途中用了不少次金山词霸,对于一些词的用法把握不是很准确。大家不用留情地批..
Argument17
The following appeared in a letter to the editor of the Walnut Grove town newspaper.
"Walnut Grove's town council has advocated switching from EZ Disposal (which has had the contract for trash collection services in Walnut Grove for the past ten years) to ABC Waste, because EZ recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC's fee is still $2,000. But the town council is mistaken; we should continue using EZ. EZ collects trash twice a week, while ABC collects only once. Moreover, EZ-which, like ABC, currently has a fleet of 20 trucks-has ordered additional trucks. Finally, EZ provides exceptional service: 80 percent of
respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance."
Outline:
1. E计划添加垃圾车,可能A也计划添加垃圾车,数目可能比E还多
2. 对用户的调查只统计了答复者,没有计入参加调查的总人数以及回复的人中在所有人中占的比例
3. 即使所有用户中的80%对E的服务满意,但也不能排除有更高比例的人对A的服务满意
Citing the fact that the EZ Disposal collects trash twice, is going to order additional trucks and provides exceptional service, the author argues the Walnut Groves’s town council should continue using the EZ’s trash collection services instead ABC Waste despite the more expensive fee. However the author’s argument is lack of contrast and therefore is unconvincing as it stands.
Firstly, the argument assumes that after EZ Disposal’s adding trucks, the total number of EZ’s truck will more than that of ABC. Whereas there is no evidence that shows the ABC company will not add its trucks considering EZ’s addition. Without this consideration, the author’s conclusion is deficient in logic. Perhaps, in order to be more competitive, ABC will increase its truck number after EZ’s enhancement. Thus it’s hard to say which company will have the bigger number of trucks.
Secondly, as mentioned, 80% of respondents are satisfied with EZ’s service, nevertheless we do not know how many people are involved in this survey and what the percentage of the respondents in all informants is. If there are only approximately 100 people participating in the investigation and only a small part respond to the investigation, the survey has no persuasion. To make this survey more persuasive, the author must illustrate the participant number is big and most people offer feedbacks.
Thirdly, the author does not mention what is the percentage of people who are satisfied with ABC’s service while suggests 80% of respondents approve EZ’s service is satisfying. We recede that the 80% is convincing, however, we can not conclude that people are more approving with the EZ’s serving. Maybe there are more people well-pleasing with the EZ’s service, so we can not conclude from the insufficient fact that EZ gives better service. In order to make its demonstration much stronger, the argument should prove the less people are approving of ABC’s service than of EZ’s.
In sum, the argument makes the conclusion from the unilateral analysis, thus lacks persuasion. In order to make this argument more persuasive, the author should add what ABC will do after EZ’s addition of trucks, as well, mention the population involved in the survey and percentage of participants responding to the survey, and demonstrate there are not so many people approving of ABC’s service than EZ’s.
