特殊疑问句在英语中是一种用来询问特定信息的问句，通常以疑问词开头，例如who, what, when, where, why和how等。以下是一些例子：
Who：Who is your best friend？
What：What did you buy yesterday？
When：When is the next train？
Where：Where are you？
Why：Why are you so happy？
How：How do you know？
回答特殊疑问句时，通常不能使用yes或no，而是要根据问题提供具体的答案。例如：
Who：He is my best friend.
What：He bought a bike.
When：The next train arrives at 5:30 PM.
Where：I am at the library.
Why：He is happy because he passed his exam.
How：He found out by checking the internet.
特殊疑问句的语序通常是“疑问词 + 一般疑问句”，但在某些情况下，疑问词作为主语或主语的定语时，语序可以是陈述句的语序。
