微观组织英语Microscopic Organization of EnglishThe English language, with its vast and intricate vocabulary, complex grammar structures, and diverse dialects, is a testament to the remarkable complexity of human communication. At the microscopic level, the organization of the English language is a fascinating study, revealing the intricate interplay of sounds, symbols, and structures that give rise to this global means of expression.At the most fundamental level, the English language is composed of individual sounds, known as phonemes. These basic units of speech are the building blocks of words, and the combination and manipulation of phonemes allow for the creation of a vast array of lexical items. The English language boasts a relatively large inventory of phonemes, with around 44 distinct sounds that can be combined in various ways to form the words we use.These phonemes are represented in written English through a system of letters, known as the Roman alphabet. The 26 letters of this alphabet, when combined in specific patterns, form the words that we recognize and utilize in our daily lives. The relationship betweenthe spoken sounds and their written counterparts is not always straightforward, however, as the English language has a complex system of orthography that can sometimes defy the expected correspondence between letters and sounds.Delving deeper into the microscopic organization of English, we find that the language is structured around a hierarchical system of units. At the most basic level, individual phonemes are combined to form morphemes, which are the smallest meaningful units of language. Morphemes can be further grouped into words, which are the primary building blocks of sentences and discourse.Words themselves can be broken down into smaller components, known as morphemes, which are the smallest units of meaning within a language. These morphemes can be root words, prefixes, or suffixes, and the combination and manipulation of these elements allow for the creation of new words and the expression of complex ideas.The grammatical structure of the English language is another important aspect of its microscopic organization. English utilizes a system of parts of speech, such as nouns, verbs, adjectives, and adverbs, which are combined according to specific rules to form coherent sentences and paragraphs. These grammatical structures, while often complex, provide the framework for the clear andeffective communication of ideas.At the level of syntax, the English language follows a relatively rigid word order, with the typical structure of a sentence being subject-verb-object. This consistency in sentence structure, combined with the use of function words like articles, prepositions, and conjunctions, helps to ensure that the meaning of a message is conveyed clearly and unambiguously.The lexical diversity of the English language is another remarkable feature of its microscopic organization. English has a vast vocabulary, with estimates ranging from 500,000 to over 1 million words, many of which have been borrowed from other languages over the course of the language's history. This rich lexical landscape allows for the precise and nuanced expression of ideas, emotions, and concepts, and contributes to the language's versatility and adaptability.The study of the microscopic organization of English also reveals the dynamic nature of the language. Words are constantly being added, modified, or removed from the language, reflecting the evolution of human thought and the changing societal and cultural contexts in which the language is used. The processes of word formation, including derivation, compounding, and blending, further contribute to the ongoing expansion and diversification of the English vocabulary.In conclusion, the microscopic organization of the English language is a complex and fascinating subject of study. From the basic building blocks of phonemes and morphemes, to the intricate structures of grammar and syntax, the language is a testament to the remarkable capacity of the human mind to create and manipulate systems of communication. By understanding the microscopic details of English, we can gain deeper insights into the nature of language itself, and appreciate the remarkable achievements of the countless individuals who have contributed to the development and evolution of this global means of expression.。
