Early Children Education
Preschools—educational programs for children under the age of five—differ significantly from one country to another according to the views that different societies hold regarding the purpose of early childhood education. For instance, in a cross-country comparison of preschools in China, Japan, and the United States, researchers found that parents in the three countries view the purpose of preschools very differently. Whereas parents in China tend to see preschools primarily as a way of giving children a good start academically,Japanese parents view them primarily as a way of giving children the opportunity to be members of a group. In the United States, in comparison, parents regard the primary purpose of preschools as making children more independent and self-reliant, although obtaining a good academic start and having group experience are also important.
While many programs designed for preschoolers focus primarily on social and emotional factors, some are geared mainly toward promoting cognitive gains and preparing preschoolers for the formal instruction they will experience when they start kindergarten.In the United Stated, the best-known program designed to promote future academic success is Head Start. Established in the 1960s when the United States declared the War on Poverty, the program has served over 13 million children and their families. The program, which stresses parental involvement, was designed to serve the “whole child”,including children’s physical health, self-confidence, social responsibility, and social and emotional development.
Whether Head Start is seen as successful or not depends on the lens through which one is looking. If, for instance, the program is expected to provide long-term increases in IQ (intelligence quotient) scores, it is a disappointment. Although graduates of Head Start programs tend to show immediate IQ gains, these increases do lot last. On the other hand,it is clear that Head Start is meeting its goal of getting preschoolers ready for school. Preschoolers who participate in Head Start are better prepared for future schooling than those who do not. Furthermore, graduates of Head Start programs have better future school grade. Finally, some research suggests that ultimately Head Start graduates show higher academic performance at the end of high school, although the gains are modest.
In addition, results from other types of preschool readiness programs indicate that those who participate and graduate are less like to repeat grades, and they are more like to complete school than readiness program, for every dollar spent on the program,taxpayers saved seven dollars by the time the graduated reached the age of 27.
The most recent comprehensive evaluation of early intervention programs suggests that, taken as a group, preschool programs can provide significant benefits, and that government funds invested early in life may ultimately lead to a reduction in future costs.For instance, compared with children who did not participate in early intervention programs, participants in various programs showed gains in emotional or cognitive development, better educational outcomes, increased economic self-sufficiency, reduced levels of criminal activity, and improved health-related behaviors. Of course, not every program produced all these benefits, and not every child benefited to the same extent. Furthermore, some researchers argue that less-expensive programs are just as good as relatively expensive ones, such as Head Start. Still, the results of the evaluation were promising, suggesting that the potential benefits of early intervention can be substantial.
Not everyone agrees that programs that seek to enhance academic skills during the preschool years are a good thing.In fact, according to developmental psychologist David Elkind , United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. Elkind argues that academic success is largely dependent upon factors out of parents’ control, such as inherited abilities and a child’s rate of maturation.Consequently, children of a particular age cannot be expected to master educational material without taking into account their current level of cognitive development.In short, children require development appropriate educational practice,which is education that is based on both typical development and the unique characteristics of a given child.

Extinction Episodes of the Past
【1】It was not until the Cambrian period, beginning about 600 million years ago, that a great proliferation of macroscopic species occurred on Earth and produced a fossil record that allows us to track the rise and fall of biodiversity. Since the Cambrian period, biodiversity has generally risen, but there have been some notable exceptions. Biodiversity collapsed dramatically during at least five periods because of mass extinctions around the globe. The five major mass extinctions receive most of the attention, but they are only one end of a spectrum of extinction events. Collectively, more species went extinct during smaller events that were less dramatic but more frequent. The best known of the five major extinction events, the one that saw the demise of the dinosaurs, is the Cretaceous-Tertiary extinction.
