小马公开课 小马公开课网址: 细节类题目的一般解题步骤 1. 读题 定位更准 规避干扰选项

小马公开课 小马公开课网址: 例题: According to paragraph 2, which of the following principles of ecosystems can be learned by studying a pond? ○ Ecosystem properties change more slowly than individuals in the system. ○ The stability of an ecosystem tends to change as individuals are replaced. ○ Individual organisms are stable from one year to the next. ○ A change in the members of an organism does not affect an ecosystem’s properties.

小马公开课 小马公开课网址: Paragraph 2: An ecologist who studies a pond today may well find it relatively unchanged in a year’s time. Individual fish may be replaced, but the number of fish will tend to be the same from one year to the next. We can say that the properties of an ecosystem are more stable than the individual organisms that compose the ecosystem.

小马公开课 小马公开课网址: 例题: Paragraph 1 suggests that one reason Egyptian art is viewed less favorably than other art is that Egyptian art lacks ○ a realistic sense of human body proportion ○ a focus on distinctive forms of varying sizes ○ the originality of European art ○ the capacity to show the human body in motion

小马公开课 小马公开课网址: In fact, a lack of understanding the purposes of Egyptian art has often led it to be compared unfavorably with the art of other cultures: Why did the Egyptians not develop sculpture in which the body turned and twisted through space like classical Greek statuary?

小马公开课 小马公开课网址: 例题: According to paragraph 2, all of the following are reasons why Americans migrated westward EXCEPT the desire to move from one place to the next the hope of improving their socioeconomic status the opportunity to change jobs the need to escape religious or political crises

小马公开课 小马公开课网址: Paragraph 2: Why were these hundreds of thousands of settlers—most of them farmers, some of them artisans—drawn away from the cleared fields and established cities and villages of the East? Certain characteristics of American society help to explain this remarkable migration. The European ancestors of some Americans had for centuries lived rooted to the same village or piece of land until some religious, political, or economic crisis uprooted them and drove them across the Atlantic. Many of those who experienced this sharp break thereafter lacked the ties that had bound them and their ancestors to a single place. Moreover, European society was relatively stratified; occupation and social status were inherited. In American society, however, the class structure was less rigid; some people changed occupations easily and believed it was their duty to improve their social and economic position. As a result, many Americans were an inveterately restless, rootless, and ambitious people. Therefore, these social traits helped to produce the nomadic and daring settlers who kept pushing westward beyond the fringes of settlement. In addition, there were other immigrants who migrated west in search of new homes, material success, and better lives.

As a result, many Americans were an inveterately restless, rootless, and ambitious people. the desire to move from one place to the next the hope of improving their socioeconomic status the opportunity to change jobs

小马公开课 小马公开课网址: 例题: According to paragraph 6, each of the following methods has been used in attempts to control Spanina EXCEPT flooding plants cutting plants down repeatedly applying herbicides introducing predatory insects

小马公开课 小马公开课网址: Paragraph 6: Efforts to control Spartina outside its natural environment have included burning, flooding, shading plants with black canvas or plastic, smothering the plants with dredged materials or clay, applying herbicide, and mowing repeatedly. Little success has been reported in New Zealand and England; Washington State’s management program has tried many of these methods and is presently using the herbicide glyphosphate to control its spread. Work has begun to determine the feasibility of using insects as biological controls, but effective biological controls are considered years away. Even with a massive effort, it is doubtful that complete eradication of Spartina from nonnative habitats is possible, for it has become an integral part of these shorelines and estuaries during the last 100 to 200 years. 1.flooding plants ; 2.cutting plants down repeatedly ; 3.applying herbicides ; 4.introducing predatory insects

小马公开课 小马公开课网址: 例题: According to paragraph 3, scholars explained chips in the painted figures of animals by proposing that ○ Upper Paleolithic artists used marks to record the animals they had seen ○ the paintings were inspired by the need to increase the supply of animals for hunting ○ the artists had removed rough spots on the cave walls ○ Upper Paleolithic people used the paintings to increase their luck at hunting

小马公开课 小马公开课网址: Paragraph 3: The subjects of the paintings are mostly animals. The paintings rest on bare walls, with no backdrops or environmental trappings. Perhaps, like many contemporary peoples, Upper Paleolithic men and women believed that the drawing of a human image could cause death or 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 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.

