2024年托福阅读句子插入题如何衔接.doc

托福阅读句子插入题怎样做到无缝衔接朗阁海外考试研究中心 郑虹句子插入题(Insert Text Questions)是托福阅读考试必考题型，出目前每一篇文章倒数第二题，大部分考生在做此题时遇到模棱两可的答案情况较多，轻易选错。朗阁海外考试研究中心的教授将针对这个问题，详细分析句子插入题的考试特点及解题技巧。一、题型特点句子插入题顾名思义就是给一句新的句子，要求考生们把这个句子插入到对应的位置，指定位置是文章中四个黑色方块的地方。这些方块分布在句首或句末，四个方框有时都出目前一个段落里，有时分布在一段的末尾和下一段的开头。考题形式如下：Look at the four squares that indicate where the following sentence could be added to the passage.Where would the sentence best fit?同学们要做的是点击其中的一个方块并将这个句子插入文章。句子插入题考查的内容是句子与句子间的逻辑关系，即所插入句子必须和前后句子在逻辑关系上保持一致。其实和我们写作同样，同学们不能把两句毫无关系的句子放在一起。那么在英语里为了体现句与句之间的逻辑关系，会采取各种衔接伎俩将句子连接起来，因此我们只要熟悉各种句子衔接伎俩，我们就能立即判断出来句子所插入的对应位置。如下，我们将对考试中常常出现的几个衔接伎俩进行详细分析。二、解题措施1. 词重复合用这种衔接措施简单粗暴明了，无需花费大量脑细胞，完全是送分题。背面一个句子里重复使用前面句子提到的同一个词（一般是名词），使用此措施，我们能够清楚懂得作者仍然在谈论同一主题，因为前后句子在乎义上关系亲密，相互连贯。Their competition and collaboration were creating the broadcasting industry in the United States, beginning with the introduction of commercial radio programming in the early 1920s. With financial assets considerably greater than those in the motion picture industry, and perhaps a wider vision of the relationships among entertainment and communications media, they revitalized research into recording sound for motion pictures. In 1929 the United States motion picture industry released more than 300 sound filmsa rough figure, since a number were silent films with music tracks, or films prepared in dual versions, to take account of the many cinemas not yet wired for sound. At the production level, in the United States the conversion was virtually complete by 1930. In Europe it took a little longer, mainly because there were more small producers for whom the costs of sound were prohibitiveLook at the four squares that indicate where the following sentence could be added to the passage.When this research resulted in the development of vastly improved sound techniques, film studios became convinced of the importance of converting to sound.前面一句话已经提及到了research, 第二次出现用this research, 因此答案选第二个选项。So, in another set of experiments, Kramer put identical food boxes around the cage, with food in only one of the boxes. The boxes were stationary, and the one containing food was always at the same point of the compass. However, its position with respect to the surroundings could be changed by revolving either the inner cage containing the birds or the outer walls, which served as the background. As long as the birds could see the Sun, no matter how their surroundings were altered, they went directly to the correct food box. Whether the box appearedLook at the four squares that indicate where the following sentence could be added to the passage.He arranged the feed boxes at various positions on a compass.不定冠词a compass在第一句话里再次出现用的是特指the compass, 因此答案选第一个黑框。2. 词指替代换带有代词题型也比较简单明了，为了防止重复，我们一般会在第二个句子使用代词替代前面（或者背面）提到过的事物（一个词）或者事件（一句话）。因此同学们只要正确找到代词所指就能做对此题。形式一般是this + 名词，或者this单独用于指代前面一句话。Since 1980, the use of wind to produce electricity has been growing rapidly. In 1994 there were nearly 20,000 wind turbines worldwide, most grouped in clusters called wind farms that collectively produced 3,000 megawatts of electricity. Most were in Denmark (which got 3 percent of its electricity from wind turbines) and California (where 17,000 machines produced 1 percent of the states electricity, enough to meet the residential needs of a city as large as San Francisco). In principle, all the power needs of the United States could be provided by exploiting the wind potential of just three statesNorth Dakota, South Dakota, and Texas. Look at the four squares that indicate where the following sentence could be added to the passage.Some companies in the power industry are aware of this wider possibility and are planning sizable wind-farm projects in states other than California.代词this wider possibility这种愈加广泛的也许性指代上一句话中的情态动词could be,情态动词could be在这里表示也许性，因此答案选最后一个选项。Under very cold conditions, rocks can be shattered by ice and frost. Glaciers may form in permanently cold areas, and these slowly moving masses of ice cut out valleys, carrying with them huge quantities of eroded rock debris. In dry areas the wind is the principal agent of erosion. It carries fine particles of sand, which bombard exposed rock surfaces, thereby wearing them into yet more sand. Even living things contribute to the formation of landscapes. Tree roots force their way into cracks in rocks and, in so doing, speed their splitting. In contrast, the roots of grasses and other small plants may help to hold loose soil fragments together, thereby helping to prevent erosion by the wind.Look at the four squares that indicate where the following sentence could be added to the passage.Under different climatic conditions, another type of destructive force contributes to erosion.another是不定代词，指代后一句提到的另外一个destructive force。通过整个段落分析，第一句话destructive force包括ice和frost, 第二句话另外一个destructive force指代的是wind, 因此选第一个黑框。阅读中常出现的代词：this, this+n, these, another, such and other etc.3. 