107. Last year all refuse collected byShelbyville city services was incinerated(焚烧). This incineration generated a large quantity of residual ash. Inorder to reduce the amount of residual ash Shelbyville generates this year tohalf of last year’s total, the city has revamped its collection program. Thisyear city services will separate for recycling enough refuse to reduce thenumber of truckloads of refuse to be incinerated to half of last year’s number. Which of the following is required for therevamped collection program to achieve its aim?
(A) This year, no materials that cityservices could separate for recycling will be incinerated. (B) Separating recyclable materials frommaterials to be incinerated will cost Shelbyville less than half what it costlast year to dispose of the residual ash. (C)Refuse collected by city services willcontain a larger proportion of recyclable materials this year than it did lastyear. (D) The refuse incinerated this year willgenerate no more residual ash per truckload incinerated than did the refuse incineratedlast year. (E) The total quantity of refuse collectedby Shelbyville city services this year will be no greater than that collectedlast year. 此题答案是D。 我怎么觉得A也有加强的作用呢,因为如果recycling出来的也被incinerated了,岂不是这个program就无效了吗? 另外想问一下各位NN,逻辑的加强题有什么方法吗?我觉得自己的加强题做的不好。想法和OG的想法经常不一致
原因:焚烧增加了S.制造出的residual ash。 结论说:为了减少ash量,S实施了新的计划,可以减少卡车装载refuse量的一半,这样可以比去年少一半的refuse。 加强:肯定是和ash有关的,如果refuse焚烧出的ash量持续增加,plan是没有办法成功的。 (A) This year, no materials that cityservices could separate for recycling will be incinerated. A说,没有任何材料可以作为在利用而被焚烧的。这个我觉得和conclusion根本没有关系,整个文章在谈论焚烧后的结果,包括premise也是在讨论焚烧出来的ash有在增加,所以这个选项是在否定premise。而且撇开是否否定premise不谈,这个选项没有对文章的conclusion做任何support。文章在说plan的实施是为了减少ash的量,并没有提到其他的或是所有的materials,所以无关~忘记OG的解释了,自己是这么认为的。 |