英语二小作文第二段In the second paragraph of an English composition, it is crucial to expand on the ideas introduced in the opening paragraph while providing further detail and development of the main points. Here's a structured approach to craftingthis section:1. Topic Sentence: Begin with a topic sentence that clearly states the primary focus of the paragraph. This sentence should be directly related to the thesis statement and should guide the reader on what to expect in the subsequent sentences.2. Supporting Details: Following the topic sentence, present at least two or three supporting details that reinforce the main idea. These can be facts, statistics, examples, anecdotes, or quotes that are relevant and specific.3. Explanation and Analysis: After presenting the supporting details, it's important to explain how these details support the main idea. Analyze the significance of the details and how they contribute to the overall argument or narrative of the essay.4. Transition: If the paragraph is long or complex, it may be helpful to include transitional phrases to guide the reader through the different parts of the paragraph. These can also be used to connect the ideas within the paragraph to thebroader essay.5. Coherence and Clarity: Ensure that the paragraph is coherent and that each sentence logically follows the previous one. Clarity is key; avoid ambiguity and ensure that the paragraph is easy to understand.6. Paragraph Unity: Every sentence in the paragraph should contribute to the main idea stated in the topic sentence. Avoid including information that is not directly related to the main point.Here's an example of a second paragraph for a composition on the importance of environmental conservation:"Environmental conservation is not only crucial for the survival of various species but also for the health of our planet. The increasing rate of deforestation, for instance, has led to a significant loss of habitat for many wildlife species, pushing them towards extinction. Moreover, the destruction of forests contributes to climate change by reducing the planet's ability to absorb carbon dioxide. Studies have shown that intact forests act as carbon sinks, playing a vital role in regulating the Earth's temperature. By protecting these ecosystems, we are not only safeguarding biodiversity but also combating global warming and its devastating effects on human societies."This paragraph follows the structure outlined above, providing a clear topic sentence, supporting details, and acoherent argument that builds upon the main idea introduced in the first paragraph.。
宏观概念的英语作文Title: Exploring Macroscopic Concepts。
In the realm of economics, the notion of scarcity stands as a foundational macroscopic concept. Scarcity refers to the inherent limitation of resources relative to the unlimited wants and needs of individuals and society. This fundamental principle underscores the necessity of choice, as individuals and societies must prioritize their desires due to the finite nature of resources.Furthermore, the concept of opportunity cost emerges from the phenomenon of scarcity. Opportunity cost represents the value of the next best alternative foregone when a choice is made. It embodies the concept that every decision involves trade-offs, as allocating resources to one activity necessarily means forgoing potential benefits from alternative uses of those resources. Understanding opportunity cost is crucial for rational decision-making, both at the individual and societal levels.Another macroscopic concept central to economics is the principle of supply and demand. Supply refers to the quantity of a good or service that producers are willing and able to offer for sale at various prices within a given time period. Conversely, demand represents the quantity of a good or service that consumers are willing and able to purchase at various prices within the same time frame. The interaction of supply and demand determines the equilibrium price and quantity in a market, reflecting the balance between what producers are willing to supply and what consumers are willing to demand.Moreover, elasticity serves as a key macroscopic concept in understanding the responsiveness of quantity demanded or supplied to changes in price or other determinants. Price elasticity of demand measures the percentage change in quantity demanded relative to a percentage change in price, providing insights into consumer sensitivity to price fluctuations. Similarly, price elasticity of supply assesses the percentage changein quantity supplied in response to a percentage change inprice, indicating producer responsiveness to price changes. Elasticity plays a crucial role in pricing strategies, resource allocation, and policy formulation.Moving beyond economics, the macroscopic concept of entropy originates from the field of thermodynamics. Entropy represents the measure of disorder or randomness in a system. According to the second law of thermodynamics, the entropy of an isolated system tends to increase over time, implying a natural tendency towards disorder. This concept has profound implications in various disciplines, including physics, chemistry, biology, and environmental science. Understanding entropy enables scientists and engineers to predict the direction of natural processes, design efficient energy systems, and comprehend the complexities of biological systems.In the domain of sociology, the macroscopic concept of social stratification examines the hierarchical arrangement of individuals and groups within a society based on factors such as wealth, power, and social status. Social stratification reflects unequal access to