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.

文章结构层次划分: 

结构:Proposal:新技术,改良植物品种+采用化学除草剂 → 提高生产率,减少森林砍伐 

①农民(education,wealth,security of land tenure)→采用新技术 

②研究仅限于土地有限的村庄 

③受教育的农民:改良的植物品种 

④Noland财富:两种技术 

⑤土地使用权保障:

kinship ties→ land tenure

Residence→land tenure

⑥residence→ improved plant varieties 



第1题    答案:A

根据题干定位到文章第⑤⑥层次,通过分析第⑤层次一共有两条逻辑链,kinship ties→ land tenure ;Residence→land tenure,而residence的时间长短又暗示kinship ties的强弱,所以这三者之间是有逻辑关系,从最简单粗暴的角度理解,只有A选项讲了这三个因素两两之间的相互关系,所以选A。再深入探讨,题干中问的是security of land tenure反映了下面哪两组前提,文章指出kinship ties are a more important indicator of land tenure,所以前提是land tenure取决于kinship ties的强弱;文章又指出researchers measured land tenure by a household‘s duration of residence in its village,所以前提是duration要影响land tenure,从而与kinship ties相关。所以这道题选A。 B选项The ample availability of land makes security of land tenure unimportant文章未提及。C选项,kinship ties is a more reliable indicator than is its quantity of Nonland wealth,无关比较。D选项,more receptive to the use of chemical herbicides与文意不符,应该是更倾向于使用improved plant varieties,从文章最后一句可得到。E选项,A household is more likely to be receptive to the concept of land tenure based on legal property rights if it has easy access to uncultivated land,文章未提及。
