下面是一篇相关的文章:(正文)Over the past few decades, the rapid development of technology has brought significant changes to our daily lives. While the advances in technology have undoubtedly made our lives more convenient and efficient, they have also had a profound impact on the environment.One major area where technology has influenced the environment is in transportation. The invention of the automobile revolutionized the way people travel, but it also led to an increase in carbon emissions and air pollution. In recent years, however, there have been promising developments in electric vehicles, which have the potential to significantly reduce pollution levels. Governments and automakers around the world are investing in the development of electric cars and the necessary infrastructure to support them. This shift towards electric transportation is a step in the right direction towards a greener future.Another area where the impact of technology on the environment is evident is in energy production. Traditional energy sources, such as coal and oil, have been responsible for a substantial amount of greenhouse gas emissions. However, advancements in renewable energy technologies, such as solar and wind power, offer a more sustainable alternative. These clean energy sources have the potential to reduce our dependency on fossil fuels and mitigate the harmful effects of climate change.In addition to transportation and energy production, technology has also influenced the way we consume and dispose of products. The rise of e-commerce has led to an increase in online shopping, which has both positive and negative implications for the environment. On one hand, online shopping reduces the need for physical stores, resulting in lower energy consumption and carbon emissions. On the other hand, the packaging and shipping of products purchased online contribute to waste and pollution. It is crucial to find a balance between the convenience of online shopping and the environmental impact it has.In conclusion, the advancements in technology have had a significant impact on the environment. While there are negative consequences, such as increased pollution and waste, there are also positive developments, such as electric vehicles and renewable energy sources. It is essential for governments, businesses, and individuals to work together to harness the benefits of technology while minimizing its harmful effects on the environment.(题目二)历史与文化2023年托福阅读真题也涉及历史与文化领域的文章,要求考生阅读文章并回答相关问题。

Language researchers say pronunciation and fluency are the biggest barriers, followed by grammar, in effective spoken English. However, most people don't regardpronunciation as a very important part of communication skills. They're more focused on vocabulary. One reason is that most people are not even aware of their mispronunciations. So it's important to first find out the words you mispronounce. You should listen to experts, by experts, I mean those who are less likely to make pronunciation mistakes. When listening to them, pay attention to words that sound strange, strange because you pronounce the same words differently. When you come across such words, check a dictionary to confirm their exact pronunciations. You can also search for difficult-to-pronounce words and names, and make a list of them. The last suggestion is to read aloud. Now you've got the correct pronunciations of the words, it's time to practice reading them every day.1. C2. C3. B4. A5. C6. A7. B8. A9. B 10. A11. C 12. B 13.

托福阅读真题练习:声音的文本+题目+答案托福阅读文本:A number of factors related to the voice reveal the personality of the speaker. The first is the broad area of communication, which includes imparting information by use of language, communicating with a group or an individual, and specialized communication through performance. A person conveys thoughts and ideas through choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, by the rhythm that is inherent within the language itself, and by speech rhythms that are flowing and regular or uneven and hesitant, and finally, by the pitch and melody of the utterance. When speaking before a group, a persons tone may indicate unsureness or fright, confidence or calm. At interpersonal levels, the tone may reflect ideas and feelings over and above the words chosen, or may belie them. Here the conversants tone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack of concern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are usually discernible by the acute listener. Public performance is a manner of communication that is highly specialized with its own techniques for obtaining effects by voice and /or gesture. The motivation derived from the text, and in the case of singing, the music, in combination with the performers skills, personality, and ability to create empathy will determine the success of artistic, political, or pedagogic communication.Second, the voice gives psychological clues to a persons self-image, perception of others, and emotional health. Self-image can be indicated by a tone of voice that is confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a few personality traits. Also the sound may give a clue to the facade or mask of that person, for example, a shy person hiding behind an overconfident front. How a speaker perceives the listeners receptiveness, interest, or sympathy in any given conversation can drastically alter the tone of presentation, by encouraging or discouraging the speaker. Emotional health is evidenced in the voice by free and melodic sounds of the happy, by constricted and harsh sound of the angry, and by dull and lethargic qualities of the depressed.托福阅读题目:1.

In December of that year, a group of thirty artists gathered in the studio of John Falconer in New York City and drafted both a constitution and bylaws, establishing The Society for the Promotion of Painting in Water Color. In addition to securing an exhibition space in the Library Society building in lower Manhattan, the society founded a small school for the instruction of watercolor painting. Periodic exhibitions of the members paintings also included works by noted English artists of the day, borrowed from embryonic private collections in the city. The societys activities also included organized sketching excursions along the Hudson River. Its major public exposure came in 1853, when the society presented works by its members in the Industry of All Nations section of the Crystal Palace Exposition in New York.The society did not prosper, however, and by the time of its annual meeting in 1854 membership had fallen to twenty-one. The group gave up its quarters in the Library Society building and returned to Falconers studio, where it broke up amid dissension. No further attempt to formally organize the growing numbers of watercolor painters in New York City was made for more than a decade. During that decade, though, Henry Warrens Painting in Water Color was published in New York City in 1856 — the book was a considerable improvement over the only other manual of instruction existing at the time, Elements of Graphic Art, by Archibald Roberson,published in 1802 and by the 1850s long out of print.In 1866 the NationalAcademy of Design was host to an exhibition of watercolor painting in its elaborate neo-Venetian Gothic building on Twenty-Third Street in New York City. The exhibit was sponsored by an independent group called The Artists Fund Society. Within a few months of this event, forty-two prominent artists living in and near New York City founded The American Society of Painters in Water Colors.托福阅读题目:1.

Evidence obtained from a site known as the Hole in the Rock, in Papago Park in Phoenix, Arizona, indicates that it might have been used as an observatory by a prehistoric people known as the Hohokam.The physical attributes of the site allow its use as a natural calendar/clock. The hole at Hole in the Rock is formed by two large overhanging rocks coming together at a point, creating a shelter with an opening large enough for several persons to pass through. The northeast-facing overhang has a smaller opening in its roof. It is this smaller hole that produces the attributes that may have been used as a calendar/clock.Because of its location in the shelters roof, a beam of sunlight can pass through this second hole and cast a spot onto the shelters wall and floor. This spot of light travels from west to east as the sun moves across the sky. It also moves from north to south and back again as the Earth travels around the Sun, the west-to-east movement could have been used to establish a daily clock, much like a sundial, while the north-to-south movement could have been used to establish a seasonal calendar.The spot first appears and starts down the surface of the wall of the shelter at different times of the morning depending on the time of the year. The spot grows in size from its first appearance until its maximum size is achieved roughly at midday. It then continues its downward movement until it reaches a point where it jumps to the floor of the shelter. As the Sun continues to move to the west, the spot continues to move across the shelter floor and down the butte, or hill, toward a group of small boulders. If a person is seated on a certain one of these rocks as the spot reaches it, the Sun can be viewed through the calendar hole. This occurs at different times in the afternoon depending on the time of year.托福阅读题目:1.

