向各位求教做逻辑对瓶颈。 这几天花了大量时间看CR，做题思路 按照先判断类比推理，方案，或者统计枚举等 然后再如果是 strength 等话 CQ是什么； 可能因为对这个逻辑思路不熟悉 觉得非常耗时间这个过程，而且正确率一直都在6-70之间不能提高。 想看看各位都是什么样对思路做CR

纠结CE，认为C是are geared to enhance athletes' performance and (to enhance) their preparation，句意如果是这样不可以么？还是说不能用那个their？为什么E一定更好呢，E也用了个them指代平行结构前一般的内容athletes。求解答，谢谢老师！

B:智力情况不可观，人们可能会社交社会孤独；即智力情况良好，人们才会进行更多的社会交往。属于因果方向颠倒问题

于是.......我就彻底懵了......

in general, you shouldn't think of comparison sentences as "omissions"; you should think of them as finding elements that match most closely to their counterparts in the other part of the sentence.
in this case, the point is that "over the age of 30" and "under it" are exactly parallel elements, creating a sensible comparison. that's all you really have to find.

有一个不是很理解的地方，希望老师帮忙解答一下。
我本来认为这种带比较性质的句子是需要补充省略的部分的，然后我以为full sentence长这样：more babies were born to women over the age of thirty than (those were born to women) under it.
但是后来我在曼哈顿里看到RON这样说：

no, you can't write the sentence like that.
but don't try to "fix" the sentences. the above sentence is incorrect for reasons that the gmat exam doesn't test, so it's not worth worrying about.

目标：减少恶作剧电话；不影响火情报告
方案：取消火警亭

不知道为什么打了一串式子发不出来也删不掉。。。总之我想问无论y大于0或者小于0，都能推出来这个结论啊。。。

用continue约束力强排除BD可以哇？

说错了 D不能认为是独立主格么？

C选项 不能认为是独立主格么？

平行结构理解没问题，有一个疑问是，如果有选项是forming.... and laying是不是会更好？感觉这里作宾语，谓语动词has been是弱约束

A. KL and HK have such floated measures (as building more ......) , perching ...------括号中的as building ....是measures的定语还是补语？（我感觉是补语或者同位语？）

想了半天觉得B是独立主格是不是没有表达因果关系，A理解成了分词短语，觉得重心在plummeting，becoming 就给选了。嗯，错得清楚方便一万吨拍的瞄准。。。。。。

D选项的定语从句两个by对吗? new patterns of behavior and expression can be passed on from one to another by imitation and practice by the kind of curiosity
