part A

being in a good mood decreases the brain's working memory， us researchers say.

“this explains why you might not be able to remember a phone number you get at a party when you are having a good time，” elizabeth martin， a doctoral student of psychology at the university of missouri，says in a statement. “this research is the first to show that positive mood can negatively impact working memory storage capacity.”

the researchers gauged study participants’ mood before and after showing them a video clip - some saw a bit of a stand-up comedy routine， while others saw a video on how to install flooring.

those who viewed the comedy routine were in significantly better moods after viewing the video， while the mood of flooring group had not changed. both groups were then given a memory test.

the study， published in the journal cognition and emotion， found those who watched the comedy routine performed significantly worse on the task.

美国研究人员称，好心情可能会降低大脑的工作记忆(属程序性记忆、短时记忆，是一种短暂时刻的知觉)能力。

“这就能解释为什么明明在派对上玩得很开心，却记不住从派对上得到的电话号码，”密苏里大学心理学博士伊丽莎白马丁在一份报告中指出。“该研究首次说明，积极情绪有损于工作记忆容量。”

研究人员在受试者观看视频片段前后对其情绪进行了测量。其中一部分受试者所看的是轻松喜剧节目，另一些人所看的视频则关于如何铺地板。

那些看了喜剧的受试者观后情绪更佳，而“地板视频”受试者观前观后情绪并无波动。两组都接受了记忆测试。

此项刊登于《认知与情感》杂志的研究发现，观看了喜剧的受试者在记忆测试中表现明显差于另一组受试者。

part B

打字错误是谁都难以避免的，但是据最新研究得出的结论是，我们的手指能感应到打字正确与否。

whether you're a hunt-and-peck typist or a rachmaninoff of the keyboard, you will make mistakes. but it's not just your eyes catching typos when you see them on the screen. your hands know when you mess up too. that’s according to a study in the journal science. [gordon logan and matthew crump, "cognitive illusions of authorship reveal hierarchical error detection in skilled typists"]

researchers recruited expert typists—college students, of course—and showed them 600 five-letter words, one at a time. and they asked the students to type those words as quickly and accurately as possible. but sometimes, the researchers inserted typos in the word as it appeared on screen, when the students hadn’t made one. other times they automatically corrected typos the students did make.

and the students tended to believe the screen. so if a typo had been added, they figured they must have messed up. if a typo had been corrected they thought they typed it right. but the hands didn't fall for it. when the fingers slipped up, they paused a split second longer than usual before typing the next letter. but they didn't pause when fake typos appeared on-screen only. so we apparently have two discrete mechanisms guarding against typing errors, one visual, the other tactile. to fox quick brown fixes. to fix quick brown foxes.

托福(TOEFL)考试阅读模拟试题(4)

托福（TOEFL）考试阅读模拟试题（4） Questions 11-20 Philosophy in the second half of the 19th century was based more on biology and history than on mathematics and physics. Revolutionary thought drifted away from metaphysics and epistemology and shifted more towards ideologies in science, politics, and sociology. Pragmatism became the most vigorous school of thought in American philosophy during this time, and it continued the empiricist tradition of grounding knowledge on experience and stressing the inductive procedures of experimental science. The three most important pragmatists of this period were the American philosophers Charles Peirce (1839-1914), considered to be the first of the American pragmatists, William James (1842-1910), the first great American psychologist, and John Dewey (1859-1952), who further developed the pragmatic principles of Peirce and James into a comprehensive system of thought that he called “experimental naturalism”, or “instrumentalism”. Pragmatism was generally critical of traditional western philosophy, especially the notion that there are absolute truths and absolute values. In contrast, Josiah Royce (1855-1916), was a leading American exponent of idealism at this time, who believed in an absolute truth and held that human thought and the external world were unified. Pragmatism called for ideas and theories to be tested in practice, assessing whether they produced desirable or undesirable results. Although pragmatism was popular for a time in Europe, most agree that it epitomized the American faith in know-how and practicality, and the equally American distrust of abstract theories and ideologies. Pragmatism is best understood in its historical and cultural context. It arose during a period of rapid scientific advancement, industrialization, and material progress; a time when the theory of evolution suggested to many thinkers that humanity and society are in a perpetual state of progress. This period also saw a decline in traditional religious beliefs and values. As a result, it became necessary to rethink fundamental ideas about values, religion, science, community, and individuality. Pragmatists regarded all theories and institutions as tentative hypotheses and solutions.

