看看，尝试一下

Kya

因为一站CR是鸡肋。。这次下定决心要把它给啃了。。。第一次做。。。肯定会被鄙视的很厉害~~不过无所谓啦。。要坚持！
Timer开了以后找不到了，木有计时- -…
精炼题：
P :C has Solved only 1 out of 25  than any other detectives in the last 3 years
C: C is an incompetent detective
weaken推测：1.any other detectives have solved only few cases
              2.Maybe this only 1 case is the most complicated one
选择A ，符合推测2
选项解释：B.无关选项；C.迷惑选项，但是不能直接攻击到逻辑链；D.加强；E.无关选项
逻辑链题：
3.
BG：elder people’s fall cost much
P：the new(t?) program can prevent BG happened but cost much
C: the program cant be adopted
weaken推测：key point在cost上，故方向可以是1.不adopted 则cost更多；2.相比其他的program这个方法已经算cost最少的了；3….
选择C,符合推测1
选项解释:A.没有涉及cost，无关选项；B.无关选项；C.medication is not counted说明原来的cost实际是减少的，指向了推测方向1；D.未涉及cost，无关选项；E.迷惑选项，只解释了why new program cost so much的原因，不涉及因果
总结：这道题选项看太久了，实战会跪！

刚开始先两道练练手~~明天上班休息的时候来补作业

逻辑链题
2.BG：Although f were first found in the lab, they were also found in nature
P:the synthesis of f in lab requires distinctive conditions
C:the discovery can evaluate the hypotheses of the state of the Earth’s crust at the time f were formed
Weaken推测：1.f were formed 的条件太苛刻以至于lab达不到；2.lab出来的结果不完全和at the time f were found一致；3.有其他因素可以达成f were formed的条件，但这个因素lab无法达到；4….
选择D，因为合成的是unknown crystalline 结构，故无法从实验来验证假设，割断因果
A无关选项；B.f  were found 在其他地方与因无关；C.迷惑选项：与因无关；E.重复了P
**关于C选项补充：只是重复文章的信息，没有削弱结论
4.BG：voles in large groups form fall to winter and live in small groups from spring to fall
P：A seasonal variation in mortality among young voles
C: The seasonal variation in group size
Strengthen 推测：1.seasonal variation导致秋天食物多？/or生殖能力强？/…小老鼠死亡率低；2.mortality among young voles只和seasonal variation有关或者seasonal variation只导致了小老鼠死亡率的变化
选择E，排除他因，指向推测2
选项分析：A.weaken; B.无关选项；C.weaken；D.无关选项
总结：逻辑链都能写对，可是读题累…基础差伤不起啊Ｔ．Ｔ

1. 计时看问题和题干，一般在45s内。
2. 先不看选项、不看题干按自己的理解写出逻辑链。
3. 合理推测正确选项的可能方向
4. 看选项，选出正确答案
5. 校对答案，对错误选项给出错误原因和类型的解释，对正确选项分析其与题干逻辑链的关系。

1. P:solve smaller percentage case
C:incompetent

Weaken:salve少但不能说明incompetent, 这些case 可能很难

A:Correct
B:与incompetent无关
C：加强，证明他更弱了
D：another city无关
E:与incompetent无关


2.
B:F in lab, 发现 in nature, formed in fissures of shungite
p:lab合成F distinctive condition: temperature and pressure
C:可evaluate earth' curst form state

weaken:F Form 在nature与lab不同，无法参考

D:in nature structure unknown, 直接削弱，所以无法evaluatte自然形成过程

3.
p:new treatment比average 贵
C： new treatment cannot be justified

W:忽略其他原因，new treatment不贵

C:average 一部分cost未算，所以new 不一定贵

4.
P:voles live together for extended family
p2:秋-冬larger group, however, 春--秋，small group
C:季节变化是因为mortality young volves

S:春-秋有什么原因导致voles 需小范围，才能morabilty
Remark:however后是重点

A:generally 春-秋 young voles多，没有接受原因
E:因为predaor only 春-秋active, 所以small group for morability

5.
beach feeding, dolphin (adult) benefit
offspring 也应该 live longer, 但没有
adult, offspring类比，找不同

