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

humans. "We were able to identify one of the many molecular features that likely shape behavior," she adds. ** hol boquete es Though the origins of the dog/human partnership remain unknown, it's becoming increasingly clear that each species has changed (during our long years header The physical differences between a basset hound and wolf are obvious, but dogs have also changed in ways that are more than skin (or fur) deep. One recent study shows how by bonding with us and learning to work ogether with humans, dogs may have actually become worse at working together Their pack lifestyle and mentality appear to be reduced and are far as a species. less prevalent even in wild dogs than in wolves. But, Yale's Laurie Santos says, dogs may have compensated in other interesting ways. They've learned to use humans to solve problems. "Several researchers have presented dogs and wolves with an impossible problem (e.g., a puzzle box that can't be opened or a pulling tool that stops working) and have asked how these different species react," Santos explains. Researchers have found that wolves try lots of different trial and error tactics to solve the problem - they get at it physically. But at the first sign of trouble, dogs do something different. They look back to their human companion for help. This work hints that dogs may have lost some of their physical problem-solving abilities in favor of more social strategies, ones that rely on the unique sort of cooperation

第3・4段落 1So how do we reconcile our economy with ecology? The Earth provides us with essential natural services like air and water purification and climate stability, but these aren't part of our economy because we've always assumed such things are free. 3But natural services are only free when the ecosystems that maintain them are healthy. 4Today, with our growing population and increasing demands on ecosystems, we're degrading them more and more. Unfortunately, remedial activities and products like air filters, bottled water, eye drops and other things we need to combat degraded services all add to the GDP, which economists call growth. Something is terribly wrong with our economic system when poor environmental health and reduced quality of life are actually good for the economy! 「それでは,私たちはどのようにして経済と環境の折り合いをつけるのだろうか。 地球は空 気や水の浄化、気候の安定性といった必要不可欠な自然のサービスを提供してくれるが,私た ちはこれまでずっとそういうものは無料だと思い込んでいたので,それらは経済の一部とはな っていない。 しかし、自然のサービスが無料なのは, それを維持する生態系が健全なときだけなのであ る。 4今日,人口が増加し生態系への負担が高まるにつれ,私たちは生態系をますます傷つけて いる。 5残念なことに, 環境改善のための活動や製品,たとえばエアフィルター, ボトル入りの 水,目薬や質が低下したサービスに対処するために私たちが必要とするその他のものはすべ て GDPを増加させるが, それを経済学者は成長と呼ぶ。 環境が不健全になり、生活の質が低 下していることが実は経済にとってよいことなら、私たちの経済システムは何かがひどく間違 っているのである。 □ecology 「環境,生態」 2□essential 「必要不可欠な」 □ stability 「安定性」 30ecosystem 「生態系｣ 4 demand on A 「A への要求, 負担」 □ purification 「浄化」 □ climate 「気候｣ □ free 「無料の」 | degrade 「を悪化させる, の質を低下させる」 99

マーカーの部分ってどのように訳すのが正しいんですか？💦

The Environmental Protection Agency (EPA) plans to update rules that would reduce lead in drinking water. The agency says it will require utility companies to replace old lead water pipes. The current rules are decades old. They have failed to prevent crises in Washington, D.C.; Flint, Michigan; and other communities where many people have had lead in their drinking water.

次の英文を読んで, 設問に答えなさい。 25 min. 454 words 2 25分ぐ終了 ( Listening to a gardening program the other day, I was struck by something the /S-70₂ expert said about a particular type of potted plant. Do not water it once it has *come into bud, he advised. Cause it to feel stress, and it will produce more, and more beautiful, flowers. 52 Surely this advice is against everything that we are told by doctors. Stress is bad for us, they say. Stress is the cause of all sorts of diseases. Stress caused by overwork sometimes results in early death. Newspaper and magazine articles tell us how to reduce stress, or how to avoid it altogether. No one has a good word for stress. 10 3 And yet, I asked myself, if stress is good for plants, can there possibly be any value for us in it? The longer I thought about it, the more it seemed to me that there is. Without a certain degree of tension and stress, we are apt to become lazy and neglect our duties. All students know that they should study regularly throughout the year, and then be able to face examinations without fear. In fact, 15 most students leave this study till the last possible moment, and then hastily try to ( 3 ) lost time. Many of us, likewise, put off dealing with our problems until the deadline approaches. Every year I resolve that I will write all my Christmas cards and letters ahead of time, and avoid a last-minute rush; and every year I find that 20 once again I have left it too late for me to finish comfortably. Only when the tension increases [working seriously / the job / do / to get/I/done / start]. (4) In other fields too, when satisfaction enters in, creativity and curiosity go out of the window. What has been called "divine discontent" - a creative dissatisfaction (5) with the present situation, whatever it is produces progress. And that 25 dissatisfaction is one type of stress. 6Thus, it seemed to me, a certain degree of stress is necessary for human progress. Just how much is good, and how much is harmful, is the problem. Those of us who are employed by a company/whose policies demand long periods of stressful activity/are to be sympathized with, since too much stress is activity/are
