UNIT 5 Reading Passage 5 10 15 20 20 25 Listening There is a saying in France that states: "The government could fall, the Louvre¹ could be broken into, or aliens could land on Earth, but if any of these things happened during the Tour de France, no one would notice." The Tour de France is the most famous cycling race in the world. The which is held in July every year, consists of twenty one-day stages, plus several rest days. The course follows a clockwise route around France, and often neighboring countries, including Luxembourg, Belgium, and Italy. The winner is the rider who completes all twenty stages of the race in the shortest overall time. race, The Tour de France first started on July 1, 1903, when sixty cyclists left from in front of The Alarm Clock Café, just outside of Paris, and rode 467 kilometers to Lyon. The first race consisted of six legs, each of which was about 400 kilometers long. At that time, there were no rest days the winner was the rider who finished the race in the shortest total time. The winner of the first Tour de France, Maurice Garin, the most popular cyclist in France at that time, received 2,000 francs (about $350). It took him 94 hours and 33 minutes to ride all 2,428 kilometers of the race, three hours faster than the runner-up.² Over the weeks during which the race was run, the idea of the Tour de France slowly caught on with the people of France. The race has been held every year since that time, except during the years of World Wars I and II.³ The Tour de France has developed several special honors for which racers compete. The highest honor is the "yellow jersey." Henri Desgranges, the founder of the race, introduced the yellow jersey in 1919 to show the leading racer each day of the Tour de France. Each day, the officials who keep track of all of the riders' times compare each rider's total time up to that point. The racer with the lowest overall time wears the yellow jersey during the following day's race. Other honors include the "green jersey," which is given to the best sprinter, and the "polka dot jersey," a white jersey with red dots, for the best rider in the mountains along the route. Over the years of the race, the competitors have gained a reputation for good sportsmanship. For example, if a lead rider falls off his bike, it is common for the following riders to slow down to allow the fallen rider to catch up. Some watchers are surprised by this, but as German rider Jan Ullrich, who came in runner-up in 2002 after waiting for winner Lance Armstrong, says, "Of course I would wait. If I would have won this race by taking advantage of someone's bad luck, then the race was not worth winning." 1 the Louvre a famous museum in Paris 2 runner-up someone who comes second in a race or other competition 3 World Wars I and II 1914-1918 and 1939 - 1945 abent ages

UNIT 1 5 Reading Passage 10 15 20 20 25 Listening There are more than 37,000 known species of spiders in the world in a wide variety of shape's and sizes! The largest spiders in the world live in the rain forests of South America and are known by the people who live there as the "bird-eating spiders." These spiders can grow up to 28 centimeters in length- about the size of a dinner plate, and, as their name suggests, have been known to eat small birds. In comparison, the smallest species of spider in the world is native to Western Samoa. These tiny spiders are less than half a millimeter long — about the size of a period on this page and live in plants that grow on mountain rocks. - Some people like to keep spiders as pets, particularly tarantulas, which are native to North America and can live for up to twenty-five years, Most people, on the other hand, do not like touching spiders, and a significant number of people are afraid of them, mainly because of their poison. However, despite their bad reputation, only thirty of the 37,000 known species of spiders are deadly to humans. Spiders actually provide benefits to humans, by catching and eating harmful insects such as flies and mosquitoes. - - The main thing that makes spiders different from other animals is that they spin web's to catch the small insects they feed on. The unique silk of a spider's web is produced by special organs found spider web is five times in the lower part of the spider's body. It is light, elastic, and strong stronger than steel. Additionally, it is completely biodegradable. This means that the web will making it perfect for uses completely decompose¹ and eventually return to nature over time such as making fishing nets. Some people have tried to raise spiders commercially in order to collect the silk these spiders produce, but no one has ever really managed to make a go of it. One reason why these businesses never stand a chance is because it takes 670,000 spiders to produce half a kilogram of silk, and all of these spiders need living insects for their food. In addition, spiders are usually solitary² animals, and need to be kept alone. Researchers at an American company working together with two U.S. universities may have found a solution to making artificial spider web. Using genetically modified silkworms,³ the company hopes that in the long run it will be able to make large quantities of very light, very strong fiber for medical as well as other uses. Additionally, because the manufacture of the artificial web is from living silkworms, the industry potentially would be non-polluting and less harmful to the environment

【物理、光の性質、フィゾーの光速測定】 2枚目に書いたんですけど、これが質問です。 ずっと考えても調べても出てきませんでした。 教えて欲しいです

例題 フィゾーの光速測定 AP₁ ・ゾーは、右図のような装置を用いて, 初めて地球上で光速を測定した。最初,歯車 止まっているときには、歯の間を光が通り, 遠くにある平面鏡に反射して再び歯の間を通 り抜けて戻ってくる。歯車を回転させると, 光が反射して戻ってくる間に歯が動くので 回転数を上げていてことで反射光が歯に遮ら れてしだいに暗くなる。 さらに回転を速くし ていくと,再び明るく見えるようになり, 最 でも明るくなるときの回数から光速が求められる。 いま 歯数4000の歯車を用い ると、回転数が毎秒201 回転数が毎秒20回になったときに初めて最も明るくなり、光速の値として /3.0 x 10°m/s が得られた。 歯車と平面鏡との間の距離はいくらか。 Plate UTA 2 反射光が一度暗くなって再 び明るくなるのは, 歯が1コマ 分だけずれたことによる。 センサー 84 フィジーの光速測定 歯がコマ分回転した時 間と、光が歯と平面鏡と の間を1復めた時間とが 4個/IS 1849年,8.6kmの距離に光を往復させて光速測定を行った。 1960 半線の奴 光源 3.0×10+ S 観測者 解答 反射光が最も明るく見えるのは、歯 車の歯が1コマ動く間に, 光が歯車から 平面鏡までの距離L [m]の区間を1往復 2L 3.0×10° ハーフミラー このときするときである。 光の通り道を1s間に 通過する歯の数は、 1000×30=3.0×10 [個/s] 歯車の歯が1コマ動くのに要する時間は、 るから、 1 id H 歯車 V ・276 1 3.0×10^ 平面鏡 1コマ 光 sであ NA-AM ゆえに, L = 5.0×10'[m〕
