Milgram’s Study of ObedienceAims: Milgram was sceptical about the idea that only strict authoritive figures could afflict the horrors seen during World War Two by the Nazis. He wanted to prove this view held by the general public wrong, by doing an obedience experiment to show that ordinary people of the general public could inflict harm on other human beings.Procedures: 40 males aged 20-50 were recruited through a newspaper advertisement, and paid $4.50 to participate in a study regarding ’memory’. Participants were introduced to a confederate, Mr. Wallice. Lots were drawn to decide who would be the teacher and who would be the learner (the participant always became the teacher). The learner was strapped into a chair with electrodes on his hands.The participant was to ask the learner questions, each incorrect answer was punished with an electric shock, beginning at 15 volts (very mild), going up by 15 volts for every incorrect answer up to 450 volts (danger - severe shock, xxx). The learner stated he had a mild heart condition.Shocks were received in silence up until 300 volts, Mr. Wallice thencomplained of having heart trouble and pounded on the door to be let out. He then refused to answer any more questions. After a short while he became silent and was presumed unconscious or dead.If the teachers questioned the experimenter (also a confederate), they were presented with four orders:1. Please continue,2. The experiment requires you to continue,3. It is essential that you continue,4. You have no choice, you must continue.If the participant still refused to administer any more shocks, they were allowed to stop.Unknown to the participant, the experimenter was an actor, as was the learner. The lots drawn to distinguish roles were fixed, and the electric shocks WERE NOT REAL.雅思阅读V42.S2电击试验相关材料-2参考译文:服从是指按照他人命令去行动的行为,也是人际互动的基本方式之一。

4.A recent study of ancient and modern elephants has come up with the unexpected conclusion that the african elephant is divided into two disinct (不同的)species.The discovery was made by researchers at York and Harvard Universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants----the Asian elephant,African forest elephant and African savanna elephant.Once they obtained DNA sequences (序列) from two fossils (化⽯),mammoths and mastodons,the team compared them with DNA from modern elephants,they found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian ele The scientists used detailed genetic analysis to prove that the African savanna elephants and Afican forest elephants have been distinct species for several million years the divergenceof the two species took place around the time of the divergence of Asian elephants and woolly mammoths,this result amazed all the scienitstsThere has long been debate in the scientific community that the two might be separate species,but this is the most convincing scientific evidence so far that they are indeed different species.Previously,many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants'significant size differences,the savanna elelpha Alfred Roca,assistant professor in the Department of Animal Sciences at the University of Illinois,said"we now have to treat the forest and savanna elephants as two different units for conservation purpose,since 先)for conservation purposes."66.one of the fossols studied by the reaearchers if that ofDA.the Asian elephantB.the forest elephantC the savanna elephantD the mastodon elephant67.the underlined word"divergence"in paragraph 4means"C"A.evolution B.exhibition C.separation D.examination68.The researchers conclusion was based on a study of the African elephant'sAA.DNA B.height C.weight D.populalion69.What are Alfred Roca's words mainly about?AA.The conservation of African elephants.B.The purpose of studying African elephants.C.The way to divide African elephants into two units.D.The reason for the distinction of African elephants.70.Which of the following can be the best title for the passage?CA.Naturalists'Beliefs about ElephantsB.Amazing Experiment about Elephants.C.An Unexpected Finding about Elephants.D.A Long Scientist Debate about Elephants.分析本⽂为说明⽂.主要介绍了最近的⼀项研究表明⾮洲⼤象被分为两种截然不同的物种---⾮洲草原⼤象和⾮洲深林⼤象.科学家们使⽤了详细的基因剖析,来证明数百万年以来,当⾮洲草原⼤象和⾮洲深林⼤象经历不同的演化历程的同时,这两个不同的物种亦同时演化,这研究结果令科学家们感到惊讶.长期以来,科学界都存在着争论,认为这可能是两个不同的物种,⽽这发现就是迄今最有⼒的科学实证,证明牠们确实是不同的物种.解答 66.D 细节理解.根据第三段的第⼀句"Oncethey obtained DNA sequences 序列)( from two fossils(化⽯),mammoths and mastodons…"可知,研究⼈员通过化⽯提取的 DNA研究结果为"mastodons 乳齿象",故选D.67.C 词义猜测.前⾯⼀句"The scientists used detailed genetic analysis to prove that the African savanna elephants and African forest elephants have been distinct species for several million years"讲到了这两种⼤象分离成不同的物种已有数百万年了,由此可判断"divergence"在此是"分离"之意.故选C.68.A 细节理解.根据倒数第⼆段的最后⼀句"However the proof lay in the analysis of the DNA."可知,研究⼈员的结论是在检测⾮洲⼤象DNA的基础上得出来的,故选A.69.A 推理判断.根据最后⼀段的内容"Now that we know the forest and savanna elephants are two very distinctive animals,the forest elephant should become a bigger priority(优先) forconservation purposes"可知,Alfred Roca 的话主要讲的是对不同的⾮洲⼤象要分别采取不同的保护措施.70.C 主旨⼤意.根据本⽂的主题句(第⼀段)"A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的)species"可知,主要介绍了最近的⼀项研究表明⾮洲⼤象被分为两种截然不同的物种---⾮洲草原⼤象和⾮洲深林⼤象.故选 C.点评解答细节理解题时,⼀个常⽤的⽅法就是运⽤定位法,即根据题⼲和选项中的关键词从原⽂中找到相关的句⼦,与选项进⾏⽐较从⽽确定答案;推理判断题既要求学⽣透过⽂章表⾯⽂字信息推测⽂章隐含意思,⼜要求学⽣对作者的态度、意图及⽂章细节的发展作正确的推理判断,⼒求从作者的⾓度去考虑,不要固守⾃⼰的看法或观点.。

