I really don't know where it was that he found his lost sister whom he hadn't seen for almost twenty years.

我真不知道他在哪找到了他失散20多年的妹妹.

成分分析,主句:I really don't know…… 后面是一个宾语从句,还原一下语顺:it was where that he found……这个从句又是一个It is ……that……的强调句型,副词where就是联系主句和从句的关系词,在从句中作地点状语,宾语从句中只需要把关系词提前即可.比如:

I don't know who you are.我不知道你是谁.