resources,opportunities, and privileges, influencing life chances and outcomes for different segments of the population. This macroscopic concept sheds light on patterns of inequality, mobility, and social cohesion, informing policies aimed at promoting social justice and equality.Furthermore, in the field of psychology, the macroscopic concept of cognitive dissonance explores the psychological discomfort that arises from holding conflicting beliefs, attitudes, or behaviors. Cognitive dissonance theory posits that individuals are motivated to reduce this discomfort by either changing their beliefs or behaviors, seeking out information that supports their existing beliefs, or rationalizing their choices. Understanding cognitive dissonance provides insights into decision-making processes, attitude formation, and behavior change interventions.In conclusion, macroscopic concepts encompass fundamental principles that underpin various disciplines, offering valuable insights into the complexities of the world around us. From economics to thermodynamics,sociology to psychology, these concepts provide frameworks for understanding phenomena at a broad scale, guiding analysis, interpretation, and application in diverse contexts. Embracing these macroscopic concepts enables individuals to navigate the intricacies of their respective fields and contribute to the advancement of knowledge and society as a whole.。

TPO 14 听力原文Conversation 1Narrator:Listen to a conversation between a student and the librarian employee.Student:Hi, I am looking for this book---the American judicial system. And I can’t seem to findit anywhere. I need to read a chapter for my political science class.Librarian:Let me check in the computer. Um… doesn’t seem to be checked out and it’s not onreserve. You’ve checked the shelves I assume.Student:Yeah, I even checked other shelves and tables next to where the book should be.Librarian:Well, it’s still here in the library. So people must be using it. You know this seems tobe a very popular book tonight. We show six copies. None are checked out. And, yetyou didn’t even find one copy on the shelves. Is it a big class?Student:Maybe about Seventy Five?Librarian:Well, you should ask your professor to put some of the copies on reserve. You knowabout the ‘Reserve system’, right?Student:I know that you have to read reserve books in the library and that you have timelimits. But I didn’t know that I could ask a professor to put a book on the reserve. Imean I thought the professors make that kind of decisions at the beginning of the semester.Librarian:Oh… they can put books on reserve at anytime during the semester.Student:You know reserving book seems a bit unfair. What if someone who is not in the classwants to use the book?Librarian:That’s why I said some copies.Student:Ah, well, I’ll certainly talk to my professor about it tomorrow. But what I am gonna dotonight?Librarian:I guess you could walk around the Poli-Sci ----- ‘Political Science’ section and look atthe books waiting to be re-shelved.Student:There are do seem to be more than normal.Librarian:We are a little short of staff right now. Someone qui t recently, so things aren’t gettingre-shelved as quickly as usual. I don’t think they’ve hired replacement yet, so, yeah,the un-shelved books can get a bit out of hand.Student:This may sound a bit weird. But I’ve been thinking about getting a job. Um… I’venever worked at the library before, But…..Librarian:That’s not a requirement. The job might still be open. At the beginning of the semester we were swamped with applications, but I guess everyone who wants thejob has one by now.Student:What can you tell me about the job?Librarian:Well, we work between six and ten hours a week, so it’s a reasonable amount.Usually we can pick the hours we want to work. But since you’d be starting so late inthe semester, I’m not sure how that would work for you. And… Oh… we get paid thenormal university rates for student employees.Student:So who do I talk to?Librarian:I guess you talk to Dr. Jenkins, the head librarian. She does the hiring.TPO 14 Lecture 1 PsychologyNarrator:Listen to part of a lecture in a psychology classProfessor:We’ve said that the term “Cognition” refers to mental states like: knowing and believing, and to mental processes that we use to arrive at those states. So forexample, reasoning is a cognitive process, so it’s perc eption. We use information thatwe perceive through our senses to help us make decisions to arrive at beliefs and soon. And then there are memory and imagination which relate to the knowledge of things that happen in the past and may happen in the future. So perceiving,remembering, imagining are all internal mental processes that lead to knowing or believing. Yet, each of these processes has limitations, and can lead us to hold mistaken believes or make false predictions. Take memory for example, maybe youhave heard of studies in which people hear a list of related words. Ah…, let`s say a listof different kinds of fruit. After hearing this list, they are