Park is enormous in size and covers over 1.5 million hectares, and the Reserved Zone is another 260,000 hectares. The reserve is made up of 13 ecological areas, thanks to a range of altitude from 200 to 4,000 meters. As can be expected from a park of this scale, the amount of flora and fauna is breathtakingly enormous. There are no particular limits to the number of visitors to the Reserved Zone, but the costly expense to visit the place naturally curbs the number of visitors. 制限

A Makeover for Hoover Dam Hydropower has attracted increasing attention in recent years as a renewable type of clean energy. As long as a suitable water source is available, hydropower facilities are usually good investments, producing energy in a manner that generates far less air pollution and CO2 emissions than fossil fuels do. The most common way to generate hydropower is to trap water at a high elevation behind a dam so it can be released and used to spin turbines below, which, in turn, power electricity-producing generators. However, hydropower has its drawbacks. Droughts and increased water consumption have reduced the flow of many rivers. As rivers become shallower, the necessary volume of water for electricity difficult to maintain, and power supply and generation is dependability are negatively impacted. more Variability in water levels has particularly affected Hoover Dam, a mega-scale hydropower facility in the US state of Nevada. Built in the 1930s at enormous expense to control the frequently flooding Colorado River and maintain a water supply for farmland irrigation, the dam's hydropower capabilities were seen as a way to recover some of the costs of its construction over the long term. The dam's electricity-generating capacity, however, was challenged from the start by seasonal variability in water flow, and in recent years has been greatly reduced by droughts. Combining hydropower with other alternative energy sources, though, may offer a solution. Solar and wind plants can produce enormous amounts of electricity, but one serious downside is that the energy they produce is not available when there is little sun or wind. While conventional batteries can help with this issue, storing such tremendous volumes of electricity has long been a challenge. A recently proposed system for Hoover Dam could provide an answer, though. The plan suggests building a new pumping station that would be powered by both wind and solar. It would push water from the river back up to Hoover Dam, refilling the lake behind it. The water could be released anytime to power the dam's generators in order to reliably meet demand for electricity. Kelly Sanders, an engineering professor at the University of Southern California, is enthusiastic about the storage plan, saying, "We by the p replace fo solat als are st ons to the What is 1 Inst inves 2 WE dams 3 A neg sys 1 en

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

〔Ⅰ〕 次の英文を読み. 設問 1~21 に答えよ。 Sandy lives in an apartment so small that when she comes home from shopping, she has to decide what to move out to make room for her purchases. She struggles day-to-day to feed and clothe herself and her four-year-old daughter on money from freelance writing jobs and helping neighbors. (2) Her ex-husband has long since disappeared down some unknown highway, probably never to be heard from again. As often as not, her car decides it needs a day off and refuses to start. That means bicycling (weather permitting), walking or asking friends for a ride. 13 The things most Americans consider essential for survival- a television. microwave, big freezer and high-priced sneakers are far down Sandy's list of "maybe someday" items. (5) Nutritious food, warm clothing, an affordable apartment, student loan payments, books for her daughter, absolutely necessary medical care and an occasional movie eat up what little money there is to go around. Sandy has knocked ) more doors than she can recall, trying to find (7) a decent job, but there is always something that doesn't quite fit-too little experience or not the right kind, or hours that make child care impossible. Sandy's story is not unusual. Many single parents and older people struggle with our economic structure, falling into the gap between being truly self-sufficient and being poor enough that the government will provide assistance. What makes Sandy unusual is her outlook. "I don't have much in the way of stuff or the American dream," she told me with a genuine smile. "Does that bother you?" I asked. "Sometimes. When I see another little girl around my daughter's age who has nice clothes and toys, or who is riding around in a fancy car or living in a fine house, then I feel bad. Everyone wants to do well for their children." she replied. "But you're not angry?" "What's to be angry (9) and I have what is really important in life," she replied. "And what is that?" I asked. (10) "As I see it, no matter how much stuff you buy, no matter how much )? We aren't starving or freezing to death. (11) money you make. you really only get to keep three things in life." she said. "What do you mean by 'keep?" (12) "I mean that nobody can take these things away from you." "And what are these three things?" I asked. "One, your experiences: two, your true friends; and three, what you grow inside yourself." she told me without hesitation. (13) For Sandy, "experiences" don't come on a grand scale. They are so-called ordinary moments with her daughter, walks in the woods, napping under a shady tree, listening to music, taking a warm bath or baking bread. Her definition of friends is more expansive. "True friends are the ones (15) who never leave your heart, even if they leave your life for a while. Even after years apart. you pick up with them right where you left off, and even if they die, they're never dead in your heart," she explained. 16 ) to each of us. (17 As for what we grow inside, Sandy said, "That's ( isn't it? I don't grow anger or sorrow. I could if I wanted to, but I'd rather not." "So what do you grow?" I asked. Sandy looked warmly at her daughter and then back to me. She pointed toward her own eyes, which were shining with tenderness. gratitude and a sparkling joy. "I grow this."