词同义替代此类句子衔接的措施是指所插入句子里面的词（一般是名词）与所在位置前后句子的词同义替代，这种措施要求会比较高，考生除了要了解插入句子里面词的意思，还要找到所在段落里面与它同义的词。Watts 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.Look at the four squares that indicate where the following sentence could be added to the passageThe factories did not have to go to the streams when power could come to the factories这个句子里面的factories与前一句里的industry同义替代，这里同义替代并不是指两个词要完全对等才能同义替代。只要两个词之间在某一部分是表同义的就能够。例如说工业必然会包括到诸多工厂建立，因此我们能够说两个词是同义替代。答案选第三个黑框。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 fossilsSmith was able to put all the 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 was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna.Look at the four squares that indicate where the following sentence could be added to the passage.The findings of these geologists inspired others to examine the rock and fossil records in different parts of the world.The findings意思是“发觉”，与段落第二句话the same discovery表同义替代，因此这句话应当放在第三块黑框回指前文提到的发觉，答案选第三块黑框。4. 连接词衔接英语里面体现句与句之间的逻辑关系一般会用到连接词，同学们除了要懂得连接词的意思，还要懂得连接的两个句子是否存在对应的逻辑关系，因此这种措施相对前面几个是比较难的。常考连接词有表转折，原因，成果，递进等。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, 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. Look at the four squares that indicate where the following sentence could be added to the passage.However, some modern architectural designs, such as those using folded plates of concreter or air-inflated structures, are again unifying skeleton and skin.插入句子中的however表示转折，前后意思相反或者对比。最后一句话in early architecture对应插入句子modern architectural designs, 因此选择最后一个黑色方框。句子插入题常常出现的转折关系词有：however, but, yet, whereas and while etc.Because they are always swimming, tunas simply have to open their mouths and water is forced in and over their gills. Accordingly, they have lost most of the muscles that other fishes use to suck in water and push it past the gills. In fact, tunas must swim to breathe. They must also keep swimming to keep from sinking, since most have largely or completely lost the swim bladder, the gas-filled sac that helps most other fish remain buoyant.Look at the four squares that indicate where the following sentence can be added to the passage.Consequently, tunas do not need to suck in water.Consequently是表示成果的逻辑关系词。整句话意思是因此金枪鱼不需要在水里吮吸。段落第一句意思：因为金枪鱼的游动从不停止，它们必须张着嘴使水流经它们的腮。依照两句话的逻辑意思，因为它张着嘴使水流经它们的腮，因此不需要在水里吮吸。同学们不但要了解consequently的意思，还要了解前后两句话的意思才能做对此题。答案选第二个黑框。表示成果的逻辑关系词有：consequently, therefore, so, hence and thus etc.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 mid continental 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. Look at the four squares that indicate where the following sentence could be added to the passage.Moreover, other evidence suggests that even if an ice-free corridor did exist, it would have lacked the resources needed for human colonization.Moreover表递进，可译为“另外”，插入句子意思和段落最后一句话表递进关系，译为：他令人信服地主张那样的不冻地带直到很久以后才出现，那时大陆冰块开始最后的消退。另外其他证据表白虽然不冻地带存在，因此答案选最后一个黑色方框。5. 观点+例子这种连接的措施往往插入的句子是作者体现的观点，那么我们只要回段落找有关的例子就能够选择正确的方框了。The differences in feeding preferences lead, in turn, to differences in migratory habits. The wildebeests follow, in their migration, the pattern of local rainfall. The other species do likewise. But when a new area is fueled by rain, the mammals migrate toward it in a set order to exploit it. The larger, less fastidious feeders, the zebras, move in first; the choosier, smaller wildebeests come later; and the smallest species of all, Thomsons gazelle, arrives last.Look at the four squares that indicate where the following sentence could be added to the passage.The sequence in which they migrate correlates with their body size.插入的句子体现了一个观点：它们迁移的次序是与身体大小有关的。那么我们只要找一个例子和身体大小有关的句子即可。最后一句话the larger, less fastidious feeders, the zebras, move in first. 通过这两组词我们就能够判断出来这是一个例子，因此答案选最后一个黑框。Chinese porcelain wares imported into the Arab world. So admired were these pieces that they encouraged the development of earthenware made in imitation of porcelain and instigated research into the method of their manufacture. From the Middle East the Chinese acquired a blue pigmenta purified form of cobalt oxide unobtainable at that time in Chinathat contained only a low level of manganese. Cobalt ores found in China have a high manganese content, which produces a more muted blue-gray color. In the seventeenth century, the trading activities of the Dutch East India Company resulted in vast quantities of decorated Chinese porcelain being brought to Europe, which stimulated and influenced the work of a wide variety of wares, notably Delft. The Chinese themselves adapted many specific vessel forms from the West, such as bottles with long.Look at the four squares that indicate where the following sentence could be added to the passage.Foreign trade was also responsible for certain innovations in coloring.这句话也是观点：外贸也是颜色创新的原因。那么例子只要包括到颜色，外贸即可。第二句话谈到：Middle East and blue, 因此答案是第二个黑色方框。三、总结句子与句子之间的连接，重要是通过以上五种措施进行的，因此我们在做题时，先分析所给的插入句子，找出句子里面的名词，代词，连接词，其次要了解这些核心词的意思，假如不了解其意思，虽然找出来，有时候也协助不大，因此同学们不但需要技巧还需要扎实的基本功，例如词汇了解，句子结构分析的能力。