【2】Starting about 280 million years ago, reptiles were the dominant large animals in terrestrial environments. In popular language this was the era “when dinosaurs ruled Earth,” when a wide variety of reptile species occupying many ecological niches. However, no group or species can maintain its dominance indefinitely, and when, after over 200 million years, the age of dinosaurs came to a dramatic end about 65 million years ago, mammals began to flourish, evolving from relatively few types of small terrestrial animals into the myriad of diverse species, including bats and whales, that we know today. Paleontologists label this point in Earth’s history as the end of the Cretaceous period and the beginning of the Tertiary period, often abbreviated as the K-T boundary. This time was also marked by changes in many other types of organisms. Overall, about 38 percent of the families of marine animals were lost, with percentages much higher in some groups Ammonoid mollusks went from being very diverse and abundant to being extinct. An extremely abundant set of planktonic marine animals called foraminifera largely disappeared, although they rebounded later. Among plants, the K-T boundary saw a sharp but brief rise in the abundance of primitive vascular plants such as ferns, club mosses, horsetails, and conifers and other gymnosperms. The number of flowering plants (angiosperms) was reduced at this time, but they then began to increase dramatically.
【3】What caused these changes? For many years scientists assumed that a cooling of the climate was responsible, with dinosaurs being particularly vulnerable because, like modern reptiles, they were ectothermic (dependent on environmental heat, or cold-blooded). It is now widely believed that at least some species of dinosaurs had a metabolic rate high enough for them to be endotherms (animals that maintain a relatively consistent body temperature by generating heat internally). Nevertheless, climatic explanations for the K-T extinction are not really challenged by the ideas that dinosaurs may have been endothermic, because even endotherms can be affected by a significant change in the climate.
【4】Explanations for the K-T extinction were revolutionized in 1980 when a group of physical scientists led by Luis Alvarez proposed that 65 million years ago Earth was stuck by a 10-kilometer-wide meteorite traveling at 90,000 kilometers per hour. They believed that this impact generated a thick cloud of dust that enveloped Earth, shutting out much of the incoming solar radiation and reducing plant photosynthesis to very low levels. Short-term effects might have included huge tidal waves and extensive fires. In other words, a series of events arising from a single cataclysmic event caused the massive extinctions. Initially, the meteorite theory was based on a single line of evidence. At locations around the globe, geologists had found an unusually high concentration of iridium in the layer of sedimentary rocks that was formed about 65 million years ago. Iridium is an element that is usually uncommon near Earth’s surface, but it is abundant in some meteorites. Therefore, Alvarez and his colleagues concludedthat it was likely that the iridium in sedimentary rocks deposited at the K-T boundary had originated in a giant meteorite or asteroid. Most scientist came to accept the meteorite theory after evidence came to light that a circular formation, 180 kilometers in diameter in diameter and centered on the north coast of the Yucatan Peninsula, was created by a meteorite impact about 65 million years ago.

【1】For years historians have sought to identify crucial elements in the eighteenth-century rise in industry, technology, and economic power known as the Industrial Revolution, and many give prominence to the problem of energy. Until the eighteenth century, people relied on energy derived from plants as well as animal and human muscle to provide power. Increased efficiency in the use of water and wind helped with such tasks as pumping, milling, or sailing. However, by the eighteenth century, Great Britain in particular was experiencing an energy shortage. Wood, the primary source of heat for homes and industries and also used in the iron industry as processed charcoal, was diminishing in supply. Great Britain had large amounts of coal; however, there were not yet efficient means by which to produce mechanical energy or to power machinery. This was to occur with progress in the development of the steam engine.
【2】In the late 1700s James Watt designed an efficient and commercially viable steam engine that was soon applied to a variety of industrial uses as it became cheaper to use. The engine helped solve the problem of draining coal mines of groundwater and increased the production of coal needed to power steam engines elsewhere. A rotary engine attached to the steam engine enabled shafts to be turned and machines to be driven, resulting in mills using steam power to spin and weave cotton. Since the steam engine was fired by coal, the large mills did not need to be located by rivers, as had mills that used water- driven machines. The shift to increased mechanization in cotton production is apparent in the import of raw cotton and the sale of cotton goods. Between 1760 and 1850, the amount of raw cotton imported increased 230 times. Production of British cotton goods increased sixtyfold, and cotton cloth became Great Britain’s most important product, accounting for one-half of all exports. The success of the steam engine resulted in increased demands for coal, and the consequent increase in coal production was made possible as the steam-powered pumps drained water from the ever-deeper coal seams found below the water table.
