| GWD-10-Q10 to GWD-10-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, selfsufficient
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
17
(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.

GWD-10-Q13:
The findings of the study mentioned in line 27, if valid for rain-forest regions in general,
suggest that which of the following is an obstacle most likely to be faced by those
wishing to promote rain-forest preservation by implementing the proposal mentioned in
line 1?
A. Lack of legal property rights tends to discourage local farmers from investing the
time and resources required to successfully implement new agricultural
technologies.
B. The ability to evaluate the wider economic ramifications of adopting new
aricultural technologies depends on a relatively high level of formal education.
C. Isolation from the market economy tends to restrict local farmers’ access to new
agricultural technologies that could help them to increase their productivity.
D. Ready availability of uncultivated land tends to decrease local farmers’ incentive
to adopt new agricultural technologies that would reduce their need to clear new
land for cultivation.
E. Traditions of self-sufficiency and reliance on kinship ties tend to diminish local
farmers’ receptivity to new agricultural technologies introduced by people from
outside the local community.
答案：D。看不出原文那里表达了这个意思阿？还请NN指点！ 谢谢！ |
