：一般疑问句
1、一般疑问句以be,have情态动词或助动词开始，要求以yes或no回答。有时也用certainly/perhaps/not at all回答，句子通常用升调。
例如：
Are you a student? am/no I am not.
Can you speak english? am/no I can not
Have they been living here for 20 year? have/ haven′t.
2、如果是单个实义动词，一般现在时要在主语前加助动词do或者does,过去时要加助动词did,而主语后的谓语动词须用动词原形。
例如：
Does he do his homework every evening?
Does she go to school yesterday?

1、特殊疑问句一般以疑问代词who/whom/whose/which/what和疑问副词when/where/why/how以及how引出的词组how many/how long等开头，不能用yes或者no来回答，句子通常用降调。
2、语序：当疑问词或由其所修饰的词不作主语时，用一般疑问句语序。
疑问词+一般疑问句
当疑问词或由其所修饰的动词作主语时，用陈述句语序。
疑问句+陈述句
例如：
When did you begin to learn english?
