完形填空
A. The culprit is climate change, caused by society's burning of fossil fuels. When it comes to global warming, farmers who are more attuned to weather patterns than most people—may be the proverbial canaries in the coalmine. The weather, of course, has never been exactly dependable—farmers have always been at the mercy of the vagaries of sun and rain. But general weather patterns have at least been broadly predictable, allowing farmers to know when to sow their seeds, when to transplant, when to harvest. As weather patterns become less reliable, growers will be tested to develop new rhythms and systems for growing crops. B. Most keyboard jockeys would die for the view from Orin Martin's office window: apple trees in blossom, lines of citrus, dozens of varieties of flowers and neat rows of peppers and potatoes. Martin is a farmer in Santa Cruz, Calif., where for the last 30 years he has been an instructor at the University of California's agro-ecology program, one of the nation's oldest organic agriculture curriculums. C. What all agriculture experts agree on is that farmers need to start preparing today for climate change. Growers ought to be thinking about what warmer temperatures, fluctuations in precipitation, and an increase in extreme weather events will mean for their farms, and how they can respond. 'This is change; it's not necessarily disaster,' says Grubinger. 'The disaster will come if people aren't prepared.' D. In recent years, however, something has been wrong in his idyllic setting. The weather is changing in strange ways. From New England to the Midwest to California, farmers and scientists are noticing that once-dependable weather patterns are shifting. E. Among farmers and researchers, there is disagreement about which types of growers climate change will impact most—large agribusiness growing operations, or smaller, family-run farms. Some agriculture industry observers say that the bigger farmers will have an advantage in coping with weather changes, as they will have more resources to switch to new crops. Others say that since family farms usually grow a wider range of crops, their biological diversity will make it easier to cope with whatever changes occur. F. There is a misconception that the scientific community is in a state of disagreement about global warming. In fact, there is virtually no serious disagreement on the central points. The misconception of disagreement is actually an illusion that has been deliberately fostered by oil & coal companies. These companies want to prevent any new policies that would interfere with their current business plans that rely on the massive unrestrained dumping of CO2 into the Earth atmosphere every day. G. Too much rain at the wrong time can make it difficult to plant or harvest crops. Above-average rainfall also contributes to fungi and insects that can dramatically reduce crop yields. Too much warmth is equally problematic. Some plants require a certain number of frost days each year in order to thrive the following spring. As temperatures warm, farmers may find themselves having to either shift to different crops or actually move their operations to new locales. Unreliable weather will make it harder for farmers to be as productive as we have come to expect. Order: 41 → 42 → 43 → 44 →E→ 45
【答案解析】上一段A项的分析中指出，天气变化对农民的影响主要表现在阳光和雨水(sun and rain)上，而G项具体谈到了阳光和雨水对农业的影响。可见A项的后半部分和G项衔接紧密，这种“问题—原因—影响—具体影响”的行文顺序很连贯。因此可以确定答案为G。假如没有看出来A、G项之间的衔接关系，难免会误选F项，而误选F项的原因是该项中的“oil & coal companies”和上一段中的“burning of fossil fuels”相对应。
