〔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."