托福阅读真题1It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time — a mass extinction. One of the best-known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago, when approximately 95 percent of all species died,mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. This periodic extinction might be due to intersection of the Earths orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random events.1. The word it in line 3 refers to(A) environment(B) species(C) extinction(D) 99 percent2. The word ultimately in line 8 is closest in meaning to(A) exceptionally(B) dramatically(C) eventually(D) unfortunately3. What does the author say in paragraph 1 regarding most species in Earths history(A) They have remained basically unchanged from their original forms.(B) They have been able to adapt to ecological changes.(C) They have caused rapid change in the environment.(D) They are no longer in existence.4. Which of the following is NOT mentioned in paragraph 1 as resulting from rapid ecologicalchange?(A) Temperature changes(B) Availability of food resources(C) Introduction of new species(D) Competition among species5. The word demise in line 12 is closest in meaning to(A) change(B) recovery(C) help(D) death6. Why is plankton mentioned in line 17?(A) To demonstrate the interdependence of different species.(B) To emphasize the importance of food resources in preventing mass extinction.(C) To illustrate a comparison between organisms that live on the land and those that live in theocean.(D) To point out that certain species could never become extinct.7. According to paragraph 2, evidence from fossils suggests that(A) Extinction of species has occurred from time to time throughout Earths history.(B) Extinctions on Earth have generally been massive(C) There has been only one mass extinction in Earths history.(D) Dinosaurs became extinct much earlier than scientists originally believed.8.

Which of the following can be inferred about the theory mentioned in Line 21-23?(A) Many scientists could be expected to disagree with it.(B) Evidence to support the theory has recently been found.(C) The theory is no longer seriously considered.(D) Most scientists believe the theory to be accurate.10. In paragraph 3, the author makes which of the following statements about a species survival?(A) It reflects the interrelationship of many species.(B) It may depend on chance events.(C) It does not vary greatly from species to species(D) It is associated with astronomical conditions.11. According to the passage , it is believed that the largest extinction of a species occurred(A) 26 million years ago(B) 65 million years ago(C) 225 million years ago(D) 250 million years agoPASSAGE 77 BCDCD AADAB C托福阅读真题2Archaeological discoveries have led some scholars to believe that the first Mesopotamian inventors of writing may have been a people the later Babylonians called Subarians. According to tradition, they came from the north and moved into Uruk in the south. By about 3100 B.C.,they were apparently subjugated in southern Mesopotamia by the Sumerians, whose name became synonymous with the region immediately north of the Persian Gulf, in the fertile lower valleys of the Tigris and Euphrates. Here the Sumerians were already well established by the year 3000 B.C. They had invented bronze, an alloy that could be cast in molds, out of which they made tools and weapons. They lived in cities, and they had begun to acquire and use capital. Perhaps most important, the Sumerians adapted writing (probably from the Subarians) into a flexible tool of communication.Archaeologists have known about the Sumerians for over 150 years. Archaeologists working at Nineveh in northern Mesopotamia in the mid-nineteenth century found many inscribed clay tablets. Some they could decipher because the language was a Semitic one (Akkadian), on which scholars had already been working for a generation. But other tablets were inscribed in another language that was not Semitic and previously unknown. Because these inscriptions made reference to the king of Sumer and Akkad, a scholar suggested that the new language be called Sumerian.But it was not until the 1890s that archaeologists excavating in city-states well to the south of Nineveh found many thousands of tablets inscribed in Sumerian only. Because the Akkadians thought of Sumerian as a classical language (as ancient Greek and Latin are considered today),they taught it to educated persons and they inscribed vocabulary, translation exercises, and other study aids on tablets. Working from known Akkadian to previously unknown Sumerian, scholars since the 1890s have learned how to read the Sumerian language moderately well. Vast quantities of tablets in Sumerian have been unearthed during the intervening years from numerous sites.1. According to the passage , the inventors of written language in Mesopotamia were probablythe(A) Babylonians(B) Subarians(C) Akkadians(D) Sumerians2. The word subjugated in line 4 is closest in meaning to(A) distinguished(B) segregated(C) concentrated(D) conquered3. The phrase synonymous with in line 5 is closest in meaning to(A) equivalent to(B) important for(C) respected in(D) familiar with4. According to the passage , by the year 3000 B.C. the Sumerians had already done all of thefollowing EXCEPT:(A) They had abandoned the area north of the Persian Gulf.(B) They had established themselves in cities.(C) They had started to communicate through(D) They had created bronze tools and weapons.5. The word some in line 14 refers to(A) Archaeologists(B) Sumerians(C) years(D) clay tablets6. Which of the following can be inferred from the passage concerning the Sumerians?(A) They were descendants of the Persians.(B) They were the first people to cultivate the valley of the Tigris.(C) They were accomplished musicians.(D) They had the beginnings of an economy.7. According to the passage , when did archaeologists begin to be able to understand tabletsinscribed in Sumerian?(A) in the early nineteenth century(B) more than 150 years ago(C) after the 1890s(D) in the mid-eighteenth century8. According to the passage , in what way did the Sumerian language resemble ancient Greek andLatin?(A) It was invented in Mesopotamia.(B) It became well established around 3000 B.C.(C) It became a classical language.(D) It was used exclusively for business transactions.9. The word excavating in line 19 is closest in meaning to(A) living(B) digging(C) assembling(D) building10. According to the passage , how did archaeologists learn to read the Sumerian language?(A) by translating the work of the Subarians(B) by using their knowledge of spoken Semitic languages(C) by comparing Sumerian to other classical languages(D) by using their knowledge of AkkadianPASSAGE 78 BDAAD DCCBD托福阅读真题3Some animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordinate activities within a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious processing.Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered. One example of such unexplained behavior: honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the suns position in the sky, and the speed of the dance tells how far the food source is from the hive. Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site, foraging honeybees began to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of anounce, could have inferred the location of the new site.Other behaviors that may indicate some cognition include tool use. Many animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools. One researcher has found that mother chimpanzees occasionally show their young how to use tools to open hard nuts. In one study, chimpanzees compared two pairs of food wells containing chocolate chips. One pair might contain, say, five chips and three chips, the other four chips and three chips. Allowed to choose which pair they wanted, the chimpanzees almost always chose the one with the higher total, showing some sort of summing ability. Other chimpanzees have learned to use numerals to label quantities of items and do simple sums.1. What does the passage mainly discuss?(A) The role of instinct in animal behavior(B) Observations that suggest consciousness in animal behavior(C) The use of food in studies of animal behavior(D) Differences between the behavior of animals in their natural environments and in laboratoryexperiments.2. Which of the following is NOT discussed as an ability animals are thought to have?(A) Selecting among choices(B) Anticipating events to come(C) Remembering past experiences(D) Communicating emotions3. What is the purpose of the honeybee dance?(A) To determine the quantity of food at a site(B) To communicate the location of food(C) To increase the speed of travel to food sources(D) To identify the type of nectar that is available4. The word yet in line 15 is closest in meaning to(A) however(B) since(C) generally(D) so far5. What did researchers discover in the study of honeybees discussed in paragraph 2?(A) Bees are able to travel at greater speeds than scientists thought.(B) The bees could travel 25% farther than scientists expected.(C) The bees were able to determine in advance where scientists would place their food.(D) Changing the location of food caused bees to decrease their dance activity.6. It can be inferred from the passage that brain size is assumed to(A) be an indicator of cognitive ability(B) vary among individuals within a species(C) be related to food consumption(D) correspond to levels of activity7. Why are otters and mussel shells included in the discussion in paragraph 3?(A) To provide an example of tool use among animals(B) To prove that certain species demonstrate greater ability in tool use than other species(C) To illustrate how otters are using objects as tools(D) To demonstrate why mother chimpanzees show their young how to use tools8. The word rudimentary in line 20 is closest in meaning to(A) superior(B) original(C) basic(D) technical9. It can be inferred from the statement about mother chimpanzees and their young (lines 20-22)that young chimpanzees have difficulty(A) communicating with their mothers(B) adding quantities(C) making choices(D) opening hard nuts10. The phrase the one in line 24-25 refers to the(A) study(B) pair(C) chimpanzee(D) ability11.