【3】The availability of steam power and the demands for new machines facilitated the transformation of the iron industry. Charcoal, made from wood and thus in limited supply, was replaced with coal-derived coke (substance left after coal is heated) as steam-driven bellows came into use for producing of raw iron. Impurities were burnt away with the use of coke, producing a high-quality refined iron. Reduced cost was also instrumental in developing steam-powered rolling mills capable of producing finished iron of various shapes and sizes. The resulting boom in the iron industry expanded the annual iron output by more than 170 times between 1740 and 1840, and by the 1850s Great Britain was producing more tons of iron than the rest of the world combined. The developments in the iron industry were in part a response to the demand for more machines and the ever-widening use of higher-quality iron in other industries.
【4】Steam power and iron combined to revolutionize transport, which in turn had further implications. Improvements in road construction and sailing had occurred, but shipping heavy freight over land remained expensive, even with the use of rivers and canals wherever possible. Parallel rails had long been used in mining operations to move bigger loads, but horses were still the primary source of power. However, the arrival of the steam engine initiated a complete transformation in rail transportation, entrenching and expanding the Industrial Revolution. As transportation improved, distant and larger markets within the nation could be reached, thereby encouraging the development of larger factories to keep pace with increasing sales. Greater productivity and rising demands provided entrepreneurs with profits that could be reinvested to take advantage of new technologies to further expand capacity, or to seek alternative investment opportunities. Also, the availability of jobs in railway construction attracted many rural laborers accustomed to seasonal and temporary employment. When the work was completed, many moved to other construction jobs or to factory work in cities and towns, where they became part of an expanding working class.

Parallel rails had long been used in mining operations to move bigger loads, but horses were still the primary source of power. ■【A】However, the arrival of the steam engine initiated a complete transformation in rail transportation, entrenching and expanding the Industrial Revolution. ■【B】As transportation improved, distant and larger markets within the nation could be reached, thereby encouraging the development of larger factories to keep pace with increasing sales. ■【C】Greater productivity and rising demands provided entrepreneurs with profits that could be reinvested to take advantage of new technologies to further expand capacity, or to seek alternative investment opportunities. ■【D】Also, the availability of jobs in railway construction attracted many rural laborers accustomed to seasonal and temporary employment. When the work was completed,many moved to other construction jobs or to factory work in cities and towns, where they became part of an expanding working class.
14. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage.

托福 阅读答案
1.目的题,读highlight所在句,说英国有煤,但没法变成能量来运行机器,选项C同时说了由煤木有能量,是正确答案。A错在不是reject,原文承认缺能量,A说反;B错在原文没讲other energy resources怎么样;D错在coal mining变成重要行业没讲。
2.以the problem of energy做关键词定位至第二句,但这句话没有内容,于是往后看,下一句讲依靠动植物和人作为能量的来源,看完这句话最大的可能是选D,但原文没说动植物和人的能源不够,所以D不对。排除法,A说风和水能没有有效利用,而原文第四句说越来越多的使用,所以A错;C跟上一题相反,错;B跟上一题相同,正确。
3.A的huge quantity of raw cotton定位至倒数第三句,说进口增加了230倍,正确,不选;B定位至第五句,说机械化越来越多,正确,不选;C的mill location定位至第四句,说mill不用在水边了,也就是C说的更多可能的位置,正确,不选;也同样在这句话里说大的mills,跟D说的相反,所以D错,选。
4.apparent in明显,所以正确答案是A的clearly seen in。词根是pare,意思是可见,想想透明transparent和appear。代入,原文讲转向不断增加的mechanization是什么样的通过进口raw cotton,紧接着后面就用数字讲进口cotton怎么怎么样,说明很显著。B帮忙和C相关明显不通。前后两句没有明显的先后关系,所以follow不通。
5.以most important export和1850做关键词定位至倒数第二句和倒数第三句,说raw cotton进口增加了230倍,cotton cloth变成了最重要的产品,占了出口的一半,所以正确答案是B的cotton cloth。注意A的raw cotton是进口的。
6.consequent结果的,所以正确答案是resulting。之前有讲蒸汽机的成功result in了煤炭需求的增加,和consequent煤炭生产的增加,需求增加当然导致生产增加,所以正确答案是A,C和D完全不对,A和B相比A更好。
7.问整段的,看首尾。首句讲1700年代瓦特发明了蒸汽机,随着越来越便宜,应用越来越广;尾句说steam engine的成功导致煤炭需求和生产的增加。MS没有正确答案,可采用排除法,首先没讲除英国之外的其他国家,所以A和B都不对,C说一个行业不能引起工业革命,原文也没讲。D正确的原因是煤炭的应用解决了能源问题,正确,不记得的话看看第一段的末尾。
8.以coke做关键词定位至第二句,讲在制铁的过程中,coke替代了charcoal,但没讲coke能干嘛,所以往下看,说impurity随着coke的使用被烧掉了,也就是除杂质,所以正确答案是C,B和D的machine没讲;A说把木头变成charcoal,原文也没说。
9.A的steam-driven bellows定位至第二句,正确,不选;B的1850s和Britain定位至第五句,说英国的产量等于其他国家产量之和,当然是最大生产国,所以B正确,不选;C的different shapes and sizes定位至第四句,正确,不选;D的price没讲,错,选。
10.initiated开始,所以正确答案是D。代入,说steam engine的到来怎么了铁路运输的彻底改变,能说得通的只有B和D。因为之前没有说到变化,所以不是加速,开始了一种全新的变化更好些。
11.以transformation in rail transportation做关键词定位至第四句和第五句,说随着transportation改善,能到达更远更大的国内市场,导致更大的销量和更大的工厂,所以正确答案是C。A的rural laborers,B的ocean shipping和D的wage原文都没有有说。
12.accustomed to习惯,所以正确答案是B,used to意思完全一样。不认识的同学看custom,风俗习惯,前面的ac前缀和后面的ed均没有实际意义。代入,说铁路建设提供的工作机会吸引了工人,这些工人是怎么样季节性迁徙的,C厌倦和D鼓励说不通。A需要和B习惯就要看词汇量了。
13.此题名词过渡不容易找,只能找到动词improve,所以正确答案非B即C。B之后有as transportation improved,也就是给出improve之后的结果,应该是先有improve后有结果,所以正确答案是B。
14.For years选项与首段第二句相反,错。The introduction选项对应最后一段,正确。An expansion选项中的outside Great Britain怎么样原文没讲,错。By 1850选项对应原文第二段和第三段,正确。Since the basic选项对应原文最后一段后半部分,正确。By the end选项中的工厂找不到工人跟上increasing sales没说,错。
托福阅读译文
【1】多年来,历史学家试图找到18世纪工业革命在工业、技术和经济领域兴起的关键因素,许多人把能源问题放在突出位置。直到18世纪,人们依靠工厂、畜力以及人力来提供动力。高效地利用水能和风能有助于完成诸如抽泵、碾磨或航海等工作。然而,到了18世纪,尤其是大不列颠却经历了能源短缺。木材,这一为家庭和工业供暖供能,同时也以加工木炭的形式被使用在钢铁工业中的主要能源,其供应量日益减少。大不列颠有大
量的煤矿;然而,还没有产生机械能或为机器提供动力的有效 方法 。这一切随着蒸汽机的改良而发生。
