单选题It was late on an August afternoon, the air hot and heavy like it usually was in the rainy season. Earlier we'd seen some thunderheads near the Burnt Spring Hills, but they'd passed way up to the north. I'd mostly finished my chores for the day and was heading down to the pasture with my brother, Buster, and my sister, Helen, to bring the cows in for their milking. But when we got there, those girls were acting all bothered. Instead of milling around at the gate, like they usually did at milking time, they were standing stiff-legged and straight-tailed, twitching their heads around, listening. Buster and Helen looked up at me, and without a word, I knelt down and pressed my ear to the hard-packed dirt. There was a rumbling, so faint and low that you felt it more than you heard it. Then I knew what the cows knew—a flash flood was coming. I figured we best bolt, too, so I grabbed Helen and Buster by the hand. By then I could feel the ground rumbling through my shoes. I saw the first water sluicing through the lowest part of the pasture, and I knew we didn't have time to make it to higher ground ourselves. In the middle of the field was an old cottonwood tree, broad-branched and gnarled, and we ran for that. Helen stumbled, so Buster grabbed her other hand, and we lifted her off the ground and carried her between us as we ran. When we reached the cottonwood, I pushed Buster up to the lowest branch, and he pulled Helen into the tree behind him. I shimmied up and wrapped my arms around Helen just as a wall of water, about six feet high and pushing rocks and tree limbs in front of it, slammed into the cottonwood, dousing all three of us. The tree shuddered and bent over so far that you could hear wood cracking, and some lower branches were torn off. I feared it might be uprooted, but the cottonwood held fast and so did we, our arms locked as a great rush of caramel-colored water, filled with bits of wood and the occasional matted gopher and tangle of snakes, surged beneath us, spreading out across the lowland and seeking its level. We just sat there in that cottonwood tree watching for about an hour. The sun started to set over the Burnt Spring Hills, turning the high clouds crimson and sending long purple shadows eastward. The water was still flowing beneath us, and Helen said her arms were getting tired. She was only seven and was afraid she couldn't hold on much longer. Buster, who was nine, was perched up in the big fork of the tree. I was ten, the oldest, and I took charge, telling Buster to trade places with Helen so she could sit upright without having to cling too hard. A little while later, it got dark, but a bright moon came out and we could see just fine. From time to time we all switched places so no one's arms would wear out. The bark was chafing my thighs, and Helen's, too. About halfway through the night, Helen's voice started getting weak. "I can't hold on any longer," she said. "Yes, you can," I told her. "You can because you have to. " We were going to make it, I told them. I knew we would make it because I could see it in my mind. I could see us walking up the hill to the house tomorrow morning, and I could see Mom and Dad running out. It would happen—but it was up to us to make it happen. To keep Helen and Buster from drifting off to sleep and falling out of the cottonwood, I grilled them on their multiplication tables. When we'd run through those, I went on to presidents and state capitals, then word definitions, word rhymes, and whatever else I could come up with, snapping at them if their voices faltered, and that was how I kept Helen and Buster awake through the night. By first light, you could see that the water still covered the ground. In most places, a flash flood drained away after a couple of hours, but the pasture was in bottomland near the river, and sometimes the water remained for days. But it had stopped moving and had begun seeping down through the sinkholes and mudflats. "We made it," I said. I figured it would be safe to wade through the water, so we scrambled out of the cottonwood tree. We were so stiff from holding on all night that our joints could scarcely move, and the mud kept sucking at our shoes, but we got to dry land as the sun was coming up and climbed the hill to the house just the way I had seen it.

