大全120，关于句子中心的改变

我笨，我努力

120.    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.（D）

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

我认为D将一个as的伴随结构变为句子的中心结构，有问题。

我觉的E比较好，保持了原有句子的强调中心，the rudimentary sense of vision 做句子的主语。

可以给我一个D优于E的比较好的理由吗？

In choice A, it, the subject of the main clause, seems to refer to baby, the subject of the subordinate clause; thus, A seems to state that the newbom baby, rather than its sense of vision, would be rated 20/500. Similarly, choices B and E use awkward and ambiguous phrasing that suggests that the sense of vision, rather than an adult with 20/500 vision, would be considered legally blind. C incorrectly uses the semicolon, which should separate independent clauses, to set off a verb phrase. The phrase if an adult in C is also illogical, since it states that a baby could also be an adult. D is the best choice.

我笨，我努力

ETS太欺负人了，我任是根据原句看不出，it指代的中心是baby，baby和rate怎么可以挂上钩呢！

不过说实话是D比较好，我做第一遍的时候就做对了，因为那时语法知识还不全，语感判断比较强些。现在好了，考虑多了反而做错了。看来还需加倍努力呀。加油！

能否帮忙解释一下这句话的意思，it would be rated about 20/500     在这里指什么？这种概率吗？
