标题: 请教大全-12-14,大全-12-19
14. The most important aspect of moviemaking is
conveying a scene's rhythm. Conveying rhythm
depends less on the artistic quality of the individual
photographic images than on how the shots go together
and the order in which they highlight different aspects of the action taking place in front of the camera.

If the statements above are true, which of the
following must be true on the basis of them?
(A) The artistic quality of the individual photo-
graphic image is unimportant in movie
photography.
(B) Photographers known for the superb artistic
quality of their photographs are seldom effec-
tive as moviemakers.
(C) Having the ability to produce photographs of
superb artistic quality does not in itself guar-
antee having the ability to be a good
moviemaker.
(D) Movie photographers who are good at their
jobs rarely give serious thought to the artistic
quality of the photographs they take.
(E) To convey a scene's rhythm effectively, a
moviemaker must highlight many different
aspects of the action taking place.

答案：C，C是原命题的逆否命题，可是E也对，是不是E提出了一个effetively，这个题干琐有的概念呢？

19. Most geologists believe oil results from chemical
transformations of hydrocarbons derived from
organisms buried under ancient seas. Suppose,
instead, that oil actually results from bacterial action
on other complex hydrocarbons that are trapped
within the Earth. As is well known, the volume of
these hydrocarbons exceeds that of buried organ-
isms. Therefore, our oil reserves would be greater
than most geologists believe.

Which of the following, if true, gives the strongest
support to the argument above about our oil
reserves?
(A) Most geologists think optimistically about the
Earth's reserves of oil.
(B) Most geologists have performed accurate chem-
ical analyses on previously discovered oil
reserves.
(C) Ancient seas are buried within the Earth at
many places where fossils are abundant.
(D) The only bacteria yet found in oil reserves could
have leaked down drill holes from surface
contaminants.
(E) Chemical transformations reduce the volume of
buried hydrocarbons derived from organisms
by roughly the same proportion as bacterial
action reduces the volume of other complex
hydrocarbons.
答案：E，我用排除法做的，请问E是如何加强的呢？

谢谢。

1. 有点tricky. 我在读完C时知道是正确答案, 读了E有想了想, 发现E是错的. E迷惑性在于它还有原文的关键词和短句"highlight many different aspects of the action taking place". 但是ETS用了偷换概念的方法来迷惑我们. 原文说depends less on ... than ... and the ORDER IN WHICH they highlight different aspects of the action taking place." 既highlight different aspects的order是重要的, 而不是highlight本身是重要的.

2. 很多逻辑题实际是数学题, 可能是概念性, 可能是计算. 概念性的题目通常是rate和总量, 计算通常是proportion. 读完此题, 你要意识到它是两个量在比较, 和数量, 或和量有关. 所以答案很可能是含有数量或量概念的选项. 原文说chemical transformation产生石油. 但如果是bacteria作用, 现在的石油量会更多, 原因是bacteria作用的原料量大于chamical transformation (CT)的量. E的意思是CT和B生成石油的过程中原料的消耗比例相同. 加强. 因为如果两个量, 如果A>B, 两边同时减少同一比例, 不等号方向不变 (1-r%)A>(1-r%)B.

另外, E不是assumption. 因为取非原结论也可能正确. 这就是含有数学概念的逻辑题目与其它题目不同之处. 即使B消耗量大于CT消耗量, 剩余量还可能是(1-r%)A>(1-0.5r%)B. 取决于A,B的值.

mindfree,thank u very much! U give me a clear picture on how to solve these problmes.

BTW, i ususlly didnot detect such tricks of ETS as substitution of words and phrases.

Thanks.

我14题也错选了E，看了mindfree的解释，觉得真好！

以下是引用mindfree在2003-4-26 10:40:00的发言：

请问黄色highlight部分是什么意思？题目中表示出这层含义了么？这不是与E矛盾么？？

请问题目中As is well known, the volume of these hydrocarbons exceeds that of buried organisms. 这句话是什么意思？H和细菌，植物之间是谁作用谁啊？

总算看明白题目在说什么了，好不容易。。。