7.1托福写作话题解析及高分范文
7月1日托福写作话题解析及高分范文!先奉上7月1日托福独立写作真题~~Do you agree or disagree with the following statement?Competition between friends usually negatively impacts friendships. Use specific details and examples to support your opinion.朋友类朋友类!这是我们预测里面的话题类别,所以吧,我们的预测有参考性吧~~看这里,这是我们北美考试帮对7月1日考试的预测截图:上次说过不仅给预测,而且还给解析甚至范文,马上实现自己的诺言哈,今天解析和范文就来啦~~呜啦呜啦呜啦~~(掌声在哪里~~嘿嘿)解析:就体裁而言是同意不同意(准没准?准没准?);就话题而言是朋友类。
不过这个朋友类呢,有点难度,是说朋友之间的竞争是否影响友谊。
竞争这个话题本身就不太好写,何况还牵涉到朋友之间的竞争,所以就更不好写了。
大家可以想自己思考思考,你是同意呢还是不同意呢?如果同意,你的理由是什么?如果不同意,你的理由又是什么?可以从朋友的范畴上去思考,什么是朋友?诚实,互相帮助...那竞争如何去破坏友谊的哪些呢?所以这里就可以用分类的方法去构思了。
我同意,竞争损害了朋友之间的诚实和互相帮助,而且更严重的是竞争会让朋友互相诋毁。
所以这篇文章的构思就有了。
废话不多说,直接上范文(刚写的,新鲜出炉~~我似乎看了热气~~哈哈)范文:From ancient time to modern days, friendship has played a key role in our daily life. However, it is unavoidable for friends to compete for a stuff in such an increasing interactive and connecting world, such as for a school or for a job. As far as I am concerned, honestly, competition does have a negative influence on friendships among involvers, which will be illustrated in three aspects.To begin with, competition will teach friends to conceal something from each other. Owing to the fact that nearly all of them desire to achieve the goal, competitors will lie to others more or less to lower others’vigilance or to confuse rivals. To be more specific,in the process of preparing for a test, test takers , who are friends and competitors, will not tell opponents which material is significant and which stage they are in; in the pursuit of an advanced position, opponents, to a large extent, will engage in something under the rose, such as treating the boss or bribing voters. A good case in this point is that before taking collegeentrance examination, one of my friends always did not tell me the books she had read and learned. Due to competition, friends are not honest any more like before.In addition, lending friends’a hand cannot be expected in competition. As an old saying said, a friend in need is a friend petition, however, will hinder companion do others a favor on the ground that helping friends is to set obstacles or increase difficulties for themselves. That is to say, it is more hazardous for them to reach the target. Plenty of evidence in our life has proved it. Two boys chasing the same girl definitely do not give advice to each other; two competitive tenders will drive the price higher rather than lower for auction goods; two actresses for a role are unlikely to help the other illustrate the feelings of the role. In short, competition makes friends hesitate to assist each other.What was worse, some opponents even do some harmful things to defame friends. These behaviors include publicizing friends’physical disadvantages, previous relationship and family condition and criticizing friends’dressing style, economic condition and eating habits. To illustrate,in order to win the position of president, Obama’s group claimed Hillary was too old and uglified her photos. Without any doubt, these behaviors break the friendship to some extent.From what have been discussed above, I am extremely convinced that competition between friends will damage friendship and even make them to become enemy not only because competition gives birth to lies, but also friends are unlikely to aid each other as well as it is possible for them to implement some defaming behaviors.看了范文,可以再好好复习里面的词语和句型表达。

托福阅读真题1Cities develop as a result of functions that they can perform. Some functions result directly from the ingenuity of the citizenry, but most functions result from the needs of the local area and of the surrounding hinterland (the region that supplies goods to the city and to which the city furnishes services and other goods). Geographers often make a distinction between the situation and the site of a city. Situation refers to the general position in relation to the surrounding region, whereas site involves physical characteristics of the specific location. Situation is normally much more important to the continuing prosperity of a city. If a city is well situated in regard to its hinterland, its development is much more likely to continue. Chicago, for example, possesses an almost unparalleled situation: it is located at the southern end of a huge lake that forces east-west transportation lines to be compressed into its vicinity, and at a meeting of significant land and water transport routes. It also overlooks what is one of the worlds finest large farming regions. These factors ensured that Chicago would become a great city regardless of the disadvantageous characteristics of the available site, such as being prone to flooding during thunderstorm activity.Similarly, it can be argued that much of New York Citys importance stems from its early and continuing advantage of situation. Philadelphia and Boston both originated at about the same time as New York and shared New Yorks location at the western end of one of the worlds most important oceanic trade routes, but only New York possesses aneasy-access functional connection (the Hudson-Mohawk lowland) to the vast Midwestern hinterland. This account does not alone explain New Yorks primacy, but it does include several important factors. Among the many aspects of situation that help to explain why some cities grow and others do not, original location on a navigable waterway seems particularly applicable. Of course, such characteristic as slope, drainage, power resources, river crossings, coastal shapes, and other physical characteristics help to determine city location, but such factors are normally more significant in early stages of city development than later.1. What does the passage mainly discuss?(A) The development of trade routes through United States cities(B) Contrasts in settlement patterns in United States(C) Historical differences among three large United States cities(D) The importance of geographical situation in the growth of United States cities2.

