Passage 1

The novelist Robert Herrick was born in Cambridge, Massachusetts, on April 26, 1868. His oldest American ancestor, a nephew of the author of Hesperides, had settled at Salem in 1638; he was related to the Hales, the Mannings, the Hawthornes, and the Peabodys; his immediate forebears were lawyers, teachers, and clergymen. At Harvard, he was a contemporary of Santayana. William Vaughn Moody,Norman Hpgood, and Robert Morss Lovett; he nearly wrecked the Harvard Monthly when he sullied its chaste pages with the first English translation of lbsen's ludy from the Sea. His teaching began at the Massachusetts Institute of Technology, but William Rainey Harper lured him to the new University of Chicago, where he remained officially for exactly a generation and where his students in advanced composition found him terrifyingly frigid in the classroom but sympathetic and understanding in their personal conferences. During his later years the spot of earth dearest to his heart was York Viliage, Maine, but after his retirement from teaching he brought his career to a rather amazing close as government secretary of the Virgin islands, He died at St. Thomas on December 23, 1938.

Passage 2

There are two main kinds of sloth; the two-toed and the three-toed. Of these, the three-toed is considerably the more slothful. It hangs upside down from a branch suspended by hook-like claws at the ends of its long bony arms. It feeds on only one kind of leaf, Cecropia, which happily for the sloth grows in quantity and is easily found. No predators attack the sloth-few indeed can even reach it-and nothing competes with it for the Cecropia. Lulled by this security, it has sunk into an existence that is only just short of complete torpor. It spends eighteen out of twenty-four hours soundly asleep. It pays such little attention to its personal hygiene that green algae grow on its coarse hair and communities of a parasitic moth live in the depths of its coat producing caterpillars which graze on its mouldy hair. Its muscles are such that it is quite incapable of moving at a speed of over a kilometer an hour even over the shortest distances and the swiftest movement it can make is a sweep of its hooked arm. It is virtually dumb and its hearing is so poor that you can let off a gun within inches of it and its only response will be to turn slowly and blink. Even its sense of smell, though it is better than ours, is very much less acute than that of most mammals. And it sleeps and feeds entirely alone.

Passage 3

The Montessori method of educating children is guided by perhaps a half–dozen major principles of education. The first affirms the biological programming of child development, the child's capacity for self – realization, for "auto-education." The second calls for "scientific pedagogy." A science of childhood based on observation. The third demands a natural environment in which self-development can be expressed and observed. Montessori believed that the school could be made into such an environment, thus becoming a laboratory for scientific pedagogy. This environment should be determined scientifically. In order to expand, children, left at liberty to exercise their activities, ought to find in their surroundings something organized in direct relation to the children's internal organization. All of these principles imply the next, which Montessori calls the " biological concept of liberty in pedagogy": the child must be free to act spontaneously and to interact with the prepared environment. The entire program is concerned with the individual child; the spontaneity, the needs, the observation, the freedom are always those of the individual. Finally, the modus operandi of the method is sensory training.

1. Which of the following is the best title for the passage?

(A) Principles of the Montessori Method

(B) Modern Principles of Education

(C) Results of the Montessori Method

(D) Stages of Child Development

 

2. In line 6, the phrase "such an environment" refers to which of the following kinds of

environment?

(C) Pedagogical, in which ideology prevails

(D) Natural, in which self-expression prevails

 

3. According to the passage, the Montessori method focuses on

(A) the individual child

(B) pairs of children

(C) small groups of children

(D) large groups of children

 

4. It can be inferred from the passage that the Montessori method was named after a

(A) school

(B) town

(C) person

(D) book

 

5. Which of the following would NOT be advocated by the Montessori method?

(A) Tightly controlling children's group activities

(B) Carefully teaching children to listen and observe

(B) Permitting children to work at their own pace

(C) Allowing children to speak out at will during classes

 

 

Passage 4

In an experiment designed to study the effect of majority opinion, even when it is contrary to fact, small groups of subjects observed a standard straight line, and then judged which of three other lines equaled it in length. One of the other lines was longer, one shorter, one equal to the

standard; the differences were great enough that threshold judgments were not involved. All but one member of each group had been instructed to agree upon a wrong answer for a majority of the trials. The experimental subject was thus pitted against a majority, and the subject's problem was whether to disagree with the majority, or to doubt his or her own judgment and agree. Many subjects refused to change, and continued to hold to their independent appraisals. But a substantial number yielded under pressure from the others' apparent judgments. The amount of yielding depended upon the clarity of conditions (lack of clarity led to conformity to majority opinion), individual differences, and the size and unanimity of the opposition. With the opposition of only one other person there was very little yielding; with tow against one the amount of yielding became pronounced; and a majority of three was nearly as effective as larger majorities against the lone dissenter.

1. What does the passage mainly discuss?

(A) The accuracy of threshold judgments.

(B) The inability of groups to estimate correct line length.

(A) Two

(B) Three

(C) Four

3. Why did all but one of the members of each group choose the wrong line?

(A) They could not accurately judge which lines were equal in length.

(B) They were told to do so for the purposes of the study.

(C) They wanted to humiliate the person who disagreed.

(D) They did not understand the instructions.

 

4. It can be inferred from the passage that the main purpose of the experiment was to examine

the tendency that many people have to

(A) compete

(B) conform

(C) criticize

(D) communicate

 

5. The experiment described in the passage was most likely carried out by

(A) physicists

(B) mathematicians

(C) linguists

(D) psychologists

 

 

 

Passage 5

This vertical movement of the fieldstones is not simply an artifact of soil erosion, it is the result of frost heaving. In the fall the soil freezes first beneath stones, because stones are a better conductor of heat than soil. Or, put another way, soil is a better insulator than rock in a sea of insulation, stones are chilly islands.

