Ⅱ 英文を読み、下記の問いに答えなさい。 (7) Like a tiny submarine, the chambered nautilus speeds through the ocean on little jets that it creates by sucking in water and spitting it out. However, as ways of movement go, jet propulsion is not usually a (8) very good use of energy. In the ocean's depths where oxygen gets thin, the nautilus seems to be putting itself at risk by expending so much effort on movement. Fish use far less energy by pushing at the water with their fins. So how does it manage to jet around unscathed in the ocean's depths? Graham Askew, a biomechanics professor at the University of Leeds, set out with a graduate student, Thomas Neil, to understand better how this shellfish moves. They found that the nautilus is actually a (9) highly efficient jet-propelled creature, wasting much less energy than

11 脊髄再生医療 英文] 11 It was a miracle of almost biblical proportions. In 1998, scientists in Israel revealed that rats whose spinal cords had been severed had called walked again after an injection of healing immune cells macrophages. Their hopes buoyed by enthusiastic media coverage, = paralysed patients began to dream of taking their own tentative steps. 12 Five years on, the status of those dreams remains unclear. Proneuron Biotechnologies, a Los Angeles-based company founded on the back of the research of lead investigator Michal Schwartz at the Weizmann Institute of Science in Rehovot, is expected soon to release the results of an initial trial of the procedure on eight patients with spinal injuries. Media reports have indicated that some patients have recovered some feeling and movement, but many researchers do not expect a repeat of the rodent miracle. Indeed, they claim that at least one group has since tried, and failed, to reproduce Schwartz's original animal results.

木版画 鋳造 第3問 以下の文は、 S. Strandh の “Machines, an illustrated history" からの抜粋で ある。 次の文を読んで、設問に解答せよ。 (ア) The tools of precision mechanics were, without doubt, the technical pre conditions for making wood cuts and for the development of printing. The oldest dated wood engraving is from 1418. It shows fine lines throughout 細部 and a richness of detal, which imply that the tools used, the knives, burins, and so on, must have been eminently suitable At this time, it was only the precision mechanics of clock making which could achieve the technique required for such tools. 精密機械技術 (イ) A (woodcut was produced by transferring a drawing, reversed from left to right, onto a carefully surface-ground "block" of wood, after which the surface wood on either side of each line in the drawing was cut away with a burin of forged steel. The remaining wood on all 'surfaces which were to be white in the drawing were then cut away with gravers and gouges, so that the lines of the drawing became raised. They were then inked and pressed against paper. これは 理由では ないから、 (~のときに、何 が原因か は不明) The woodcut method spread rapidly in the late Middle Ages when pictures were rarity. At first, skilful craftsmen made the woodcuts, but before long, eminent artists were themselves cutting their own drawings in wood. One of the first was the German Albrecht Duerer (1479-1528) who, in 1498, published the famous pictorial series of the Revelation of St. John. Graphics had become an independent art form-based on the progress of precision 酒の mechanics! 可動式の The 1440s saw the first book printed with movable die-cast type. (The letter press printing method used by Johann Gutenberg (1399?-1468) was basically the same as the one used for printing woodcuts, but Gutenberg used cast, movable type instead of cut blocks. The production of dies for the type was made possible by the tools of precision mechanics, too. It does not detract from Gutenberg's contribution that printing with movable type has been practised in the Far East, or more specifically Korea, two thousand years prior to this. Several of the techniques described here, which developed so quickly during the technical revolution of the Renaissance, had had predecessors in other parts of the world.
