在网站上做了逻辑题,对这一题很有感触。总结了一些方法,希望能对和我一样的小伙伴有用。如果有不同意见欢迎指出。
题目:
Snowmaking machines work by spraying a mist that freezes immediately on contact with cold air. Because the sudden freezing kills bacteria, QuickFreeze is planning to market a wastewater purification system that works on the same principle. The process works only when temperatures are cold, however, so municipalities using it will still need to maintain a conventional system.
Which of the following, if true, provides the strongest grounds for a prediction that municipalities will buy QuickFreeze's purification system despite the need to maintain a conventional purification system as well?
- ABacteria are not the only impurities that must be removed from wastewater.
- BMany municipalities have old wastewater purification systems that need to be replaced.
- CConventional wastewater purification systems have not been fully successful in killing bacteria at cold temperatures.
- DDuring times of warm weather, when it is not in use, QuickFreeze's purification system requires relatively little maintenance.
- EPlaces where the winters are cold rarely have a problem of water shortage.
我选了D,但是后来想了很久才想明白为什么选C。问:那个提供了最有力的支撑说市政当局尽管在维持/供养旧的系统的同时,还要购买新的系统?注意这里despite是尽管的意思,我觉得和although一样,引导的东西都不是这句话要表达的重点,而另一句才是。所以这句话的意思是说:为什么(保留了旧的还要)买新的?适当的逻辑应该是新的有比旧的好的地方(所以买新),但是也有比旧的不好的地方(需要旧的来弥补)。所以题目中所有说新旧对比的应该都可以。而我原来的理解是:为什么买了新的还要维持旧的?细细体会这两者的不同。关于maintain的理解也影响了这句话的重心,我以为maintain得是花大力气大价钱那种维持,但是:1. To continue to have, to keep in existence, or not allow tobecome less; 2. To keep a road, machine, building etc.in good condition.3 toexpress firmly your belief that sth is true. 4. To provide someone with food andwhatever is necessary for them to live on. 读下来并没有很费力气的感觉,就是正常的“保持,和原来一样”的感觉。
A:无关;B:如果replace了那就不需要保持旧的了;C:说明新比旧好,所以要买新的。D:其实我选D就是默认了C的选项,即新的比旧的杀菌好,但是新的只能在低温使用,所以新的在夏天的时候就会lack of use,产生新的成本,这个时候就要用旧的。而新的在夏天的时候成本低,对于市政当局来说就是好事-维持旧的同时也会买新的。总结下来会发现D的逻辑推断太长了,而且人家只是说了为什么要在保留旧的的情况下买新的,新的在夏天成本低只是新的自己的好处,并不能体现出新旧的对比。E:无关。
以上。
