单选题A stout old lady was walking with her basket down the middle of a street in Petrograd to the great confusion of the traffic and with no small peril to herself. It was pointed out to her that the pavement was the place for pedestrians, but she replied; "I'm going to walk where I like. We've got liberty now. " It did not occur to the dear old lady that if liberty entitled the pedestrian to walk down the middle of the road, then the end of such liberty would be universal chaos. Everybody would be getting in everybody else's way and nobody would get anywhere. Individual liberty would have become social anarchy. There is a danger of the world getting liberty-drunk in these days like the old lady with the basket, and it is just as well to remind ourselves of what the rule of the road means. It means that in order that the liberties of all may be preserved, the liberties of everybody must be curtailed. When the policeman, say, at Piccadilly Circus steps into the middle of the road and puts out his hand, he is the symbol not of tyranny, but of liberty. You may not think so. You may, being in a hurry, and seeing your car pulled up by this insolence of office, feel that your liberty has been outraged. How dare this fellow interfere with your free use of the public highway? Then, if you are a reasonable person, you will reflect that if he did not interfere with you, he would interfere with no one, and the result would be that Piccadilly Circus would be a maelstrom that you would never cross at all. You have submitted to a curtailment of private liberty in order that you may enjoy a social order which makes your liberty a reality. Liberty is not a personal affair only, but a social contract. It is an accommodation of interests. In matters which do not touch anybody else's liberty, of course, I may be as free as I like. If I choose to go down the road in a dressing-gown who shall say me nay? You have liberty to laugh at me, but I have liberty to be indifferent to you. And if I have a fancy for dyeing my hair, or waxing my moustache(which heaven forbid), or wearing an overcoat and sandals, or going to bed late or getting up early, I shall follow my fancy and ask no man's permission. I shall not inquire of you whether I may eat mustard with my mutton. And you will not ask me whether you may follow this religion or that, whether you may prefer Ella Wheeler Wilcox to Wordsworth, or champagne to shandy. In all these and a thousand other details you and I please ourselves and ask no one's leave. We have a whole kingdom, in which we rule alone, can do what we choose, be wise or ridiculous, harsh or easy, conventional or odd. But directly we step out of that kingdom, our personal liberty of action becomes qualified by other people's liberty. I might like to practice on the trombone from midnight till three in the morning. If I went on to the top of Everest to do it, I could please myself, but if I do it in my bedroom my family will object, and if I do it out in the streets then neighbors will remind me that my liberty to blow the trombone must not interfere with their liberty to sleep in quiet. There are a lot of people in the world, and I have to accommodate my liberty to their liberties. We are all liable to forget this, and unfortunately we are much more conscious of the imperfections of others in this respect than of our own. A reasonable consideration for the rights or feelings of others is the foundation of social conduct. It is in the small matters of conduct, in the observance of the rule of the road, that we pass judgment upon ourselves, and declare that we are civilized or uncivilized. The great moments of heroism and sacrifice are rare. It is the little habits of commonplace intercourse that make up the great sum of life and sweeten or make bitter the journey.

单选题Motorola Inc., the world's second-largest mobile phone maker, will begin selling all of the technology needed to build 'a basic mobile phone to outside manufacturers, in a key change of strategy. The inventor of the cell phone, which has been troubled by missteps compounded by a recent industry slump in sales, is trying to become a neutral provider of mobile technology to rivals, with an eye toward fostering a much larger market than it could create itself. The Chicago area-based company, considered to have the widest range of technologies needed to build a phone, said it planned to make available chips, a design layout for the computer board, software, development tools and testing tools. Motorola has previously supplied mobile phone manufacturers with a couple of its chips, but this is the first time the company will offer its entire line of chips as well as a detailed blueprint. Mobile phones contain a variety of chips and components to control power, sound and amplification. Analysts said they liked the new strategy but were cautious about whether Motorola's mobile phone competitors would want to buy the technology from a rival. The company, long known for its top-notch (等级) engineering culture, is hoping to profit from its mobile phone technology now that the basic technology to build a mobile phone has largely become a commodity. Motorola said it will begin offering the technology based on the next-generation GPRS (Global Packet Radio Service) standard because most mobile phone makers already have technology in place for current digital phones. GPRS offers faster access to data through "always on" network connections, and customers are charged only for the information they retrieve, rather than the length of download. Burgess said the new business will not conflict with Motorola's own mobile phone business because the latter will remain competitive by offering advanced features and designs. Motorola's phones have been criticized as being too complicated and expensive to manufacture, but Burgess said Motorola will simplify the technology in the phones by a third. In addition to basic technology, Burgess said, Motorola would also offer additional features such as Bluetooth, a technology that allows wireless communications at a short distance, and Global Positioning System, which tracks the user's whereabouts, and MP3 audio capability.

单选题{{B}}Passage 3{{/B}} Classified Advertising is that advertising which is grouped in certain sections of the paper and is thus distinguished from display advertising. Such groupings as "Help Wanted", "Real Estate", "Lost and Found" are made, the rate charged being less than that for display advertising. Classified advertisements are a convenience to the reader and a saving to the advertiser. The reader who is interested in a particular kind of advertisement finds all advertisements of that type grouped for him. The advertiser may, on this account, use a very small advertisement that would be lost if it were placed among larger advertisements in the paper. It is evident that the reader approaches the classified advertisement in a different frame of mind from that in which he approaches the other advertisements in the paper. He turns to a page of classified advertisements to search for the particular advertisement that will meet his needs. As his attention is voluntary, the advertiser does not need to rely to much extent on display type to get the reader's attention. Formerly all classified advertisements were of the same size and did not have display type. With the increase in the number of such advertisements, however, each advertiser within a certain group is vying with others in the same group for the reader's attention. In many cases the result has been an increase in the size of the space used and the addition of headlines and pictures. In that way the classified advertisement has in reality become a display advertisement. This is particularly true of real-estate advertising.

单选题Parents often faced the ______ between doing what they felt was good for the development of the child and what they could stand by way of undisciplined noise and destructiveness. (2013年北京航空大学考博试题)

单选题To paraphrase 18th-century statesman Edmund Burke, "All that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is tested in animals — no meat, no far, no medicines. Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don't worry, scientists will find some way of using computers." Such well-meaning people just don't understand. Scientists must communicate their message to the public in a compassionate, understandable way — in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother's hip replacement, a father's bypass operation, a baby's vaccinations, and even a pet's shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.

单选题Debbie is a divorcee who lives with her children. She works in a doctor' s office and enjoys the contact with people. Her son, John, age ten, stays with a neighbor both before and after school. Jennifer, her daughter, age five, goes to a day-care center. Debbie' s daily responsibility often seems overwhelming. Each morning she prepares breakfast, fixes bag lunches and organizes things she and the children need to take for the day. Debbie insists her children make their beds before leaving in the morning. Neither child, however, is able to meet her standards, so she usually makes the beds while they are eating. The children watch television and usually are not ready to leave when they should be. Debbie has been late to work several times during the last few months. Debbie feels guilty for not being more a part of her children' s day. John' s teacher recently sent a note home that expressed concern about his behavior. Debbie is often too tired to give the children much attention during the evening.
