Take away：so...as to...与so...that...表达的意思一样，均为“太…以至于…”，一种因果关系。他们的区别在于，so...as to...用于主语和to后面的动作的发出者一致时，而so...that...中，主语与that之后的主语不需要一致。
CONTINUING...

Split#1：固定搭配 not...but...，只有选项C符合

A选项：condensing的主语是clouds,错误；

A选项：announcement和其提到的事件之间有一个时间差，因为事件先发生，然后才announce,所以用过去的过去时态；

argument以成功率作为考量因素：成功率80% means 找了10个人募捐，有8个人愿意捐。（至于这八个人捐了多少donations size，无所谓）
A：S大学募捐者在联系过去未捐款的捐赠人时，成功率和其他大学募捐者一样 （总成功率=联系捐过款的+联系没捐款的，S的总成功率远大于其他大学，但没捐过款的成功率等于其他大学--------联系没捐过款的占总成功率的比例远远小于其他大学比例，----不成功）
B：成功率跟捐款量没关系 （也许捐款量看似能影响对fund-raiser的评估，但文中只有一个评估标准：成功率）
C：1.成功率跟捐款量无关 2. argument说的是 raiser联系到的人中多是过去捐过的（联系的很轻松），C中说的是大多数donation来自于没联系的过去捐过的，跟提干信息无关

choice d, to make作为目的状语，make的发出者是computer company，公司不能够使公司成为第一，而应该是dea

1） 看到and的时候要弄清楚what should be grouped.
A. (Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide) and, (if it strikes Earth, it can do tremendous damage to part of the planet but probably not cause planet-wide destruction.)
B. Scientists have identified an asteroid, 2000 BF19, (that is about half a mile wide) and (that, if it were to strike Earth, could do xxxx)

2. if-then patterns

if do, then will do /can do
if did, then would do/could do
if had done, then would have done/could have done

charge 直接跟prince，需要at。可以说sell....at a price.

Ron: NEVER split on word choice before parallelism.
1) 实质平行: dash应该是书，排除ACD
2) 形式平行: dash前是 [author]'s [books], dash后用[author]'s [books]的形式优于[books] by [author].

#the three best novels ever written by a Black American是可接受的，也更清楚每个书有一个作者。类似用法，birds have a four-chambered heart.

1) as 说明是对比，要关注平行，in no other historical sighting与in 1910-1911不平行 (Ron)
2) 去掉状语后的句子是 did Halley's comet cause such a worldwide sensation

这个跟犀牛佩戴collar是相同的思路
条件: aflatoxin + casein => cancer
结论: aflatoxin + milk(containing casein) => cancer
选项A：cacsein有其他的渠道，e.g.peanuts. milk与casein不等价

条件: Recollar => low fertility
结论: substance in tranq => low fertility
选项C: substance in tranq除了recollar没有其他来源。

【求问毕老师】这题很难我第一时间反应过来应该用by the animal's compensating一个名词放于动名词之前，看曼哈顿里提到一个语法规则：如果该名词是动名词的发起者，那么要用所有格，如Mike’s swimming is the product of new coaching techniques. 想问下这条规则背后的原因或逻辑是什么？谢谢~

一定别想当然选词跟原文一样的选项，很多题原文的词都被类比/概括/同义替代了。

题干的Disagree: Collins - You can also say that two people disagree. eg. They can communicate even when they strongly disagree...

The number of which cannot logically refer to the noncount noun population or to the singular wolf, which is used adjectivally here to modify population.
"However" is intended to serve as a conjunctive adverb between the two independent clauses.
A semicolon after area and a comma after however would make the intended function of however clear.
还有比较关键的一点从GMATCLUB上得到了解答：We can say either the size of the wolf population or the number of wolves.
In Choice D, which CANNOT refer to the wolf population because then Choice D will have the phrase the number of the wolf population.
This expression is incorrect the population cannot have any number. Choice A has the same error.

划线部分与非划线部分的连接处，选项之间的差异，非划线部分是一个名词，movement
A：similarity 不能 explained as movement 去掉
B：Thule artifact在从句结构中，语义不对，去掉
C：that一件事不能被explained as movement，去掉
E：解释不能是一个movement，去掉

Take away：as much as 修饰不可数名词，as many as修饰可数名词。
Split#1：hours是可数名词，去掉选项A、C、D
Split#2：more...than...固定搭配，去掉选项B

五个选项中有四个是semicolon结尾的。
Split#1: 第一个or前后平行，去掉选项A、B、C
Split#2: 剩下两个选项对比，发现应该三者并列符合语义，去掉选项E

A. The opening phrase correctly modifies the subject, the
army of terra-cotta warriors;
they must clarify two things about the army of terra-cotta warriors: how old it is and how long it took to complete.
