真心求教各位NN和斑斑 OG12-Q112 错误选项的解释

teddybearj4

112. As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with
such vision.


(A) As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it
would be rated about 20/500, or legally blind if it were an adult with such vision.
(B) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500, or legally blind as an adult.
(C) As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally blind if an adult.
(D) A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind.
(E) As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which
would deemed legally blind for an adult, would be rated about 20/500.




这道题的正确答案选D没有问题。但是感觉上ABCE涉及指代、分号、定语从句修饰、句子结构、语意好多东西，想把这几个错误选项的考点都挖尽了。但是有好几个知识点自己还不是很清楚，真心请求NN、斑斑们的帮助啊！！！！！！！！！！

(A)As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it
would be rated about 20/500, or legally blind if it were an adult with such vision.

1、OG解释：It begins with a subordinate clause, whose subject is a baby; the subject of the main clause, it appears to refer back to baby. However, reading the main clause reveals that it is intended to refer to the sense of vision the first time it is used and to the baby the second time.这句话的意思是第一个it逻辑上到底应该指代a baby还是a sense of vision？根据平行指代it只能指代a baby呀？OG的意思是说这个it指代不清了吗？同样后面的那个it指代的是什么？后面的it应该是跟前一个it指代一样的吗？

(B)A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500, or legally blind as an adult.

1、or legally blind的主语是什么？我查了有别人的讨论帖上说“or legally blind”的主语跟that定语从句的主语一样应该是sense of vision，而vision不是人是不能用blind，逻辑上这个的主语应该是baby。

(C)As a baby emerges from the darkness of the womb, its rudimentary sense of vision would be rated about 20/500; qualifying it to be legally blind if an adult.

1、C选项明显的错误就是分号后面不是一个完整的句子。

2、我有个疑问就是前面的主句是不是没有因果关系，所以不能用as写成一个有因果关系的句子？

3、“its rudimentary sense of vision would be rated about 20/500”这句话是不是逻辑上也跟原句的意思不一致？看D选项(with a rudimentary sense of vision that would be rated about 20/500)觉得感觉意思是只能说本身这种病的得病几率是20/500，并不是说是baby出现的这种病是在10/500的几率？

(E) As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which
would deemed legally blind for an adult, would be rated about 20/500.

1、which是指代sense of vision，然后跟的which的句子里的逻辑主语是不一致的，去掉which的从句，后面its rudimentary sense of vision would be rated about 20/500的错误与C选项一致。

此题的关键在于blind一词，因为只有人可以blind, vision不可以blind。别的考点几乎都可以忽略。(A) As a ba ...

看一下！

Glad it helps!!我是觉得你思考得真的很深入，这点很好，不过就怕走到了另一个极端——只见树木不见森林 ...

Ron这种思想其实不可取：
1. 你怎么知道错误选项里的所有错误？
2. 正确选项里所有的点都绝对正确的吗？

做了很多题之后发现，GMAT里很多错误选项与正确选项的某些差异点，语法或逻辑上并没有错；而正确选项也有其不合理的地方。如果我们把错误选项的正确部分当做错误、而把正确选项的错误当作正确作为rule of thumb，那做下一个类似题的时候，只会继续错。GMAT的选择题是选Best，不是选Correct。所以很多时候得去对比，哪个错的更少。难题和争议题，往往就是正确答案也有问题，才让大家陷入纠结。

回到这题来，这题考了一些国人不知道的一些常识，导致这个20/500让一堆人理解错误。
而我看B选项时，我觉得vision would be rated legally blind，也可能是可以的。rate还有评估、评价的意思。所以blind可能是vision中的一个等级，其他等级说不定还有good、common、bad（谁知道呢？），这种没有上下文的情况下， 大家又没有20/500这样的常识（我也看成这是个概率，虽然觉得太高了。。。）。谁能排除没有“blind“可以是vision的一个评估等级呢？

补了翻译，了解了这个常识之后，才觉得恍然大悟。

神帖！很有用！谢谢

Intended meaning确实是从选项A读出来的，不是从先找到正确答案然后再想meaning.

GMAT出题本来就是这样，哪怕A选项再egregious，也会让读者能通过common sense读出来作者想要表达的意思是什么，然后顺着这个意思去找语法和逻辑都正确的且表达作者原意的那个选项。

baby姐的各种回答，一语惊醒梦中人嘞！谢谢啦

E选项，which  would deemed legally blind for an adult，这个本身就错误了：would后面至少应该为原型吧，这里是deemed。
另外，这个修饰读起来总觉得别扭，不直接。。。for an adult
这个句子读起来哈残疾

如果纯从句意理解确实像从正确句倒退出来的，不靠谱

deem 的用法一般是 someone deem something ..., 所以至少应该是 would be deemed

至于说blind的用法，有没有谁找到形容视觉，而不是形容人或物的例子？
