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.

    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℃.

    "We are starting to see much more clearly【C17】______the effects of climate change on agriculture could【C18】______hunger and poverty," said research leader Patti 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."
【C6】

选项 A、grim
B、prime
C、slim
D、extreme

答案B