英语作文科学证据分析Scientific Evidence Analysis。

Science is a systematic and logical approach to discovering new knowledge and explaining the natural world through observation and experimentation. Scientificevidence is the data and information that supportsscientific theories and hypotheses. It is essential to analyze scientific evidence to understand its significance and implications.One of the most important steps in analyzing scientific evidence is to determine its reliability. Reliable evidence is evidence that can be trusted to be accurate and unbiased. To determine the reliability of evidence, scientists use a variety of methods such as peer review, replication, and statistical analysis. Peer review is a process in which experts in the field review and evaluate the evidence to ensure its validity. Replication is the process ofrepeating an experiment to ensure that the results areconsistent and reliable. Statistical analysis is used to determine the probability that the evidence is accurate and not due to chance.Another important step in analyzing scientific evidence is to evaluate its significance. Significant evidence is evidence that has a meaningful impact on our understanding of the natural world. To evaluate the significance of evidence, scientists consider factors such as the scope of the evidence, its relevance to current theories, and its potential for future research. They also consider the potential implications of the evidence for society and the environment.Finally, scientists must communicate their findings to the scientific community and the general public. This involves presenting the evidence in a clear and concise manner, using appropriate scientific language and terminology. Scientists must also be transparent abouttheir methods and data, and be open to criticism and feedback.In conclusion, analyzing scientific evidence is acrucial step in the scientific process. It allowsscientists to determine the reliability and significance of their findings, and communicate their discoveries to others. By using rigorous methods and being transparent about their work, scientists can ensure that their evidence is accurate and meaningful, and contributes to our understanding of the natural world.。

