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

Read the passage and answer the questions that follow. (1). „Why do batteries matter? Look at all your electronic devices: from laptops to smartphones to Kindles or iPads, even your watch. Those electronics are getting more energy-efficient and require less energy than they used to. But as they do, people get greedy and want their capabilities to increase. The battery, or how much energy you can 05 store in a given volume and weight, is the defining factor in this whole field. Then there are electric cars. If we can make batteries with double the "energy TR2Z density of today's and drive the price below $200 per "kilowatt-hour (versus $300 to $800 today, depending on type and weight), we could have a car with a 300-mile range, even with the air conditioner or heater turned up, that would sell for $25,000 to $30,000. The 10 Department of Energy's goal is to get batteries to $150 per kilowatt-hour by the year 2020. 01 Finally, there are the "utility-scale batteries, which are very important for renewable TR28 energy. Wind and solar power are going to become more common. Wind is already the second-cheapest form of new energy, after shale gas, and it will become the cheapest 15 15 within a decade. Right now "utility companies get about 4 percent of their power from renewable sources other than "hydro- and that 4 percent is roughly all from wind. We may see a day when renewables make up 50, 60, 70 percent of the total supply of energy. Utility companies will need batteries to stabilize the flow of renewable energy into the *grid, and also require a better electrical control system to (3)do the switching. People 20 may have these batteries at their homes instead of generators. All of this would create a huge market. But the effects would be more profound. T There are mountainous places even in the U.S., like western Alaska, that will never be connected to the electric grid. There aren't enough people, and the distances are too great. There are many parts of South Asia like this, too. But they will have solar and 25 wind power - which, in 10 or 15 years, are going to be as cheap as any other form of energy, or cheaper. Once you have "storage systems, you can put a little "solar installation on your roof or "a plot of land, and then you will have your electric supply! It will be like cellphones' "leapfrogging the "land-line era. It will transform the prosperity of the world. 【Notes】 energy density エネルギー密度 (ここでは電池の容量を意味する) kilowatt-hour キロワット時 (1キロワットの機器を1時間使ったときの消費電力量) utility-scale 電力供給に使う規模の hydro utility company t storage 貯蔵 (ここでは電気を蓄えておくことを意味する) grid solar installation a plot of land 一画の土地 land-line 地上 (の電話) 線 by a factor of two (増減の幅が)2倍で (50pts.) leapfrog 〜を一足跳びにする
