1、ACE的句子结构都有问题：A中的第二个were多余，前面已经有谓语were built…；C中each that…，each是名词，后跟that引导的定语从句，该定语从句省去后只余下一个名词；E有两套主谓结构，settlement…were built on…… each had been connected，中间没有连词；
2、D中的and with前面没有平行对象；
3、正确答案B中的of up to 600 rooms each是插入语，修饰structures，正常语序应该为：each of the structures has up to 600 rooms。with…connected是with引导的独立结构。

C)  works and it will sell them online as either electronic books or as
D)  works, and selling them online as either electronic books or as
E)  works, and it will sell them online as either electronic books or

错选E. E错在句子结构上，“, and it will”这里的逗号与and要连接两个完整的句子并列，即与主句publisher has announced…并列，无法与定语从句中的will publish并列，除非去掉逗号。
OG11：a pair of comma是隔开插入语（修饰成分），不影响整体句子结构。
所以E选项中的”,under which…works,”就成了修饰division的成分，and it will sell…和主句并列改变了原文要表达的意思。
至于C中不加逗号的and it will sell中的it多余，wordy。
A: correct，to be sold表示有将要的意思（to be sold不定式作定语，”被用来网上出售的”which will be sold）

C中的and it weighs无法与is as long as并列，只能与主句is the smallest..并列。
D: correct
BE的weighing优先修饰computer，歧义

49. It was only after Katharine Graham became publisher of The Washington Post in 1963 that it moved into the first rank of American newspapers, and it was under her command that the paper won high praise for its unrelenting reporting of the Watergate scandal.
A It was only after Katharine Graham became publisher of The Washington Post in 1963 that it moved into the first rank of American newspapers, and it was under her command that the paper won high praise for its unrelenting reporting of the Watergate scandal.
E Moving into the first rank of American newspapers only after Katharine Graham's becoming its publisher in 1963, The Washington Post won high praise under her command.
该题两个并列结构中的it不是形式主语，是强调结构，即“it+be动词+强调部分+who(m)或that+其他部分”。
强调结构中的it不作句子结构中的任何成分，无所指代，故认为不与后面有所指的it冲突。
但形式主语（也叫先行主语）不一样，形式主语it指代了句子的真正主语，因为有所指，所以句子中如果再出现其它有所指的it，就冲突了。

E the Anti-Cybersquatting Consumer Protection Act, passed in 1999, and it allows companies to seek up to $100000 in damages against those who register domain names with the sole intent of selling
A: passing应该改成passage，这里强调结果不是过程
B: in 1999有修饰歧义，按原文应该是passage；they指代有歧义，应该指names，同时要用被动时态
sell在这里是不及物动词，卖出/售出（也改变了原意），they应该指names，但有指代those的歧义。
C: correct
DE错误的原因相同，and it allows…是完整的独立句子，与主句并列，无法与which引导的定语从句并列。

She published historical novels, as well as a non-fiction study of women.
as well as的特殊用法（我认为是作conj.）：linking noun groups, adjectives, clauses. You can use as well as to link clauses. However the second clauses must be a non-finite clause beginning with an –ing form.
例句：She negotiates the licences as well as ordering the equipment.
B选项中用as well as连接动词原形是错误的。
A: correct
DE中的a …size单复数与engines that have不一致

注意未划线部分的代词their, BD中的tree不一致。
AB: among倒装，主语应该是the rate所以用单数is
C: their的指代存在歧义，离它最近的是sunspot cycles
on earth放置句首修饰整个句子，不符合逻辑。
未划线部分的as seen是否要紧跟其修饰的名词？
应该是这样子的，所有修饰成分都应该紧跟其修饰对象，除非前面有插入语。
D: believed应该用被动(句子结构不完整)
E: correct

D: correct
E: 宾语从句应该有that；过去完成时没有道理，for doing表达目的也不如to do好

C: 过去完成时没有意义，descended需要被动
D: descended需要被动，and后面需要加that

162. Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).
A. acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate
B. acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating
C. act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating
D. they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates
E. they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
A: correct
B: 无主句
C: act 的谓语结构应该是状语结构；无主句
D: 改变原意 （even though与前面的although重复，都是从句）
E: 改变原意 （although…, they act…, but they accelerate…，三个分句中第一个是although引导的从句，中间是主句，但后面又跟一个but引导的并列分句。这个句子结构是没有问题的）
thus副词不能连接并列的谓语act, keep（应将to改为连词and）

原文的acting and keeping是作benefit的伴随状语，解释如何benefit Earth。Although ice particles benefit..., they also accelerate the destruction... 原文要表达这样一个对比：尽管有益，也有害。
E. they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
而E呢，如果这样的句子结构不算错，那它表达的意思也不符合逻辑。
Although ice particles benefit..., they act to keep...这两个分句之间本来没有这层让步转折含义（原文的关系应该算是递进吧），但因为they act...成了独立的句子，所以与前面的although状语从句联合，就不符合逻辑意思了。
再往后面的but... 又与although重复了（重复使用连词）。

172. The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed by the performance, will fall over and play dead.
A. broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom,
B. broadens the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom,
C. broadening the flesh behind its head the way a cobra does and feigning repeated strikes, but it has no dangerous fangs and no venom, and
D. broadening the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom, and
E. broadening the flesh behind its head the way a cobra does, feigning repeated strikes, but with no dangerous fangs and no venom, and
原句结构: The snake puts on an impressive bluff, hissing and rearing…, broadening…and feigning…, but it has no dagerous fangs and no venom, and eventually, [插入语if its pursuer is not cowed by the performance,] will fall over and play dead.
The snake puts on…, doing…, doing… and doing…, but it has…, and will fall…
AB: 两个动词之间应该有连词
A的结构是The snake puts on…, doing and doing, broadens…, doing but doing, will fall…，三个并列谓语put, broaden, will fall之间缺少连词。
B的结构是The snake puts on…, doing and doing, broadens…and feigns, will fall…，也是结构有问题，and的位置不对。
C: correct
D: broadening 和 feigns不平行；but with no 不如用句子表达好
E: broadening 和feigning之间必须有连词
注意：
1、but with no这种介词结构在GMAT里，都倾向用完整的句子方式进行表达
2、目的状语并列必须用连词不能用逗号，以前考过
