任务书设计内容与任务根据如图所给的三种不同的烟囱出屋面的位置，标出各部分符合规范要求的尺寸，并根据提供的节点一和节点二的结构图补充完整其详细构造做法(钢筋混凝土砂浆卧瓦屋面，屋面防水等级为二级)。
某大型商业建筑工程项目，主体建筑10层。在主体工程进行到第二层时，该层的100根钢筋混凝土柱已浇筑完成并拆模后，监理人员发现混凝土外观质量不良，表面疏松，怀疑其混凝土强度不够(设计要求混凝土抗压强度达到C18的等级)，于是要求承包商出示有关混凝土质量的检验与试验资料和其他证明材料。承包商向监理单位出示其对9根柱施工时混凝土抽样检验和试验结果，表明混凝土抗压强度值(28天强度)全部达到或超过C18的设计要求，其中最大值达到了C30，即30MPa。 如果监理方组织复核性检验，结果证明该批混凝土全部未达到C18的设计要求，其中最小值仅有8MPa，即仅达到C8混凝土等级，应采取哪些处理决定
In a recent book entitled The Psychic Life of Insects, Professor Bouvier says that we must be careful not to credit the little winged fellows with intelligence when they behave in what seems like an intelligent manner. They may be only reacting. I would like to confront the professor with an instance of reasoning power on the part of an insect which cannot be explained away in any other manner. During the summer of 1899, while I was at work on my doctoral thesis, we kept a female wasp at our cottage. It was more like a child of our own than a wasp, except that it looked more like a wasp than a child of our own. That was one of the ways we told the difference. It was still a young wasp when we got it (thirteen or fourteen years old) and for some time we could not get it to eat or drink, it was so shy. Since it was a female we decided to call it Miriam, but soon the children’s nickname for it-- " Pudge" --became a fixture, and "Pudge" it was from that time on. One evening I had been working late in my laboratory fooling around with some gin and other chemicals, and in leaving the room I tripped over a nine of diamonds which someone had left lying on the floor and knocked over my card index which contained the names and addresses of all the larvae worth knowing in North America. The cards went everywhere. I was too tired to stop to pick them up that night, and went sobbing to bed, just as mad as I could be. As I went, however, I noticed the wasp was flying about in circles over the scattered cards. "Maybe Pudge will pick them up," I said half laughingly to myself, never thinking for one moment that such would be the case. When I came down the next morning Pudge was still asleep in her box, evidently tired out. And well she might have been. For there on the floor lay the cards scattered all about just as I had left them the night before. The faithful little insect had buzzed about all night trying to come to some decision about picking them up and arranging them in the boxes for me, and then had figured out for herself that, as she knew practically nothing of larvae of any sort except wasp larvae, she would probably make more of a mess of rearranging them than if she had left them on the floor for me to fix. It was just too much for her to tackle, and, discouraged, she went over and lay down in her box, where she cried herself to sleep. If this is not an answer to Professor Bouvier’s statement, I do not know what is. Professor Bouvier believes that insects ______.
Modern technology and science have produced a wealth of new materials and new ways of using old materials. For the artist this means wider opportunities. There is no doubt that the limitations of materials and nature of tools both restrict and shape a man’s work. Observe how the development of plastics and light metals along with new methods of welding has changed the direction of sculpture. Transparent plastic materials allow one to look through an object, to see its various sides superimposed on each other (as in Cubism or in an X-ray). Today, welding is as prevalent as casting was in the past. This new method encourages open designs, where surrounding and intervening space becomes as important as form itself. More ambiguous than other scientific inventions familiar to modern artists, but no less influential, are the psychoanalytic studies of Freud and his followers, discoveries that have infiltrated recent art, especially Surrealism. The Surrealists, in their struggle to escape the monotony and frustrations of everyday life, claimed that dreams were the only hope. Turning to the irrational world of their unconscious, they banished all dine barriers and moral judgments to combine disconnected dream experiences from the past, present and intervening psychological states. The Surrealists were concerned with overlapping emotions more than with overlapping forms. Their paintings often become segmented capsules of associative experiences. For them, obsessive and often unrelated images replaced the direct emotional message of expressionism. They did not need to smash paint and canvas; they went beyond this to smash the whole continuity of logical thought. There is little doubt that contemporary art has taken much from contemporary life. In a period when science has made revolutionary strides, artists in their studios have not been unaware of scientists in their laboratories. But this has rarely been a one-way street. Painters and sculptors though admittedly influenced by modern science, have also molded and changed our world. If breakup has been a vital part of their expression, it has not always been a symbol of destruction. Quite the contrary, it has been used to examine more fully, to penetrate more deeply, to analyze more thoroughly, to enlarge, isolate and make more familiar certain aspects of life that earlier we were apt to neglect. In addition, it sometimes provides rich multiple experiences so organized as not merely to reflect our world, but in fact to interpret it. According to the passage, it is true that ______.
