Exercise 3
Impressions of America(Excerpts)Oscar WildeI fear I cannot picture America as altogether an Elysium- perhaps, from the ordinary standpoint and I know little about the country. I cannot give its latitude or longitude; I cannot compute the value of its dry goods, and I have no very close acquaintance with its politics. These are matters which may not interest you, and they certainly are not interesting to me.The first thing that struck me on landing in America was that if the Americans are not the most well-dressed people in the world, they are the most comfortable dressed. Men are seen there with the dreadful chimney-pot hat, but there are very few hatless men; men wear the shocking swallow-tail coat, but few are to be seen with no coat and all. There is an air of comfort in the appearance of the people which is a marked contrast to that seen in this country; where, too often and, people are seen in close contact with rags.The next thing particularly noticeable is that everybody seems in a hurry to catch a train. This is a state of things which is not favorable to poetry or romance. Had Romeo or Juliet been in a constant state of anxiety about trains, or had their minds been agitated by the question ofreturn-tickets, Shakespeare could not have given us those lovely balcony scenes which are so full of poetry and pathos.参考译文美国印象(节录)王尔德我恐怕不能把美国描绘成十足的天堂—从一般的角度来说,也许我对这个国家所知甚少。

第3章化学热力学的初步概念与化学平衡一、要点1.化学热力学把热力学的理论、原理、规律以及研究方法,用之于研究化学现象就产生了化学热力学。
它可以解决化学反应中的能量问题、化学反应的方向问题,以及化学反应进行的程度问题。
2.系统与环境系统曾称体系,指化学直接研究的对象,与系统密切相关的部分或与系统相互影响所可及的部分称为环境。
两者之间可以交换物质或能量,据此可把系统分为:①敞开系统:系统和环境之间可以有能量和物质的交换;②封闭系统:系统和环境之间只有能量的交换,而不能有物质的交换;③孤立系统:系统和环境之间既无能量的交换,也无物质的交换。
3.状态和状态函数系统的所有客观性质的综合表现即为系统的状态。
描述系统状态的物理量称之为状态函数。
状态定,状态函数定,即有一定的值;状态变,状态函数的值变。
4.过程和途径系统的状态发生了任意的变化,就说系统发生了一个过程。
分别发生在等温条件下、压强一定条件下和绝热条件下的系统的变化,分别称为“等温过程”、“等压过程”和“绝热过程”。
系统由始态到终态的变化,可经由不同的方式完成,这不同方式即为“途径”。
5.热和功系统和环境间因温度差别引起能量交换,这种被传递的能量称为“热”,用符号Q表示。
并规定当系统吸热时,Q为正值,即Q > 0或ΔQ > 0,放热时Q为负值,即Q < 0或∆Q < 0。
除此之外,其他在系统和环境之间被传递的能量均叫做“功”,用符号W表示。
并规定当系统对环境做功时,W < 0,反之W > 0。
6.热化学研究物质化学和物理变化过程中热效应的学科叫做热化学。
即对于伴随着化学反应和状态的变化而发生的热的变化的测量、解释和分析。
7.热量计用来测量化学反应热效应的装置。
常用的有测量物质恒容燃烧能的弹式热量计,测量物质恒压反应热等热效应的各种微量热量计和测量物质热容的各种低温热量计。
8.热容指物体温度升高1K所需的热量,单位为J·K-1。

3.从此以后,我就特别注意聋哑人的特征,还从他们那里学会了一些常用的手语。
Since then, I've been always paying much attention to the deaf mute and learnt a couple of sign language from them as well. 比如,我可以用哑语问他们:“朋友,您好!” “您到哪里下车?”“您请往里 走!”“谢谢”等等。 For instance, I can greet them in sign language as"Hello, How are you?" " Where will you get off ?" "Go further inside, please." "Thanks!" and so on. 这样,不仅我能更好地为他们服务,与他们进行感情交流,也减少了一些他们与其他 乘客的误会和纠纷。 In this way, not only can I provide them with good service, set up a friendly relation with them, but also decrease the possibility of misunderstanding and dispute between them and other passengers.