Because most glacial till has a fairly high water content, ice forms beneath fieldstones when they freeze, and the expansion of this ice forces them upward. Even when the ice thaws, the stones do not return to their original positions because during thawing particles of soil seep into

the cavity beneath, partially preventing the stones from dropping. Like a ratchet on a car jack each freeze-thaw cycle gradually lifts the fieldstones toward the surface. Ina very cold winter there may actually be two thrusts per freeze. Ice expands when it initially forms, but as the temperature plummets, the ice contracts. In the reverse process, when this very cold ice finally melts, it must expand a second time, pushing the stone once more.

In theory, the upward movement of fieldstones should result in pure soil, all the stones above the frost line having been pushed to the surface and carried away. What a vision! Acres of pure, deep soil and crowbars rusting away unused. Alas, the fastest stones move only an inch or so a year, and most are orders of magnitude slower.

4. In the first paragraph, the author gives an example of

(A) glacier movement

(B) soil erosion

(C) climate change

(D) heat conduction

Passage 8

A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun's very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is liberated at the center of the Sun as billions upon billions of nucl ei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and, in doing so, release some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of years.

The nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun, to be re-emitted at slightly longer wavelengths. This radiation, in its turn, is absorbed and re-emitted. As the energy filters through the layers of the solar interior, it passes through the x-ray part of the spectrum, eventually becoming light. At this stage, it has reached what we call the solar surface, and can escape into space, without being absorbed further by solar atoms. Avery small fraction of the Sun's light and heat is emitted in such directions that, after passing unhindered through interplanetary space, it hits the Earth.

(A) the production of solar light and heat

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

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

The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically

2017年01月07日托福口语考题回忆 Task 1 The university wants to provide student more entertainments and three choices provided below, which do you prefer and why. l A theater performance by the student actors l A concert provided by professional musician l A lecture from a professor Sample Answer: Well, as a student, I will choose a theater performance by the student actors. For one thing, this kind of activity will improve their cooperation skills. To be more specific, a theater performance includes the whole process of organizing, participating, and promoting an event. Whether the student director or the actor take the responsibility to achieve his/her duty, so this is a great opportunity for them to learn how to deal with other people. Moreover, a performance could greatly inspire them to be more creative. I mean, in order to make a good show, students may have lots of difficulties to cope with, so they have to be flexible to face any emergency. As a result, they may come up with lots of new ideas to make it. Because of these two reasons, I believe this is the best choice. (140 words) Task 2 Friends may disagree with each other, and still maintain friendship. Do you agree with or disagree with this idea, why Sample Answer: Of course I agree with this idea. Firstly people are bound to be different. We have various family background as well as education background even though we are friends. So it is quite naturally that there come up different ideas toward one problem. For example I like watching movie in the movie theatre while my best friend Amy hate sitting in the dark place. But I never require her to go with me; we are still very close friends. Also, the friend who holds a different attitude with me sometimes could inspire me to think from another way. Maybe a very sharp discussion can lead me to an inspiring idea. After all, the experiences and knowledge of one person is limited. For me, I like the friend who are differ from me.

They were both creatures and creators of communities, as well as symptoms of the frenetic quest for community. Even in the first part of the nineteenth century, Americans were already forming the habit of gathering from all corners of the nation for both public and private, business and pleasure purposes. Conventions were the new occasions, and hotels were distinctively American facilities making conven- tions possible. The first national convention of a major party to choose a candidate for President (that of the National Republican party, which met on December 12, 1831, and nominated Henry Clay for President) was held in Baltimore, at a hotel that was then reputed to be the best in the country. The presence in Baltimore of Barnum s City Hotel, a six-story building with two hundred apartments helps explain why many other early national political conventions were held there. In the longer run, too. American hotels made other national conventions not only possible but pleasant and convivial. The growing custom of regularly assembling from afar the representatives of all kinds of groups - not only for political conventions, but also for commercial, professional, learned, and avocational ones - in turn supported the multiplying hotels. By mid-twentieth century, conventions accounted for over a third of the yearly room occupancy of all hotels in the nation, about eighteen thousand different conventions were held annually with a total attendance of about ten million persons. Nineteenth-century American hotelkeepers, who were no

They were at the cutting edge of social change. It was in the cities that the elements that can be associated with modern capitalism first appeared — the use of money and commercial paper in place of barter, open competition in place of social deference and hierarchy, with an attendant rise in social disorder, and the appearance of factories using coat or water power in place of independent craftspeople working with hand tools. "The cities predicted the future," wrote historian Gary. B. Nash, "even though they were but overgrown villages compared to the great urban centers of Europe, the Middle East and China." Except for Boston, whose population stabilized at about 16,000 in 1760, cities grew by exponential leaps through the eighteenth century. In the fifteen years prior to the outbreak of the War for independence in 1775, more than 200,000 immigrants arrived on North American shores. This meant that a population the size of Boston was arriving every year, and most of it flowed into the port cities in the Northeast. Philadelphia's population nearly doubted in those years, reaching about 30,000 in 1774, New York grew at almost the same rate, reaching about 25,000 by 1775. The quality of the hinterland dictated the pace of growth of the cities. The land surrounding Boston had always been poor farm country, and by the mid-eighteenth century it