【2】在18世纪末期,詹姆斯?瓦特设计了一款高效且具商业利益的蒸汽机,由于其价格低廉,很快就被运用到各项工业生产之中。这款蒸汽机帮助解决了煤矿中地下水的排水问题并且提高了煤的产量,这些煤用来为别处的蒸汽机提供动力。与蒸汽机相连的旋转式发动机带动轴承转动,从而驱动机器,运用蒸汽动力纺织棉布的纺织厂随之出现。因为蒸汽机靠燃煤而驱动,一些大型棉纺织厂就不再像那些使用水力驱动机器的工厂一样必须依河而建。这种棉纺织业日益机械化的转变在棉花原料的进口和棉纺产品的销售中得到突出的体现。在1760年到1850年间,原棉的进口量增长了230倍。英国棉纺产品的生产量增加了60倍,而棉布则成了英国最重要的产品,占出口总额的一半。蒸汽机的成功带来了对煤需求量的增加,而且随着蒸汽动力泵从位于地下水位下的更深的煤层中排出水来,随之而来的煤产量的增加成为可能。
【3】蒸汽动力的可利用性以及对新机器的需求促进了钢铁工业的转型。当蒸汽驱动风箱投入到生铁生产中后,木炭这种用木材烧成因此供应量有限的物质就被焦炭(煤加热后残留的物质)替代了。随着焦炭的使用,生铁中的杂质被燃烧完,从而生产出更高质量的精炼铁。降低的成本也有助于那些能够生产不同形状和尺寸的成品铁制品的蒸汽动力轧钢厂的发展。因此导致的钢铁工业的繁荣使钢铁的年产量在1740年到1840年间增长了170多倍,到19世纪50年代,大不列颠生产的钢铁比世界其他地区生产的总和还要高。钢铁工业的发展从某种意义上说,是对更多机器的需求以及在其他工业中更广泛使用高质量铁的一种回应。
【4】蒸汽动力和钢铁带来了交通运输的革新,反过来也有着更加深远的影响。道路设施以及航海的改善已经初见成效,但是船运重型货物到陆地的费用仍然很高,即使在可以使用河流和运河的地方。平行铁轨长期以来被用于采矿作业来运输大型货物,但是马匹仍然是主要的动力来源。然而,蒸汽机的到来引发了铁路运输的彻底变革,巩固和扩大了工业革命的成果。随着交通运输的改善,全国范围内更远更大的市场可以到达,因此鼓励着大型工厂的生产与日益增长的销售量保持同步。更大规模的生产和日益增长的需求给企业家带来了利润,这种利润可用于再投资新技术,进一步扩大产能或寻求其他的投资机会。同时,铁道建设方面的更多就业机会也吸引了那些习惯于季节性工作或者短工制的农村劳动力。一旦工作完成,其中的很多人就会参与到其他的建筑工作中或是城镇中的工厂工作中,并成为其中的不断壮大的工人阶级。

The Geologic History of the Mediterranean
In 1970 geologists Kenneth J. Hsu and William B.F. Ryan were collecting research data while aboard the oceanographic research vessel Glomar Challenger. An objective of this particular cruise was to investigate the floor of the Mediterranean and to resolve questions about its geologic history. One question was related to evidence that the invertebrate fauna (animals without spines) of the Mediterranean had changed abruptly about 6 million years ago. Most of the older organisms were nearly wiped out, although a few hardy species survived. A few managed to migrate into the Atlantic. Somewhat later, the migrants returned, bringing new species with them. Why did the near extinction and migrations occur?
Another task for the Glomar Challenger's scientists was to try to determine the origin of the domelike masses buried deep beneath the Mediterranean seafloor. These structures had been detected years earlier by echo-sounding instruments, but they had never been penetrated in the course of drilling. Were they salt domes such as are common along the United States Gulf Coast, and if so, why should there have been so much solid crystalline salt beneath the floor of the Mediterranean?
With question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered a sample. The sample consisted of pebbles of hardened sediment that had once been soft, deep-sea mud, as well as granules of gypsum and fragments of volcanic rock. Not a single pebble was found that might have indicated that the pebbles came from the nearby continent. In the days following, samples of solid gypsum were repeatedly brought on deck as drilling operations penetrated the seafloor. Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats. Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions. As they drilled into the central and deepest part of the Mediterranean basin, the scientists took solid, shiny, crystalline salt from the core barrel. Interbedded with the salt were thin layers of what appeared to be windblown silt.
