英语反义疑问句疑惑
Sarah had her washing machine repaired the day before yesterday,______she?
A hadn't
B haven't
C didn't 这道题为什么不选A 不是这里是 had sth done吗?
had sth done 没有错,但是这里的had 不是情态动词,所以反义句要提取助动词did
然后反义didn't
选C
如还有疑问~欢迎追问
再问: had done不是情态动词? 为什么 难道后面是补充说明吗?
再答: 这里的had是行为动词,因为是谓语啦,我剖析给你看~
Sarah had her washing machine repaired the day before yesterday,didn't she?

Sarah 主语
had 谓语(过去时)
her washing machine 宾语
repaired 宾语补足语
the day before yesterday 时间状语
,didn't she?反义句

明了了吧
