问题     The shorter growing seasons expected with climate change over the next 40 years will endanger hundreds of millions of already poor people in the global tropics, say researchers working【C1】________the world’s leading agricultural organisations.
    The effects of climate change are likely to be seen across the entire tropical【C2】________but many areas previously considered to be【C3】________food secure are likely to become highly【C4】________to droughts, extreme weather and higher temperatures, say the researchers with the Consultative Group on International Agricultural Research.
    Intensively farmed areas【C5】________northeast Brazil and Mexico are likely to see their【C6】________growing seasons fall below 120 days, which is critical for crops【C7】________corn to mature. Many other places in Latin America are likely to【C8】________temperatures that are too hot for bean【C9】________, a staple in the region.
    The impact could be【C10】________most in India and southeast Asia. More than 300 million people in south Asia are likely to be affected even with a 5% decrease in the【C11】________of the growing season.
    Higher peak temperatures are also expected to take a heavy【C12】________on food producers. Today there are 56 million crop-dependent people in parts of west Africa and India who live in areas where, in 40 years, maximum daily temperatures could be【C13】________than 30℃ . This is【C14】________to the maximum temperature that beans can tolerate,【C15】________corn and rice yields suffer when temperatures【C16】________this level.
    "We are starting to see much more clearly【C17】________the effects of climate change on agriculture could【C18】________hunger and poverty," said research leader Parti Kristjanson. "Farmers already【C19】________variable weather by changing their planting schedules. What this study suggests is that the speed of climate【C20】________and the magnitude of the changes required to adapt could be much greater."
【C3】

选项 A、precisely
B、relatively
C、gradually
D、magically

答案B

解析 语义逻辑题。此空所在的分句大意为许多原先被认为安全(secure)的粮区如今可能如何如何,暗含一种往昔对比,从后面的droughts,extreme weather和higher temperatures可推测,这些粮区如今的情况应该不乐观,即前面所说的“安全”只是相对而言的安全,故选B项relatively“相对地”。A项precisely“精确地”填入文中为precisely food secure“精确安全的粮区”,过于绝对,与后面的droughts和extreme weather相矛盾。C项gradually“逐渐地”和D项magically“如魔法般地”皆不能体现句中暗含的对比关系。
