface. Aside from some small-scale gullies (channels) found since 2000, which are inconclusive, astronomers have no direct evidence for liquid water anywhere on the surface of Mars today, and the amount of in the Martian
the extent of the outflow channels suggests that a huge total volume of water existed on Mars in the past. Where did all the water go? The answer may be that virtually all the water on Mars is now locked in the permafrost layer under the surface, with more contained in the planet’s polar caps.。