presented with several additional words. In this case, we`ll say the additional words were “blanket” and “cheery”. Neither of these words was on the original list, and, well, people will claimcorrectly that “blanket” was not on the original list, they’ll also claim incorrectly thatthe word “cheery” was on the list. Most people are convinced they heard the word “cheery” on the original list. Why do they make such a simple mistake? Well, we think because the words on the list were so closely related, the brain stored only thegist of what they heard. For example, that all the items on the list were types of thefruit. When we tap our memory, our brains often fill in details and quite often thesedetails are actually false. We also see this “fill-in” phenomenon with perception.Perception is the faculty that allows us to process information in the present as we take it via our senses. Again, studies have shown that people will fill in informationthat they thought they perceived even when they didn`t. For example, experimentshave been done where a person hears a sentence, but it is missing the word, that lo gically completes it. They’ll claim to hear that word even though it was never said.So if I were to say…er…the sunrise is in the…and then fill to complete the sentence,people will often claim to have heard the word “east”.In cognitive psychology, we hav e a phrase for this kind of inaccurate “filling in of details”--- it’s called: A Blind Spot. The term originally refers to the place in our eyeswhere the optic nerve connects the back of the eye to the brain. There are no photoreceptors in the area where the nerve connects to the eye. So that particular area ofthe eye is incapable of detecting images. It produces “A Blind Spot” in our field vision.We are unaware of it, because the brain fills in what it thinks belongs in its image, sothe picture always appears complete to us. But the term “blind spot” has also takenon a more general meaning--- it refers to people being unaware of a bias that may affect their judgment about the subject. And the same “blind-spot phenomenon”that affects memory and perception also affects imagination. Imagination is a facultythat some people use to anticipate future events in their lives. But the ease with which we imagine details can lead to unrealistic expectations and can bias our decisions.So…er…Peter, suppose I ask you to image a lunch salad, no problem, right? But I betyou imagine specific ingredients. Did yours have tomatoes, Onion, Lettuce? mine did?Our brains fill in all sorts of details that might not be part of other people’s image of asalad, which could lead to disappointment for us. If the next time we order a salad ina restaurant, we have our imagined salad in mind, that’s not necessarily what we’llget on our plate. The problem is not that we imagine things, but that we assume what we’ve imagined is accu rate. We should be aware that our imagination has thisbuilt-in feature, the blind spot, which makes our predictions fall short of reality.TPO 14 Lecture 2 BiologyNarrator:Listen to part of a lecture in a biology class.Professor:Almost all animals have some way of regulating their body temperature; otherwisethey wouldn’t survive extreme hot or cold conditions---sweating, panting, swimmingto cooler or warmer water; ducking into somewhere cool like a burrow or a hole under a rock; these are just a few. And that’s body is colder or warmer than the surrounding environment, because it’s a microclimate.A microclimate is a group of climate conditions that affect the localized area, weatherfeatures like temperature, wind, moisture and so on. And when I say localized, I mean really localized, because microclimates can be, as the name suggests, pretty small, even less than a square meter. And microclimates are affected by hugenumber of other variables. Obviously weather conditions in the surrounding areas are a factor. But other aspects of the location like, um… the elevation of the land, theplant life nearby, and so on, have a substantial effect on microclimates. And of coursethe human development in the area, eh, a road will affect a nearby microclimate. It’salso interesting to know that microclimates thither or near each other can have verydifferent conditions. In the forest for example, there can be a number of verydifferent microclimates close to each other, because of all the variables I justmentioned.Student:So how does a hole in the ground, a burrow, stay cool in a hot climate?Professor:Well, since cold air sinks, and these spots are shaded, they are usually much coolerthan the surrounding area. And these spots are so important because many animalsrely on microclimates to regulate their body temperature. Hmm, for instance, there isa species of squirrel, in the Western part of the United States that can get really hotwhen they were out foraging for food. So they need a way to cool down. So what’dthey do? They go back to their own burrow. Once they get there, their bodytemperatures decrease very, very quickly. The trip to the burrow