第一篇

The evolution of intelligence among early large mammals of the grasslands was due in great measure to the interaction between two ecologically synchronized groups of these animals, the hunting carnivores and the herbivores that they hunted. The interaction resulting from the differences between predator and prey led to a general improvement in brain functions; however, certain components of intelligence were improved far more than others.

The kind of intelligence favored by the interplay of increasingly smarter catchers and increasingly keener escapers is defined by attention—that aspect of mind carrying consciousness forward from one moment to the

next. It ranges from a passive, free-floating awareness to a highly focused, active fixation. The range through these states is mediated by the arousal system, a network of tracts converging from sensory systems to integrating centers in the brain stem. From the more relaxed to the more vigorous levels, sensitivity to novelty is increased. The organism is more awake, more vigilant; this increased vigilance results in the apprehension of ever more subtle signals as the organism becomes more sensitive to its surroundings. The processes of arousal and concentration give attention its direction. Arousal is at first general, with a flooding of impulses in the brain stem; then gradually the activation is channeled. Thus begins concentration, the holding of consistent images. One meaning of intelligence is the way in which these images and other alertly searched information are used in the context of previous experience. Consciousness links past attention to the present and permits the integration of details with perceived ends and purposes.

The elements of intelligence and consciousness come together marvelously to produce different styles in predator and prey. Herbivores and carnivores develop different kinds of attention related to escaping or chasing. Although in both kinds of animal, arousal stimulates the production of adrenaline and norepinephrine by the adrenal glands, the effect in herbivores is primarily fear, whereas in carnivores the effect is primarily aggression. For both, arousal attunes the animal to what is

ahead. Perhaps it does not experience forethought as we know it, but the animal does experience something like it. The predator is searchingly aggressive, innerdirected, tuned by the nervous system and the adrenal hormones, but aware in a sense closer to human consciousness than, say, a hungry lizard’s instinctive snap at a passing beetle. Using past events as a framework, the large mammal predator is working out a relationship between movement and food, sensitive to possibilities in cold trails and distant sounds—and yesterday’s unforgotten lessons. The herbivore prey is of a different mind. Its mood of wariness rather than searching and its attitude of general expectancy instead of anticipating are silk-thin veils of tranquility over an explosive endocrine system.

1. The author is primarily concerned with

(A) disproving the view that herbivores are less intelligent than carnivores

(B) describing a relationship between animals’ intelligence and their ecological roles

(C) establishing a direct link between early large mammals and their modern counterparts

(D) analyzing the ecological basis for the dominance of some carnivores over other carnivores（B）

(E) demonstrating the importance of hormones in mental activity

2. It can be inferred from the passage that in animals less intelligent than the mammals discussed in the passage

(A) past experience is less helpful in ensuring survival

(B) attention is more highly focused

(C) muscular coordination is less highly developed

(D) there is less need for competition among species（A）

(E) environment is more important in establishing the proper ratio of prey to predator

3. The author’s attitude toward the mammals discussed in the passage is best described as

(A) superior and condescending

(B) lighthearted and jocular

(C) apologetic and conciliatory

(D) wistful and tender（E）

(E) respectful and admiring

4. The author provides information that would answer which of the following questions?

I. Why is an aroused herbivore usually fearful?

II. What are some of the degrees of attention in large mammals?

III. What occurs when the stimulus that causes arousal of a mammal is removed?

(A) I only

(B) III only

(C) I and II only

(D) II and III only（C）

(E) I, II and III

5. According to the passage, as the process of arousal in an organism continues, all of the following may occur EXCEPT:

(A) the production of adrenaline

(B) the production of norepinephrine

(C) a heightening of sensitivity to stimuli

(D) an increase in selectivity with respect to stimuli（E）

(E) an expansion of the range of states mediated by the brain stem

第二篇

We can distinguish three different realms of matter, three levels on the quantum ladder. The first is the atomic realm, which includes the world

of atoms, their interactions, and the structures that are formed by them, such as molecules, liquids and solids, and gases and plasmas. This realm includes all the phenomena of atomic physics, chemistry, and, in a certain sense, biology. The energy exchanges taking place in this realm are of a relatively low order. If these exchanges are below one electron volt, such as in the collisions between molecules of the air in a room, then atoms and molecules can be regarded as elementary particles. That is, they have “conditional elementarity” because they keep their identit y and do not change in any collisions or in other processes at these low energy exchanges. If one goes to higher energy exchanges, say 104 electron volts, then atoms and molecules will decompose into nuclei and electrons; at this level, the latter particles must be considered as elementary. We find examples of structures and processes of this first rung of the quantum ladder on Earth, on planets, and on the surfaces of stars.