英语专业八级考试TEM-8阅读理解练习册(1)(英语专业2012级)UNIT 1Text AEvery minute of every day, what ecologist生态学家James Carlton calls a global ―conveyor belt‖, redistributes ocean organisms生物.It’s planetwide biological disruption生物的破坏that scientists have barely begun to understand.Dr. Carlton —an oceanographer at Williams College in Williamstown,Mass.—explains that, at any given moment, ―There are several thousand marine species traveling… in the ballast water of ships.‖ These creatures move from coastal waters where they fit into the local web of life to places where some of them could tear that web apart. This is the larger dimension of the infamous无耻的,邪恶的invasion of fish-destroying, pipe-clogging zebra mussels有斑马纹的贻贝.Such voracious贪婪的invaders at least make their presence known. What concerns Carlton and his fellow marine ecologists is the lack of knowledge about the hundreds of alien invaders that quietly enter coastal waters around the world every day. Many of them probably just die out. Some benignly亲切地,仁慈地—or even beneficially — join the local scene. But some will make trouble.In one sense, this is an old story. Organisms have ridden ships for centuries. They have clung to hulls and come along with cargo. What’s new is the scale and speed of the migrations made possible by the massive volume of ship-ballast water压载水— taken in to provide ship stability—continuously moving around the world…Ships load up with ballast water and its inhabitants in coastal waters of one port and dump the ballast in another port that may be thousands of kilometers away. A single load can run to hundreds of gallons. Some larger ships take on as much as 40 million gallons. The creatures that come along tend to be in their larva free-floating stage. When discharged排出in alien waters they can mature into crabs, jellyfish水母, slugs鼻涕虫,蛞蝓, and many other forms.Since the problem involves coastal species, simply banning ballast dumps in coastal waters would, in theory, solve it. Coastal organisms in ballast water that is flushed into midocean would not survive. Such a ban has worked for North American Inland Waterway. But it would be hard to enforce it worldwide. Heating ballast water or straining it should also halt the species spread. But before any such worldwide regulations were imposed, scientists would need a clearer view of what is going on.The continuous shuffling洗牌of marine organisms has changed the biology of the sea on a global scale. It can have devastating effects as in the case of the American comb jellyfish that recently invaded the Black Sea. It has destroyed that sea’s anchovy鳀鱼fishery by eating anchovy eggs. It may soon spread to western and northern European waters.The maritime nations that created the biological ―conveyor belt‖ should support a coordinated international effort to find out what is going on and what should be done about it. (456 words)1.According to Dr. Carlton, ocean organism‟s are_______.A.being moved to new environmentsB.destroying the planetC.succumbing to the zebra musselD.developing alien characteristics2.Oceanographers海洋学家are concerned because_________.A.their knowledge of this phenomenon is limitedB.they believe the oceans are dyingC.they fear an invasion from outer-spaceD.they have identified thousands of alien webs3.According to marine ecologists, transplanted marinespecies____________.A.may upset the ecosystems of coastal watersB.are all compatible with one anotherC.can only survive in their home watersD.sometimes disrupt shipping lanes4.The identified cause of the problem is_______.A.the rapidity with which larvae matureB. a common practice of the shipping industryC. a centuries old speciesD.the world wide movement of ocean currents5.The article suggests that a solution to the problem__________.A.is unlikely to be identifiedB.must precede further researchC.is hypothetically假设地,假想地easyD.will limit global shippingText BNew …Endangered‟ List Targets Many US RiversIt is hard to think of a major natural resource or pollution issue in North America today that does not affect rivers.Farm chemical runoff残渣, industrial waste, urban storm sewers, sewage treatment, mining, logging, grazing放牧,military bases, residential and business development, hydropower水力发电,loss of wetlands. The list goes on.Legislation like the Clean Water Act and Wild and Scenic Rivers Act have provided some protection, but threats continue.The Environmental Protection Agency (EPA) reported yesterday that an assessment of 642,000 miles of rivers and streams showed 34 percent in less than good condition. In a major study of the Clean Water Act, the Natural Resources Defense Council last fall reported that poison runoff impairs损害more than 125,000 miles of rivers.More recently, the NRDC and Izaak Walton League warned that pollution and loss of wetlands—made worse by last year’s flooding—is degrading恶化the Mississippi River ecosystem.On Tuesday, the conservation group保护组织American Rivers issued its annual list of 10 ―endangered‖ and 20 ―threatened‖ rivers in 32 states, the District of Colombia, and Canada.At the top of the list is the Clarks Fork of the Yellowstone River, whereCanadian mining firms plan to build a 74-acre英亩reservoir水库,蓄水池as part of a gold mine less than three miles from Yellowstone National Park. The reservoir would hold the runoff from the sulfuric acid 硫酸used to extract gold from crushed rock.―In the event this tailings pond failed, the impact to th e greater Yellowstone ecosystem would be cataclysmic大变动的,灾难性的and the damage irreversible不可逆转的.‖ Sen. Max Baucus of Montana, chairman of the Environment and Public Works Committee, wrote to Noranda Minerals Inc., an owner of the ― New World Mine‖.Last fall, an EPA official expressed concern about the mine and its potential impact, especially the plastic-lined storage reservoir. ― I am unaware of any studies evaluating how a tailings pond尾矿池,残渣池could be maintained to ensure its structural integrity forev er,‖ said Stephen Hoffman, chief of the EPA’s Mining Waste Section. ―It is my opinion that underwater disposal of tailings at New World may present a potentially significant threat to human health and the environment.‖The results of an environmental-impact statement, now being drafted by the Forest Service and Montana Department of State Lands, could determine the mine’s future…In its recent proposal to reauthorize the Clean Water Act, the Clinton administration noted ―dramatically improved water quality since 1972,‖ when the act was passed. But it also reported that 30 percent of riverscontinue to be degraded, mainly by silt泥沙and nutrients from farm and urban runoff, combined sewer overflows, and municipal sewage城市污水. Bottom sediments沉积物are contaminated污染in more than 1,000 waterways, the administration reported in releasing its proposal in January. Between 60 and 80 percent of riparian corridors (riverbank lands) have been degraded.As with endangered species and their habitats in forests and deserts, the complexity of ecosystems is seen in rivers and the effects of development----beyond the obvious threats of industrial pollution, municipal waste, and in-stream diversions改道to slake消除the thirst of new communities in dry regions like the Southwes t…While there are many political hurdles障碍ahead, reauthorization of the Clean Water Act this year holds promise for US rivers. Rep. Norm Mineta of California, who chairs the House Committee overseeing the bill, calls it ―probably the most important env ironmental legislation this Congress will enact.‖ (553 words)6.According to the passage, the Clean Water Act______.A.has been ineffectiveB.will definitely be renewedC.has never been evaluatedD.was enacted some 30 years ago7.“Endangered” rivers are _________.A.catalogued annuallyB.less polluted than ―threatened rivers‖C.caused by floodingD.adjacent to large cities8.The “cataclysmic” event referred to in paragraph eight would be__________.A. fortuitous偶然的,意外的B. adventitious外加的,偶然的C. catastrophicD. precarious不稳定的,危险的9. The owners of the New World Mine appear to be______.A. ecologically aware of the impact of miningB. determined to construct a safe tailings pondC. indifferent to the concerns voiced by the EPAD. willing to relocate operations10. The passage conveys the impression that_______.A. Canadians are disinterested in natural resourcesB. private and public environmental groups aboundC. river banks are erodingD. the majority of US rivers are in poor conditionText CA classic series of experiments to determine the effects ofoverpopulation on communities of rats was reported in February of 1962 in an article in Scientific American. The experiments were conducted by a psychologist, John B. Calhoun and his associates. In each of these experiments, an equal number of male and female adult rats were placed in an enclosure and given an adequate supply of food, water, and other necessities. The rat populations were allowed to increase. Calhoun knew from experience approximately how many rats could live in the enclosures without experiencing stress due to overcrowding. He allowed the population to increase to approximately twice this number. Then he stabilized the population by removing offspring that were not dependent on their mothers. He and his associates then carefully observed and recorded behavior in these overpopulated communities. At the end of their experiments, Calhoun and his associates were able to conclude that overcrowding causes a breakdown in the normal social relationships among rats, a kind of social disease. The rats in the experiments did not follow the same patterns of behavior as rats would