单选题The food you eat does more than provide energy. It can have a dramatic effect on your body's ability to fight off heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones. With remarkable consistency, recent research has found that a diet high in plant-based foods--fruits, vegetables, dried peas and beans, grains, and starchy staples such as potatoes is the body's best weapon in thwarting many health-related problems. These foods work against so many diseases that the same healthy ingredients you might use to protect your heart or ward off cancer will also benefit your intestinal tract and bones. Scientists have recently estimated that approximately 30 to 40 percent of all cancers could be averted if people ate more fruits, vegetables, and plant-based foods and minimized high-fat, high-calorie edibles that have scant nutritional value. Up to 70 percent of cancers might be eliminated if people also stopped smoking, exercised regularly, and controlled their weight. In the past, researchers had linked fat consumption with the development of cancers, but they currently believe that eating fruits, vegetables, and grains may be more important in preventing the disease than not eating fat. "The evidence about a high-fat diet and cancer seemed a lot stronger several years ago than it does now," says Melanie Polk, a registered dietitian and director of nutrition education at the American Institute for Cancer Research. The road to strong bones is paved with calcium-rich food. Leafy green vegetables and low-fat dairy products are excellent sources of calcium, the mineral that puts stiffness into your skeletal system and keeps your bones from turning rubbery and fragile. Your body uses calcium for more than keeping your bones strong. Calcium permits cells to divide, regulates muscle contraction and relaxation, and plays an important role in the movement of protein and nutrients inside cells. If you don't absorb enough from what you eat to satisfy these requirements, your body will take it from your bones. Because your body doesn't produce this essential mineral, you must continually replenish the supply. Even though the recommended daily amount is 1,200 mg, most adults don't eat more than 500 mg. One reason may have been the perception that calcium-rich dairy products were also loaded with calories. "In the past, women, in particular, worried that dairy products were high in calories," says Letha Y. Griffin, M.D. , of Peachtree Orthopaedics in Atlanta. "But today you can get calcium without eating any high-fat or high-calorie foods by choosing skim milk or low-fat yogurt. " Also, low-fat dairy products contain phosphorous and magnesium and are generally fortified with vitamin D, all of which help your body absorb and use calcium. If you find it difficult to include enough calcium in your diet, ask your doctor about supplements. They're a potent way to get calcium as well as vitamin D and other minerals. But if you rely on pills instead of a calcium-rich diet, you won't benefit from the other nutrients that food provides. Getting the recommended vitamin D may be easy, since your body makes the vitamin when your skin is exposed to the sun's rays.

单选题I remember the way the light touched her hair. She turned her head, and our eyes met, a momentary awareness in that raucous fifth grade classroom. I felt as though I"d been struck a blow under the heart. Thus began my first love affair. Her name was Rachel, and I mooned my way through the grade and high school, stricken at the mere sight of her, tongue-tied in her presence. Does anyone, anymore, linger in the shadows of evening, drawn by the pale light of a window—her window—like some hapless summer insect? That delirious swooning, asexual but urgent and obsessive, that made me awkward and my voice crack, is like some impossible dream now. I would catch sight of her, walking down an aisle of trees to or from school, and I"d become paralyzed. She always seemed so poised, so self-possessed. At home, I"d relive each encounter, writhing at the thought of my inadequacies. We eventually got acquainted and socialized as we entered our adolescence, she knew I had a case on her, and I sensed her affectionate tolerance for me. "Going steady" implied a maturity we still lacked. Her Orthodox Jewish upbringing and my own Catholic scruples imposed an inhibited grace that made even kissing a distant prospect, however fervently desired. I managed to hold her once at a dance—chaperoned, of course. Our embrace made her giggle, a sound so trusting that I hated myself for what I"d been thinking. At any rate, my love for Rachel remained unrequited. We graduated from high school, she went on to college, and I joined the Army. When World War II engulfed us, I was sent overseas. For a time we corresponded, and her letters were the highlight of those grinding endless years. Once she sent me a snapshot of herself in a bathing suit, which drove me to the wildest of fantasies. I mentioned the possibility of marriage in my nest letter, and almost immediately her replies became less frequent, less personal. Her Dear John letter finally caught up with me while I was awaiting discharge. She gently explained the impossibility of a marriage between us. Looking back on it, I must have recovered rather quickly, although for the first few months I believed I didn"t want to live. Like Rachel, I found someone else, whom I learned to love with a deep and permanent commitment that has lasted to this day.
