单选题Most gulls don"t bother to learn more than the simplest facts of flights how to get from shore to food and back again. For most gulls, it is not flying that matter, but eating. For this gull, though, it was not eating that mattered, but flight: More than anything else, Jonathan Livingston Seagull loved to fly. This kind of thinking, he found, is not the way to make oneself popular with other birds. Even his parents were dismayed as Jonathan spent whole days alone, making hundreds of low-level glides, experimenting. "Why, Jon, why?" his mother asked. "Why is it so hard to be like the rest of the flock, Jon? Why can"t you leave low flying to the pelicans (鹈鹕), the albatross (信天翁)? Why don"t you eat? Son, you"re bone and feathers!" "I don"t mind being bone and feathers, mom. I just want to know what I can do in the air and what I can"t, that"s all. I just want to know." "See here, Jonathan," said his father, not unkindly. "Winter isn"t far away. Boats will be few, and surface fish will be swimming deep. If you must study, —then study food, and how to get it. This flying business is all very well, but you can"t eat a glide. You know. Don"t you forget that the reasons you fly is to eat. " Jonathan nodded obediently. For the next few days he tried to behave like the other gulls: he really tried, screeching and fighting with the flock around the piers(码头) and fishing boats, diving on scraps of fish and bread. But he couldn"t make it work. It"s all so pointless, he thought, deliberately, dropping a hard-won anchovy (鳀类鱼) to a hungry old gull chasing him. "I could be spending all this time learning to fly. There"s so much to learn!" ... "Why aren"t there more of us here? Why, where I came from there were..." "...thousands and thousands of gulls. I know." Sullivan shook his head. "The only answer I can see, Jonathan, is that you are pretty well a one-in-a-million bird. Most of us came along ever so slowly. We went from one world into another that was almost exactly like it, forgetting right away where we had come from not caring where we were headed, living for the moment. Do you have any idea how many lives we must have gone through before we even got the first idea that there is more to life than eating, or fighting, or power in the flock? A thousand lives, Jon, ten thousand! And then another hundred lives until we began to learn that there is such a thing as perfection, and another hundred again to get the idea that our purpose for living is to find that perfection and show it forth "

单选题Psychologically there are two dangers to be guarded against in old age. One of these is undue absorption in the past. It does not do to live in memories, in regrets for the good old days, or in sadness about friends who are dead. One"s thoughts must be directed to the future, and to things about which there is something to be done. This is not always easy; one"s own past is a gradually increasing weight. It is easy to think to oneself that one"s emotions used to be more vivid than they are and one"s mind more keen. If this is true it should be forgotten, and if it is forgotten it will probably not be true. The other thing to be avoided is clinging to youth in the hope of sucking vigor from its vitality. When your children are grown up they want to live their own lives, and if you continue to be as interested in them as you were when they were young, you are likely to become a burden to them, unless they are unusually callous. I do not mean that one should be without interest in them, but one"s interest should be contemplative and, if possible, philanthropic, but not unduly emotional. Animals become indifferent to their young as soon as their young can look after themselves, but human beings, owing to the length of infancy, find this difficult. I think that a successful old age is easiest for those who have strong impersonal interest involving appropriate activities. It is in this sphere that long experience is really fruitful, and it is in this sphere that the wisdom born of experience can be exercised without being oppressive. It is no use telling grownup children not to make mistakes, both because they will not believe you, and because mistakes are an essential part of education. And you must realize that you must not expect that they will enjoy your company. Some old people are oppressed by the fear of death. But I think for an old man who has known human joys and sorrows, and has achieved whatever work it was in him to do, the fear of death is somewhat abject and ignoble. The best way to overcome it—so at least it seems to me—is to make your interest gradually more impersonal, until bit by bit the wails of the ego recede, and your life becomes increasingly merged in the universal life. An individual human existence should be like river—small at first, gradually grows, wider, and in the end, without any visible break, they become merged in the sea, and painlessly lose their individual being. The man who in old age can see his life in this way, will not suffer from the fear of death, since the things he cares for will continue. And if, with the decay of vitality, weariness increases, the thought of rest will not be unwelcome. I should wish to die while still at work, knowing that others will carry on what I can no longer do and content in the thought that what was possible has been done.