in a community without overcrowding.The females in the rat population were the most seriously affected by the high population density: They showed deviant异常的maternal behavior; they did not behave as mother rats normally do. In fact, many of the pups幼兽,幼崽, as rat babies are called, died as a result of poor maternal care. For example, mothers sometimes abandoned their pups,and, without their mothers' care, the pups died. Under normal conditions, a mother rat would not leave her pups alone to die. However, the experiments verified that in overpopulated communities, mother rats do not behave normally. Their behavior may be considered pathologically 病理上,病理学地diseased.The dominant males in the rat population were the least affected by overpopulation. Each of these strong males claimed an area of the enclosure as his own. Therefore, these individuals did not experience the overcrowding in the same way as the other rats did. The fact that the dominant males had adequate space in which to live may explain why they were not as seriously affected by overpopulation as the other rats. However, dominant males did behave pathologically at times. Their antisocial behavior consisted of attacks on weaker male,female, and immature rats. This deviant behavior showed that even though the dominant males had enough living space, they too were affected by the general overcrowding in the enclosure.Non-dominant males in the experimental rat communities also exhibited deviant social behavior. Some withdrew completely; they moved very little and ate and drank at times when the other rats were sleeping in order to avoid contact with them. Other non-dominant males were hyperactive; they were much more active than is normal, chasing other rats and fighting each other. This segment of the rat population, likeall the other parts, was affected by the overpopulation.The behavior of the non-dominant males and of the other components of the rat population has parallels in human behavior. People in densely populated areas exhibit deviant behavior similar to that of the rats in Calhoun's experiments. In large urban areas such as New York City, London, Mexican City, and Cairo, there are abandoned children. There are cruel, powerful individuals, both men and women. There are also people who withdraw and people who become hyperactive. The quantity of other forms of social pathology such as murder, rape, and robbery also frequently occur in densely populated human communities. Is the principal cause of these disorders overpopulation? Calhoun’s experiments suggest that it might be. In any case, social scientists and city planners have been influenced by the results of this series of experiments.11. Paragraph l is organized according to__________.A. reasonsB. descriptionC. examplesD. definition12.Calhoun stabilized the rat population_________.A. when it was double the number that could live in the enclosure without stressB. by removing young ratsC. at a constant number of adult rats in the enclosureD. all of the above are correct13.W hich of the following inferences CANNOT be made from theinformation inPara. 1?A. Calhoun's experiment is still considered important today.B. Overpopulation causes pathological behavior in rat populations.C. Stress does not occur in rat communities unless there is overcrowding.D. Calhoun had experimented with rats before.14. Which of the following behavior didn‟t happen in this experiment?A. All the male rats exhibited pathological behavior.B. Mother rats abandoned their pups.C. Female rats showed deviant maternal behavior.D. Mother rats left their rat babies alone.15. The main idea of the paragraph three is that __________.A. dominant males had adequate living spaceB. dominant males were not as seriously affected by overcrowding as the otherratsC. dominant males attacked weaker ratsD. the strongest males are always able to adapt to bad conditionsText DThe first mention of slavery in the statutes法令,法规of the English colonies of North America does not occur until after 1660—some forty years after the importation of the first Black people. Lest we think that existed in fact before it did in law, Oscar and Mary Handlin assure us, that the status of B lack people down to the 1660’s was that of servants. A critique批判of the Handlins’ interpretation of why legal slavery did not appear until the 1660’s suggests that assumptions about the relation between slavery and racial prejudice should be reexamined, and that explanation for the different treatment of Black slaves in North and South America should be expanded.The Handlins explain the appearance of legal slavery by arguing that, during the 1660’s, the position of white servants was improving relative to that of black servants. Thus, the Handlins contend, Black and White servants, heretofore treated alike, each attained a different status. There are, however, important objections to this argument. First, the Handlins cannot adequately demonstrate that t he White servant’s position was improving, during and after the 1660’s; several acts of the Maryland and Virginia legislatures indicate otherwise. Another flaw in the Handlins’ interpretation is their assumption that prior to the establishment of legal slavery there was no discrimination against Black people. It is true that before the 1660’s Black people were rarely called slaves. But this shouldnot overshadow evidence from the 1630’s on that points to racial discrimination without using the term slavery. Such discrimination sometimes stopped short of lifetime servitude or inherited status—the two attributes of true slavery—yet in other cases it included both. The Handlins’ argument excludes the real possibility that Black people in the English colonies were never treated as the equals of White people.The possibility has important ramifications后果,影响.If from the outset Black people were discriminated against, then legal slavery should be viewed as a reflection and an extension of racial prejudice rather than, as many historians including the Handlins have argued, the cause of prejudice. In addition, the existence of discrimination before the advent of legal slavery offers a further explanation for the harsher treatment of Black slaves in North than in South America. Freyre and Tannenbaum have rightly argued that the lack of certain traditions in North America—such as a Roman conception of slavery and a Roman Catholic emphasis on equality— explains why the treatment of Black slaves was more severe there than in the Spanish and Portuguese colonies of South America. But this cannot be the whole explanation since it is merely negative, based only on a lack of something. A more compelling令人信服的explanation is that the early and sometimes extreme racial discrimination in the English colonies helped determine the particular nature of the slavery that followed. (462 words)16. Which of the following is the most logical inference to be drawn from the passage about the effects of “several acts of the Maryland and Virginia legislatures” (Para.2) passed during and after the 1660‟s?A. The acts negatively affected the pre-1660’s position of Black as wellas of White servants.B. The acts had the effect of impairing rather than improving theposition of White servants relative to what it had been before the 1660’s.C. The acts had a different effect on the position of white servants thandid many of the acts passed during this time by the legislatures of other colonies.D. The acts, at the very least, caused the position of White servants toremain no better than it had been before the 1660’s.17. With which of the following statements regarding the status ofBlack people in the English colonies of North America before the 1660‟s would the author be LEAST likely to agree?A. Although black people were not legally considered to be slaves,they were often called slaves.B. Although subject to some discrimination, black people had a higherlegal status than they did after the 1660’s.C. Although sometimes subject to lifetime servitude, black peoplewere not legally considered to be slaves.D. Although often not treated the same as White people, black people,like many white people, possessed the legal status of servants.18. According to the passage, the Handlins have argued which of thefollowing about the relationship between racial prejudice and the institution of legal slavery in the English colonies of North America?A. Racial prejudice and the institution of slavery arose simultaneously.B. Racial prejudice most often the form of the imposition of inheritedstatus, one of the attributes of slavery.C. The source of racial prejudice was the institution of slavery.D. Because of the influence of the Roman Catholic Church, racialprejudice sometimes did not result in slavery.19. The passage suggests that the existence of a Roman conception ofslavery in Spanish and Portuguese colonies had the effect of _________.A. extending rather than causing racial prejudice in these coloniesB. hastening the legalization of slavery in these colonies.C. mitigating some of the conditions of slavery for black people in these coloniesD. delaying the introduction of slavery into the English colonies20. The author considers the explanation put forward by Freyre andTannenbaum for the treatment accorded B lack slaves in the English colonies of North America to be _____________.A. ambitious but misguidedB. valid有根据的but limitedC. popular but suspectD. anachronistic过时的,时代错误的and controversialUNIT 2Text AThe sea lay like an unbroken mirror all around the pine-girt, lonely shores of Orr’s Island.

