高中英语单选独立主格结构
_______an earthquake in gansu province,we dicided to form a rescue team to get there helping the victims in the earthquake-stricken area.
A.There had been B.There has been C There being D.There having been
知道是独立主格 想知道C 错在什么地方 CD区别是什么?

答案

doing作非谓语时,在时间上与主句谓语可前,可后,也可同时.
但若想明确表达前后有间隔,用完成式才可以.
there being an earthquake,刚地震完,或正在地震中,
there having been earthquake ,地震过后（有间隔）
所以此题最佳答案选用了d.
答案c没有错,只是略显的仓促.刚地震完或正在地震中就决定组织救援队去震区,不符合常理.太危险.若真有此事,精神可嘉.冒死前往救援啊.
