As in the case of so many words used by the biologist and physiologist, the word acclimatization is hard to define. With increase in knowledge and understanding, meanings of words change. Originally the term acclimatization was taken to mean only the ability of human beings or animals or plants to accustom themselves to new and strange climatic conditions, primarily altered temperature. A person or a wolf moves to a hot climate and is uncomfortable there, but after a time is better able to withstand the heat. But aside from temperature, there are other aspects of climate. A person or an animal may become adjusted to living at higher altitudes than those it was originally accustomed to. At really high altitudes, such as aviators may be exposed to, the low atmospheric pressure becomes a factor of primary importance. In changing to a new environment, a person may, therefore, meet new conditions of temperature or pressure, and in addition may have to contend with different chemical surroundings. On high mountains, the amount of oxygen in the atmosphere may be relatively small; in crowded cities, a person may become exposed to relatively high concentrations of carbon dioxide or even carbon monoxide, and in various areas may be exposed to conditions in which the water content of the atmosphere is extremely high or extremely low. Thus in the case of humans, animals, and even plants, the concept of acclimatization includes the phenomena of increased toleration of high or low temperature, of altered pressure, and of changes in the chemical environment.Let us define acclimatization, therefore, as the process in which an organism or a part of an organism becomes used to an environment which is normally unsuitable to it or lethal for it. By and large, acclimatization is a relatively slow process. The term should not be taken to include relatively rapid adjustments such as our sense organs are constantly making. This type of adjustment is commonly referred to by physiologists as “adaptation”.Thus our touch sense soon becomes accustomed to the pressure of our clothes and we do not feel them; we soon fail to hear the ticking of a clock; obnoxious odors after a time fail to make much impression on us, and our eyes in strong light rapidly become insensitive.The fundamental fact about acclimatization is that all animals and plants have some capacity to adjust themselves to changes in their environment. This is one of the most remarkable characteristics of living organisms, a characteristic for which it is extremely difficult to find explanations.1. According to the reading selection, all animals and plants( ).2. It can be inferred from the reading selection that( ).3. According to the reading selection, acclimatization( ).4. By inference from the reading selection, which one of the following would not require the process of acclimatization? 5.

Scientists are hoping to eliminate malaria (疟疾)by developing a genetically modified mosquito that cannot transmit the disease. Malaria has long troubled the populations of South America, Africa, and Asia, where mosquito bites infect up to 500 million people a year with this serious and sometimes fatal parasitic blood disease. For generations, scientists have been trying to eliminate malaria by developing new drugs and using pesticide (杀虫剂)to wipe out local mosquito populations. But these measures aren’t working — and some scientist, like Greg Lanzaro, say that because of drug resistance and population changes, malaria is actually more prevalent now than it was 20 years ago. Lanzaro says he has a better way to stop the spread of malaria: genetically modifying mosquitoes so they are unable to carry the disease.Lanzaro and his colleagues are planning a multi-year project to produce malaria-resistant mosquitoes and he thinks they can do it within five years. “We can get foreign into mosquitoes and they go where they’re supposed to go,” Lanzaro says, pointing out that scientists have already succeeded in genetically engineering mosquitoes that cannot transmit malaria to birds and mice. And he says, scientists are quickly making progress on genes that block transmission of the disease to humans as well.The most difficult part scientifically, Lanzaro says, is figuring out how to get the lab-engineered mosquitoes to spread their genes into natural populations. After all, he points out; it’s useless to engineer mosquitoes in the lab that can’t transmit malaria when there are millions out in the wild that can. To solve this problem, Lanzaro wants to load up a mobile piece of DMA with the malaria-resistant gene, and then insert it into a group of mosquito embryos. The malaria-resistant gene would be integrated directly into the mosquitoes’ DNA, making it impossible for those mosquitoes to transmit the parasite that causes malaria. In this way a small group of lab-raised mosquitoes could be released into the wild, and by interbreeding with wild mosquitoes, eventually transmit the beneficial gene to the entire population.61. One reason for malaria to be more widespread now is that ( ).A. more people have moved to malaria-infected areasB. mosquitoes have become resistant to pesticidesC. genetically modified mosquitoes still transmit the diseaseD. mosquitoes bite as many as 500 million people a year62. Lanzaro is hopeful that in a few year man can( ).A. start to eliminate malariaB. cure parasitic blood diseasesC. prevent mice from transmitting parasitesD. acquire immunity against malaria63. Lanzaro is confident that scientist can block the transmissions of malaria to humans because( ).A. natural mosquito populations do not changeB. scientists have succeeded with birds and miceC. foreign genes always go where they are requiredD. lab-raised mosquitoes will not be resistant to drugs64. What is the most difficult part of Lanzaro’s project?A. Spreading malaria-resistant genes into natural mosquito populations.B. Raising malaria-resistant mosquitoes.C. Making genes that block the transmission of malaria.D. Identifying malaria-resistant genes.65. According to the passage, a fundamental way to wipe out malaria is to( ).A. develop new malaria-resistant drugsB. produce effective pesticides to kill mosquitoesC. change the genetic makeup of mosquitoesD. remove people from malaria-infected areas

