We can see why benzene is stable: according to resonance theory, the more resonance forms a substance has, the more stable it is. Benzene, with two resonance forms of equal energy, is therefore more stable and less reactive than a typical alkene.2. Membranes can be defined essentially as barrier, which separates two phases and restricts transport of various chemicals in a selective manner. A membrane can be homogenous or heterogeneous, symmetric or asymmetric in structure, solid or liquid, can carry a positive or negative charge or be neutral or bipolar. Transport through a membrane can be effected by convection or by diffusion of individual molecules, induced by an electric field or concentration, pressure or temperature gradient. The membrane thickness may vary from as small as 100 micron to several mms.3. The most common industrial adsorbents are activated carbon, silica gel, and alumina, because they present enormous surface areas per unit weight.A surface already heavily contaminated by adsorbates is not likely to have much capacity for additional binding, but further heating will drive off these compounds to produce a surface with high adsorptive capacity.Temperature effects on adsorption are profound, and measurements are usually at a constant temperature. Graphs of the data are called isotherms. Most steps using adsorbents have little variation in temperature.A卷【第2页共 3 页】4. In the absence of peroxides, hydrogen bromide adds to peopene via the Markovnikov pathway to yield isopropyl bromide. In the presence of peroxides, however, the order of addition is reversed, and the product is n-propyl bromide; the addition in this case is said to be anti-Markovnikov. This is interpreted in terms of initiation of the addition reaction by bromine atom, rather than by a proton, as is the case for electrophilic addition.四、Translate the following paragraphs into Chinese（20 points）1．Benzene and its derivatives can be nitrated using a mixture of concentrated nitric and sulphuric acid. The temperature must be controlled to prevent more than one nitro-group going in.2. Benzene can be made to react with halogen derivatives using aluminium chloride as a catalyst. This is called a Friedel-Crafts reaction.can be sulphonated by reacting it with fuming sulphuric acid(oleum). The benzene reacts with sulphur trioxide in the oleum.benzene is converted into ethylbenzene by reacting it with ethene. The ethylbenzene (also called styrene) is used to make polystyrene.黄冈师范学院2009—2010学年度第一学期期末试卷参考答案及评分标准考试课程：专业英语考核类型：考试A卷考试形式：闭卷出卷教师：杨一思考试专业：化学考试班级：应用化学200601 一、Translate the following into English（20 points）2. concentrate 4. adsorption chlorideequilibriumtensionconstant14. propylmagneticresonanceentropy二、Translate the following into Chinese（20 points）1. 丙酸甲酯2. 速率常数3. 甲乙酮4. 自有能5. 自由基中间体6. 异丁基甲醚7. 3-氯丙烯8. 伯自由基9. 正丙基溴化10. 键能11.循环电子12. 局部电磁场13. 四甲基硅烷14. 质荷比15.苯胺16.氨基化合物17.胺18亲核试剂19.高氯酸盐20.碳正离子三、Translation the following into chinese （50 points）1．依据共振理论，物质具有的共振式越多就越稳定。