prevents thesquirrel from getting too hot.Student:But squirrels are mammals, right? I thought mammals regulate their temperature internally.Professor:Mammals do have the ability to regulate their body temperature, but not all can do itto the same degree, or even the same way. Like when you walk outside on a hot day,you perspire, and your body cools itself down, a classic example of how mammal regulates its own body temperature. But one challenge that squirrels face, well manysmall mammals do, is that because of their size, sweating would make them lose toomuch moisture. They dehydrate. But on the other hand, their small size allows themto fit into very tiny spaces. So for small mammals, microclimates can make a big difference. They rely on microclimates for survival.Student:So cold blood animals, like reptiles, they can’t control their own body temperature,so I can image the effect of microclimate would have on them.Professor:Yes, many reptile insects rely on microclimates to control their body temperature. Alot of reptiles use burrows or stay under rocks to cool down. Of course with reptiles,it’s a balancing act. Staying in the heat for too long can lead to problems, but stayingin the cold can do the same. So reptiles have to be really precise about where they spend their time, even how they position their bodies. And when I say the y’reprecise, I mean it--- some snakes will search out a place under rocks of a specific thickness, because too thin a rock doesn’t keep them cool enough, and too thick a rock will cause them to get too cold. That level of precision is critical to the snake formaintaining its body temperature. And even microscopic organisms rely onmicroclimates for survival.Think about this, decomposing leaves create heat that warms the soil; the warm soilin turn affects the growth, the conditions of organisms there. And those organisms then affect the rate of decomposition of the leaves. So a microclimate can besomething so small and so easily to disturbed that even a tiny change can have a bigimpact. If someone on a hike knocks a couple of rocks over, they could be unwittinglydestroying a microclimate that an animal or organism relies on.TPO 14 Conversation 2Narrator:Listen to a conversation between a student and his faculty adviserAdvisor:Hi ，Steven I schedule this appointment, cause it has been a while since we touch this.Student:I know I have been really busy--- a friend of my works on a school a paper. Heasksme if I would like to try to reporting so I did and I really love it.Advisor:Hey…that's sounds great!Student:Yeah… the first article I wrote it was profile of the chemistry professor---the one whose name teacher the year. My article ran on the front page. When I saw my name, I mean my byline in print, I was hooked. Now I know this is what I want to do--- be a reporter.Advisor:Isn't it great to discover something that you really enjoy? And I read that the articletoo? It was very good.Student:To be honest, the articles got a lot of editing. In fact I barely recognized a couple ofparagraphs. But the editor explained why the changes were made. I learned a lot andmy second article didn't meet nearly many changes.Advisor:Sound like you got a real neck for this.Student:Yeah… anyway, I am glad you schedule this meeting because I want to change mymajor to journalism now.Advisor:Um，the university doesn't offer major in journalism.Student:Oh no…Advisor:But….Student:I… I mean… should I transfer to another school, or major in English?Advisor:Er… wait a minute. Let me explain why the major isn’t offered. Editors at t he newspaper… editors… um… I mean when you apply for a reporting job, editors lookat the two things--- they want to see clips, you know, some of your published articles,though also want to try out, though give you an assignment like… covering a price ofconferences some other event, then see if you can craft the story about it, accurately,on dead line.Student:So they don't even to look at my major?Advisor:It is not that they don't look at it… it is… well, having a degree in something otherthan journalism should actually work to your advantage.Student:How?Advisor:Most journalism specialized these days. They only write about science or business ortechnology for example. Is there a type of reporting you think you may like to specialize then?Student:Well… I think it can be really cool to cover the Supreme Court. I mean… theirdecisionaffects so many people.Advisor:That is really a goal worth striving for. So, why not continue major in political science?And as elective, you could take some Pre-Law classes like Constitution Law, and asfor you work on the student newspaper paper, maybe they let you cover some localcourt cases--- once that the student and professor here would want to read about.Student:Do you know of any？