2)D我觉得很奇怪,A baby..with a rudimentary sense of vision that would be rated about 20/500...这里的would be rated about 20/500应该是用来修饰sense of vision的而不是a baby的吧,那么这句话的前半句简化来说就是A baby emerges from the darkness of the womb with a rudimentary sense of vision。这句话不是一个fragment吗?实在不能理解,求牛牛解释。-- by 会员 yuexuannan (2012/11/19 16:08:09)
