we didn't say anything until my father came back(改同义句) WE ( )( )( )until my father came

问题描述:

we didn't say anything until my father came back(改同义句) WE ( )( )( )until my father came

是不是打错了(后面也少了一个back啊),只能变成:
We didn't say anything until my father came back.
= We (said nothing) until my father came back.