小马公开课 小马公开课网址: 例题: According to paragraph 2, why are Egyptian statues portrayed frontality? ○ To create a psychological effect of distance and isolation ○ To allow them to fulfill their important role in ceremonies of Egyptian life ○ To provide a contrast to statues with a decorative function ○ To suggest the rigid, unchanging Egyptian philosophical attitudes

小马公开课 小马公开课网址: Paragraph 2: The majority of three-dimensional representations, whether standing, seated, or kneeling, exhibit what is called frontality: they face straight ahead, neither twisting nor turning. When such statues are viewed in isolation, out of their original context and without knowledge of their function, it is easy to criticize them for their rigid attitudes that remained unchanged for three thousand years. Frontality is, however, directly related to the functions of Egyptian statuary and the contexts in which the statues were set up. Statues were created not for their decorative effect but to play a primary role in the cults of the gods, the king, and the dead.

小马公开课 小马公开课网址: 句子简化题 Which of the following best expresses the essential information in the highlighted sentence? Incorrect answer choices change the meaning in important ways or leave out essential information. 理解句意 + 抓取主干

小马公开课 小马公开课网址: 错误选项特征 1. 出现原句未提及的信息,或与原句信息相反; 2. 逻辑颠倒:因果倒置、让步转折倒置 3. 只包含次要信息

小马公开课 小马公开课网址: 错误一 The amount of air exchanged is even lower in REM than NREM because, although breathing is more rapid in REM, it is also more irregular, with brief episodes of shallow breathing or absence of breathing. A. Because breathing is more shallow and irregular in REM than in NREM, less air is exchanged in REM B. Breathing in NREM is less effective than breathing in REM because of irregular episodes of rapid breathing during NREM. C. Because breathing is more rapid in NREM sleep than in REM sleep, breathing often becomes shallow.

小马公开课 小马公开课网址: 错误二 Estimates indicate that the aquifer contains enough water to fill Lake Huron, but unfortunately, under the semiarid climatic conditions that presently exist in the region, rates of addition to the aquifer are minimal, amounting to about half a centimeter a year. ○ Despite the current impressive size of the Ogallala aquifer, the region’s climate keeps the rates of water addition very small. ○ Although the aquifer has been adding water at the rate of only half a centimeter a year, it will eventually accumulate enough water of fill Lake Huron.

小马公开课 小马公开课网址: 错误三 It is significant that the earliest living things that built communities on these islands are examples of symbiosis, a phenomenon that depends upon the close cooperation of two or more forms of life and a principle that is very important in island communities. ○ Symbiosis-the close cooperation of pairs or small groups of living organisms-is especially important in these island environments. ○ The first organisms on these islands worked together closely in a relationship known as symbiosis, which is particularly important on islands.

小马公开课 小马公开课网址: 特别注意! 原句: Some scholars expand on this idea by emphasizing a corresponding need for arable land to feed growing numbers of people: construction of small dams, reservoirs, terraces, and field houses indicates that farmers were intensifying their efforts during the 1200s. As densities increased, domestic architecture became larger, culminating in crowded pueblos.

小马公开课 小马公开课网址: A. Some scholars even claim that the intensification of farmers' various efforts during the 1200s led to further population growth and the consequent need for more arable land B. Evidence of intensifying agriculture in the 1200s indicates a need to feed a larger population and so extends the argument that a growing population was the cause of the move to pueblos C. During the 1200s, farmers met the demand for more arable land, but they also succeeded in cultivating existing land more intensively with the help of agricultural construction projects D. Some scholars feel strongly that the construction of small dams, reservoirs, terraces and field houses in the thirteenth century is independent evidence for growth in the number of people.