The next rung is the nuclear realm. Here the energy exchanges are much higher, on the order of millions of electron volts. As long as we are dealing with phenomena in the atomic realm, such amounts of energy are

unavailable, and most nuclei are inert: they do not change. However, if one applies energies of millions of electron volts, nuclear reactions, fission and fusion, and the processes of radioactivity occur; our elementary particles then are protons, neutrons, and electrons. In addition, nuclear processes produce neutrinos, particles that have no detectable mass or charge. In the universe, energies at this level are available in the centers of stars and in star explosions. Indeed, the energy radiated by the stars is produced by nuclear reactions. The natural radioactivity we find on Earth is the long-lived remnant of the time when now-earthly matter was expelled into space by a major stellar explosion.

The third rung of the quantum ladder is the subnuclear realm. Here we are dealing with energy exchanges of many billions of electron volts. We encounter excited nucleons, new types of particles such as mesons, heavy electrons, quarks, and gluons, and also antimatter in large quantities. The gluons are the quanta, or smallest units, of the force (the strong force) that keeps the quarks together. As long as we are dealing with the atomic or nuclear realm, these new types of particles do not occur and the nucleons remain inert. But at subnuclear energy levels, the nucleons and mesons appear to be composed of quarks, so that the quarks and gluons figure as (figure as: 扮演...角色) elementary particles.

1. According to the passage, radioactivity that occurs naturally on Earth is the result of

(A) the production of particles that have no detectable mass or electric charge

(B) high energy exchanges on the nuclear level that occurred in an ancient explosion in a star

(C) processes that occur in the center of the Sun, which emits radiation to the Earth

(D) phenomena in the atomic realm that cause atoms and molecules to decompose into nuclei and electrons（B）

(E) high-voltage discharges of electricity that took place in the atmosphere of the Earth shortly after the Earth was formed

2. The author organizes the passage by

(A) making distinctions between two groups of particles, those that are elementary and those that are composite

(B) explaining three methods of transferring energy to atoms and to the smaller particles that constitute atoms

(C) describing several levels of processes, increasing in energy, and corresponding sets of particles, generally decreasing in size

(D) putting forth an argument concerning energy levels and then conceding that several qualifications of that argument are necessary（C）(E) making several successive refinements of a definition of elementarity on the basis of several groups of experimental results

3. According to the passage, which of the following can be found in the atomic realm?

(A) More than one level of energy exchange

(B) Exactly one elementary particle

(C) Exactly three kinds of atomic structures

(D) Three levels on the quantum ladder（A）

(E) No particles smaller than atoms

4. According to the author, gluons are not

(A) considered to be detectable

(B) produced in nuclear reactions

(C) encountered in subnuclear energy exchanges

(D) related to the strong force（B）

(E) found to be conditionally elementary

5. At a higher energy level than the subnuclear level described, if such

a higher level exists, it can be expected on the basis of the information in the passage that there would probably be

(A) excited nucleons

(B) elementary mesons

(C) a kind of particle without detectable mass or charge

(D) exchanges of energy on the order of millions of electron volts（E）

(E) another set of elementary particles

考博英语作文实用范文：真人秀 考博英语作文实用范文：真人秀 What emerges into our sights is a familiar yet far-reaching picture that there are a wide range of reality shows in front of a middle-aged man who, half lying on the sofa, is swinging a remote device in his hand with a confused face, wondering which one is the best to choose. The meaning revealed by the picture is that reality shows have hit into our common cultural market. On the one hand, not only does this sort of consumer culture drives the improvement of cultural industry, but also it exerts a strong influence on our daily life, such as being informed of local customs and folklore from place to place, relieving the pressure derived from our working class’regular work and so on. On the other hand, it is the wide spread of this form of entertainment that makes it difficult to present the real, cultural contents but only stays in the half-hearted nature. What’s worse, what the increasing imitative behaviors brings about, to a new high, is the national over-consumption. As for me, the type of reality shows is a special product of the economic and social development that produces more benefits but less adverse impact. However, it is imperative for us, common people, to take a rational yet responsible attitude to the life we lead, especially the kind of activity we are obsessed with.

