以下是引用tania在2005-8-29 15:42:00的发言:明白了,我又犯了以前做逻辑时犯过得错误,原文中指出 Further- more, the daily movements of sloth (20) bears and American black bears— which are similar in size to sloth bears and have similar-sized home ranges— reveal similar travel rates and distances, suggesting that if black bear cubs are (25) able to keep up with their mother, so too should sloth bear cubs. 这在逻辑关系中是一个论据,是一个事实,不可以去否定论据的可靠性,只能否定论据与论点之间的逻辑关系,对吗?不过我没觉得c选项有加强的意思啊
对,这是背景性质的东西,关于这点,tania可以看一下OG的128题,
OG-128. >>
Reviewer: >>
>>
The book Art's Decline argues that European painters today lack skills that were common among European painters of preceding centuries. In this the book must be right, since its analysis of 100 paintings, 50 old and 50 contemporary, demonstrates convincingly that none of the contemporary paintings are executed as skillfully as the older paintings.>>

Which of the following points to the most serious logical flaw in the reviewer's argument?
(A) The paintings chosen by the book's author for analysis could be those that most support the book's thesis.
(B) There could be criteria other than the technical skill of the artist by which to evaluate a painting.
(D) The particular methods currently used by European painters could require less artistic skill than do methods used by painters in other parts of the world.(A)
OG对BD选项的解释:
Choices B and D are both incorrect because a sharply defined focus is not a flaw in an argument; the reviewer makes clear that only artistic skill and only European painters are being considered. |
