Quasars, at billions of light-years from Earth the most distant observable objects in the universe, believed to be the cores of galaxies in an early stage of development.
本题答案没有问题,但主语后面的修饰成分却非常怪异,at billions of light-years from Earth the most distant observable objects in the,似乎应该是the most distant observable objects in the universe at billions of light-years from the earth作为同位语?但语序却极其怪异地将at billions of light-years from the earth放在前面,难道是想强调距离吗?这种修饰成分的语序有什么规则没有?