Reading Comprehension (35 minutes) Directions:There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage One Questions 21 to 25 are based on the following passage: When Kathie Gifford ’s face was splashed across the newspapers in 1996 after her lucrative line of Wal mart clothing was exposed as the work of underpaid laborers in New York City ’s Chinatown, the Department of Labor and the White House teamed up to condemn such practices. With much fanfare, President Clinton’s administration launched the “No Sweat” campaign, which pressured retailers and manufacturers to submit to periodic independent inspection of their workplace conditions.; This campaign urged manufacturers to sign the Workplace Code of Conduct, a promise to self regulate that has since been adopted by a handful of retailers and many of the nation ’s largest manufacturers, including Nike and L.L. Bean. However, the Department of Defense, which has a $ 1 billion garment business that would make it the country’s 14th largest retail apparel outlet, has not signed the Code of Conduct. In addition, it has not agreed to demand that its contractors submit to periodic inspections.; Because the Department of Defense has not agreed to adhere to the code, the job of stopping public sector sweatshops falls to the Department of Labor. Federal contractors that persist in violating wage laws or safety and health codes can lose their lucrative taxpayer financed contracts. But Suzanne Seiden, a deputy administrator at the Department of Labor, says that to her knowledge, the department has never applied that rule to government apparel manufacturers. “I just assume that they are adhering to safety and health requirements,” she says. According to records obtained by Mother Jones, through a Freedom of Information Act request, the Occupational Safety and Health Administration has cited Lion 32 times for safety and health violations in the past 12 years. 21.What is this passgage mainly concerned with? A)The functions of the Department of Labor in America. B)A serious problem threatening American economy. C)The successful attempt of regulating sweatshops in America. D)The seriousness of the problem of sweatshops in America. 22.According to the passage, Kathie Gifford ____. A) was one of the underpaid laborers in New York City’s Chinatown B) was one of the well paid laborers in New York City ’s Chinatown C) made much money from cheap laborers in New York City’s Chinatown D) wrote a newspaper article exposing the practice of employing cheap laborers 23.The underlined p hrase “to submit to” is closest in meaning to ____. A) to accept unwillingly B) to refuse coldly C) to welcome warm heartedly D) to blame strongly 24.Which of the following statements about the Department of Defense is true? A) It will become the count ry’s 14th largest retail apparel manufacturer. B) It hasn’t acted according to the Workplace Code of Conduct. C) It has demanded its contractors to sign the Workplace Code of Conduct. D) It has teamed up with the Department of Labor to launch a campaign. 25.What was the purpose of President Clinton’s administration launching the “No Sweat” campaign? A) To urge manufacturers to obey the Workplace Code of Conduct. B) To remind the manufacturers of the Workplace Code of Conduct. C) To urge the Department of Labor to take its responsibility. D) To urge the Department of Defense to inspect manufacturers. Passage Two Questions 26 to 30 are based on the following passage: The term investment portfolio conjures up visions of the truly rich-the Rockefellers, the Wal Mart Waltons, Bill Gates. But today, everyone-from the Philadelphia firefighter, his part time receptionist wife and their three children, to the single Los Angeles lawyer starting out on his own-needs a portfolio.; A portfolio is simply a collection of financial assets. It may include real estate, rare stamps and coins, precious metals and even artworks. But those are for people with expertise. What most of us need to know about are stocks, bonds and cash (including such cash equivalents as money market funds).; How do you decide what part of your portfolio should go to each of the big three? Begin by understanding that stocks pay higher returns but are more risky; bonds and cash pay lower returns but are less risky.; Research by Ibbotson Associates, for example, shows that large company stocks, on average, have returned 11.2 percent annually since 1926. Over the same period, by comparison, bonds have returned an annual average of 5.3 percent and cash, 3.8 percent.; But short term risk is another matter. In 1974, a one year $1000 investment in the stock market would have declined to $735.; With bonds, there are two kinds of risk: that the borrower won’t pay you back and that the money you’ll get won’t be worth very much. The U.S. government stands behi nd treasury bonds, so the credit risk is almost nil. But the inflation risk remains. Say you buy a $1000 bond maturing in ten years. If inflation averages about seven percent over that time, then the $1000 you receive at maturity can only buy $500 worth of today’s goods.; With cash, the inflation risk is lower, since over a long period you can keep rolling over your CDs every year (or more often). If inflation rises, interest rates rise to compensate.; As a result, the single most imortant rule in building a portfolio is this: If you don’t need

