daisy最近想了想,其实我们逻辑练习一直以来积累了很多的题目,从OG到PREP到Bible都重复更新了几次, 很多过去的帖子都可以重新被挖回来好好利用的,练习的内容还是那些题目,关键是通过每天的练习领悟逻辑的要领, 所以逻辑小分队组织大家重回第二季练习,有兴趣的CDer请跟帖练习。
题目链接请见: 本帖1楼
练习方法如下: 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(答案为白色字体隐藏了,请选定可见),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。
一、逻辑小分队运行规则: 1)一系列为20天的练习,加入逻辑小分队的同学需要坚持每天的练习。
2)按每日练习进度完成每天5题的题目,当日10点前把练习完成,把做题情况回帖到当日练习的帖子中。
3)在本帖中打卡考勤: a. 每天完成作业后在本帖回复:作业日期+作业编号(例如2.22+【3-8】) b. 不能在当天10点前完成的要提前在本帖请假:请假+作业日期+作业编号,补回练习后把作业链接发到本帖。
4)每日设立讨论当天练习的题目以及其他GMAT问题的时间: 在当期练习的Q群讨论,每晚10点开始,有问题的要准时提出。
5)一系列的练习中有5次以上不完成练习的惩罚就是请离队。
6)如何加入逻辑小分队? 加入逻辑小分队唯一的要求就是能坚持一个系列的每日练习。 报名规则: 请跟帖回复:报名(请注明:更新成员or练习成员)+预计考G时间。 a. 每期更新成员为5名,请在本帖报名,逻辑小分队会视报名情况进行组织调整,选出一名组长负责整个系列练习的组织和监督。 b. 每期练习成员人数不限,同样需要在本帖报名,同样按要求需要坚持每日练习。 c. 报名成功后,我会用短消息告诉你逻辑小分队的讨论群,欢迎加入我们的大家庭。
二、加入逻辑小分队的福利: 1)让各位亲爱的追梦人拥有互助互爱的平台,让你的追梦之路不再孤单。 2)享受与往届逻辑小分队成员以及逻辑版版主交流的机会。
三、第三季练习介绍: 1)每日跟帖练习模式: 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。
Example: 1. “Life expectancy” is the average age at death of the entire live-born population. In the middle of the nineteenth century, life expectancy in North America was 40 years, whereas now it is nearly 80 years. Thus, in those days, people must have been considered old at an age that we now consider the prime of life. Which of the following, if true, undermines the argument above? (A) In the middle of the nineteenth century, the population of North America was signi?cantly smaller than it is today. (B) Most of the gains in life expectancy in the last 150 years have come from reductions in the number of infants who die in their ?rst year of life. (C) Many of the people who live to an advanced age today do so only because of medical technology that was unknown in the nineteenth century. (D) The proportion of people who die in their seventies is signi?cantly smaller today than is the proportion of people who die in their eighties. (E) More people in the middle of the nineteenth century engaged regularly in vigorous physical activity than do so today. (白色部分为隐藏选项)
【跟帖练习示例】 1) 计时:30s 2) 逻辑链Situation(刚开始练习先写好完整逻辑链,练习到逻辑链基本清晰的时候尝试尽量简化信息、提炼最精简的逻辑链): *完整模式: Background Information: Life expectancy is the average age at death of the whole population. Premise: Life expectancy in mid-nineteenth century North America was 40 years; now it is almost 80. Conclusion: What we think of as the prime of life must have been considered old in that earlier era. 3) 推测(Prephrase: mentally formulate your answer to the question stem): the average age at death is 40 years≠the usual length of life is around 40 some other reasons that lead to the outcome: 极端值大, ?rst-year infant mortality was extremely high in earlier era. 4) 选项分析:选B *选项解释不提供固定思路,请根据自己的理解(可参考Powerscore Critical Reasoning Bible)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。
