在疑问句中,动词用什么型

记住：在疑问句中，动词恢复成原形（但是分词除外，即现在分词和过去分词）
She *goes to school every day.
--Does she *go to school every day?
He *wrote to his mother yesterday.
--Did he *write to his mother yesterday?
I am *doing* some washing at home.
---Are you *doing* some washing at home?
They have *been* to Beijing.
--Have they *been* to Beijing？
即分词不变。
