@转换:He didn't go to bed until he finished his homework last night. 是要改until～～～额～可以将它换成before吗？要两句，呢还可以换成：He got to bed when to he finished his homework last night.吗？或者是He got to bed until he finished his homework last night.吗？？？
我说了关键在until的啊～～～ 不能去改动其他的动了吗!!!!!!!!!!!!!!!!!!

He didn't go to bed before he finished his homework last night.
He went to bed when he finished his homework last night.
He went to bed after he finished his homework last night.
he went to bed after finishing his homekork last night.
He finished his homework before he went to bed last night.

He had to finish his homework before he went to bed.

Not until he finished his homework did he go to bed.
It's until he finished his homework that he went to bed.

不能！！！！！！！！！！！！！！！！！！when后头能加to= =until后还接主语奥？你狠有创造性.........
