改错I I hope I"ll meet famous someone one day

I hope I"ll meet (someone famous) one day

I hope I'll meet someone famous one day.

I wish（that） I"ll meet someone famous 。

改法其实有很多种，答案不唯一。

当形容词遇到someday,anybody等不定代词时，要后置，改为someone famous即可

I hope that I can meet someone famous one day. 或I wish that I would meet someone famous one day都可以. hope 实现的可能性大于 wish ，所以hope 后跟 can加强语气 ，表示能够；would 表示 虚拟，表示与事实相反，对应wish ，实现的可能性不大

I I hope I"ll meet someone famous one day