1.有一次,在拥挤的车厢门口,我听见一位男乘客客客气气地问 他前面的一个女乘客:“您下车吗?”女乘客没理他。“你下 车吗?”他又问了一遍。女乘客还是没理他。“下车吗?”他 耐不住了,放大声问,那女乘客依然没反应。“你是聋子,还 是哑巴?” 他急了,捅了一下那女乘客,也引得车厢的人都往这里看。女乘 客这时也急了,瞪起一双眼睛回手给了男乘客一拳。 Once, I heard a man, at the gate of the crowded cabin, ask politely a woman standing before him. "Would you get off here?" Receiving no response from the woman, he asked again, "Do you get off ?"Again no response from the woman."Get off" asked her impatiently in a loud voice. But there was still no response at all. The man lost his temper,"You are deaf or dumb?"and gave her a slight push. This caused the rest passengers to look to this way. So angry was the woman at this time that she stared at the man and returened him a blow.

Time Limit 45minsPART II. READINGDirections: There are four 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.Passage 1Research indicates that parents who reward self-control and independence tend to have children with high achievement motivation. Such parents set high standards for their children but allow them to work at their own level and to make their own mistakes. By contrast, parents of low-need achievers typically set impossibly high goals for their children and make extreme demands. In addition, parents of high-need achievers encourage good performance but do not berate their children when they fail. If a child comes home from school with four As and one B on a report card, the parents focus on the As; parents of a potential low-need achiever tend to ask, “Why the B?” Parents of high-need achievers respond to average grades with warmth and suggestions for reasonable goals and ways to reach them. Parents of low-need achievers might say, “You’re dumb and lazy and you’ll never amount to anything”, and punish the child. When a child is having trouble with a math problem, the parent of a potentially high-need achiever will suggest the general procedure and let the child work out the particular solution; a low-need achiever’s parent will solve the problem and then hand the child the answer.That needs for achievements exist within all of us, to varying degrees, is undeniable. And although biological bases for at least the achievement need have been proposed, a great deal more is known about the psychological bases of these needs and how they come about. Closely related to motivation are emotions, which can activate and direct behavior in much the same way as physiological, social, and psychological motivations do.31. according to the passage, parents of low-need achievers ________.A. usually leave their children aloneB. set too high standards for their childrenC. allow for failure on the part of their childrenD. control their children to a minimum degree32. In the fourth sentence of Paragraph 1, the word “berate” probably means ________.A. praiseB. criticizeC. observeD. neglect33. What will parents of high-need achievers do if their children don’t get good marks for allcourses?A. Criticize them for the lower marks and praise them for the good.B. Praise them and give some suggestions for further improvement.C. Praise them for the good marks and reward them.D. Criticize them for the lower marks and punish them.34. If a child has difficulty with his / her homework, a parent of a low-need achiever _______.A. tell him the answer directlyB. give him some suggestionsC. let him solve the problem by himselfD. scold and punish him35. The passage is mainly about the role of ________.A. reward in promoting their children’s studyB. self-control and independence in child growthC. emotional reaction in promoting achievementD. praise in promoting desired behaviorPassage 2Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses — flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症),a rare but serious condition of the liver and central nervous system.There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.36. According to the author, knowing the cause of the misery will help ________. A. shorten the duration of the illness B. the patient buy medicine over the counter C. the patient obtain cheaper prescription drugs D. prevent people from catching colds and the flu37. We learn from the passage that ________. A. one doesn’t need to take any medicine if he has a cold or the flu B. aspirin should not be included in over-the-counter medicines for the flu C. delayed treatment of the flu will harm the liver and central nervous system D. over-the-counter drugs can be taken to ease the misery caused by a cold or the flu38. According to the passage, to combat the flu effectively, ________. A. one should identify the virus which causes it B. one should consult a doctor as soon as possible C. one should take medicine upon catching the disease D. one should remain alert when the disease is spreading39. Which of the following symptoms will distinguish the flu from a cold?A. A stuffy nose.B. A high temperature.C. A sore throatD. A dry cough.40. If children have flu-like symptoms, their parents ________. A. are advised not to give them aspirin B. should watch out for signs of Reye syndrome C. are encouraged to take them to hospital for vaccination D. should prevent them from mixing with people running a feverPassage 3To call someone bird-brained in English means you think that person is silly or stupid. But will this description soon disappear from use in the light of recent