13 Lucy is a British schoolgirl who lives in Oxford. She is talking to her father, Fred, in the kitchen of their home. Read the conversation below and answer the following questions. Lucy: (a) Good morning, Dad. Oh, sorry for yawning. What are you doing with that microwave oven? It looks heavy. Do you need a hand with moving it? Fred: I think I'll be OK, Lucy. I'm just going to put it in the car and take it to the city dump. Lucy: Couldn't you send it away to be repaired? Fred: It's ten years old and well out of warranty now, so I very much doubt that the manufacturer would do it. They probably don't even carry the spare parts anymore. Lucy: That's a shame. Oh, I know what! Why not take it to the Repair Café near my school? Fred: What's that? I've never heard of it. Lucy: It's brilliant! We visited it as part of our environmental science course recently. It's a meeting place where people can get together to mend broken items cooperatively. And have a chat and a cup of coffee! Fred: I'm all ears. Tell me more. Lucy: Well, the first Repair Café was started by a Dutch woman called Martine Postma in Amsterdam in 2009. (1) 彼女は,使い捨て文化で環境が破壊されて, ゴミの量が地球規模で増えることを心配してたん . She wanted to find a local solution to this global problem. Fred: That's what they call "thinking globally, acting locally," isn't it? Lucy: Exactly. She also wanted to address the decline in community spirit amongst urban dwellers and do something about people's loss of practical skills and ingenuity. Fred: And the idea (2) caught on? Lucy: Very much so. The concept has grown into a global movement. The one in Oxford started about four years ago. Fred: Impressive! What kind of things do they repair? Lucy: Oh, all sorts. Electrical appliances, clothes, furniture, crockery, bicycles, and even toys. Fred: How successful are they at repairing things? Lucy: Well, of course, they cannot guarantee to fix every item brought to them, but they have a fairly good success rate. One study found that on average 60 to 70 percent of items were repaired. The rate is higher for some items such as bicycles and clothes but lower for things like laptop computers. Fred: I can understand that. Just between you and me, I think some electronics manufacturers deliberately make products in such a way that you cannot disassemble them and repair them unless you have specialized tools and equipment. Lucy: Yes, and that's where Repair Cafés can help. But these cafés are not just about repairing things for people. They are places where we can meet others, share ideas, and be inspired. The volunteer repairers are very keen to involve the visitors in thinking about the repair and actually carrying out the repair themselves. They also encourage people to think about living together in more sustainable communities. Fred: I suppose you could say they are about repairing our minds, not just our things. Lucy: Quite so, although often the two are very closely related. Many people attach (3)sentimental value to old things that might, for example, be part of their family history. Fred: I see what you mean. It almost sounds too good to be true. (a)Is there a catch? For example, how much does it cost? Lucy: Advice and help from the repairers is free, but people who use the café are invited to make a donation. That money is used to cover the costs involved in running the café. If specific spare parts are needed, the repairers will advise you on how to obtain them. Fred: Well, that's marvelous! (e)Then I'll take this old microwave there. Are they open today? Lucy: Yes, and I'll come with you. I've got a pair of jeans that are badly in need of some attention. QUESTIONS 1. Translate the underlined part after (1) into English. 2. What does the underlined phrase after (2) mean? Select the most appropriate expression from the list below. (A) became popular (B) hit a dead end (C) occurred to you (D) played a significant role (E) worked in practice 3. The underlined phrase after (3) means the value of an object which is derived from personal or emotional association rather than its material worth. Give ONE object that has "sentimental value" for you and explain why it has such value. Your answer should be between 15 and 20 English words in length. (Indicate the number of words you have written at the end of your answer.)