1. 15”
Premise: He has solved a smaller percentage of the cases assigned to him in the last 3 years—only 1 out of 25—than any other detective on the police force.
Conclusion: Carl is clearly an incompetent detective.
Prehase:  His cases are different from other detective’s
A Right
B C E 无关  D 加强
2. 30’
Background information: Although fullerenes--spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite.  
Premise: Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure
Conclusion: this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed.
Prehase: the formation in the labs is different from that in nature
D
3. 15”
Background information: On average, the emergency treatment for an elderly person for injuries resulting from a fall costs $11,000.  A new therapeutic program can significantly reduce an elderly person's chances of falling.  
Premise: this treatment program will cost $12,50
Conclusion: thus cannot be justified
Prehase: it will save other costs from reducing the chance of falling
A,B--irrelevant
C--right
D,E--support
4. 20”
Background information: The prairie vole, a small North American grassland rodent, breeds year-round, and a group of voles living together consists primarily of an extended family, often including two or more litters.  
Premise: Voles commonly live in large groups from late autumn through winter; from spring through early autumn, however, most voles live in far smaller groups.
Conclusion: the seasonal variation in group size can probably be explained by a seasonal variation in mortality among young voles.
A—what about early summer to autumn?
B--weaken
C—irrelevant
D--irrelevant
E--right
5. 15”
Premise: A popular beach has long had a dolphin feeding program in which fish are given to dolphins several times a day; many dolphins get as much as half of their food each day there.
Conclusion: dolphins that first benefit from the program as adults are healthy and long-lived, their offspring have a lower life expectancy than offspring of dolphins that feed exclusively in the wild.
Prehase: offsprings的情况
A.B,C,D--irrelevant
E--right

小分队获益匪浅，虽然没回贴，但是在本子上详细的写了。然后对照大家的想法确实很有提高。会坚持下去

为什么看不了各题的选项？

宝爱一

一：Premise：Carl solve fewer cases than other detective in the past 3 years.
Conclusion: Carl is incompetent detective.
Prephrase: Carl处理的都是复杂的case，incompetent不光指数量，还要质量。
AnalysisA) Because the police chief regards Carl as the
most capable detective, she assigns him only
the most difficult cases, ones that others have
failed to solve.  证明Carl有能力，削弱结论
(B) Before he became a detective, Carl was a
neighborhood police officer and was highly
respected by the residents of the
neighborhood he patrolled.与之前职业无关
(C) Detectives on the police force on which Carl
serves are provided with extensive resources,
including the use of a large computer
database, to help them solve crimes.帮助他人完成案子，无关或加强他有能力
(D) Carl was previously a detective in a police
department in another city, and in the 4 years
he spent there, he solved only 1 out of 30
crimes.自己和自己比无关
(E) Many of the officers in the police department in
which Carl serves were hired or promoted
within the last 5 years.无关

二：逻辑链：special condition make F form——地球的crust有这样的自然环境
F形成的过程中是否变化，是不是别的星球带来
A：无关
B：一些小的碎片在spacecraft找到，right
C:carbon 无关
D:被安排在未知晶体中，so？无关
E：S在特定环境下可以自己形成，跟地球无关。

三：BG：老人falling治疗费花了11000
premise：新治疗方案花了12500，大于falling的治疗费，所以不采取。
conclusion：减少花费
Prephrase：falling当时治好之后的后续费用更重。
A
B跟自己住无关
Cfalling之后要长期治疗，花的钱没算在紧急治疗费里 right
D新的项目focus不重要
E新项目里的费用的一大部分是怎么怎么无关


四：BG：vole群居，带两三个小的，晚秋到冬，春到早秋通常live大group，但大多数live in small group
逻辑链：小vole随季节变化的死亡率——group size的大小。
季节harsh的时候vole死了很多
A：春和早夏，范围不对。
B：size年年变，so？无关
C：吃的东西只有在spring才多
D：冬天vole的habitat harsh right
E：蛇无关

实在不会用英文完整表述啊。。。我就这么中文夹着英文弄吧。。。嘎嘎嘎