It was one of those hazy朦胧的, calm, dissolving days of Indian summer, when everything is so quiet that the fainest kiss of the wave on the beach can be heard, and white clouds seem to faint into the blue of the sky, and soft swathing一长条bands of violet vapor make all earth look dreamy, and give to the sharp, clear-cut outlines of the northern landscape all those mysteries of light and shade which impart such tenderness to Italian scenery.The funeral was over,--- the tread鞋底的花纹/ 踏of many feet, bearing the heavy burden of two broken lives, had been to the lonely graveyard, and had come back again,--- each footstep lighter and more unconstrained不受拘束的as each one went his way from the great old tragedy of Death to the common cheerful of Life.The solemn black clock stood swaying with its eternal ―tick-tock, tick-tock,‖ in the kitchen of the brown house on Orr’s Island. There was there that sense of a stillness that can be felt,---such as settles down on a dwelling住处when any of its inmates have passed through its doors for the last time, to go whence they shall not return. The best room was shut up and darkened, with only so much light as could fall through a little heart-shaped hole in the window-shutter,---for except on solemn visits, or prayer-meetings or weddings, or funerals, that room formed no part of the daily family scenery.The kitchen was clean and ample, hearth灶台, and oven on one side, and rows of old-fashioned splint-bottomed chairs against the wall. A table scoured to snowy whiteness, and a little work-stand whereon lay the Bible, the Missionary Herald, and the Weekly Christian Mirror, before named, formed the principal furniture. One feature, however, must not be forgotten, ---a great sea-chest水手用的储物箱,which had been the companion of Zephaniah through all the countries of the earth. Old, and battered破旧的,磨损的, and unsightly难看的it looked, yet report said that there was good store within which men for the most part respect more than anything else; and, indeed it proved often when a deed of grace was to be done--- when a woman was suddenly made a widow in a coast gale大风,狂风, or a fishing-smack小渔船was run down in the fogs off the banks, leaving in some neighboring cottage a family of orphans,---in all such cases, the opening of this sea-chest was an event of good omen 预兆to the bereaved丧亲者;for Zephaniah had a large heart and a large hand, and was apt有…的倾向to take it out full of silver dollars when once it went in. So the ark of the covenant约柜could not have been looked on with more reverence崇敬than the neighbours usually showed to Captain Pennel’s sea-chest.1. The author describes Orr‟s Island in a(n)______way.A.emotionally appealing, imaginativeB.rational, logically preciseC.factually detailed, objectiveD.vague, uncertain2.According to the passage, the “best room”_____.A.has its many windows boarded upB.has had the furniture removedC.is used only on formal and ceremonious occasionsD.is the busiest room in the house3.From the description of the kitchen we can infer that thehouse belongs to people who_____.A.never have guestsB.like modern appliancesC.are probably religiousD.dislike housework4.The passage implies that_______.A.few people attended the funeralB.fishing is a secure vocationC.the island is densely populatedD.the house belonged to the deceased5.From the description of Zephaniah we can see thathe_________.A.was physically a very big manB.preferred the lonely life of a sailorC.always stayed at homeD.was frugal and saved a lotText BBasic to any understanding of Canada in the 20 years after the Second World War is the country' s impressive population growth. For every three Canadians in 1945, there were over five in 1966. In September 1966 Canada's population passed the 20 million mark. Most of this surging growth came from natural increase. The depression of the 1930s and the war had held back marriages, and the catching-up process began after 1945. The baby boom continued through the decade of the 1950s, producing a population increase of nearly fifteen percent in the five years from 1951 to 1956. This rate of increase had been exceeded only once before in Canada's history, in the decade before 1911 when the prairies were being settled. Undoubtedly, the good economic conditions of the 1950s supported a growth in the population, but the expansion also derived from a trend toward earlier marriages and an increase in the average size of families; In 1957 the Canadian birth rate stood at 28 per thousand, one of the highest in the world. After the peak year of 1957, thebirth rate in Canada began to decline. It continued falling until in 1966 it stood at the lowest level in 25 years. Partly this decline reflected the low level of births during the depression and the war, but it was also caused by changes in Canadian society. Young people were staying at school longer, more women were working; young married couples were buying automobiles or houses before starting families; rising living standards were cutting down the size of families. It appeared that Canada was once more falling in step with the trend toward smaller families that had occurred all through theWestern world since the time of the Industrial Revolution. Although the growth in Canada’s population had slowed down by 1966 (the cent), another increase in the first half of the 1960s was only nine percent), another large population wave was coming over the horizon. It would be composed of the children of the children who were born during the period of the high birth rate prior to 1957.6. What does the passage mainly discuss?A. Educational changes in Canadian society.B. Canada during the Second World War.C. Population trends in postwar Canada.D. Standards of living in Canada.7. According to the passage, when did Canada's baby boom begin?A. In the decade after 1911.B. After 1945.C. During the depression of the 1930s.D. In 1966.8. The author suggests that in Canada during the 1950s____________.A. the urban population decreased rapidlyB. fewer people marriedC. economic conditions were poorD. the birth rate was very high9. When was the birth rate in Canada at its lowest postwar level?A. 1966.B. 1957.C. 1956.D. 1951.10. The author mentions all of the following as causes of declines inpopulation growth after 1957 EXCEPT_________________.A. people being better educatedB. people getting married earlierC. better standards of livingD. couples buying houses11.I t can be inferred from the passage that before the IndustrialRevolution_______________.A. families were largerB. population statistics were unreliableC. the population grew steadilyD. economic conditions were badText CI was just a boy when my father brought me to Harlem for the first time, almost 50 years ago. We stayed at the hotel Theresa, a grand brick structure at 125th Street and Seventh avenue. Once, in the hotel restaurant, my father pointed out Joe Louis. He even got Mr. Brown, the hotel manager, to introduce me to him, a bit punchy强力的but still champ焦急as fast as I was concerned.Much has changed since then. Business and real estate are booming. Some say a new renaissance is under way. Others decry责难what they see as outside forces running roughshod肆意践踏over the old Harlem. New York meant Harlem to me, and as a young man I visited it whenever I could. But many of my old haunts are gone. The Theresa shut down in 1966. National chains that once ignored Harlem now anticipate yuppie money and want pieces of this prime Manhattan real estate. So here I am on a hot August afternoon, sitting in a Starbucks that two years ago opened a block away from the Theresa, snatching抓取,攫取at memories between sips of high-priced coffee. I am about to open up a piece of the old Harlem---the New York Amsterdam News---when a tourist。

