18、 in the future 50 In contrast to logic, there is common sense, or still better, the Spirit of Reasonableness. I think of the Spirit of Reasonableness as the highest and sanest ideal of human culture, and the reasonable man as the highest type of cultivated human being. No one can be perfect; he can

19、only aim at being a likeable, reasonable being. In fact, 1 look forward to the time when the people of the world will be informed with this reasonable spirit, both in their personal and their national affairs. Reasonable nations live in peace and reasonable husbands and wives live in happiness. In t

20、he selection of husbands for my daughters, I shall have only one standard: is he a reasonable person? We cannot imagine perfect husbands and wives who never quarrel; we can only conceive of reasonable husbands and wives who quarrel reasonably and then patch up reasonably. Only in a world of reasonab

21、le beings can we have peace and happiness. The Reasonable Age, if that should ever come about, will be the Age of Peace. It will be the age in which the Spirit of Reasonableness prevails. The Spirit of Reasonableness is the best thing that China has to offer to the West. I do not mean that Chinese w

22、arlords are reasonable when they tax the people fifty years ahead; I mean only that the Spirit of Reasonableness is the essence and best side of Chinese civilization. I had this discovery of mine accidentally confirmed by two Americans who had lived a long time in China. One, who had lived in China

23、for thirty years, said that the foundation of all Chinese social life is based on the word chiangli, or “talk reason“. In a Chinese quarrel, the final clinching argument is, “Now is this reasonable?“ and the worst and commonest condemnation is that a man “pu chiangli“ or “does not talk reason. “The

24、man who admits being “unreasonable“ is already defeated in the dispute. I have said that: “For a Westerner, it is usually sufficient for a proposition to be logically sound. For a Chinese it is not sufficient that a proposition be logically correct, but it must be at the same time in accord with hum

25、an nature. In fact to be in accord with human nature, to be chinching (i.e. , to be human), is a greater consideration than to be logical. “ “The Chinese word for reasonableness is chingli, which is composed of two elements, ching (jenching) or human nature, and li (tienli) or eternal reason. Ching

26、represents the flexible, human element, while li represents the immutable law of the universe. “ A cultured man is one who understands thoroughly the human heart and the laws of things. By living in harmony with the natural ways of the human heart and of nature, the Confucianist claims that he can b

27、ecome a sage. But then the sage is no more than a reasonable person, like Confucius, who is chiefly admired for his plain, common sense and his natural human qualities, i. e. , for his great humanness. 51 Based on the argument in the passage, which of the following is the highest and sanest ideal of

28、 human culture? （ A） Common sense. （ B） Exquisite logic. （ C） Humanized thinking. （ D） Appreciation of human civilization. 52 According to the author, an ideal relationship between husband and wife is obtainable through （ A） constant communication （ B） perfect personality （ C） quitting quarrelling （

29、 D） being understandable and considerate 53 We can infer from the usual final argument in a Chinese quarrel (the second paragraph) that （ A） an idea must be logically acceptable （ B） one may feel ashamed at his lack of common sense （ C） a decline in morals is forgivable in Chinese culture （ D） one s

30、hould have a good understanding of human nature to win the quarrel 54 As age like Confucius is chiefly admired in Chinese culture for all the following EXCEPT_. （ A） absence of pretense （ B） sound knowledge of human nature （ C） excellent performance in his schooling （ D） an adorable command of truth

31、 55 Which of the following statements is INCORRECT? （ A） A westerner is never satisfied with logical soundness. （ B） Peace derives from reason. （ C） Being human is to be reasonable. （ D） A civilized man is one who knows well laws of nature. TEXTB 55 In 2006, I made a commitment to gradually give all

32、 of my Berkshire Hathaway stock to philanthropic foundations. I couldnt be happier with that decision. Some material things make my life more enjoyable; many, however, would not. I like having an expensive private plane, but owning a half-dozen homes would be a burden. Too often, a vast collection o

33、f possessions ends up possessing its owner. The asset I most value, aside from health, is interesting, diverse, and long-standing friends. My wealth has come from a combination of living in America, some lucky genes, and compound interest. Both my children and I won what I call the ovarian lottery.