浙江大学应用化学专业大一《综合英语四》考试A卷及答案

综合英语四考试试卷适用于考试日期：试卷所需时间：120分钟闭卷；A 卷；试卷总分：100分。

Part I Reading Comprehension 40%Directions: There are 4 passages in this section. Each passage is followed by somequestions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice. Please write the answer on the Answer Sheet .Passage 1Three passions, simple but overwhelmingly strong, have governed my life: thelonging for love, the search for knowledge, and the unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a deep ocean of anguish, reaching to the very verge of despair.I have sought love, first, because it brings ecstasy -- ecstasy so great that I would often have sacrificed all the rest of life for a few hours of this joy. I have sought it, next, because it relieves loneliness -- that terrible loneliness in which one shivering consciousness looks over the rim of the world into the cold unfathomable lifeless abyss. I have sought it, finally, because in the union of love I have seen, in a mystic miniature, the prefiguring vision of the heaven that saints and poets have imagined. This is what I sought, and though it might seem too good for human life, this is what -- at least -- I have found. With equal passion I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. And I have tried to apprehend the Pythagorean power by which number holds sway above the flux. A little of this, but not much, I have achieved.Love and knowledge, so far as they were possible, led upward toward the heavens. But always pity brought me back to earth. Echoes of cries of pain reverberate in my heart. Children in famine, victims tortured by oppressors, helpless old people a hated burden to their sons, and the whole world of loneliness, poverty, and pain make a mockery of what human life should be. I long to alleviate the evil, but I can ’t, and I too suffer.This has been my life. I have found it worth living, and would gladly live it again if the chance were offered me.1. What rhetorical device does the author use in the first paragraph? A) Hyperbole and simile. B) personification and hyperbole. C) parallelism, simile and metaphor. D) All of the above.2. For how many reasons has the author sought love?A) 1. B) 2. C) 3. D) 4.3. The reason why the author mentions Pythagorean power is ____________ A) to substantiate his viewpoint B) that he is a mathematicianC) to show his talent in mathematicsD) that this essay is based on Pythagorean theory 4. Why does the author say he suffers too? A) Because he is homeless. B) Because he is ill.C) Because he cannot alleviate all the evil that he hates.D) Because he does not have enough money to support the poor. 5. What is the basic tone for the whole passage?A) Critical. B) Ironic. C) Pathetic. D) Passionate. Passage 2Since Tiger was so fortunate with the game of golf, he decided to start a foundation called: The Tiger Woods Foundation which starts schools in urban American cities that provided an education for less fortunate kids. Tiger also supports and donates money to The First Tee program. The First Tee program’s goal is to provide learning facilities and educational programs that promote character development and life enhancing values through the game of golf. Tiger himself has also been an idol or hero for many kids around the world because of his dominance and records throughout his golfing career. Because of this many kids have started learning the game of golf.Tiger ’s real first name is Eldrick. He was born on December 30, 1975 and grew up in Cypress California. He began taking an interest in golf when he was just six months old. He would watch his dad, Earl, hit golf balls into a net and would try to copy his swing. He was given the nickname Tiger after a Vietnamese soldier and friend of his father. Tiger Woods appeared on TV practicing his swing at the age of two and by the time he was three, he had already shot a 48 on a nine-hole course. When he was five, the golf world began to take notice of Tiger and he was featured on the cover of Golf Digest. Tiger Woods was just 16 and still in high school when he played in his first professional golf tournament - the Nissan Los Angeles Open. Two years later, he went to college at Stanford University where he won ten collegiate events and the NCAA (National Collegiate Athletic Association) title. While he appeared in only a handful of professional tournaments during his years in college, it wasn’t long before Tiger Woods would be winning pro events at a ridiculous rate.Tiger Woods, who is now 28 years old, has had an amazing career since becoming a pro golfer in 1996. He has won 53 worldwide tournaments, 40 of those wins were on the PGA TOUR, including eight major championships: the 1997, 2001, and 2002 Masters, the 1999 and 2000 PGA Championships, the 2000 and 2002 U.S. Open Championship and the 2000 British Open. Tiger has now won an incredible 9 out of 16 World Golf Championship events he has played in.Tiger relates to the book because he is a hero to others near and far. People around the world notice his dedication, time spent working to perfect his game, his fitness routines and since he is young, all the kids like that. Even if you didn’t play golf, you would know who Tiger is and he has influenced many people to take up the game and learn more than just how to play: to learn the integrity and rules which also help you in life.To wrap things up, Tiger Woods started the game at a young age and set many records that may never be broken and has changed the game forever. He’s a hero, incredible golfer, and a generous giving man. He works hard at everything he does and gives back whenever he can. That is why I chose Tiger to be my hero.院系：班级：姓名：学号：装订线6.

What might be the best title for the passage?A) Tiger Woods B) The world’s Best GolferC) The Brightest Sports Star D) Sports Hero: Tiger WoodsPassage 340 years ago the idea of disabled people doing sport was never heard of. But when the annual games for the disabled were started at Stoke Mandeville, England in 1948 by Sir Ludwing Guttmann, the situation began to change.Sir Ludwing Guttmann, who had been driven to England in 1939 from Nazi Germany, had been asked by the British government to set up an injuries center at Stoke Mandeville Hospital near London. His ideas about treating injuries included sport for the disabled.In the first games just two teams of injured soldiers took part. The next year, 1949, five teams took part. From those beginnings, things have developed fast. Teams now come from abroad to Stoke Mandeville every year. In 1960 the first Olympics for the Disabled were held in Rome. Now, every four years the Olympic Games for the Disabled are held, if possible, in the same place as the normal Olympic Games although they are organized separately. In other years Games for the Disabled are still held at Stoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about 40 countries took part. Unfortunately, they were held at Stoke Mandeville and not in Los Angeles, along with other Olympics.The Games have been a great success in promoting international friendship and understanding, and in proving that being disabled does not mean you can’t enjoy sport. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include disabled events at the Olympic Games for the able-bodied.Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athletes should not be excluded.11. The first games for the disabled were held _______ after Sir Ludwing Guttmannarrived in England.A) 40 years B) 21 yearsC) 10 years D) 9 years12. Besides Stoke Mandeville, surely the games for the disabled were once held in_______.A) New York B) LondonC) Rome D) Los Angeles13. In Paragraph 3, the word “athletes” means _______.A) people who support the games B) people who watch the gamesC) people who organize the games D) people who compete in the games14. Which of the following statements is NOT true?A) Sir Ludwing Guttmann is an early organizer of the games for the disabled.B) Sir ludwing Guttmann is an injured soldier.C) Sir Ludwing Guttmann is from Germany.D) Sir Ludwing Guttmann is welcomed by the British government.15. From the passage, we may conclude that the writer is _______.A) one of the organizers of the games for the disabledB) a disabled person who once took part in the gamesC) against holding the games for the disabledD) in favor of holding the games for the disabledPassage 4Books are to mankind what memory is to the individual. They contain the history of our race, the discoveries we have made, the accumulated knowledge and experience of ages. They picture for us the marvels and beauties of nature, help us in our difficulties, comfort us in sorrow and in suffering, change hours of weariness into moments of delight, store our minds with ideas, fill them with good and happy thoughts, and lift us out of and above ourselves.Many of those who have had, as we say, all that this world can give, have yet told us they owed much of their purest happiness to books. Aseham, in “The Schoolmaster,” tells a touching story of his last visit to Lady Jane Grey. He found her sitting in an oriel window reading Plato’s beautiful account of the death of Socrates. Her father and mother were hunting in the park. The hounds were in full cry and their voices came in through the open window. He expressed his surprise that she had not joined them. But, said she, “I wish that all their pleasure in the park is but a shadow to the pleasure I find in Plato.”Macaulay had wealth and fame, rank and power, and yet he tells us in his biography that he owed the happiest hours of his life to books. In a charming letter to a little girl, he says: “Thank you for your very pretty letter. I am always glad to make my little girl happy, and nothing pleases me so much as to see that she likes books, for when she is as old as I am, she will find that they are better than all the tarts and cakes, toys and plays, and sights in the world. If any one would make me the greatest king that ever lived, with palaces and gardens and fine dinners, and wines and coaches, and beautiful clothes, and hundreds of servants, on condition that I should not read books, I would not be a king. I would rather be a poor man in a garret with plenty of books than a king who did not love reading.”Books, indeed, endow us with a whole enchanted palace of thoughts. “There is a wider prospect,” says Jean Paul Richter, “from Parnassus than from a throne.” In one way they give us an even more vivid idea than the actual reality, just as reflections are often more beautiful than real nature. “All are mirrors,”says George Macdonald. “The commonest room is a room in a poem when I look in the glass.”Precious and priceless are the blessings which the books scatter around our daily paths. We walk, in imagination, with the noblest spirits, through the most sublime and enchanting regions.16.

