Astronomers have uncovered evidence that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting dazzling radiation that could have disrupted Earth's protective ozone layer and sunburned our Stone Age ancestors.

A that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting

B that a star as bright as the full moon exploded into view 340,000 years ago, emitting

C of a star that was as bright as the full moon exploding into view 340,000 years ago and that it emitted

D of a star as bright as the full moon, exploding into view 340,000 years ago and emitting

E of a star as bright as the full moon that exploded into view 340,000 years ago and that emitted

虽然看出了A.B 同位语从句的用法更好但是B中的emitting的逻辑主语为什么是从句的star不是主句的Astronomers呢？一般这种主句+从句，doing 的用法， doing的逻辑主语都是从句主语么？求大神帮忙解答TT谢谢~~~

印象中，看到过解析说分词修饰的是preceding clause，是修饰的前边的句子，并不是主句。只不过大部分时候“，+ 现在分词”的前面就是主句。B选项里边emitting前边那个星星爆炸已经完整了，应该是就近修饰前边紧挨这的句子

从句意理解，emit是分词做结果状语，表达星星爆炸的影响。如果是修饰宇航员，隔的太远了

A：exploding 看起来像在修饰full moon
B：evidence that a star （as...）exploded xx years ago, emitting xxx. 很完美
CDE 把 a star当做evidence的一个介词短语，就跟后面的动作毫无关系了。explode变成修饰evidence