Advisor:I do. Actually, there is case involving this computer software program that one of ourprofessors wrote. The district courts decide in if the university entitle to any of ourprofessors' profits?Student:Wah…. I will definitely follow upon that!TPO 14 Lecture 3 AstronomyNarrator:Listen to part of a lecture in an astronomy class.Professor:OK, last time we talked about ancient agricultural civilizations that observed the starsand then used those observations to keep track of the seasons. But today I want to talk about the importance of stars for early seafarers, about how the fixed patterns of stars were used as navigational aids.OK, you’ve all heard about the Vikings and their impressive navigation skills, but theseafaring people of the pacific islands, the Polynesians and the Micronesians,werequite possibly the world’s greatest navigators. Long before the development of, uh,advanced navigational tools in Europe, pacific islanders were travelling from NewZealand to Hawaii and back again, using nothing but the stars as their navigationalinstruments.Um, the key to the pacific islanders’ success was probably their location near the equator. What that meant was that the sky could be partitioned, divided up, much more symmetrically than it could farther away from the equator. Unlike the Vikings,early observers of the stars in Polynesia or really anywhere along the equator wouldfeel that they were at the very center of things, with the skies to the north and the skies to the south behaving identically, they could see stars going straight up in theeast and straight down in the west. So it was easier to discern the order in the sky than farther north or farther south, where everything would seem more chaotic.Take the case of the Gilbert Islands, they are part of Polynesia, and lie very close tothe equator. And the people there were able to divide the sky into symmetrical boxes,according to the main directions, north, east, south and west. And they couldprecisely describe the location of a star by indicating its position in one of those imaginary boxes. And they realized that you had to know the stars in order tonavigate. In fact there was only one word for both in the Gilbert Islands, when youwanted to the star expert, you ask for a navigator.Um, islanders from all over the pacific learned to use the stars for navigation, and they passed this knowledge down from generation to generation. Some of them utilized stone structures called stone canoes, ah, and these canoes were on land, ofcourse, and you can still see them on some islands today. They were positioned as ifthey were heading in the direction of the points on the sea horizon where certain stars would appear and disappear during the night, and, um, young would-benavigators set by the stones at night and turned in different directions to memorizethe constellations they saw, so they could recognize them and navigate… by them later on when they went out to sea.One important way the Polynesians had for orienting themselves was by using zenithstars. A zenith star was a really bright star that would pass directly overhead atparticular latitude…at a particular distance from the equator, often at a latitude associate with some particular pacific island. So the Polynesians could estimate theirlatitude just by looking straight up, by observing whether a certain zenith star passeddirectly overhead at night, they’d know if they have rates the same latitude as a particular island they were trying to get to. Um, another technique used by the Po lynesians was to look for a star pair, that’s two stars that rise at the same time, orset at the same time, and navigators could use these pairs of stars as reference points,because they rise or set together only at specific latitudes. So navigators might seeone star pair setting together. And, uh…would know how far north or south of the equator they were. And if they kept on going, and the next night they saw the pairsof stars setting separately, then they would know that they were at a different degreeof latitude. So looking at rising and setting star pairs is a good technique. Um…actually it makes more sense with setting stars; they can be watched instead of tryingto guess when they’ll rise.Uh, OK, I think all this shows that navigating doesn’t re ally require fancy navigationalinstruments; the peoples of the pacific islands had such expert knowledge ofastronomy as well as navigation that they were able to navigate over vast stretches ofOpen Ocean. Uh, it's even possible that Polynesian navigators had already sailed tothe Americas, centuries before Columbus.TPO 14 Lecture 4 ArcheologyNarrator:Listen to part of the lecture in the archaeology classProfessor:When we think of large monumental structures built by early societies and Egyptianpyramid probably comes to mind. But there are some even earlier structures in theBritish Isles also worth discussing, and besides the well-known circle of massivestones of Stonehenge which don’t get me wrong is remarkable enough, well, otherimpressive Neolithic structures are found there too. Oh, yes, we are talking about theNeolithic period here, also called new Stone Age, which was the time before stonetools began to be replaced by tools made by bronze and other metals.It was