EXPERIMENTAL INVESTIGATION OF PRECESSION AND NUTAT

EXPERIMENTAL INVESTIGATION OF PRECESSION AND NUTAT

MechanicsSpinning MotionPrecession and Nutation of a GyroscopeEXPERIMENTAL INVESTIGATION OF PRECESSION AND NUTATION OF A GYROSCOPE AND DETERMINATION OF MOMENT OF INERTIAUE1040500 07/16 UDFig. 1: Set-up for measuring precession of a gyroscope (with no additional weight added).GENERAL PRINCIPLESA spinning top is a rigid body which spins around an axis fixed at a given point. If an external force acts upon the axis, its torque causes a change in the angular momen-tum. The top thenmoves in a direction perpendicular to the axis and the force acting upon it. Such a motion is called precession. If a top is pushed away from its axis of rotation its starts to undergo a tipping motion. This mo-tion is called nutation. In general, both these motions occur superimposed on one another.In this experiment, a gyroscope is used rather than a top. Its large rotating disc rotates with low friction about an axis which is fixed at a certain bearing point. A counterweight is adjusted in such a way that the bearing point coincides with the centre of gravity. If the gyroscope is in equilibrium and the disc is set spinning, the momentum L will be constant:(1) R L I =⋅ωI : moment of inertia, ωR : angular velocityFig. 2 Set-up for measuring nutation of a gyroscope.The moment of inertia of the rotating disc of the gyroscope is given by:(2) 212I M R =⋅⋅ M : mass of disc, R : radius of discIf extra weight is put on the axis of rotation by addition of a mass m , the additional weight causes a torque τ which changes the angular momentum:(3) d d Lm g r tτ=⋅⋅=r : Distance from bearing point of axis of rotation to wherethe weight of the additional mass actsFig. 3 Schematic of a gyroscope illustrating precession The axis of rotation then moves as shown in Fig. 3 by the following angle:(4) dL m g r dt d L L⋅⋅⋅φ== It also starts to precess.