小马公开课 小马公开课网址: Paragraph 2: Continued sedimentation—the process of deposits’ settling on the sea bottom—buries 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 oil 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 sediment. █ Unless something acts to halt this migration, these natural resources will eventually reach the surface.

小马公开课 小马公开课网址: Paragraph 1: It has long been accepted that the Americas were colonized by a migration of peoples from Asia, slowly traveling across a land bridge called Beringia (now the Bering Strait between northeastern Asia and Alaska) during the last Ice Age. ■ The first water craft theory about the migration was that around 11,000-12,000 years ago there was an ice-free corridor stretching from eastern Beringia to the areas of North America south of the great northern glaciers. It was the midcontinental corridor between two massive ice sheets-the Laurentide to the west-that enabled the southward migration. ■ But belief in this ice-free corridor began to crumble when paleoecologist Glen MacDonald demonstrated that some of the most important radiocarbon dates used to support the existence of an ice-free corridor were incorrect. ■ He persuasively argued that such an ice-free corridor did not exist until much later, when the continental ice began its final retreat. ■ Moreover, other evidence suggests that even if an ice-free corridor did exist, it would have lacked the resources needed for human colonization.

小马公开课 小马公开课网址: Paragraph 5: Above the tree line there is a zone that is generally called alpine tundra. █ Immediately 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 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 altitude of 6,180 meters.

小马公开课 小马公开课网址: Paragraph 3: █ Watt‘s steam engine soon showed what it could do. █ It liberated 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 discovered in a millennium and a half. The factories did not have to go to the streams when power could come to the factories .

小马公开课 小马公开课网址: 修辞目的题 1. 不一定是例子 2. 观点位置不一定在前面 3. 选择与原文为同意替换的选项

小马公开课 小马公开课网址: 注意一 例题: Why does the author use the phrase Note the word "net" in the passage? ○ To emphasize the impact of seepage on water levels ○ To point out that seepage is calculated differently from river flows and atmospheric exchanges ○ To compare the different methods of calculating seepage ○ To emphasize the difficulty of obtaining specific values for seepage inputs and outputs

小马公开课 小马公开课网址: Note the word "net": measuring the actual amounts of groundwater seepage into the lake and out of the lake is a much more complicated matter than merely inferring their difference. To emphasize the difficulty of obtaining specific values for seepage inputs and outputs

小马公开课 小马公开课网址: 例题: In paragraph1, why does the author mention “the pressure of the overlying rock”? To show how water can be forced deep under Earth’s surface To show why groundwater is more plentiful than surface freshwater To correct a commonly made error about the location of groundwater To explain why most groundwater lies near Earth’s surface

小马公开课 小马公开课网址: There is more than 50 times as much freshwater stored underground than in all the freshwater rivers and lakes of Earth. At greater depths within Earth, the pressure of the overlying rock causes pores and cracks to close, reducing the space that water can occupy, and almost complete closure occurs at a depth of about 10 kilometers. The greatest water storage, therefore, lies near the surface.

小马公开课 小马公开课网址: 关键就是替换! 例题: In paragraph 2, what is the author’s purpose in presenting the information about the decision by Meyer and Mendeleyev to leave gaps in the periodic table? ○ To illustrate their confidence that the organizing principles of the periodic table would govern the occurrence of all chemical elements ○ To indicate that some of their analyses of periodic physical and chemical properties were later found to be wrong ○ To support the idea that they were unwilling to place new elements in the periodic table ○ To indicate how they handled their disagreement about where to place new elements

小马公开课 小马公开课网址: When the German chemist Lothar Meyer and (independently) the Russian Dmitry Mendeleyev first introduced the periodic table in , one-third of the naturally occurring chemical elements had not yet been discovered. Yet both chemists were sufficiently farsighted to leave gaps where their analyses of periodic physical and chemical properties indicated that new elements should be located. Mendeleyev was bolder than Meyer and even assumed that if a measured atomic mass put an element in the wrong place in the table, the atomic mass was wrong.
