英语的一般疑问句的变化是和其陈述句有关系的。
陈述句中有am,is,are,was,were的把这些词提到主语的前面就变成一般疑问句了。例如He is a teacher. 一般疑问句就是Is he a teacher? We were at school yesterday. 一般疑问句就是Were you at school yesterday?陈述句中有助动词或情态动词的把助动词或情态动词提到主语前I can sing. 一般疑问句就是Can you sing? They will go to Shanghai. 一般疑问句就是Will they go to Shanghai?陈述句有没有be 动词或助动词或情态动词的,在句首加助动词。比如He plays soccer.一般疑问句就是Does he play soccer?