The angular velocity of the nutation is then directly proportional to the angular velocity of the rotation:(7) N R C ω=⋅ω and R N T C T =⋅ C : constantFig. 4 Schematic of a gyroscope illustrating nutationLIST OF APPARATUS1 Gyroscope 1000695 (U52006)2 Photo Gate 1000563 (U11365)1 Laser Diode, Red 1003201 (U22000)1 3B NET log™ @230V 1000540 (U11300-230) or1 3B NET log™ @115V1000539 (U11300-115) 1 3B NET lab™1000544 (U11310)3 Tripod Stand 150 mm 1002835 (U13270)3 Universal Clamp 1002830 (U13255)3 Stainless Steel Rod 750 mm 1002935 (U15003)SETTING UP A GYROSCOPE∙Place the stand base on a level working surface which is not subject to vibration and use the spirit level to align it to the horizontal.∙Insert the stand rod into the stand base and secure it (Fig. 5, 1).∙Place the rotor head in such a way that its main axle is on the stand rod (Fig. 5, 2).∙Move the flywheel onto the main gyroscope axle as far it will go with the bobbin end facing away from the rotor head (Fig. 5, 3). Insert the spacer and secure the flywheel with the fastening disc (Fig. 5, 3). Fully unscrew the fas-tening screw at the other end of the main axis to begin with.∙First slot the large counterweight, then the small set weight onto the other end of the main axle and screw the fastening screw back into the main axle (Fig. 5, 5,6,7).Move the counterweight and set weight to make the alignment of the main axis horizontal (pointer at 0 on the scale) and secure them both with fastening screws. You may need to make some fine adjustments with the screw. Fig. 5 Setting up the gyroscope.∙Attach the pointer for the flywheel to the flywheel itself with velcro as shown in Fig. 1 and Fig. 2.SET-UP AND EXPERIMENT PROCEDURE∙Set-up the two photoelectric gates with the help of stand components such that they are positioned as in Fig. 1 and Fig. 2 and use the cable with the 8-pin miniDIN plugs to connect them to analog inputs A and B of the NET log™ unit.Note:When measuring nutation, the photo gate which records the period of nutation should not be operated in “internal light barrier mode” but in “laser light barrier mode”. This is activat-ed by closing the mechanical aperture and aligning the diode laser with the opening in the side of the photo gate.∙Turn on the computer and run 3B NET lab™. Connect the 3B NET log™ unit to the computer with the USB cable. In 3B NET lab™, click the “Test” under “Device connection”, to check the connection.∙Configure analog inputs A and B to 20 V DC in 3B NET lab™ and click the “Inputs OK” button to confirm.∙Set the following parameters:Measuring interval/Rate: 10 ms 100 Hz Osc Number of measurement values: 10000Duration of measurement: 01:40.0 sClick the “Parameters OK” button to confirm.∙For measuring precession, suspend the weight holder with three weights on it from the hole in the front end of the main axle.∙For measuring nutation do not suspend any weights.∙Insert the metal sleeve of the starter thread into the hole in the bobbin and wind the starter thread around the bob-bin.∙Press the “Start” button in 3B NET lab™ to start recording measurements.∙Grip the rear end of the main axle with one hand and hold the grip on the end of the starter thread with the other.Start the flywheel rotating by pulling fast and hard, but steadily, on the starter thread. Then immediately let go of the main axle.Note:When pulling the starter thread, keep it under tension until it has all rolled off the bobbin, otherwise it could get tangled in it.It may be best to have two people doing the starting of 3B NET lab™ and turning the flywheel.Make sure that the gyroscope remains more or less horizontal while doing this.∙For measuring nutation, get the nutation started by hitting the gyroscope axle gently from the side.SAMPLE MEASUREMENTS AND EVALUA-TIONMass M of flywheel: 1.5 kg Radius R of flywheel: 12.5 cm Mass of additional weight m: 150 g Distance r from fulcrum of axle to point from which additional weight is suspended 22.5 cm Fig. 6 (top) and Fig. 7 (top) show some typical results for precession and nutation measurements using 3B NET lab™and the set-ups shown in Fig. 1 and Fig. 2.∙Determine the periods for precession, nutation and rota-tion T P, T N and T R via the changes in the timing diagram recorded for the pulses.In Fig. 6 and Fig. 7 analog input A (blue) corresponds to the timing diagram for the rotation signal and analog input B (red) is the timing diagram for the precession or nutation signals. The period of precession can be read off directly with the help of the cursors. It is the interval between two pulses. For ex-ample, the first precession period in Fig. 6 (centre) T P = 16.52 s.The period of nutation can also be read off directly with the help of the cursors, see Fig. 7 (centre). To do this, identify at least three successive and evenly spaced pulses in the signal. Since in one period of nutation, the photo gate will be ob-scured three times, the nutation period corresponds to the interval between the first pulse and the third one. For exam-ple, the first nutation period in Fig. 7 (centre) T N = 1.64 s.The rotation period is obtained from multiple successive puls-es in the same regions where the corresponding precession or nutation periods were determined.