Similarly, the phosphate ion, PO43-, needs these H+ ions, so its parent acid is the molecular compound H3PO4, phosphoric acid.
In such cases, the ion with the larger number of oxygen atoms is given the suffix –ate, and that with the smaller number of oxygen atoms is given the suffix –ite. Thus, NO2- is nitrate and NO3- is nitrite. 在这种情况下，含氧原子数较多的离子加以后缀-ate，反之加以后缀-ite。因此，NO3-为硝酸盐，为NO2-亚硝酸盐。
Monatomic anions are named by adding the suffix –ide and the word ion to the first part of the name of the element ( the “stem” of its name ). 单原子阴离子通过在元素名字（名字的词干）的第一部分加后缀-ide和离子单词来命名。
The names of oxoanions are formed by adding the suffix –ate to the stem of the name of the element that is not oxygen, as in the carbonate ion, CO32-. 含氧阴离子的名字是在非氧元素的词干后加后缀-ate形成，如碳酸盐，CO32-。

Answer: The scientific method is a logical and systematic approach to problem solving in science. It consists of several key steps including observation, hypotheses,experimentation, and theory. Scientists use the scientific method to answer questions and solve problems by gathering data through observation and experimentation, forming hypotheses based on that data, testing those hypotheses through experimentation, andfinally developing theories to expln the results of those experiments.2.Describe the properties of matter and how they are used to differentiate between substances. Answer: Properties of matter can be either physical or chemical. Physical properties include mass, volume, density, color, melting point, boiling point, and solubility. These properties can be used to differentiate between substances by comparing their physical properties. Chemical properties include reactivity, flammability, and toxicity. These properties are used to differentiate between substances based on their chemical behavior under certn conditions.3.Describe the structure of an atom and the role that subatomic particles play in determining chemical behavior. Answer: Atoms have a central nucleus that contns protons and neutrons. Electrons orbit around the nucleus in shells or orbitals. Protons carry a positive charge, electrons carry a negative charge, and neutrons carry no charge. The number of protons in the nucleus determines the element to which the atom belongs, while the number of electrons in the outermost shell determines the chemical behavior of the atom.4.Expln the difference between a mixture and a pure substance. Give examples of each. Answer: A mixture is a combination of two or more substances that are not chemically bonded together. Mixtures can be either homogeneous or heterogeneous. A homogeneous mixture is a uniform mixture where the composition is the same throughout, such as saltwater. A heterogeneous mixture is a non-uniform mixture where the composition varies, such as oil and water. A pure substance is a substance that cannot be broken down into simpler substances by chemical means. Examples of pure substances include elements such as gold and silver, and compounds such as water and carbon dioxide.5.Expln the difference between a physical change and a chemical change. Give examples of each. Answer: A physical change is a change in the physical properties of a substance, such as shape, size, or state of matter, without changing its chemical composition. Examples of physical changes include melting ice, boiling water, and cutting paper. A chemical change is a change in the chemical properties or composition of a substance, resulting in the formation of a new substance or substances. Examples of chemical changes include burning of wood, digestion of food, and rusting of iron.。