The philosophy of the movement combined realism, ethnic consciousness, and Americanism. Encouraged by the example of certain Americans ofEuropean descent such as Thomas Eakins, Robert Henri, and George Luks, who had included persons of African descent in their paintings as serious studies rather than as trivial or sentimental stereotypes, African American artists of this period set about creating a new portrayal of themselves and their lives in the United States. As they began to strive for social and cultural independence. Their attitudes toward themselves changed, and, to some extent, other segments of American society began to change their attitudes toward them. Thus, though the Harlem Renaissance was a short-lived movement, its impact on American art and culture continues to the present.The district in New York City known as Harlem was the capital of the movement. In 1925 an issue of Survey Graphic magazine devoted exclusively to Harlem and edited by philosopher Alain Locke became the manifesto of the African American artistic movement. Locke strongly suggested that individuals, while accepting their Americanism, take pride in their African ancestral arts and urged artists to look to Africa for substance and inspiration. Far from advocating a withdrawal from American culture, as did some of his contemporaries, Locke recommended a cultural pluralism through which artists could enrich the culture of America. African Americans were urged by Locke to be collaborators and participators with other Americans in art, literature, and music; and at the same time to preserve, enhance, and promote their own cultural heritage.Artists and intellectuals from many parts of the United States and the Caribbean had been attracted to Harlem by the pulse and beat of its unique and dynamic culture. From this unity created by the convergence of artists from various social and geographical backgrounds came a new spirit, which, particularly in densely populated Harlem, was to result in greater group awareness and self-determination. African American graphic artists took their place beside the poets and writers of the Harlem Renaissance and carried on efforts to increase and promote the visual arts.1. What does the passage mainly discuss?(A) African American paintings in the 1920s(B) An arts movement of the 1920s(C) The influence of Alain Locke on African American art(D) Some ways in which African culture inspired American literature, art and music2. According to the passage , Tomas Eakins, Robert Henri, and George Luks were important because of(A) the philosophical contributions they made to the Harlem Renaissance(B) their development of a new style of African American art(C) they way in which they depicted African Americans in their paintings(D) their independence from European artistic traditions3. The word them in line 11 refers to(A) Americans of European descent(B) paintings(C) African American artists(D) attitudes4. According to the passage , African American artists of the 1920s differed from earlier AfricanAmerican artists in terms of their feelings about(A) themselves(B) other artists(C) their impact on American art(D) stereotypes5. The word urged in line 17 is closest in meaning to(A) prepared(B) defined(C) permitted(D) encouraged6. Alain Locke believed all of the following to be important to the African American artisticmovement EXCEPT(A) pride in African art(B) cultural pluralism(C) collaboration with other artists(D) withdrawal from American culture7. In mentioning the pulse and beat (line 25) of Harlem during the 1920s, the author ischaracterizing the district as one that(A) depended greatly on its interaction with other parts of the city(B) grew economically in a short period of time(C) was an exciting place to be(D) was in danger of losing population8. The word convergence in line 26 is closest in meaning to(A) gathering(B) promotion(C) expression(D) influence9.

Yet historically this widespread faith in the economic virtues of science is a relatively recent phenomenon, dating back in the United States about 150 years, and in the Western world as a whole not over 300 years at most. Even in this current era of large scale, intensive research and development, the interrelationships involved in this process are frequently misunderstood. Until the coming of the Industrial Revolution, science and technology evolved for the most part independently of each other. Then as industrialization became increasingly complicated, the craft techniques of preindustrial society gradually gave way to a technology based on the systematic application of scientific knowledge and scientific methods. This changeover started slowly and progressed unevenly. Until late in the nineteenth century, only a few industries could use scientific techniques or cared about using them. The list expanded noticeably after 1870, but even then much of what passed for the application of science wasengineering science rather than basic science.Nevertheless, by the middle of the nineteenth century, the rapid expansion of scientific knowledge and of public awareness — if not understanding — of it had created a belief that the advance of science would in some unspecified manner automatically generate economic benefits. The widespread and usually uncritical acceptance of this thesis led in turn to the assumption that the application of science to industrial purposes was a linear process, starting with fundamental science, then proceeding to applied science or technology, and through them to industrial use. This is probably the most common pattern, but it is not invariable. New areas of science have been opened up and fundamental discoveries made as a result of attempts to solve a specific technical or economic problem. Conversely, scientists who mainly do basic research also serve as consultants on projects that apply research in practical ways.In sum, the science-technology-industry relationship may flow in several different ways, and the particular channel it will follow depends on the individual situation. It may at times even be multidirectional.1. What is the authors main purpose in the passage ?(A) To show how technology influenced basic science(B) To describe the scientific base of nineteenth-century American industries(C) To correct misunderstandings about the connections between science, technology, and industry(D) To argue that basic science has no practical application2. The word altogether in line 2 is closest in meaning to(A) completely(B) realistically(C) individually(D) understandably3. The word intensive in line 5 is closest in meaning to(A) decreased(B) concentrated(C) creative(D) advanced4. The list mentioned in line 13 refers to(A) types of scientific knowledge(B) changes brought by technology(C) industries that used scientific techniques(D) applications of engineering science5. The understanding of research and development in the late nineteenth century is based onwhich of the following?(A) Engineering science is not very important.(B) Fundamental science naturally leads to economic benefits.(C) The relationship between research and development should be criticized.(D) Industrial needs should determine what areas fundamental science focuses on.6. The word it in line 16 refers to(A) understanding(B) public awareness(C) scientific knowledge(D) expansion7. The word assumption in line 19 is closest in meaning to(A) regulation(B) belief(C) contract(D) confusion8. Why does the author mention consultants in line 25?(A) To show how new areas of science have given rise to new professions(B) To distinguish between scientists who work in industry and those who do not(C) To explain the ways in which scientists find financial support for their work(D) To show how scientists who work in basic research contribute to applied science9. Which of the following statements does the passage support?(A) The development of science and of industry is now interdependent.(B) Basic scientific research cannot generate practical applications.(C) Industries should spend less money on research and development.(D) Science and technology are becoming more separate.PASSAGE 73 CABCB CBDA托福阅读真题4Glaciers are large masses of ice on land that show evidence of past or present movement. They grow by the gradual transformation of snow into glacier ice.A fresh snowfall is a fluffy mass of loosely packed snowflakes, small delicate ice crystals grown in the atmosphere. As the snow ages on the ground for weeks or months, the crystals shrink and become more compact, and the whole mass becomes squeezed together into a more dense form, granular snow. As new snow falls and buries the older snow,the layers of granular snow further compact to form firm, a much denser kind of snow, usually a year or more old, which has little pore space. Further burial and slow cementation — a process by which crystals become bound together in a mosaic of intergrown ice crystals — finally produce solid glacial ice. In this process of recrystallization, the growth of new crystals at the expense of old ones, the percentage of air is reduced from about 90 percent for snowflakes to less than 20 percent for glacier ice. The whole process may take as little as a few years, but more likely ten or twenty years or longer. The snow is usually many meters deep by the time the lower layers are converted into ice.In cold glaciers those formed in the coldest regions of the Earth, the entire mass of ice is at temperatures below the melting point and no free water exists. In temperate glaciers, the ice is at the melting point at every pressure level within the glacier, and free water is present as small drops or as larger accumulations in tunnels within or beneath the ice.Formation of a glacier is complete when ice has accumulated to a thickness (and thus weight) sufficient to make it move slowly under pressure, in much the same way that solid rock deep within the Earth can change shape without breaking. Once that point is reached, the ice flows downhill, either as a tongue of ice filling a valley or as thick ice cap that flows out in directions from the highest central area where the most snow accumulates. The trip down leads to the eventual melting of ice.1. Which of the following does the passage mainly discuss?(A) The effect of glaciers on climate(B) Damage from glaciers(C) Glacier formation(D) The location of glaciers2. Which of the following will cause density within the glacier to increase?(A) Increased water and air content(B) Pressure from the weight of new snow(C) Long periods of darkness and temperature variations(D) Movement of the glacier3. The word bound in line 9 is closest in meaning to(A) covered(B) chosen(C) planned(D) held4. Which of the following will be lost is a glacier forms?(A) Air(B) Pressure(C) Weight(D) Rocks5. According to the passage , which of the following is the LEAST amount of time necessary forglacial ice to form?(A) several months(B) several years(C) at least fifty years(D) a century6. The word converted in line 15 is closest in meaning to(A) changed(B) delayed(C) promoted(D) dissolved7. What is the purpose of the material in paragraph three?(A) To define two types of glaciers(B) To contrast glacier ice with non-glacier ice(C) To present theories of glacier formation(D) To discuss the similarities between glacial types8.

