疑问句是按照句子的语气分出来的一个类，它与陈述句、感叹句、祈使句的最大区别就是它的疑问语气；是问一些事情的，表达的内容并不是陈述，所以是不确定的；主要有四大句型，一般疑问句、选择疑问句、特殊疑问句和反意疑问句；而反意疑问句是高考英语的语法项目之一。
疑问句简介
疑问句是实际交流中常用的句式，疑问句分为一般疑问句、选择疑问句、特殊疑问句和反意疑问句。一般疑问句通常用来询问一件事情是否属实。
答句通常是“Yes.”或“No.”。所以一般疑问句又称作“是非问句”。选择疑问句提出两个或两个以上可能的答案供对方选择。以疑问词开头，对句中某一成分提问的句子叫特殊疑问句。特殊疑问句有两种句型结构，是实用英语学习中需要掌握的。它们一种是“疑问词＋一般疑问句”，另一种是“疑问词＋陈述句语序”，此时的疑问词在句中用作主语，或是修饰主语。

肯定句改为一般疑问句小学生都会了
就是把句中的be动词提前，其他语序不变，句末加上问号。
如果是没有be 动而是有实意动词的句子，就用助动词do /does /did 中合适的形式放句首，其他语序不变，句末加问号。
