被动语态变主动语态,各位帮个忙

A story of Edison's boyhood will be told by our teacher.
原句的意思：一个关于爱迪生少年时代的故事将被我们老师讲。
改为主动语态则为：我们老师将要讲一个关于爱迪生少年时代的故事。
翻译成英文则为：Our teacher will tell us a story of Edison's boyhood.

Our teacher will tell us a story of Edison's boyhood.

Our teacher will tell a stiry of Edison's boyhood.

Our teacher will tell us a story of Edison's boyhood.
原句是将来时态，所以改为主动的将来时态！~~~
