W: Sure. Weren't you in class on Monday？ That's when it was given out. M: No, I missed that class. Was there a handout？ W: No, the instructor just wrote the assignment on the board. M: Could I copy the assignment from your notes？ W: You could, ff I had copied it all down; but I just wrote down the part that I wanted. M: Oh, no. W: You see, there were four choices of topics ior the term paper; but, when I saw them, I knew which one I wanted so I didn't copy the others down. M: Can you remember any o'f the others？ W: Let's see. There was one about World War I, something about it, but I don't remember what, and there was one called "the idea of progress in the nineteenth century." M: And what was the last one？ W: I can't remember. My mind is a complete blank. Maybe you can ask someone else. M: Yes, I will. Anyway, those are certainly broad topics. W: Yes, but you van focus on a special area within them. Which one would you take？ M: Of course, I don't know what the last one is, but of these three, I think I'd take "the idea of progress." W: That's very abstract. M: Yes, but it's one of my interests and I've read a lot on the subject. I've never written a term paper on it though. W: Me neither. I haven't even read about it. Are you going to class on Wednesday？ M: Yes. W: Maybe he'll write it on the board again. M: I hope so. Good luck with your paper. W: Same to you. (23) A．Three. B．Four. C．Five. D．Six.

【77】 Instead of trying to make gradual changes in small increments, make big changes. After all, big changes are relatively easier to make than are small ones. Some people assume that the way to bring about improvement is to make the change small enough so that nobody will notice it. This approach has never worked, and one can' t help but wonder why such thinking continues. Everyone knows how to resist small changes; they do it all the time. If, however, the change is big enough, resistance can' t be mobilized against it.【78】 Management can make a sweeping organizational change, but just let a manager, try to change someone' s desk from here to there, and see the great difficulty he encounters. All change is resisted, so the question is how can the changes be made big enough so that they have a chance of succeeding？ Buck Minster Fuller has said that instead of reforms society needs new forms; e. g. , in order to reduce traffic accidents, improve automobiles and highways instead of trying to improve drivers. The same concept should be applied to human relations. There' s a need to think in terms of social architecture, and to provide arrangements among people that evoke what they really want to see in them selves.【79】 Mankind takes great pains with physical architecture, and is beginning to concern it self with the design of systems in which the human being is a component. But most of these designs are only for safety, efficiency, or productivity. System designs are not made to affect those aspects of life people care most about such as family life, romance, and esthetic experiences.【80】 Social technology as well as physical technology need to be applied in making human arrangements that will transcend anything mankind has yet experienced. People need not be victimized by their environments; they can be fulfilled by them. (76)