research? It seems the English may have been unfair in associating birds' brains with stupidity.In an attempt to find out how different creatures see the world, psychologists at Brown University in the U.S.A. have been comparing the behaviour of birds and humans. One experiment has involved teaching pigeons to recognize letters of the English alphabet. The birds study in “classrooms”, which are boxes equipped with a computer. After about four days of studying a particular letter, the pigeon has to pick out that letter from several displayed on the computer screen. Three male pigeons have learnt to distinguish all twenty-six letters of the alphabet in this way.A computer record of the birds' four-month study period has shown surprising similarities between the pigeons’ and human’s performance. Pigeons and people find the same letters easy, or hard to tell apart. For example, 92 percent of the time the pigeons could tell the letter D from the letter Z. But when faced with U and V(often confused by English children), the pigeons were right only 34 percent of the time.The results of the experiments so far have led psychologists to conclude that pigeons and humans observe things in similar ways. This suggests that there is something fundamental about the recognition process. If scientists could only discover just what this recognition process is, it could be very useful for computer designers. The disadvantage of a present-day computer is that it can only do what a human being has programmed it to do, and the programmer must give the computer precise, logical instructions. Maybe in the future, though, computers will be able to think like human beings.41. The writer suggests that the expression “bird-brained” might be out of use soon because it is ________.A. sillyB. impoliteC. unnecessaryD. inappropriate42. Psychologists have been experimenting with pigeons to find out whether the birds ________. A. are really silly or stupid B. see the world as human beings do C. can learn to make ideas known to people D. learn more quickly than children43. U and V are confused byA. many English childrenB. 92 percent of pigeonsC. most people learning EnglishD. 34 percent of pigeons44. There are similarities in observing things by pigeons and humans ________. A. because pigeons are taught by humans B. because pigeons have brains more developed than other birds C. because pigeons and humans have similar brains D. because their basic ways to know the world are the same45. The research may help A. psychologists B) computer salesmen C. computer designers D) teachersPassage 4If you know exactly what you want, the best route to a job is to get specialized training. A recent survey shows that companies like graduates in such fields as business and health care who can go to work immediately with very little on-the-job training. That’s especially true of booming fields that are challenging for workers. At Cornell’s School of Hotel Administration, for example, bachelor’s degree graduates get an average of four or five job offers with salaries ranging from the high teens to the low 20s and plenty of chances for rapid advancement. Large companies, especially, like a background of formal education coupled with work experience. But in the long run, too much specialization doesn’t pay off. Business, which has been flooded with MBAs, no longer considers the degree an automatic stamp of approval. The MBA may open doors and command a higher salary initially, but the impact of a degree washes out after five years. As further evidence of the erosion (销蚀) of corporate (公司的) faith in specialized degrees, Michigan State’s Scheetz cites a pattern in corporate hiring practices. Although companies tend to take on specialists as new hires, they often seek out generalists for middle- and upper-level management. “They want someone who isn’t constrained (限制) by nuts and bolts to look at the big picture,” says Scheetz. This sounds suspiciously like a formal statement that you approve of the liberal-arts graduate. Time and again labor-market analysts mention a need for talents that liberal-arts majors are assumed to have: writing and communication skills, organizational skills, open-mindedness and adaptability, and the ability to analyze and solve problems. David Birch claims he does not hire anybody with an MBA or an engineering degree. “I hire only liberal-arts people because they have a less-than-canned way of doing things,” says Birch. Liberal-arts means an academically thorough and strict program that includes literature, history, mathematics, economics, science, human behavior — plus a computer course or two. With that under your belt, you can feel free to specialize. “A liberal-arts degree coupled with an MBA or some other technical training is a very good combination in the marketplace,” says Scheetz.46. What kinds of people are in high demand on the job market? A. Students with a bachelor’s degree in humanities. B. People with an MBA degree from top universities. C. People with formal schooling plus work experience.D. People with special training in engineering.47. By saying “... but the impact of a degree washes out after five years” (Line3,Para.3), theauthor means ________. A. most MBA programs fail to provide students with a solid foundation B. an MBA degree does not help promotion to managerial