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."
【C8】

选项 A、prolong
B、relieve
C、contract
D、experience

答案D

解析 语义逻辑题。空格处填入谓语动词,说明拉丁美洲其他很多地方与温度过热之间的关系。experience意为 “经历”,填入文中表示“拉丁美洲其他很多地方可能会遭遇酷热”,符合句意。A项prolong意为“拖延,拉长”,B项relieve意为“减轻,缓解”,自然界的温度一般不能简单地受人为操控。我们不能“拖延/拉长温度”或“减轻温度”,故排除这两项。C项contract作及物动词时表“使收缩;染上(疾病)”,我们不能缩小温度,也不会说染上高温,此外contract与句中的temperatures搭配,同样句意不通。
