No.1

Something must be done to ease traffic congestion. In traditional small towns, people used to work and shop in the same town in which they lived; but now that stores and workplaces are located far away from residential areas, people cannot avoid traveling long distances each day. Traffic congestion is so heavy on all roads that, even on major highways where the maximum speed limit is 55 miles per hour, the actual speed averages only 35 miles per hour.
Q:Which one of the following proposals is most supported by the statements above?
AE) New businesses should be encouraged to locate closer to where their workers would live.

SourceSAT TEST 4 SECTION I no.1

No.2

College professor: College students do not write nearly as well as they used to. Almost all of the paper that my students have done for me this year have been poorly written and ungrammatical.
Q:Which one of the following is the most serious weakness in the argument made by the professor?
AA) It requires confirmation that the change in the professor’s students is representative of a change among college students in general.

SourceSAT TEST 4 SECTION I no.2

No.3

Mayor of Plainsville: In order to help the economy of Plainsville, I am using some of our tax revenues to help bring a major highway through the town and thereby attract new business to Plainsville.
Citizens’ group: You must have interests other than our economy in mind. If you were really interested in helping our economy, you would instead allocate the revenues to building a new business park, since it would bring in twice the business that your highway would.
Q1:The argument by the citizens’ group relies on which one of the following assumptions?
Q2:Which one of the following principles, if accepted, would most help the citizens’ group to justify drawing its conclusion that the mayor has in mind interests other than Plainsville’s economy?
A1B) The mayor accepts that a new business park would bring in more new business than would the new highway.
A2A) Anyone really pursuing a cause will choose the means that that person believes will advance the cause the farthest.

No.4

Recently, highly skilled workers in Eastern Europe have left jobs in record numbers to emigrate to the West. It is therefore likely that skilled workers who remain in Eastern Europe are in high demand in their home countries.
Q:Which one of the following, if true, most seriously weakens the argument?
AB) Major changes in Eastern European economic structures have led to the elimination of many positions previously held by the highly skilled emigrants.
SourceSAT TEST 4 SECTION I no.5

No.5  

“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.”
Discuss how well reasoned... etc.

C：quality of care at university hospitals is lower than the quality of other kinds of hospitals
P1: hospitals in our region employ 15% fewer, 20% lower success rate, less profit, payment to staff less
P2: university hospitals divide time
1.        错误假设：错误地假设divide time 和 quality of care 有因果关系。反驳：quality of care 决定于医术，设备，态度等等…divide time 时间少，和quality没有关系，less time 不一定quality low.
2.        范围问题，无效归纳：our region cannot represent the whole nation and generate the conclusion. 反驳：our region fewer doctors, lower success, less profit, less payment 不代表别的地方的university hospital 一样，也不能得出quality of care at university hospital in general is lower.
3.        错误假设：错误滴假设 fewer doctors, lower success, less profit, less payment 和 quality 有因果关系。反驳：fewer doctor不一定quality 低，可能更加能够customized, quality和doctor数量无关。Lower success 也不代表quality, 可以quality很高，但是因为别的原因比如很难治愈，二success low. Less profit and payment和quality 无关，可能part of the profit is devoted into improving of the quality。反正反驳的时候说这些因素和quality都没有关系，这些因素也可以有high quality

1. 【归纳】原来，人们在附近工作和购物，现在商店和上班地方都比较远，必须要走很长距离。同时交通拥挤很严重。
现在要走很远上班，交通又拥挤。如果新的商店等在附近，一切都解决了。

2. 【因果，无效归纳】因为all of the paper of the students of the professor写的不好，语法不对，就说明college students 写的不好吗？典型的一个小范围归纳到大范围college students的无效归纳。样本没有代表性。
It requires confirmation that the change in the professor’s students is representative of a change among college students in general.
问题问的是flaw, weakness而不是削弱。Flaw就是没有代表性。

3. 37’ 市长：要增强经济，要修路。
市民：反对市长想要增强经济，如果真的要增强经济的话，应该要建商业区，因为可以带来修路两倍的商机。假设。
市民的假设应该是，市民认为建商业区可以增强经济，而修路不会。
【二人对话】The mayor accepts that a new business park would bring in more new business than would the new highway.

4. P：东欧技工去了西欧
C：留下来的东欧技工，在本国需求高。
削弱，削弱就是要说需求低。
Major changes in Eastern European economic structures have led to the elimination of many positions previously held by the highly skilled emigrants.
经济结构调整减少了技工的职位。职位减少，当然说明需求低。

Support: No traffic, actual speed can reach limits

2. 10’
Premise: All the papers have done this year are poorly written and ungrammatical
Conclusion: college students do not write as well as they used to be
Weaken: Paper不具有代表性

3. 28‘

4. 23s
Premise: high skilled people have immigrated to the west from east Europe
Conclusion: the left people are in highly demand in their own country
Weaken: 剩下来的人还是超过需求了

5.25’
Premise: 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
many doctors at university hospitals typically divide their time among teaching, conducting research, and treating patients
Conclusion: quality of care at university hospitals is lower than that at other kinds of hospitals
Weaken:  Doctors divide time to do research, teaching because they are better than other doctors
         Fewer doctors because their doctors are too good, do not need that many
         Lower success rate because patients go there have more serious illnesses
         Profit is the not their focus
         Staff want to learn more there instead of earning more money

4. 26s
Premise: Recently a large number of high skilled workers in East Europe emigrate to the West.