The age at which young children begin to make moral discrimination about harmful actions committed against themselves or others has been the focus of recent research into the moral development of children. Until recently, child psychologists supported pioneer developmentalist Jean Piaget in his hypothesis that because of their immaturity, children under age seven do not take into account the intentions of a person committing accidental or deliberate harm, but rather simply assign punishment for transgressions on the basis of the magnitude of the negative consequences caused. According to Piaget, children under age seven occupy the first stage of moral development, which is characterized by moral absolutism (rules made by authorities must be obeyed) and imminent justice (if rules are broken, punishment will be meted out). Until young children mature, their moral judgments are based entirely on the effect rather than the cause of a transgression. However, in recent research, Kensey found that six-year-old children not only distinguish between accidental and intentional harm, but also judge intentional harm as naughtier, regardless of the amount of damage produced. Both of these findings seem to indicate that children, at an earlier age than Piaget claimed, advance into the second stage of moral development, moral autonomy, in which they accept social rules but view them as more arbitrary than do children in the first stage.Kensey’s research raises two key questions for developmental psychologists about children under age seven: do they recognize justifications for harmful actions, and do they make distinctions between harmful acts that are preventable and those acts that have unforeseen harmful consequences? Studies indicate that justifications excusing harmful actions might include public duty, self-defense, and provocation. For example, Nesdalc and Rule concluded that children were capable of considering whether or not an aggressor’s action was justified by public duty; five year olds reacted very differently to “Bonnie wrecks Ann’s pretend house” depending on whether Bonnie did it “so somebody won’t fall over it” or because Bonnie wanted “to make Ann feel bad.” Thus, a child of five begins to understand that certain harmful actions, though intentional, can be justified: the constraints of moral absolutism no longer solely guide their judgments.Psychologists have determined that during kindergarten children learn to make subtle distinctions involving harm. Darley observed that among acts involving unintentional harm, six-year-old children just entering kindergarten could not differentiate between foreseeable, and thus preventable, harm and unforeseeable harm for which the perpetrator cannot be blamed. Seven months later, however, Darley found that these same children could make both distinctions, thus demonstrating that they had become morally autonomous.1. Which of the following best describes the passage as a whole?2. Darley found that after seven months of kindergarten six year olds acquired the ability of( ).3. According to the passage, Piaget and Kensey would not have agreed on( ).4. The term “public duty”(in line 5 of paragraph 2)in the context of the passage means( ).5. Kensey’s findings support which of the following conclusions about six-year-old children?

Some people say that the study of liberal arts is a useless luxury we cannot afford in hard times. Students, they argue, who do not develop salable kills will find it difficult to land a job upon graduation. But there is a problem in speaking of “salable skills”. What skills are salable? Right now, skills for making automobiles are not highly salable, but they have been for decades and might be again. Skills are another example of varying salability, as the job market fluctuates. What’s more, if one wants to build a curriculum exclusively on what is salable, one will have to make the courses very short and change them very often, in order to keep up with the rapid changes in the job market. But will not the effort be in vain? In very few things can we be sure of future salability, and in a society where people are free to study what they want, and work where they want, and invest as they want, there is no way to keep supply and demand in labor in perfect accord.A school that devotes itself totally to salable skills, especially in a time of high unemployment, sending young men and women into the world armed with only a narrow range of skills, is also sending lambs into the lion’s den. If those people gain nothing more from their studies than supposedly salable skills, and can’t make the sale because of changes in the job market, they have been cheated. But if those skills were more than salable, if study gave them a better understanding of the world around them and greater adaptability in a changing world, they have not been cheated. They will find some kind of job soon enough. Flexibility, and ability to change and learn new things, is a valuable skill. People who have learned how to learn can learn outside of school. That is where most of us have learned to do what we do, not in school. Learning to learn is one of the highest liberal skills.1. From the passage, we can learn that the author is favor of( ).2. The word “fluctuate” (Line5, Para. 1) most probably means( ).3. According to the author, who of the following is more likely to get a job in times of high unemployment?4. According to the author, in developing a curriculum school should( ).5. We can learn from the passage that( ).

