we play the violin after school改为特殊疑问句？

特殊疑问句要看针对什么发问。比如：

Who play violin after school?

What musical instrument do you play after school?

When do you play violin?

这句话要改为特殊疑问句，要看你问什么，问主语，那就是Who play the violin after school，如果问干什么，那就是What do you do after school。

如果是在play the violin下面划横线，那么特殊疑问句就应该是： What do you do after school?如果是在violin下面画横线，就应该是： What do you play after school?如果是在时间状语after school下面画横线，那特殊疑问句就应该是： When do you play the violin?

Do you play the violin after school？句中有实义动词，所以加助动词，调整人称，最后把问号加上就行了。

we play the violin after school.
改为特殊疑问句:
1). Who play the violin after school?
2). What do you play after school?
3). When do you play the violin?
