Not until he finished his work _______go home. A he did B did heCwill be D he will

Answer 1

选B。
Not until...和...not ...until...的意思都是一样的.用法上Not until 位于句首,主句采取部分倒装.部分倒装就是把谓语部分的操作词移到主语前.
结构是: Not until+从句/时间,主语(助动词/情态动词+主语+谓语的其他成分+其他)
Not until he finished his work did he go home.
(=He did not go home until he finished his work.)

B

Answer 3

B did he
