标题: PREP SC-005 求大神解答

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

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

答案选A,

求问各位大神为什么C不对?我觉得C更好啊?


1.难道是单复数不一致吗?A team...is...,having...我觉得也没问题啊,还是有别的非语义问题?

2.还是因为语义问题,因为重点在于后面的detected而不是working


求大神解答,真的好蒙逼

是这样的,现在分词和不定式都有加have的情况,也就是having done和to have done。这里添加了have不是表示“完成时”,而是表示“先时性”,也就是这个动作是发生于它的主句的谓语动词的,例如一道OG题的正确选项(我简化了一点):
Neuroscientists, having amassed a wealth of knowledge over the past twenty years, are now drawing solid conclusions about how the human brain grows.
这个句子就表示,神经科学家是先攒了多年的知识,然后才下的结论。

用在这道题目中,如果选项(C)正确,那么它就表示,天文学家是先发现的气团,然后才工作在天文台的,这显然是不符合逻辑的~

Hope that helps~
