Diesel engines burn as much as 30 percent less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases that have been implicated in global warming.

(A) of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases that have
(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gases having

as well as doing something 位于逗号后，对主句的谓语动作做出补充，为正确的习语结构
本句使用了这样一种基本句型：A did one thing, as well as doing another thing.        这种句型属于 as well as 的一种使用方法，朗文给出的例句为：The organization gives help and support to people in need, as well as raising money for local charities.

此处前面有提到一种gas(co2),所以后面可以用the other表示其他gas
就算不了解这个用法，其他的选项有明显错误可以排除，要大胆做出选择

Patience Lovell Wright, whose traveling waxworks exhibit preceded Madame Tussaud's work by 30 years, became well known as much because of having an eccentric personality as for having skillfully rendered popular public figures in wax.            

(A) well known as much because of having an eccentric personality as for having skillfully rendered popular public figures in wax
(B) well known as much for having an eccentric personality as for her skillful wax renderings of popular public figures
(C) well known as much because of her eccentric personality as she was for her skillful wax renderings of popular public figures
(D) as well known for having an eccentric personality as having skillfully rendered popular public figures in wax
(E) as well known for her eccentric personality as for her skillful wax renderings of popular public figures
  
1 because of doing 的搭配基本上都是错误的
2 as much for……as for……前后要完全对称。
as…as…引起介宾比较的用法可以有多种。以此句为例，介宾结构为 for A/B，句子既可以是：She became well known as much for A as for B;        也可以是She became as well known for A as for B.        在as…as提示的比较结构中，相比较的事物要求形式对称、内容平行
GMAT SC解题的精髓，在于选项之间的比较。在本题中，如果出现  became well known as much because … as for …        的选项，在语法没有错误的情况下，符合上述[1]所说的满足功能对称，因此有可能是正确的选项，考生不能仅凭because和for结构不平行而排除该选项。应该先保留该选项，再仔细辨别其他选项中是否有更好的――即功能、结构两层次都平行的选项。本题的E，即为功能、结构均平行，故最佳。关于“比较选项差别”这一GMAT改错题的重要方法，本题是最好的例子之一。

OG204. In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should acquire certain characteristics and partly because crossbreeding is said to provide hybrid vigor.
(A) in part that their steers should acquire certain characteristics
(B) in part for the acquisition of certain characteristics in their steers
(C) partly because of their steers acquiring certain characteristics
(D) partly because certain characteristics should be acquired by their steers
(E) partly to acquire certain characteristics in their steers

注意体会their steers should acquire certain characteristics 和 certain characteristics should be acquired by their steers所表达含义的差别前者是说要取得steer的某些characteristics，从E中可以更明确的看出这个意思。而后者是说steers要得到某些characteristics，但是不明确是steers的还是别的什么的。

Cassiopeia

Answer to Question 204
Choice E is best; it best indicates purpose for crossbreeding-- partly to acquire. In A, in part that does not grammatically connect the underlined portion to the first part of the sentence (the independent clause). In both Aand B, in part is not parallel with and partly in the nonunderlined portion. Choice C causes a misreading, suggesting that the steers' acquisition has caused the crossbreeding. D awkwardly and illogically shifts to the passive voice: certain characteristics should be acquired by their steers; the steers, however, are not agents in the acquisition.
这句话中，partly……partly……中的内容就不是完全平行，而是逻辑平行。在一些句子长度长、难度高的句子中，平行结构只要满足功能、逻辑对称，可以不对结构做出严格的要求。如果功能对称或逻辑对称不能满足，即使满足了结构对称，也是错误的答案。

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

(A) Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he
(B) Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made,

A.         正确，两个动词时态均使用正确。伽利略没有发明望远镜是个事实，所以本句的第一个动词invent，
适用一般过去时。如果使用过去完成时，则表示伽利略是在built his own device之前没有发明望
远镜，暗含在此之后可能发明了望远镜之意。这使得句子逻辑含义出现瑕疵，相比之下，一般过
去时更加准确。而望远镜在1609年这一过去的时间点之前，就已经被发明了，所以本句的第二
个动词made，适用过去完成时。

Because she knew many of the leaders of colonial America and the American Revolution personally, Mercy Otis Warren was continually at or near the center of political events from 1765 to 1789, a vantage point combining with her talent for writing to make her one of the most valuable historians of the era.

(A) a vantage point combining with her talent for writing to make
(B) a vantage point, when combined with her talent for writing, that made
(C) a vantage point that combined with her talent for writing, and it made
(D) and this vantage point, which combined with her talent for writing to make
(E) and this vantage point, combined with her talent for writing, made

A. to make表将来含义，而句子描述的是过去已经确定的事实，时态含义不符；combining应该为combined
在剩下两个选项进行比较时，应该仔细考虑它们之间的差别。如本题AE选项之间的比较，读者应考虑：a vantage point，是主动发出combining这个动作，还是被combined？
这个vantage point，是“将要”to make,        使得她成为重要的历史人物；还有这个句子陈述历史事实，这个vantage point在过去已经使得made她成为了重要的历史人物？
通过这两点考虑，我们并不难选出正确答案E。考生一定不可看到a vantage point that…这种结构，就不假思索的认为这种结构就一定是正确的。
