2) 逻辑链Situation
Premise:
only work 1 case out of 25cases
Conclusion:
A is a terrible detective
3) 推测(Prephrase: mentally formulate your answer to the question stem)：
the one case is a coplicated one,hasn't been solved for many years
4) 选项分析：选A
*选项解释不提供固定思路，请根据自己的理解对每一错误选项给出错误原因和类型的解释(无关选项思考清楚为什么无关)，对正确选项分析其与题干逻辑链的关系。
A it proves the competence of A
   we can expect that harder cases, lower success rate. And the answer supplement new information so the conclusions is not undermined.
B the past experience cannot help to explain
C the advantages of the police station(not relevant to the ability of A)
   The opposite answer strengthened the argument.
D 更加说明A能力不行(another opposite answer)
E other people's achievement have no relation to A's

      二      
1) 计时：85s
2) 逻辑链Situation
cause
A can be synthesized in the labortory
result
scientists in labortory can provide geologists with some information about the  crust(temperature) needed for A forming naturally on the earth
3) 推测(Prephrase: mentally formulate your answer to the question stem)：
A can be synthesized without any 模拟 environment
4) 选项分析：选D
*选项解释不提供固定思路，请根据自己的理解对每一错误选项给出错误原因和类型的解释(无关选项思考清楚为什么无关)，对正确选项分析其与题干逻辑链的关系。
A not relevant to the forming evrionment of fullerenes
B not helpful for getting more information about the forming environment
C same as A&B
D naturally fullerence is unique and cannot be copied by the synthesized fullerence so the environment suitable for synthesized one may be not applicable for the naturally formed one

spring, small group
Conclusion:
morality lead to the difference

3) 推测(Prephrase: mentally formulate your answer to the question stem)：
the temperature
4) 选项分析：选E
*选项解释不提供固定思路，请根据自己的理解对每一错误选项给出错误原因和类型的解释(无关选项思考清楚为什么无关)，对正确选项分析其与题干逻辑链的关系。
A irrelevant season and irrelevant new information(young voles)
B total amount of voles cannot help explain why the size of groups in different seasons change
C eating habit of the rodents(totally irrelevant and not helpful)
D can explain why the voles live together but cannot explain smaller group in spring
E from spring through early autumu:discard-small group;in winter:the threat disappear and the voles live together again.

   五   
1) 计时：52s
2) 逻辑链Situation
*完整模式：

2  the dolphins are long-lived
怪异点：
their offspring are less competitive in the wild
3) 推测(Prephrase: mentally formulate your answer to the question stem)：

2大致的方向没有问题，没有分析得不对

小花儿绽放

1. 0:36
C: incompetent detective
P: solved smaller % of cases than others
H: incompetent can only be indicated by % of cases solved

2.比较难想出来H是什么
P-form in lab: fullerenes, in nature: fissures; fullerenes needs special conditions
C-the state of earth’s crust exactly when carbon naturally formed in fullerenes could be known
H-fullerenes had been formed naturally——not good enough, shows no relation between P&C but only C
(inspired by the answer) the special conditions of fullerenes is exactly what the state of crust is, without other influences.

还没做完，下次补上。

4.  2:00 2:40
P-seasonal difference group size
C-seasonal reason for mortality of young—wrong, 过度理解, seasonal difference death rate of young
H-the young decide the group size, no others—not good enough, seasonal reason for different death rate of young
A: E

5. 3:00
O-后代寿命短于野生的
P-feed several times a day喂多次; half food a day吃减半; first are no difference than wild
E-second has some differences with wild

在我们CR小分队的共同努力和老大的鼎力支持下，每日逻辑练习终于完成了改进工作，我们都小激动了一翻。正...

Mark一下

有点纠结

顶楼主！

今天第一天先做三道，等会还要做sc pronoun的split练习，加油呀！
1.--->20s
premise: because he solved a much less cases than the other polices.
conclusion:C is a bad detective
prephrase: The number of cases cant represent the capability of a policeman. Maybe he usually deals with difficult cases.

