不定式、现在分词和定语从句的区别

类比的对象：实验室合成的富勒烯和自然形成的富勒烯
推翻类比：类比对象的不同点
天然存在的富勒烯以先前未知的晶体结构排列。因此与实验室合成的不同

题目的意思很简单，但问题问得很奇怪，有谁理解的，讲解下。

Date to ... ago
Date at ... old

increase by

直接consider A B就可以判断了

succumb 屈服于

感觉这里to也没问题跟found也有关系 found ... to...

我觉得D选项是错在improve response rate for SUCH mail. D选项是通过提高定制广告质量来提升定制广告的回复率。但题目的意思是说明定制广告为什么能提高广告回复率，E更符合。

more than和be likely to

请问：Bruce answered all the questions excepting the last one. 除了最后一个问题外，布鲁斯都答出来了。为什么这里不能用except呢？

CD搬运：
第一个分析：
1。 which 指代不明：根据句意， which 应该指代extremes of temperature, precipitation, and storminess，但是在 E 中，which 只能指代 storminess；

2。 to impact the most on people 表达有问题，既不应该用表目的的to do，impact ... on 也不地道。

3。 主宾倒置，强调的中心完全变了。

第二个分析：
A项：关于温室效应的讨论集中在...,但是气象学家指出最明显的效应是…

E项，关于温室效应的讨论集中在...,但是气象学家指出...是影响人们最大的。

很明显，A为正确选项。因为A紧紧围绕关于温室效应的讨论，用but来对比。而E项，but后的气象学家指出的东西与前面的不是一个问题。所以如果选E项，but就没有道理存在。

not until 1955 was it hypothesized—by Wigner and Eisenbud—that tunneling particles sometimes travel faster than light

错选B：根据Though the extreme rapidity of quantum tunneling was noted as early as 1932，可知tunnelling最早在1932年就已经被注意到了

Their grounds were calculations that suggested that the time it takes a particle to tunnel through a barrier increases with the thickness of the barrier until tunneling time reaches a maximum

1）any loose aggregate spinning faster than once every few hours would fly apart 2）asteroids larger than 200 meters across are multicomponent structures or rubble piles
结合起来也就是rubble piles必须同时满足两个条件：1）转速必须低于几小时一次 2）大于200米以上。选项中任意一个条件不符合就可以质疑

其实像这样不常接触到的idoim是可以忽略的... 显然GMAT不是靠组合筛选高分的人
首先举例可以筛掉B & D--Like不能用于举例
compare ACE, 其中C的 as simple as的比较结构错误，通常我们使用as..as是这样用的：as high as that tree， 这里as..as的用法貌似也出现过 是描述一个沙子还是岩石的题目？？？
而E选项的symptomatic of another problem... 这个完全是词性混乱了，没人会说important of another problem,而是importance...
最后得到A

Jacob Burckhardt's view that Renaissance European women "stood on a footing of perfect equality" with Renaissance men has been repeatedly cited by feminist scholars as a prelude to their presentation of rich historical evidence of women's inequality
JB想法是‘女性和男性站在完全平等的基础之上’。这个idea经常被引用用作男女不平等的历史证据。可见JB的想法在学者眼里是反面教材

in works focusing on those middle- and upper-class European women whose ability to write gives them disproportionate representation in the historical record.

she suggests that such verbal opposition to cultural stereotypes was highly circumscribed; women seldom attacked the basic assumptions in the ideologies that oppressed them
分号后面的那句话就是为了具体解释说明：口头上的cutural sterotype是高度受限制的