They continue to look for better ways to increase egg production and to improve chick survival rates. When parrots incubate their eggs in the wild, the temperature and humidity of the nest are controlled naturally. Heat is transferred from the bird's skin to the top portion of the eggshell, leaving the sides and bottom of the egg at a cooler temperature. This temperature gradient may be vital to successful hatching. Nest construction can contribute to this temperature gradient. Nests of loosely arranged sticks, rocks, or dirt are cooler in temperature at the bottom where the egg contacts the nesting material. Such nests also act as humidity regulators by allowing rain to drain into the bottom sections of the nest so that the eggs are not in direct contact with the water. As the water that collects in the bottom of the nest evaporates, the water vapor rises and is heated by the incubating bird, which adds significant humidity to the incubation environment. In artificial incubation programs, aviculturists remove eggs from the nests of parrots and incubate them under laboratory conditions. Most commercial incubators heat the eggs fairly evenly from top to bottom, thus ignoring the bird's method of natural incubation, and perhaps reducing the viability and survivability of the hatching chicks. When incubators are not used, aviculturists sometimes suspend wooden boxes outdoors to use as nests in which to place eggs. In areas where weather can become cold after eggs are laid, it is very important to maintain a deep foundation of nesting material to act as insulator against the cold bottom of the box. If eggs rest against the wooden bottom in extremely cold weather conditions, they can become chilled to a point where the embryo can no longer survive. Similarly, these boxes should be protected from direct sunlight to avoid high temperatures that are also fatal to the growing embryo. Nesting material should be added in sufficient amounts to avoid both extreme temperature situations mentioned above and assure that the eggs have a soft, secure place to rest. 1. What is the main idea of the passage ? (A) Nesting material varies according to the parrots' environment. (B) Humidity is an important factor in incubating parrots' eggs. (C) Aviculturists have constructed the ideal nest box for parrots. (D) Wild parrots' nests provide information useful for artificial incubation. 2. The word "They" in line 2 refers to

The ice tradegrew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by someforward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865),as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, halfthe ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston andChicago, went to families for their own use. This had become possible because a new householdconvenience, the icebox, a precursor of the modern refrigerator, had been invented. Making an efficient icebox was not as easy as we might now suppose. In the early nineteenthcentury, the knowledge of the physics of heat, which was essential to a science of refrigeration,was rudimentary. The commonsense notion that the best icebox was one that prevented the icefrom melting was of course mistaken, for it was the melting of the ice that performed the cooling.Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept theice from doing its job. Not until near the end of the nineteenth century did inventors achieve thedelicate balance of insulation and circulation needed for an efficient icebox. But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the righttrack. He owned a farm about twenty miles outside the city of Washington, for which the villageof Georgetown was the market center. When he used an icebox of his own design to transport hisbutter to market, he found that customers would pass up the rapidly melting stuff

The Extinction of the Dinosaurs million years ago) and the Paleocene period (65..C55 million years ago) in part by the types and amounts of rocks and fossils they contain or lack. Before the limit of 65 million years ago，marine 2.strata are rich in calcium carbonate due to accumulations of fossils of microscopic algae deposited on the sea floor. Above the 65-million-year limit，sea-floor sediments contain much less calcium carbonate ，and fossils of several families of mollusks are no longer found. In continental sediments ，dinosaur fossils ，though frequent before 65 million years ago ，are totally absent. By 3.contrast，new families of mammals appear，including large mammals for the first time. Scientists wondered for many years about what could have caused the dinosaurs' rapid disappearance at the end of the Cretaceous period，coming up with a great variety of theories and scenarios. For some, it could have been due to unfavorable genetic changes triggered by a dramatic increaseby a factor of 10，100，1，000 in cosmic-ray particles reaching the Earth after a supernova explosion somewhere in the neighborhood of the solar system. For these high-energy particles to affect life，they would have to get through the protective barrier of the Earth's magnetosphere ，the region of the upper atmosphere controlled by Earth's magnetic field. That could have happened if the cloud of particles from the supernova explosion reached the Earth during a period when the magnetosphere was weakened ， something that may happen when the Earth's magnetic field changes direction. And we know that the magnetic north and south poles of the Earth switch on the average twice every million years. However，this is not the only possible explanation for dinosaur destruction . 4.Other theories have raised the possibility of strong climate changes in the tropics (but they then must be explained) . Certainly，if climate changes，the changed distributions of temperature and rainfall modify the conditions that favor one ecosystem over another. The extinction of a particular family，genus，or species may result from a complicated chain of indirect causes and effects. Over thirty years ago ，scientist Carl Sagan quoted one suggestion that the demise of the dinosaurs resulted from the disappearance of a species of fern plant that was important for dinosaur digestion. Other theories involved a worldwide cold wave following the spread of a layer of cold but not very salty water in the world's oceans ，which floated on the surface because，with its low salinity，the water was less dense. 5.Proponents of another theory that remains under consideration today postulate that the extinction of the dinosaurs corresponds to a period of intense volcanic activity. It's not a question of just one or even of a thousand eruptions comparable to the explosion of Krakatoa in 1883，one of the largest volcanic events in modern times ，but rather of a prolonged period of activity. On the Deccan plateau in India，basalt (volcanic) rocks cover more than 500，000 square kilometers (nearly 200，000 square miles)，and correspond to massive lava outflows occurring precisely at the end of the Cretaceous. This sort of outflow could correspond to volcanic activity similar to the activity that drives sea-floor spreading ，with lava emerging from elongated fractures in the crust rather than from craters. 6.The volcanic convulsion that buried the Deccan plateau in lava must also have changed the composition of the atmosphere and severely affected climate. Initially，there must have been strong sudden cooling resulting from the blocking of sunlight by sulfate aerosol veils in the

