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 wom
with a rudimentary sense of vision that would b
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 wom
with a rudimentary sense of vision that would b
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.
我选的B ,答案选D。为何B后面or legally blind as an adult这句话的主语不能指是前面的 a baby呢？

因为 or legally blind as an adult是that would be rated about 20/500,

or legally blind as an adult这个修饰vision的定语从句中的一部分，应该是

would be rated, or（ would be） legally blind这种结构吧？

OR看并列关系，VISION和LEGALLY BLIND不能啊。。。

justabeginning

还是没懂，是我太笨了么：（

1楼正解，是or后面如果不是完整句子，主语要一致。

justabeginning

主语和谁一致，为何B选项，逗号后面or legally blind as an adult这句话的主语不能指是前面的 a baby？

Sunfisher006

A中的it为什么第一指的应该是sense of vision

wanghonglia

是 a baby 把，按照句子结构来看
b 是错误的  a baby  legally blind as an adult
这话完全木有意义呀，完全曲解了
而且 在and前面有逗号，and后面应该是完整的句子
S***，and ******是错误的
S***，and S***才正确
and和or都是连词，用法应该一样，所以B错了