0308托福试题阅读(55minutes)Question 1-11If food is allowed to stand for some time, it putrefies .When the putrefied materialis examined microscopically ,it is found to be teeming with bacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 )generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10)this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety of solid structures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembled the reproductive (15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated that these bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary for spontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer support spontaneous generation.

In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) nor alkaline(higher insalt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically alkaline and must be fertilized back toward neutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10) water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as onecrosses the(25) border into the Northeast United States. As one proceeds toward the Southeast,broadleaf vegetation becomes dominant. Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A) The wide variety of climates(B) Soil types and vegetation patterns(C) Improved irrigation methods and the expansion of agriculture(D) The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A) distinguish(B) eliminate(C) protect(D) create23 The word “partitioning” in line 2 is closest in meaning to(A) division(B) modification(C) opening(D) circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B) an increase in farming(C) large amounts of rain(D) glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A) implied(B) increased(C) indicated(D) informed26 How did glacial meltdown affect the soil in North America?(A) It redistributed the soil types(B) It added salt to the soil(C) It made the soil more neutral in content(D) It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A) movements of glacial deposits(B) patterns of natural vegetation(C) human modification of the North American environment(D) distinction between humid America and arid America28 Th e word “transition” in line 23 is closest in meaning to(A) elevation(B) change(C) advantage(D) condition29 The passage supports which of the following statements?(A) Arid America is not necessarily characterized by the presence of deserts(B) Most of Canada and the northeastern United States consists of short-grassprairies wherever natural vegetation has not been modified by humans(C) The accumulation of loess is primarily the result of irrigation(D) Glaciation removed the fertile layer of soil from much of the Mississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting. Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the earliest type, the metal(15) was separated from the oxygen by a thin glass bulb. The flash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignited spontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emission of visible light. Thesmoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A) The history of the photoflash(B) Theories about how the eye reacts to light(C) The technology of modern photography(D) The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A) recording of an image on film(B) generation of artificial light(C) creation of a photographic emulsion(D) human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A) can produce repeated bursts of light(B) intensities colors in photographs(C) is short enough not to bother human eyes(D) supplements existing lighting33 The word “ignited” in line 9 is closest in meaning to(A) set on fire(B) cut into(C) opened(D) shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(line 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A) publicity(B) adoption(C) development(D) manufacture36 The function of the glass in the first flashbulbs was to(A) produce the spark that initiated the flash(B) magnify the light produced by the flash(C) protect the photographer from the heat of the flash(D) keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A) oxygen(B) battery(C) wire(D) current38 The word “momentarily” in line 20 is closest in meaning to(A) effortlessly(B) briefly(C) electronically(D) gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A) rapid cooling(B) bright illumination(C) electrical conductivity(D) intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A) thicker wire(B) more oxygen(C) thinner glass(D) continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s.The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solidsurfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewed through hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25)From then until 1886 Impressionism had all the zeal of a “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A) The impact of some artists’ resistance to the fast pace of life(B) The differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in meaning to(A) reorganize(B) deform(C) represent(D) justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A) The emphasis on people rather than nature scenes(B) The way the subjects were presented from multiple angles(C) The focus on small solid objects(D) The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A) They began by making sketches of their subjects(B) They painted their subjects out-of-doors(C) They preferred to paint from memory(D) They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A) achievement(B) acceptance(C) arrival(D) advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A) attracting attention from the public(B) a negative reaction from the press(C) an immediate demand for the paintings exhibited(D) creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A) insult(B) encouragement(C) return(D) credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A) The small number of paintings on display(B) Lack of interest in exhibitions by young artists(C) The similarity between all the paintings exhibited(D) Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A) became as famous as Monet(B) was consistently praised by art critics(C) described the enthusiasm of the Impressionists for their work(D) was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A) art critics(B) fellow artists(C) individual differences(D) new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABA CACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

托福阅读真题第7篇Regulation_of_Body_Temperature(答案文章最后)
托福阅读真题第7篇Regulation_of_Body_Temperature(答案文章最后)Regulation of ody TemperatureMost animals have an upper limit of body temperature at which they can survive.In humans, for example, a body temperature of 41 degrees elsius causes loss of protein function and breakdown of the nervous system, and a body temperature of 42 to 43 degrees elsius is fatal. irds, which have slightly higher resting body temperatures than mammals(approximately 40 to 41 degrees elsius compared with 35 to 38 degrees elsius for most mammals), cannot survive at body temperatures above 46 to 47 degrees elsius. t environmental temperatures greater than 50 degrees elsius, nearly all animals die. t the other end of the temperature spectrum, though, extreme cold is better tolerated. Fo example, Some animals can freeze and survive after thawing. Freezing/thawing is normally dangerous because ice crystals form inside cells and rupture membranes. However, many insects, such as the woolly caterpillar, a few species of amphibian such as the wood frog, and a very small number of reptiles such as the painted turtle, can block crystal formation in their cells. They do this by responding to ice on their skin surfaces with an enormous outpouring of glucose from the liver. The glucose stored in the liver enters the blood and the cells, lowering their freezing point so that the cells do not freeze solid. These animals can have 65 percent or more of their bodies completely frozen for long periods, only to thaw during warm periods without harmful effects.In the past, animals were classified into two categories. old blooded animals require an external heat source such as sunlightto warm themselves. y contrast, warm-blooded animals use internal heat to maintain their body temperature. These terms are misleading, however, because many cold-blooded animals can generate considerable heat by exercising their skeletal muscles. Indeed, many have a body temperature during daylight hours that is at least as warm as that of warm blooded animals like birds and mammals.iologists now classify animals according to both their source of heat and their ability to maintain body temperature. Ectotherms depend on external heat sources to warm their bodies, while endotherms use their own metabolically generated heat to warm themselves. Homeotherms maintain their body temperature within a narrow range, while heterotherrms have body temperatures that vary with the environment. Most animals fall into two categories. irds and mammals are endothermic and homeothermic. while other vertebrates and most invertebrates are ectothermic and heterothermic.Not all animals, however, can be neatly classified into two categories at all times.Hibernating mammals, for example, are endotherms. They are homeothermic, but during the winter their body temperature drops dramatically as their metabolism slows to conserve energy for the winter. Hibernators behave like heterotherms during the transition from fall to winter and again from winter to spring, uring the winter, however, they are homeothermic except for brief periods of arousal, but at a lower body temperature than at other times of the year. Similarly, a fish swimming in deep ocean waters is an ectotherm but also homeothermic because the temperature of the water-and therefore of its body-is essentially constant. Fish that live in waters with fluctuating temperatures, by contrast areectothermic and heterothermic.Even endothermic homeotherms do not have truly constant body temperatures but rather a narrow range of body temperatures within which slight increases and decreases occur in extreme climates during exercise, or even during sleep. The important feature is that birds and mammals can quickly adjust the body's mechanisms for retaining or releasing heat such that body temperature remains relatively stable. This provides the advantage that the body chemical reactions are at optimal levels even when the environment imposes extreme challenges. The metabolic rate of a resting mammal, for example, is roughly six times greater than that of a comparably sized reptile. suddenly awakened mammal is capable of intense activity even on a winter day, but an icy-cold reptile could be at the mercy of a predator because of the time required to warm itself and flee.Endothermy does have two major disadvantages, however. First, to produce sufficient heat by metabolic processes, endotherms must consume larger amounts of food. Small endotherms, such as shrews, must eat almost continually and may die if deprived of food for as little as a day. y contrast, many ectotherms, such as snakes can go for weeks without eating. Second, endotherms run the risk of overheating during periods of intense activity, even in cold weather.1.Most animals have an upper limit of body temperature at which they can survive.In humans, for example, a body temperature of 41 degrees elsius causes loss of protein function and breakdown of the nervous system, and a body temperature of 42 to 43 degrees elsius is fatal. irds, which have slightly higher resting body temperatures than mammals(approximately 40 to 41 degrees elsius compared with 35 to 38 degrees elsius for mostmammals), cannot survive at body temperatures above 46 to 47 degrees elsius. t environmental temperatures greater than 50 degrees elsius, nearly all animals die. t the other end of the temperature spectrum, though, extreme cold is better tolerated.

