问题描述：
A good friend of mine from ___ I was born showed up at my home right before I left for Beijing.
-----填when.请各位大大帮我分析下句子成分,尤其是那个from是干嘛的.请不要乱说,什么补语状语宾语定语一块来的.
答
主语 A good friend of mine
定语 from ___ I was born （介词from加上宾语从句,修饰名词friend）
谓语 showed up
状语 at my home（地点） right before I left for Beijing（时间）（两个状语修饰动词show up)
翻译 我从小一起长大的朋友在我动身去北京之前出现在我家里
