小马托福 010-62699622Savanna FormationP2: Savannas typically experience a rather prolonged dry sea

son. One theory behind savanna formation is that wet forest species are unable to withstand the dry season, and thus savanna, rather than rain forest, is favored on the site. Savannas experience an annual rainfall of between 1000 and 2000 millimeters, most of it falling in a five-to-eight month wet season. Though plenty of rain may fall on a savanna during the year, for at least part of the year little does, creating the drought stress ultimately favoring grasses. Such conditions prevail throughout much of northern South America and Cuba, but many Central American savannas as well as coastal areas of Brazil and the island of Trinidad do not fit this pattern. In these areas, rainfall per month exceeds that in the above definition, so other factors must contribute to savanna formation.

Q3. According to paragraph 3, rain forests and savannas differ in that

A. the soils in rain forests contain fewer minerals than savanna soils doB. savannas affect soil conditions more than rain forests doC. unlike rain forests, savannas prefer sandy, well-drained soils to soils that are very wetD. unlike rain forests, savannas may develop under both very dry and very wet soil conditions

小马托福 010-62699622Q3

P3: In many characteristics, savanna soils are similar to those of some rain forests, though more extreme. For example, savanna soils, like many rain forest soils, are typically oxisols (dominated by certain oxide minerals) and ultisols (soils containing no calcium carbonate),with a high acidity notably low concentrations of such minerals as phosphorus, calcium, magnesium, and potassium, while aluminum levels are high. Some savannas occur on wet, waterlogged soils; other dry, sandy, well-drained soils. This many seem contradictory,but it only means that extreme soil conditions, either too wet or too dry for forests, are satisfactory for savannas. More moderate conditions support moist forests.

Q6. According to paragraph 4, which of the following is true of waterlogged soils?

A. Their upper layers are usually sandy and porous.B. They cannot support savannas.C. They contain little oxygen.D. They are prone to the leaching of nutrients and minerals.

P4: Waterlogged soils occur in areas that are flat or have poor drainage. These soils usually contain large amounts of clay and easily become water-saturated. Air cannot penetrate between the soil particles, making the soil oxygen-poor. By contrast, dry soils are sandy and porous, their coarse textures permitting water to drain rapidly. Sandy soils are prone to the leaching of nutrients and minerals and so tend to be nutritionally poor. Though most savannas are found on sites with poor soils (because of either moisture conditions or nutrient levels of both), poor soils can and do support lush rain forest. A. Their upper layers are usually sandy and porous.B. They cannot support savannas.C. They contain little oxygen.D. They are prone to the leaching of nutrients and minerals.

小马托福 010-62699622Savanna Formation

P5: Most savannas probably experience mild fires frequently and major burns every two years or so. Many savanna and dry-forest plant species are called pyrophytes, meaning they are adapted in various ways to withstand occasional burning. Frequent fire is a factor to which rain forest species seem unable to adapt, although ancient charcoal remains from Amazon forest soils dating prior to the arrival of humans suggest that moist forests also occasionally burn. Experiments suggest that if fire did not occur in savannas in the Americas, species composition would change significantly. When burning occurs, it prevents competition among plant species from progressing to the point where somespecies exclude others, reducing the overall diversity of the ecosystem. But in experimental areas protected from fire, a few perennial grass species eventually come to dominate, outcompeting all others. ■ Evidence from other studies suggests that exclusion of fire results in markedly decreased plant-species richness, often with an increase in tree density. ■There is generally little doubt that fire is a significant factor in maintaining savanna, certainly in most regions.

小马托福 010-62699622Savanna Formation

P6: ■ On certain sites, particularly in South America, savanna formation seems related to frequent cutting and burning of moist forests for pastureland. ■Increase in pastureland and subsequent overgrazing have resulted in an expansion of savanna. The thin upper layer of humus (decayed organic matter) is destroyed by cutting and burning. Humus is necessary for rapid decomposition of leaves by bacteria and fungi and for recycling by surface roots. Once the humus layer disappears, nutrients cannot be recycled and leach from the soil, converting soil from fertile to infertile and making it suitable only for savanna vegetation.

o the point where somespecies exclude others, reducing the overall diversity of the ecosystem. But in experimental areas protected from fire, a few perennial grass species eventually come to dominate, outcompeting all others. ■ Evidence from other studies suggests that exclusion of fire results in markedly decreased plant-species richness, often with an increase in tree density. ■There is generally little doubt that fire is a significant factor in maintaining savanna, certainly in most regions.

P6: ■ On certain sites, particularly in South America, savanna formation seems related to frequent cutting and burning of moist forests for pastureland. ■Increase in pastureland and subsequent overgrazing have resulted in an expansion of savanna. The thin upper layer of humus (decayed organic matter) is destroyed by cutting and burning. Humus is necessary for rapid decomposition of leaves by bacteria and fungi and for recycling by surface roots. Once the humus layer disappears, nutrients cannot be recycled and leach from the soil, converting soil from fertile to infertile and making it suitable only for savanna vegetation. Forests on white, sandy soil are most susceptible to permanent alteration.

In addition, humans have contributed to the conditions favoring the formation of savannas.

Paragraph 2: Nearly any kind of plant of the forest understory can be part of a deer's diet. 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 the black-tailed deer alive in the harsher seasons of plant decay 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 understory is exposed; also snow and wind bring down leafy branches of cedar, hemlock, red alder, and other arboreal fodder.

Paragraph 3: █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 and yet almost in the same breath bemoaned the lack of this succulent game animal. Famous explorers of the north American frontier, Lewis and Clark arrived at the mouth of the Columbia River on November 14, 1805, in nearly starved circumstances.

Extinct but already fully marine cetaceans are known from the fossil record. ■How was the gap between a walking mammal and a swimming whale bridged? ■Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans.

■Very exciting discoveries have finally allowed scientists to reconstruct the most likely origins of cetaceans. ■In 1979, a team looking for fossils in northern Pakistan found what proved to be the oldest fossil whale. The fossil was officially named Pakicetus in honor of the country where the discovery was made. Pakicetus was found embedded in rocks formed from river deposits that were 52 million years old. The river that formed these deposits was actually not far from an ancient ocean known as the Tethys Sea. 

12. This is a question that has puzzled scientists for ages.

13.Other important occasions are school graduations and weddings.

Another explanation for the focus on animals might be that these people 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 having 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. █

13 . Therefore, if the paintings were connected with hunting, some other

explanation is needed.
