〔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."

(2)の訳は 「そのことについて考えれば考えるほどストレスには私たちにとって何かが価値があるように思われた」 なのですが、訳を書く時に「そのこと」と書くのは違和感があります。aboutの後ろのitはit=stressですよね? だとしたら「ストレスについて...」と書いても... Read More

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
