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.
划线的which,是不是仅仅指代vision?A of B, which这样的结构,是不是which就指代B?
例如:通过单复数判断which的所指: Changes in sea level result not only from changes in water temperature, which affect water density, but also from the melting of glaciers. 通过affect来看,which指代的是changes,而不是temperature,但位置上,which紧跟在temperature后 。
