I still remember the acident and the troubles___has caused to me.
问题描述：
I still remember the acident and the troubles___has caused to me.
空上填it,求具体解释,为什么?
答
it
it 指代前文的the accident,在定语从句中做主语
I still remember the acident and the troubles(这里省了个that/ which) 【it】has caused to
由于which或者that 在定语从句中作caused 的宾语,所以省略了
翻译：
我还记得那次事故以及这次事故给我造成的种种麻烦.
