Argument:
43. The following appeared in an article in the health section of a newspaper.
“There is a common misconception that university hospitals are better than community or private hospitals. This notion is unfounded, however: the university hospitals in our region employ 15 percent fewer doctors, have a 20 percent lower success rate in treating patients, make far less overall profit, and pay their medical staff considerably less than do private hospitals. Furthermore, many doctors at university hospitals typically divide their time among teaching, conducting research, and treating patients. From this it seems clear that the quality of care at university hospitals is lower than that at other kinds of hospitals.”
报纸的健康板块上的文章：
有一种普遍的错误观念认为大学医院比社区或私人医院更好。这个想法是无根据的，我们地区的大学医院较之私人医院，少雇15%的医生，对患者的治愈率要低20%，总体利润要小得多，给一户员工的待遇比私人医院低很多。而且，很多大学医院的医生将他们的时间分为教学，指导研究和看病几部分。从此可明显看出大学医院的服务质量比其他医院低。
1， 从一个医院的情况就推广到整个太草率
2， 治愈率低可能是因为接受的患者得的病都比较罕见等原因造成的
3， 工资低，总体利润低，时间分配给教学都不能一定说明质量差。可能其他福利好，接受的病人少，教学研究有助于进步
44. The following is part of a business plan created by the management of the Megamart grocery store.
“Our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop shopping. The surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. We should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.”
Megamart杂货店的管理层的商务计划：
由于我们在杂货店内加了药剂部分，今年我们的总体销售额增加了20%。显然，顾客主要关注的是一次性购物的便利性。在今后两年内提高我们的利润的最佳方法是增加一个成衣部门和一个汽车配件和维修商店。我们同时也应该在最后的几年中继续增加新的部门和服务，比如餐馆，园艺商店。成为本地唯一的提供如此广泛服务的商店将给我们带来超越其他商店的竞争优势。
1. 总体销售额增加20%利润不一定也会相应增加
2. 销售额的增加不一定是由于增加了这个部门造成的
3. 以后是否还会有如此效果不一定。因为可能已经有企业提供更专业更优质的商品和服务。
1. 没有建立因果。sequence不能证明因果。不知道收入来自哪个section. 很可能是有其他的原因：很可能是pharmacy没有利润。利润来自其他的部分。比如食品等，质量提高，或者经济情况好，人们有更多的demand。
2. 销售额增加不一定是profit增加。
3. 错误类比：就算加入了pharmacy引起了收入提高，也不能说增加的clothing和其他也会引起收入。很可能人们不是因为convenience，而是对medicine的需要。很可能其他的，人们更愿意到special shops。英语作文
