单选题He is a rare celebrity scientist. He's even had a TV cameo role (小角色) in Star Trek in which he plays poker with scientific icons (偶像)Sir Isaac Newton and Albert Einstein. Yet when asked about comparisons between himself and the two scientists, he calls it all "media hype (炒作)." Once asked how he felt about being labeled the world's smartest person, he responded: "It is very embarrassing. It is rubbish, just media hype. They just want a hero, and I fill the role model of a disabled genius. At least I am disabled, but I am no genius. " Hawking has ALS or Lou Gehrig's disease, a neuromuscular disease that progressively weakens muscle control. He gets around in a wheelchair, and after completely losing the use of his vocal chords in an operation to assist his breathing in 1985, he communicates through a computer. A speech synthesizer "speaks" for him after he punches in what he wants to say, selecting words in the computer software by pressing a switch with his hand. Unfortunately, it makes him sound like he has an American accent, he says. Despite his humorous, self-effacing manner, Hawking is one of the world's leading theoretical physicists. Many consider him to be the most brilliant since Einstein. Since 1979, he's held the post of Lucasian professor of mathematics at Cambridge University—which was once held by Isaac Newton no less—and has twelve honorary degrees. He's also a best-selling author. His book, A Brief History of Time ,has been translated into 33 languages and has sold nine million copies. For much of his academic life, Hawking has been among a group of theoretical physicists searching for a "theory of everything'—one unified scientific theory that explains the big cosmological questions like How did the universe begin? Why is the universe the way it is? and How will it end ? You are probably familiar with the existing theories, such as the Big Bang theory. However, these theories are inconsistent with each other. So Hawking—among a group of theoretical physicists—has been on a quest to come. up with a theory of quantum (量子)gravity that would incorporate these theories—the theory of everything (TOE)—which would solve the problem of what caused the universe to start expanding. How successful have the world's leading cosmologists been? Hawking predicts we'll have the TOE in the next 20 years.

单选题{{B}}Passage Five{{/B}} Complaining about faulty goods or bad service is never easy. Most people dislike making a fuss. But if something you have bought is faulty or does not do what was claimed for it, you are not asking for a favour to get it put right. It is the shopkeeper's responsibility to take the complaint seriously and to replace or repair a faulty article or put right poor service, because he is the person with whom you have entered into an agreement. The manufacturer may have a part to play but that comes later. Complaints should be made to a responsible person. Go back to the shop where you bought the goods, taking with you any receipt you may have. Ask to see the owner in a large store. In a small store the assistant may also be the owner so you can complain directly. In a chain store ask to see the manager. If you telephone, ask the name of the person who handles your enquiry, otherwise you may never find out who dealt with the complaint later. Even the bravest person finds it difficult to stand up in a group of people to complain, so if you do not want to do it in person, write a letter. Stick to the facts and keep a copy of what you write. At this stage you should give any receipt numbers, but you should not need to give receipts or other papers to prove you bought the article. If you are not satisfied with the answer you get, or if you do not get a reply, write to the managing director of the firm, shop, or organization. Be sure to keep copies of your own letters and any you receive. If your complaint is a just one, the shopkeeper may offer to replace or repair the faulty article. You may find this an attractive solution. In certain cases you may have the right to refuse the goods and ask for your money back, but this is only where you have hardly used the goods and have acted at once. Even when you cannot refuse the goods you may be able to get some money back as well. And if you have suffered some special loss, if for example a new washing machine tears your clothes, you might receive money to replace them. If the shopkeeper offers you a credit note to be used to buy goods in the same shops but you would rather have money say so. If you accept a credit note remember that later you will not be able to ask for your money. If the shopkeeper refuses to give you money, ask for advice from your Citizens' Advice Bureau before you accept a credit note. In some cases the shopkeeper does not have to give you your money back -- if, for example, he changes an article simply because you don't like it or it does not fit. He does not have to take back the goods in these circumstances.

单选题It"s generally been said that history is written by the winners. This was never more true than on March 12, when the Texas board of education voted 10-5 in favour of curriculum standards that would promote conservative takes on controversial issues in the pages of the state"s textbooks. The changes, expected to win final approval in May, include an increased emphasis on and sympathetic treatment of such Republican standards as the National Rifle Association and the Moral Majority. They also boast the advantage of capitalism and the role of Christianity in the nation"s founding. Even Thomas Jefferson"s profile will be reduced; some board members were less than fond of his ideas about the division of church and state. This is not Texas" first such skirmish. Since the 1970s, the state has tried to drop books that were seen as too liberal or anti-Christian, to omit passages on the gay-rights movement and to tone down global-warming arguments. But the nation"s battle over textbooks stretches back almost half a century earlier. In 1925, Tennessee"s Butler Act (which was abolished in 1967) made it illegal to teach "any theory that denies the story of the Divine Creation of man as taught in the Bible ." The Scopes "monkey trial" famously followed. In 1974, a clash erupted in Kanawha County, West Virginia, over the controversial writings of such authors as George Orwell, Arthur Miller and Allen Ginsberg. Opposition was so heated that some schools were firebombed. As one of America"s largest textbook buyers, the Longhorn State has a good deal of sway over what is sold to schools nationwide. And while Napoleon may have maintained that "history is the version of past events that people have decided to agree upon," getting Texans to come together on the past may prove to be their Waterloo.