历年托福考试阅读真题汇总(附答案)
0308托福试题阅读(55minutes)Question 1-11If food is allowed to stand for some time, it putrefies .When the putrefied materialis examined microscopically ,it is found to be teeming with bacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 )generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10) this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety of solid structures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembledthe reproductive(15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated thatthese bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer support spontaneousgeneration. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck prevented microorganisms from getting in the flask.. Material sterilized in such a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’s argument against the theory of spontaneous generation . 2,The phrase “teeming with ”in line 2 is closest in meaning to(a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word “resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the “guncotton” mentioned in paragraph 2 was to(a)trap particles for analysis(b)slow the process of putrefaction(c)increase the airflow to the microscopic slide(d)aid the mixing of alcohol and ether6,The author mention “1.0mm”in line 14 in describing the(a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “postulated”in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experiment were remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefying materials(c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word “it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important for the process to succeed ?(a)A sealed container(b)Fresh air(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in future experiments(b)prevent heat from building up in a solution(c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of airQuestions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society’s hero. In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agriculturalFor their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded(25)less to the expectations of agrarians and governmentinducements than to growing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directly related to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “depended” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to the creation of a good society(d)a farmer who guided the agrarian movement toward an emphasis on economic development15.The phrase “subscribed to” in line 8 is closest in meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’s views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agriculture was a vital part of the nation’s economy.17.According to the passage , the national and state governments did all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers’ meeting the expectations of agrarian philosophers EXCEPT(a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word “stunning” in line 24 is closest in meaning to(a)predictable(b)impressive(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States.(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) noralkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10)water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation me thods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the(25)border into the Northeast United States. As one proceedstoward the Southeast, broadleaf vegetation becomes dominant.Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A) The wide variety of climates(B) S oil types and vegetation patterns(C) I mproved irrigation methods and the expansion of agriculture(D) The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A) distinguish(B) e liminate(C) p rotect(D) create23 The word “partitioning” in line 2 is closest in meaning to(A) division(B) m odification(C) o pening(D) circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B) a n increase in farming(C) l arge amounts of rain(D) glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A) implied(B) i ncreased(C) i ndicated(D) informed26 How did glacial meltdown affect the soil in North America?(A) It redistributed the soil types(B) I t added salt to the soil(C) I t made the soil more neutral in content(D) It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A) movements of glacial deposits(B) p atterns of natural vegetation(C) h uman modification of the North American environment(D) distinction between humid America and arid America28 The word “transition” in line 23 is closest in meaning to(A) elevation(B) c hange(C) a dvantage(D) condition29 The passage supports which of the following statements?(A) Arid America is not necessarily characterized by the presenceof deserts(B) M ost of Canada and the northeastern United States consists ofshort-grass prairies wherever natural vegetation has not been modified by humans(C) T he accumulation of loess is primarily the result of irrigation(D) Glaciation removed the fertile layer of soil from much of theMississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting.Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the earliest type, the metal (15) was separated from the oxygen by a thin glass bulb. The flash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emissionof visible light. The smoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A) The history of the photoflash(B) T heories about how the eye reacts to light(C) T he technology of modern photography(D) The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A) recording of an image on film(B) g eneration of artificial light(C) c reation of a photographic emulsion(D) human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A) can produce repeated bursts of light(B) i ntensities colors in photographs(C) i s short enough not to bother human eyes(D) supplements existing lighting33 The word “ignited” in line 9 is closest in meaning to(A) set on fire(B) c ut into(C) o pened(D) shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed mov ement”(line 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A) publicity(B) a doption(C) d evelopment(D) manufacture36 The function of the glass in the first flashbulbs was to(A) produce the spark that initiated the flash(B) m agnify the light produced by the flash(C) p rotect the photographer from the heat of the flash(D) keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A) oxygen(B) b attery(C) w ire(D) current38 The word “momentarily” in line 20 is closest in meaning to(A) effortlessly(B) b riefly(C) e lectronically(D) gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A) rapid cooling(B) b right illumination(C) e lectrical conductivity(D) intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A) thicker wire(B) m ore oxygen(C) t hinner glass(D) continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewedthrough hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25)From then until 1886 Impressionism had all the zeal of a “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A) The impact of some artists’ resistance to the fast pace of life(B) T he differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in meaning to(A) reorganize(B) d eform(C) r epresent(D) justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A) The emphasis on people rather than nature scenes(B) T he way the subjects were presented from multiple angles(C) T he focus on small solid objects(D) The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A) They began by making sketches of their subjects(B) T hey painted their subjects out-of-doors(C) T hey preferred to paint from memory(D) They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A) achievement(B) a cceptance(C) a rrival(D) advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A) attracting attention from the public(B) a negative reaction from the press(C) a n immediate demand for the paintings exhibited(D) creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A) insult(B) e ncouragement(C) r eturn(D) credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A) The small number of paintings on display(B) L ack of interest in exhibitions by young artists(C) T he similarity between all the paintings exhibited(D) Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A) became as famous as Monet(B) w as consistently praised by art critics(C) d escribed the enthusiasm of the Impressionists for their work(D) was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A) art critics(B) f ellow artists(C) i ndividual differences(D) new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABACACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

