单选题Future scientific discoveries will make possible the further prolongation of the human life ______.(2008年北京航空航天大学考博试题)

单选题The natural environment still manages to fill us with a sense of awe and amazement. Despite the amount of scientific knowledge mankind has gathered, nature still holds great mysteries that we may never be able to unravel. This complexity has continually daunted man.(66)______ As a result, we have distanced ourselves from the earth, even though our survival is completely dependent on it. We are now trying to regain our close connection to nature. (67)______Referred to as "natural architecture", it aims to create a new, more harmonious, relationship between man and nature by exploring what it means to design with nature in mind. The roots of this movement can be found in earlier artistic shifts like the "land art" movement of the late nineteen sixties. Although this movement was focused on protesting the austerity of the gallery and the commercialization of art, it managed to expand the formal link between art and nature. (68)______ The movement is characterized the work of a number of artists, designers and architects that express these principles in their work. The pieces are simple, humble and built using the most basic materials and skills. (69)______The forms are stripped down to their essence, expressing the natural beauty inherent in the materials and location. The movement has many forms of expression that range from location-based interventions to structures built from living materials. However, all of the works in the movement share a central distinctive spirit that demonstrates a respect and appreciation for nature. These works are meant to comment on architecture and provide a new framework to approach buildings and structures. They aim to infuse new ideas into architecture by subverting the idea that architecture should shelter nature. (70)______We see the branches, the rocks and all the materials for what they are. We understand that these structures won't exist forever. The materials will evolve over time, slowly decomposing until no evidence remains. These features are intentional, provoking viewers to question the convention of architecture. The designers aren't suggesting that architecture must conform to their vision, they are just providing ideas that they hope will inspire us all to rethink the relationship between nature and the built environment. A. This has helped develop a new appreciation of nature in all forms of art and design. B. Instead, the structures deliberately expose the natural materials used in the building process. C. The core concept of the movement is that mankind can live harmoniously with nature, changing and using it for our needs D. There is an emerging art movement that is exploring mankind's desire to reconnect to the earth, through the built environment. E. Because of this, the results often resemble native architecture, reflecting the desire to return to a less technological world. F. In frustration, we try to control nature by enforcing order.

When an invention is made, the inventor has three possible{{U}} (41) {{/U}}of action open to him: he can give the invention to the world by publishing it, keep the idea{{U}} (42) {{/U}}, or patent it. A{{U}} (43) {{/U}}patent is the result of a bargain{{U}} (44) {{/U}}between an inventor and the state, but the inventor gets a limited period of monopoly and publishes full details of his invention to the public after that period{{U}} (45) {{/U}}.

Because a patent remains permanently{{U}} (50) {{/U}}after it has terminated, the shelves of the library attached to the{{U}} (51) {{/U}}office contain details of literally millions of ideas that are free for anyone to use and, if{{U}} (52) {{/U}}than half a century, sometimes even re-patent. Indeed, patent experts often advise anyone{{U}} (53) {{/U}}to avoid the high cost of conducting a search through{{U}} (54) {{/U}}patents that the one sure way of violation of any other inventor's right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form{{U}} (55) {{/U}}invalidates further patents on that idea, it is traditionally{{U}} (56) {{/U}}to take ideas from other areas of print.

单选题Twins often show great ______, but these twins are an exception.