about 5000 years ago, even before the first Egyptian pyramid that some of amazing Neolithic monuments---tombs, were racketed at the very size around ironedGreat Britain and costal islands nearby.I am referring particular to structures that in some cases, look like ordinary naturalhills. But we definitely build by humans, well-organized communities of human’s toenclose a chamber or room within stone walls and sometimes with a high, cleverlydesigned sealing of overlapping stones. These structures are called Passage Graves,because in the chamber, sometime several chambers in fact, could only be entered from the outside through a narrow passage way.Michael:Excuse me, professor, but you said Passage Graves. Was this just monument to honorthe dead buried there or were they designed to be used somehow by the living?Professor:Ah, yes! Good question, Michael. Besides being built as tombs, some of these Passage Graves were definitely what we might call Astronomical Calendars, with chambers they flooded with some light on the certain special days of the year, witchmust see miraculous and inspired good dealer of they really just wonder. Butresearch indicates that not just light but also the physics of sound help to enhance this religious experience.Michael:How so?Professor:Well, first the echoes. When religious leaders started chanting with echoes bouncedoff the stonewalls over and over again, it must seem like a whole chorus of other voices, spirits of God maybe join in. But even more intriguing is what physicistscalledStanding Waves. Basically, the phenomenon of Standing Waves occurs when soundwaves of the same frequency reflect off the walls and meet from opposite directions.So, the volume seems to alternate between very loud and very soft. You can stand quite near a man singing in loud voice and hardly hear him. Yet step little further away and voice is almost defining. As you move around chamber, the volume of thesound goes way up and way down, depending on where you are and these standingwaves. And often the acoustic makes it hard to identify where sounds are coming from. It is powerful voices that are speaking to you or chanting from inside your ownhead. This had to engender powerful sense of all Neolithic worshipers.And another bit of physics I played here is something called Resonance. I know physics, but well I imagine you have all below near of top empty bottles and heardsounds it makes. And you probably notice that depending on its size--- each emptybottle plays one particular music note. Or it is the physics might put it, each bottle resonates at a particular frequency. Well, that’s true of these chambers too. If you make a constant noise inside the chamber, maybe by steadily beating drum at certainrate, a particular frequency of sound will resonate. We will ring out intensely,depending on the size of chamber. In some of large chambers though, theseintensified sound may be too deep for us to hear, we can feel it. We are mysteriouslyagitated by a….but it is not a sound our ears can hear. The psychologic al effects of allthese extraordinary sounds can be profound, especially when they seem sodisconnected from human doing drumming or chanting. And there can be observablephysical effects on people too.

This approach helps students to see the structure of the text and to distinguish between the main points and the finer details. Memorizing vocabulary (A), focusing on details (B), and practicing pronunciation (D) are all useful activities but do not directly aid in understanding the main idea of the text.These types of questions test the candidate’s knowledge of English grammar and pedagogical strategies for effective teaching.23、In the following sentence, which verb tense is used to express an action that began in the past and continues to the present?A. Present PerfectB. Simple PresentC. Present Perfect ContinuousD. Past ContinuousAnswer: C. Present Perfect ContinuousExplanation: The correct answer is C because the Present Perfect Continuoustense is used to describe actions that started in the past, continue up to the present, and may continue into the future.

If + past perfect, would + have + past participleC. If + present tense, would + verbD. If + present perfect, would + have + past participleAnswer: C. If + present tense, would + verbExplanation: The correct answer is C because the “If + present tense” structure is used to express a condition that is true in the present. This structure is used to talk about real a nd possible situations. For example, “If it rains, we will cancel the game.”25、Which of the following is NOT a strategy for teaching vocabulary in high school English classes?A) Using context clues to infer word meaningsB) Memorizing vocabulary lists without contextC) Encouraging students to use new words in their own sentencesD) Utilizing word associations and synonymsAnswer: BExplanation: Option B, “Memorizing vocabulary lists without context,” isgenerally not considered an effective strategy for teaching vocabulary in high school English classes.