【王鑫托福阅读】托福TPO7-1阅读文本TPO7TPO7-1 The Geologic History of the MediterraneanAnother task for the Glomar Challenger's scientists was to try to determine the origin of the domelike masses buried deep beneath the Mediterranean seafloor. These structures had been detected years earlier by echo-sounding instruments, but they had never been penetrated in the course of drilling.Were they salt domes such as are common along the United States Gulf Coast, and if so, why should there have been so much solid crystalline salt beneath the floor of the Mediterranean?1. The word “objective” i n the passage is closest in meaning toA. achievementB. requirementC. purposeD. feature2. Which of the following is NOT mentioned in paragraph 1 as a change that occurred in the fauna of the Mediterranean?A. Most invertebrate species disappeared during a wave of extinctions.B. A few hardy species wiped out many of the Mediterranean’ s invertebrates.C. Some invertebrates migrated to Atlantic Ocean.D. New species of fauna populated the Mediterranean when the old migrants returned.In 1970 geologists Kenneth J. Hsu and William B.F. Ryan were collecting research data while aboard the oceanographic research vessel Glomar Challenger. An objective of this particular cruise was to investigate the floor of the Mediterranean and to resolve questions about its geologic history. One question was related to evidence that the invertebrate fauna (animals without spines) of the Mediterranean had changed abruptly about 6 million years ago. Most of the older organisms were nearly wiped out, although a few hardy species survived. A few managed to migrate into the Atlantic. Somewhat later, the migrants returned, bringing new species with them. Why did the near extinction and migrations occur?3. What does the author imply by saying “Not a single pebb le was found that might have indicated that the pebbles came from the nearby continent” ?A. The most obvious explanation for the origin of the pebbles was not supported by the evidence.B. The geologists did not find as many pebbles as they expected.C. The geologists were looking for a particular kind of pebble.D. The different pebbles could not have come from only one source.4. Which of the following can be inferred from paragraph 3 about the solid gypsum layer?A. It did not contain any marine fossil.B. It had formed in open-ocean conditions.C. It had once been soft, deep-sea mud.D. It contained sediment from nearby deserts.ve credit you5.Select the TWO answer choice from paragraph 3 that identify materials discovered in the deepest part of the Mediterranean basin. To receive credit must select TWO answers.A. Volcanic rock fragments.B. Thin silt layersC. Soft, deep-sea mudD. Crystalline saltWith question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered a sample. The sample consisted of pebbles of hardened sediment that had once been soft, deep-sea mud, as well as granules of gypsum and fragments of volcanic rock. Not a single pebble was found that might have indicated that the pebbles came from the nearby continent. In the days following, samples of solid gypsum were repeatedly brought on deck as drilling operations penetrated the seafloor. Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats. Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions. As they drilled into the central and deepest part of the Mediterranean basin, the scientists took solid, shiny, crystalline salt from the core barrel. Interbedded with the salt were thin layers of what appeared to be windblown silt.1. What is the main purpose of paragraph 3?A. To describe the physical evidence collected by Hsu and RyanB. To explain why some of the questions posed earlier in the passage could not be answered by the findings of the Glomar ChallengerC. To evaluate techniques used by Hsu and Ryan to explore the sea floorD. To describe the most difficult problems faced by the Glomar Challenger expedition2. According to paragraph 4, which of the following was responsible for the evaporation of the Mediterranean ’ s waters?A. The movements of Earth’ s crustB. The accumulation of sediment layersC. Changes in the water level of the Atlantic OceanD. Changes in Earth’ s temperature3. The word “scores” in the passage is closest in meaning toA. membersB. large numbersC. populationsD. different types4. According to paragraph 4, what caused most invertebrate species in the Mediterranean to become extinct?A .The evaporation of chemicals necessary for their survivalA. Crustal movements that connected the Mediterranean to the saltier AtlanticB. The migration of new species through the narrow straitsC. Their inability to tolerate the increasing salt content of the MediterraneanThe time had come to formulate a hypothesis. The investigators theorized that about 20 million years ago, the Mediterranean was a broad seaway linked to the Atlantic by two narrow straits. Crustal movements closed the straits, and the landlocked Mediterranean began to evaporate. Increasing salinity caused by the evaporation resulted in the extermination of scores of invertebrate species. Only a few organisms especially tolerant of very salty conditions remained. As evaporation continued, the remaining brine (salt water) became so dense that the calcium sulfate of the hard layer was precipitated. In the central deeper part of the basin, the last of the brine evaporated to precipitate more soluble sodium chloride (salt). Later, under the weight of overlying sediments, this salt flowed plastically upward to form salt domes.Before this happened, however, the Mediterranean was a vast desert 3,000 meters deep. Then, about 5.5 million years ago came the deluge. As a result of crustal adjustments and faulting, the Strait of Gibraltar, where the Mediterranean now connects to the Atlantic, opened, and water cascaded spectacularly back into the Mediterranean. Turbulent waters tore into the hardened salt flats, broke them up, and ground them into the pebbles observed in the first sample taken by the Challenger. As the basin was refilled, normal marine organisms returned. Soon layer of oceanic ooze began to accumulate above the old hard layer.V5. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.A. The strait of Gibraltar reopened when the Mediterranean and the Atlantic became connected and the cascades of water from one sea to the other caused crustal adjustments and faulting.B. The Mediterranean was dramatically refilled by water from the Atlantic when crustal adjustments and faulting opened the Strait of Gibraltar, the place where the two seas are joined.C. The cascades of water from the Atlantic to the Mediterranean were not as spectacular as the crustal adjustments and faulting that occurred when the Strait of Gibraltar was connected to those seas.D. As a result of crustal adjustments and faulting and the creation of the Strait of Gibraltar, the Atlantic and Mediterranean were connected and became a single sea with spectacular cascades of water between them.6. The word “Turbulent” in the passage is closest in meaning toA. FreshB. DeepC. ViolentD. TemperateThe salt and gypsum, the fauna丨 changes, and the unusual gravel provided abundant evidence that the Mediterranean was once a desert.gypsum: a mineral made of calcium sulfate and water(Another task for the Glomar Challenger's scientists was to try to determine the origin of the domelike masses buried deep beneath the Mediterranean seafloor. (These structures had been detected years earlier byecho-sounding instruments, but they had never been penetrated such as are common along the United States Gulf Coast, and if crystalline salt beneath the floor of the Mediterranean? ( in the course of drilling.( Were they salt domes so, why should there have been so much solid7. Look at the four squares [■] that indicate where the followi ng sentence could be added to the passage. Where would the sentence best fit?Thus, scientists had information about the shape of the domes but not about their chemical composition and origin.8. Direction: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.

