146The following appeared in the editorial section of a local newspaper.
"The librarians in our town's school system have reported that the number of trips that our students make to their school library on a voluntary basis has decreased significantly in recent years. For example, the average seventh-grade student visited the school library five times last year, but four of those visits were part of required classroom activities. This shows that our students are reading less than in the past. To address this problem, our town needs to improve the atmosphere of the libraries so that they will be comfortable places in which to work. If students view the libraries as uncomfortable, then they are unlikely to want to spend much time there."

1.装修也不一定有人来
2.来的少不一定阅读量少了
3.统计可能不准,而且只有7年纪的,不代表全体
这个,题目开始看错了,issue17 看成a了,就写了。有时间大家帮我看看
At first glance, the arguer's reasoning seems to be quite sound. According to his conclusion, we should make improvement to the atmosphere of the libraries to attract much more students going to the libtary in his town . But unfortunately, if we make a careful confederation of his evidence, doubt will be cast on this conclusion .
In the first place , the argument is based on an unwarranted assumption that to make students want to send much time on the town's library, it is useful to improve the condition of library. There is not any evidence in this argument to point out that students voluntarily go to library to enjoy its confortable condition . It is well known that , reading book is ultimate purpose for students make to the library. If someone only want to do enjoyment, may be the cinemas or parks are more suitable compared with grave and pacific library.
In the second place, the argument told our an instance shows that the students are reading less than in the past. Apparently, the arguer commits a fallacy of hast generalization. Though the number of visitors in the library were less than the past two years, is doesn't necessarily mean that Other students are short of quantity of reading books. The arguer are failing to consider other possible alternatives. Such alternatives may include the fact that they prefer learn much more knowledge on the internet which has abundant information and is more convenient than conventional method such as reading books. As a consequence , unless the arguer take these probabilities into account ,we con not accept what he claims.
In the third place, the report concerns about the average seventh-grade student visited the school library is too vague to be informative . Firstly, the arguer is unable to prove that whether this report can be finished by the administrator’s impression or putting down in writing .Secondly, The content of report barely refers seventh-grade student, which is a little part of all students of this town's school. How about others? We can not find their instance in the argument. Even if only considered with seventh-grade students, the arguer's conclusion is still ungrounded. Perhaps , seventh-grade students had much more movement such as summer camp ,Olympic competition and so forth.
In sum, it's unwise to make rash decision on improving the condition of the libraries to attract more students only taking the superficial advantages into account. More detailed survey of reading status of all students in this town last years and other important issues should be taken.
17The 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.
At first glance, the arguer's reasoning seems to be quite sound. According to his conclusion, we should still select EZ because of some seeming right advantages. But unfortunately, if we make a careful confederation of his evidence, doubt will be cast on this conclusion .
First of all, the decision of town council is possibly wrong. According to its reflection, higher fee of EZ is the exclusive cause to switching from EX to ABC. However , we can't find any evidence to support it. Maybe the town coupil are failing to consider other possible alternatives to change the contract for trash collection services. Such alternatives may include the fact that the quality of collect trash of EZ were too bad and the staff 's attitude of service was too abominable to be accepted by the residents of Walnut Grove town. People had have enough of that style of thing , they prefer pay much more expense to barter knight sarvice .
In addition, the arguer refute town council 's decision by his own seeming right precondition that raising monthly fee of EZ is reasonable. And he gave some evidences involved in the article to sustain his assumption. For example, he said that EZ collects trash twice a week, while ABC collects only one. But he can't adequately prove that EZ could dispose more trash than ABC every week. Further, EZ has increased additional truckers to advance its capacity of transportation. Though EZ has made progess, it is still hard to compare with ABC's transportation according to this argument. Perhaps, EZ has about 30 trucks after adding 20 trucks, while ABC has 100 trucks. Anyway, the provided proofs are not enough to explain why EZ raised its fee.
Finally, the results of the survey are neither relevant nor convincing. Lacking information about the number of residents and the number of respondents, it is impossible to access he validity of the results. For instance, if 10 residents were surveyed but only 8 responded, when the population of town is about 10,000, the conclusion that the residents were satisfied with EZ's performance would be highly suspect.
In sum, it's unwise to make rash decision on whether selecting EZ or ABC only taking the superficial advantages into account. More detailed survey of the advantages of EZ and ABC and other important issues should be taken. |