34、(For starters, the odds against my 1930 birth taking place in the U. S. were at least 30 to 1. My being male and white also removed huge obstacles that a majority of Americans then faced. ) My luck was accentuated by my living in a market system that sometimes produces distorted results, though over

35、all it serves our country well. Ive worked in an economy that rewards someone who saves the lives of others on a battlefield with a medal, rewards a great teacher with thank-you notes from parents, but rewards those who can detect the mispricing of securities with sums reaching into the billions. In

36、 short, fate s distribution of long straws is wildly capricious. The reaction of my family and me to our extraordinary good fortune is not guilt, but rather gratitude. Were we to use more than 1% of my claim checks on ourselves, neither our happiness nor our well-being would be enhanced. In contrast

37、, that remaining 99% can have a huge effect on the health and welfare of others. That reality sets an obvious course for me and my family: Keep all we can conceivably need and distribute the rest to society, for its needs. My pledge starts us down that course. 56 According to the author, which of th

38、e following can NOT bring happiness? （ A） Enough material things. （ B） Sound relations with people. （ C） Having a luxurious private plane. （ D） A long list of properties. 57 All of the following contribute to the authors big fortune EXCEPT_. （ A） being an American （ B） considerable interest in life

39、（ C） a circle of rich friends （ D） being a white man 58 In the sentence “In short, fates distribution of long straws is wildly capricious“ (the fourth paragraph) , the word “capricious“ in the sentence means_. （ A） unpredictable （ B） concerned （ C） conspicuous （ D） faithful 59 At the end of the pass

40、age, the author decides to_. （ A） give away all his fortune for a sense of guilt （ B） keep half of his fortune for the improvement of his life （ C） make a profit from the remaining 99% of his property （ D） pledge most of his wealth to charity 60 Which might be the most appropriate title for the pass

41、age? （ A） Materialism Versus Idealism. （ B） My Philanthropic Pledge. （ C） The Significance of Success. （ D） How to Live a Happy Life. 60 I see this principal all over as I go through my day. I see rims on car wheels that cost upwards of $ 500, just for a little bit of decoration on a vehicle. I see

42、people spend four or five dollars for a cup of coffee, hundreds of dollars for cell phones that they almost never use, thousands of dollars on huge television sets that they almost never watch. All around us are ads and commercials that keep us wanting to buy things that keep us dissatisfied with th

43、e way things are, and those ads and commercials are trying to convince us that if we just buy some more stuff no matter what the cost well be happier and more content. But somewhere along the line we have to learn to make our own decisions about value. Theres a common law of economics that states th

44、at many poor people will stay poor because of the decisions that they make about how to spend their money. How many people have you known or known of, for example, who have little money yet who buy a very expensive car with high monthly payments? And how many people are in trouble right now because

45、they bought houses that were more expensive than they could afford? While I wouldnt say that the answer to our money issues would be to skimp and save every penny and never have any fun in life, it is important that we learn about value and about when to spend how much. A few years ago, for example,

46、 my wife and I had cell phones. At the time I worked half an hour from home, I was on the road with sports teams a lot, and my wife also was on the road quite a bit. The cell phones made sense, even though we didnt use them much at least we knew that if anything happened, we could contact one anothe

47、r. Then we moved someplace where we didnt need the phones any more, for we both worked close to one another and we werent on the road much. Suddenly, the $ 75 every month to keep the phones made no sense, so we got rid of them. They were now just a luxury item, no longer as necessary as they were be

48、fore. They simply didnt have the same value that they had had before. And even though it had been quite convenient to make an occasional phone call from wherever I happened to be, that convenience was no longer worth the amount of money we would have had to pay to maintain it. The best that we can d

49、o is to learn to define the value of our money for ourselves and to exchange our money for goods and services that have equal or even greater value. Money is here, and its a part of our lives. We can live with it and have it work for us, or we can squander it and lose it and become angry and frustrated with our loss. The choice is ours, but one thing is for sure the path to happiness doesnt lie in exchanging our money for goods or services of littl
