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

V People fly for all sorts of reasons, which means their moods, their expectations, and their baggage will differ greatly. These days, with air travel A due to the global COVID-19 pandemic, the simple act of flying has taken on a whole different character with new rules and questions about existing policies (like whether you can bring food on a plane). Flight attendants are experts on every aspect of air travel. They know B to look for, what sets off alarm bells and C to handle a variety of situations at a moment's notice As soon as you step onto the plane, you can bet that they're making some quick observations - it's one of the things your flight attendant won't tell you.)

「,well behind 」の部分の構造、意味を教えてください。

[Review] Back in the late sixties, thinkers on both sides of the Atlantic were troubled by problems which may seem strange to us today: they were worried that the leisure age which they believed was fast approaching would leave people with too much time on their hands. They were worried that the work ethic was losing its grip on a new rebellious generation and they pondered how they would motivate people to work. They needn't have worried. The much-predicted "leisure age" promised by technology has not materialized. In fact, quite the reverse: people are working harder than ever. There is less leisure time and, most surprising of all, the very workers with the greatest bargaining power are choosing to work the hardest. The problem is the burnout of white- collar Britain. For over a century, the average number of hours spent working over a lifetime slowly declined in Britain. The historian James Arrowsmith has calculated that in 1856 our ancestors put in 124,000 hours over a 40-year working life and, by 1981, it was 69,000. There it remained for a decade, but in the early nineties it began to increase again. On average full-time British workers now put in 80,224 hours over their working life, and that figure rises to 92,000 for those on a 50-hour week, which is common among the self- employed, the skilled, and professional and managerial workers. Many are working the kind of hours that would have been familiar to factory workers in the middle of the 19th century. The only difference is that now it's the bosses who are more likely to be putting in the hours than those on the shop floor. Britain has followed a US model of all work, no play, in contrast to continental Europe. Full-time workers in Britain now work the longest hours in Europe an average of 43.6 hours per week compared with an EU average of 40.3. Even more marked is the difference in holidays between Britain and continental Europe; the UK has, on average, 28 days a year, well behind France with 47, Italy with 44 and Germany with 41. Add the difference in weekly hours and holidays and it amounts to the British working almost eight weeks a year more than their European counterparts. -

(1). For more than a quarter-century, scientists and the general public have been updating view of the Americas before European contact. For example, they've found that the plains faolo s and the Eastern forests were not a wilderness but a series of gardens. The continents were not vast uninhabited spaces but a busy network of towns and cities. Indigenous people,* we've 05 learned, altered the ecology of the Americas as surely as the European invaders did. Now, there is a comprehensive new study bearing the names of more than 40 researchers. It suggests that marks left by humans can even be seen across one of the most biodiverse* yet unexplored regions in the world, the Amazon rainforest. For more than 8,000 years, people lived in the Amazon and farmed it to make it more o productive. (2) They favored certain trees (over others effectively creating crops that we now call the cocoa bean and the Brazil nut, and eventually domesticated them. While many of the communities managing these plants) died in the Amerindian genocide* 500 years ago, the effects of their work can still be observed in today's Amazon rainforest. "People arrived in the Amazon at least 10,000 years ago, and they started to use the species that were there. And, cted plants with specific physical traits that are useful for JOOBOTS 31
