http://www.beatthegmat.com/mba/2010/07/06/how-to-find-the-point-in-an-rc-passage
(1) You do NOT want to learn or comprehend every single thing that the passage says
(2) Know your goals:
(a) Find The Point
(b) Find the purpose of each paragraph
(c) Know where (in which paragraph) to find different kinds of detail
(3) Practice sticking to your timing and practice abbreviating heavily
(4) When you review your work, also review how you read and took notes on the passage

(1) Understand what The Point is: the single primary reason why the author bothered to spend a bunch of time writing this passage
(2) Read actively; think critically about the purpose behind different pieces of information in the passage and look for language that foreshadows what might be coming next.
(3) Know the kinds of structures that you might see when you read a passage so that you can recognize similar patterns and anticipate what The Point might be.
(4) When you review your work, also review The Point. Now that you’re done, do you still think you were right about The Point? If not, why not? In future, how might you get The Point right the first time?

Ron关于with开头句子的解析：
when you start a sentence with "With ...", this modifier should modify the subject and/or action of the following clause.

e.g.with three separate walls around its exterior, the city was nearly impregnable to enemy attacks.in this case, it's the city that has "three separate walls around its exterior", and this modifier is intimately related to the following clause (it's the reason why the city is impregnable to enemy attacks); hence, this "with" modifier is used correctly.

by the same logic, the original sentence (from the problem) would be implying, absurdly enough, that "archeological evidence" itself HAD "shipbuilding traditions".

关于prepositional phrase的一些总结（尤其是with）：
in general, prepositional phrase modifiers are flexible -- they may require the reader's common sense to resolve their meaning.

for instance, the following two examples are both correct:
-i bought a belt with a removable buckle.
-i bought a belt with my gift certificate.
in the first of these examples, “with a removable buckle” modifies the noun “belt”. in the second example, “with my gift certificate” modifies the action of buying the belt.

*comma+modifier要考虑的两个要点（RON）：

1) when you use a COMMA -ING modifier after a clause**, you should actually satisfy TWO requirements:
-- the modifier should modify the action of the preceding clause, as you have stated;
-- the subject of the preceding clause should also make sense as the agent of the -ING action

*C选项的comma+VING结构不对（RON）：

COMMA + -ING modifiers must modify the preceding clause, but the -ING participle must also apply to the subject of the preceding clause.therefore, the use of that comma+ing modifier would imply that the islets themselves are stimulating disputes. that's not true.

*关于D选项this不能裸奔所引发的知识点啊（Ron）：
choice (d) uses "this" as a standalone pronoun. that's pretty much never acceptable in a formal written sentence.
if you're going to use "this", you should use it as an adjective: this thing, this finding, this statistic, etc.

also, here's some "extra credit" knowledge:
there ARE constructions that can stand for the abstract information in an entire clause (unlike pronouns, which are limited to standing for actual nouns). chief among these are the COMMA + NOUN modifiers.
however, the presence of "because" at the beginning of choice (d) would preclude the use of those modifiers as well.

here's an example:
studies have shown that X is 60 percent of Y, a finding that has shocked most observers.
studies have shown that X is 60 percent of Y; this finding has shocked most observers.

--> both correct. note that "a finding", following the comma, or "this finding", standing alone after the semicolon, stands for the entirety of the clause that comes before it; you couldn't use "which" here, because "which" would automatically refer to Y.

because studies have shown that X is 60 percent of Y, this finding has shocked most observers.
--> incorrect. the presence of "because" at the beginning of the first clause means you can't use "this finding" anymore.
[这个错误的结构和D是一样的】

this / these /that/ those-----> in place of nouns only when you modify them.
it/they/ them------>in place of nouns

pronoun ambiguity sample quesiton OG verbal #71  #19

S-V agreement:
Things CANT be subject
-objective of verbs
-objective of prep.
-subordinate clause(everything you would eliminate in SV agreement problems)
Problems X is Y
-If anything before the verb that can be subject, then that is the subject
-If NOTHING before the verb can be subject, then you have a backward construction
e.g. on the table (prep. phrase) are two cell phones

If you have a compound subject(X and Y), or a list  (x, y, and z)
then you should treat it as you would treat a single plural noun(unlesss you have constuction such as the latter)
correct:James and Michelle (one word) met to discuss their homework.
correct:James met with Michelle to discuss her/Michelle's homework

Be EXTREMELY suspicious about below structure: if the ACTION is the intended object of the prep., then this structure is incorrect
of+noun+V-ing
e.g. Wrong: there is no evidence of my brother stealing the candy.
we want evidence of stealing but not evidence of my brother
e.g. There is no evidence of my brother's stealing candy. Horribly AWKWARD

of+noun+V-ing is ONLY corret if the actual noun if the intended object of the prep.

