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，那末一旦机器发明之后，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。

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.

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?

    

    

    

    

1. There is a considerable degree of variation in shade of color between weeds of different species.
2. The shade of color of some plants tends to change appreciably over the course of their growing season.
3. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.
4. 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.
5. 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d和e的关系就像是这套题里15题a和c 的关系一样，不能说e完全不对，我觉得是d更直接，而e则次于d，所以还是选最直接的d