The time had come to formulate a hypothesis. The investigators theorized that about 20 million years ago, the Mediterranean was a broad seaway linked to the Atlantic by two narrow straits. Crustal movements closed the straits, and the landlocked Mediterranean began to evaporate. Increasing salinity caused by the evaporation resulted in the extermination of scores of invertebrate species. Only a few organisms especially tolerant of very salty conditions remained. As evaporation continued, the remaining brine (salt water) became so dense that the calcium sulfate of the hard layer was precipitated. In the central deeper part of the basin, the last of the brine evaporated to precipitate more soluble sodium chloride (salt). Later, under the weight of overlying sediments, this salt flowed plastically upward to form salt domes. Before this happened, however, the Mediterranean was a vast desert 3,000 meters deep. Then, about 5.5 million years ago came the deluge. As a result of crustal adjustments and faulting, the Strait of Gibraltar, where the Mediterranean now connects to the Atlantic, opened, and water cascaded spectacularly back into the Mediterranean. Turbulent waters tore into the hardened salt flats, broke them up, and ground them into the pebbles observed in the first sample taken by the Challenger. As the basin was refilled, normal marine organisms returned. Soon layer of oceanic ooze began to accumulate above the old hard layer.
The salt and gypsum, the faunal changes, and the unusual gravel provided abundant evidence that the Mediterranean was once a desert.

参考翻译:地中海的地质历史
1970年,地理学家Kenneth J. Hsu 和 William B.F. Ryan在海洋调查船Glomar Challenger号上收集调研资料。这次特别巡航的一个目的是调查地中海的地层以及解决关于其地质历史的问题。其中一个问题是有关地中海地区无脊椎动物(没有脊椎的动物)于600万年前发生剧变的证据。大部分更加古老的生物都几乎灭绝了,尽管一些顽强的种类得以生存。很少的一些动物成功地迁移到了大西洋。不久后,这些动物又回来了,并带回来新的物种。为什么这次较近的动物灭绝和迁移会发生呢?
Glomar Challenger号上科学家们的另一个任务是尝试去确定深埋在地中海海底穹顶状巨块的起源。这些结构在早些年被回声探测器探测过,但是它们从未被钻探过。它们是像美国墨西哥海湾海岸一带的含盐穹顶状巨块吗?如果是的话,为什么在地中海海底之下会有这么多固体的结晶盐呢?
带着这些清楚摆在他们面前的问题,科学家们登上Glomar Challenger号前往地中海寻找答案。1970年8月23日,他们找到了一个样本。这个样本由石膏块和火山岩碎块组成。周围没有发现一块能说明这些小石头来自附近的大陆。接下来的日子里,随着海底岩层钻探实验的进行,固体石膏样本被不断地放在甲板上。而且,这些膏状物的组成和结构特性表明它们形成于沙漠。在石膏层上下的沉积物中包含了微小的海洋生物化石,说明了这是开放性的海洋环境。当钻到地中海盆地中心的最深处时,科学家们从钻管中获得了坚实的、光亮的结晶盐。跟结晶盐嵌在一起的薄层像是被风吹起的泥沙层。
时间阐明了一个假设。调查者们构思了这样的理论:大约2 000万年前,地中海是一条宽阔的航道,它通过两条狭窄的海峡与大西洋连接。地壳运动封闭了海峡,被陆地包围的地中海也开始蒸发。由蒸发引起的越来越高的盐度造成无脊椎动物种类的灭绝。只有一些能抵抗高盐度条件的物种保留下来。随着蒸发的继续进行,盐水浓度太高以致硬地层的硫酸钙发生沉淀。在盆地的中间深处,剩余盐水的持续蒸发形成更多的可溶的氯化钠(盐)。后来,在上层沉淀物的重压下,盐向上形成了含盐的圆顶。然而在这之前,地中海是一个3 000米深的大沙漠。然后,550万年前发生了洪水。作为地壳调整和断层作用的结果,现在连接地中海和大西洋的直布罗陀海峡打开了,水流像瀑布一样壮观地涌回地中海。湍急的水流冲击并摧毁了坚硬的含盐层,把它们磨成了Challenger号获得的第一份样本中人们所观察到的鹅卵石。随着盆地的填充,普通的海洋生物又回来了。不久后海洋软泥层开始在原先的硬地层上堆积。
盐、石膏、动物区系的变更,还有不寻常的沙砾层都为地中海曾经是片沙漠的理论提供了充分的证据。
