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

When I was invited to an 次の英文を3分15秒で読んで, 1. の問いに答えなさい。 American woman's house for Christmas, her mother said to me, "We usually don't have a regular breakfast. Will you need breakfast tomorrow?" Out of reserve, I was not able to say "Yes, I will," because (1)that would require her to prepare breakfast for me 5 alone. I had no choice but to say, "No, thank you. (2)Her mother took me at my word, and assumed that I was also in the habit of skipping breakfast. When I was back at the university after the holidays, I (3)brought up the subject with a few Americans. 4)"If you had been in my place, and had needed breakfast, what would you have said?" One person said, "Your friend's mother was being frank, so I'd 00.00% 10 have said frankly, 'If you could prepare a little breakfast, I'm sure I'd enjoy it. (5) Otherwise, I'll eat out." Another person said, "That's not so polite. I'd have asked her politely, 'If you could prepare breakfast for me, I'd appreciate it." They asked me why I had been reluctant to give a frank opinion. I explained the Japanese cultural viewpoint. In Japan, immediately accepting an 15 offer of a meal is regarded as impudent; such an invitation is supposed to be declined at least once. But the host realizes that the guest has declined out of reserve, and makes it a rule to ask a second time. A Japanese guest never insists on being served a meal. The host understands the situation and the feelings of the guest and reacts appropriately. (7) "That idea has no chance at all of working here," one American said with total frankness. She continued, "Unless you're frank here, you'll go hungry all the time."
