我觉得还是从GMAT例题里体会"as well as"，我个人感觉，通常有"另起炉灶"的意思.如跟前面衔接特别紧密，就不用as well as.记得Ron似乎说过这个比较subtle的语言点。
这道题很典型：http://www.manhattangmat.com/forums/tulipomania-t100.html

谢谢baby姐姐~~
~~~饭饭这里把解释引用过来~~~不涉及版权问题吧~~呦~~担心滴说~~
This sentence can be broken into a Core and Modifier Tree (to be seen in the Sentence Correction Slam, the forum doesn't really display an appropriate table).
Examples of "tulipomania," a term coined from the tulip craze of the seventeenth-century in the Netherlands, include speculative bubbles in South Seas trading rights in the 1720s, Victorian real estate in the 1880s, the U.S. stock market in the 1920s, and the obsession for Beanie Babies in the 1990s.
The tree highlights (or would highlight) a problem with parallelism in the list of four items that are examples of speculative bubbles. According to the sentence, there were speculative bubbles in trading rights, real estate, a stock market and an obsession. The first three represent the items upon which the speculative bubble was built; the fourth does not.
(A) This choice is incorrect as it repeats the original sentence.
(B) CORRECT. This choice corrects the parallelism error by removing the fourth item, the obsession, from the list of things that were speculative bubbles. Now, the sentence says that "examples... include speculative bubbles" in trading rights, real estate and the stock market and "[examples... include] the obsession for Beanie Babies." It is not necessary to repeat the words "examples include" in the second part of the sentence.
(C) While this choice corrects the parallelism error by removing the fourth item, the obsession, from the list of things that were speculative bubbles, it introduces a modifier error. The initial phrase "coined from..." is followed by the noun "examples." However, the term "tulipomania" was coined from the tulip craze; the examples were not coined from the craze.
(D) This choice does not correct the original parallelism error. According to the sentence, there were speculative bubbles in trading rights, real estate, a stock market and an obsession. The first three represent the items upon which the speculative bubble was built; the fourth does not.
(E) This choice does not correct the original parallelism error. According to the sentence, there were speculative bubbles in trading rights, real estate, a stock market and an obsession. The first three represent the items upon which the speculative bubble was built; the fourth does not. In addition,the sentence introduces confusion because it implies that the later examples of speculative bubbles were "included" in, or a part of, the original tulipomania.
This is a ROUGH problem, so don't be discouraged if you struggled with it.
Hope that this is helpful. Warm regards, - Andrew
guest：Andrew:
In your explanation in answering the question, you have not quoted "as well as" which was part of the original question. Did you assume that the quoted term did not make any difference?
Thanks
ManhattanGMAT staff：
The original choice didn't include the phrase "as well as," but the correct answer does.
B. Examples of "tulipomania," a term coined from the seventeenth-century tulip craze in the Netherlands, include speculative bubbles in South Seas trading rights in the 1720s, Victorian real estate in the 1880s, and the U.S. stock market in the 1920s, as well as ... (the obsession for Beanie Babies in the 1990s).
Notice that "as well as" starts a NEW list, one that functions at a higher level. The structure is as follows:
Examples... include
I. speculative bubbles in
a) South Seas trading rights in the 1720s,
b) Victorian real estate in the 1880s,
and
c) the U.S. stock market in the 1920s,
as well as
II. the obsession for Beanie Babies in the 1990s.
The outer list is I and II. The inner list is a, b, c.
You need the "as well as" to make a clear separation from the inner list that is immediately preceding. (In some cases, you can use another "and" in place of "as well as," but that works best when you can repeat a preposition from the outer list.) Hope this is helpful! Chris

Hi,
After reading this sentence, I was not able to identify whether "the obsession for Beanie Babies in the 1990s. " is another example or a part of list of "speculative bubbles in"
Could you please help me in understanding how did you identify that "the obsession for Beanie Babies in the 1990s. " is another example. In other words, please elaborate how did you come up with following structure?
Examples... include
I. speculative bubbles in
a) South Seas trading rights in the 1720s,
b) Victorian real estate in the 1880s,
and
c) the U.S. stock market in the 1920s,
as well as
II. the obsession for Beanie Babies in the 1990s.
ManhattanGMAT stuff：
You can have speculative bubbles in things that are being traded / sold, such as trading rights, real estate, the stock market, etc.
The beanie babies part, though, starts with the word "obsession" - so technically, you'd be saying that there was a speculative bubble in an obsession. That doesn't make any sense - the speculative bubble would be in beanie babies, not in an obsession.
Since none of the choices remove the "obsession" part of the construction, we have to start a new list: examples include speculative bubbles (in A, B, and C) as well as the obsession (for D). Both "speculative bubbles" and an "obsession" can be examples, so that's okay.
