以下是引用jaredyu在2005-12-3 18:31:00的发言:看了很久总算是明白了。 选项取非:lawmakers DO allow for revenue lost =>题目结论不成立:vicious cycle not results。 即选项是题目结论的必要条件。也就是 文章结论成立:vicious cycle results =>选项lawmakers do not allow for revenue lost。 这样正符合了 not A unless B = not A if not B = A推出B 以下是引用crusaders在2003-12-24 15:43:00的发言: The vicious cycle described above could not result unless which of the following were true. ===> The vicious cycle described above could not result if which of the following were not true. ===> IF The vicious cycle described could reasult, Which of the following were true. 这回对了:]
这一题我们要从选项中选一个作为假设对吗?? not A,unless B=not A,if not B =if A,then B 如果这个成立的话,这题的问句 原文中是The vicious cycle described above could not result unless which of the following were true?
我改成题目这样问,If the vicious cycle described could result, Which of the following were true? 是不是和原文中的问题是一样的,也就是遇到这个的问题,从选项里面也是找一个假设? 我自已觉得挺有道理的,但是不太确信,请指点。 谢谢。