单选题{{B}}Part B{{/B}}Directions: The following paragraphs are given in a wrong order. For questions 41--45, you are required to reorganize these paragraphs into a coherent article by choosing from the list A--G to fill in each numbered box. The first and the last paragraphs have been placed for you in boxes. [A] In our time women have an average lifespan of almost 80 years; double of what it was in the last century. Motherhood can be postponed and in theory marriage can be postponed. Women in the US are studying more than men and they may become main breadwinner in the near future. [B] Many women go through life thinking, consciously or unconsciously, that a man will solve all their problems, "Once we are married, everything will be OK. " This attitude only set us up for failure. Men are not princes ready to take any challenge to rescue the princesses; they are human beings with their own needs and fears. [C] Carrie was wondering in her bedroom about the comment that her friend, New York socialite Charlotte York, made "Women want to be rescued. " Carrie wonders, "Is that true? Is that the only thing women want? Rescued by whom? If the prince did not kiss Snow White, would she have been frozen forever or would she have woken up anyway and moved on?" Snow White probably had no other chance, but we do. [D] No wonder our society has changed. On the other hand, our values have not fast enough and many women, more so Hispanic women, are just waiting to be rescued by the prince. These women have not realized they no longer need to be rescued; they need a man for other reasons, not to take care of them. [E] Women in our society have so many options that we do not need anybody else to rescue us; we are the only ones that can rescue ourselves. If you have areas of your life that you want to improve, go ahead; do it for you and for you only, or accept yourself as you are. Do not be so naive that you think someone else can take care of all your problems. Life does not work like that. Live life to the fullest, be happy with who you are and you will see that if you are happy with yourself, you will make others happy, including your man. [F] Our society has changed in a remarkable way in the last 50 years or so. And there are many reasons for it. At the beginning of the 20th century women's lifespan was about 40 years. Therefore, life needed to start earlier if a woman were going to live for only 40 years; motherhood was a priority. Men used to work and women stayed at home and took care of them and their kids. Women could not survive without a man; women needed to be rescued. [G] Women are caregivers. We are strong and smart and we have the ability to take care of ourselves; we do not need to be rescued by anyone. When we are giving our power to others in exchange for security, we are also giving up our freedom. Are you waiting to be rescued? Do you ever think like that? Order:

单选题An important point in the development of a governmental agency is the codification of its controlling practices. The study of law or jurisprudence is usually concerned with the codes and practices of specific governments, past or present. It is also concerned with certain questions upon which a functional analysis of behavior has some bearing. What is a law? What role does a law play in governmental control? In particular, what effect does it have upon the behavior of the controllee and of the members of the governmental agency itself? A law usually has two important features. In the first place, it specifies behavior. The behavior is usually not described topographically but rather in terms of its effect upon others - the effect that is the object of governmental control. When we are told, for example, that an individual has "committed perjury," we are not told what he has actually said. "Robbery" and "assault" do not refer to specific forms of response. Only properties of behavior which are aversive to others are mentioned - in perjury the lack of a customary correspondence between a verbal response and certain factual circumstances, in robbery the removal of positive reinforces, and in assault the aversive character of physical injury. In the second place, a law specifies or implies a consequence, usually punishment, A law is thus a statement of a contingency of reinforcement maintained by a governmental agency. The contingency may have prevailed as a controlling practice prior to its codification as a law, or it may represent a new practice which goes into effect with the passage of the law. Laws are thus both descriptions of past practices and assurafices of similar practices in the future. A law is a rule of conduct in the sense that it specifies the consequences of certain actions which in mm "rule" behavior. The effect of a law upon the controlling agency The government of a large group requires an elaborate organization, the practices of which may be made more consistent and effective by codification. How codes of law affect governmental agents is the principal subject of jurisprudence. The behavioral processes are complex, although presumably not novel. In order to maintain or "enforce" contingencies of governmental control, an agency must establish the fact that an individual has behaved illegally and must interpret a code to determine the punishment. It must then carry out the punishment. These labors are usually divided among special subdivisions of the agency. The advantages gained when the individual is "not under man but under law" have usually been obvious, and the great codifiers of law occupy places of honor in the history of civilization. Codification does not, however, change the essential nature of governmental action nor remedy all its defects.Comprehension Questions:

单选题Almost every family buys at least one copy of a newspaper every day. Some people subscribe to as many as two or three different newspapers. But why do people read newspapers? Five hundred years ago, news of important happenings--battles lost and won, kings or rulers overthrown or killed—took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in faraway countries on the same day they happen. Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and, of course, advertisements. There are all sorts of advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for their advertising space, but it is worth the money, for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit.
