An international team of astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter, the solar system's largest planet.

(A) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to have 5 to 15 times the mass of Jupiter

(B) astronomers working at telescopes in the Canary Islands and Spain has detected at least 18 huge gas spheres estimated to be 5 to 15 times Jupiter's mass

(C) astronomers is working at telescopes in the Canary Islands and Spain, having detected at least 18 huge gas spheres that are estimated at 5 to 15 times the mass of Jupiter

(D) astronomers, working at telescopes in the Canary Islands and Spain, and has detected at least 18 huge gas spheres estimated at 5 to 15 times the mass of Jupiter

(E) astronomers, working at telescopes in the Canary Islands and Spain, has detected at least 18 huge gas spheres they have estimated to be 5 to 15 times Jupiter's mass

答案选A,我选E。A中estimated to have5 to15不是应该是estimated to be吗？ working前加了逗号不是也可以修饰前面的名词吗？

astronomers, working at telescopes in the Canary Islands and Spain, has detected at least 18 huge gas spheres ，动词当然是has啦～～～^_^

我只是想确认一下，逗号加动名词，是不是也可以非限定性修饰前面的名词，

逗号 + V-ing:

这种结构应该V-ing是2种情况:

1-主句主语的发出的动作,

2-前面整个句子(整件事情)导致了V-ing短语的这个结果.EG: The price is sharply increasing, driving people crazy.