Effective vocabulary instruction often involves using context clues, encouraging students to apply new words in their own sentences, and utilizing word associations and synonyms to deepen their understanding.26、In a lesson aimed at improving students’ listening comprehension, which of the following activities would be most beneficial?A) Having students read a passage silently and answer comprehension questionsB) Playing a recording of a conversation and asking students to summarize the main pointsC) Asking students to write an essay on a given topicD) Providing students with a list of vocabulary words to memorizeAnswer: BExplanation: Option B, “Playing a recording of a conversation and asking students to summarize the main points,” is the most beneficial activity in a lesson aimed at impro ving students’ listening comprehension. This activity directly addresses the skill of listening by engaging students in the process of actively listening to a recording and then analyzing and summarizing the information they heard. In contrast, option A focuses on reading comprehension, option C on writing skills, and option D on vocabulary memorization, all of whichare important but less directly related to improving listening comprehension.27、Which of the following sentences uses the subjunctive mood correctly?A)If he were here, he would help us.B)If she was younger, she could join the team.C)If they had known, they would have come.D)If I was rich, I would travel the world.Answer: A) If he were here, he would help us.Explanation: The correct form of the subjunctive mood is used in option A, where “were” is used instead of “was” for the present unreal condition. Options B and D should use “were” instead of “was,” and C is actually in the past perfect subjunctive which is correct but does not match the present hypothetical context of the question.28、Choose the correct form of the verb that agrees with the subject in the following sentence:“Either the judge or the defendants_______to appear in court tomorrow.”A)hasB)haveC)is havingD)are havingAnswer: A) hasExplanation: When the subject consists of two or more nouns connected by “or” or “either…or,” the verb agrees with the subject nearest to it. Here, “the defendants” is nearer but the singular “the judge” determines the ve rbform. Therefore, the singular form “has” is correct as “the judge” is singular.29.The teacher is about to introduce a new topic in the English class. Which of the following phrases would best signal the introduction of a new topic?A. “Let’s continue where we left off.”B. “Today, we are going to explore a new topic.”C. “Now, we need to wrap up our discussion.”D. “We’ll take a quick break before we move on.”Answer: BExplanation: The phrase “Today, we are going to explore a new topic.” clearly signals that the teacher is introducing a new topic in the lesson.30.In the context of teaching high school English, which of the following is the most effective way to encourage student participation in group discussions?A.

2019年12月大学英语六级阅读晨读美文：TheMicroscopic TechniqueThe Microscopic TechniqueEach advance in microscopic technique has provided scientists with new perspectives on the function of living organisms and the nature of matter itself. The invention of the visible light microscope late in the sixteenth century introduced a previously unknown realm of single celled plants and animals. In the twentieth century, electron microscopes have provided direct views of viruses and minuscule surface structures. Now another type of microscope, one that utilizes x rays rather than light or electrons, offers a different way of examining tiny details; it should extend human perception still farther into the natural world. The dream of building an x ray microscope dates to back 1895; its development, however was virtually halted in the 1940's because the development of the electron microscope was progressing rapidly. During the 1940's, electron microscopesroutinely achieved resolution better than that poss ible with a visible light microscope, while the performance of x ray microscopes resisted improvement. In recent years, however, interest in x ray microscopes has revived, largely because of advances such as the developmen t of new sources of x ray illumination. As a result, the brightness available today is millions of times tha t of x ray tubes, which, for most of the century, were the only available sources of soft xrays.The new x ray microscopes considerably improve on theresolution provided by optical microscopes. They can also be used to map the distribution of certain chemical elements. Some can form pictures in extremely short times; others hold the promise of special capabilities such as three dimensional imaging. Unlike conventional electron microscope, x ray microscope enables specimens to be kept in air and in water, which means that biological samples can be studied under conditions similar to their natural state. The illumination used, so called soft x rays in the wavelength range of twenty to forty angstroms (an angstrom is one ten billionth of a meter), is also sufficiently penetrating to image intact biological cells in ma ny cases. Because of the wavelength of the x rays used, soft x ray microscopes will never match the highest resolution possible with electron microscopes. Rather, their special properties will make possible investigationsthat will complement those performed with light and electron based instruments.。
