咖啡店在他们的网站上加了一个customer feedback page，用来做调查，并且在他们的宣传单上明确的写明了他们的网址以便客户能找到这个feedback page，但是反馈的客户并不多。即便如此这个咖啡店仍然卖出了300000份咖啡，因此他们认为根本不需要这些feedback以提高他们产品的质量
V2六个月了，the hot cup cafe has a website, containing a customer feedback page,然后customers可以submit comments. the website address is clearly printed on the each receipt, so it is not difficult for customer to access the feedback page. 然后呢，那六个月the hot cup cafe卖了300,000cups of coffees，但是customer feedback page最有179个complaints和87个suggestions(大概数字是这样的既不清楚了)。然后就说almost all the customers are satisfied with our current products and customer service department, so we don't have make any improvement。
HOT CUP CAFE的CEO说他们吧网站和feedback page印在了发票上，但是在300000多顾客中，只有187人complaints76人suggestion，所以说不需要改进服务。
V4个咖啡店在他们的网站上加了一个customer feedback page，用来做调查，并且在他们的宣传单上明确的写明了他们的网址以便客户能找到这个feedback page，在这个咖啡店卖出了300，000份咖啡中调查，发现有500+人正评价，100+给了建议。因此他们认为根本不需要这些feedback以提高他们产品的质量(原文说的是to develop the procedure)
A Cafe builds a website to allow the feedback of its customer in the past six months. The address of the site is clearly sited on the **(忘了，单词大家能认识),The site only receive 178 complaint and 33 advise, but the number of total receipts is 33,000.Conclusion:the Cafe does not need to evaluate and improve the service.
[V2] 一个customer service department manager的report:
从六个月前开始，有一个Cafe在每一个receipt上面都印了一个website address，是一个customer feedback page。所以每一个顾客都不难找到。到现在为止，该公司只收到一百多条complaints和不到一百条suggestions，而从有feedback page到现在该公司一共卖了三万杯coffee drink(总之是很大的一个数)。因此可以assume that顾客对这个公司的产品和服务fully satisfied，不需要改进提升之类。
类似：The following appeared in an Avia Airlines departmental memorandum:
“On average, 9 out of every 1,000 passengers who traveled on Avia Airlines last year filed a complaint about our baggage-handling procedures. This means that although some 1 percent of our passengers were unhappy with those procedures, the overwhelming majority were quite satisfied with them; thus it would appear that a review of the procedures is not important to our goal of maintaining or increasing the number of Avia’s passengers.”(39)
V1一个Blastom公司，以前是mining technology，由于mining technology的市场变小，为保证股价和利润，B公司有新战略：让以前研究mining的科学家研究renewable energy，一些公司已经在新能源领域做得很成功啦，所以B公司转向新能源领域能保证股价和利润
V2好像是“能源产品的价格和股票走低，使得一些公司不能盈利，includeB company.然而有一些renewable energy company非常好。B company决定一个策略：将自己公司的researcher去转向新能源，比如风能，太阳能。这样就可以一直保持盈利
V2 mining techchnology will adopt a new renewable energy....
V3 Due to woldwide derease in demand for mining technology, 某公司profit and stock prices went down. 但是有一些prominent companies in renewable technologies发展的很好。因此该公司应该把research的力量全部投入到renewable technologies去，这样就能stay safe from any future decline.
V4 去年矿产业效益不好，利润下降，一个技术公司为了 扭转局面，放弃研究矿产技术开发转而投资研究新能源开发 比如太阳能 风能还有生物能源，取得了良好的效益。 根据这件事写个评价之类的东西，让你讨论在什么情况下，是weaken这个结论的。
Due to the decline demand of the mining technology, all the related corporations are suffering form decline of profit and sales this year, including Blastcom Corporation. Blastcom Corporation is considering adopting one growth strategy: to shift some of the researchers from mining technology to the renewable energy technology, the demand for the renewable energy such as solar energy. Some of the prominent companies which market the renewable energy are successful in recent years. Therefore, it is guaranteed that company Blastcom will also be successful in the future by providing renewable energy
last year Apex manufacturing bought home computers and paid to telephone connections for its managers so that managers could get access to company file data and did additional work after normal business hours. And the productivity of APEX increased by 15%. 所以作者建议other companies也应该为员工在家里提供access to company resource，这样可以提高productivity以及increase profit.
原题：The following appeared as part of an article in a computer magazine.
”A year ago Apex Manufacturing bought its managers computers for their homes and paid for telephone connections so that the managers could access Apex computers and data files from home after normal business hours. Since last year, productivity at Apex has increased by 15 percent. Other companies can learn from the success at Apex: given home computers and access to company resources, employees will work additional hours at home and thereby increase company profits.”
Notice that only managers were bought computers by Apex, whose productivity indeed rose 15 percent as the result. It is different from the assumption made in the article, which stated that if all employees were brought computers, they would work extra hours at home. Managers ≠ all employees
A. This argument suffers from a fallacy of post hoc, ergo propter hoc.
B. Next, the author fails to provide any evidence that installing home computers for managers really led to the increase of Apex’s productivity.
1 home access 和increase productivity因果关系错误
4 hasty generalization。有两个，一是把apex推广到所有公司，二是把managers推广到了所有employees
In this article the author attributes Apex Manufacturing’s 15 percent increase in productivity over the past year to its decision to equip its manager with computers and paid telephone connections for their homes so that they would access company computers and files from home after normal business hours. On the basis of Apex’s experience the author recommends that other companies follow Apex’s example and provide computers and access to company resources to their employees. The author believes that such a policy would increase productivity and profits for other companies, just as it did for Apex. The author’s line of reasoning is questionable for several reasons.
First, the author assumes that Apex’s increase in productivity is due to its equipping its managers with home computers and access to company resources. However, the only evidence offered in support of this claim is the fact that Apex’s increase in productivity occurred after the home computers and after-hours access was provided. Unfortunately, this evidence is insufficient to establish the causal claim in question. While temporal precedence is one of the conditions required to establish a causal relationship between two events, by itself it is not a sufficient condition. Consequently, it is possible that Apex’s increase in productivity is not related to its decision to equip its managers with computers and after-hours access in the fashion required by the author’s argument.
Second, the author assumes that Apex and other companies are sufficiently similar to warrant a conclusion based on an analogy between them. Even if we accept the view that Apex’s increase in productivity was brought about by its policy of enabling its managers to work from home, differences between Apex and other companies could nullify this result. Lacking detailed information about Apex and the other companies in question it is difficult to assess the author’s conclusion.
In conclusion, the author’s argument is unconvincing. To strengthen the argument the author would have to provide additional evidence for the claim that Apex’s decision to provide its managers with home computers and access to company resources was responsible for its increase in productivity. Furthermore, it would be necessary to show that Apex and other companies are sufficiently similar to justify the analogy between them.
原题：The following appeared as part of a recommendation from the business manager of a department store.
“Local clothing stores reported that their profits decreased, on average, for the three-month period between August 1 and October 31. Stores that sell products for the home reported that, on average, their profits increased during this same period. Clearly, consumers are choosing to buy products for their homes instead of clothing. To take advantage of this trend, we should reduce the size of our clothing departments and enlarge our home furnishings and household products departments.”(70或71，版本不同)
1、A period of three month is too short to draw a general conclusion of the overall trend.
2、The past three months' trend does not guarantee the same in the future.
3、Whether the reports from the local clothing stores and stores that sell products for the home are reliable or not are still open to doubt, thus making the author's suggestion groundless.