单选题The idea that it is the business of governments to cheer up their citizens has moved in recent years to centre-stage. Academics interested in measures of GDH (gross domestic happiness) were once forced to turn to the esoteric example of Bhutan. Now Britain's Conservative-led government is compiling a national happiness index, and Nicolas Sarkozy, France's president, wants to replace the traditional GDP count with a measure that takes in subjective happiness levels and environmental sustainability. Martin Seligman, a former president of the American Psychological Association, would approve. He has uncovered various structured ways of perking people up, all of them, he insists on the very first page of his new book, "grounded in careful science". Much of this book consists of the results of various complex tests and interventions designed to reduce depression and anxiety and increase resilience and self-discipline. Writing a "what-went-well-today-and-why" diary for a week, for example, tends to lower depression levels for as much as six months, he claims. "Flourish" represents a partial rejection of Mr. Seligman's previous work, "Authentic Happiness" (a title he says was forced on him by his publisher). To focus solely on happiness rather than the more expansive concept of "well-being", Mr. Seligman now says, is a form of "monism" that neglects important ingredients, such as "relationships" and "accomplishment". Research consistently shows that parents are less satisfied with their lives than the childless. Yet the human race continues to propagate itself. Either, says Mr. Seligman, we are "massively deluded" about the effects of children on our happiness, or we take more than "life satisfaction" into account when choosing to breed. Mr. Seligman's book is, in effect, an attempt to add dashes of both Aristotelian wisdom and Nietzschean grit to the stock of Benthamite utilitarianism that underlies much of the newer work in this field. Mr. Seligman says he now rejects the Aristotelian view that all human action aims at happiness. But Aristotle's term, eudaimonia, usually rendered in English as "happiness", actually translates better as "flourishing". Moreover, Mr. Seligman's emphasis on "good character" is reminiscent of the Aristotelian virtues. As for Nietzsche, whose ironic writings seem to occupy another universe from Mr. Seligman's empirically grounded "positive psychology", his idea that the "will to power" drives much human action finds ready approval here. Mr. Seligman has fans. Schools and universities around the world are using his work to craft happier, more robust students. A test designed by Mr. Seligman and his colleagues to assess the psychological fitness of serving troops will, he says, be taken by all American soldiers every year. The many critics of positive psychology are unlikely to be swayed by this book, particularly given its tone, by turns cheesy and hubristic, and its sloppy editing. But they appear to be losing the argument.

单选题Naturally, in a group of animals as diverse as the snakes, and with so many varied enemies, there are numerous defensive reactions and devices. There is, however, one general pattern of hehaviour, in the presence of a suspected enemy the first reaction is to try to escape observation; if this fails, the next resort is flight to some inaccessible retreat, but if this is not possible, or is circumvented, various kinds of intimidatory gestures and warning devices arc brought into play ;in the last resort the snake attacks. This pattern varies with the circumstances; some stages may be omitted or combined unpredictably whilst some notoriously irascible species may dispense with all the preliminaries and attack almost at once, though seldom or never without some provocation. The difficulty is to know what constitutes provocation, a matter that is apt to be debatable in other fields! Amongst the factors that increase aggressiveness are hunger, the mating season and surprise, with the last mentioned the commonest ; when hunting for food or for mates, activity and the aggressive instinct are both at their peak, but it is when it is caught unawares that the normal chain of re- actions tends to become telescoped. Owing to their poor sense of hearing, snakes are very liable to be, quite literally, caught napping and a similar situation arises during their periods of temporary blindness just before sloughing begins. By far the greatest number of snake-bite accidents result from the unwitting disturbance of resting snakes, and this hazard is much increased with species that are well camouflaged and whose natural instinct is to trust to this concealment as their principal defence. As well as differences in aggressiveness between individuals of the same species according to the circumstances and conditions, there are also notable differences between species ,even closely allied species; and the reports of those who have been attacked may understandably be lacking in objectivity. So it is impossible to forecast, even in outline, how any encounter will develop. The Hamadryad, for example,is usually credited with being amongst the most aggressive of snakes ,and there are many accounts of unprovoked attacks ;yet on one occasion fourteen men and seven dogs passed and returned within two yards of a nest and no snake was seen although the fe- male, which guards the nest, could not have been far. away. One very well-known student of snakes once parked his car under some trees near Nairobi and on his return found a small green snake on it. Being preoccupied at the moment he gave it only a cursory glance and, thinking it was a common harmless tree-snake, bundled it unceremoniously into his pocket ;it was, as he later discovered to his horror, a young Green Mamba, but it made no attempt to bite despite the rough treatment it had received. The proportion of the snakes of the world that have some forms of procrypsis( i. e. resemblance to the background)is very high, but the frequency with which the resemblance results in accidents suggests that it is incorrect to regard it as primarily a "protective" device. There is every advantage to a predatory animal in being unobserved until its prey comes within striking distance, but it is distinctly hazardous to allow an enemy to approach closely with the hope ,but no certainty, of remaining undetected. The commonest type of proerypsis is the result of colours that harmonize with hose of the normal background, associated with patterns that disrupt the animal' s outline or produce "counter shading" whereby those parts of the body that will be seen in shadow and appear dark, are lighter in colour whilst highlight areas are dark-coloured.
