花了n多时间把所有讨论全部看完。虽然写回帖还要花时间,不过算是给后来的人一个更清晰的思路吧。 这道题有三个难点。 第一个是明白题目类型: 虽然问的是rests on a questionable presupposition,但是应该明白就是assumption的题型;这个和questionable没有太大关系,不要搞成weaken题型了。 第二个是阅读理解的问题: 这里其实有很多同义表达 "fast cycle"=="eliminate bottlenecks and delays"=="speed up production" "ensures quality"=="is done right the first time" 所以原文的推理结构可以简化成这样: 因为(前提)产量不能加快除非质量没有问题(就是说:加快了产量就一定能保证质量)。(The reason is that the bottlenecks and delays cannot be eliminated unless all work is done right the first time.) 所有(结论)这个加快产量的策略不仅能加快产量,而且还能保证质量。(Not only does it speed up production, but it also ensures quality.) 第三个问题是not A unless B,充分必要的推理问题: not A unless B ==> A --> B,前提的逆否命题就是,not B --> not A,就是答案A “有质量问题就不能加快产量” (A. any flaw in work on a product would cause a bottleneck or delay and so would be prevented from occurring on a "fast cycle" production line) 其实这题在真是考试的时候碰到,不一定一下想地这么清楚的。 但是用有关无关很好排除其它4个答案的。
无关项用红色注明: (B) the strategy of "fast cycle time" would require fundamental rethinking of product design (C) the primary goal of the organization is to produce a product of unexcelled quality, rather than to generate profits for stockholders (D) "fast cycle time" could be achieved by shaving time off each of the component processes in a production cycle (E) "fast cycle time" is a concept in business strategy that has not yet been put into practice in a factory