2020年托福阅读模拟试题及答案（卷九）托福阅读文本： The Native American peoples of the north Pacific Coast created a highly complex maritime culture as they invented modes of production unique to their special environment. In addition to their sophisticated technical culture, they also attained one of the most complex social organizations of any nonagricultural people in the world. In a division of labor similar to that of the hunting peoples in the interior and among foraging peoples throughout the world, the men did most of the fishing, and the women processed the catch. Women also specialized in the gathering of the abundant shellfish that lived closer to shore. They collected oysters, crabs, sea urchins, mussels, abalone, and clams, which they could gather while remaining close to their children. The maritime life harvested by the women not only provided food, but also supplied more of the raw materials for making tools than did fish gathered by the men. Of particular importance for the native tool kit before the introduction of metal was the wide knife made from the larger mussel shells, and a variety of cutting edges that could be made from other marine shells. The women used their tools to process all of the fish and marine mammals brought in by the men. They cleaned the fish, and dried vast quantities of them for the winter. They sun-dried fish when practical, but

Industrialization came to the United State after 1790 as North American entrepreneurs increased productivity by reorganizing work and building factories. These innovations in manufacturing boosted output and living standards to an unprecedented extent; the average per capita wealth increased by nearly 1 percent per year — 30 percent over the course of a generation. Goods that had once been luxury items became part of everyday life. The impressive gain in output stemmed primarily from the way in which workers made goods, since the 1790's, North American entrepreneurs — even without technological improvements — had broadened the scope of the outwork system that made manufacturing more efficient by distributing materials to a succession of workers who each performed a single step of the production process. For example, during the 1820's and 1830's the shoe industry greatly expanded the scale and extend of the outwork system. Tens of thousands of rural women, paid according to the amount they produced, fabricated the "uppers" of shoes, which were bound to the soles by wage-earning journeymen shoemakers in dozens of Massachusetts towns, whereas previously journeymen would have made the entire shoe. This system of production made the employer a powerful "shoe boss" and eroded workers' control over the pace and conditions of labor. However, it also dramatically increased the output of shoes while cutting their price. For tasks that were not suited to the outwork system, entrepreneurs created an even more important new organization, the modem factory, which used power-driven machines and assembly-line techniques to turn out large quantities of well-made goods. As early as 1782 the prolific Delaware inventor Oliver Evans had built a highly automated, laborsaving flour mill driven by water power. His machinery lifted the grain to the top of the mill, cleaned it as it fell into containers known as hoppers, ground the grain into flour, and then conveyed the flour back to the top of the mill to allow it to cool as it descended into barrels. Subsequently, manufacturers made use of new improved stationary steam engines to power their mills. This new technology enabled them to build factories in the nation's largest cities, taking advantage of urban concentrations of inexpensive labor, good transportation networks, and eager customers. 1. What is the passage mainly about? (A) The difficulties of industrialization in North America (B) The influence of changes in manufacturing on the growth of urban centers (C) The rapid speed of industrialization in North America (D) Improved ways of organizing the manufacturing of goods 2. The word "boosted" in line 3 is closest in meaning to (A) ensured (B) raised (C) arranged (D) discouraged 3. The word "scope" in line 9 is closest in meaning to (A) value
