gwd 10－10

      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

(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.

Q1: (10-10)

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

why D? someone explain it for me?  3x

D is right.

please check in the article, the author have mentioned many times "studies have shown ..." in line 11, 29, ... but  I did not find any asssumption, evaluation,  nor did i see any progressess and importance mentioned in the given information. so I choose D.

by the way, what is opinion to the q13, the answer is D. i could not understand very well.

Even this article is not too long, but the questions and choices are very confused. I  made all the wrong choices in my first-time exercise.  

got it,I haven't checked the artical more carefully

To your question:

Q4: (10-13)

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.

we are told in line 41-45:

" but availability of uncultivated land reduced the incentive to employ the productivity-enhancing tech-nologies"

and in line 4-11 we are told :

"new agricultural technolo- gies, such as improved plant varieties and use of chemical herbicides, which would increase productivity and slow deforestation by reducing demand for new cropland."

so choice D is right

确实非常的tricky,我第一遍看选E，第二遍选B，郁闷S了，后来，才狠狠地看了文章好几遍。才发现D答案，样子虽然少见，但确是答案。。。

我想说的是，这题的难点在于，（1）多个条件相互交叉，呈矩阵形，非常容易混；（2）这题的12、13两问的题目给出的定位行号肯定有问题。两题都一样，而且27行并不是一个开头的句子。

這題的主題題實在不好掌握

我第一次做選E

後來覺得A也不錯.....
很難去排除答案

這篇作者的目的到底是什麼??????????                                    Answer

我想，如果让我来解决这个问题，我就再把文章从作者目的的角度，一句句地看上几遍。

当然，我是希望楼上能够多深入看看文章，多想想。这样比较有益。

这篇文章是比较乱。

不乱，选D，定位38～45，“Nonland...,but availability of uncultivated land reduced the incentive to employ the productivity-enhancing technologies.”

10-10 why not a?

evaluate the likelihood that a particular proposal, if implemented, would ultimately succeed in achieving its intended result

intended result :protect rain forest
