DAY19
复习内容:背单词、阅读小分队、IR做了一个多元推理题、GWDTN-2的SC和CR、重读baby姐姐关于主动和被动的解释(太精彩了摘录)、重读神猴关于RC的指导(大逻辑和小逻辑的把握)。
今日回顾:
一、主动与被动问题读完后我的心得:
1、抓住原句提供的信息:主语是谁,动词在哪,每个修饰成分的位置本意是想要修饰谁。
2、如果有被动语态,找到每个动词的动作发出者是否有特定人选还是泛指。
3、如果A有明显语法错误,再依据以上的主谓核心关系和各成分修饰关系,去split其他选项。
二、adj+n 和n to be adj的区别问题:
1、adj n这里adj是N的本质特性类,所以警惕v的分词形式在此充当主语的情况。要看v会不会有歧义。
2、n to be adj是n被赋予了adj的属性。such as human efforts/actions/interference/perception/etc
for instance, the following sentence is preferred:
henry bishop was the first musician to be knighted by a british monarch. --> knighting is performed by humans
the following is NOT preferred:
henry bishop was the first knighted musician in britain. --> this makes it seem as though being 'knighted' is an inherent quality with which henry bishop was born, or that he acquired it naturally/accidentally in some other way
三、pronoun的仅有2条原则:
(1). the antecedent must exist
(2). A pronoun and its antecedent must agree in numbe
四、数字比较类题型:数字是否被明确定义
GWD1-Q7: A recent review of pay scales indicates that CEO’s now earn an average of 419 times more pay thanblue-collar workers, compared to a ratio of 42 times in 1980.
- that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times
- that, on average, CEO’s now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times
- that, on average, CEO’s now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio
- CEO’s who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio
- CEO’s now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times
"42 times" is followed by "their pay" and thus well-defined.
"the ratio" clearly refers to the preceding ratio "42 times" (Here the structure is appositive)
所以就说,这里出现的一切数值都定义明确。建议你用这种思路(数值定义是否明确?)
Ron:
the best reason i can give - actually the second-best reason, after 'because they said so' - is because of the EXTREMELY strong logical parallelism between '42 times their pay' and '419 times the pay of blue-collar workers'. that absolute parallelism compels the pronoun and antecedent to be parallel as well.
这个解释非常赞啊!来看看平行关系
42 times their pay
419 times the pay of blue-collar workers'
看吧,pronoun也对应上了,数值也对应上了,毫不含糊!
大D和baby姐的探讨:
Research during the past several decades on the nature of language and the processes that produce and make it understandable has revealed great complexity instead of underlying simplicity.
(A) that produce and make it understandable has revealed great complexity instead of underlying simplicity
(B) of producing and understanding it have revealed not underlying simplicity but great complexity
(C) by which it is produced and understood has revealed not underlying simplicity but great complexity
(D) by which it is produced and understood have revealed great complexity rather than underlying simplicity
(E) by which one produces and understands it have revealed great complexity instead of underlying simplicity
Split #1. "the processes that produce ..." VS. "the processes by which it is produced ..."
baby姐的解答:
Split #1. "the processes that produce ..." VS. "the processes by which it is produced ..."
(1) "the processes that produce ..." is logically sound
Ask yourself: does it make sense to say "the processes produce the language" and "the processes make it understandable"?
Well, I ask this question because this question is important to consider. Only if the answer is "yes", the usage of "the processes that produce ..." is justified.
An example from Ron:
INCORRECT: The restaurant that we ate last Friday was crowded.
(This sentence literally says that "we ate the restaurant" -oh my gosh!!!!)
CORRECT: The restaurant at which we ate last Friday was crowded.
I mentioned the above example because I want to say: when we use essential noun modifier "something that bla bla", we should make sure it is EITHER:
(a) "something" is the subject or object of the "that clause"
OR
(b) "something" is this kind of words: finding, opinion, belief, suggestion, etc. and "that bla bla" is to explain "something" in a clause. --However, this situation does not apply here.
So, back to this question, the answer is "yes".
"the processes" can be the subject. i.e. we can say "the processes produce the language"
Therefore, the usage in A is justified.
(2) potential ambiguity in "the processes by which it is produced"
Consider the following two sentences. Does each of these two sentences make logical sense?
(a) Ancient Chinese produced the language by this process.
(b) This process produced the language.
As we discussed above, (b) makes logical sense.
Look at (a). It also makes sense, right? Using some process, people can produce a language.
So what I mean is:
if you, as a reader, see a sentence written as "the processes by which the language is produced", you may have two logically sound interpretations:
(a) some people (or nationality or whatever) produced the language by the processes
(b) the processes produced the language
So you CANNOT tell who/what produced the language!
--Let me extend beyond this question.
I hear a lot of people say "GMAT prefers active voice to passive voice". Even a GMAT instructor says this in explaining this question. (http://www.beatthegmat.com/nature-of-language-t91077-15.html)
But I want to say: BE CAREFUL!!! Do not AUTOMATICALLY choose the active voice answer choice.
We should understand WHY the particular voice is preferred in the GIVEN situation.
This example illustrates the potential ambiguity embedded in the passive voice. In fact, MGMAT SC Guide has a wonderful example:
INCORRECT: The dealer was asked to sell a painting by Picasso.
Is it "a painting by Picasso" or "the dealer was asked by Picasso"? Ambiguous!
If you change the sentence to active voice, saying "The boss asked the dealer to sell a painting by Picasso." then the ambiguity issue is perfectly resolved.
See? Same logic applies here. "the processes by which it is produced" is ambiguous. |
