为了 不生病,我们要经常锻炼。
aim:不生病
plan:经常锻炼
嗯~谢谢指点哈~~
想了一下,可不可以这样理解:如果说方案被“评估”了,那一定是存在论证过程的,没有论证过程也就不存在推理,也就没必要评估;
而单纯的方案推理,结论就是方案,后面补充的内容可能仅仅是原理(怎么做),或者单纯说会达到目标(这样做了will....),而没有给出论证过程如何达到目标。
下面是几道OG的题,之前不确定,刚刚重新想了下,方便的话能帮我看下这样判断的是否正确吗?麻烦了~~
46. If the county continues to collect residential trash at current levels, landfills will soon be overflowing and parkland will need to be used in order to create more space. Charging each household a fee for each pound of trash it puts out for collection will induce residents to reduce the amount of trash they create; this charge will therefore protect the remaining county parkland.
Which of the following is an assumption made in drawing the conclusion above?
(A) Residents will reduce the amount of trash they put out for collection by reducing the number of products they buy.
(B) The collection fee will not significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out.
(C) The collection fee will not induce residents to dump their trash in the parklands illegally.
(D) The beauty of county parkland is an important issue for most of the county’s residents.
(E) Landfills outside the county’s borders could be used as dumping sites for the county’s trash.
因为论证了:收费-->reduce trash they create-->protect parkland
所以这个是因果
69. Which of the following most logically completes the argument?
By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk. However, a very aggressive species of black ant, the Loma ant, which has recently invaded a certain region, has a venomous sting that is often fatal to humans. Therefore, the planned introduction into that region of ant flies, which prey on Loma ants, would benefit public health, since____.
(A) ant flies do not attack black ants other than Loma ants
(B) Loma ants are less effective than many bird species in competing with rodents for seeds
(C) certain other species of black ants are more effective than Loma ants in competing with rodents for seeds
(D) the sting of Loma ants can also be fatal to rodents
(E) some pesticides that could be used to control Loma ants are harmful to the environment
这个没有论证,只说了会benefit,所以是方案
88. Businesses are suffering because of a lack of money available for development loans. To help businesses, the government plans to modify the income-tax structure in order to induce individual taxpayers to put a larger portion of their incomes into retirement savings accounts, because as more money is deposited in such accounts, more money becomes available to borrowers.
Which of the following, if true, raises the most serious doubt regarding the effectiveness of the government’s plan to increase the amount of money available for development loans for businesses?
(A) When levels of personal retirement savings increase, consumer borrowing always increases correspondingly.
(B) The increased tax revenue the government would receive as a result of business expansion would not offset the loss in revenue from personal income taxes during the first year of the plan.
(C) Even with tax incentives, some people will choose not to increase their levels of retirement savings.
(D) Bankers generally will not continue to lend money to businesses whose prospective earnings are insufficient to meet their loan repayment schedules.
(E) The modified tax structure would give all taxpayers, regardless of their incomes, the same tax savings for a given increase in their retirement savings.
这个有论证过程:实施方案-->more money in these accounts-->more money to borrowers应该是因果;所以是因果
111. Springfield Fire Commissioner: The vast majority of false fire alarms are prank calls made anonymously from fire alarm boxes on street corners. Since virtually everyone has access to a private telephone, these alarm boxes have outlived their usefulness. Therefore, we propose to remove the boxes. Removing the boxes will reduce the number of prank calls without hampering people’s ability to report a fire.
Which of the following, if true, most strongly supports the claim that the proposal, if carried out, will have the announced effect?
(A) The fire department traces all alarm calls made from private telephones and records where they came from.
(B) Maintaining the fire alarm boxes costs Springfield approximately $5 million annually.
(C) A telephone call can provide the fire department with more information about the nature and size of a fire than can an alarm placed from an alarm box.
(D) Responding to false alarms significantly reduces the fire department’s capacity for responding to fires.
(E) On any given day, a significant percentage of the public telephones in Springfield are out of service.
这个没有论证过程,只说了会达到目标,所以是方案 |
