有关情态动词 can与第一人称 的一般疑问句怎么改
改一般疑问句通常分一下几种情况：1、原句的谓语动词是be动词(am,is,are,was,were...）或情态动词(can,may,could,will...),则将句中的be动词或情态动词提至句前，句子其他部分的语序不变，标点变为问号。
eg.1.You are a teacher.——Are you a teacher?2.You are working.——Are you working?3.They can sing and dance.——Can they sing and dance?2、原句的谓语动词是实义动词，则需根据原句的主语借助助动词，原句中的动词用原型。
eg.1.I like music.—— Do you like music?2.Wang Hong likes music.—— Does Wang Hong like music?注意： 以上只提到了现在时态的一些情况，但是改一般疑问句不论时态，通常都适用以上规则。
情态动词能can与助动词does在一个句子里吗，例如Does he can do it
情态动词能can与助动词does在一个句子里吗，例如Does he can do it他能做这件事吗能在同一个句子里，但是不能同时组合成一个谓语部分。

是错误的。
只能说：Does he do it?Can he do it?