新药申报中的分析方法必须进行验证并有相关文件记录验证结果。

(三)建立的规范、标准、取样计划、测试程序或实验室控制程序没有被很好的执行或在执行时没有记录。

一种情况是企业在执行的过程中使用已申报的测试方法没有达到预期的结果,于是重新更改了这个方法,但没有重新申报。

另一种情况是分析员在做实验的时候自己做了变化而没有任何纪录。

(四)没有按照已经制定的书面程序中所规定的合适频率对仪器进行较正,或当仪器准确度或精确度超标时,没有采取适当的纠正措施。

如果仪器校正的结果超标,非常重要的一步就是要调查用这个仪器测试的产品会不会存在质量的隐患,会不会有不准确的结果。

(五)对于质量控制部门的职责或程序没有成文,或者没有被执行。

典型的质量控制部门的职责就是批准标准、程序,并对任何异常事件进行调查。

(六)在不合格批调查方面,对预料之外的偏差/某些批次产品或其组分不符合标准的情况的调查没有覆盖与该异常事件相关的同一产品的其它批次或其他品种。

即使结果认可被拒绝,对超标事件进行调查还是很有价值的,可以判断是不是影响到其它的相关批次。

如果结果超标了,就要确定它的根本原因。

这个原因有助于评价相关批次,即使这些相关批次结果都是在这个标准范围之内,但还是得重新评价结果是否可信。

(七)药品出厂前的测试和释放没有适当的实验室判定程序,以确保药品能最终满足产品质量标准。

二、实验室检验超标事件(OOS)调查程序。

Recent progress in the development of diesel surrogate fuels

Recent progress in the development of diesel surrogate fuels

a b s t r a c t
There has been much recent progress in the area of surrogate fuels for diesel. In the last few years, experiments and modeling have been performed on higher molecular weight components of relevance to diesel fuel such as n-hexadecane (n-cetane) and 2,2,4,4,6,8,8-heptamethylnonane (iso-cetane). Chemical kinetic models have been developed for all the n-alkanes up to 16 carbon atoms. Also, there has been experimental and modeling work on lower molecular weight surrogate components such as n-decane and n-dodecane that are most relevant to jet fuel surrogates, but are also relevant to diesel surrogates where simulation of the full boiling point range is desired. For two-ring compounds, experimental work on decalin and tetralin recently has been published. For esters, kinetic mechanisms for compounds of lower molecular weights but similar to those found in typical biodiesel blendstocks also have been published. For multi-component surrogate fuel mixtures, recent work on modeling of these mixtures and comparisons to real diesel fuel is reviewed. Detailed chemical kinetic models for surrogate fuels are very large in size, so it is noteworthy that significant progress also has been made in improving the mechanism reduction tools that are needed to make these large models practicable in multidimensional reacting flow simulations of diesel combustion. Nevertheless, major research gaps remain. In the case of iso-alkanes, there are experiments and modeling work on only one of relevance to diesel: iso-cetane. Also, the iso-alkanes in diesel are lightly branched and no detailed chemical kinetic models or experimental investigations are available for such compounds. More components are needed to fill out the iso-alkane boiling point range. For the aromatic class of compounds, there has been little work for compounds in the boiling point range of diesel. Most of the new work has been on alkyl aromatics that are of the range C7eC9, below the C10eC20 range that is needed. For the chemical classes of cycloalkanes and esters, experiments and modeling on higher molecular weight components are warranted. Finally for multi-component surrogates needed to treat real diesel, the inclusion of higher molecular weight components is needed in models and experimental investigations.

分析现象的英语作文Title: Analyzing Phenomena: Understanding and Insight。

Introduction:In the realm of academia and beyond, the art of analyzing phenomena is quintessential. It transcends disciplines, offering a systematic approach to understanding the intricacies of various occurrences. Whether scrutinizing social phenomena, economic trends, scientific breakthroughs, or cultural shifts, the process of analysis unveils layers of meaning and insight. This essay delves into the significance of analyzing phenomena and explores its methodologies and implications.Understanding the Significance:Analyzing phenomena serves as a gateway to comprehension and enlightenment. It enables individuals to decipher underlying patterns, causes, and effects within agiven context. Through rigorous examination, seemingly disparate elements coalesce into a coherent narrative, fostering a deeper understanding of the subject matter. Moreover, analysis empowers individuals to make informed decisions, formulate strategies, and devise solutions to complex problems. In essence, it is the cornerstone of critical thinking and intellectual inquiry.Methodologies of Analysis:Various methodologies are employed in the analysis of phenomena, each tailored to suit the specific nature of the subject under scrutiny. Quantitative analysis utilizes statistical tools and mathematical models to quantify and interpret data, yielding empirical insights into phenomena ranging from market trends to demographic shifts.