相关背景:Mesoamerica is a region and cultural area in the Americas, extending approximately from central Mexico to Belize, Guatemala, ElSalvador, Honduras, Nicaragua, and northern Costa Rica, within which a number of pre-Columbian societies flourished before theSpanish colonization of the Americas in the 15th and 16th centuries.[1][2]It is one of six areas in the worldwhere ancient civilization arose independently, and the second in the Americas after Norte Chico (Caral-Supe) in present-day northern coastalPeru.As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures. Beginning as early as 7000 BC, the domestication of maize, beans, squash and chili, as well asthe turkey and dog, caused a transition from paleo-Indian hunter-gatherer tribal grouping to the organization of sedentary agricultural villages. In the subsequent formative period, agriculture and cultural traits such as acomplex mythological and religious tradition, a vigesimalnumeric system, anda complex calendric system, a tradition of ball playing, and adistinct architectural style, were diffused through the area. Also in this period, villages began to become socially stratified and develop into chiefdoms with the development of large ceremonial centers, interconnected by a network of trade routes for the exchange of luxury goods, suchas obsidian, jade,cacao, cinnabar, Spondylus shells, hematite, and ceramics. While Mesoamerican civilization did know of the wheel and basic metallurgy, neither of these technologies became culturally important.[3]Among the earliest complex civilizations was the Olmec culture, which inhabited the Gulf coast of Mexico and extended inland and southwards across the Isthmus of Tehuantepec. Frequent contact and cultural interchange between the early Olmec and other cultures in Chiapas, Guatemala and Oaxaca laid the basis for the Mesoamerican cultural area. This formative period saw the spread of distinct religious and symbolic traditions, as well as artistic and architectural complexes. In the subsequent Preclassic period, complex urban polities began to develop amongthe Maya, with the rise of centers such as El Mirador, Calakmul and Tikal, and theZapotec at Monte Albán. During this period, the first true Mesoamerican writing systems were developed in the Epi-Olmec and the Zapotec cultures, and the Mesoamerican writing tradition reached its height in the Classic Maya Hieroglyphic script.Mesoamerica is one of only five regions of the world where writing was independently developed. In Central Mexico, the height of the Classic period saw the ascendancy of the city of Teotihuacan, which formed a military and commercial empire whose political influence stretched south into the Maya area and northward. Upon the collapse of Teotihuacán around AD 600, competition between several important political centers in central Mexico, such as Xochicalco and Cholula, ensued. At this time during the Epi-Classic period, the Nahua peoples began moving south into Mesoamerica from the North, and became politically and culturally dominant in central Mexico, as they displaced speakers of Oto-Manguean languages. During the early post-Classic period, Central Mexico was dominated by the Toltec culture, Oaxaca by the Mixtec, and the lowland Maya area had important centers at Chichén Itzáand Mayapán. Towards the end of the post-Classic period, the Aztecs of Central Mexico built a tributary empire covering most of central Mesoamerica.[4]The distinct Mesoamerican cultural tradition ended with the Spanish conquest in the 16th century. Over the next centuries, Mesoamerican indigenous cultures were gradually subjected to Spanish colonial rule. Aspects of the Mesoamerican cultural heritage still survive among the indigenous peoples who inhabit Mesoamerica, many of whom continue to speak their ancestral languages, and maintain many practices harking back to their Mesoamerican roots.[5]Paleo-Indian[edit]The Mesoamerican Paleo-Indian period precedes the advent of agriculture and is characterized by a nomadic hunting and gathering subsistence strategy. Big-game hunting, similar to that seen in contemporaneous North America, was a large component of the subsistence strategy of the Mesoamerican Paleo-Indian. Evidence for this time period in Mesoamerica is sparse and the documented sites scattered c. 10,500 BC. These include Chi vacabé, Los Tapiales, and Puerta Parada in the highlands of Guatemala, Orange Walkin Belize, and the El Gigante cave in Honduras.[citation needed]These latter sites had a number of obsidian bladesand Clovis-style fluted projectile points. Fishtail points, the most common style in South America, were recovered from Puerta Parada, dated to c. 10,000 BC, as well as other sites including Los Grifos cave in Chiapas (c. 8500 BC)and Iztapan (c. 7700–7300 BC), a mammoth kill site located in the Valley of Mexico near Texcoco.[citation needed]Archaic[edit]The Archaic period (8000–2000 BC) is characterized by the rise of incipient agriculture in Mesoamerica. The initial phases of the Archaic involved the cultivation of wild plants, transitioning into informal domestication and culminating with sedentism and agricultural production by the close of the period. Archaic sites include Sipacate inEscuintla, Guatemala, where maize pollen samples date to c. 3500 BC.[13]The well-known Coxcatlan cave site in the Valley of Tehuacán, Puebla, which contains over 10,000teosinte cobs (an antecedentto maize), and Guilá Naquitz in Oaxaca represent some of the earliest examples of agriculture in Mesoamerica. The early development of pottery, often seen as a sign of sedentism, has been documented at a number of sites, including the West Mexican sites of Matanchén in Nayarit and Puerto Marqués in Guerrero. La Blanca, Ocós, and Ujuxte in the Pacific Lowlands of Guatemala yielded pottery dated to c. 2500 BC.[citation needed]Classic[edit]Early Classic[edit]The Classic period is marked by the rise and dominance of several polities. The traditional distinction between the Early and Late Classic are marked by their changing fortune and their ability to maintain regional primacy. Of paramount importance are Teotihuacán in central Mexico and Tikal in Guatemala; the Early Classic’s temporal limits generally correlate to the main periods of these sites. Monte Alban in Oaxaca is another Classic-period polity that expanded and flourished during this period, but the Zapotec capital exerted less interregional influence than the other two sites.During the Early Classic, Teotihuacan participated in and perhaps dominated afar-reaching macro-regional interaction network. Architectural and artifact styles (talud-tablero, tripod slab-footed ceramic vessels) epitomized at Teotihuacan were mimicked and adopted at many distant settlements. Pachuca obsidian, whose trade and distribution is argued to have been economically controlled by Teotihuacan, is found throughout Mesoamerica.Tikal came to dominate much of the southern Maya lowlands politically, economically, and militarily during the Early Classic. An exchange network centered at Tikal distributed a variety of goods and commodities throughout southeast Mesoamerica, such as obsidian imported from central Mexico (e.g., Pachuca) and highland Guatemala (e.g., El Chayal, which was predominantly used by the Maya during the Early Classic), and jade from the Motagua valley in Guatemala. Carved inscriptions at the site attest to direct interaction with individuals adorned in Teotihuacan-styled dress c. AD 400.[citation needed]However, Tikal was often in conflict with other polities in the Petén Basin, as well as with others outside of it,including Uaxactun, Caracol, Dos Pilas, Naranjo, and Calakmul. Towards the end of the Early Classic, this conflict lead to Tikal’s military defeat at the hands of Caracol in 562, and a period commonly known as the Tikal Hiatus.Late Classic[edit]The Late Classic period (beginning ca. AD 600 until AD 909 [varies]) is characterized as a period of interregional competition and factionalization among the numerous regional polities in the Maya area. This largely resulted from the decrease in Tikal’s socio-political and economic power at the beginning of the period. It was therefore during this time that a number of other sites rose to regional prominence and were able to exert greater interregional influence, includingCaracol, Copán, Palenque, and Calakmul (which was allied with Caracol and may have assisted in the defeat of Tikal), and Dos Pilas Aguateca and Cancuén inthe Petexbatún region of Guatemala. Around 710, Tikal arose again and started to build strong alliances and defeat its worst enemies. In the Maya area, the Late Classic ended with the so-called "Maya collapse", a transitional period coupling the general depopulation of the southern lowlands and development and florescence of centers in the northern lowlands.Some Mesoamerican cultures never achieved dominant status or left impressive archeological remains but should be mentioned as noteworthy. These includethe Otomi, Mixe–Zoque groups (which may or may not have been related to the Olmecs), the northern Uto-aztecan groups, often referred to as the Chichimeca, that include the Cora andHuichol, the Chontales, the Huaves, and the Pipil, Xincan and Lencan peoples of Central America.Summary of the Chronology and Cultures of MesoamericaPeriod Timespan Important cultures, citiesPaleo-In dian 10,000–3500 BCHonduras, Guatemala, Belize, obsidian and pyrite points, Iztapan,Archaic 3500–1800 BCAgricultural settlements,TehuacánPreclass ic (Formati ve) 2000BC–AD250Unknown culture in La Blanca and Ujuxte,Monte Alto cultureEarly Preclass ic 2000–1000 BCOlmec area:San Lorenzo Tenochtitlan; Central Mexico:Chalcatzingo;Valley of Oaxaca:San José Mogote.