positions C. MBA programs will not be as popular in five years’ time as they are now D. in five years people will forget about the degree the MBA graduates have got48. According to Scheetz’s statement (Lines3-4, Para.4), companies prefer ________. A. people who have a strategic mind B. people who are talented in fine arts C. people who are ambitious and aggressive D. people who have received training in mechanics49. David Birch claims that he only hires liberal-arts people because ________. A) they are more capable of handling changing situations B) they can stick to established ways of solving problems C) they are thoroughly trained in a variety of specialized fields D) they have attended special programs in management50. Which of the following statements does the author support? A) Specialists are more expensive to hire than generalists. B) Formal schooling is less important than job training. C) On-the-job training is, in the long run, less costly. D) Generalists will outdo specialists in management.Passage 5The train clattered over points and passed through a station.Then it began suddenly to slow down, presumably in obedience to a signal. For some minutes it crawled along, then stopped; presently it began to move forward again. Another up-train passed them, though with less vehemence than the first one. The train gathered speed again. At that moment another train, also on a down-line, swerved inwards towards them, for a moment with almost alarming effect. For a time the two trains ran parallel, now one gaining a little, now the other. Mrs. McGillicuddy looked from her window through the windows of the parallel carriages. Most of the blinds were down, but occasionally the occupants of the carriages were visible. The other train was not very full and there were many empty carriages.At the moment when the two trains gave the illusion of being stationary, a blind in one of the carriages flew up with a snap. Mrs. McGillicuddy looked into the lighted first-class carriage that was only a few feet away.Then she drew her breath in with a gasp and half-rose to her feet.Standing with his back to the window and to her was a man. His hands were round the throat of a woman who faced him, and he was slowly, remorselessly, strangling her. Her eyes were starting from their sockets, her face was purple. As Mrs. McGillicuddy watched, fascinated, theend came; the body went limp and crumpled in the man’s hands.At the same moment, Mrs. McGillicuddy’s train slowed down again and the other began to gain speed. It passed forward and a moment or two later it had vanished from sight.Almost automatically Mrs. McGillicuddy’s hand went up to the communication cord, then paused, irresolute. After all, what use would it be ringing the cord of the train in which she was travelling? The horror of what she had seen at such close quarters, and the unusual circumstances, made her feel paralysed. Some immediate action was necessary — but what?The door of her compartment was drawn back and a ticket collector said, “Ticket, please.”51. When Mrs. McGuillicuddy’s train passed through a station, it ________.A. gained speed suddenlyB. kept its usual speedC. changed its speedD. stopped immediately52. Mrs. McGuillicuddy seems to be a (an) ___ person.A. observantB. interestedC. noisyD. nervous53. What did Mrs. McGuillicuddy happen to witness?A. A quarrelB. A murderC. An intimate sceneD. A fight54.

Unit 3 exercises1 The polymerization rate may be experimentally followed by measuring the changes in any of several properties of the system such as density, refraction index, viscosity, or light absorption. Density measurements are among the most accurate and sensitive of the techniques. The density increases by 20-25 percent on polymerization for many monomers. In actual practice the volume of the polymerizing system is measured by carrying out the reaction in a dilatometer. This specially constructed vessel with a capillary tube which allows a highly accurate measurement of small volume changes. It is not uncommon to be able to detect a few hundredths of a percent polymerization by the dilatometer technique.聚合速率可以通过测量体系一些性质的变化进行试验跟踪。

To Hemingway, man's greatest achievement is to show grace under pressure, or what he described in The Sun Also Rises as holding the "purity of line through the maximum of exposure." “grace under pressure”is a repeated theme in his novels. For him, in a world which is crazy and meaningless, there is nothing one can do but to take care of himself and be tough against fate and tough with grace under pressure.His works have sometimes been read as an essentially negative commentary on a modern world filled with sterility, failure, and death. Yet such a nihilistic vision is repeatedly modified by Hemingway's affirmative assertion of the possibility of living with style and courage. His primary concern was an individual's "moment of truth," and his fascination with the threat of physical emotional, or psychic death is reflected in his lifelong preoccupation with stories of war (A Farewell to Arms, 1929, and For Whom the Bell Tolls, 1940), the bullfight (Death in the Afternoon, 1932), and the hunt (The Green Hills of Africa, 1935).Language: (10分)∙For his novels and for his short stories, which include some of the finest in the English language, Hemingway received wide acclaim.
