单选题 "The language of a composer", Cardus wrote, "his harmonies, rhythms, melodies, colors and texture, cannot be separated except by {{U}}pedantic{{/U}} analysis from the mind and sensibility of the artist who happens to be expressing himself through them". But that is precisely the trouble; for as far as I can see, {{U}}Mozart's{{/U}} can. Mozart makes me begin to see ghosts, or at the very least ouija-boards. If you read Beethoven's letters, you feel that you are at the heart of a tempest, a whirlwind, a furnace; and {{U}}so you should{{/U}}, because you are. If you read Wagner's, you feel that you have been run over by a tank, and that, too, is an appropriate response. But if you read Mozart's—and he was a hugely prolific letter-writer—you have no clue at all to the power that drove him and the music it squeezed out of him in such profusion that death alone could stop it; they reveal nothing—nothing that explains {{U}}it{{/U}}. Of course it is absurd(though the mistake is frequently made)to seek external causes for particular works of music; but with Mozart it is also absurd, or at any rate useless, to seek for internal ones either. Mozart was an instrument. But who was playing it? That is what I mean by the Mozart Problem and the anxiety it causes me. In all art, in anything, there is nothing like the perfection of Mozart, nothing to compare with the range of feeling he explores, nothing to equal the contrast between the simplicity of the materials and the complexity and effect of his use of {{U}}them{{/U}}. The piano concertos themselves exhibit these truths at their most intense; he was a greater master of this form than of the symphony itself, and to hear every one of them, in the astounding abundance of genius they provide, played as I have so recently heard them played, is to be brought face to face with a mystery which, if we could solve it, would solve the mystery of life itself. We can see Mozart, from infant prodigy to unmarked grave. We know what he did, what he wrote, what he felt, whom he loved, where he went, what he died of. We pile up such knowledge as a child does bricks; and then we hear the little tripping rondo tune of the last concerto—and the bricks collapse; all our knowledge is useless to explain a single bar of it. It is almost enough to make me believe in — but I have run out of space, and don't have to say it. Put K. 595 on the gramophone and say it for me.

单选题What we have to get from the sound-waves is enough information to build the {{U}}support{{/U}} of the remark, as it were, and then the brain will complete the entire language structure with no trouble at all. A. standing B. scaffolding C. structuring D. scamping

单选题Many students agreed to come, but some students against because they said they don''t have time.

单选题 {{U}}Children are a relatively modem invention{{/U}}. Until a few hundred years ago they look like adult, wearing grown-up clothes and grown-up expressions, performing grown-up tasks. Children did not exist because the family as we know it had not evolved. Children today not only exist; they have taken over in no place more than in America, and at no time more than now. It is always Kids Country here. Our civilization is child-centered, child-obsessed. A kid's body is our physical ideal. {{U}}In Kids Country we do not permit middle-aged{{/U}}. Thirty is promoted over 50, but 30 knows that soon his time to be overtaken will come. We are the first society in which parents expect to learn from their children. Such a topsy-turvy situation has come to abort at least in part because, unlike the rest of the world, ours is an immigrant society, and for immigrants the only hope is in the kids. {{U}}In the Old Country{{/U}}, that is, Europe, hope was in the father, and how much wealth he could accumulate and pass along to his children. In the growth pattern of America and its ever- expanding frontier, the young man was ever advised to GO WEST; the father was ever inheriting from his son. Kids Country may be the inevitable result. Kids Country is not at all bad. America is the greatest country in the world to grow up in because it is Kids Country. We not only wear kids clothes and eat kids food; we dream kids dreams and make them come tree. It was, after all, a boys' game to go to the moon. If in the old days children did not exist, it seems equally true today that adults, as a class, have begun to disappear, condemning all of us to remain boys and girls forever, jogging and doing push-ups against eternity.

单选题Lichens may grow on the bark of a tree in a steaming tropical rain forest, on the bricks of big city buildings, on rocks in hot springs, on wind-swept mountaintops, and in the driest desserts. In the arctic, they provide the principal food for caribou, and they are one of the few plants that grow in Antarctica. They are pioneers, appearing in barren rocky areas and starting the formation of soil in which mosses, then ferns, and then other plants can take root. Lichens are a partnership of two plants — fungi and algae. The lichen body is made up of a network of fungal strands. In the upper layers of these grow groups of algae. The two organisms live together to the benefit of both, a relationship known as symbiosis. The fungi provide support, absorb water, and shelter the tender algae from direct sunlight. The algae carry on photosynthesis and provide the fungi with food. The algae can live independently and are recognizable as a species that grows alone. The fungi, on the other hand, cannot live apart from their partners. They can be placed in known classes of fungi but are unlike any species that lives independently. So definite are the form, color, and characteristics of these double organisms that for hundreds of years, they were classified as one. More than 15,000 "species" were named. If these organisms are classified as separate species, it is difficult to fit them into the existing system of classification. But if they are classified separately, these species of fungi seem rather strange. Lichens are a splendid example of the difficulties faced by taxonomists in classifying species.
