疑问句中动词的用法

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.
也就是说,在疑问句中,只要原句是分词的,改成疑问句中也用分词,分词的形式不受句式的影响