次の英文を読み, 下記の設問に答えなさい。 There are few things on this planet that give me greater joy than making my home the most comfortable, relaxing place possible. So, one winter a few years ago, when my fiancé had a bout of insomnia, I sprang into action, gathering all the things that held promise for a great sleep: black-out curtains, a white noise machine, and the cult favorite a weighted blanket. Weighted blankets, which cost anywhere from $100 and up, are a sleep aid usually made in a duvet style, with the many squares throughout filled with heavy beads. Lovers of the weighted blanket claim that under its weight they can relax faster, leading to a better and deeper sleep. These blankets weigh anywhere from 5 to 14 kg, and manufacturers generally recommend choosing one that's not more than 10 percent of your body weight, although this seems to be just a rule of thumb and not based on scientific study. [1] "Absolutely love it," my friend Greg Malone tells me over Facebook one day. "Rotating shifts makes [a] to sleep hard, but my girlfriend got me one as a gift, and I have found it's made a big difference in falling and staying asleep.' However, Deep Pressure Therapy (DPT)— the act of using firm but gentle pressure on the body to reduce anxiety has been practiced for centuries in various forms. In 1987, a limited study found that many college students who used DPT reported feeling less anxious after [b] full-body pressure for 15 minutes (in an adorably titled "Hug'm Machine"), although the researchers did not note any physical changes like lowered heart rate or blood pressure that would indicate the participants were more relaxed. That being said, a 2016 study found that patients who used a weighted blanket while having their wisdom teeth removed tended to have a slower heart rate than (2)patients who underwent the procedure without, which may indicate that they were more relaxed. However, many patients didn't report feeling more relaxed, and since they each only went through the procedure once, it's difficult to tell if the weighted blanket was the key to calming down. 2 Some say that simply the fact that a weighted blanket makes it more difficult to toss and turn at night makes for a better night's sleep, while others claim it has something to do with [c] the blood vessels on the surface of our skin that causes our heart rate to slow down. It also could be that the feeling reminds us of times when we felt the safest, like getting a hug from someone who cares for us or when our parents would swaddle us as newborns. 3 Similar to how many people adore the feeling of a soft blanket against their skin or can't relax without their favorite scented candle burning, others might connect with the feeling of gentle, full- body pressure. The trick is finding the sensory cue that makes you the most comfortable. "Weighted blankets have been around for a long time, especially for kids with autism or behavioral disturbances," Dr. Cristina Cusin, an assistant professor of psychiatry at Harvard Medical School, told Harvard Health. "It is one of the sensory tools commonly used in psychiatric units. Patients who are in distress may choose different types of sensory activities holding a cold object, [d] particular aromas, manipulating dough, building objects, doing arts and crafts - to try to calm down." My fiancé immediately disliked the 9-kg blanket I had picked up and said it made him feel like he was trapped. He's not alone in (3) this. "I liked it at first, but then as the night went on, I felt trapped," Heather Eickmann, a family friend, told me. "Also, I sleep on my side, and it really started to make my hip and knee joints ache." With the weighted blanket making my partner's sleep worse, I decided to give it a try myself. And (4) while I didn't find it too heavy to curl up under, the 9-kg blanket did turn making the bed into a small strength exercise. Overall, I tend to be a good sleeper, so swapping out blankets didn't make any outstanding differences to the quality of my snooze. However, later that summer, (5) ² を使ってみたら, まったく別の理由で夜中に目をさましているのに気づいた。 The blanket was HOT. [ Jones, Emma. "Can Weighted Blankets Help You Sleep Better?"

次の英文を読み、 下記の設問 (A~D) に答えなさい。 In the last few decades, people all over the world have been told that humankind is on the path to equality, and that globalization and new technologies will help us get there sooner) In reality, the twenty- first century might create the most unequal societies in history. Though globalization and the Internet bridge the gap between countries, they threaten to enlarge the gap between classes, and just as humankind seems about to achieve global unification, the species itself might divide into different biological types. Inequality goes back to the Stone Age. Thirty thousand years ago, hunter-gatherer tribes buried some members in grand graves filled with thousands of ivory beads, bracelets, jewels and art objects, while other members had to (7)settle for a mere hole in the ground. ( 1), ancient hunter-gatherer tribes were still more egalitarian* than any succeeding human society, because they had very little property. Property is a condition for long-term inequality. Following the Agricultural Revolution, property multiplied, and with it inequality. As humans gained ownership of land, animals, plants and tools, hierarchical** societies emerged, in which small elites monopolized wealth and power for generation (2) generation. Hierarchy, then, came to be recognized not just as the model, but also as the ideal. How can there be order without a clear hierarchy between elites and ordinary people, between men and women, or between parents and children? Authorities all over the world patiently explained that just as in the human body not all parts are equal, so also in human society equality will bring nothing (3) disorder. In the late modern era, however, equality became an ideal in almost all human societies. It was mainly due to the Industrial Revolution, which made the masses more important than ever before. Industrial economies relied on masses of common workers, (4) industrial armies relied on masses of common soldiers. Governments invested heavily in the health, education and welfare of the masses, because they needed millions of healthy workers to operate the production lines and millions of loyal soldiers to fight in the wars. with ti own no (3) of sup horizo partic again A. Consequently, the history of the twentieth century revolved around the ( 5 ) of inequality between classes, races and genders. Though the world of the year 2000 still had its share of hierarchies, it was かなり nevertheless a much more equal place than the world of 1900. In the first years of the twenty-first century people expected that the egalitarian process would continue and even speed up. In particular, they hoped that globalization would spread economic growth throughout the world, and that as a result people in India and Egypt would come to enjoy the same opportunities and privileges as people in Finland and Canada. An entire generation grew up on this hope. Now it seems that this hope might not be fulfilled. Globalization has certainly profited large portions of humanity, but there are signs of growing inequality both between and within societies. Some groups increasingly monopolize the fruits of globalization, while billions are left behind. Already today, the richest hundred people together own more than the poorest four billion. This could get (6) worse. The rise of Al (Artificial Intelligence) might eliminate the economic value and political power of most humans. At the same time, improvements in biotechnology might make it possible to translate economic inequality into biological inequality. Soon the super rich might be able to buy life itself. If new treatments for extending life and for upgrading physical and intellectual abilities prove to be expensive, a huge biological gap might open up between the rich and the poor. By 2100, the rich might be more talented, more creative and more intelligent than the less advantaged. Once a real gap in ability opens between the rich and the poor, it will become almost impossible to close it. If the rich use their superior abilities to enrich themselves further, and if more money can buy them more efficient bodies and brains, B B V
