dorbear, 1) 请问BF4根据你的理论该怎么选呢?谢谢
2) "a conclusion that must be drawn from this argument."和"a conclusion that can be drawn only from the ..." 这种选项基本上就是错的吧?

4. More and more computer programs that provide solutions to mathematical problems in engineering are being produced, and it is thus increasingly unnecessary for practicing engineers to have a thorough understanding of fundamental mathematical principles. Consequently, in training engineers who will work in industry, less emphasis should be placed on mathematical principles, so that space in the engineering curriculum will be available for other important subjects.
The two portions in boldface play which of the following roles?

(A) The first is the second-premise that the argument includes; the second is the conclusion that could be drawn from this passage.
(B) The first is the fact that is necessary for this argument; the second is the conclusion that must be drawn from this passage.
(C) The first is the part of premise that the argument includes; the second is the inference that could be drawn from this passage.
(D) The first is the part of evidence that supports this argument; the second is the inference that could be drawn from this passage.
(E) The first is the first conclusion in this argument; the second is the second conclusion in this argument.

先回答问题：
1、所有的逻辑，基本都是一个模式： 从已知的事情 =〉未知的事情
已知的事情，可以是Principle, Basic Truth, Premise，甚至是另外一个命题，总之无所谓叫什么，也用不着区分。只要知道那些是论据，哪些是结论就可以了。

2、推论题必须绝对严格按照原文的文字内容；不能有任何超过原文的假设和附加条件；推论题的答案可以来源于原文的任何一个地方；或者是对其中一句话的改写、对比、取逆反、类比、归纳，计算等等，甚至可能是原文命题中的一个假设；

3、结论题（conclusion）是推论的一种，是针对文章整体的推论，一般出现在段落开始或结尾部分。既然结论是推论的一种特殊情况，在一道推论题中，结论和推论不可能同时出现在选项；换言之，如果出现任何一个，肯定是答案；

（E）是答案；首先划线的部分没有一个是论据，都是从已知推导出来的东西；然后我看了一下选项，有四个说第一个划线是论据，不管是带着什么帽子，所以我看都没看就选E．虽然第一个划线从技术是一个INFERENCE，我的想法是：只有Conclusion 和 Inference 在一道题的不同选项中同时出现时才去考虑它们的区别，否则，管它呢！对吧。

2) "a conclusion that must be drawn from this argument."和"a conclusion that can be drawn only from the ..." 这种选项基本上就是错的吧?
不可以这样下结论，一定要看原文。设想一下，如果原文存在一个充分性论据，a conclusion that must be drawn from this argument　就可能是对的；如果原文存在一个充分必要性论据，那么a conclusion that can be drawn only from the　也是能成立的。

C
1. 关键看作者写这段话想说明什么?
是"it is thus increasingly unnecessary for practicing engineers to have a thorough understanding of fundamental mathematical principles"?
还是"Consequently, in training engineers who will work in industry, less emphasis should be placed on mathematical principles"?
还是"space in the engineering curriculum will be available for other important subjects."?

I think the CONCLUSION is "Consequently, in training engineers who will work in industry, less emphasis should be placed on mathematical principles"

2. 如果没有第一句话,CONCLUSION将不成立.SO第一句话是PREMISE (mid-conclusion as a premise)

A suggests that no matter how much weight art historians give to a disputed painting (means no matter how cautious they are in assigning the art work to an author), art dealers will always do the opposite, assign the art work to an author to make the best profits. So, it weakens the position taken by the art historians. Their efforts are weaken by the actions of art dealers.

你的理解完全正确，正因为 business低估了环境事故的危险，他们会继续不去采取措施保护环境，结果为了利益，business会去保护环境的结论被削弱了。

b的意思是，当挥发的水被包含在了冰里，更多的oxygen-16 than oxygen-18留在了冰里而不能返回到seawater,the percentage of oxygen-18 will increase. Right? do a little calculation.

A不对。如果有消耗国内的石油，其他什么都没变，A 就不能解释the level of extractable oil reserve is unchanged. E说明the increase of extractable oil reserve have accomodated the consumption of demestic oil reserves, so the result is the level of current extractable oil reserves is as same as the previous level (without considering the available extractable oil reserves due to the new technology)

我用排除法。A肯定不对。因为文中第一句话就说，爬坡的能量和体重成正比，所以大动物肯定需要更多的能量。b是对文中一句话的重复. D只说明了大动物的能量供应比小动物多,没有和the energy needed to move the uphill联系起来。E是无关选项。我们可以直觉的理解C, 大动物surface relatively 小, body weight relatively 大, 能量供应少，但需要爬坡的能量多，所以慢。小动物surface relatively 大, body weight relatively 小，能量供应多，但需要爬坡的能量少，所以爬坡的速度和平时行走的差不多。C是唯一把energy needed to move uphill and energy output联系在一起的选项。两者一起才能决定爬坡的速度。

This is the first time I provide the feedback, please feel free to comment. I am sure there are many places I need to improve. Thanks.

You are doing great fye! Welcome and stay tuned.