The first reaction one has to the question of viable approaches to the control of chemical and biological weapons is that there are no such approaches. And it is most difficult to dispense with this first reaction. The reasons are that the nations, including some of the smaller ones, are already downstream too far. The larger stores of weapons for CB warfare may be restricted to the major powers, but there is little doubt that an increasing capability is proliferating to some of the smaller and developing countries. What used to be largely a picture of research has turned to development, and development has turned to manufacturing and stockpiling. The subject is shrouded in secrecy and it is the secrecy which seems to provide a nonstop momentum to realize the full potential of these types of weapons. No one really knows what someone else may have ready for employment in a military situation. The large and expensive programs in the United States and Russia are attributed to each other’s “large and expensive programs”. Knowledge and capability required for detection and defense are tied to knowledge and capability for retaliation. The “no first use” policy of the United States and other major nations implies that this retaliation be in kind, and this requires that weapons of the CB class be available.A philosophy of mutual deterrence (制约) is developing in CB warfare comparable to that in nuclear warfare. In fact, much of the literature on the subject repeats that the stalemate in the latter opens up the need for capability in the former. As an arms race, CBW does not present the spiraling costs of the ICBM-ABM systems, hence a movement to CB weapons (especially chemical) among some smaller nations. So far as the major powers are concerned, the elements in CBW which are in common with the nuclear arms race include the now-accepted approach to that race. Thus in discussing control of CB warfare, an editorial in the British journal, Nature, concluded: “The balance of terror between the great power blocs may not be to everybody’s taste, but it is probably still the best way of avoiding War.”1. It can be inferred that the control of chemical and biological warfare( ).2. Which of the following is NOT given as a cause for the continued development of CB weapons?3. The writer in the British journal might feel that the research and development of CB systems should be( ).4.

Over the past decade, American companies have tried hard to find ways to discourage seniors from feathering their own nests at expense of their shareholders. The three most popular reforms have been recruiting more outside directors in order to make boards more independent, linking bosses’ pay to various performance measures, and giving bosses share options, so that they have the same long-term interests as their shareholders.These reforms have been widely adopted by American’s larger companies, and surveys suggest that many more companies are thinking of following their lead. But have they done any good? Three papers presented at the annual meeting of the Academy of Management in Boston this week suggest not. As is usually the case with boardroom tinkering, the consequences have differed from those intended.Start with those independent boards. On the face of it, dismissing the boss’s friends from the board and replacing them with outsiders looks a perfect way to make senior managers more accountable. But that is not the conclusion of a study by Professor James Westphal. Instead he found that bosses with a boardroom full of outsides spend much of their time building alliances, doing personal favors and generally pleasing the outsiders.All too often, these seductions succeed. Mr. Westphal found that, to a remarkable degree, “independent” boards pursue strategies that are likely to favor senior managers rather than shareholders. Such companies diversify their business, increase the pay of executives and weaken the link between pay and performance.To assess the impact of performance related pay, Mr. Westphal asked the bosses of 103 companies with states of over $1 billion what measurements were used to determine their pay. The measurements varied widely, ranging from sales to earnings per share. But the researcher’s big discovery was that bosses attend to measures that affect their own incomes and ignore or play down other factors that affect a company’s overall-success.In short, bosses are quick to turn every imaginable system of corporate government to their advantage — which is probably why they are the people who are put in charge of things. Here is a paradox for the management theorists: any boss who cannot beat a system designed to keep him under control is probably not worth having.1. What is the purpose of the large companies in recruiting outsiders and putting them on the board of directors?2. What does Professor James Westphal’s study suggest?3. The word “seduction” (Line 1, Para. 4) probably means( ).4. Which of the following statements is true?5. How does the author feel about the efforts to control senior executives?