全划线句子怎么快速做题，今天看到baby的贴子，借鉴：
其一，这是全划线题目；第二，视觉上宏观地“瞄”一下选项，很明显的感觉就是：有那么几个chunks来回移动，在不同的选项里出现的位置不同——这就是典型的考察modifier placement的特征。于是我们就找到一个关键split: modifier placement. 注意，Ron说过：并不是只有点状的（一个词或者几个词）才能叫做split，modifier本身就是一个split. 当你找到这个split的时候，就宏观地（以chunck为视觉单位）扫读每个选项，读到你觉得modifier placement有问题的时候，立刻咔嚓。

1.Keep track of your thinking on your scrap paper. Your first pass is to decide between “definitely wrong” and “maybe.” Your second pass is to determine which of the “maybe” choices you’re actually going to pick.
2.Read the original question in its entirety. Unless you can pinpoint a specific error, don’t eliminate answer choice A.
3.Whenever you find an error, immediately scan any remaining choices and eliminate those that repeat the same error.
4.Practice making educated guesses and study how you are going to make the decision when you do have to guess

对于全划线句子，由于可能原句本来就各种不agreement，导致读不懂，那么就继续往下读，直到读到那个选项觉得OK了，意思非常清楚了，往往就是正确选项。

需要搞清一个语法点：平行省略问题

1.pronoun ambiguity is not an absolute rule
GMAT will tolerate pronoun ambiguity if
-context is obvious
-the pronoun is parallel to the intented noun
-the pronoun is not paralle to other nouns.
e.g. take the pizza out of the box and put it into the oven.

The results of the company's cost-cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.
A. which increased five percent during the first three months of this year after it fell
B. which had increased five percent during the first three months of this year after it had fallen
C. which have increased five percent during the first three months of this year after falling over the last two years
D. with a five percent increase during the first three months of this year after falling
E. with a five percent increase during the first three months of this year after having fallen
Correct answer is C. (my choice is E)

Ron's explanation on why which is better than with
in general, "COMMA + prep phrase modifier" is an adverbial modifier, meaning that it modifies the entirety of the preceding clause.
in this sentence, we don't want an adverbial modifier, since it doesn't make any sense for this modifier to apply to the entire preceding clause.
rather, we want a modifier that will only modify the noun at the end of the preceding clause (i.e., "profits"). since this is the exact function of a "which" modifier, that's the modifier we want here
Ron's explanation on why after falling not after having falling
"after having VERBed" is, in general, a redundant construction -- the word "after" is already there, so "having" doesn't contribute anything.
if you see this construction, you should generally be able to replace it with “after VERBing”.  it's possible that there are exceptions, but i can't think of any at this time.

选E的错误思路分析：
CDE当时觉得都没有明显错误
2个split: with/which & falling/had falling
虽然觉得which表达很清晰，但觉得也许with句子结构更加简洁
had falling比falling更加突出强调了之前profit一直在跌

误区在：
并不是没有从句，一个句子就更简洁，句子是不是wordy/awkward的判断标准并不是句子结构的复杂程度决定的
after already indicate the order and timing. after+v-ing一般可以替换after+having Ved

Thelonious Monk, who was a jazz pianist and composer, produced a body of work both rooted in the stride-piano tradition of Willie (The Lion) Smith and Duke Ellington, yet in many ways he stood apart from the mainstream jazz repertory.
a)        same
b)        Thelonious Monk, the jazz pianist and composer, produced a body of work  that was rooted  both
c)        Jazz pianist and composer Thelonious Monk, who produced a body of work rooted
d)        Jazz pianist and composer Thelonious Monk produced a body of work that was rooted
e)        Jazz pianist and composer Thelonious Monk produced a body of work rooted both

Ron's explanation on the 1st Caluse:
this is a special idiom.  if you preface someone's name with a noun describing their occupation (or other word describing what that person does), WITHOUT AN ARTICLE, you DO NOT use a comma.

if there's an article, you DO use a comma. if it's an adjective, you DO use a comma.

example:
Jazz pianist and composer Thelonious Monk ... --> correct
A jazz pianist and composer, Thelonious Monk ... --> correct
Creative and original, Thelonious Monk ... --> correct

Why we shoud eliminate "both"?
Main problem of this sentence is PARALLELISM: idiom: both X and Y --> X and Y must be parallel.

错误原因：没仔细读句子 meaning好好看
                其他4个选项都有both,想当然就觉得both没问题
