单选题{{B}}Passage Four{{/B}} Dearest Scottie: I don't think I will be writing letters many more years and I wish you would read this letter twice--bitter as it may seem. You will reject it now, but at a later period some of it may come back to you as truth. When I'm talking to you, you think of me as an older person, an "authority," and when I speak of my own youth what I say becomes unreal to you--for the young can't believe in the youth of their fathers. But perhaps this little bit will be understandable if I put it in writing. When I was your age I lived with a great dream. The dream grew and I learned how to speak of it and make people listen. Then the dream divided one day when I decided to marry your mother after all, even though I knew she was spoiled and meant no good to me. I was sorry immediately I had married her but, being patient in those days, made the best of it and got to love her in another way. Yor came along and for a long time we made quite a lot of happiness out of our lives. But I was a man divided-- she wanted me to work too much for her and not enough for my dream. She realized too late that work was dignity, and the only dignity, and tried to atone for it by working herself, but it was too late and she broke and is broken forever. …… The mistake I made was in marrying her. We belonged to different worlds--she might have been happy with a kind simple man in a southern garden. She didn't have the strength for the big stage-- sometimes she pretended, and pretended beautifully, but she didn't have it. She was soft when she should have been hard, and hard when she should have been yielding. She never knew how to use her energies--she's passed that failling onto you. For a long time I hated her mother for giving her nothing in the line of good habit-- nothing but "getting by" and conceit. I never wanted to see again in this world women who were brought up as idlers. And one of my chief desires in life was to keep you from being that kind of persons, one who brings ruin to themselves and others. When you began to show disturbing signs at about fourteen, I comforted myself with the idea that you were too precocious socially and a strict school would fix things. But sometimes I think that idlers seem to be a special class for whom nothing can be planned, plead as one will with them--their only contribution to the human family is to warm a seat at the common table. ……

单选题{{B}}Passage Four{{/B}} The study of philosophies should make our own ideas flexible. We are all of us apt to take certain general ideas for granted, and call them common sense. We should learn that other people have held quite different ideas, and that our own have started as very original guesses of philosophers. A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a great many of the questions on which philosophers still argue. For example, Plato thought that when we saw something, one ray of light came to it from the sun, and another from our eyes and that seeing was something like feeling with a stick. We now know that the light comes from the sun, and is reflected into our eyes. We don't know in much detail how the changes in our eyes give rise to sensation. But there is every reason to think that as we learn more about the physiology of the brain, we shall do so, and that the great philosophical problems about knowledge are going to be pretty fully cleared up. But if our descendants know the answers to these questions and others that perplex us today, there will still be one field of which they do not know, namely the future. However exact our science; we cannot know it as we know the past. Philosophy may be described as argument about things of which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment. That is one reason why Marx and Engels quite rightly wrote to many philosophical problems that interested their contemporaries. But we have got to prepare for the future, and we cannot do so rationally without some philosophy. Some people say we have only got to do the duties revealed in the past and laid down by religion, and god will look after the future. Others say that the world is a machine and the course of future events is certain, whatever efforts we may make. Marxists say that the future depends on ourselves, even though we are part of the historical process. This philosophical view certainly does inspire people to very great achievements. Whether it is true or not, it is powerful guide to action. We need a philosophy, then, to help us to tackle the future. Agnosticism easily becomes an excuse for laziness and conservatism. Whether we adopt Marxism or any other philosophy, we cannot understand it without knowing something of how it developed. That is why knowledge of the history of philosophy is important to Marxists, even during the present critical days.

单选题Over the past century, all kinds of unfairness and discrimination have been condemned or made illegal. But one insidious form continues to thrive: alphabetize. This, for those as yet unaware of such a disadvantage, refers to discrimination against those whose surnames begin with a letter in the lower half of the alphabet. It has long been known that a taxi firm called AAAA cars has a big advantage over Zodiac cars when customers thumb through their phone directories. Less well known is the advantage that Adam Abbott has in life over Zoe Zysman. English names are fairly evenly spread between the halves of the alphabet. Yet a suspiciously large number of top people have surnames beginning with letters between A and K. Thus the American president and vice-president have surnames starting with B and C respectively; and 26 of George Bush's predecessors (including his father) had surnames in the first half of the alphabet against just 16 in the second half. Even more striking, six of the seven heads of government of the G7 rich countries are alphabetically advantaged (Ber-lusconi, Blair, Bush, Chirac, Chretien and Koizumi). The world's three top central bankers (Greenspan, Duisenberg and Hayami) are all close to the top of the alphabet, even if one of them really uses Japanese characters. As are the world's five richest men (Gates, Buffet, Allen, Ellison and Albrecht). Can this merely be coincidence? One theory, dreamt up in all the spare time enjoyed by the alphabetically disadvantaged, is that the rot sets in early. At the start of the first year in infant school, teachers seat pupils alphabetically from the front, to make it easier to remember their names. So short-sighted Zysman junior gets stuck in the back row, and is rarely asked the improving questions posed by those insensitive teachers. At the time the alphabetically disadvantaged may think they have had a lucky escape. Yet the result may be worse qualifications, because they get less individual attention, as well as less confidence in speaking publicly. The humiliation continues. At university graduation ceremonies, the ABCs proudly get their awards first; by the time they reach the Zysmans most people are literally having a ZZZ. Shortlists for job interviews, election ballot papers, lists of conference speakers and attendees: all tend to be drawn up alphabetically, and their recipients lose interest as they plough through them.
