虽然我知道D是正确的，可是还是不太清楚为什么E不对呢？Q33:
A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.
Which of the following is a consideration in favor of the company’s implementing its plan to develop the prototype?
Here, why E is wrong? I think probably farm labors who carry out other duties because of new machine will indeed reduce the labor costs.
Dizzy now, could any NN help me?
Thank you, Les!
But there seems no the reply I need...
usdream，不太明白你的问题。
原文是说公司想发展一种割草机，这种割草机是通过感光器和微处理器区别杂草和庄家的。同时发明者说这将大大减少劳动成本，因为它根本不再需要人工除草了。
问题问下面哪一条支持了公司发展这种机器。
D选项实际上是说了一个条件使得这种割草器具有实用价值。
E is out of scope.
The conclusion of the premises is about "weeding machine", and the subject of choice E is "farm labors".
E is out of scope.
The conclusion of the premises is about "weeding machine", and the subject of choice E is "farm labors".
我认为选E
题干问的是a consideration in favor of 。。。是说以下哪个选项也反映了一种赞同支持该计划的考虑。E选项认为除了题目中的降低劳动成本之外，还可以把人力时间花在别的事情上，所以支持。
D选项是说有某种技术可以使颜色差别看起来比较大从而技术可行。但我认为文中根本没有说颜色差别大小是很严重的问题，同时题目没有让大家质疑或是补充条件，而是假设文章讲的都是对的，所以我们无需考虑颜色差别大不大这个问题严重不严重之类的。该选项作为无关项排除。
我认为选E.
这题是﹙D﹚还是﹙E﹚，有NN或版主可以给定论吗?
原题啥地方说是收割季节？好像除草就是生长季节吧。
E肯定不对，E实际上是weaken的意思。
原题啥地方说是收割季节？好像除草就是生长季节吧。
E肯定不对，E实际上是weaken的意思。
同意！ Ｅ实际上说的是人有时间去除草，机器就可能没用了。

为什么会是weaken呢？没有看出有weaken的意思呀？
同意！ Ｅ实际上说的是人有时间去除草，机器就可能没用了。
E好像是说机器有用了，人才有时间去做别的农活吧。 虽然我知道D是正确的，可是还是不太清楚为什么E不对呢？

我原来想的和你是一样的。但是，现在觉得E这项对机器发明与否没影响。因为，E说的是工人不除草时，他会做别的事情。可是不管工人在不除草时做不做别的事情，在机器发明以后，工人就是不用除草了，就可以做别的事情。
不过，我好象表达的不是很清楚。
选D
E是weaken，工人除了除草还干别的事，就说明用了机器后，即使工人不用除草（即eliminate the need for manual weeding），他们还是要干别的事，这样就不能reduce labor costs
相反，如果有一个选项“工人除了除草不干别的事”，这个就应该是正确的了
open to discussion
E只是猜测
既然是猜测就说不好了
比如这些农民也可能去城市务工

puccamummy2005-11-3 1:13:00say是的。E是说：负责人工除草的农场作业者在作物成长季节里，当杂草不需要处理时，可以抽空出来做其他的工作。——这个选项不能说明什么东西。
我还是觉得E 有道理。既然在不出草的时候可以做别的工作，那末一旦及其发明之后，即使在以前他们应该除草的季节，他们现在也可以去做别的工作呀，因为除草机的发明代替了人工，所以reduce labor costs。
不知道是不是我想多了，还是急需牛人帮助。大家在讨论的时候认为D是正确的，我总觉得D只是一个技术的讨论，并没有支持结论reduce labor costs.

E应该是无关。工人干不干别的事跟机器没啥关系。
E错。有机器后工人干不干活，跟需不需要机器无关。机器解放人的劳动，有机器后，人可以干别的事，也可以什么都不做，去休闲。农民为何一定是干活的苦命？
我也选的E.。 我记得有一题：费费逻辑讲座6
21(p71-1). A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 tree to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibora's extinction.
Which of the following, if true, most seriously weakens the argument above?
(A) The drug made from ibora bark is dispensed to doctors from a central authority.
(B) The drug made from ibora bark is expensive to produce.
(C) The leaves of the ibora are used in a number of medical products.
(D) The ibora can be propagated from cuttings and grown under cultivation.
(E) The ibora generally grows in largely inaccessible places.
我选E. 我认为，d并未说嫁接繁殖的速度是否快过制药需求的速度。可是费说应选D. E把继续生产的前提堵死了，因此不对。
同样，本题D把机器是否能用的前提堵死了。
E错。有机器后工人干不干活，跟需不需要机器无关。机器解放人的劳动，有机器后，人可以干别的事，也可以什么都不做，去休闲。农民为何一定是干活的苦命？

