One proposal for preserving rain forests is to promote the adoption of new agricultural technologies, such as improved plant varieties and use of chemical herbicides, which would increase productivity and slow deforestation by reducing demand for new cropland. Studies have shown that farmers in developing countries who have achieved certain levels of education, wealth, and security of land tenure are more likely to adopt such technologies. But these studies have focused on villages with limited land that are tied to a market economy rather than on the relatively isolated, self‐ sufficient communities with ample land characteristic of rain-forest regions. A recent study of the Tawahka people of the Honduran rain forest found that farmers with some formal education were more likely to adopt improved plant varieties but less likely to use chemical herbicides and that those who spoke Spanish (the language of the market economy) were more likely to adopt both technologies. Nonland wealth was also associated with more adoption of both technologies, but availability of uncultivated land reduced the incentive to employ the productivity‐enhancing technologies. Researchers also measured land-tenure security: in Tawahka society, kinship ties are a more important indicator of this than are legal property rights, so researchers measured it by a household’s duration of residence in its village. They found that longer residence correlated with more adoption of improved plant varieties but less adoption of chemical herbicides.

    题型:aimed at preserving rain forests by encouraging farmers in rain-forest regions to do 事实信息题
    注意陷阱:EXCEPT:就是原文没有提及的信息
    回文定位:One proposal for preserving rain forests is to promote the adoption of new agricultural technologies, such as improved plant varieties and use of chemical herbicides, which would increase productivity and slow deforestation by reducing demand for new cropland.
    
    选项通常是同义改写
    
    有the adoption of new agricultural technologies 对应选项A adopt new agricultural technologies
    
    有improved plant varieties 对应选项B grow improved plant varieties 
    
    有use of chemical herbicides 与C decrease their use of chemical herbicides相反,所以C错
    
    有increase productivity 对应选项D increase their productivity
    
    有slow deforestation 无对应选项
    
    有reducing demand for new cropland 无对应选项E reduce their need to clear new land for cultivation

    这是一道单一细节题,回到文章中定位到第一句就能得出选项。 ABDE均在第一句话中提出,C选项与文章逻辑相反,文章中提到的是采用新技术,包括use of chemical herbicides,所以应该是增加chemical herbicides的使用,而不是减少。
