1
P new policy gave cars that normally do not drive out between 1:00am to 5:00 a special decal and a privilege not to check the driver's licenses.
C The theft rate in the special decal cars are lower than the normal cars in the neiborhood.

2
P American children watch tv for more than 5 hour a day; In south korea, the figure is only 7 percent. 15% students in US know the advanced math; but in Korea the figure is 40%.
C if children in America want to do well in math, they must waich less television.

3

C But the scientists said the increased carbon level due to the burning of the fossil fuel would threaten human lives, the scientists should relax and do not worry.

4
P The number of house being sold was decreased. People want to see how the morgage rate would lower.

1.1~5点早上车不开的车按一个d。
结论： 这个要求使得THEFT↓
评估：排除他因，或者是巩固这个关系。
猜想：期间是否有其他治安措施出台？ bingo！
      D不能随时去掉什么的，就是大家都严格按照这个来。
2。 美国孩子看电视多，不懂高等数学
    韩国孩子看电视少，懂高等数学
结论：美国孩子要少看电视，才能提高数学能力。
assumoption: 排除他因： 即没有其它的事情导致韩国孩子数学好。bingo！
             因果未倒置：并非数学好，导致不爱看电视。

3.自然过程调节CO2的含量：CO2多了，雨多，CO2沉淀海床，CO2少，雨少。。
所以人们不用担心CO2多了会危害人类(raise到一个危险的数值）。因为自然可以调节。
削弱： 只要找到其实自然调节不了就好了。找到人工增加和自然状态的不同点。
      如：自然调节需要很长的时间，但CO2危害很快的。bingo！

4.房屋售出降低了，因为消费者在等看抵押利率降到什么最低。同时，房价上涨了。
解释：房价为什么上涨
猜想：所有联系到导致房价上涨的因素都可以。
如： 人们的代价小了，所以房价贵了。bingo!

5.AA：
1）限制和加强都不需要，因为已经有了准则。
2）这个准则适应现在的商业环境因为它过去有效。
3）那句话是神马意思。。。。
好吧。。。ORZ。。。跪求高人指点！

呜呜要哭了敲了半天的字不小心打开别的网页一下子全部木有了T…T

为了交作业那我还是再写一遍吧。。。之前是敲的英语那我现在写中文好了，这次普遍用时较短。30s左右。

1. BG：一个街区推行新政策，夜间1点到5点通常不使用车的车主可以在车上贴上个东东，授权给警察若在这个时段看到汽车出行可以查其驾照。
BG2： 这个街区的汽车盗窃案比其他街区少。
Conclusion: 贴这个东东能有效减少汽车盗窃案~

Evalutate: 是否还采取了其他措施对付汽车盗窃案。

2. 看电视越多，小孩儿数学越差。（我就纳闷了我小时候没多看电视啊肿么回事）
Premise 1: 美国小孩儿看五个小时以上的比例比韩国小孩儿多。
Premise 2：掌握代数几何方面概念的韩国小孩比美国小孩多。
Conclusion: 如果美国小孩想要提高数学就得少看电视！

Assumption: 美国和韩国的基础数学教育在代数几何方面原本就木有差异。

3.  Argument: 大自然会一直调节大气含碳量。
Condition1 若含碳量增加，则大气含热量增加，海洋蒸发增加，雨水把碳又冲刷回海洋里，变成海床的一部分。
Condition 2若含碳量减少，则蒸发减少。
环境学家担心矿物燃料燃烧会过度增加大气含碳量，威胁人类。
Argument: No worries啦，反正大自然会调节的。

Weaken: 当含碳量增加到一定程度时，大自然的调节就会失灵的。

4. BG: 一月新房子的销售量下降。
Reason: 因为抵押利率降低，人们还在观望，看会降低到什么程度。
BG2：销售量下降伴随新房平均房价急剧增长。
Explanation:
先发了 免得又没了==+

Yvette19

接上：
为啥房价会上涨捏？
供求关系好像解释不通，那我猜。。猜不出来看答案吧。。。==+
答案的意思是？高价的那部分房子销售量木有收到利率的影响，因为那些潜在购买者都是有钱淫，他们本来就无所谓利率多高滴。

5. 好吧我被第五题虐了直接看答案咯

1. 58’s

P: if the car has a decal, police can stop it between 1am to 5 am.

