单选题What if our society uses new-found technologies of "genetic engineering" to interfere with the biological nature of human beings? Might that not be disastrous? What about cloning, for instance? Cloning is a term originally used in connection with nonsexual reproduction of plants and very simple animals. Now it is coming into use in connection with higher animals, since biologists are finding ways of starting with an individual cell of a grown animal and inducing it to multiply in the same way in the future. But is cloning a safe thing to unleash on society? Might it not be used for destructive purposes? For instance, might not some ruling group decide to clone their submissive, downtrodden peasantry, and thus produce endless hordes of semi-robots who will slave to keep a few in luxury and who may even serve as endless ranks of soldiers designed to conquer the rest of the world? A dreadful thought, but an unnecessary fear. For one thing, there is no need to clone for the purpose. The ordinary method of reproduction produces all the human beings that are needed and as rapidly as is needed. Right now, the ordinary method is producing so many people as to put civilization in danger of imminent destruction. What more can cloning do? Secondly, unskilled semi-robots cannot be successfully pitted against the skilled users of machine, either on farms, in factories or in armies. Any nation depending on downtrodden masses will find itself an easy mark for exploitation by a less populous but more skilled and versatile society. This has happened in the past often enough. But even if we forget about self-hordes, what about the cloning of a relatively few individuals? There are rich people who could afford the expense, or politicians who could have the influence for it, or the gifted who could undergo it by popular demand. There can be two of a particular banker or governor or scientist—or three—or a thousand. Might this not create a kind of privileged caste, who would reproduce themselves in greater and greater numbers, and who would gradually take over the world? Before we grow concerned about this, we must ask whether there will really be any great demand for cloning. Would you want to be cloned? The new individual that is formed by your cell will have your genes and therefore your appearance and, possibly, talents, but he will not be you. The clone will be, at best, merely your identical twin. Identical twins share the same genetic pattern, but they each have their own individuality and are separate persons. Cloning is not a pathway to immortality, then, because your consciousness does not survive in your clone, any more than it would in your identical twin if you had one. In fact, your clone would be far less than your identical twin. What shapes and forms a personality is not genes alone, but all the environment to which it is exposed. Identical twins grow up in identical surroundings, in the same family, and under each other's influence. A clone of yourself, perhaps thirty or forty years younger would grow up in a different world altogether and would be shaped by influences that would be sure to make him less and less like you as he grows older. He may even earn your jealousy. After all, you are old and he is young. You may once have been poor and struggled to become well-to-do, but he will be well-to-do from the start. The mere fact that you won't be able to view him as a child, but as another competing and better-advantaged you, may accentuate the jealousy. No! Imagine that, after some initial experiments, the demand for cloning will be virtually nonexistent.

单选题Can animals have a sense of humor? Sally Blanchard, publisher of a newsletter called the Pet Bird Report, thinks a pet parrot may have pulled her leg. That's one explanation for the time her African gray parrot, named Bongo Marie, seemed to feign distress at the possible death of an Amazon parrot named Paco. It happened one day when Blanchard was making Cornish game hen for dinner. As Blanchard lifted her knife, the African gray threw back its head and said, "Oh, no! Paco!" Trying not to laugh, Blanchard said, "That's not Paco," and showed Bongo Marie that the Amazon was alive and well. Mimicking a disappointed tone, Bongo Marie said, "Oh, no," and launched into a hoarse laugh. Was the parrot joking when it seemed to believe the other bird was a goner? Did Bongo Marie comprehend Blanchard's response? Studies of African grays have shown that they can understand the meaning of words--for example, that red refers to a color, not just a particular red object. Parrots also enjoy getting a reaction out of humans, and so, whether or not Bongo Marie's crocodile tears were intentional, the episode was thoroughly satisfying from the parrot's point of view.

单选题What feature sets apart the three dictionaries discussed in the passage from traditional ones ?

单选题Being a man has always been dangerous. There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity, and among 70-year-olds there are twice as many women as men. But the great universal of male mortality is being changed now, by babies survive almost as well as girls do. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mate. More important, another chance for natural selection has been removed. Fifty years ago, the chance of a baby(particularly a boy baby)surviving depended on its weight. A kilogram too light or too heavy meant almost certain death. Today it makes almost no difference. Since much of the variation is due to genes one more agent of evolution has gone. There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women has 15 children. Nowadays, the number of births, like the age of death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples. The grand mediocrity of today everyone being the same in survival and number of offspring means that natural selection has lost 80% of its power in upper-middle-class India compared to the tribes. For us, this means that evolution is over; the biological Utopia has arrived. Strangely, it has involved little physical change. No other species fills so many places in nature. But in the pass 100,000 years — even the pass 100 year our lives have been transformed but our bodies have not. We did not evolve, because machines and society did it for us. Darwin had a phrase to describe those ignorant of evolution: they "look at an organic being as average looks at a ship, as at something wholly beyond his comprehension." No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were, they will look just like us.

单选题Analysts have had their go at humor, and I have read some of this interpretative literature, but without being greatly instructed. Humor can be dissected, as a frog can, but the thing dies in the process and the innards (内在部分) are discouraging to any but the pure scientific mind. In a newsreel theatre the other day I saw a picture of a man who had developed the soap bubble to a higher point than it had ever before reached. He had become the ace soap bubble blower of America, had perfected the business of blowing bubbles, refined it, doubled it, squared it, and had even worked himself up into a convenient lather. The effect was not pretty. Some of the bubbles were too big to be beautiful, and the blower was always jumping into them or out of them, or playing some sort of unattractive trick with them. It was, if anything, a rather repulsive sight. Humor is a little like that: it won't stand much blowing up, and it won't stand much poking. It has a certain fragility, an evasiveness, which one had best respect. Essentially, it is a complete mystery. A human frame convulsed with laughter, and the laughter becoming mysterious and uncontrollable, is as far out of balance as one shaken with the hiccoughs or in the throes of a sneezing fit. One of the things commonly said about humorist is that they are really very sad people- clowns with a breaking heart. There is some truth in it, but it is badly stated. It would be more accurate, I think, to say that there is a deep vein of melancholy running through everyone's life and that the humorist, perhaps more sensible of it than some others, compensates for it actively and positively. Humorists fatten on trouble. They have always made trouble pay. They struggle along with a good will and endure pain cheerfully, knowing how well it till serve them in the sweet by and by. You find them wrestling with foreign languages, fighting folding ironing boards and swollen drainpipes, suffering the terrible discomfort of tight boot (or as Josh illings wittily called them, "tire boots"). They pour out their sorrows profitably, in a form hat is not quite a fiction nor quite a fact either. Beneath the sparking surface of these dilemmas lows the strong tide of human woe. Practically everyone is a manic depressive of sorts, with his up moments and his down moments, and you certainly don't have to be a humorist to taste the sadness of situation and mood. But there is often a rather fine line between laughing and crying, and if a humorous piece of writing brings a person to the point where his emotional responses are untrustworthy and seem likely to break over into the opposite realm, it is because humor, like poetry, has an extra content. It plays close to the bit hot fire which is Truth, and sometimes the reader feels. the heat.
