一般疑问句也叫Yes/No问句，变化规则如下：
1.句子中有be动词时，将be动词提前，首字母变大写，句末用问号。

例： He is a teacher. Is he a teacher?
You are a boy. Are you a boy?
2.句子里有情态动词can(能；会)时，将can提前，首字母变大写，句末用问号。

例：He can swim. Can he swim?
You can play football. Can you play football?
3.句子里没有be动词和can 时，要借助助动词do/does, 将do/does提前，句末用问号。

例：I like apples. Do you like apples?
He has a pen. Does he have a pen?
*回答的时候，用什么文就用什么回答，问的谁就用谁回答。