We should make our utmost efforts to preserve intangible heritages because, without heir physical form of existence, they are in greater risk of extinction. 如同长城、故宫之类的物质文化遗产一样，像京剧和祭孔仪式这类非物质文化遗产，也同样至关重要。 我们应不遗余力地去保护非物质遗产，因为它们在不具备物质存有的条件下，失传的可能性更加岌岌可危。 According to UNESCO's Convention for the Safeguarding of Intangible Cultural Heritage (2003), all forms of social customs and habits, folklore, performing arts, rituals, oral traditions, festivals, traditional crafts and various knowledge and practices about nature and universe can be classified as intangible cultural heritages. As a country consisting of a great diversity of ethnic groups and with time-honored history and civilization, China abounds in intangible cultural heritages. Cultural heritages connect modern people with the historical past, allowing them to acquire a cultural and historical identity. Without cultural heritages, we would be rendered absolutely rootless and we would find it hard to cope with challenges at present and in the future.

For better and worse, it's a milestone. And there will be more milestones ahead. Fourteen years from now, there are expected to be 8 billion people on the planet. Most of the growth will occur in the world's poorer countries. Proportionally, Europe's population will decline, while Africa's will increase. At around the same time, India will overtake China as the most populous nation on Earth. The growing global population is just one side of the coin. A recent report from the World Health Organization signaled the seriousness of the human population explosion: more than 3 billion people — about half the world's population — are malnourished. Never before have so many, or such a large proportion, of the world's people been malnourished. And in a growing number of countries there is a seemingly unstoppable march toward sub-replacement fertility, whereby each new generation is less populous than the previous one, and population aging. As a result of declining fertility and increasing longevity, the populations of more and more countries are aging raging rapidly. Between 2005 and 2050, a rise in the population aged 60 years or over will be visible, whereas the number of children(persons under age 15)will decline slightly. Population aging represents, in one sense, a success story for mankind, but it also poses profound challenges to public institutions that must adapt to a changing age structure. The latest national census in China shows the number of elderly people in the country has jumped to more than 13. 3 percent of the population, an increase of nearly 3 percentage points on the percentage from the previous census in 2000. A quarter of the country's population will be over 65 by 2050, according to the National Population and Family Planning Commission. The growing number of elderly is a challenge that the government needs to tackle, we can't rely on the ever-increasing population to support them or maintain the nation's economic growth. Better solutions are needed, such as raising retirement ages to reflect the greater longevity and working capability of today's older adults and making adjustments so pension programs are more accessible. It was heartening to hear the Ministry of Human Resources and Social Security spokesperson announced in Beijing on Tuesday that the government will take retirement policy seriously and proactively. Shanghai began testing a flexible retirement system last October. Eligible employees in the private sector are allowed to postpone retirement until the age of 65 for men and 60 for women. Public servants, however, will continue to retire under the present system age 60 for men and 55 for women.（分数：10.00） (1).According to the passage, India will______in 14 years.（分数：2.00） A.be a poorer country B.be the most populous country C.decline in population D.increase investment in Africa (2).What problem will result from the global population explosion?（分数：2.00） A.Population aging.
