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.

According to the passage, the proposal mentioned in line 1 is aimed at preserving rain forests by encouraging farmers in rain-forest regions to do each of the following EXCEPT

adopt new agricultural technologies grow improved plant varieties decrease their use of chemical herbicides increase their productivity reduce their need to clear new land for cultivation

文章大意逻辑
文章开篇提出保护雨林的一个提议是推广新农业技术，如改良植物品种和使用化学除草剂，这样能提高生产力，通过减少对新耕地的需求来减缓森林砍伐。接着阐述研究表明发展中国家达到一定教育、财富和土地保有权安全水平的农民更可能采用这些技术，且过往研究聚焦土地有限且与市场经济挂钩的村庄。然后以洪都拉斯雨林的塔瓦卡人研究为例，说明有一定正规教育的农民更可能采用改良植物品种，说西班牙语（市场经济语言）的农民更可能采用两种技术，非土地财富与两种技术采用正相关，未开垦土地的可用性降低了采用提高生产力技术的积极性，还提到土地保有权安全的衡量方式及发现居住时间长与改良植物品种采用正相关、与化学除草剂采用负相关。 文章类型及逻辑简图
文章类型为总分结构。逻辑简图： Proposal: promote new agricultural technologies to preserve rain forests (increase productivity, slow deforestation) Studies: factors related to farmers' adoption of technologies (education, wealth, land tenure security) Case study (Tawahka people): details about adoption of technologies based on different factors 做题方法及问题类型
这是一道细节题，通过定位文章首句提出的提议相关内容，以及后文对提议中农业技术的阐述来解题。 选项分析
A选项：“adopt new agricultural technologies”，与文章提议中推广新农业技术相符，不符合“EXCEPT”要求，排除。 B选项：“grow improved plant varieties”，改良植物品种是新农业技术之一，符合提议内容，排除。 C选项：“decrease their use of chemical herbicides”，原文提议是使用化学除草剂，而非减少使用，符合题意，当选。 D选项：“increase their productivity”，提高生产力是推广新农业技术的目的之一，符合提议，排除。 E选项：“reduce their need to clear new land for cultivation”，通过提高生产力减少对新耕地需求，是提议的作用，符合提议，排除。