Aright. This statement can weaken the conclusion
Birrelevent. This statement is irrelevent neither with cases nor with C's capablity compared with the other police
Cirrelevent. This statement is irrelevent with C and his case---->support
Dsupport
E irrelevent.This statement is irrelevent with C's case and C's capablity

2.50s
premise: because the finding of xxx in lab was in specific condition
conclusion: the scientists should be provided a chance to test the case for evaluating the hypothese that xxx was really formed in the Earth at that time
backgroud info: xxx was first found in the lab and it was usually found in the nature.
prephrase:weaken---the scientists didnt need to test the case because the finding in lab has already sufficient to demonstrate.

Akept for the first round. right
Bthis statement is irrelevent with the lab
Cirrelevent. more closely related with the background info
Dthis statement focus on the naturally arranged xxx irrelevent with the premise
Esupport
答案选D这道题整个题干都理解错了…是说（BG）这种物质是在特定的自然条件下才能形成，（premise）如果能在实验室里把这种特点的条件还原出来，（conclusion）那么就能还原出当时的地理情况——weaken这种方法不能成立因为有其他的障碍

3.---->23s
premise:because it cost more for a therapeutic project to be carried out
conclusion:it is less likely that this project will operated.
background:although therapeutic project is more efficient than the emergency treatment to the falling old.
prephrase:weaken---the project will be operated because it will save more money than the emergency project if it is carried out.

Athe selection talks about the length the elder follow the program which is relevent to the premise and conclusion.
Bthe selection talks about the difference between the caring place for the elder.irrelevent
Ckept for the first round.right
Dit talks about the new feature of the thera project. irrelevent
Eit talks that the thera project is really spend much. but irrelevent and a bit of support.

补昨天的内容！
4.--->45s
premise:V's group size varies from autumn to Winter. Autumn to Winter has a greater group size and other seasons has smaller group size.
conclusion:The mortality【死亡率】 among the young breeds is the reason why the group size varies.
background:（重看了一次）V lives in a prairie role. the family usually consist of more than one family.
prephrase:support--->it is the mortality!! makes the group size varies!is it any other evidence support this saying or there are no other statements oppose that.

Akept for the first round. the selection is irrelevent to the mortality but related to the proportion of young voles. there can have other causes that the young voles proportion increases.
Birrelevent to the seasonal change
Cirrelevent to the seasonal change
Dkept for the first round. right
Eweaken.
正确答案是E，错因是理解错了premise——大group是春夏，小group是秋冬。这个记不得要回去确认。

5.--->35s
premise:the adult dolphins live healthier because of the feeding program
conclusion:however, the offspring are expected to live shorter than the offspring of the wild dolphins
bg info:there is a feeding program in a beach that the dolphins get half as much as food they need everyday.
prephrase:maybe their offspring lose the ability to find food and less chance to exercise to build up their healthy body.

Aweaken. also, Shark is unrelated to the topic
Bfemale dolphins are not related to the topic
Cirrelevent. it claims that two kinds of dolphins are the same
Dirrelevent. cant explain why low life
Eright

1 A 11:22
2 D 01:42
3 C 02:10
4 E 01:24
5 E 01:19
1. P: C solved smaller percentage of cases than other detectives did
    C: C is incompetent.
inferrence：percentage≠absolute numbers
A---C‘s cases are more difficult than other’s
B---we don’t concern about what did C do before he became a detective
C--- what resources are equipped is unrelated
D---past event is unrelated
E--- when other detectives are hired is unrelated.
2.P：F requires a distinctive condition
  C: this discovery could help evaluate the hypothesis about the state of crust
Weaken: P can not help evaluate the hypothesis
3. P1：emergency treatment cost 11000
   P2: new program reduces chance of fall but cost 12500
   C: this program cannot be justified
Weaken: although the cost is higher, this program has other indirect benefits.
4. P: V live in large group from autumn through winter; V live in small group from spring through autumn.
   C: seasonal variation in group size can be explained by mortality among young V.
   GAP: the mortality of young V
5. P1: adult dolphin are healthy
   P2: their offspring have a lower expectancy than offspring of dolphin feed in the wild.
   explain: point out the difference between the dolphin that benefit from the program and that feed in the wild
