【正文】 oningly. Was I allergic to anything? What if I was? What would happen to me? My mother said no. That evening after taking my pill, I began to shake uncontrollably. I plained of a terrible headache and continued shaking as my mother held me. She didn‘t seem very concerned, yet I believed I was allergic to the pill. Before I fell asleep that night, I told my mom the medicine had made me sick and I wouldn‘t take it anymore. The next morning, my mother had me drink a tall glass of iced tea that tasted funny. Later that afternoon, my mom asked me how I felt. I told her I was doing much better, and that was when she dropped the bomb on me. She told me she had mixed my ice tea that morning with my medicine. Guess what, no allergic reaction. I was never allergic to the pills, but my powerful subconscious (潛意識(shí)的 ) mind, accepted a mere suggestion by the doctor that I might be, and my body acted accordingly. Most of us have no idea how powerful our minds are, and how ining information continually affects our experience. When I took that pill, it had a negative effect on my mind. Researchers are finding more and more evidence that what we believe, or expect to happen medically, has a deep effect on what actually does happen. In some medical trials, the patients never took any medicine, only sugar pills, but were told they had been given expensive medicine, and their conditions improved anyway. They simply believed they would get better. On the other side of the coin, people who believe they are going to die in an operation have a higher death rate than people who don‘t. What we expect often tends to get realized. The power of your mind to heal your body is absolutely fantastic. Take care in what information you choose to believe about your health and wellbeing. Think positively about your oute in medical situations and allow your power of belief to help you heal. 49. The girl shook uncontrollably that evening because she _______.

First, it now appears that we will have to double world food production in the next 40 years due to population growth, increasing meat consumption and pressure from biofuels (生物燃料 ). We will also have to reduce the environmental impacts from our farming practices, which have caused widespread damage to soils, ecosystems, waters and even the atmosphere. In fact, agriculture‘s impacts are as bad as climate change as an environmental concern. Besides, we will have to improve food security for the world‘s poor. While the Green Revolution of the 1960s made it possible to feed hundreds of millions more people than in earlier eras, the number of the undernourished in the world has started to rise again. Finally, we will have to increase the recovering ability of agriculture from shocks. Today, our highefficiency, globalized world has many benefits, but it is vulnerable (易受傷的 ) to destruction, whether from droughts, diseases or sudden price rises. We must start building better food systems to better keep us away from future shocks. Currently, there are two models of agriculture: local and anic agriculture vs. globalized and industrialized agriculture. Each has been strongly supported and severely criticized, but neither of these models, standing alone, can fully meet our needs. Organic agriculture teaches us important lessons about soils, nutrition and pest management. Unfortunately, anic food provides less than 1% of the world‘s calories, mostly to the wealthy. It is hard to imagine anic farming developing to feed 9 billion. Globalized and industrialized agriculture has benefits of high output and low labor demands. Without it, billions of people would have starved. However, it has e with enormous environmental and social costs, which cannot be sustained. Rather than voting for just one solution, we need a third way to solve the crisis. Let‘s take ideas from both sides, creating new, hybrid solutions that increase production, save resources and build a more sustainable agriculture. There are many promising avenues to pursue. A new ―third way‖ for agriculture is not only possible but also necessary. Our problems are huge, and they will require everyone at the table, working together toward solutions. 53.
