单选题Suppose you go into a fruiterer"s shop, wanting an apple—you take up one, and on biting it you find it is sour; you look at it, and see that it is hard and green. You take up another one, and that, too, is hard, green, and sour. The shopman offers you a third; but, before biting it, you examine it, and find that it is hard and green, and you immediately say that you will not have it, as it must be sour, like those that you have already tried. Nothing can be more simple than that, you think; but if you will take the trouble to analyze and trace out into its logical elements what has been done by the mind, you will be greatly surprised. In the first place you have performed the operation of induction. You find that, in two experiences, hardness and greenness in apples went together with sourness. It was so in the first case, and it was confirmed by the second. True, it is a very small basis, but still it is enough from which to make an induction; you generalize the facts, and you expect to find sourness in apples where you get hardness and greenness. You found upon that a general law, that all hard and green apples are sour; and that, so far as it goes, is a perfect induction. Well, having got your natural law in this way, when you are offered another apple which you find it hard and green, you say, "all hard and green apples are sour; this apple is hard and green; therefore, this apple is sour." That train of reasoning is what logicians call a syllogism, and has all its various parts and terms—its major premises, its minor premises, and its conclusion. And by the help of further reasoning, which, if drawn out, would have to be exhibited in two or three other syllogisms, you arrive at your final determination, "I will not have that apple." So that, you see, you have, in the first place, established a law by induction, and upon that you have founded a deduction, and reasoned out the special particular case. Well now, suppose, having got your conclusion of the law, that at some times afterwards, you are discussing the qualities of apple with a friend; you will say to him, "It is a very curious thing, but I find that all hard and green apples are sour!" Your friend says to you, "But how do you know that?" You at once reply, "Oh，because I have tried them over and over again，and have always found them to be so." Well, if we are talking science instead of common sense, we should call that an experimental verification. And, if still opposed, you go further, and say, "I have heard from people, in Somerset shire and Devon shire, where a large number of apples are grown, and in London, where many apples are sold and eaten, that they have observed the same thing." It is also found to be the case in Normandy, and in North America. In short, I find it to be the universal experience of mankind wherever attention has been directed to the subject. Whereupon, your friend, unless he is a very unreasonable man, agrees with you, and is convinced that you are quite right in the conclusion you have drawn. He believes, although perhaps he does not know he believes it, that the more extensive verifications have been made, and results of the same kind arrived at—that the more varied the conditions under which the same results are attained, the more certain is the ultimate conclusion, and he disputes the question no further. He sees that the experiment has been tried under all sorts of conditions, as to time, place, and people, with the same result; and he says with you, therefore, that the law you have laid down must be a good one, and he must believe it.

单选题For this generation of young people, the future looks bleak. Only one in six is working full time. Three out of five live with their parents or other relatives. A large majority—73 percent—think they need more education to find a successful career, but only half of those say they will definitely enroll in the next few years. No, they are not the idle youth of Greece or Spain or Egypt. They are the youth of America, the world's richest country, who do not have college degrees and aren't getting them anytime soon. Whatever the sob stories about recent college graduates spinning their wheels as baristas or clerks, the situation for their less-educated peers is far worse. For this group, finding work that pays a living wage and offers some sense of security has been elusive. Despite the continuing national conversation about whether college is worth it given the debt burden it entails, most high school graduates without college degrees said they believe they would be unable to get good jobs without more education. Getting it is challenging, though, and not only because of formidable debt levels. Ms. McClour and her husband, Andy, have two daughters under 3 and another due next month. She said she tried enrolling in college classes, but the workload became too stressful with such young children. Mr. McClour works at a gas station. He hates his work and wants to study phlebotomy, but the nearest school is an hour and half away. Many of these young people had been expecting to go to college since they started high school, perhaps anticipating that employers would demand skills high schools do not teach. Just one in ten high school graduates without college degrees said they were " extremely well prepared by their high school to succeed in their job after graduation. " These young people worried about getting left behind and were pessimistic about reaching some of the milestones that make up the American dream. More than half — 56 percent — of high school graduates without college diplomas said that their generation would have less financial success than their parents. About the same share believed they would find work that offered health insurance within that time frame. Slightly less than half of respondents said the next few years would bring work with good job security or a job with earnings that were high " enough to lead a comfortable life". They were similarly pessimistic about being able to start a family or buy a home. The online survey was conducted between March 21 and April 2, and covered a nationally representative survey of 544 high school graduates from the classes of 2006-11 who did not have bachelor's degrees. The margin of sampling error was plus or minus 5 percentage points.