不是很明这里所说的，最后说D把机器是否能用的前提堵死了，一开始又说E错，那到底这总结是赞成D还是E呢？
我考虑了一下
原文题干是labor cost
而E只是说可以腾出时间干别的事情，没有解释labor cost一定减少，比如要使用这种机器，起码要培训，人力成本要高，
就比如收费，纸票贵，计算机收费便宜，但是计算机培训成本
E錯,是弱化
該句只提出工人在weeding不需要時會作其他工作,不代表這工作會影響需要weeding時的效率
如果該句的not拿掉,會清楚表示作其他工作會影響效率,則機器的發明會降低工人的影響力,才會強化
D for sure
这个公司打算发展一种自动除草的机器. 这个机器利用shade of color 来分辨crop plants 和weeds. (可能疑问是: weeds和plants能否通过shade of color来分辨)
问in favor of the company’s implementing its plan (就是说那些选项可以去除implementation中的疑问, 比如我上面提的那个疑问)
D说通过基因选择可以便宜的使得plants of virtually any species 有 distinctive shade of color. 回答了我上面提出的疑问.
E 说那些哥们在非除草季节干别的农活. 有没有机器他们在非除草季节都干农活.
无关项.

这个新机器的目的是reduce labor costs by virtually eliminating the need for manual weeding 在D当中提到了be economically bred to，所以就选了D

同意!!
E错就错在“when extensive weeding is not necessary”这句话上，不需要大量除草的话，不管怎样都与论题无关了。
公司研发原型机只要考虑技术因素就好。题干已经对此做了限制
E无关
E好像是说机器有用了，人才有时间去做别的农活吧。 虽然我知道D是正确的，可是还是不太清楚为什么E不对呢？
那我们来仔细看一下E：
Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary
我翻译的是：负责手动收割庄稼的农民们，在生长期中那些没必要进行大规模割草的时间里，还有别的农活儿要做。
这么一看，E怎么可能是正确项呢……
各位对这个翻译怎么看：）
agree with tangzimo !
"when extensive weeding is not necessary" is the key point here!
E is irrelevant.
E.Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary
我觉得这个E明明就在说,负责锄草的人在不必须锄草的季节干其他的活去了,what if in season when extensive weeding is necessary?他们是不是会回来锄草?还是让机器干?没给出...原文说的是基本上用了机器就用不着人了,就是说必须锄草的季节里也不用人,但是E对推出这个结果是很鸡肋的,试问一个到底怎么样没给出的选项怎么能选呢?
D:
题目中机器的使用是建立在能分清COLOR的基础上,承认植物的COLOR可以被承认就等于证明机器被使用的可能性.
between weeds
of different species. 无关
支持选D
我的理解是这样，不知道对不对。
E.讲不用除草了能干别的事情。
而题目说因为不用除草，所以能节省成本。要加强就要讲能帮着除草。而不是其他方式能节省成本。
所以D更接近答案。
E错就错在“when extensive weeding is not necessary”这句话上，不需要大量除草的话，不管怎样都与论题无关了。
赞同
在草的生长季节，工人可以去干别的农活。假设没有机器的时候，工人这段时间是也可以去干其他的农活，相比有了机器，工人同样也是去干农活。相比之下，并没有因为多干了农活相对的成本降低。e是无关项
If the prototype development were successful, it greatly save the manual work for weeding and allow the farmers to carry out other farming activities.
Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.
Genetic success in coloring the plant assist the sensor of the weeding machine to distinguish the weeds from the crop thus increase the likelihood of weeding machine adoption.
Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.
This choice says that if weeds flourish, farmers have to spend much time on manual weeding. This argument does not strength the main idea that the adoption of weeding machine is more likely.
A. There is a considerable degree of variation in shade of color between weeds of different species.
（不同杂草的颜色不同，属于无关选项）
我开始也看错了。。以为是杂草和庄稼有差别
