填空题The program was televised______ (live) to the whole world.

填空题[A] The impotence of creationism.[B] Natural selection acts by competition.[C] The role of natural selection in this colorful world[D] The delicate hierarchy of the natural system.[E] The agency of selection can account for more cases.[F] No leaps in natural evolution. As each species tends by its geometrical rate of reproduction to increase excessively in number; and as the modified descendants of each species will be enabled to increase by as much as they become more diversified in habits and structure, so as to be able to seize on many and widely different places in natural selection to preserve the most divergent offspring of any one species. Hence, during a long-continued course of modification, the slight differences characteristic of varieties of the same species, tend to be augmented into the greater differences characteristic of the species of the same genus. 41. __________ New and improved varieties will inevitably displace and destroy the older, less improved, and intermediate varieties; and thus species are rendered to a large extent defined and distinct objects. Dominant species belonging to the larger groups within each class tend to give birth to new and dominant forms; so that each large group tends to become still larger, and at the same time more divergent in character. But as all groups cannot thus go on increasing in size, for the world would not hold them, the more dominant groups beat the less dominant. 42. __________ This tendency in the large groups to go on increasing in size and diverging in character, together with the inevitability of much extinction, explains the arrangement of all the forms of life in groups subordinate to groups, all within a few great classes, which has prevailed throughout all time. This grand fact of the grouping of all organic beings under what is called the Natural System, is utterly unexplainable on the theory of creation. 43. __________ As natural selection acts solely by accumulating slight, successive, favorable variations, it can produce no great or sudden modifications; it can act only by short and slow steps. We can see why throughout nature the same general end is gained by an almost infinite diversity of means, for every peculiarity when once acquired in long inherited, and structures already modified in many different ways have to be adapted for the same general purpose. We can, in short, see why nature is extravagant in variety, though not generous in innovation. But why this should be a law of nature if each species has been independently created no man can explain. 44. __________ Many other facts are, as it seems to me, explicable on this theory. How strange it is that a bird, under the form of a woodpecker, should prey on insects on the ground and that upland geese which rarely or never swim, should possess webbed feet, and so in endless other cases. But on the view of each species constantly trying to increase in number, with natural selection always ready to adapt the slowly varying descendants of each to any unoccupied or ill-occupied place in nature, these facts cease to be strange, or might even have been anticipated. 45. __________ We can to a certain extent understand how it is that there is so much beauty throughout nature; for this may be largely attributed to the agency of selection. That beauty, according to our sense of it, is not universal, must be admitted by every one who will look at some hideous bats with a distorted resemblance to the human face. Sexual selection has given the most brilliant colors, elegant patterns, and other ornaments to the males. With birds it has often rendered the voice of the male musical to the female, as well as to our ears. Flowers and fruit have been rendered conspicuous by brilliant colors in contrast with the green foliage, in order that the flowers may be readily seen, visited and fertilized by insects. As natural selection acts by competition, it adapts and improves the inhabitants of each country only in relation to their co-inhabitants; so that we need feel no surprise at the species of any one country being beaten and supplanted by the naturalized productions from another land. The wonder indeed is, on the theory of natural selection, that more cases of the want of absolute perfection have not been detected.

填空题Marci: Has Patrick moved out yet? Karen: Yes. ______. He's now living in a very nice quiet neighbor- hood.

填空题It has often been remarked that the saddest thing about youth is that it is wasted on the young. Reading a recent newspaper report on a survey conducted among college freshmen, I recalled the regret, "If only I knew then what I know now." The survey disclosed what I had already suspected from informal polls of students. According to the survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are" more materialistic and less altruistic". 41. ______. It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the" altruistic" fields is at a low, along with ethnic and women's studies. On the other hand, enrollment in business programs, engineering and computer science is way up. 42. ______. Frankly, I'm proud of the young lady (not her attitude but her success). But why can't we have it both ways? Can't we educate people for life as well as for a career? I believe we can. If we're not, then that is a fault of our educational system--elementary, secondary and higher. In a time of increasing specialization, a time when 90 percent of all the scientists who have ever lived are currently alive, more than ever we need to know what is truly important in life. 43. ______. Most of us finally come to realize that quality of life is not entirely determined by how much we earn. Sure, everyone wants to be financially comfortable, but we also want to feel that we have a perspective on the world beyond the confines of our occupation; we want to be able to render service to our fellow man and to the world. 44. ______. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. 45. ______. In the long run that's what education really ought to be about. And I think it can be. That's the way it should be. Oscar Wilde had it right when he said that we ought to give our ability to our work but our genius to our lives. Let's hope our educators answer the students cries for career education, but at the same time, let's ensure that the students are prepared for the day when they realize their folly. There's a lot more to life than a job.[A] Academic emphasis on competition, rationality and externals acknowledges only one kind of knowing. It makes students devalue their inner selves or larger social purposes.[B] Not surprising in these hard times, the student's major objective" is to be financially well off." Less important than ever is developing a meaningful philosophy of life.[C] Education must meet the needs of the human spirit. It must assist students to develop a satisfactory personal philosophy and sense of values; to cultivate tastes for literature, music and the arts; to grow in ability to analyze problems and arrive at thoughtful conclusions.[D] That's no surprise either. A friend of mine (a sales representative for a chemical company)was making twice the salary of her college instructors during her first year on the job. And that was four years ago; She must be earning much more now.[E] Most people, somewhere between the ages of 30 and 50, finally arrive at the inevitable conclusion that they could do more than serving a corporation, a government agency, or whatever.[F] But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense.[G] While it's true that we all need a career, preferably a profitable one, it is equally true that our civilization has accumulated an incredible amount of knowledge -- be it scientific or artistic.