P: theft rate is lower for these cars than other cars

C: theft rate in total has been reduced by the program

【因果】有了D，D车偷盗率少了。所以整体偷盗率降低。

整体是否降低，和D在整体中所占比例有关系。如果D比例很大，整体降低合情合理。如果比例小，那么有他因。

评价，削弱方向，看他因。

2. 46’
P: if more television, then less mathematical competence.
P: more than one third of American watch more than 5 hours tv, while only7 percent of the Korean watch.
P: less than 15 percent of American understand geo, while 40 percent of Korean.
C: to improve US math competence, must watch less tv.
【因果】1/3美国人看电视，韩国7%，结果15%美国人熟悉几何，韩国40%。在看电视和数学能力建立因果关系。
有几个gap: 1) 分数不等于number, 美国人看电视的人数不一定多余韩国的。这里假设美国人数更多。2）advanced measurement, geo concepts=mathematical knowledge. 桥梁。3）排他，数学能力只和看电视有关，和其他无关。

3. 1’09
P：natural could adjust carbon level by the circle: carbon—heat—water evaporated—rain—human life
P: increased level of carbon will damage human life
C: not worried, the nature will adjust itself
【逻辑链】环境学家以为增加的carbon会损害人类。但是结论认为，自然自己会调解carbon level，所以不用担心。
削弱：方向就是自然不能调解。如果carbon level超出了自然调解的范围，就不能调解了。或者指出自然可以调解的前提。

4. 27’

P: sales of house drop---interest rate for mortgage reduced—average price of house increased

【差异】销量下降，贷款利率下降，价钱上升。

5.

P: we have a code of ethics

P: the code is relevant to current business environment that was approved last year, and in direct response to violations of companies we were working

C: we do not need ethics regulations and enforcement mechanisms to ensure ethical behavior

1.     错误假设：wrongly assume that the relevant code of ethics we currently have is sufficient to ensure ethical behavior

2.     错误假设：assume that the code that was approved last year is still relevant to current business environment, assume that the business environment did not change within the year

3.     例子代表性：assume the violations by companies we were working are representative of all the possible violations of current companies we are working. Assume that there are no additional or new violations under the current business environment

1. 狒狒logic 倒数第一题
In a new police program, automobile owners in some neighborhoods whose cars are not normally driven between 1 A.M. and 5 A.M. can display a special decal in the cars’ windows and authorize police to stop the cars during those hours to check the drivers’ licenses. The theft rate for cars bearing such decals is much lower than had been usual for cars in those neighborhoods.
If it is concluded from the statements above that automobile theft has been reduced by the program, which one of the following would be most important to answer in evaluating that conclusion?

A: Are
67’
p：不在早上1点到5点用automobile的人车上会有一个标记，那么如果在那个时间段出来了警察会查驾驶证
C：有了这项规定以后thief少了很多
Key：是由于这项规定减少的（而不是还有别的原因）or是在1~5am发现的thief减少special measures to protect their cars against theft?

2. 狒狒logic 倒数第二题
The more television children watch, the less competent they are in mathematical knowledge. More than a third of children in the United States watch television for more than five hours a day; in South Korea the figure is only 7 percent. But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concepts, 40 percent of South Korean children are competent in these areas. Therefore, if United States children are to do well in mathematics, they must watch less television.
Which one of the following is an assumption upon in advanced measurement and geometric concepts than are South Korean children?

39’
P：看电视越多数学越差
P：33%的美国孩子每天看电视超过5个小时，在韩国7%
P：15%的美国孩子掌握一定的math技巧，40%的韩国孩子也有同样的技巧
C：如果美国孩子超过韩国孩子，那么一定看电视看的少
Key：排除会使数学技能差的他因eometric concepts available to children in the United States is not substantially worse than that available to South Korean children.
3. 狒狒logic 倒数第三题
Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmosphere carbon causes decreased evaporation from the oceans, which cause less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax---nature will continually adjust the carbon level.
Which one of the following, if true, would most weaken the argument in the passage?
61’
P：自然会不断的调整大气中C的含量
P：C+→大气更能保温→更多水蒸发→更多雨→更多C从空气到海→形成seabed（反之亦然）
P：有人担心燃烧fossil fuel会使得C+到达一个危险的高度→危害生命
C：不用担心，因为自然会不断调整C的含量 short term
说实话，我现在觉得这个答案不是很好。不过在原题里，这个答案应该算是最相关的。它的着眼点是"over past millions of years"，以此说明“那个时候没有人存在”，从而说明人类这么干会有影响。但是，我能想到的方法还是去说明"Nature cannot withstand such fluctuation."
4. 逻辑大全6-19
In January there was a large drop in the number of new houses sold, because interest rates for mortgages were falling and many consumers were waiting to see how low the rates would go. This large sales drop was accompanied by a sharp rise in the average price of new houses sold.
Which of the following, if true, best explains the sharp rise in the average price of new houses?
A:
P：按揭的贷款I→房子sold的数量-（因为人们想看看贷款利率可以降到什么程度）
P：但是新房每套房子的卖价+，why？le