单选题What is the charm of necklaces? Why would anyone put something extra around her neck and then invest it with special significance? A necklace doesn"t afford warmth in cold weather, like a scarf, or protection in combat, like chain mail; it only decorates. We might say it borrows meaningfrom what it surrounds and sets off; the head with its supremely important material contents, and the face, that register of the soul. When photograph reduces the reality it represents, they mention not only the passage from three dimensions to two, but also the selection of a point du vue favors the top of the body rather than the bottom and the front rather than the back. The face is the jewel in the crown oi the body, and so we give it a setting. When people are intensely concerned with something that is obviously impractical, anthropologists take note, for lovely useless things often express archaic to exist in contemporary American houses already heated by gas and electricity, yet most people want one and it is still the focus of the living room. This desire testifies, I think, to the hundreds of thousands of years during which we Homo sapiens huddled around a cave fire. We watch ourselves, rather anxiously, vanish backward down those lone temporary corridors, as my daughter gazes at her infinitely multiplied small self in the mutually opposed mirrors of the beauty salon, and wonders, is it me? Our fireplaces and necklaces and tombstones say it is, they are. In American culture, an interest in necklaces seems to be rather gender specific. Many men to whom I mention the enterprise feign polite interest and then change the subject, though I know some who admire, construct, and wear necklaces, including the distinguished scientist and poet to whom this essay is dedicated. Most women, by contrast, become mildly or wildly enthusiastic. A doctor in Blois brought out her entire collection of costume jewelry for me, exhibited the most splendid pieces with an account of where and when they were purchased, and then explain them all with the help of a large glossy book on the history of costume jewelry , with dozens of pictures. A former student of mine who had moved to California mailed me six plastic boxes full of beads gleaned from a warehouse managed by an eccentric: friend who just their settings; a feature bead painted with a naked lady; crystal roundels of truly exceptional shine; and tiny silver hematite seed beads. Beads lend themselves to exchange, Beads travel. And clearly these two facts are related.

单选题Microsoft and Apple in a Tough New World There is a smug maxim in Silicon Valley arid the places that imitate it: "To survive, you must destroy your company every x years" (where x varies according to how much the speaker wants to stress the pace of technological change). Sometimes attributed to Intel"s former chief executive Andy Grove, it is a maxim more often repeated than observed. But it can be a lovely and startling thing when a large, publicly traded company takes a big bet by replacing its core product. Microsoft"s new Windows 8 operating system, which went on sale last Friday, is the most dramatic gamble by a technology company since Intel abandoned the memory market to make semiconductors in the 1980s. Windows is a civilisational tool; there are more than 1bn Windows users around the world but when, after being given a new personal computer by their IT manager or buying a new device for themselves, those users boot up the new OS, they will recognise nothing. Gone is the familiar "Start" button and user interface Microsoft has used since it launched Windows 95, 17 years ago. In its place, users will find a screen of shifting colourful tiles. If they have set up a Microsoft account with Outlook, their email, calendar and contacts will appear automatically; if their Microsoft account is linked to Facebook, the faces of their Facebook friends will begin blinking in a People tile and the photos they have posted will float into a Live tile. To its new users, Windows 8 will seem as personal—and as non-corporate—as their smartphone or tablet computers. That is the whole idea. Windows 8 can be used with a conventional personal computer with a mouse or touchpad, but doing so is confusing. The operating system works best with a touch screen, where users can swipe tiles and icons. To show off the new functionality, Microsoft is selling its first computer, the Surface—a $499 touch screen tablet whose cover is a small keyboard, so that the device can also function as a small laptop. Windows 8 and Surface are elegant and innovative, not qualities one associates with Microsoft"s products. They are mostly the work of Steven Sinofsky, president of the company"s Windows division, who keeps a much-read blog at MSDN, the Microsoft developer network. There, defending the radical change in the design, he wrote: "The new Windows 8 user experience is no less than a bet on the future of computing, and stakes a claim to Windows" role in that future. " Last week the crush at Microsoft"s Times Square store reminded some of the crowds at the launch of an Apple product—which must have been Microsoft"s hope. But Mr. Sinofsky"s bet also has the logic of desperation. A decade ago there were no competitors to Microsoft"s core business of developing and selling "platforms", the software upon which other developers" software must run and with which hardware must work. Today, the web is the platform for most computing and Apple"s iOS (the operating system of the iPhone and iPad) and Google"s Android are the platforms for mobile devices. The sharp edges between business and consumer computing have melted. Microsoft had no choice but to try something new. It is instructive to compare the launch of Windows 8 and Surface with Apple"s most recent release, the iPad mini. There"s nothing wrong with the mini : for Tim Cook, Apple"s chief executive, it must seem to fill an important niche—the market for tablets that can be held comfortably in one hand, where Amazon"s Kindle and devices based on Android now dominate. But there"s nothing innovative about Apple"s small tablet. It"s just more of the same. One cannot imagine the late Steve Jobs, Apple"s departed CEO, taking any pride in the thing. It is an interesting historical moment for the two founding companies of the personal computing revolution. Microsoft knows it is slowly dying but declines to accept its fate. Apple, flush with cash, does not yet have to admit that with the death of its tutelary genius, it has lost its way. But secretly, its executives, designers and developers must fear that something is badly wrong. Jobs always said that technology companies began to die when salespeople and bean counters started making the decisions.
