GWD10-Q10-Q13
One proposal for preserving
rain forests is to
promote the adoption of
Line new agricultural technolo-
(5) gies , such as improved
plant varieties and use of
chemical herbicides, which
would increase productivity
and slow deforestation by
(10) reducing demand for new
cropland . Studies have
shown that farmers in
developing countries who
have achieved certain levels
(15) of education, wealth, and
security of land tenure are
more likely to adopt such
technologies. But these
studies have focused on
(20) villages with limited land
that are tied to a market
economy rather than on
the relatively isolated, self-
sufficient communities with
(25) ample land characteristic of
rain-forest regions. A recent
study of the Tawahka people
of the Honduran rain forest
found that farmers with some
(30) formal education were more
likely to adopt improved plant
varieties but less likely to
use chemical herbicides
and that those who spoke
(35) Spanish (the language of
the market economy) were
more likely to adopt both
technologies. Nonland
wealth was also associated
(40) with more adoption of both
technologies, but availability
of uncultivated land reduced
the incentive to employ the
productivity-enhancing tech-
(45) nologies. Researchers
also measured land-tenure
security: in Tawahka
society, kinship ties are a
more important indicator of
(50) this than are legal property
rights, so researchers
measured it by a household’s
duration of residence
in its village . They found
(55) that longer residence correlated
with more adoption
of improved plant varieties
but less adoption of
chemical herbicides.
我的问题是这样的，我不是很明白这篇文章里面讲的几个比较（谁比谁更容易接受Plant varieties之类之类），能不能帮忙画个逻辑简图。
The primary purpose of the passage is to
A. evaluate the likelihood that a particular proposal, if implemented, would ultimately succeed in achieving its intended result
B. question the assumption that certain technological innovations are the most effective means of realizing a particular environmental objective
C. discuss the progress of efforts to encourage a particular traditional society to adopt certain modern agricultural methods
D. present the results of new research suggesting that previous findings concerning one set of conditions may not be generalizable to another set of conditions
E. weigh the relative importance of three factors in determining whether a particular strategy will be successful
这一题我选了E，答案是D，我不是很理解
The passage suggests that in the study mentioned in line 27 the method for gathering information about security of land tenure reflects which of the following pairs of assumptions about Tawahka society?
A. The security of a household’s land tenure depends on the strength of that household’s kinship ties, and the duration of a household’s residence in its village is an indication of the strength of that household’s kinship ties.
B. The ample availability of land makes security of land tenure unimportant, and the lack of a need for secure land tenure has made the concept of legal property rights unnecessary.
C. The strength of a household’s kinship ties is a more reliable indicator of that household’s receptivity to new agricultural technologies than is its quantity of nonland wealth, and the duration of a household’s residence in its village is a more reliable indicator of that household’s security of land tenure than is the strength of its kinship ties.
D. Security of land tenure based on kinship ties tends to make farmers more receptive to the use of improved plant varieties, and security of land tenure based on long duration of residence in a village tends to make farmers more receptive to the use of chemical herbicides.
E. 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, and a household is more likely to uphold the tradition of land tenure based on kinship ties if it possesses a significant degree of nonland wealth.
这一题更是云里雾里，我选了C，答案是A
 唉。。。我阅读好差。求帮忙 |
